如何从Android中的主应用访问模块？

Question

I have a main Android App, called A and a module called B. I have imported the module and added the correct dependencies. My question is: how do I actually use the information from the module inside my Android App? Do I just do B b = new B(); inside A? I think that this method is more related to accessing other classes within the same module. Is there a specific way to access modules that is different from accessing other classes within the same module?

Answer 1

Am assuming your modules are Java Classes, just instantiate them the way you are proposing
b = new B();

If those modules are Android UI elements like Activities/Fragments etc then you have pass an Intent to start them. Refer to Android documentation here

 Intent intent = new Intent(this, YourActivityB.class);
 EditText editText = (EditText) findViewById(R.id.editText);
 String message = editText.getText().toString();
 intent.putExtra(EXTRA_MESSAGE, message);
 startActivity(intent);

Similarly for an Android service (documentation here ):-

Intent intent = new Intent(this, HelloService.class);
startService(intent);
