當我單擊此按鈕時，錯誤在這里

twitterbutton.setOnClickListener(new OnClickListener() {

            @Override

                String token = "" + accessToken;
                //Toast.makeText(getApplicationContext(), token, 500).show();
            }
        });

當我單擊此按鈕時，它強制關閉，這是日志貓

請注意，此代碼在沒有Facebook的其他項目中也可以使用

問題是當我單擊Twitter按鈕時，它強制關閉

Answer 1

我有同樣的問題..幾天后我發現了問題：

<activity
        android:name=".TwitterLoginActivity"
        android:label="@string/app_name"
        android:screenOrientation="portrait"
        android:noHistory="true" >
</activity>

noHistory =“ true”導致Twitter登錄后強制關閉
