String resources, extract strings that are hardcoded, these string won't be translated if the system is using some other language. Add appropriate android api in app.gradle file. Make sure everything is working fine and that there no extra debugging details available on the UI.  Once you're ready : Click on the Build option in the Options on the Top. Select Generate Signed APK Create Key for app, make sure you keep the key file safe, because when updating the file you might need this file again. Set a password and key store path Finish the process You will get a message showing the completion ...

Many of you will agree that Android's AVD is slow and it does affect the complete development process. But if your work device has good specs, like more than 4GB of RAM, then you are lucky ones. But I had the problem with the virtual device, hence I used the best alternative. So let's discuss why is the Virtual Device slow. 1. It eats up a large amount of memory Android Studio itself takes up about 2GB of RAM approx. The remaining is reserved for the OS to function and if you accidentally click on run and a virtual device is starting you're in trouble. What I do during this situation is I shut down my PC.  Also, VD is not meant to run that fast since it's working on some other structure. So you can't expect it to run as needed. 2. Let's come to the main point Which is the best alternative? I tried around 5 alternatives over the internet, then, at last, I came to the one. It's Genymotion, great speed and easy. Now I'll tell you how to us...
