我已经阅读了有关Android Oreo背景执行限制的内容,并且明确指出BOOT_COMPLETED广播不会受到影响,但我无法让它在Android Oreo上运行.

首先,我正在编译SDK 27.其次,我在清单文件中声明了接收器:

    <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/>
    <receiver
        android:name="helpers.StartDetectionAtBoot"
        android:label="StartDetectionAtBoot"
        android:enabled="true"
        android:exported="true">
        <intent-filter>
            <category android:name="android.intent.category.DEFAULT"/>

            <action android:name="android.intent.action.MY_PACKAGE_REPLACED"/>

            <action android:name="android.intent.action.BOOT_COMPLETED"/>
            <action android:name="android.intent.action.QUICKBOOT_POWERON"/>
            <!--For HTC devices-->
            <action android:name="com.htc.intent.action.QUICKBOOT_POWERON"/>
            <!--For MIUI devices-->
            <action android:name="android.intent.action.REBOOT"/>
        </intent-filter>
    </receiver>

然后就是接收器的实现,它也可以很简单:

public class StartDetectionAtBoot extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        Log.i("test", "test");

        Intent intent0 = new Intent( context, ActivityRecognitionService.class );
        PendingIntent pendingIntent = PendingIntent.getService(context, 111, intent0, PendingIntent.FLAG_UPDATE_CURRENT);
        ActivityRecognitionClient activityRecognitionClient = ActivityRecognition.getClient(context);
        activityRecognitionClient.requestActivityUpdates(5000, pendingIntent);
    }
}

onReceive 方法未被调用,我将永远在Android Oreo设备/模拟器上获得logcat错误:
