Hello Did you rebuild entirely your project ? Did you check your app need multidex ?

We have several examples that run perfectly in 17
check the Todo app
for example

[jlberrocal]

Yes i rebuild my entire project with no positive results, multidex was enabled

with other DI library i had to change the Application class to MultiDexApplication and it worked, i don't know if the same fix apply for your library

[arnaudgiuliani]

Yes, try to change your supertype from Application to MultiDexApplication
