BitmapTextureAtlasTextureRegionFactory.createFromAsset crash

Question

幾個月前，我看了一下andengine，並且設法做出了一些東西。 現在我下載了最新版本，並且我正在爲最簡單的事情發生崩潰。在這裏我的代碼

（通常它是很好縮進）

的logcat的錯誤是

在AssetBitMapTextureAtlasSource無法載入位圖。資產路徑：GFX/play.png

java.io.FileNoFoundException：GFX/play.png

但我把2個圖像的文件夾中，我加入他們的項目像我一樣，當我第一次嘗試andengine（和它的工作）.. 所以我不真正明白問題所在。

圖片是用gimp（一個是57x36和其他58x31）創建的2 png。

Answer 1

如果找不到文件，則會拋出java.io.FileNoFoundException - 因此除了引擎找不到圖像外，沒有其他可能性。

確保您的圖像位於：assets/gfx/，而不僅僅是在名爲gfx/的文件夾中。

Answer 2

確保有資產的文件夾在您的項目，並從的Buildpath選項（項目選項，你可以在你的項目資源管理器中右鍵單擊訪問），從源選項卡按添加文件夾按鈕，檢查資產文件夾導入編譯過程。

gfx文件夾必須位於資產文件夾中。如果沒有這樣的文件夾和所有圖像是資產文件夾，您不必設置BitmapTextureAtlasTextureRegionFactory.setAssetBasePath("gfx/")

我是新來的android，如果我得到錯誤，我嘗試快速找到正確的可能性。
