Comment on attachment 8853828 [details] Bug 1351556 - Collect information on the number of users using PWA. https://reviewboard.mozilla.org/r/125464/#review128460 I don't think onCreate() is sufficient. We might be re-using an already existing instance and just go through onNewIntent() and load a new webapp without re-creating the activity. I flagged dale as additional reviewer, he can help with finding all entry points.

Hi Joe I thought we just need the count of distinct users. So the count of activity launch should be enough. Is that correct?

Comment on attachment 8853828 [details] Bug 1351556 - Collect information on the number of users using PWA. As Sebastian said, but will expand a little. If we want to count how many times an app is launched from the homescreen, onCreate will capture most cases, however there are times when running multiple apps that an activity may get reused by seperate apps, so we would need to capture that within http://searchfox.org/mozilla-central/source/mobile/android/base/java/org/mozilla/gecko/webapps/WebAppActivity.java#142

it looks like it's resolved but what i have in mind on what we want to learn initially are - Collect information on the number of Firefox launches using PWA standalone mode - Collect information on the number of progressive web apps that’s added to homescreen - Collect information on the number of users using PWA

Joe, what is our definition of PWA? Web properties having a manifest link?

What I have in mind regarding these is that we want to know if users are using the standalone mode (e.g. after adding an icon to the homescreen and repeatedly using it as an app) instead of just usage as users come across web properties having a manifest during regular browsing. - Collect information on the number of Firefox launches using PWA standalone mode - Collect information on the number of users using PWA
