無法解決錯誤 - java.lang.NoClassDefFoundError：com.google.android.gms.R $字符串

我已經在StackOverflow中看到這個問題，但剛剛提到的解決方案導入谷歌播放服務。我做到了，但仍然沒有這個錯誤，我的應用程序在開始時崩潰。我想使用谷歌地圖，並已獲得API密鑰，並將其放入應用程序。正如我所說，我已經導入了谷歌播放服務，但事情不起作用，應用程序崩潰在我的手機上運行它。我的堆棧跟蹤是 - ：

嘗試建立和清潔？ – CynePhoba12

是的，我也試過這個，但它沒有工作 –

另外我有一個混亂的意思是在Android工作室添加項目，我只是使用導入.jar文件 –

您需要在Android Studio中添加build.gradle中的依賴項。

dependencies { 
    compile fileTree(dir: 'libs', include: ['*.jar']) 
    compile 'com.google.android.gms:play-services:8.1.0' 
}

也同步，那麼你的分類應該被添加。 –

很明顯，我做到了這一點 –
