Important notes

Minimum supported versions

Note: If you need to support older OS versions, please use an older version of this plugin.

Native environment required

Note that this plugin is intended for use in a native mobile environment. It will NOT work in a browser-emulated Cordova environment, for example by running cordova serve or using the Ripple emulator.

Building for Android

In order to avoid build problems with Android, please make sure you have the latest versions of the following Android SDK components installed:

Installation

Using the Cordova/Phonegap/Ionic CLI

$ cordova plugin add cordova.plugins.diagnostic
$ cordova plugin add cordova.plugins.diagnostic --variable ANDROIDX_VERSION=1.0.0
$ phonegap plugin add cordova.plugins.diagnostic
$ ionic cordova plugin add cordova.plugins.diagnostic

AndroidX Library

This plugin uses/depends on the AndroidX (Jetpack) libraries (these supersede the Android Support Library which is no longer used by this plugin since cordova.plugins.diagnostic@6).

This plugin pins default versions of the legacy and appcompat versions of the library in its plugin.xml however you can override these to specify different versions using the ANDROIDX_VERSION (legacy) and ANDROIDX_APPCOMPAT_VERSION variables at plugin installation time, for example:

$ cordova plugin add cordova.plugins.diagnostic --variable ANDROIDX_VERSION=1.0.0 --variable ANDROIDX_APPCOMPAT_VERSION=1.3.1

Specifying modules

Since cordova.plugins.diagnostic@4 the plugin is split into optional functional modules. The reason for this is so you can choose to install only those parts of the plugin you'll use and therefore not install redundant code/components/frameworks.

By default, all the modules will be added to your project when you install the plugin.

You can specify which modules are installed by adding a <preference> to your config.xml which specifies the modules you wish to add as a space-separated list. Module names should be capitalised.

The preference takes the form:

<preference name="cordova.plugins.diagnostic.modules" value="[list of modules]" />

For example, to explicitly include all optional modules:

<preference name="cordova.plugins.diagnostic.modules" value="LOCATION BLUETOOTH WIFI CAMERA NOTIFICATIONS MICROPHONE CONTACTS CALENDAR REMINDERS MOTION NFC EXTERNAL_STORAGE" />

To install only the core module and no optional modules, leave the preference value blank:

<preference name="cordova.plugins.diagnostic.modules" value="" />

IMPORTANT: After adding the preference to your config.xml, you'll need to uninstall then re-install the plugin to your project to apply the changes:

cordova plugin rm cordova.plugins.diagnostic --nosave && cordova plugin add cordova.plugins.diagnostic --nosave

Available modules

The following optional modules are currently supported by the plugin:

IMPORTANT: It's vital that the preference be added to your config.xml before you install the plugin, otherwise the preference will not be applied and all modules will be added. This is because, due to limitations of the Cordova CLI hooks, this plugin must use the npm install process to apply the module preferences and this runs before the Cordova CLI when installing a plugin. If you change the modules specified in the preference, you'll need to uninstall then re-install the plugin to your project to apply the changes.

Reporting issues

IMPORTANT: Please read the following carefully. Failure to follow the issue template guidelines below will result in the issue being immediately closed.

Before opening a feature request issue, please do the following:

Usage

The core plugin module is exposed via the global cordova.plugins.diagnostic object and it aliases all functions and properties of the other optional modules. If a function is called on the core module for an optional module which is not installed, a JS error will be raised by the core module.

Core module

Purpose: Generic and miscellaneous functionality.

Platforms: Android & iOS

Configuration name: N/A - always installed, regardless of whether the module preference key is present in config.xml.

switchToSettings()

Platforms: Android and iOS

Opens settings page for this app.

On Android, this opens the "App Info" page in the Settings app.

