They say您不需要NFC也不需要生根来实现应用程序成为device owner.我还没有看到这个方法的完整示例但是让我们试试：

adb shell dpm set-device-owner <package>/.<ReceiverImplementation>

应该这样做…所以我这样做,并得到：

java.lang.SecurityException: 
Neither user 2000 nor current process has android.permission.BIND_DEVICE_ADMIN.

因此,以下代码返回false.

((DevicePolicyManager) getSystemService(Context.DEVICE_POLICY_SERVICE))
   .isDeviceOwnerApp(getApplicationContext().getPackageName())

This STO question提出了类似的问题,但未指明实际的失败.

清单文件和源代码的其余部分主要来自this google sample

<manifest
    package="com.example.android.deviceowner"
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:versionCode="1"
    android:versionName="1.0">
 
    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme">
 
        <activity
            android:name=".MainActivity"
            android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN"/>
                <category android:name="android.intent.category.LAUNCHER"/>
            </intent-filter>
        </activity>
 
        <receiver
            android:name=".DeviceOwnerReceiver"
            android:description="@string/app_name"
            android:label="@string/app_name"
            android:permission="android.permission.BIND_DEVICE_ADMIN">
            <Meta-data
                android:name="android.app.device_admin"
                android:resource="@xml/device_owner_receiver"/>
            <intent-filter>
                <action android:name="android.app.action.ACTION_DEVICE_ADMIN_ENABLED"/>
            </intent-filter>
        </receiver>
 
    </application>
 
</manifest>

我试图这样做的设备目前是LG G Pad.
