Android Change Package Name

Change Package Name In Android Studio - Changing Package Name is a crucial part of any Android application as many of the core libraries and R.java file depends on the package name. Change Package Name: Right Click on Project Android Tools Rename Application Package. Go to src right click on your main package Refactor Rename. Go to manifest file and change your package name.

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. Apk editor pro is the best alternative of apktool for android and apktool for windows.It can edit android apps without doing any setups. The best feature of this is that you can edit smali files means anyone with knowledge of smali coding can change app code. Here is the features of apk editor Features: 1. Change app name.

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:

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_].

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.

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

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.

Android Studio How To Change Package Name

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.

  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.)

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.

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.
