android - Pasing data through app after install without launching -


refering this post need ask else.

i have application "a" download , install app "b".
want b "transfer" data a , a use data work.

i know can transfer data intent.
after installing b app a, android provide choice "ok" or "launch" ; question :

  • is possible pass data b a when click on "ok"? (so stay in a app without launching b)
  • if yes, how? possible "invisible" launch b? how should code b comportement?

i know might hard understand, can try check previous draw (here again).

edit:

i use code launch b installation a.

intent intent = new intent(intent.action_view); intent.setflags(intent.flag_activity_new_task); uri uri = uri.fromfile(new file(environment.getexternalstoragedirectory().tostring() + "/downloadedfile.apk")); intent.setdataandtype(uri, "application/vnd.android.package-archive"); getapplicationcontext().startactivity(intent);

there many ways handle this, here 1 (i believe) quite simple implement. since app [presumably] knows installing:

app a: add broadcastreceiver react installation, though default off.

android: broadcastreceiver on application install / uninstall

app b: add service background communication.

note: service must exported accessible other apps via explicit intent, creates security concern, open all other apps.

when user of app clicks install app b:

start broadcastreceiver filter set detect install: stackoverflow...android-broadcastreceiver-on-application-install-uninstall

app starts install.

when broadcastreceiver detects package has been added (the package name in received intent,) can stop broadcastreceiver, , can send explicit intent naming service in appb. can pass whatever data need in intent.

when appb service receives intent, can act in way you'd like.

service created using non-null intent, though 'action' of explicit intents null. service.onstartcommand() might receive null intent if service re-created.

i'd fill in more of code, have day job ;)

note:
intent.action_package_added called when package installed.
intent.action_package_install never used, , deprecated in api 14.
