With the fantastic help of Tim on this thread Controlling Android app with bluetooth mouse/ presenter I added bluetooth remote control of my application. After finishing this, I noticed my apk file went from 175k all the way to 1711k – 10 times larger! I have implemented the bluetooth changes on a test application without seeing any change in file size so I am not sure what caused this. I did have some kind of Eclipse problem in the middle of this and had to do a rebuild to get the source to run again so maybe that had something to do with it.
Searching for file size change here and on Google gives me questions of people who want to make larger files to hold more stuff, not my question. I can’t seem to find relevant answers.
The application has no graphics, pdf’s, or other files of any size at all. It just reads some GPS stuff, does some math, and displays the results as text.
Is there some way to get the file size back down? Is there an Eclipse option? This is my first real (non test) application and it is finished and working but I am concerned with the file size increase.
You can check the contents of
apkfile easily. Anapkfile is simply azipfile with different extension. Just replace.apkwith.zipand unzip it. Then diff the contents with your previous.apkfile and find out what file makes the difference.