On iOS, this opens the app settings page in the Settings app.

cordova.plugins.diagnostic.switchToSettings(successCallback, errorCallback);

Parameters

Example usage

cordova.plugins.diagnostic.switchToSettings(function(){
    console.log("Successfully switched to Settings app");
}, function(error){
    console.error("The following error occurred: "+error);
});

switchToWirelessSettings()

Platforms: Android

Switches to the wireless settings page in the Settings app. Allows configuration of wireless controls such as Wi-Fi, Bluetooth and Mobile networks.

cordova.plugins.diagnostic.switchToWirelessSettings();

switchToMobileDataSettings()

Platforms: Android

Displays mobile settings to allow user to enable mobile data.

cordova.plugins.diagnostic.switchToMobileDataSettings();

permissionStatus constants

Platforms: Android and iOS

Both Android and iOS define constants for requesting and reporting the various permission states.

cordova.plugins.diagnostic.permissionStatus

Android

The following permission states are defined for Android:

⚠ Since it's impossible to distinguish between NOT_REQUESTED and DENIED_ALWAYS using the native Android runtime permissions API (they both return the same constant value), this plugin attempts to distinguish the difference by using HTML5 local storage to keep track of which permissions have been requested since the app was first installed. On requesting a permission for the first time, an entry is put into local storage against the permission name. If the user then selects DENY_ALWAYS, the plugin uses the flag in local storage to distinguish this from NOT_REQUESTED.

Some things to watch out for:

If Android Autobackup is enabled (which it is by default ), Android does not backup app permissions after uninstall but does backup HTML5 local storage. This may lead to a permission being reported by the plugin as DENIED_ALWAYS when the actual status is NOT_REQUESTED. To avoid this you may want to disable Android Autobackup. You can do this using the cordova-custom-config plugin, for example:

<platform name="android">
    <plugin name="cordova-custom-config" version="*"/>
    <custom-preference name="android-manifest/application/@android:allowBackup" value="false" />
    <custom-preference name="android-manifest/application/@android:fullBackupContent" value="false" />
</platform>

iOS

The following permission states are defined for iOS:

Addtionally, for notifications permissions:

Example

if(somePermissionStatus === cordova.plugins.diagnostic.permissionStatus.GRANTED){
    // Do something
}

getPermissionAuthorizationStatus()

Platforms: Android

Returns the current authorisation status for a given permission.

Note: this is intended for Android 6 / API 23 and above. Calling on Android 5.1 / API 22 and below will always return GRANTED status as permissions are already granted at installation time.

Parameters

Example usage

cordova.plugins.diagnostic.getPermissionAuthorizationStatus(function(status){
    switch(status){
        case cordova.plugins.diagnostic.permissionStatus.GRANTED:
            console.log("Permission granted to use the camera");
            break;
        case cordova.plugins.diagnostic.permissionStatus.NOT_REQUESTED:
            console.log("Permission to use the camera has not been requested yet");
            break;
        case cordova.plugins.diagnostic.permissionStatus.DENIED_ONCE:
            console.log("Permission denied to use the camera - ask again?");
            break;
        case cordova.plugins.diagnostic.permissionStatus.DENIED_ALWAYS:
            console.log("Permission permanently denied to use the camera - guess we won't be using it then!");
            break;
    }
}, function(error){
    console.error("The following error occurred: "+error);
}, cordova.plugins.diagnostic.permission.CAMERA);

getPermissionsAuthorizationStatus()

isRequestingPermission()

Platforms: Android

Indicates if the plugin is currently requesting a runtime permission via the native API. Note that only one request can be made concurrently because the native API cannot handle concurrent requests, so the plugin will invoke the error callback if attempting to make more than one simultaneous request. Multiple permission requests should be grouped into a single call since the native API is setup to handle batch requests of multiple permission groups.

var isRequesting = cordova.plugins.diagnostic.isRequestingPermission();

Example usage

var isRequesting = cordova.plugins.diagnostic.isRequestingPermission();
if(!isRequesting){
    requestSomePermissions();
}else{
    cordova.plugins.diagnostic.registerPermissionRequestCompleteHandler(function(statuses){
        cordova.plugins.diagnostic.registerPermissionRequestCompleteHandler(null); // de-register handler after single call
        requestSomePermissions();
    });
}

registerPermissionRequestCompleteHandler()

Platforms: Android

Registers a function to be called when a runtime permission request has completed. Pass in a falsey value to de-register the currently registered function.

cordova.plugins.diagnostic.registerPermissionRequestCompleteHandler(successCallback);

