Android GCM - WakefulBroadcastReceiver.startWakefulService 由于 IllegalStateException 8.0 而崩溃

Question

我们刚刚将应用程序的目标 api 迁移到 Android API 27 (8.1)，当通知到达时它一直崩溃，特别是当应用程序在后台时。

我是这样解决问题的：

为什么会出现这个问题？

Due to the new Background Execution Limits of Android 8 and you should not start services background.

我是如何修复的

将您的 GCMIntetService 迁移到 JobIntentService 而不是 IntentService。

请按照以下步骤操作： 1) 为您的服务添加BIND_JOB_SERVICE权限：

<service android:name=".service.GCMIntentService"
        android:exported="false"
        android:permission="android.permission.BIND_JOB_SERVICE"/>

2) 在您的 GCMIntentService 中，而不是扩展 IntentService，使用 android.support.v4.app.JobIntentService 并覆盖 onHandleWork 然后删除 onHandleIntent.

中的 override

public class GCMIntentService extends JobIntentService {

    // Service unique ID
    static final int SERVICE_JOB_ID = 50;

    // Enqueuing work in to this service.
    public static void enqueueWork(Context context, Intent work) {
        enqueueWork(context, GCMIntentService.class, SERVICE_JOB_ID, work);
    }

    @Override
    protected void onHandleWork(@NonNull Intent intent) {
        onHandleIntent(intent);
    }

    private void onHandleIntent(Intent intent) {
        //Handling of notification goes here
    }
}

最后，在您的 GCMBroadcastReceiver 中，将您的 GCMIntentService 加入队列。

public class GCMBroadcastReceiver extends WakefulBroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        // Explicitly specify that GcmIntentService will handle the intent.
        ComponentName comp = new ComponentName(context.getPackageName(),
                GCMIntentService.class.getName());
        // Start the service, keeping the device awake while it is launching.
        // startWakefulService(context, (intent.setComponent(comp)));

        //setResultCode(Activity.RESULT_OK);

        GCMIntentService.enqueueWork(context, (intent.setComponent(comp)));
    }
}

在我们将目标 sdk 更新到 27 后，这个实现对我有用，我希望它对你有用。
