Question

我正在尝试向我的应用添加一个按钮，将其从设备管理员中删除，并使用下面的代码，但我的应用只是崩溃。

代码： -

按钮单击： -

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

在上面的代码中，DemoDeviceAdminReceiver是一个扩展DeviceAdminReceiver的类。

错误日志： -

Answer 1

就像你一样：

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

但您需要在AndroidManifest.xml中将这些过滤器添加到接收器：

    <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) + "'.";
}

Android：以编程方式从设备管理员中删除我的应用？
