ERROR: 9-patch image xxxx.9.p malformed. Frame pixels must be either solid or transparent
刚刚在编译项目时，因为要从一个反编译项目中拿出几张图片用到项目中，编译时报以下错误，
target Package: Contacts (out/target/product/wxkjsz89_we_jb2/obj/APPS/Contacts_intermediates/package.apk)
ERROR: 9-patch image packagesxxxxx_holo_light.9.png malformed.Frame pixels must be either solid or transparent (not intermediate alphas).

报这错的原因是：这三张.9图片在反编译时，没有用对方式，导致这.9图片失真，可在XP系统下用office picture manager功能查看.9图片是否反编译成功，如果是成功的，.9图片用office picture manager打开是可以看到图片的各条边的那条线
