Can anybody please guide me regarding how to launch my android application from the android browser

User · Answer

Please see my comment here  Make a link in the Android browser start up my app   We strongly discourage people from using their own schemes  unless they are defining a new world-wide internet scheme

Please note if your icon is disappear from android launcher when you implement this feature  than you have to split intent-filter        lt activity         android name   MainActivity          android label   string app name   gt           lt intent-filter gt               lt action android name  android intent action MAIN    gt               lt category android name  android intent category LAUNCHER    gt           lt  intent-filter gt           lt intent-filter gt               lt action android name  android intent action VIEW    gt               lt category android name  android intent category DEFAULT    gt               lt category android name  android intent category BROWSABLE    gt               lt data android scheme  your-own-uri    gt           lt  intent-filter gt       lt  activity gt

All above answers didn t work for me with CHROME as of 28 Jan 2014  my App launched properly from http   example com someresource  links from apps like hangouts  gmail etc but not from within chrome browser   to solve this  so that it launches properly from CHROME you have to set intent filter like this    lt intent-filter gt       lt action android name  android intent action VIEW    gt        lt category android name  android intent category DEFAULT    gt       lt category android name  android intent category BROWSABLE    gt        lt data         android host  example com          android pathPrefix   someresource           android scheme  http    gt       lt data         android host  www example com          android pathPrefix   someresource           android scheme  http    gt   lt  intent-filter gt    note the pathPrefix element  your app will now appear inside activity picker whenever user requests http   example com someresource  pattern from chrome browser by clicking a link from google search results or any other website

For example  You have next things   A link to open your app  http   example com   The package name of your app  com example mypackage  Then you need to do next   Add an intent filter to your Activity  Can be any activity you want  For more info check the documentation    lt activity      android name  quot  MainActivity quot  gt         lt intent-filter android label  quot  string filter title view app from web quot  gt            lt action android name  quot android intent action VIEW quot    gt            lt category android name  quot android intent category DEFAULT quot    gt            lt category android name  quot android intent category BROWSABLE quot    gt            lt  -- Accepts URIs that begin with  quot http   example com quot  -- gt             lt data              android host  quot example com quot               android scheme  quot http quot    gt        lt  intent-filter gt         lt intent-filter gt            lt action android name  quot android intent action MAIN quot    gt            lt category android name  quot android intent category LAUNCHER quot    gt        lt  intent-filter gt     lt  activity gt     Create a HTML file to test the link or use this methods  Open your Activity directly  just open your Activity  without a choosing dialog    Open this link with browser or your programm  by choosing dialog    Use Mobile Chrome to test  That s it    And its not necessary to publish app in market to test deep linking    Also  for more information  check documentation and useful presentation

In my case I had to set two categories for the  lt intent-filter gt  and then it worked    lt intent-filter gt   lt data android scheme  my special scheme    gt   lt action android name  android intent action VIEW    gt   lt category android name  android intent category DEFAULT   gt   lt category android name  android intent category BROWSABLE   gt   lt  intent-filter gt

Look  JRuns answer in here  The idea is to create html with your custom scheme and upload it somewhere  Then if you click on your custom link on your html-file  you will be redirected to your app  I used this article for android  But dont forget to set full name Name    MyApp Mobile Droid MainActivity  attribute to your target activity

User · Answer

Yeah  Chrome searches instead of looking for scheme  If you want to launch your App through URI scheme  use this cool utility App on the Play store  It saved my day    https   play google com store apps details id com naosim urlschemesender

User · Answer

Hey I got the solution  I did not set the category as  Default   Also I was using the Main activity for the intent Data  Now i am using a different activity for the intent data  Thanks for the help

Use an  lt intent-filter gt  with a  lt data gt  element  For example  to handle all links to twitter com  you d put this inside your  lt activity gt  in your AndroidManifest xml    lt intent-filter gt       lt data android scheme  http  android host  twitter com   gt       lt action android name  android intent action VIEW    gt   lt  intent-filter gt    Then  when the user clicks on a link to twitter in the browser  they will be asked what application to use in order to complete the action  the browser or your application   Of course  if you want to provide tight integration between your website and your app  you can define your own scheme    lt intent-filter gt       lt data android scheme  my special scheme    gt       lt action android name  android intent action VIEW    gt   lt  intent-filter gt    Then  in your web app you can put links like    lt a href  my special scheme   other parameters here  gt    And when the user clicks it  your app will be launched automatically  because it will probably be the only one that can handle my special scheme    type of uris   The only downside to this is that if the user doesn t have the app installed  they ll get a nasty error  And I m not sure there s any way to check     Edit  To answer your question  you can use getIntent   getData   which returns a Uri object  You can then use Uri   methods to extract the data you need  For example  let s say the user clicked on a link to http   twitter com status 1234   Uri data   getIntent   getData    String scheme   data getScheme        http  String host   data getHost        twitter com  List lt String gt  params   data getPathSegments    String first   params get 0       status  String second   params get 1       1234    You can do the above anywhere in your Activity  but you re probably going to want to do it in onCreate    You can also use params size   to get the number of path segments in the Uri  Look to javadoc or the android developer website for other Uri methods you can use to extract specific parts

You need to add a pseudo-hostname to the CALLBACK URL   app     doesn t make sense as a URL and cannot be parsed

Felix s approach to handling deep links is the typical approach to handling deep links  I would also suggest checking out this library to handle the routing and parsing of your deep links   https   github com airbnb DeepLinkDispatch  You can use annotations to register your Activity for a particular deep link URI  and it will extract out the parameters for you without having to do the usual rigmarole of getting the path segments  matching it  etc  You could simply annotate and activity like this    DeepLink  somePath  someParameter1   someParameter2    public class MainActivity extends Activity

There should also be  lt category android name  android intent category BROWSABLE   gt  added to the intent filter to make the activity recognized properly from the link

The following link gives information on launching the app  if installed  directly from browser  Otherwise it directly opens up the app in play store so that user can seamlessly download   https   developer chrome com multidevice android intents

Xamarin port of Felix s answer  In your MainActivity  add this  docs  Android App IntentFilterAttribute Class          IntentFilter new          Intent ActionView         Categories   new     Intent CategoryDefault  Intent CategoryBrowsable         DataScheme    my special scheme     public class MainActivity   Activity              Xamarin will add following in the AndroidManifest xml for you    lt activity     android label  Something      android screenOrientation  portrait      android theme   style MyTheme      android name  blah MainActivity  gt       lt intent-filter gt           lt action android name  android intent action VIEW    gt           lt category android name  android intent category DEFAULT    gt           lt category android name  android intent category BROWSABLE    gt           lt data android scheme  my special scheme    gt       lt  intent-filter gt   lt  activity gt    And in order to get params  I tested in OnCreate of MainActivity    var data   Intent Data  if  data    null        var scheme   data Scheme      var host   data Host      var args   data PathSegments       if  args Count  gt  0                var first   args 0           var second   args 1                         As far as I know  above can be added in any activity  not only MainActivity  Notes    When user click on the link  Android OS relaunch your app  kill prev instance  if any  and run new one   means the OnCreate event of app s MainLauncher Activity will be fired again  With this link   lt a href  my special scheme   host arg1 arg2  gt   in above last code snippet values will be    scheme  my special scheme host  host args    arg1    arg2   first  arg1 second  arg2   Update  if android creates new instance of your app  you should add android launchMode  singleTask  too
