Change Package Name In Android Studio

broken image


Use the Rename refactoring to change names of symbols, files, directories, packages, modules and all the references to them throughout code.

  • In Android Studio, you can do this: Goto your AndroidManifest.xml file. Place your cursor in the package name like shown below. Don't select it, just place it. Then press Shift + F6 you will get a popup window as shown below select Rename package. Enter your new name and select Refactor.
  • Right-Click Refactor Rename. In the new window press Rename package. Change name and press Refactor. And press Do Refactor at the bottom. Your package name usually is in format com.domain.appname, in this example we changed the appname part, but you can do the same steps for the domain too.
  • Another good method is: First create a new package with the desired name by right clicking on the Java folder → New → Package. Then, select and drag all your classes to the new package. Android Studio will refactor the package name everywhere. Finally, delete the old package.

Usually package name in Android Studio resembles something like this - com.vishal.someapp. There are different ways to rename package name for your app in Android Studio. It depends on which part of the package name you want to rename. If you just want to rename the last part, (i.e someapp in the example above), it is relatively easier. Another good method is: First create a new package with the desired name by right clicking on the Java folder → New → Package. Then, select and drag all your classes to the new package. Android Studio will refactor the package name everywhere. Finally, delete the old package.

Renaming local variables or private methods can be done easily inline since only the limited scope is affected. Renaming classes or public methods could potentially impact a lot of files. Preview potential changes before you refactor.

When you rename methods that are declared in interfaces, you can also review and rename their implementations as well. The refactoring changes are displayed on the Refactoring Preview tab in the Find tool window.

Rename code in place

  1. In the editor start renaming a parameter, a method, or other code element. IntelliJ IDEA will display in the gutter.

  2. Click the gutter icon or press Alt+Enter and apply a suggestion.

    IntelliJ IDEA renames the code element and updates its usages accordingly.

Rename a directory or a module

  1. In the Projects tool window right-click a directory or a module that you want to rename.

  2. From the context menu, select Refactor | Rename (Shift+F6).

  3. In the dialog that opens, select what you want to rename. If you have a module with one content root, and it has the same name as your module, you can rename them both simultaneously.

  4. In the dialog that opens, add the new name, check where to search for references and click OK.

Change Apk Package Name

Rename a package

  1. In the Project tool window, click Project and select Packages from the list. IntelliJ IDEA lists all the packages in your project.

  2. Right-click the package you want to rename and from the context menu, select Refactor | Rename (Shift+F6).

    If you have multiple directories that correspond to the package, or the package contains directories in the libraries that cannot be renamed, IntelliJ IDEA will display a warning. However, you can proceed with one of the offered options in the warning. IntelliJ IDEA opens the Rename dialog where you can enter the new package name and click Preview to see what directories and files will be affected before you decide to refactor. If you want to undo the changes you have made, press Ctrl+Z.

Rename a code element

  1. In the editor, select an element you want to rename. If you need to rename a file, select one in the Project tool window.

  2. Press Shift+F6 or from the main menu, select Refactor | Rename.

    When you invoke the rename Shift+F6 action, IntelliJ IDEA displays and next to the highlighted element.

    You can press Tab to open the context menu and select the additional rename options.

    If you want to see the Rename dialog with more options, click the More options link or press Shift+F6.

  3. Open (Shift+F6) the Rename dialog. Enter a new name of the element to enable the Preview and Refactor buttons.

    You can specify additional options. For example, specify where to search for element occurrences, or what else to rename. You can also specify a scope for the refactoring.

  4. Click Preview to see the potential changes or click Refactor.

    When you click Preview, IntelliJ IDEA opens the Find tool window with the results of found usages where you can check the results and confirm the refactoring (Do Refactor).

Next time you invoke the Rename refactoring, IntelliJ IDEA remembers the options you have specified inside the Rename dialog.

You cannot rename the .idea Microsoft adobe free download. project directory since IntelliJ IDEA always reads the project files from the directory with that exact name.

Examples

Let's rename a class MyClass.

BeforeAfter
public class MyClass { // some code here } public void myMethod(){ MyClass myClass=new MyClass(); }
public class YourClass { // some code here } public void myMethod() { YourClass yourClass = new YourClass(); }

Every Android app has a unique application ID that looks like a Java packagename, such as com.example.myapp. This ID uniquely identifies your app on thedevice and in Google Play Store. If you want to upload a new version of yourapp, the application ID (and the certificate you sign itwith) must bethe same as the original APK—if you change the application ID, Google PlayStore treats the APK as a completely different app. So once you publish yourapp, you should never change the application ID.

Your application ID is defined with the applicationId property in yourmodule's build.gradle file, as shown here:

Package

When you create a new project in Android Studio, the applicationId exactlymatches the Java-style package name you chose during setup. However, theapplication ID and package name are independent of each other beyond this point.You can change your code's package name (your code namespace) and it will notaffect the application ID, and vice versa (though, again, you should not changeyour application ID once you publish your app). However, changing the packagename has other consequences you should be aware of, so see the section abouthow to change the package name.

