Feeling as if your G1 is a little bland in the animation department? Want those fancy sliding animations generally reserved for Google’s demonstrations? Worry no longer – afbcamaro from XDA Developers noticed that you can use a development package from the Android SDK that allows for you to access some fun features (such as sliding transitions) that didn’t make their way in to the end product.
What you need:
- T-Mobile G1
- APKInstaller (download it from the AndroidMarket), Development.APK (Download link), and a MicroSD card.
How to do it:
- Make sure you have APKInstaller from the Android Market, and Development.APK from here (If you want, you can point your browser directly to that link from your phone and bypass all the following steps. Thanks to Mark Murphy for the tip!).
- Put the Development.APK in the root directory of the MicroSD card. In other words, put it at the very first section of the card – don’t go making a folder named “root”.
- Launch the APKInstaller, navigate to the file you just placed on the MicroSD card, and install it. This will install an application called “Dev Tools”
- Open Dev Tools, then select Development Settings. Scroll down to the bottom, and change Window Animation Scale to 1x, and Transition Animation Scale to 1x (or play around with them for varying effects).
Enjoy!

I don’t think you need APKInstaller. Just visit the link for Development.APK, and when the Mediafire page is ready, click its link to download it. Mediafire is already set up to serve APKs properly such that Android will launch the installer, without you having to go through the gyrations of installing APKInstaller and putting the APK on the SD card.
At least, that worked for me.
Heck why go to all that trouble? Why not just download the “DroidSans Tweak Lite” app from the Market. Already has the capability to enable the transitions.
@Rick: The reason we didn’t include that application in our post is because it’s 3rd party, whereas this Dev Tools application is directly from the source, Google. Plus, by installing the Dev Tools app there is a few other cool things included with it (such as an actual compass option when you are in Maps)
can you load any other things?
like games or apps?
