重新启动后GCMNetworkManager未运行PeriodicTask

Question

如果应用程序在前台,后台运行或被杀死,该应用程序会显示预期的行为.但是,一旦重新启动,PeriodicTask停止运行

以下是相关的代码:

在AndroidManifest:

<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/>
<service android:name=".tracking.MyTaskService"
            android:exported="true"
            android:permission="com.google.android.gms.permission.BIND_NETWORK_TASK_SERVICE">
            <intent-filter>
                <action android:name="com.google.android.gms.gcm.ACTION_TASK_READY" />
            </intent-filter>
        </service>

PeriodicTask配置:

PeriodicTask task = new PeriodicTask.Builder()
                .setService(MyTaskService.class)
                .setTag(TASK_TAG_PERIODIC)
                .setPeriod(30L)
                .setFlex(10L)
                .setExtras(bundle)
                .setPersisted(true)
                .build();

        mGcmNetworkManager.schedule(task);

在Logcat中,我得到以下内容:

E/NetworkScheduler.TED: Couldn't start service: Intent 
{ act=com.google.android.gms.gcm.ACTION_TASK_READY
  cmp=xxx.xxxxxx.xxx/.tracking.MyTaskService (has extras) 
}

附加所有相关细节:

            </intent-filter>
        </activity>

        <!-- [START manifest_service] -->
        <service

            </intent-filter>
        </service>
        <!-- [END manifest_service] -->

    </application>

</manifest>

编辑1:经过几天的分析,我发现了以下几点:

1. 这是特定于设备的问题.例如,在nexus设备上不会发生这种情况.
2. 这是一个更大问题的一部分.显示此行为的设备也无法正常工作AlarmManager,FirebaseJobScheduler和RECEIVE_BOOT_COMPLETED broadcast receiver.
3. 一种解决方法是此解决方案.但是,此解决方案至少有2个问题.(1)当您终止应用程序时,AccessibilityService权限将被重置.这意味着每次在此之后打开应用程序时,都会给出手动权限.(2)如果应用程序被杀死,那么重新启动后就不会命中了RECEIVE_BOOT_COMPLETED broadcast receiver
4. 疯狂的发现:在一加设备中,如果您的应用程序test在包结构中有单词,一切正常!
5. 如果您将应用程序列入白名单设置>应用程序(不同设备的位置和名称可能不同),一切都按预期工作.
6. 您必须手动添加应用程序的启动应用程序包含众所周知的应用程序,如WhatsApp,Facebook,Instagram和许多其他应用程序.当您安装这些应用程序时,它们会自动添加到此列表中!我还没有看到任何这些制造商发布的自定义API来执行此操作.这让我觉得这些应用程序是从制造商的最终列出的白名单.

周期性任务配置：

PeriodicTask task = new PeriodicTask.Builder()
                .setService(MyTaskService.class)
                .setTag(TASK_TAG_PERIODIC)
                .setPeriod(30L)
                .setFlex(10L)
                .setExtras(bundle) **/* you put this line here */**
                .setPersisted(true)
                .build();


    PeriodicTask task = new PeriodicTask.Builder()
                    .setService(MyTaskService.class)
                    .setTag(TASK_TAG_PERIODIC)
/* you don't have ".setExtras(bundle)" line here */ 
/* try adding this line from above, as logcat is showing this */
                    .setPeriod(5)
                    .setPersisted(true)
                    .build();
