I am new to phonegap and android development. May I know how can I debug javascript error on the emulator? I have heard about ADB may I know how can I use and install it on windows 7 system? I have an ajax called with jsonp but no response on emulator. However, I can call that ajax with browser on windows. May I know what went wrong?
Update Nov 2016: looks like this doesn't work anymore.
The easiest and one of the most powerful ways is using http://debug.phonegap.com (it uses Weinre in the background, if you care). You just
r4nd0m
,<script src="http://debug.phonegap.com/target/target-script-min.js#r4nd0m"></script>
into your index.html
http://debug.phonegap.com/client/#r4nd0m
and you will instantly be debugging your mobile web app.Things you can do (similar to Firebug or Web Inspector):
You could at least log debug stuff to the adb console by calling console.log() in JavaScript. Maybe that would suffice?
To view log output using adb, navigate to your SDK platform-tools/ directory and execute:
adb logcat
See logcat Command-line Tool
You can now use Chrome dev tools to remotely debug Android Phonegap apps! I wrote up instructions here: Remote debugging Phonegap apps with Chrome Dev Tools

I'd recommend jsconsole. It lets you inject any JavaScript into the page and provides a basic console. There's a nice tutorial on remote debugging.
