Thanks for great work. I face a strange issue that I can't install my app on same device that have your demo app.

After investigation, I found this stack overflow link:
http://stackoverflow.com/questions/16267785/install-shows-error-in-console-install-failed-conflicting-provider

Because your library manifest has provider with:
android:authorities="br.com.mauker.materialsearchview.searchhistorydatabase"

because this value should be unicque, every device will have one app only that uses MaterialSearchView
