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
What if this doesnt work

A story from my personal experience about driver
In 2021, I started to work as a IT Technician on an organization. During my time, I was tasked to connect a display to a PC using USB TO VGA adapter. As a normal technician, I connected the display using the USB to VGA adapter. However, It was not working. I realized it should have something to do with driver. So I installed the driver from their website. It was a perfect match, but somehow that PC started crashing cannot always go to startup repair screen.
To solve the issue, I had to format the PC. Later I used double driver to copy the driver from another PC which already is connected using the USB to VGA adapter. And finally, It worked fine. So its better to backup the drivers and use it on compatible PC, instead of trying new ones from the internet.
This is a common issue for many people. Somehow double driver also did not find the driver you are looking. It’s rare, But it might happen. So let me tell you what you need to do if you ever face a situation like this.
Instead of randomly google searching for driver, you need to care fully identify the manufacture brand and go to their website. Once you reach their website head over to download section which will most probably be under the support section. Once you go their most likely you can enter the model number of the product. This way they will show you the real and updated driver for your PC. It’s not recommended to install drivers from websites that are not original manufactures.
Is there any software that will help me find the drivers?
There are software’s that you can install on your PC and it will search for the driver based on your system hardware specifications. But the downside of these software’s is that they all come with a pricing. Of course, they have a free package, but it wont cover it all. One of the famous software for this is Driver Boosters
