静态注册实现开机启动

新建广播接收器（在动态监听基础上加的）

修改广播接收器代码

public class BootCompleteReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        // TODO: This method is called when the BroadcastReceiver is receiving
        // an Intent broadcast.
        Toast.makeText(context, "Boot Complete", Toast.LENGTH_SHORT).show();
    }
}

manifest
