Android 实现监听开机启动开启后台服务，并实现自动重启。

1.创建广播监听器，继承BroadcastReceiver

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

public class BootBroadcastReceiver extends BroadcastReceiver {

static final String ACTION = "android.intent.action.BOOT_COMPLETED";

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

if (intent.getAction().equals(ACTION)) {
Intent service = new Intent(context, BootService.class);
context.startService(service);
}
}
}

2.在AndroidManifest.xml中注册广播接收器，并设置action为android.intent.action.BOOT_COMPLETED，这样项目就能监听开机事件。

 

<receiver android:name="com.huahu.bootstart.BootBroadcastReceiver" >
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>

3.创建BootService服务，重写onStartCommand方法，设置flags，这样当服务关闭时，能够自动重启服务。

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
flags = START_STICKY;
return super.onStartCommand(intent, flags, startId);
}
