Change Package Name

All Android apps have a package name. The package name uniquely identifies the app on the device; it is also unique in the Google Play store.

In MasterStudy App there is a specific package name that is used: com.example.masterstudy_app. You should change it to your own package name, for example, com.mycompany.name where the Mycomapny will be the name of your brand.

To change the package name you need to follow some steps.

In your Project panel, click on the little gear icon.

Uncheck the option Compact Empty Middle Packages

Your package directory will be broken into individual directories

Individually select the directory you want to rename, and follow these steps:

Right-click it >> Select Refactor >> Click on Rename

Enter the new name and hit Refactor

Click Do Refactor in the bottom and wait a minute to let Android Studio update all changes.

Note: When renaming com in Android Studio, it might give a warning. In such case, select Rename All.

Edit build.gradle (Module: app) file in the Gradle Scripts

Find the 50th line and change “com.stylemixthemes.masterstudyapp” to your package name.

After that click on Sync Now to synchronize Gradle.

Then go to App > Manifests and edit the file AndroidManifest.xml if it wasn't changed automatically.

In the 14th line of AndroidManifest.xml file should be the same package name.

From the Android Studio menu open Build and click on the Clean Project. Wait until Android Studio finishes the process.

After that, in the same menu find and launch Rebuild Project.

This is the final step in changing the package name.
