android开机起动一个Service实例

android开机启动一个Service研究一下其实也蛮简单，下面直接看代码吧。

package com.test.kevin;import android.content.BroadcastReceiver;import android.content.Context;import android.content.Intent;import android.util.Log;public class BootBroadcastReveiver extends BroadcastReceiver {	private static final String TAG = "BootBroadcastReveiver";	@Override	public void onReceive(Context context, Intent intent) {		if (intent.getAction().equals(Intent.ACTION_BOOT_COMPLETED)) {			Intent bootServiceIntent = new Intent(context, MainActivity.class);			context.startService(bootServiceIntent);			Log.d(TAG, "--------Boot start service-------------");		}	}}

?? 把以上代码一个小小Service实例，重启机子后可以直接远行.
