Android Question UBER sdk

Has anyone integrated the UBER sdk into a B4a project?
If so, can you help get me started in doing so with mine?
Are there any libs that can be used?
All I want to be able to do is provide a "button" click access to UBER ride scheduling...
Thanks,
Rusty

Thanks Don,
...I have looked over all the UBER interface docs and since I don't "speak" java or Android Studio well, I've spent several hours trying.
I'm not familiar with how to use REST servers and okHTTPUtils...
Is there an example from which I can start?
BTW, I'm trying to integrate it within a B4a project, not B4j or anything else.
Regards,
Rusty

Thanks,
Does this mean the class can be modified to point to UBER instead of Dropbox?

Don,
Thanks for the advice.
For me, the Dropbox port was a failure...not your fault. :)
I'm trying to use the Java functions to get something going, but end up with:

          String uri =

          Intent intent = new Intent(Intent.ACTION_VIEW);
          intent.setData(Uri.parse(uri));

    }
#end if
Can someone advise me on what I'm doing wrong with this?
Thanks,
Rusty

There is no import for Packagemanager

Try to use Eclipse or android studio to see the needed imports to build the java you want to use

Thanks Don,
Unfortunately, Gradle nails me in my Android studio and i can get nowhere using studio...
I've tried using Uber's example code directly ... if I could control their IDE/environment I could probably follow your advice.
I have no idea how to see the needed imports...

In java each import much be available in the same file where an Object is used.
Look at the sample-code (java). At the top of each file you find all used imports

Thanks Erel,
It is giving me the error:
android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.intent.action.VIEW dat=uber://?action=setPickup&pickup=my_location&client_id=<Clientid>flg=0x20000 }
I have an activity running with a WebViewer1 embedded within the layout.
I'd like to use the WebViewer to "view" the intent results (which is an Uber webpage)

No.
The idea of the intent is to invoke a screen made available to users on UBER that doesn't require the app to be installed.
I have a client (a medical clinic with many patients) who wishes to allow their patients to use the tablet (when finished with it) to arrange a ride.
Each patient will need an account, but, once through booking the ride, the account information, name etc. must be destroyed.
My approach is to use their web interface without installing UBER.
I can invoke the installed intent already, but wish to use the webview to do the above.
Thanks for your continued support

i´m not sure you are right.

The code you posted searches for the uber app and start an intent to this app. Whatever this app may show...
it is not a website you can show inside your app.

In fact you want to start the Uber app with the code.
And it is the Uber app which shows something after it got started...

You know you can check the existence of the Uber app with the B4A Pakagemanager?
Use the PM. check for the app. If it does not exist you point the user to show the webpage
B4X:
 String url = "https://m.uber.com/sign-up?client_id=<CLIENT_ID>";
