title: Converting project as a library
body: <p>I've made a basic project for custom toast. Now I want that project to work as a library in my future projects. How do I convert my project into a library?
  P.S: This is just a dummy project so that I can learn how to create libraries of my own. 
  The code is as follows:</p>
  
  <pre><code>public class CustomActivity extends Activity {
  
  @Override
  protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_custom);
  
      Button btn = (Button) findViewById(R.id.button1);
      btn.setOnClickListener(new View.OnClickListener() {
          public void onClick(View v) {
              LayoutInflater inflater = getLayoutInflater();
              View layout = inflater.inflate(R.layout.toast_custom_layout,
                      (ViewGroup) findViewById(R.id.toast_layout_root));
  
              Toast toast = new Toast(getApplicationContext());
              toast.setGravity(Gravity.BOTTOM, 0, 0);
              toast.setDuration(Toast.LENGTH_LONG);
              toast.setView(layout);
              toast.show();
  
  
          }
      });
  
  }
  </code></pre>
  
  <p>}</p>
