Drawables Not Changing After Being Replaced With Others In The Folders

I've created a new theme set for an app of mine, and decided I didn't need the old one anymore. So, I copied my new image files over the old ones, replacing all of them. I did this

Solution 1:

Wipe your bin-folder to remove old compiled data.

Solution 2:

TL;DR: check your other drawable-xxxdpi folders for old versions too!

I had this same problem, and none of the solutions here helped. It was driving me crazy.

I had replaced res/drawable-hdpi/file.jpg with file.png. It was a different extension and had different content. Eclipse was seeing the new version, but no amount of cleaning/refreshing, uninstalling the app or manually deleting bin/gen folders made the device see the new version.

Then I realized that I had other versions in:

• res/drawable-ldpi/file.jpg
• res/drawable-mdpi/file.jpg
• res/drawable-xhdpi/file.jpg

Once I replaced those versions with resized versions of file.png, then a simple re-run of the app fixed the issue. It seems like the Android resource compiler saw a "jpg" version of the file first in another of the drawable folders, then ignored the subsequent "png" version in drawable-hdpi. Even though the device it was running on was hdpi, the drawable was coming out of another dpi folder.

Solution 3:

If checking other Drawable folders for old versions and wiping your bin and gen folders didn't work.

Look for: setImageResource(R.drawable.YourPNG) in your code that might override the drawable configured in xml from: res/layout/ folder.

Solution 4:

Android Studio: If Clean and Build doesn´t work try with

Go to File > Invalidate Caches / Restart

or File > Synchronize

both worked for me.

Solution 5:

The easier solution is to uninstall the app from your emulatorthen reinstall by running it again from Android Studio. (This will force everything to update)

This is always a weird problem but I figured this out by deleting the older images from my pc, yet the older image would still show up on the app (which is impossible). So I figured the problem was with the emulator. (since the emulator has its own storage)

If filepath and file names stay the same I guess Android doesn't update your app, even though the new image is a different size. Weird.
