    Solve android runtime

    lifecycle: runtime: 1. To solve could not find runtime aar, I just simply arranged the google( ) on top in repositories. setText( currentQ. getQUESTION( ) ) ;. where is your get Question class? it seems to me in there you are calling getDatabase method ( perhaps through your dbHelper) recursively. as it clearly says on Log: Caused by:. This error is caused when Android Studio can' t generate your R. java file correctly, and it can often crop up. If you need to use variations of the same image, then use the same base image and customize it at runtime, rather than adding multiple versions of the same image to your project. If this is the case, then resolving these errors should solve the ActivityNotFoundException, lect the android tab at the bottom. On the top right corner of that window, there is a tiny icon that shows an android behind a gear. That button is " restore android logcat". That shows the trace. Android studio is a terribly.

    Please post your MainActivity file as well. But looking at the error what I can assume is this. You are instantiating some view. Let' s say a TextView. And this is ur code. public class MainActivity extends Activity { TextView. NullPointerException: Attempt to invoke virtual method ' void android. FloatingActionButton. setOnClickListener( android. View$ OnClickListener) ' on a null object reference at android. w when you know what is the exception and where it happens, you should be able to solve it! In LogCat you will find among all those run time errors there is a tag " Caused by" under text attribute. you will click the next line.
