First of all, check the window "Edit Configuration" that opens when you click in "Run" or "Debug" button.
Then, check the bottom section "Before launch: Gradle-aware Make". Click on that small triangle to hide it. An error message should appear. This message should give you a clue about your problem. In my case this message says: "Error: Default Activity not found", that's because I was changed my
<category android:name="android.intent.category.LAUNCHER" />
for
<category android:name="android.intent.category.DEFAULT" />

Hope this help you or somebody. Sorry for the english. ;)