Parameters

Example usage

function onPermissionRequestComplete(statuses){
    console.info("Permission request complete");
    for (var permission in statuses){
        switch(statuses[permission]){
            case cordova.plugins.diagnostic.permissionStatus.GRANTED:
                console.log("Permission granted to use "+permission);
                break;
            case cordova.plugins.diagnostic.permissionStatus.NOT_REQUESTED:
                console.log("Permission to use "+permission+" has not been requested yet");
                break;
            case cordova.plugins.diagnostic.permissionStatus.DENIED_ONCE:
                console.log("Permission denied to use "+permission);
                break;
            case cordova.plugins.diagnostic.permissionStatus.DENIED_ALWAYS:
                console.log("Permission permanently denied to use "+permission);
                break;
        }
    }

restart()

Platforms: Android

Restarts the application. By default, a "warm" restart will be performed in which the main Cordova activity is immediately restarted, causing the Webview instance to be recreated.

However, if the cold parameter is set to true, then the application will be "cold" restarted, meaning a system exit will be performed, causing the entire application to be restarted. This is useful if you want to fully reset the native application state but will cause the application to briefly disappear and re-appear.

Note: There is no successCallback() since if the operation is successful, the application will restart immediately before any success callback can be applied.

cordova.plugins.diagnostic.restart(errorCallback, cold);

Parameters

Example usage

var onError = function(error){

Motion module

Purpose: Motion/fitness tracking permission.

Platforms: iOS

Configuration name: MOTION

motionStatus constants

Platforms: iOS

Constants for reporting the various states of Motion Tracking on iOS devices.

cordova.plugins.diagnostic.motionStatus

The following permission states are defined:

Example

if(status === cordova.plugins.diagnostic.motionStatus.NOT_REQUESTED){
    cordova.plugins.diagnostic.requestMotionAuthorization(successCallback, errorCallback);
}

isMotionAvailable()

Platforms: iOS

Checks if motion tracking is available on the current device. Motion tracking is supported by iOS devices with an M7 co-processor (or above): that is iPhone 5s (or above), iPad Air (or above), iPad Mini 2 (or above).

cordova.plugins.diagnostic.isMotionAvailable(successCallback, errorCallback);

Parameters

Example usage

cordova.plugins.diagnostic.isMotionAvailable(function(available){
    console.log("Motion tracking is " + (available ? "available" : "not available") + " on this device");
}, function(error){
    console.error("The following error occurred: "+error);
});

isMotionRequestOutcomeAvailable()

Platforms: iOS

Checks if it's possible to determine the outcome of a motion authorization request on the current device. There's no direct way to determine if authorization was granted or denied, so the Pedometer API must be used to indirectly determine this: therefore, if the device supports motion tracking but not Pedometer Event Tracking, the outcome of requesting motion detection cannot be determined. Pedometer Event Tracking is only available on iPhones with an M7 co-processor (or above): that is iPhone 5s (or above). No iPads yet support it.

cordova.plugins.diagnostic.isMotionRequestOutcomeAvailable(successCallback, errorCallback);

Parameters

Example usage

cordova.plugins.diagnostic.isMotionRequestOutcomeAvailable(function(available){
    console.log("Motion tracking authorization request outcome is " + (available ? "available" : "not available") + " on this device");
}, function(error){
    console.error("The following error occurred: "+error);
});

requestMotionAuthorization()

Platforms: iOS

Requests motion tracking authorization for the application.

The native dialog asking user's consent can only be invoked once after the app is installed by calling this function. Once the user has either allowed or denied access, calling this function again will result in an error. It is not possible to re-invoke the dialog if the user denied permission in the native dialog, so in this case you will have to instruct the user how to change motion authorization manually via the Settings app.

When calling this function, the message contained in the NSMotionUsageDescription .plist key is displayed to the user; this plugin provides a default message, but you should override this with your specific reason for requesting access - see the iOS usage description messages section for how to customise it.

