Android Debugging with Eclipse - No Breakpoints

Question

I am trying to debug a simple Android application on either the emultor or a device and I cannot get the debugger to stop on any breakpoints I have set. I have combined the other posts here and throughout the web and tried all the suggestions (Add debuggable:"true" to the manifest, stop and start adb, Clean all, make sure I use the debug button not the run button, etc etc). In the Debug perspective I can see the threads and in DDMS it shows the debug icon next to the device I am debugging on. I do see the blue dots where I set the breakpoint and the Debug perspective lists them and says they are active.

I have put in alerts just before the breakpoints to verify the code is getting executed.

Starting to go crazy here. Any other suggestions? I must be missing something simple but non-obvious.

UPDATE: I appreciate the responses so far. Unfortunately they have not solved my problem. I have followed the instruction on debugging and have debugging turned on in the phone. Also, I do see the "Waiting for debugger" alert on the phone when starting. In general everything says I am debugging (including getting logcat output that I have added). It just will not stop on breakpoints that I have added and are listed in the breakpoints tab in the Debug perspective. Also just to reiterate - this happens when debugging on the device as well as on the emulator. One thing I do notice is that when I launch the debugger I have it set to bring up the Android Device Chooser. In there the "debug" column is blank for my device - but if the emulator is running the debug column does say 'Yes'. Also the console states that is attempting to connect to the debugger. Should there be a console log that states that the debugger successfully connected? I do not see this.

UPDATE 20120914: I have been away from this for some time and had given up previously. Back to try and tackle this. It is still not resolved. Everything above is still current - but one other thing I have noticed. I set a Class Load Breakpoint on the main activity and it does stop there. It just does not stop at any Line Breakpoints. I have just updated to the latest JDK 1.7.0_07, Android SDK 20, ADT Plugin 20.0.3. I have used the logcat to output a message and set a breakpoint on this line. I see the message in logcat so I know the code is being executed. The debug window in the debig perspective also does show the android application with a number of threads beneath it and the Devices window in the DDMS perspective shows the application with the green bug icon next to it.

One more thing - when the debugger is running the line breakpoints bullets do not get a checkmark overlaid on them (the Class Load Breakpoint does!). I am guessing this is the root cause - but I don't know why they are not getting this. (By the way skip breakoints is also not set - breakpoints do not have lines through them).

Any new suggestions would be appreciated. I have burned a lot of time on this. It must be something obvious that I am not seeing.

Now I feel a bit stupid writing this post. But I resolved my issue finally. The problem is you cannot set breakpoints in the Javascript code. The part I left out unintentionally is I am writing an app for Android using PhoneGap. Almost all the code is Javascript. I am so used to developing .NET web apps in Visual Studio I just assumed you could set breakpoints in the javascript code. Breakpoints in the Java code happen to work fine. Anyway, Thanks for any suggestions. Do';t know if there are other .NET developers trying PhoneGap development - but maybe this post will help them.
