SDK 4.10.0: java.lang.IllegalStateException: Timer was canceled

[gsams04]

Hi,

We recently upgraded to 4.10.0 from 4.4.0 and we've received multiple reports of this crash

java.lang.IllegalStateException: Timer was canceled

We haven't personally seen this issue but this happens in all OS versions starting Lollipop.

If it's of any help, here's how we initialize Tune.

Tune.init(app,tune_advertiser_id,tune_converion_key );
Tune.getInstance().setShouldAutoCollectDeviceLocation(false);

What could've possibly been the problem?

Thanks for the help.

Hi @gsams04, it looks like a timing issue when the timer is canceled by setShouldAutoCollectDeviceLocation soon after init.

A better way to disabling location collection is to use the TuneConfiguration option in init:

TuneConfiguration tuneConfig = new TuneConfiguration();
tuneConfig.setShouldAutoCollectDeviceLocation(false);

Tune.init(this, "your_advertiser_id", "your_conversion_key", false, tuneConfig);

I will create a ticket to make setShouldAutoCollectDeviceLocation more thread-safe.
