Switching to Android Studio with all my existing projects in Eclipse. So what is the procedure to do that.
Try these steps for importing an Eclipse project into Android studio:
1- Click on import project (Eclipse ADT, Gradle, etc.).
2- Choose the root folder of your project. The folder that contains bin folder.
3- Choose where you want to import it and click next.
4- Click on finish.
5- Change the view to project.
6- Open build.gradle in your src folder.
7- You should find out your current SDK version. So, click on tools-> Android-> SDK Manager-> Launch standalone SDK Manager and scroll to the bottom.
8- Change your build.gradle based on your SDK version and click try again. For example, mine is 23.1.1.
