确定应用程序是否已安装在android上

Question

On my android phone I launch an standard browser, after enter my URL www.example.com and press open. I need some ways to determine if I have installed on my phone for example MYAPP, must I write an plugin for my Android browser or may be I must add some java functionality to my web site or maybe something else ?

I need some information, articles or something else of how can I do that, every kind of information will be helpful.

Answer 1

@Aleks G is correct, you cannot do this. However, you can make your app so that it will open when your web page is opened, given that it is already installed.

See here: Launch custom android application from android browser

Answer 2

- I don't think that what you want to do is possible...

- Yet you can use BroadCast-Receiver to determine when you browser opened and then you can launch your app if its installed..

- Another way to manually check, that whether you app has been installed or not, please check the Manage Application from Application , under Setting .
