updateLayout crashes android

You must Login before you can answer or comment on any questions.

Hi all,

I have created an app and on iPhone it works just fine, but on android it crashes without an error or mentioning in the debug or log. I removed in my API the updatelayout and it does not crash anymore on Android ( versions 2.3.3 , 4.0.3, 4.1) Can anyone explain? Using Titanium 2.1.2, 2.1.3 and 3.0.0.

Cheers, Carlo

  • We are seeing the same issue. If I comment out all the calls to updateLayout, the crash goes away.

  • The same thing happens with my app! Still searching for answers.

  • I haven't found any solutions for this. It works in my simple example app, but not in my "real" app. It seems to be a timing issue of some sort.

    Maybe for that reason, updateLayout() is deprecated in the CI build for 3.0.0. The CI build for 3.0.0 has a new function, applyProperties(), which seems to work on Android!

@Kevin,

I believe so indeed. Am using now SDK 3.0 with applyProperties and it works like a charm.
