What execution failed for task app mergedexdebug?

When you build the android app, It creates .dex file. If you extract a apk file also, you will be able to see this file. What’s happening is that the app cant fit all imported packages into one single .dex file. This is why It is happening. usually this error occurs when you have imported many packages to your your app.

How did we solve this issue?

By enabling multiDexEnabled to true you are giving permission to create more than one .dex file. This way it will create two or more .dex file if required. Anyway, the fix is to add multiDexEnabled true to your app/build.gradle
