AOSP Plugin for Eclipse
I had this pointed out to me today. This is something of a Gold Mine to the Android developers community. If you work with Source code, and have worked with apps in eclipse then you already know how convienent it is to have eclipse notify you of an error as you type the code! This has been long over due and I'm sure will lead to more and more people working with source code. Once you install the plugin, you can load Android source code into eclipse like an app and make your edits there.
Taken from my theme guide for setting up tools:
This is called Eclipse Indigo download the one called Eclipse Classic
Once again you extract this file into a folder on your computer like you did with APK Manager. I created the folder @ C:\eclipse\
Now navigate to this website to learn how to add the adroid sdk into eclipse to have it ready when we are going to need it.
Note the android SDK download at the top, you should already have this. Read right below where it instructs you to add that into eclipse.
Start out like this. Open Eclipse now that it is installed. It's the icon in the eclipse folder that looks like a purple planet. With Eclipse open on your screen click on Window in the tool bar at the top. Click on Help-Install new software. The box that appears, it says "type or select a site" ignore this text input box and go straight to click "Add" button. When it comes up name it Eclipse Plugins and in the field where you put the web address, type the following: https://dl-ssl.google.com/android/eclipse/ . Click on the box next to developers tools and click next at the bottom. This will install what is called Android SDK and AVD Manager. Eclipse will probably need to restart to add the plugin to the menu list. Alternatively, if you get errors doing this there is a problem with you computer connecting to the secure server (in the web address you typed https: note the S at the end. If, for any reason you do get errors, simply go back to Help-Install New Software, and this time put in the web address field http://dl-ssl.google.com/android/eclipse/ When eclipse opens back up, click on Window and select "Android SDK and AVD Manager". Now your screen should look like the pictures in the link.
Now Eclipse Should be upgraded.
Next, to install the plugin, directions from Artem Russakovskii post at Android Police original thread here: CLICK ME
Here's how to get it up and running in a few clicks:
Start Eclipse, go to Help -> Install New Software.
Enter http://adt-addons.googlecode.com/svn...source.update/ into the Location field and whatever you want into the Name field. Press OK.
Now Select the newly added repository from the dropdown in the Work with prompt. You should see Android Sources as the only available plugin:
Press Next, then Finish, wait, and restart Eclipse at the prompt.
Voila - you're done. You should now be able to step into any Android class (this excludes native functions, however) and examine the source code. Do it during debugging or regular development and stop staring at boring class definitions.
Code our next favorite app.
OP updated changed Eclipse 3.5 dl link to 3.7.1
