我的代碼PhysicsRemoveExample.java（AndEngine）有什麼問題？

試圖從here製作示例PhysicsRemoveExample.java。我的代碼PhysicsRemoveExample.java（AndEngine）有什麼問題？

我得到這個消息在程序啓動時：

Sorry! The application PhysicsRemoveExample(process org.anddev.andengine.PhysicsRemoveExample) has stopped unexpectedly. Please try again.

我構建路徑andengine.jar和andenginephysicsbox2dextension.jar assets/gfx -> face_box_tiled.png和face_circle_tiled.png。

這是我的Java代碼PhysicsRemoveExample.java。與示例中相同，但我已更改爲extends BaseGameActivity。

有什麼不對？已經嘗試過仿真器1.6和2.1，並創建了一個全新的AVD。我可以做Getting Started Tutorial (Video – 5 minutes)沒有任何問題。

剛剛從andengine例子項目複製「庫」文件 - 而不是在「LIB」文件 - 並將其粘貼到您的項目。

這是我做過什麼，以獲得物理學在Eclipse工作:::

1. 運行和安裝：水銀-2.1.exe

善變-2.1給你HG命令工具。
在命令（DOS）提示符下使用hg工具來獲取最新的AndEngine 和andenginephysicsbox2dextension。使用下面的命令汞柱>

汞柱克隆https://code.google.com/p/andenginephysicsbox2dextension/

汞柱克隆https://andengine.googlecode.com/hg/ andengine

這將下載的兩個項目。將它們導入Eclipse。使用FILE - >導入 - >現有項目進入工作區 - >選擇根目錄 - >瀏覽查找使用hg命令下載的AndEngine項目。對andenginephysicsbox2dextension項目執行相同操作 - 因此您將在Eclipse中擁有兩個庫項目。
您可能需要右鍵單擊該項目並將「Project Build target」設置爲 Android 2.3。您可能還需要在項目的根目錄中創建res和gen文件夾。確保項目已編譯完成。
右鍵單擊項目並選擇導出 - >在Java下選擇「jar文件」選項。點擊下一步。在右側窗格中顯示UNTICK所有內容 - AndroidManifest的位置。xml和其他所有其他列表取消選中它。例如，如果您正在編譯AndEngine.jar ，則可以在jar文件輸入框中輸入：C：\ temp \ andengine.jar 指定.jar文件的位置。點擊完成 - 它應該編譯。
轉到這個網站：

http://code.google.com/p/andenginephysicsbox2dextension/source/browse/libs/?name=ed03082d4a&r=38406ae958c5f5ed89e2e73e9e71385c242e8e28#libs%2Farmeabi-v7a%253Fstate%253Dclosed

下載兩個文件。所以這些都需要進入： armeabi armeabi-V7A

具備.jar文件進入根目錄下的lib文件夾。 .so文件---在根目錄下創建一個名爲libs的文件夾。在libs文件夾下創建兩個文件夾armeabi和armeabi-v7a - .so文件進入這兩個文件夾。

但複製後，此lib文件應用程序將不會啓動。應用程序已啓動但未關閉，無任 – 2012-03-23 12:29:12

谷歌代碼存儲庫現已過時，AndEngine和所有擴展都位於GitHub上：https：//github.com/nicolasgramlich/ – JohnEye 2012-05-18 12:38:44

And old andengine.jar andenginephysicsbox2dextension.jar remvove。

我面臨同樣的問題，是無法對發生此問題做任何事情。一次又一次。

啊，最後我能解決的問題，並希望分享，因爲必須有可能whop必須有毛:)

的寬鬆tonns我只需更換一個從薩科回購協議回購RealMayo。以下是鏈接 https://github.com/RealMayo/AndEnginePhysicsBox2DExtension。

請讓我知道。 :)
