How to read selected mock location app in Android M - API 23

Question

I am trying to find a way of reading the new settings for mock locations in Android M.

Before Android M, the mock location setting was a toggle option called "use mock locations", and it was readable with this setting: Settings.Secure.ALLOW_MOCK_LOCATION

With Android M, the mock location setting is an app to select for mock locations, so it is a multi-elements list, which selected element can be "none".

That thread has a solution for determining the source of the location update when listening for locations, but unfortunately I would like to read the setting itself: How to check for Mock Location in Android Marshmallow?

I would like to read whether there is a selected app for mock locations or not, and ideally the selected app as well. Any idea about how to do that are welcome!

Ok digging through the android developer site this is what I have come up with. You have to use the AppOpsManager. checkOp("android:mock_location", "yourUID", "com.your.package.name")

I think you can check if a different app is enabled by changing the package name.

public boolean isMockLocationEnabled(){
    boolean isMockLocation = false;
    try {
        //if marshmallow
        if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
            AppOpsManager opsManager = (AppOpsManager) mContext.getSystemService(Context.APP_OPS_SERVICE);
            isMockLocation = (opsManager.checkOp(AppOpsManager.OPSTR_MOCK_LOCATION, android.os.Process.myUid(), BuildConfig.APPLICATION_ID)== AppOpsManager.MODE_ALLOWED);
        } else {
            // in marshmallow this will always return true
            isMockLocation = !android.provider.Settings.Secure.getString(mContext.getContentResolver(), "mock_location").equals("0");
        }
    } catch (Exception e) {
        return isMockLocation;
    }
    return isMockLocation;
}

For those attempting to do this using ADB, here are the commands for getting and setting the mock app:

Allowing app for mock locaiton

adb shell appops set <PACKAGE> android:mock_location allow

Removing app for mock location

adb shell appops set <PACKAGE> android:mock_location deny

Checking if app is set for mock location

adb shell appops get <PACKAGE> android:mock_location
