title: how can Android App A bring front the form of Android B by the click of a Button from Android A
body: <p>I want to do a POC in which I want to bring up a form display of Android app B by clicking a button from Android App A i.e it must bring up/bring the form or Activity or a  display of Android App B to the front and after that when user is Clicking a button say "minimize" it  must minimize the display (or go back to forground )of Android app B and bring back the display of Android app A (Both Android  app A and B will be on the same device) </p>
  
  <p>I am not looking a solution to open the App B but purely to bring up the form of Android app  B assuming if the Android B app is running in the background on the same device </p>
