Where is the warnings screen option in Android Studio?

Solution 1:

If, on the toolbar, you click Analyze -> Inspect Code; then in the window that pops up select how much of your project you want to inspect (I usually do Whole Project, but you might want to select a specific module), then click okay.

Android Studio will work for a bit, then the inspection window will pop up from the bottom with a list of results, subdivided by inspection.

Solution 2:

Build -> Make Project (Ctrl + F9) gives what we can get equivalent of Eclipse's “Problems” view on Android Studio

Solution 3:

you can use F2 to next problems, see more here: Navigating to Next/Previous Error

Solution 4:

GO to View-->Tool Windows-->Messages to view the warnings
