How do I close an external app like Instagram launched from my app and return to the Triggering App?

I have an Android App which uses Intent to launch Instagram, to my page. Once the user is done with Instagram and closes it with the back arrow, I need instagram to close and return the user back to my Android App which triggered the activity. my Intent works and opens instagram but with the back button it stays in instagram. Find below my code triggering instgram

public void LaunchInstgram(View view) Intent openInstagram = getPackageManager().getLaunchIntentForPackage("com.instagram.android"); openInstagram.setData( Uri.parse( "https://www.instagram.com/_u/eatoutlagos") ); try startActivity(openInstagram); catch (ActivityNotFoundException e) Toast.makeText(this, "Sorry, Instagram Not Installed", Toast.LENGTH_LONG).show();

I think you are calling finish() method in you MainActivity before starting Instagram App via Intents

finish()

MainActivity

Instagram

Intents

The scenario which you have described will occur in following two ways:

EITHER

You have set android:noHistory = "true" for MainActivity inside AndroidManifest.xml which causes MainActivity to finish automatically on pressing the back key.

android:noHistory = "true"

MainActivity

AndroidManifest.xml

MainActivity

Before switching to your LaunchInstragram, you have called finish() in your MainActivity, which kills it. When you press back button,since no other activity is present in stack to pop, it stays there...

LaunchInstragram

finish()

Also you could try ChatHeads on you App by clicking the following link

EDIT

try the following code :

Uri uri = Uri.parse("https://www.instagram.com/_u/eatoutlagos"); Intent likeIng = new Intent(Intent.ACTION_VIEW, uri); likeIng.setPackage("com.instagram.android"); try startActivity(likeIng); catch (ActivityNotFoundException e) startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("https://www.instagram.com/_u/eatoutlagos")));

thanks Amit, let me try out the options

hi Amit, I dont seem to be able to get the first two options working. At which stage in my mainActivity do i put the finish() method? If i put it in the onCreate method it doesnt start the activity at all when i click the button to start. I put it in the method that launches the instagram intent and there is not change, instagram still doesnt close back to my app

public void LaunchInstgram(View view){ finish(); Intent openInstagram = getPackageManager().getLaunchIntentForPackage("com.instagram.android"); openInstagram.setData( Uri.parse( "instagram.com/_u/eatoutlagos") ); try startActivity(openInstagram); catch (ActivityNotFoundException e) { Toast.makeText(this, "Sorry, Instagram Not Installed", Toast.LENGTH_LONG).show(); //startActivity(new Intent(Intent.ACTION_VIEW,Uri.parse("instagram.com/eatoutlagos"

in the second case I have put the command in the manifest file within the activity that launches the Intagram app as below <activity android:name=".ContactUs" android:noHistory = "true"/>
