使用Parse.com登錄Facebook時NoClassDefFoundError

我目前使用parse.com作爲我的Android應用程序的後端解決方案。我正在嘗試使用Facebook對用戶進行身份驗證，而我目前正在遇到以下錯誤。我試圖將JARS（Parse和Facebook）添加到我的項目中。我也已經打掃我的項目好幾次，但我仍然得到以下錯誤：使用Parse.com登錄Facebook時NoClassDefFoundError

在'/ libs'文件夾中的罐子解決方案？ – 2013-03-03 15:06:14

試試[this]（http://stackoverflow.com/questions/13964392/im-getting-a-java-lang-classnotfoundexception-com-mysql-jdbc-driver/13964418#13964418）。另外該jar應該在libs文件夾中，就像Raghav已經提到的一樣:) – Ahmad 2013-03-03 15:08:13

@RaghavSood解析jar和facebook android支持jar都在libs文件夾中，我仍然得到相同的錯誤。 – AndroidEnthusiast 2013-03-03 15:17:22

確保你檢查的複選框在Java Build Path - >Order and Export -tab。

我已經做到了。 – AndroidEnthusiast 2013-03-03 15:18:26

我得到改變我的minSdkVersion（11比8）
