this question has already been asked here How to install applications programmatically without opening Play Store (as Google Drive does) but I want to know how it works

I am supposed to write this code: 

Intent intent = new Intent("com.android.vending.billing.PURCHASE");
intent.setClassName("com.android.vending","com.google.android.finsky.billing.lightpurchase.LightPurchaseFlowActivity");
intent.putExtra(EXTRA_NAME, EXTRA_VALUE);
startActivityForResult(intent, 0);

So what should be in this line: intent.putExtra(EXTRA_NAME, EXTRA_VALUE);

and how it's getting another app without opening play store

  • If you read the answer from which you pulled this code, you will find that it has: "However, calling LightPurchaseFlowActivity from non-Google signed app is failing, because they are, again apparently (according to the logs), checking the calling package's signature... this can not be achieved at this moment". – CommonsWare Sep 13 '15 at 16:30
  • Did you get it to work? – אVי Apr 30 '19 at 19:39
