I'm trying to take input from microphone and show that info in my edittext I have tried doing it in another activity it works fine but when I try to attach it with my login activity, as soon as it is done taking input from microphone my application crashes. On other activity it works fine it shows my input on my edittext but something is wrong with this activity and I can't find the solution

if (intent.resolveActivity(getPackageManager()) != null) {
startActivityForResult(intent, 10);
} else {
