I'm not using 9.png files. How can I fix it?

Answer 1

In my case, it was some corrupted PNG file in resources too. Try going through all of your images and see if you are able to view them in some external preview program.

Answer 2

The problem is related to 1 corrupted image file in drawable. I changed it and the problem was solved very quickly. The answer is very simple, but the error message is rather ambiguous. I changed the gradle and android studio, but the solution was very simple than what I thought.

Answer 3

Check your png files, in my case that was the problem (One picture was a JPEG file with .png at is end) Remove it/them and remplace it/them by "real" png files and it may works

Answer 4

I ran into the same situation as @wooldridgetm.

Later I found that if my 9-patch file has marked stretch area for both left and top side, not only one side, then the problem is solved.

I don't know if it is allowed to have only one side before. Hope this help.

Answer 5

I started getting this error too with Android Studio 2.3 on Mac. Neither disabling the buildCache nor changing the location of the buildCache resolved the problem.

Renaming all of my 9-patch drawables from 'xyz.9.png' to 'xyz.png' - removing the '.9' in the filename - fixed the problem.

Answer 6

I have exactly same problem in Android Studio 2.3. I wasted 2 days to solve this problem.

Your problem is

AAPT err(Facade for 596378712): \\?\C:\Users\Я\.android\build- .....

Folder name of your account(reverse R?) is not ascii folder name, so build-cache cannot recognize your folder.

To Solve:

1. Change folder name : it's impossible in windows 10.
2. not use build cache: Leos Literak's answer. not good solution.
3. Best solution: change build-cache path. refer to https://developer.android.com/studio/build/build-cache.html

For Ex:

in gradle.properties
android.buildCacheDir=D:/android-studio/build-cache

You can build your app cleanly. Thanks.

Answer 7

I have upgraded to Studio 2.3 as well and this error suddenly occured.

AAPT: \\?\C:\Users\Leoš\.android\build-cache\ce4c6faf7b6acf7c9a9f7875a69dc5776c2cfd5b\output\res\drawable-xhdpi-v4\msbp_math_compass.png ERROR: Unable to open PNG file

I realized one similarity in your and my logs: non-ASCII characters in user name. Then I found that it is a build cache directory. And there was info how to turn it on. So I tried to turn it off with:

gradle.properties

android.enableBuildCache=false

And it works! I can compile my project again. I submitted issue 236304 to Google.

Another option is to change build cache location:

android.enableBuildCache=true
android.buildCacheDir c:\\Dev\\Android\\cache\\

Answer 8

The path of the file might be too long for the compiler to build with it. Try moving your project to another location to reduce the length of the destination.
