Android - 启动时启动服务

Gad*_*ady 96 java android broadcastreceiver intentservice

从我在Stack Exchange和其他地方看到的所有东西,我已经正确设置了所有东西,以便在Android OS启动时启动IntentService.不幸的是它没有启动,我没有收到任何错误.也许专家可以提供帮助......

BroadcastReceiver for Startup:

package com.phx.batterylogger;

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

public class StartupIntentReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        Intent serviceIntent = new Intent(context, BatteryLogger.class);
        context.startService(serviceIntent);
    }
}

更新:我尝试了下面的所有建议,并且我将日志记录添加Log.v("BatteryLogger", "Got to onReceive, about to start service");到StartupIntentReceiver的onReceive处理程序中,并且没有记录任何内容.所以它甚至没有进入BroadcastReceiver.

我想我正在部署APK并正确测试,只需在Eclipse中运行Debug,控制台就说它成功将它安装到我的Xoom平板电脑\ BatteryLogger\bin\BatteryLogger.apk.然后进行测试,我重新启动平板电脑,然后查看DDMS中的日志,并在操作系统设置中检查正在运行的服务.这一切听起来都是正确的,还是我错过了什么?再次,非常感谢任何帮助.

  • +1表示完整示例.也许我应该使用onHandleIntent将我的IntentService更改为普通的旧服务 (9认同)
  • 这最终解决了它.问题是我的服务是IntentService而不是普通的旧服务和服务代码中的错误.这个答案的彻底性和Android中的登录帮助我解决了我的问题. (6认同)
  • 是的,这将没有活动但低于3.1 (6认同)
  • +1详细示例.如果没有活动,这也可以吗? (3认同)
  • onStart() 回调已弃用。您应该使用 onStartCommand() 来代替。 (2认同)
