我正在尝试让设备策略管理器工作,但是当我尝试启用它时,我会陷入困境。谷歌搜索了很多,并已经对这个错误感到愤怒:
10-05 10:39:07.147: WARN/DeviceAdminAdd(144): Unable to retrieve device policy ComponentInfo{test.devadmin/test.devadmin.DeviceAdmin$MyDeviceAdminReceiver}
10-05 10:39:07.147: WARN/DeviceAdminAdd(144): android.content.pm.PackageManager$NameNotFoundException: ComponentInfo{test.devadmin/test.devadmin.DeviceAdmin$MyDeviceAdminReceiver}
清单:

启用方法
public void enable() {
if (!mDPM.isAdminActive(mDeviceAdmin)) {
Intent intent = new Intent(
DevicePolicyManager.ACTION_ADD_DEVICE_ADMIN);
intent.putExtra(DevicePolicyManager.EXTRA_DEVICE_ADMIN,
mDeviceAdmin);
intent.putExtra(DevicePolicyManager.EXTRA_ADD_EXPLANATION,
"Additional text explaining why this needs to be added.");
startActivityForResult(intent, REQUEST_ENABLE);
} else {
mDPM.lockNow();
}
接收者类与此处的基本相同:http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/app/DeviceAdminSample.html

检查您的收件人姓名<receiver android:name="MyDeviceAdminReceiver"
我认为您忘记在收件人姓名之前添加.
:
<receiver android:name=".MyDeviceAdminReceiver"
答案 1 :(得分:3)
我认为如果你重新检查你的DeviceAdmin java文件,你试图扩展的接收者名称与你在android manifest.xml文件中指定的名称不同。只是一个疯狂的猜测,因为你没有显示你的DeviveAdmin java文件
答案 2 :(得分:0)
最后一天,我一直在努力解决这个问题...刚刚遇到了我自己的问题。我的问题出在我的componentName
中
我正在做我的构造函数,例如:
val adminName = ComponentName(this, ::DeviceAdminReceiver.javaClass)
,最后注意到我收到有关公共构造函数的警告 PackageManager.NameNotFoundException ...快速切换到
val adminName = ComponentName("com.project.myApp", "com.project.myApp.DeviceAdminReceiver")
一切都立即生效。