There's no direct way to determine if authorization was granted or denied, so the Pedometer API must be used to indirectly determine this: therefore, if the device supports motion tracking but not Pedometer Event Tracking, the outcome of requesting motion detection cannot be determined.

cordova.plugins.diagnostic.requestMotionAuthorization(successCallback, errorCallback);

Parameters

Example usage

cordova.plugins.diagnostic.requestMotionAuthorization(function(status){
    if(status === cordova.plugins.motionStatus.permissionStatus.GRANTED){
        console.log("Motion tracking authorized");
    }
}, function(error){
    console.error(error);
});

getMotionAuthorizationStatus()

Platforms: iOS

Checks motion authorization status for the application. There's no direct way to determine if authorization was granted or denied, so the Pedometer API is used to indirectly determine this.

cordova.plugins.diagnostic.getMotionAuthorizationStatus(successCallback, errorCallback);

Parameters

Example usage

cordova.plugins.diagnostic.getMotionAuthorizationStatus(function(status){
    if(status === cordova.plugins.diagnostic.permissionStatus.GRANTED){
        console.log("Motion authorization allowed");
    }
}, function(error){
    console.error(error);
});

});

registerNFCStateChangeHandler()

Platforms: Android

Registers a function to be called when a change in NFC state occurs. Pass in a falsey value to de-register the currently registered function.

This is triggered when NFC state changes so is useful for detecting changes made in quick settings which would not result in pause/resume events being fired.

Returns details of external SD card(s): absolute path, is writable, free space.

The intention of this method is to return the location and details of removable external SD cards. This differs from the "external directories" returned by cordova-plugin-file which return mount points relating to non-removable (internal) storage.

For example, on a Samsung Galaxy S4 running Android 7.1.1:

which are on non-removable internal storage.

Whereas this method returns:

[{

    details.forEach(function(detail){
        if(detail.canWrite && details.freeSpace > 100000){
            cordova.file.externalSdCardDirectory = detail.filePath;
            // Then: write file to external SD card
        }
    });
}, function(error){
    console.error(error);
});

Platform Notes

Android

Android permissions

Some of functions offered by this plugin require specific permissions to be set in the AndroidManifest.xml. Where additional permissions are needed, they are listed alongside the function that requires them.

These permissions will not be set by this plugin, to avoid asking for unnecessary permissions in your app, in the case that you do not use a particular part of the plugin. Instead, you can add these permissions as necessary, depending what functions in the plugin you decide to use.

You can add these permissions either by manually editing the AndroidManifest.xml in /platforms/android/, or define them in the config.xml and apply them using the cordova-custom-config plugin, for example:

<platform name="android">
    <plugin name="cordova-custom-config" version="*"/>
    <custom-config-file target="AndroidManifest.xml" parent="/*">
        <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
        <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
    </custom-config-file>
</platform>

Note: If you're using Phonegap Build (or some other Cloud build system), cordova-custom-config won't work because it relies on hook scripts. For Phonegap Build you can use <config-file> blocks so long as you use cli-6.5.0 or below (support for <config-file> blocks was dropped in cli-7.0.1).

Android runtime permissions

Android 6 / API 23 introduces the concept of runtime permissions. Similar to iOS, certain "dangerous" permissions must be requested at runtime in addition to being listed in the Android manifest.

Runtime permissions only apply if the device/emulator the app is running on has Android 6.0 or above. If the app is running on Android 5.x or below, runtime permissions do not apply - all permissions are granted at installation time.

This plugin supports checking and requesting of Android runtime permissions.

"Dangerous" runtime permissions

The plugin defines all dangerous permissions available up to API 33 as a list of constants available via the cordova.plugins.diagnostic.permission object. The following permissions are available:

Android 11+ runtime permissions

Android 11 introduced a new option for the user when granting runtime permissions: "Only this time"/"Ask every time". This allows the user to temporarily grant a permission only for the current app session: the requested permission will be available to the app during the current session but when the app is restarted, permission will be revoked and the app will have to request it again. This causes a problem for this plugin because it is unable to detect that the permission has been silently revoked by Android in the new app session.

When runtime permissions were introduced in Android 6.0, there was already a deficiency in the Android permissions model: the Android SDK provides no way to differentiate between a permission that has not been requested yet (NOT_REQUESTED) or has been permanently denied (DENIED_ALWAYS) - they have the same programmatic state. Therefore this plugin uses local persistent storage to flag when a given permission has been requested and granted via the plugin. So if Android indicates NOT_REQUESTED/DENIED_ALWAYS, the plugin uses the state of the persistent flag to determine if that permission has been requested before and therefore can differentiate between NOT_REQUESTED and DENIED_ALWAYS.

