在Android上的Twitter上發佈後應用程序退出？

Question

我正在研究一個基本的Android應用程序，在這個應用程序中，我在Twitter上發佈了一個小文本字符串。 問題是，在twitter上發佈我的應用程序退出後。我在之前的應用程序中使用了相同的代碼，但現在它不能正常工作。請讓我知道我在做什麼錯誤。

下面的代碼是PrepareRequestTokenActivity.java

/** 
* Prepares a OAuthConsumer and OAuthProvider 
* 
* OAuthConsumer is configured with the consumer key & consumer secret. 
* OAuthProvider is configured with the 3 OAuth endpoints. 
* 
* Execute the OAuthRequestTokenTask to retrieve the request, and authorize the request. 
* 
* After the request is authorized, a callback is made here. 
*

public class PrepareRequestTokenActivity extends Activity {

     } catch (Exception e) {

       Toast.makeText(PrepareRequestTokenActivity.this, "Message posted successfully", Toast.LENGTH_LONG).show(); 
      } 
     } 
    }; 

}

我解決了這個問題，但它只是一個用於這個時候，我取消註釋調用從中我是來嘰嘰喳喳

後面活動的代碼

context.startActivity(new Intent(context,WeddingRituals.class));
