Android applications are pretty easy to use, and some resources can be obtained directly from APK files. Much of this information is available in the XML manifest file that contains all of the relevant information about the app’s friendly name name, version, required SDK level, and more. If an APK has a decipherable package name, you can easily determine what application it is and even its version by looking at just the filename. However, it’s often difficult to determine an app’s true function when looking at com.developername.obscurepackagename.apk.
For these situations, XDA Senior Member dmagician‘s ApkSpy utility for Windows can help. ApkSpy is actually a newer, modified version of a previous application with the same name created by XDA Senior Member ido back in 2011. Thankfully, dmagician decided to give it a refresh, so he modified Ido’s tool and added various useful tweaks.
Once ApkSpy obtains the relevant information for APK files stored on your computer, it can then rename package files in order to help you avoid confusion. And after doing this, it can even install the applications directly to your device using ADB. To use ApkSky on your Windows PC, you must have ADB and AAPT in your system path, or have them in the same folder as the utility’s executable file.
To give this application a try, make your way to the original thread.
