我在這裏以下指南：https://www.parse.com/docs/android_guide#ui-login如何在Android上導入ParseLoginUI？
我已經下載了ParseLoginUI庫在這裏：https://github.com/ParsePlatform/ParseUI-Android
我加入以下代碼到我的AndroidManifest.xml：
<activity
android:name="com.parse.ui.ParseLoginActivity"
android:label="@string/app_name"
android:launchMode="singleTop">
<meta-data
android:name="com.parse.ui.ParseLoginActivity.PARSE_LOGIN_ENABLED"
android:value="true"/>
</activity>
爲了事業編譯器（Android Studio）識別com.parse.ui.ParseLoginActivity我已去file>import module並選擇了ParseLoginUI模塊，添加了必要的Version 21 Android庫，並重新啓動了該項目。
Android Studio仍然無法爲com.parse.ui.ParseLoginActivity「查看」ParseLoginUI。
如果我去Open Module Settings>Dependencies並添加它，我得到運行以下dexDebug錯誤（具有我認爲同樣的事情重新定義，因爲我已經進口螺栓和底座解析庫）：
錯誤：執行失敗的任務'：app：dexDebug'。
