What would you like your android package name to be

How to change the Package name in Android

The package name is a unique name to identify a specific app. It is very common we need to change the package name. Here i am going to show two ways to rename package in android app.

** Way 01 **

Step 01: In your Project pane, click on the little gear icon. Uncheck / De-select the Compact Empty Middle Packages option

Your package directory will now be broken up in individual directories

Step 02: Individually select each directory you want to rename, and:

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

Step 05: You may need to change the package= attribute in your manifest.

Step 06: Clean and Rebuild.

Step 07: Done! Anyway, Android Studio needs to make this process a little simpler.

** Way 02 **

Step 01: Go to your AndroidManifest.xml file, put your mouse cursor in front of the part of the package name you want to change.

Step 02: Right-Click > Refactor > Rename

Step 03: In the new window press Rename package

Step 04: Change name and press Refactor

Step 05: Press Do Refactor at the bottom.

Note: Usually package name 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.

Done! You changed your package name! Be sure to give claps if you find this article helpful.

As stated here: Package names are written in all lower case to avoid conflict with the names of classes or interfaces.

Name collisions that occur within a single company need to be handled by convention within that company, perhaps by including the region or the project name after the company name (for example, com.example.region.mypackage).

Packages in the Java language itself begin with java. or javax.

In some cases, the internet domain name may not be a valid package name. This can occur if the domain name contains a hyphen or other special character, if the package name begins with a digit or other character that is illegal to use as the beginning of a Java name, or if the package name contains a reserved Java keyword, such as «int». In this event, the suggested convention is to add an underscore. For example:

Android follows the same naming conventions like Java,

Naming Conventions

Package names are written in all lower case to avoid conflict with the names of classes or interfaces.

Companies use their reversed Internet domain name to begin their package names—for example, com.example.mypackage for a package named mypackage created by a programmer at example.com.

In this event, the suggested convention is to add an underscore. For example:

For the «Hello World» example in android.com, the package name is
«package com.example.helloandroid;»

Is there any guideline/standard to name this package? (references would be nice)

Android follows normal java package conventions plus here is an important snippet of text to read (this is important regarding the wide use of xml files while developing on android).

The reason for having it in reverse order is to do with the layout on the storage media. If you consider each period (‘.’) in the application name as a path separator, all applications from a publisher would sit together in the path hierarchy. So, for instance, packages from Adobe would be of the form:

com.adobe.reader (Adobe Reader)

com.adobe.photoshop (Adobe Photoshop)

com.adobe.ideas (Adobe Ideas)

[Note that this is just an illustration and these may not be the exact package names.]

These could internally be mapped (respectively) to:

com/adobe/reader

com/adobe/photoshop

com/adobe/ideas

The concept comes from Package Naming Conventions in Java, more about which can be read here:*

i also had the same issue

Go to app.json in your react native project folder and add in

and then save it and then go to your terminal and type expo eject

When it asks for Android Package Name, give the name that you have given in your app.json file for android, and similarly for ios.

Then it should work fine and finish the expo eject command.

by default package name & versionCode for android and bundleIdentifier & buildNumber for iOS is skipped in app.json [present in root directory of your project] when you start with expo react native project.

so it is asking the package name when you expo eject.

example of package name >>> «com.yourcompany.yourappname»

so type package name as in example. Replace «com.yourcompany.yourappname» with whatever makes sense for your app.

or

go to app.json and edit manually, add missing fields for ios & android as necessary for your app and then expo eject.

Android:Which one to use for package name? Manifest’s packagename or Gradle applicationId?

The application id specified in the build.gradle will be used.

The entry in the AndroidManifest.xml is overridden

Your AndroidManifest.xml will look like this

There’s a great support article about this here by Android Studio.

Why are there two?

Which one should I edit to change my final package name
The package name in Gradle will overwrite the package name in the Manifest. So you should change it in Gradle.

If you would like to actually change the structure of your project, then you’d need to change your packagename in Manifest.xml

For permissions
In your particular case, the permissions, you ask which package name you should provide for Google Messaging. Since Google Messaging requires your final package name, you should enter your gradle packagename. If you’re using flavours, you should do this dynamically as suggested by @alim’s answer.
