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) + "'.";
}
