If you have a slough of apk files with weird names like I do, this DOS tool is for you. It uses AAPT (included) to check an APK file's name and version, and renames your APK in a more human-readable format.
Example:
pp170.apk --> PhotoShake Pro_1.7.0.apk
Installation
Just unzip the file (RenameAPK.zip) to anywhere you like. All the required files are included.
Instructions: GUI
I made RenameApkGUI in an attempt to create a nice tool that can be pinned to the start bar. (Right click on it, choose Pin To Taskbar.) Just like regular RenameAPK, you can drag multiple files to it. You can also open it and drag multiple files into it (this makes for an easier listing of the files you want to convert).
There are a couple caveats to it, however:
When pinned to the Taskbar, you can only drag one file at a time onto its icon.
When pinned to the Taskbar, and you wish to drag a file onto its icon, you must hold the Shift key.
Really, you might as well just open RenameAPK from the Start bar instead of trying to drag/drop to it.
Just released a GUI, which is able to be placed on the Taskbar, and you can drag files to it! (But only one file at a time, and only if you hold shift.)
You can also open the GUI, and you can drag files onto it to convert them.
