If you have ever ported an Android app to a different screen resolution or themed it using another app’s image resources that came from a phone with a different resolution, you know how much of a hassle it can be to manually resize all the PNG files to the right dimensions. This can be especially cumbersome with NinePatch files. With Android Resizer Tool, all your PNG resizing worries should now be a thing of the past.
Developed by XDA Senior Member Peteragent5, Android Resizer Tool is a fork of the open source Android Drawable Converter project, and it allows you to automatically resize the PNG files in APKs to XHDPI, HDPI, MDPI and LDPI screen resolutions. There is also a batch file provided to further automate this process.
So what are you waiting for? Head over to the forum thread, download the tool, and follow the instructions provided to speed up your Android app porting and make it hassle-free._________
