Android: Programmatically remove my app from Device Administrator?

Question

I'm trying to add a button to my app to remove it from Device Administrator and am using the code below but my app just crashes.

Code:-

On Button Click:-

{
    ComponentName devAdminReceiver = new ComponentName(this, DemoDeviceAdminReceiver.class);
    DevicePolicyManager dpm = (DevicePolicyManager) getSystemService(Context.DEVICE_POLICY_SERVICE);
    dpm.removeActiveAdmin(devAdminReceiver);
}

In the code above, DemoDeviceAdminReceiver is a class that extends DeviceAdminReceiver.

Error log:-

It's as you do:

DevicePolicyManager mDPM = (DevicePolicyManager)getSystemService(Context.DEVICE_POLICY_SERVICE);
mDPM.removeActiveAdmin(mDeviceAdminReceiver);

But you need to add these filters to the receiver in AndroidManifest.xml:

    <intent-filter>
        <action android:name="android.app.action.DEVICE_ADMIN_ENABLED" />
        <action android:name="android.app.action.DEVICE_ADMIN_DISABLED" />
    </intent-filter>


@Override
public CharSequence onDisableRequested(Context context, Intent intent) {
    return "Admin rights are beeing requested to be disabled for the app called: '" + context.getString(R.string.app_name) + "'.";
}

Thanks for the fast response. The intent filters are already present in the AndroidManifest.xml file. Device administrator is enabled just fine but trying to remove is still causing the crash. – Jasjit Singh Marwah Oct 28 '12 at 12:20
Oh, fixed it. The issue was with the DeviceAdminReceiver class. I was using a separate class to enable device admin but when I tried to remove it I was using a different DeviceAdminReceiver which was not even enabled as device admin. Silly me. Thanks for your help. – Jasjit Singh Marwah Oct 28 '12 at 12:25
@ViliusK can we disable device administrator permission of other app if my app has device admin permission ? – rupesh Oct 06 '15 at 06:43
