Rename Android Studio package error: Not a valid identifier name

Renaming from com.example.test to org.example.test: I have only found examples of changing the example part of this, but I need to change the com one.
I have tried Refactor then select Rename package, but I get the message Not a valid identifier name when I enter org.example.test.
Does anyone know the correct way?

The accepted solution did not work for me. I had to do the following:
Create a new package with the desired name (eg. org.example.test)
Move the files from the old package to the new one [android studio correct the package name automatically]
In AndroidManifest.xml, change package="..." to the new one (eg. org.example.test) [maybe this step is not obligatory]
Compile. You will see errors like imports to the old package. Simply correct them one by one [I just found one error]
That's all. It run perfectly after that!

I've had to do the same a few months ago. As far as I know, Android Studio does not bound java packages with the app package. That said, you may have to change your app package (if that's what you want) and your java package.
First, your Java package
Select the 1. Project tab in Android Studio. There's a Settings button. Click on it and check Flatten Packages.
Then, select the package you want to rename. Press Shift + F6 to rename the whole package. If you have more than one package inside com.example.test, Android Studio will warn you "Multiple directories correspond to package..." and ask if you want to rename package or directory. Choose package and it will do its magic.
Unless you have something else other than test under com.example, you're good to go.
Then, your Android app
For this one, I don't know any shortcuts. But if it helps, the app package is mentioned in AndroidManifest.xml and build.gradle for your module.

Change Application Package name through Android Studio

I am aware that this question is asked several times in SO. I have checked below answers posted but doesn't work for me :(
Solution 1
Solution 2
Currently, my application's package name is "com.example.test".I want to change this to "com.example.test.test1".So, I just changed the package name in my manifest file and build the app.
Now ,if I run both the applications seperately with above package names changed from manifest files into device than it should show me different applications.It shows me error as "Failure [INSTALL_FAILED_CONFLICTING_PROVIDER]"
As the package names are different, it should show me different applications in the device instead of overriding one app with other.Help me out.
Any help would be appreciated.Thanks

The packageName attribute is deprecated as of Android Studio V0.0.6 onward. To change the package name of the application, use applicationId instead. Check the release notes here.
Change the applicationId and sync gradle.

If your aim is to have the same application at two instance in the device, it is so easy to do using gradle. You don't need to change package name in the Manifest file, gradle will handle that during the build process for you and do all package renaming under the hood wherever required.
In order to achieve that you need to write a new product flavor for your app inside the main app module's build.gradle file with a different application id(package name). Eg. if com.example.test is your default package name of the app. You can have a different flavor of the same app with a different package name or knows as application id. produltFlavours can be defined inside android tag of your main module's build.gradle file like as shows below.
productFlavors {
app1 {
applicationId "com.example.test.test1"
}
}
Sync your project after making the changes. Now select the build variant from Build Variant tab in left hand panel and hit run. Gradle script will handle all package renaming for you.
Check this once for more details :

What worked for me:
1. Right click package you want to change under java folder|
2. Refactor -> Rename|
3. Rename the package -> press "enter" -> press "Do Refactor"|
4. This updates all the files including the manifest

android eclipse custom version of same project

I want to try 2 difference version of the same app on my tablet.
So imported both project in eclipse with different project name.
I changed the name of the app in the manifest, I changed the icon to be able to recognize them on my desktop ...
I just can't get both on the phone at the same time. I can execute them both, but installing one is gonna erase the other.
I guess its the change I'm looking for is in the manifest.xml, still I can't find it.

You have to change your package name. A Package name must be unique for every app.
From the official doc
Package Name is the package namespace for your app (following the same
rules as packages in the Java programming language). Your package name
must be unique across all packages installed on the Android system.
For this reason, it's generally best if you use a name that begins
with the reverse domain name of your organization or publisher entity.

In Eclipse, in the Package Explorer select the com.xxxx.yyyy in the src/ directory of the project whose manifest you changed. Right click -> Refactor -> Rename. Enter a new package name, e.g. com.abc.test
Then, in the manifest XML, also replace all instances of "com.xxxx.yyyy" with the new "com.abc.test" package name.

How to properly change the package name in AndroidManifest.xml (e.g. in project zxing/barcodescanner)

I'm pretty new to android development, so I hope my question is easy, but not completely stupid. I'm using Eclipse to build an android application. It is based on the barcode-scanner of the ingenious guys from zxing. I already did quite some changes to the original code and everything works fine. But I still have the problem, that the original barcode-scanner and my app cannot run simultaneously on one mobile device. As far as I could find out, the problem is the package name. So I tried to change it to something else. But that srew up my entire project, because I can't access my resources anymore (e.g. findViewById(R.id.btDone); <-- R cannot be resolved to a variable).
Can anyone tell me what else I have to change to make my code work again?
This the beginning of my AndroidManifest.xml where I tried to change the package name:
<manifest
xmlns:android="http://schemas.android.com/apk/res/android"
package="com.google.zxing.client.android"
...
I also found an interesting entry in build.properties: (?!)
application-package=com.google.zxing.client.android
Thanks you guys!

This should do it: Right Click on project -> Android Tools -> Rename Application Package

Android - Package Name convention
The package refers to the file directory you made. If you still have problems, especially with android, sometimes doing project->clean and then rebuilding fixes some of the linking problems with resources

Assuming you choose to go with the new package name:
com.superscanner.android
And with the old package name being (for example):
com.google.zxing.client.android
Go through all the source code and change:
import com.google.zxing.client.android.R;
To:
import com.superscanner.android.R;
You'll also have to rename all your directories to match your new package structure, and change your import and package statements throughout, but this should get you going.

android in app billing package name change

I'm trying to run the in app billing sample code. I try to change the package name from com.example.dungeons to com.mydomain.dungeons. I change the package name by right clicking on the project name, then Android Tools ==> Rename Application Package. After I enter the new package name, I get a bunch of warnings because it adds an import to every class file like so:
import com.mydomain.dungeons.R;
What does this line mean? Also, I notice the package declaration for each class is still:
package com.example.dungeons

You just told the Android tools that your package changed. This caused the ADT to re-generate the R class with the new package declaration and changed the package in AndroidManifest.xml; it also updated all references to the R class in your code for you.
You still have to actually rename the package declarations in your code, preferably by using an Eclipse refactoring (right click on the package, etc.).

eclipse import your ID of elements.
and you have standard android elements(layout, Widgets etc)
