Embedded library cannot be found

[percula]

For the android-mobile todo example, I am experiencing the following exception upon build (without changing anything):

Hi my friend, have you found an answer for your problem, I've encountered the same one ?

[percula]

@YovoManolov , I believe it is because we need to initialize the app client. See this other issue I created: mongodb/stitch-android-sdk#85 (comment)

Unfortunately I haven't had time to test this yet.

Just in case anyone comes across this in the future, the issue here is likely that the Android emulator that you're using is set to x86 rather than x86_64. I ran into this issue and after changing the emulator settings it worked fine.
