内存终止或销毁活动时,Service和BroadcastReceiver在MI电话中不起作用

我正在创建一个RestartServiceBroadcast,以在杀死应用程序后使我的后台服务始终保持活动状态。

  public class RestartServiceBroadcast extends BroadcastReceiver {

                Context ctx;
                private PreferencesProviderWrapper prefProviderWrapper;

                @Override
                public void onReceive(Context context, Intent intent) {
                    this.ctx= context;
                    System.out.println("RestartServiceBroadcast:");
                    if(intent.getAction().equals(ipManager.INTENT_SERVICE_RESTART)){
                        startOneService();
                    }

                }

                private void startOneService() {


            }
                }

在这里,我还创建了一项服务来连接服务器IP。在该服务中,我还触发了广播以重新启动相同的服务。我也在服务中使用START_STICKEY

public class IpService extends Service {

@Override
    public void onCreate() {
        super.onCreate();

    }

@Override
    public void onDestroy() {
        super.onDestroy();
        System.out.println("ipStack : onDestroy");

        Intent broadcastIntent = new Intent(ipManager.INTENT_SERVICE_RESTART);
        sendBroadcast(broadcastIntent);
    }
}

我正在mainActivity onDestroy()方法中调用Broadcast。

 override fun onDestroy() {
           val broadcastIntent = Intent(ipManager.INTENT_SERVICE_RESTART)
            sendBroadcast(broadcastIntent)
            super.onDestroy()
        }

这是我的清单

 <service
            android:name=".service.ipService"
            android:enabled="true"
            android:exported="false"
            android:permission="demo.magic.mobile.android.permission.CONFIGURE_IP"
            android:process=":ipStack"
            android:stopWithTask="false">
            <intent-filter>
                <action android:name="demo.magic.mobile.service.ipService" />
                <action android:name="demo.magic.mobile.service.ipConfiguration" />
            </intent-filter>
        </service>




        <receiver
            android:enabled="true"
            android:exported="true"
            android:name=".service.receiver.RestartServiceBroadcast"
            android:process=":ipStack">
            <intent-filter>
                    <action android:name="demo.magic.mobile.service.RestartService" />
            </intent-filter>
        </receiver>

用于获取广播值的ipManager类

public final class ipManager {

    public static final String INTENT_SIP_SERVICE_RESTART = "demo.magic.mobile.service.RestartService";
}

所有代码在我的motoG5和MI Note5 Pro设备中均能正常工作。但在MI note4和MI4设备中,从后台删除该应用程序后,服务和广播已被终止。

MotoG5和其他设备Logcat在杀死应用程序时像这样。

2019-04-25 15:27:00.220 2345-3735/? W/ActivityManager: Scheduling restart of crashed service demo.magic.mobile/.service.ipService in 20942ms

2019-04-25 15:27:21.490 23954-23954/demo.magic.mobile:ipStack I/System.out: ipStack : onstart 

MI Note4的Logcat杀死应用程序进程

我们将不胜感激,谢谢您。

在服务类别中使用此方法

@Override 
    public void onTaskRemoved(Intent rootIntent){
        Intent broadcastIntent = new Intent(ipManager.INTENT_SERVICE_RESTART);
        sendBroadcast(broadcastIntent);
    }

最后,我得到了一个完美的解决方案。我正在使用氧气,色彩和miui等所有操作系统在oreo中进行测试。我正在开发VoIP应用程序,并且在应用程序被用户破坏或杀死后,一个sip服务正在继续运行。用户设置应用程序还有另外一件事,那就是始终在手机设置中运行后台和电池优化。

我正在使用Alarm Manager来使我的服务保持活动状态,它比作业计划程序再呼叫服务更好。我在服务类的oncreate()方法中实现了此代码。

 public class CallService extends Service {

            @Override
            public void onCreate() {
                super.onCreate();
                Intent intent = new Intent(this, RestartServiceBroadcast.class);
                mKeepAlivePendingIntent = PendingIntent.getBroadcast(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
                ((AlarmManager) this.getSystemService(Context.ALARM_SERVICE)).setRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP, SystemClock.elapsedRealtime() + 60000, 60000, mKeepAlivePendingIntent);
            }

        }

创建一个BroadcastReceiver以在用户从内存任务中杀死应用程序时再次调用服务

public class RestartServiceBroadcast extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        if (intent.getAction().equals("service.RestartService")) {
        // Here Call a Service
    }

    }
}

像这样

<receiver
                android:name=".service.receiver.RestartServiceBroadcast"
                android:enabled="true"
                android:exported="true"
                android:process=":sipStack">
                <intent-filter>
                    <action android:name="service.RestartService" />
                </intent-filter>
   </receiver>

        <service
            android:name=".service.CallService"
            android:enabled="true"
            android:exported="false"
            android:stopWithTask="false">

        </service>
