我最近将所有服务替换为前台服务和JobIntentService，因为在oreo及更高版本中存在一些后台执行限制(https://developer.android.com/about/versions/oreo/background)。根据文档，JobIntentService的行为类似于适用于Android 7及更高版本的Intent Service，行为类似于JobScheduler(适用于Android 8及更高版本)。我注意到Google提供的新JobIntentService中存在问题。

Android 8及更高版本:

在Android 8及更高版本中不断发生崩溃。这里有一张票提到了同样的问题https://issuetracker.google.com/issues/63622293，我添加了一些极客建议的临时修复程序。

Android 7及以下版本:
一旦工作完成，充当Intent Service的JobIntentService不会停止。

我已经在服务中实现JobIntentService，只要用户执行某些操作，该服务就会触发。

代码

public class SampleJobIntentService extends FixedJobIntentService {

public static void postData(Context context, String data) {
    Intent intent = new Intent(context, SampleJobIntentService.class);
            intent.setAction(INITIAL_ACTION);
            intent.putExtra(SAMPLE_ID, data);
            SampleJobIntentService.enqueueWork(context,intent);
}

public static void enqueueWork(Context context, Intent work) {
    SampleJobIntentService.enqueueWork(context, SampleJobIntentService.class, JOB_ID, work);

 @Override
    protected void onHandleWork(@NonNull Intent intent) {
        if (intent != null) {
            SampleRequest sampleRequest = requests.get(intent.getAction());
            if (sampleRequest != null) {
                try {
                   // perform some networking operations
                } catch (Exception ex) {
                    Log.d("Error for intent ");
                }
                Log.i("send action ");
            } else
                Log.e("action not found for ");
        }
    }
    }

public abstract class FixedJobIntentService extends JobIntentService {

    @Override
    GenericWorkItem dequeueWork() {
        try {
            return new FixedGenericWorkItem(super.dequeueWork());
        } catch (SecurityException ignored) {
            doStopCurrentWork();
        }
        return null;
    }

    private class FixedGenericWorkItem implements GenericWorkItem {
        final GenericWorkItem mGenericWorkItem;

        FixedGenericWorkItem(GenericWorkItem genericWorkItem) {
            mGenericWorkItem = genericWorkItem;
        }

        @Override
        public Intent getIntent() {
            if (mGenericWorkItem != null) {
                return mGenericWorkItem.getIntent();
            }
            return null;
        }

        @Override
        public void complete() {
            try {
                if (mGenericWorkItem != null) {
                    mGenericWorkItem.complete();
                }
            } catch (IllegalArgumentException ignored) {
                doStopCurrentWork();
            }
        }
    }
}

最佳答案

Well..., Its a lot big theory...!! It would not be able to put it all here. I will try my best which will make some your concepts clear.

YOU :- I have recently replaced all my service to foreground services and JobIntentService

YOU :- I have recently replaced all my service to foreground services and JobIntentService

Correct me ... too... As you have not mentioned what your tasks and project is related to... and what you exactly wants to be done in a foreground service and intent-service... Let me know..., It would be my pleasure to help you. It is a general theoretical answer rather than what you wants.... But for giving you actual answer i will need exact your project scope..

关于Android Oreo JobIntentService继续在Android 7及以下版本的后台运行，并在Android 8及更高版本中经常崩溃，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/51627968/
