Dagger2 crashing on startup for Android 4.x

[haseebrabbani]

Hi there! I just started using Dagger2 in my Android app. The app works just fine on Android 5.x devices, but crashes on startup on Android 4.x devices. I am testing this on my debug build where Proguard is NOT enabled. Any thoughts would be appreciated. Here is the stacktrace:

@haseebrabbani it's MultiDex problem.

[haseebrabbani]

@artem-zinnatullin thanks for the tip! Are there any solutions you could recommend?

[haseebrabbani]

It was in fact a multi-dex issue. My application class did not extend MultiDexApplication (even though I had enabled multidex in my build.gradle).

@haseebrabbani glad that you've fixed it! Sorry that I didn't provide the solution, I was sleeping, interrupted by notification, wrote short answer and continued seeing dreams about software development :)
