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-------------");
        }
    }
}
