Go Android developed the app on the phone where the installation path is?

One, where is the installation path?

Android app installation involves the following directories:

The System/app system comes with an application that cannot be deleted.
Data/app User program installs the directory, has the delete permission. Copy the apk file to this directory during installation.
Data/data Store the data for the application.
Data/dalvik-cache installs the Dex file in the APK into the Dalvik-cache directory (the Dex file is the executable file for the Dalvik virtual machine, which is approximately one-fourth of the original apk file size).
App installation process: Copy the APK installation package into the Data/app directory, unzip and scan the installation package, save the Dex file (Dalvik bytecode) to the Dalvik-cache directory, and create the corresponding application Data directory in the Data/data directory.

App Uninstall process: Delete files and directories created in the above three directories during installation.

Second, how to view the installation path folder?

Use Eclipse's DDMS tool to view.

Android Ddms is connected to a real machine (root), and there is usually a problem with file explore not seeing the Data/data folder. The reason is insufficient authority, the following is the workaround:
The problem is no permission, with 360 mobile phone helper or pea pod is also invisible. The simple way is to use the RE file manager (full name root Explorer, the phone needs to grant Root), the data and Data/data set to 777 permissions. Note: Open with the RE manager to see the default is not 777, but can read or write or not enough. Here's how to open permissions:

As a result, DDMS can view the Data/data folder, but sub-folders under that directory, such as Com.android.XXX, need to continue to release permissions.
