Too Deep Recursion

I am trying to get debugging working for the first time in Ti Studio using the 1.7.1 release and Android. When I launch my app (which works fine when run without debugging), it force closes on this error:

I added this to my tiapp.xml but it had no effect:

<property name="ti.android.threadstacksize" type="int">327680</property>

Was anyone else able to get debugging working? What am I missing?

  • Now that you've added the stack size property, run a clean on your project then rebuild.

    • @Anthony - I don't see any clean option within Ti Studio, however I did try clearing out the build/android folder if that's what you mean. It has no effect, I still get the recursion error.

    • The clean option is under the "Project" main menu. Running it does the same as clearing that android build folder, however, just to cover all bases, try using that option and building again.

    • @Anthony - Same issue after clean…

  • Seems 'ti.android.threadstacksize' should be 32768 rather than 327680 !?

    • I tried both and they give the same error.

  • could you post details.js ? for some advice …

  • Here is details.js, however there are a bunch of shared controls so this isn't all of the code. Keep in mind that running it normally on the simulator or on the device works fine, only debugging gives the recursion error so it makes me think it doesn't have to do with my code at all.

  • Justin

    Please take note of this advice in the docs: Avoid deep nesting

    Setting threadstacksize to very large values is likely to cause problems; 128K or lower is recommended.

    Hope this helps

    • Hey, I tried the recommended value of 32768 and it still gives the same recursion error when trying to debug.

      — commented June 23rd 2011 by Justin Toth

    • Justin, indeed, it is important to ensure that threadstacksize does not exceed the recommended value. However, to avoid deep recursion issues specifically, you should follow the advice in the link I provided.

      Thanks

    • I don't have "several levels of nested loops or recursive code", I don't even use recursion in this app. If it was an issue in my code then it would happen when not debugging too. The fact that it only happens when trying to debug implies an issue with the debugging feature.

      — commented June 24th 2011 by Justin Toth

    • I should also mention that I've seen other posts in this forum about seeing this issue when they were using 2-3 levels of subdirectories in their app, which is the case for me as well.

  • Are you using the MYAPP.os funciton/macro from the Tweetanium app? I had been using it in my mediaplayer file, but began getting too deep recursion errors on android. Once I shopped out to a playerview_ios.js and a playerview_android.js, I was fine. Check the file you're getting the error from and consider splitting the android and ios logic up into separate files. At Ti.include time, conditionally include ONLY the proper file.

    • I'm not using that. The file that it says has the recursion issue does have 9 include statements in it, however all 9 are needed in both Android andiOs so there's nothing I can do to slim that down.
