No matter what app I write, upon running on my mobiles (Nexus 5 and Note 2), I see errors. It is expected to be a bug in Android Studio.
Detailed explanation: I created two new projects. One with blank activity and one with blank activity+Fragment. Didn't edit anything and tap on Run. Gradle build was successful. It was installed on my device. But when I opened the app on my device, It said "Unfortunately [app name] has stopped."

I dug a few similar issues on stackoverflow. One of them pointed to App's theme. I changed that too. But this shouldn't be the issue as Yesterday when I created a blank app. It ran and showed "Hello world" on my phone.
Also, I uninstalled and re-installed Android Studio (saved SDk to another folder), But that also didn't resolve the issue.
Please help me out someone :/ :(
