since this is not working,right now i'm adding java class,xml file then linking them together.is there a solution for this???

Edit-- Currently my project doesn't have any code(apart from default generated activity_main.xml and MainActivity.java) so there has to be an IDE error. This was caused when i tried to add new Activity to my project(by right click on project>new>Activity>EmptyActivity) and also this error is being shown in every project i opened(in the IDE error logs at the bottom right corner). i tried invalidate and restart it didnt work any solutions??

    add some code/.. – Amit Vaghela Apr 07 '17 at 10:31
  • @Rotwang, I don't believe your edit is fully correct, the `android-studio` tag was necessary since the exception come from the IDE, not his project. So in fact, the duplicate won't help either since he can't debug it ;) Please add the android-version you are using – AxelH Apr 07 '17 at 11:02
  • @AxelH I highly soubt that they released a faulty IDE which causes NPEs... after forcing a bazillion users to leave Eclipse!! But I could be wrong. – Phantômaxx Apr 07 '17 at 11:05
  • @Rotwang Well, the source of the exception [`com.android.tools.idea.actions.NewAndroidComponentAction.actionPerformed`](https://android.googlesource.com/platform/tools/adt/idea/+/master/android/src/com/android/tools/idea/actions/NewAndroidComponentAction.java) is a class of android studio, so a bug can happen, of course this is based on some specific case, so I bet if OP reinstall the same version, it will work fine. But hard to say since the current version as been updated. – AxelH Apr 07 '17 at 11:10
  • @Rotwang Any solution??? – vishal bhati Apr 08 '17 at 14:19
  • Find the object you are using before having it instanced. – Phantômaxx Apr 08 '17 at 14:20
  • @Rotwang http://stackoverflow.com/questions/42102456/android-studio-2-2-3-crashes-whenever-i-create-a-new-activity i have the same problem ....its not about the code its IDE error – vishal bhati Apr 08 '17 at 14:34
  • @AxelH do you face the same problem while adding a new activity??? – vishal bhati Apr 08 '17 at 17:59
  • @vishalbhati No... and you seems to be one of few to have it. Please add the android-studio version (build) – AxelH Apr 09 '17 at 17:40
  • @AxelH Android studio 2.3.1,Build number-"AI-162.3871768",Android sdk tools-25.2.5,Android platform version-API 25:Android 7.1.1(Nougat) revision 3,JRE-1.8.0_112,JVM:open JDK 64bit Server VM byJetBrains.btw did you check out the above link coz i have the exact same problem – vishal bhati Apr 10 '17 at 15:55
