Try this: Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse(“http://www.google.com”)); startActivity(browserIntent); That works fine for me. As for the missing “http://” I’d just do something like this: if (!url.startsWith(“http://”) && !url.startsWith(“https://”)) url = “http://” + url; I would also probably pre-populate your EditText that the user is typing a URL in with “http://”.
If you want the display dimensions in pixels you can use getSize: Display display = getWindowManager().getDefaultDisplay(); Point size = new Point(); display.getSize(size); int width = size.x; int height = size.y; If you’re not in an Activity you can get the default Display via WINDOW_SERVICE: WindowManager wm = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE); Display display = wm.getDefaultDisplay(); If you … Read more

Putting it simply: As the name suggests, it’s the context of the current state of the application/object. It lets newly-created objects understand what has been going on. Typically you call it to get information regarding another part of your program (activity and package/application). You can get the context by invoking getApplicationContext(), getContext(), getBaseContext() or this … Read more
I’m assuming you’re using XML layout. <TextView android:layout_width=”match_parent” android:layout_height=”match_parent” android:gravity=”center” android:text=”@string/**yourtextstring**” /> You can also use gravity center_vertical or center_horizontal according to your need. As @stealthcopter commented, in java: .setGravity(Gravity.CENTER);. And for Kotlin users, .gravity = Gravity.CENTER
You need to override onSaveInstanceState(Bundle savedInstanceState) and write the application state values you want to change to the Bundle parameter like this: @Override public void onSaveInstanceState(Bundle savedInstanceState) { super.onSaveInstanceState(savedInstanceState); // Save UI state changes to the savedInstanceState. // This bundle will be passed to onCreate if the process is // killed and restarted. savedInstanceState.putBoolean(“MyBoolean”, true); … Read more
