Unable to capture screenshot. Caused by: java.lang.IllegalArgumentException: width and height must be > 0

Hi guys,

I'm using:
classpath 'com.stanfy.spoon:spoon-gradle-plugin:1.2.2'
androidTestCompile 'com.squareup.spoon:spoon-client:1.6.4'
and I keep getting this crash (3 out 5 times) .

This is how I capture screenshots;
Spoon.screenshot(solo.getCurrentActivity(), "Screenshot_" + getTime());

Do you have any recommendation how to avoid this crash?
Cheers to all.

Hi @sika78,

Could you post a snippet of how you run the test?

I've encountered similar error when Espresso Rule was set to NOT autostart the activity.
Taking a screenshot while expected activity is not running would either show the width error or null pointer exception.
