.apk上傳成功，但在ClassNotFoundException中啓動意圖結果com.game.demo.helloworld

我使用Cocos2dx庫設置Eclipse IDE。我試圖在cocos2dx庫中設置並運行helloworld項目，但是在helloworld.apk成功上傳到模擬器後，我在LogCat中遇到此錯誤。.apk上傳成功，但在ClassNotFoundException中啓動意圖結果com.game.demo.helloworld

我在SDK 17 Eclipse構建：v22.0.1-685705

我已經通過計算器上幾乎4-5類似的帖子看了，但已經嘗試一切，不知道如何解決這個問題。

這裏的logcat的條目：

這裏是我的AndroidManifest.xml文件：

郵政helloworld.java（一個開始'package'）在helloworld.java –

第一行是第一行：包com.game.demo.helloworld;這與AndroidManifest.xml中的android：name標籤值相匹配。但我認爲我只是錯誤地引用了軟件包？讓我更新該項目的屏幕截圖...也許這將有助於... – user2518312

我沒有足夠的分數來添加屏幕截圖。 – user2518312

我剛做了一個類似的錯誤，昨天還沒有與上所提供的所有答案的成功。我終於找到了：

我在代碼中的任何地方都使用了「ViewPager」。

但是，在使用過的.xml文件中，我偶然輸入了「viewPager」 - 當然那個找不到。

另外，正如我今天發現的那樣，如果有的話，請仔細檢查您在.xml中使用的對象的包名。

你用apk輸出了cocos2dx jar嗎？如果不是這樣，它會編譯，但會崩潰。

您的清單包被聲明爲com.game.demo，但您的文件位於com.game.demo.helloworld。

嘗試：

<activity android:name="com.game.demo.helloworld.helloworld"
