不幸的是，AppName在點擊按鈕後已停止

我在Edittext中登錄並輸入消息。但是當我點擊發送按鈕時，應用程序顯示Webview彈出窗口大約幾分鐘後才顯示消息「不幸的是，AppName已停止」。像在Facebook網頁視圖登錄彈出不幸的是，AppName在點擊按鈕後已停止

的WebView彈出

MainActivity.java

public class MainActivity extends Activity { 

public static Facebook facebook = new Facebook("apikey"); 
AsyncFacebookRunner mAsyncRunner = new AsyncFacebookRunner(facebook); 
String token; 
Button login; 
Button send; 
EditText msg; 
TextView onoff; 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.postapp); 
    login = (Button)findViewById(R.id.login); 
    send = (Button)findViewById(R.id.send); 
    msg = (EditText)findViewById(R.id.msg); 
    onoff = (TextView)findViewById(R.id.onoff); 
    login.setOnClickListener(new OnClickListener() 
    { 
     public void onClick(View v) { 
      facebook.authorize(MainActivity.this, new String[]{"publish_stream"}, new DialogListener(){ 

       @Override 
       public void onComplete(Bundle values) { 
        onoff.setText("On"); 
        token =values.getString(Facebook.TOKEN); 
       } 

       @Override 
       public void onFacebookError(FacebookError e) { 
        Log.d("FACEBOOK ERROR","FB ERROR. MSG: "+e.getMessage()+", CAUSE: "+e.getCause()); 
       } 

       @Override 
       public void onError(DialogError e) { 
        Log.e("ERROR","AUTH ERROR. MSG: "+e.getMessage()+", CAUSE: "+e.getCause()); 
       } 

       @Override 
       public void onCancel() { 
        Log.d("CANCELLED","AUTH CANCELLED"); 
       } 
      }); 

     } 
    }); 

    send.setOnClickListener(new OnClickListener(){ 
     public void onClick(View v) { 
      updateStatus(token); 
     } 
    }); 
} 

public void updateStatus(String accessToken){ 
    try { 
     Bundle bundle = new Bundle(); 
     bundle.putString("message",msg.getText().toString()); 
     bundle.putString(Facebook.TOKEN,accessToken); 
     String response = facebook.request("me/feed",bundle,"POST"); 
     Log.d("UPDATE RESPONSE",""+response); 
    } catch (MalformedURLException e) { 
     Log.e("MALFORMED URL",""+e.getMessage()); 
    } catch (IOException e) { 
     Log.e("IOEX",""+e.getMessage()); 
    } 
} 
}

和postapp.xml

<?xml version="1.0" encoding="utf-8"?>

android:layout_width="match_parent" 
android:layout_height="match_parent"

     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:text="Sign-in" /> 

    <TextView 
     android:id="@+id/onoff" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:text="off" 
     android:textAppearance="?android:attr/textAppearanceLarge" /> 

</LinearLayout> 

<LinearLayout 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" > 

    <EditText 
     android:id="@+id/msg" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_weight="1" 
     android:ems="10" /> 

    <Button 
     android:id="@+id/send" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_weight="1" 
     android:text="Send" /> 
</LinearLayout>

它沒有停止沒有理由...閱讀logcat日誌 – Selvin

什麼是logcat說？你的webview代碼是什麼？ – codeMagic

您正在嘗試在當前代碼中對主UI線程執行網絡操作。所以要避免應用的UI和崩潰的懸掛實現使用AsyncTask

把所有的Facebook網絡運行代碼中doInBackground和更新內部的AsyncTaskonPostExecute UI的東西，以避免所有代碼代碼「不幸的是，AppName的已停止。」消息

您可以將這些代碼之前授權方法

StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build(); 
StrictMode.setThreadPolicy(policy);

Thx非常感謝您的幫助 –

試試你的應用超越了蜂巢。它不會在低於3.0的較低版本中顯示此異常在2.2或2.3上嘗試它會起作用。 This將對您有所幫助。