And although the application ID looks like a traditional Java packagename, the naming rules for the application ID are a bit more restrictive:

  • It must have at least two segments (one or more dots).
  • Each segment must start with a letter.
  • All characters must be alphanumeric or an underscore [a-zA-Z0-9_].
Android

Note: The application ID used to be directly tied toyour code's package name; so some Android APIs use the term 'package name' intheir method names and parameter names, but this is actually your applicationID. For example, the Context.getPackageName() method returns your application ID.There's no need to ever share your code's true package name outside yourapp code.

Caution: If you are using WebView,consider using your package name as a prefix in your application ID; otherwiseyou might encounter problems as described in issue211768.

Change the application ID for build variants

When you build an APK for your app, the build tools tag the APK with theapplication ID defined in the defaultConfig block from the build.gradle file(as shown below). However, if you want to create different versions of your appto appear as separate listings on Google Play Store, such as a 'free' and 'pro'version, you need to create separatebuild variants that each have a differentapplication ID.

In this case, each build variant should be defined as a separate productflavor. For each flavorinside the productFlavors block, you can redefine the applicationIdproperty, or you can instead append a segment to the default application IDusing applicationIdSuffix, as shown here:

This way, the application ID for the 'free' product flavor is'com.example.myapp.free'.

You can also use applicationIdSuffix to append a segment based onyour build type, as shown here:

Because Gradle applies the build type configuration after the product flavor,the application ID for the 'free debug' build variant is now'com.example.myapp.free.debug'. This is useful when you want to have both thedebug and the release build on the same device, because no two APKs can have thesame application ID.

Remember that APKs with different application IDs are treated asdifferent apps in Google Play Store. So if you instead want to use the same applisting to distribute multiple APKs that each target a different deviceconfiguration (such as the API level), then you must use the same application IDfor each build variant but give each APK a different versionCode. For moreinformation, read aboutMultiple APK support.

Caution: For compatibility with previous SDK tools, ifyou do not define the applicationId property in yourbuild.gradle file, the build tools use the package name from theAndroidManifest.xml file as the application ID. In that case,refactoring your package name also changes your application ID.

Tip: If you need to reference the application ID in yourmanifest file, you can use the ${applicationId} placeholder in anymanifest attribute. During a build, Gradle replaces this tag with the actualapplication ID. For more information, see Inject Build Variables intothe Manifest.

Change the application ID for testing

By default, the build tools apply an application ID to yourinstrumentation testAPK using the application ID for the given build variant, appended with.test. For example, a test APK for the com.example.myapp.free build varianthas the application ID com.example.myapp.free.test.

Although it shouldn't be necessary, you can change the application ID bydefining the testApplicationId property in your defaultConfig orproductFlavor block.

Note: To avoid name collisions with the app under test, the build tools generatethe R class for your test APK with a namespace based on the testapplication ID, instead of the package name defined in the manifest file.

Change the package name

Although your project's package name matches the application ID by default, youcan change it. However, if you want to change your package name, be aware thatthe package name (as defined by your project directory structure) should alwaysmatch the package attribute in the AndroidManifest.xml file, as shownhere:

The Android build tools use the package attribute for two things:

  • It applies this name as the namespace for your app's generatedR.java class.

    Example: With the above manifest, the R classwill be com.example.myapp.R.

  • It uses it to resolve any relative class names that are declared in themanifest file.

    Multiscatter for 3ds max 2014. Example: With the above manifest, an activity declared as is resolved to becom.example.myapp.MainActivity.

As such, the name in the package attribute should always match your project'sbase package name where you keep your activities and other app code. Of course,you can have sub-packages in your project, but then those files mustimport the R.java class using the namespace from the package attribute, andany app components declared in the manifest must add the missing sub-packagenames (or use fully-qualified package names).

If you want to refactor your package name completely, be sure you update thepackage attribute as well. As long as you use Android Studio's tools to renameand refactor your packages, then these automatically stay in sync. (If theydon't stay in sync, your app code can't resolve the R classbecause it's no longer in the same package, and the manifest won't identify youractivities or other components.)

How To Change Package Name In Android Studio 2020

You must always specify the package attribute in your project's mainAndroidManifest.xml file. If you have additional manifest files (such as for aproduct flavor or build type), be aware that the package name supplied by thehighest-priority manifest file is always used in the final merged manifest.For more information, seeMerge multiple manifest files.

Android Studio Change Project Name

One more thing to know: Although you may have a differentname for the manifest package and the GradleapplicationId, the build tools copy the application ID into yourAPK's final manifest file at the end of the build. So if you inspect yourAndroidManifest.xml file after a build, don't be surprised that thepackage attribute has changed. The package attributeis where Google Play Store and the Android platform actually look to identifyyour app; so once the build has made use of the original value (to namespace theR class and resolve manifest class names), it discards that valueand replaces it with the application ID.
