我用android studio开发应用程序我有一个连接网页并读取它的服务如果网页包含＆＃34;更新＆＃34;然后程序创建一个Toast消息。服务每3秒钟完成一次。它运作良好但在20-25分钟后服务停止工作我该如何解决呢？

Answer 1

破坏你的服务：

@Override
public void onDestroy() {
    super.onDestroy();
    Intent broadcastIntent = new Intent(".RestartService");
    sendBroadcast(broadcastIntent);
}

在你的清单中添加一个接收器：

        <receiver
            android:name=".ServiceReceiver"
            android:enabled="true"
            android:exported="true"
            android:label="RestartServiceWhenStopped">
        <intent-filter>
            <action android:name=".RestartService"/>
        </intent-filter>
    </receiver>

然后，使用以下代码创建名为ServiceReceiver.java的Java文件：

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;

public class ServiceReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        context.startService(new Intent(context, BackgroundService.class));
    }
}

** BackgroundService是服务类的名称。此代码将帮助您在操作系统或用户关闭服务时自动启动服务。

在你的清单中添加一个接收器：

<receiver android:name="com.example.admin.apptech_nation.service.AlarmManagerBroadcastReceiver"/>

在您的MainActivity中，您需要setRepiting Brodcast

@Override
    protected void onCreate(Bundle savedInstanceState) {
 Intent myIntent = new Intent(mContext, AlarmManagerBroadcastReceiver.class);
    PendingIntent pendingIntent = PendingIntent.getBroadcast(mContext, 0, myIntent, 0);

    AlarmManager alarmManager = (AlarmManager) mContext.getSystemService(Context.ALARM_SERVICE);
    Calendar calendar = Calendar.getInstance();
    calendar.setTimeInMillis(System.currentTimeMillis());
    calendar.add(Calendar.SECOND, 60); // first time
    long frequency = 60 * 50; // in ms
    alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), frequency, pendingIntent); 

}

在你的BroadcastReciver中

public class AlarmManagerBroadcastReceiver extends BroadcastReceiver{
    Context Mcontext;

    @Override
        public void onReceive(Context context, Intent intent) {
            Mcontext = context;

    }
