Why is my app crashing when I try to open a Navigation Drawer Activity from an Empty Activity?

Question

I am a beginner in android My app starts with a Splash Screen which goes to an Empty Activity where it takes some info. It works fine till here. After that I used a submit button to guide the user to the Navigation drawer activity, but somehow the app crashes. I tried to replace the navigation drawer activity with an Empty activity on button click, which worked fine. I also tried launching the navigation drawer activity from splash screen, didn't work as well.

submitButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent gotoChoiceSelection = new Intent(getApplicationContext(), ChoiceSelection.class);
            startActivity(gotoChoiceSelection);
        }
    });

(ChoiceSelection is my Navigation drawer activity)

if you are using a activity to Navigation drawer activity

you can try this in the place of getApplicationContext()

I think you should change your java code like this:

submitButton.setOnClickListener(new View.OnClickListener() {
@Override
  public void onClick(View v) {
  Intent gotoChoiceSelection = new Intent(this, ChoiceSelection.class);
            startActivity(gotoChoiceSelection );
 }
});

Putting this gives me an error. I tried MainActivity.this also instead of getApplicationContext(). It still doesn't work. – Abhi Aug 09 '18 at 15:25
can you post your full java code? – karthik Aug 09 '18 at 15:28

Try this code, it worked for me:

submitButton.setOnClickListener(new View.OnClickListener() {
   @Override
    public void onClick(View v) {
    Intent gotoChoiceSelection = new Intent(this, ChoiceSelection.class);
        startActivity(gotoChoiceSelection );
 }
});

Just replace getApplicationContext() with this.

Why is my app crashing when I try to open a Navigation Drawer Activity from an Empty Activity?
