Launch Mode Singletop not working with permisison dialog showing

Question

I have an Activity with launch mode singleTop which shows permission dialog.

But when permission dialog is present and a new Intent comes for that activity , another instance is created . onNewIntent() doesn't get called.

Any workaround for this?

Below is the manifest entry.

<activity
        android:name=".auth.activity.AJRAuthActivity"
        android:screenOrientation="portrait"
        android:theme="@style/Theme.PageIndicatorDefaults"
        android:launchMode="singleTop"
        android:windowSoftInputMode="adjustResize" />

The way I start this activity:

Intent loginIntent = new Intent(context, AJRAuthActivity.class);
context.startActivity(loginIntent);

Can you add the launchMode to your calling intent as well: `loginIntent.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);` — Christopher, Apr 20 '18 at 08:00
try to request it in `onStart` and check if it behaves correctly. It worked for me previously — Sagar, Apr 20 '18 at 13:32

Showing the permission dialog usually starts another Activity (a system Activity) on top of your Activity. In this case, your Activity will be paused (onPause() is called). At that point, your Activity is no longer the top Activity on the stack, so that another launch of the Activity will create another instance, even if "singleTop" launch mode and/or Intent.FLAG_ACTIVITY_SINGLE_TOP is specified.

To get around this, you should ensure that you have all the permissions that you might need as early as possible, or rearchitect your application so that you don't have the problem of multiple instances.
