Within Processing for android, I recently use the sdk updater. Since that update, I have not had a successful build on a sketch that was working on both the emulator and a device. The only thing I had done was the sdk updater. The error stream high mentions Gradle and suggests checking the [gradle.org](http://gradle.org) website. I don’t understand Gradle enough. Can anyone help make it clearer for me?  
Thanks all

In Android mode, under the Android menu heading is SDK updater. I’m not sure which SDK the updater updates. Every so often I check for updates. If they’re available I update. The recent update causes the build to fail. This is the beginning of the error stream:  
FAILURE: Build failed with an exception.

- What went wrong:  
Execution failed for task ‘:app:transformDexArchiveWithExternalLibsDexMergerForDebug’.

> java.lang.RuntimeException: java.lang.RuntimeException: com.android.builder.dexing.DexArchiveMergerException: Unable to merge dex

- Try:  
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

Ok, I managed to fix this issue. I did a fresh Processing 3 install and uninstalled the libraries involved with the sketch and reinstalling them.

Same issue, same fix. Reinstalled libraries and Android Mode with a fresh download of Processing 3 and there was no longer a problem. Thanks!
