我在尝试在 android 启动时启动服务时遇到问题,只要手机启动我的应用程序就会出错并且必须停止它。这里是:
我的清单的一部分:
<service
android:name=".EventsNotificationService"
android:label="EventsNotificationService">
<intent-filter>
<action
android:name="it.bloomp.service.EventsNotificationService" />
</intent-filter>
/service>
<receiver
android:name=".receiver.StartEventsNotificationService"
android:enabled="true"
android:exported="true"
android:label="StartEventsNotificationService">
<intent-filter>
<action
android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
我的服务:
package it.bloomp.service;
import android.app.Service;
import android.content.Intent;
import android.os.IBinder;
import android.widget.Toast;
public class EventsNotificationService extends Service {
@Override
public IBinder onBind(Intent intent) {
return null;
}
@Override
public void onCreate() {
super.onCreate();
Toast.makeText(this,"Service created", Toast.LENGTH_LONG).show();
}
@Override
public void onDestroy() {
super.onDestroy();
Toast.makeText(this,"Service destroyed", Toast.LENGTH_LONG).show();
}
@Override
public void onStart(Intent intent, int startId) {
super.onCreate();
Toast.makeText(this,"Service started", Toast.LENGTH_LONG).show();
}
}
我的服务启动器:
package it.bloomp.service;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
public class StartEventsNotificationService extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
if ("android.intent.action.BOOT_COMPLETED".equals(intent.getAction())) {
Intent serviceIntent = new Intent("it.bloomp.service.EventsNotificationService");
context.startService(serviceIntent);
}
}
}
此外,这会使服务在启动时启动,但我怎样才能让它一直运行呢?
