Question

Launching a specific browser by icon is done with a ACTION_MAIN.
Launching a specific url using default browser is done with a ACTION_VIEW.

What if you want to open a specific url in a specific browser?

Answer 1

If you know the package name and the class name of the browser,you can use
Intent.setClassName (String packageName, String className). looks like:

Intent i=new Intent(ACTION_VIEW, url);
i.setClassName("com.test.browser","BrowserActivity");
startActivity(i);
