Android Studio 1.2 beta version hangs on debugging

I’ve just upgraded Android Studio from version 1.0 to 1.2 beta and I can no longer perform any kind of debug operation. If I set a break point, Android Studio hangs and it can’t resolve the command:

Waiting until last debugger command completes

but it never completes.

    Thanks!

    It looks like a bug in Android studio. It’s reported here: https://code.google.com/p/android/issues/detail?id=73828

    Here is an answer from Google regarding problems with current versions of Android Studio running with pre M version phones –

    For anyone else who might encounter this issue, here is a summary:

    The issue shows up in one of two ways: Studio will be responsive, but
    the debugger will be stuck at either “Collecting Data..” or “Waiting
    for last debugger command to complete..”. This happens on both Dalivk
    and ART, so all versions of the platform are affected. The issue is
    more prevalent with Studio 1.2, but exists on all versions of Studio.

    The correct fix for this issue is in the platform. The next version of
    M preview is likely to have this fix (in progress CL here:
    https://android-review.googlesource.com/#/c/152715/)

    Until then we have some workarounds which reduce the probability of
    hitting this issue. So if you encounter this issue, you can try one of
    the following:

    1. Change your breakpoint to only suspend the thread where it is hit rather than all threads. See comment #82 for more info on how to do
      this. The next release of Studio 1.2 and Studio 1.3 will be make this
      the default. (https://android-review.googlesource.com/#/c/152715/)

    2. You can turn off various settings in the debugger that invoke methods: These include: a) inline debugging
      (https://www.jetbrains.com/idea/help/inline-debugging.html) b)
      “Enable ‘toString()’ object view” (Settings | Debugger | Data Views |
      Java) c) “Enable alternative view for Collections classes” (Settings
      | Debugger | Data Views | Java)

    The 2nd option is more severe (it limits the amount of automation the
    debugger does for you), so we are not enabling that by default.
    However, if you still see the issue after changing the suspend policy
    to thread only, then unfortunately, you’ll have to do the steps in 2
    as well.

    Finally, if you still see the issue after both, then that would be a
    new bug. Please file a new bug with a test case.

    Thanks everyone for your patience and your help in providing us with
    repro cases and stack traces.

    This happened to me too.

    I am running on a Mac so all I had to do was remove the Android Studio.app from /Applications and reinstall Android Studio although I reinstalled version 1.1.0

    I understand that the settings folder name changed from version 1.1.0 to 1.2 so that made the above possible.

    Try to restart the Android Studio and the emulator if you’re using one. This works for me

    I’m still experiencing this problem, after the final release version. I found that restarting my PC solved it (for half of the day). This is not an ideal answer, as you’re question is about downgrading, but if you’re not too bothered at restarting your PC maybe twice a day, you might want to hang onto 1.2 till they fix it.

    Latest Android Studio changelog says it is fixed in version 1.3 Preview 3.

    Hooray!

    I have experienced the very same behaviour (Android Studio blocking in debug) and discovered that it does not seem to occur when using Nexus 7 with Android 5.1 installed. It does reproducibly occur on a SAMSUNG SM-T110 with Android 4.2.2. I habe never tested with an emulator however. This could mean, that the target device might be responsible for the hang.

    Just unplug your USB connected device does the trick for me!
