我正在创建一个RestartServiceBroadcast,以在终止应用程序后始终保持我的后台服务正常运行。
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同一服务。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>
ipManager类,用于获取广播的值
public final class ipManager {
public static final String INTENT_SIP_SERVICE_RESTART = "demo.magic.mobile.service.RestartService";
}
我的motoG5和MI Note5 Pro设备中的所有代码都能正常工作。但在MI note4和MI4设备中,从后台删除该应用程序后,该服务和广播已被终止。
MotoG5和其他设备Logcat当我杀死应用程序时,就像这样。

感谢您的帮助,在此先感谢。
最佳答案
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);
}
关于android - 内存终止或销毁 Activity 时,Service和BroadcastReceiver在MI电话中不起作用,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/55847610/
