报错如下：
Error:Failed to run command:
D:\Program Files\Android\android-sdk\build-tools\20.0.0\aapt.exe s -i C:\Users\Administrator\AndroidstudioProjects\EBook21\app\src\main\res\drawable-hdpi\start.png -o C:\Users\Administrator\AndroidstudioProjects\EBook21\app\build\intermediates\res\release\drawable-hdpi-v4\start.png
Error Code:

Output:

:app:mergeReleaseResources FAILED
Error:Execution failed for task ':app:mergeReleaseResources'.

Error: Failed to run command:
D:\Program Files\Android\android-sdk\build-tools\20.0.0\aapt.exe s -i C:\Users\Administrator\AndroidstudioProjects\EBook21\app\src\main\res\drawable-hdpi\start.png -o C:\Users\Administrator\AndroidstudioProjects\EBook21\app\build\intermediates\res\release\drawable-hdpi-v4\start.png
Error Code:

是什么意思？我删掉build文件夹，重新发布，依旧报这个错
哪位大神好心指导一下。。。

你的start.png文件实际上不是png文件，你不是直接改的后缀名吧？
