Where does Android app package gets installed on phone
You will find the application folder at:
/data/data/"your package name"you can access this folder using the DDMS for your Emulator. you can't access this location on a real device unless you have a rooted device.
System apps installed /system/app/ or /system/priv-app. Other apps can be installed in /data/app or /data/preload/.
Connect to your android mobile with USB and run the following commands. You will see all the installed packages.
$ adb shell $ pm list packages -f
An application when installed on a device or on an emulator will install at:
/data/data/APP_PACKAGE_NAMEThe APK itself is placed in the /data/app/ folder.
These paths, however, are in the System Partition and to access them, you will need to have root. This is for a device. On the emulator, you can see it in your logcat (DDMS) in the File Explorer tab
By the way, it only shows the package name that is defined in your Manifest.XML under the package="APP_PACKAGE_NAME" attribute. Any other packages you may have created in your project in Eclipse do not show up here.