This worked fine up until Android 10, however the "Only this time" option added in Android 11 causes a problem: There's no way for the plugin to tell if the user pressed "Only this time" or "Allow always" in the permissions dialog because the programmatic outcome in Android is the same: the permission state is GRANTED. Therefore in both cases, the plugin flags this permission as having been requested. But if the user pressed "Only this time", when the app is restarted the permission is silently revoked by Android and so when the native Android state indicates NOT_REQUESTED/DENIED_ALWAYS, the plugin determines that since the flag has been set for that permission, the state must be DENIED_ALWAYS.

There is no programmatic solution that the plugin can implement to solve this - it is a deficiency in the Android permission states model. There is however a workaround which is to assume that even if the reported permission status is DENIED_ALWAYS, the permission may still be requestable.

Here's a short example of how to do this using the CAMERA permission:


let diagnostic, deviceOS;
let cameraDeniedAlwaysAfterRequesting = false;

function onDeviceReady(){
    diagnostic = cordova.plugins.diagnostic; // alias to shorter namespace
    diagnostic.getDeviceOSVersion(function(osDetails){
        deviceOS = osDetails;
        checkCameraPermission();
    })
}

function checkCameraPermission(){
    diagnostic.getPermissionAuthorizationStatus(function(status){

        // If running on Android 11+ and status is DENIED_ALWAYS, assume it can still be requested (i.e. user selected "Only once" in previous app session)
        if(deviceOS.apiLevel >= 30 && status === diagnostic.permissionStatus.DENIED_ALWAYS && !cameraDeniedAlwaysAfterRequesting){
            status = diagnostic.permissionStatus.DENIED_ONCE;
        }

        switch(status){
            case diagnostic.permissionStatus.GRANTED:
                console.log("Camera permission is allowed")
                break;
            case diagnostic.permissionStatus.NOT_REQUESTED:
                console.log("Camera permission not requested yet - requesting...")
                requestCameraPermission();
                break;
            case diagnostic.permissionStatus.DENIED_ONCE:
                console.log("Camera permission denied but can still request - requesting...")
                requestCameraPermission();
                break;
            case diagnostic.permissionStatus.DENIED_ONCE:
                console.log("Camera permission permanently denied - can't request");
                break;
        }
    }, console.error, diagnostic.permission.CAMERA)
};

function requestCameraPermission(){
    diagnostic.requestRuntimePermission(function(status){

        // If result is DENIED_ALWAYS after requesting then it really is permanently denied
        if(status === diagnostic.permissionStatus.DENIED_ALWAYS){
            cameraDeniedAlwaysAfterRequesting = true;
        }

        // Re-check permission
        checkCameraPermission();

    }, console.error, diagnostic.permission.CAMERA);
}

document.addEventListener("deviceready", onDeviceReady, false);
Runtime permissions example project

While the cordova-diagnostic-plugin-example illustrates use of runtime permissions in the context of requesting location and camera access, the cordova-diagnostic-plugin-android-runtime-example project explicitly illustrates use of Android runtime permissions with this plugin.

Android Camera permissions

Note that the Android variant of requestCameraAuthorization(), in addition to the CAMERA permission, by default also requests storage permissions. This is because the Android camera API requires access to the device's storage to store captured images and videos.

On Android <=12, this requires the WRITE_EXTERNAL_STORAGE and READ_EXTERNAL_STORAGE permissions. On Android >12, this requires the READ_MEDIA_IMAGES and READ_MEDIA_VIDEO permissions.

This is because the cordova-plugin-camera@2.2+ requires both of these permissions.

So to use this method in conjunction with the Cordova camera plugin, make sure you are using the most recent cordova-plugin-camera release: v2.2.0 or above.

iOS usage description messages

When requesting permission to use device functionality, a message is displayed to the user indicating the reason for the request. These messages are stored in the {project}-Info.plist file under NS*UsageDescription keys.

Upon installing this plugin into your project, it will add the following default messages to your plist. To override these defaults, you can use <edit-config> blocks in your config.xml:

config.xml

<platform name="ios">
    <edit-config file="*-Info.plist" target="NSLocationAlwaysUsageDescription" mode="merge">
        <string>My custom message for always using location.</string>
    </edit-config>
    <edit-config file="*-Info.plist" target="NSLocationWhenInUseUsageDescription" mode="merge">
        <string>My custom message for using location when in use.</string>
    </edit-config>
