LibGDX And​​roid應用程序在啓動時崩潰

Question

當我運行我的項目時，它立即崩潰並輸出。我創建了一個新的新項目，但它也崩潰了。我使用Eclipse，因爲我非常喜歡它。

編輯：它可以在Android Studio中很好，所以它必須是一些與Eclipse。但如果可能的話，我真的想堅持使用Eclipse。

Answer 1

se.wiklund.memblock.AndroidLauncher未找到類。檢查您的依賴關係/庫作爲日誌警告它不在DexPathList。

而且你應該尋找類似的問題發佈一個前：

Android ClassNotFoundException: Didn't find class on path

我有同樣的問題我project.It發生是由於我的項目，與Android的支持庫版本衝突我在項目中添加的圖書館項目。這裏把同樣版本的Android支持你的項目庫項目包括您圖書館和乾淨的構建......一切都將工作...

Didn't find class on path: dexpathlist

同樣的問題。對我而言，添加android-support-v4.jar作爲lib並確保它已在項目屬性 - >構建路徑 - >訂單&導出上進行檢查。有人提到here

Answer 2

我解決了這個問題，安裝了這個Gradle插件：（http://dist.springsource.com/snapshot/TOOLS/gradle/nightly）。我使用過之前與Eclipse集成的那個。
