android studio 复制项目

Using Windows Explorer, navigate to the Android Studio projects directory select the project folder to be cloned;
Copy the selected folder;
Paste the folder into the Android Studio (AS) projects directory;
Rename the pasted folder to be the new name of the cloned project, say 'ViewPager_Shell';
Launch Android Studio;
Select 'Open an existing Android Studio project';
Navigate to the AS projects directory;
Select the folder 'ViewPager_Shell';
Ensure that AS's explorer pane is visible on the left-hand-side of the AS main frame;
Select the 'Android' view for the explorer pane;
Open app -> java; the old package name should now be visible, e.g. 'com.hulme.owm';
Right-click on the old package name and select 'Refactor -> Rename';
A dialog should now appear; left-click 'Rename Package';
In the pop-up dialog, replace the old package (e.g. 'owm') with the new package name (e.g. viewpager_shell);
Left-click on the 'Refactor' button; BEWARE!! ... A new 'Find Factoring Preview' pane should open in the lower-left of the AS main frame window;
Select 'Do Refactor';
Using the AS explorer pane, navigate to 'Gradle Scripts -> build.gradle(Module:app);
Double-click build.gradle(Module:app) to view its contents in the AS editor pane;
Change the defaultConfig 'applicationID' string to your new full package path (e.g. "com.hulme.viewpager_shell");
Using the AS explorer pane, navigate to 'app -> manifests -> AndroidManifest.xml';
Double-click on 'AndroidManifest.xml' to view it in the AS editor pane;
Under the manifest tag, you should observe that the new package name (e.g. 'com.hulme.viewpager_shell') now appears, as a result of the previous refactoring step;
Under application tag, change android:label to a new name (e.g. "ViewPager Shell Demo") - this is the name that appears in the list of installed apps provided by Android's 'Settings -> Application manager;
Under activity tag, change android:label to a new name (e.g. "VP Shell") - this is the name that appears under the app's icon and it is also the activity's default ActionBar title;
You should now be able to build and run the newly cloned project.

2. 复制所选文件夹;
3. 将文件夹粘贴到Android Studio（AS）项目目录中;
4. 将粘贴的文件夹重命名为克隆项目的新名称，例如“ViewPager_Shell”;
5. 启动Android Studio;
6. 选择“打开现有的Android Studio项目”;
7. 导航到AS项目目录;

25. 您现在应该能够构建并运行新克隆的项目。
1：修改包名，定义成你觉得与功能相对应的
2：在工程中找到GradleScripts文件夹下的build.gradle（Module：app）文件中修改
```
android {    compileSdkVersion 19    buildToolsVersion "23.0.3"    defaultConfig {        applicationId "********"        。。。    }
```

applicationId 这个标签，使编译器认为你是新建了一个工程，从而不会覆盖原来的文件目录
