Android Studio - AAPT: error: file failed to compile with PNG images

I was working on Ubuntu linux and recently i pulled my project and started working on Win10.

From now on i cannot Build/Run my app. There must be a problem with those PNG files in the resources folder.

That is the Error output while trying to build the app :

Executing tasks: [:app:assembleDebug] in project C:\Users\Psz\Documents\Android-ChatRoom-Client

I don't know what is causing it. I cleaned cache, delete and pull project again. Also i couldn't find a solution online.

Update Found out that Android Studio on Linux(Ubuntu) works just fine and as a matter of fact this error occurs only on Windows' Android Studio..

In my case this error was only showing in release and not debug build. So i converted the png to webp by right clicking on the image and selecting "convert to webp" option inside android studio. After that the error go bye bye.

In my case, I resolved the issue by selecting "Invalidate Caches" > "Invalidate and Restart" option in Android Studio. Turns out there was nothing wrong with the image files.

I converted all the images to PNG format online on the website, and the problem was resolved.

You can use websites like https://www.photopea.com to re-export the images as PNG

This issue is nothing but a image file extension problem. My image was in jpeg format, but I saved it in my drawable folder as png format. That's why this conflict was thrown by android.

I just convert my image to png version and implemented in my android project and deleted that old jpg image. Then android worked properly.

If it's an expo app remove whatever png assets you just added. You can rename them as jpg and that would work

I encountered a similar problem to this, and the root cause was that a JPEG file was named with a PNG file extension. Once I fixed the file extension AAPT was happy.

I had exactly the same error. Tried everything including pulling my own hear out, but nothing worked. Then someone mentioned running Android Studio as admin would solve the problem... So it has something to do with write access problems. Bingo! Try this:

In windows go to Ransomware protection and disable it!

Then try building again. If that works then use Allow an app through Controlled folder access to give gradle the right access rights. And then enable your Ransomware protection again.

In Windows, try to keep your project in a drive apart from windows (C drive). You can use D drive and try keeping the path short (eg. D:\Projects\XyzProject). This might resolve your issue.

If some files have been encrypted, AAPT may not work properly. Please check whether the files related to the compilation error are encrypted. In your case, these are PNG files.
