Updating from 4.3.0 to 4.5.0 causes crashes when rotating

[jt-gilkeson]

Updated from 4.3.0 to 4.5.0 and we see the following crash when rotating the phone. (If I simply change back to 4.3.0 with no code changes the crash doesn't happen).

Hi @jt-gilkeson, 4.4.0 updated our v4-support library versions to v24. Could this be affecting your v4 classes?

[jt-gilkeson]

Not sure, we are using Support Lib 23.4.0.

24.x causes some breaking changes in play services, so we haven't had time to update to it yet.

[jt-gilkeson]

It looks like this may have solved the issue for me:

   compile('com.tune:tune-marketing-console-sdk:4.5.0') {
        exclude module: 'support-v4'
    }

[john-gu]

Great, glad to hear you found a fix! I'll close this out for now, please let us know if you have issues when you do update to v24.
