Java.lang.IllegalStateException: Already attached

Question

I'm trying to build an app, that pastes an input from a previous activity(works with no problem) and then shows me some things from a database(when ButtonGet is pressed). The problem is that when I try to Run the project, I get Java.lang.IllegalStateException: Already attached. What is wrong with my code?

Solution

In your onCreate, you're calling super.onCreate() twice, and also setContentView() twice. I'm pretty sure that's not what you want to do.

If you are ever seeing a crash, be sure to post the stack trace in logcat when stating your question.

[Gabe Sechan]

Its probably the super call. Calling setContentView twice is pointless in a single function, but is totally legal overall.

After removing the super.onCreate, I get this AppCompat does not support the current theme features. Although I have the theme instaled

[user3026270]

Now I get, java.lang.NullPointerException

This should really be a comment.

I took out the duplicates, and now I get , java.lang.NullPointerException

[Chintan Desai]

is it your final code of activity from where you call the DB class. If it is you haven't initialize your db yet please first initialize it. If possible please paste your erroneous onCreate method of Second activity as well.

[Doug Stevenson]

@user3026270 now it sounds like you have a completely unrelated problem which could now be its own question.

[user3026270]

I init the DB in a different class. And what do u mean by "paste your erroneous onCreate method of Second activity as well".

[Chintan Desai]

I saw your logcat error message it says error on line 58 of second activity.

[Doug Stevenson]

@user3026270 if you found this answer to be helpful, please accept it as the correct answer and follow up with different questions in another question.

[Surya Tej]

Thanks, my code had the super.onCreate method defined at multiple instances, and your solution solved mine
