我正在尝试添加一个按钮到我的应用程序从设备管理器中删除它,并使用下面的代码,但我的应用程序只是崩溃.
码：-
按钮点击： –
{
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是扩展DeviceAdminReceiver的类.
错误日志： –

解决方法
就像你一样：
DevicePolicyManager mDPM = (DevicePolicyManager)getSystemService(Context.DEVICE_POLICY_SERVICE); mDPM.removeActiveAdmin(mDeviceAdminReceiver);
但是您需要在AndroidManifest.xml中的接收器中添加这些过滤器：
<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) + "'.";
}
