libpng error: Not a PNG file
Android Studio 中报了这么一个错 ： libpng error: Not a PNG file
说我的图片不是PNG
原因：偷懒，直接将图片重命名.png,比如我之前是.jpg什么的。
解决方案：随便找个图片转换器将图片真正转为 png即可
AAPT err(Facade for 1191041091) : No Delegate set : lost message:libpng error: Not a PNG file
当出现这个问题时，是因为本来是 jpg 或其他格式的图片存成了 png 导致的。或者有的图片本来就是 jpg 的，Android Studio 一编译，发现不是 png 才造成了这个问题。解决这个问题可以在 Android Studio 中打开每张图片，查看右上角是否有 jpg 的字样，如果有 jpg 的字样而且图片是 png 后缀的，那么把这张图片通过图片浏览器打开，然后另存为 png 格式，替换原来的图片即可。
AAPT err(Facade for): libpng error: Not a PNG file 错误
在导入项目到Android studio后，若编译出现“AAPT err(Facade for): libpng error: Not a PNG file”错误。
该错误表示项目中的drawable下的图片文件有非png图片，命名为了png造成的。
解决方案：
方案一、在模块下的build.gradle中配置下面两个信息，再clear project。
aaptOptions.cruncherEnabled = false
aaptOptions.useNewCruncher = false
如：
方案二、在android studio中，依次点开后缀为png的图片，可以查看到图片的文件信息，如下图，将不为png的图片另存为png图片或者修改图片后缀为对应的图片格式。
Android libpng warning: iCCP: Not recognizing known sRGB profile that has been edited
今天更新了Android Studio，编译项目的时候出现了这种问题，所有的drawable里的png格式的图片资源全部报libpng warning: iCCP: Not recognizing known sRGB profile that has been edited
这个错误。Google有说可已忽略，但是我之前的旧版本Android Studio 并没有这种错误，还有一种说法是
It''s metadata added by tools like Photoshop that isn''t even honored by Android。
后来我更改了build tools 到19版本这个错误才消失，请问这个错误到底是什么呢？

mavenCentral()

// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
jcenter()
}
}
恢复到类路径“com.android.tools.build:gradle:1.3.1”似乎解决了问题,但我想开始使用所有新功能
解决方法
要在应用程序中解决此问题,您需要在gradle中指定选项
aaptOptions{
cruncherEnabled = false
}
这是对所有png文件禁用AAPT优化.
