相信你们可能和我一样都是一脸的懵逼，，说真我也不知道具体的是什么？出现这样的异常因为反射目标没有指定，对于API越高的，对于用户的安全要求和机制越来越严格，如果不知道某一反射的包名，机会出现异常。

下面说说解决的方案：只需要在代码中加入这一行代码： 

intent.setPackage("指定的包名");
例如：

public void bingService(View view){
    Log.i(TAG,"触发了绑定服务的方法");
    Intent intent = new Intent("com.example.roveservice");
    //intent.setPackage("com.example.roveservice");
    conn = new MyConn();
    bindService(intent,conn,BIND_AUTO_CREATE);
}
轻松解决此异常。
