I found another solution for renaming a package in the entire project:

<ol>
<li>Open a file in the package.</li>
<li>IntelliJ displays the breadcrumbs of the file, above the opened file.</li>
<li>On the package you want renamed: Right click > Refactor > Rename. </li>
</ol>

This renames the package/directory throughout the entire project.

blocks|key|260049|text|我找到了一个很好的解决这个问题的方法。以问题中提到的示例为例，将包名从com.example.test改为com.example2.test的步骤如下：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|260050|Intellij项目创建一个临时目录，在目录test).|260051|Go旁边的example中创建一个临时目录，然后选择文件夹com.example并单击Shift+%2B+F6。现在，它提出将文本重命名为example。您可以在此处输入所需的新文本，IntelliJ将为您完成其余操作。|unordered-list-item|260052|

I found a good work around for this problem. Taking the example mentioned in the question, following are the steps for changing the package name from <code>com.example.test</code> to <code>com.example2.test</code> :

<ol>
<li>create a temporary directory, say <code>temp</code> inside the directory <code>example</code> (alongside directory <code>test</code>).</li>
<li>Go back to the Intellij project, select the folder <code>com.example</code> and Click <code>Shift + F6</code>. Now it offers to rename the text <code>example</code>. Here you can enter the new text you want and IntelliJ will do the rest for you.</li>
<li>Delete the temporary directory <code>temp</code> from the file system.</li>
</ol>

This idea can be used to refactor any part of the package name.

Good luck!!

What worked for me in Android Studio:

<ol>
<li>do a 'move' on the package to a new package name you want.(right
click on package and select Refactor -> Move)
If Refactor -> Move didn't work for you, then create a package with the name you want and move manually in the existing package to the new one, and then delete the old empty package. </li>
<li>Change package name in manifest (manually)</li>
<li>Have a replace for the old package name with the new package name
globally (in the full path by going to Edit -> Find -> Replace In
Path)</li>

What I did was the following :

I simply created the package with the desired name , in the src folder , next to the current package with current name. 

I dragged all contents of current package to new package , intellij popped a dialog box asking me if I want to refactor inside package references and project references to new package , I clicked 'yes' and TA-DAAA , worked like a charm.

Most of the answers even the most voted answers didn't do the job properly, they seem to work and the builds work however, a closer look at the file structure and references will show you that not much was done. IntelliJ actually does this whole process automatically.

1) Go to Project Tab and make sure Packages is the active Tab in the drop down like so:

<img src="https://i.stack.imgur.com/FHrQf.jpg" alt="Select Packages in the drop down">

find your com.example package (note test as in com.example.test is not there) right-click and choose Refactor->Rename...

It will issue a warning that multiple directories... (which is actually the desired effect), click on Rename package.

Input the new package name and Refactor... 

It will do searches and show you refactoring results.

Click on the Do Refactor button and it will do everything and even rename the folders and files involved... every reference is corrected to this new name.

2) Then Finally change the AndroidManifest.xml file

:)

blocks|key|265501|text|我通过从命令行手动更改目录名解决了这个问题。Intellij随后自动识别出新的包名。然后，我必须搜索并替换导入它的每个文件中的包名。这看起来像是一个丑陋的变通办法，但Intellij似乎不愿意改变包的名称。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|265502|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

I solved this issue by changing the directory name manually from the command line. Intellij then recognized the new package name automatically. I then had to do a search and replace for the package name in each file that imported it. This seems like an ugly workaround, but Intellij seemed unwilling to change the package name otherwise.

In addition to @Cristian's <a href="https://stackoverflow.com/a/6600360/3036759">answer</a> above, I had to do two more steps to get it working correctly. I will sum all of it here:

<ol>
<li>Change the package name manually in the manifest file.</li>
<li>Click on your <code>R.java</code> class and the press <code>F6</code> (Refactor->Move...). It will allow you to move the class to another package, and all references to that class will be updated.</li>
<li>Change manually the application Id in the <code>build.gradle</code> file : android / defaultconfig / application ID<a href="https://stackoverflow.com/a/31988188/3036759"> [source]</a>.</li>
<li>Create a new package with the desired name by right clicking on the java folder -> new -> package and select and drag all your classes to the new package. Android Studio will refactor the package name everywhere<a href="https://stackoverflow.com/a/25848132/3036759"> [source]</a>.</li>
</ol>

Super simple approach:

<li>Find <code>R.java</code> in the build/generated directory</li>
<li>Create new package directories, again under build/generated/etc</li>
<li>Move <code>R.java</code> to the newly created package. </li>
<li>A dialog will appear. Choose to refactor the existing code with the new package name.</li>
<li>Clean and Rebuild </li>
</ol>

Done!

Pressing Shift+F6 seems only to rename the last directory. 
For example, in the project <code>com.example.test</code> it will offer to rename test only. The same applies if I navigate to package name in <code>.java</code> or Manifest file and press Shift+F6. 

So is there a way to rename the package?

How do I rename the android package name?

Android Studio

文件系统

Android

Windows

Eclipse

按Shift+F6似乎只是为了重命名最后一个目录。例如，在项目com.example.test中，它将仅提供重命名。如果我导航到.java或Manifest文件中的package name并按Shift+F6，情况也是如此。那么有没有办法重命名这个包呢？
