错误产生的原因：android.app.SuperNotCalledException：

我有一个FTP客户端发送正常的文件，但是当我按下菜单，或在手机上通话，它不会在后台发送和关闭应用程序。这是正常的吗？我发送一个文件，当你几乎完成时，有人打电话给我，并清除我的上传，我应该重新开始？错误产生的原因：android.app.SuperNotCalledException：

谢谢。

安置自己的Logacat.Asü标题这个问题华南简介错误发生，但ü没有定义的情况时，发生错误。请更多地解释你的问题。 –

你有没有'onPause'或'OnResume'等你叫'super.pause（）'或'super.onResume'？ –

请仔细检查你的生命周期方法。 –

enviarSegundoPlano = new AsyncTask<Void, Void, Void>(){ 
    @Override 
    protected Void doInBackground(Void... params) { 
     if(arquivo!=null) 
     nomeArquivo = arquivo.getName(); 
     else{ 
     Log.d("LOG_APP", "arquivo null"); 
     // ... 
     } 
     return null; 
    } 
}; 
enviarSegundoPlano.execute();

处理这种情况时arkuivo为空
