Question

所以我有BroadcastReceiver注册为：

<receiver
        android:name="package.MyBroadcastReceiver"
        android:enabled="true"
        android:exported="true">
        <intent-filter android:priority="999">
            <action android:name="android.intent.action.USER_PRESENT" />
        </intent-filter>
    </receiver>

我正在使用DevicePolicyManager在用户解锁设备后立即锁定设备 - 因为MyBroadcastReceiver收到广播，请参阅以下代码：

@Override
public void onReceive(final Context context, final Intent intent) {


    deviceManger = (DevicePolicyManager) context.getSystemService(Context.DEVICE_POLICY_SERVICE);
        Runnable runnable = new Runnable() {
            @Override
            public void run() {
                Intent startMain = new Intent(Intent.ACTION_MAIN);
                    startMain.addCategory(Intent.CATEGORY_HOME);
                    startMain.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                    context.startActivity(startMain);

                    deviceManger = (DevicePolicyManager) context.getSystemService(Context.DEVICE_POLICY_SERVICE);
                    //also tried with context..getApplicationContext() but no luck
                    deviceManger.lockNow();
                }
            }
        };

}

所以这段代码工作正常但是当设备断电并重新启动时：

deviceManger = (DevicePolicyManager) context.getApplicationContext().getSystemService(Context.DEVICE_POLICY_SERVICE);
                    deviceManger.lockNow();

上述的编码似乎对设备没有任何影响，即设备不会锁定但是在设备重启之前这种情况正常。我尝试添加日志，我确信代码已执行，但locknow()似乎对设备没有影响......

感谢任何帮助

DevicePolicyManager`lockNow（）;`设备重启后不工作
