title: opening google map fragment on button click in android studio
body: <p>I would like to create an app in Android Studio that has a Button in Main Activity and when i clicks this button, it should open a google map with my customized lat,lng markers and camera functions as an another activity. I tried this one by creating a Button in the Main Activity.XML and wrote buttonOnClickListener() by specifying Intent that MainActivity.this,Mapfragment.class.For this I selected GoogleMaps as my start Activity instead of blank activity at starting of my project. And also for this MapFragment, I got Google maps API key. But when I run this App on my android mobile, it simply opening google map with my customized lat,lng instead of showing my Main Activity which is having a Button in it. I am confused with this, can anyone help me out of this problem.Thank You </p>
