运行意图DevicePolicyManager.ACTION_ADD_DEVICE_ADMIN从服务 [英] Run intent DevicePolicyManager.ACTION_ADD_DEVICE_ADMIN from a service

问题描述

我有一个服务，我要服务促进使其能够为设备管理员，  到现在为止我公司推出这种UI交互从服务像

I have a service and I want the service promote to enable it as Device Admin, until now I launched this kind of UI interactions from the service like

    Intent intent2 = new Intent();
    intent2.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    intent2.setAction(android.content.Intent.ACTION_VIEW);
    intent2.setDataAndType(uri, "application/vnd.android.package-archive");
    context.startActivity(intent2);

和它的工作原理，但与DevicePolicyManager我找不到的方式：

and it works, but with DevicePolicyManager I can't find the way:

        Intent intent = new Intent(DevicePolicyManager.ACTION_ADD_DEVICE_ADMIN);
        intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        intent.putExtra(DevicePolicyManager.EXTRA_DEVICE_ADMIN, mAdminName);
        intent.putExtra(DevicePolicyManager.EXTRA_ADD_EXPLANATION,  "some text.");
        context.startActivity(intent);

简化版，工作方式：不提倡什么，但也不会崩溃。如果没有 intent.setFlags（Intent.FLAG_ACTIVITY_NEW_TASK）; 这只是崩溃，因为这code是一个服务里面的胎面内。想法？

does't work: do not promote nothing but also do not crash. Without intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); It simply crash because this code is inside a tread inside a service. Ideas?

推荐答案

我刚刚固定等问题，为我自己。

I've just fixed such issue for myself.

请注意，你需要把这个code里面父的Andr​​oid Manifest.xml文件：

Note, that you need to put this code inside parent in Android Manifest.xml file:

    <receiver
        android:name=".ScreenLockerDeviceAdminReceiver"
        android:permission="android.permission.BIND_DEVICE_ADMIN" >
        <meta-data
            android:name="android.app.device_admin"
            android:resource="@xml/device_admin_policies" />

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

和它的工作原理：）
