How to update an old Android project for updates in the new Android SDK tools?

Question

I used to use an older version of Android SDK Tools , and now I switched to a new computer, set up a new development environment from scratch and copied and imported projects from a previous PC. Now, if I create a new project in the current environment, I notice that the SDK creates the proguard.cfg file in the root folder of the project, which I did not see for any of my previous projects in the previous setting. I was looking for using proguard.cfg and that sounds useful. But this proguard.cfg file is missing in the projects that I created in the previous setup.

And it also makes me think that the new SDK tools may also have some new updates and / or additions to features that I could use. I have to mention that the target platform I use is the same - Android 2.2, but the “Android SDK Tools” have been updated. In addition, I am not getting any errors yet, but, as I said, I want to use updates for the SDK tools (and not for updates to the target platform).

So my question is: is there a way to guarantee that I will not miss anything updated by the Android SDK, for example, proguard.cfg, or will I need to identify such things and manually add the file, and similarly for any other things that have improved in new tools SDK

The Android SDK tools directory has an android executable. You can use this to update the project by passing the path to the directory containing AndroidManifest.xml:

 $ANDROID_SDK/tools/android update project -p /path/to/my-android-project 

This is registered on the SDK website under Project Management from the Command Line> Project Update.

The Eclipse plugin does not do this automatically, and there is no equivalent section in Project Management from Eclipse using ADT , so it looks like you should use the command line tool.
