Android Tutorial FusedLocationProvider + Resolution Dialog

Erel · Nov 24, 2019

** This is the only option to enable location services from inside your app. **

Example was updated and is based on B4XPages.
Don't miss:

1. ShowResolutionDialog sub that is added to Main. It needs to be added to the activity that hosts B4XPages.
2. #AdditionalJars in Main.
3. Manifest editor addition.

wich is the difference widht GPS module? and why we can use this library?
thank

Erel · Nov 25, 2019

FusedLocationProvider uses all kinds of location services to get the location including GPS, wifi data and others. It is more powerful and offer more options.

okay, so do you recommend replacing the GPS management with Fused Location?

Erel · Nov 25, 2019

It depends. If you are creating a new solution then use FLP. If you have an existing solution that meets your requirements then you will not gain much from switching.

Roberto P. · Nov 25, 2019

actually I have a management with GPS module that very often - especially in the office - has functioning problems because it cannot intercept the coordinates.
if you tell me that it is a more performing service, I value the replacement.

It is.

That's pretty fast indeed, but how to stop it from Main Activity in your example, and start it again, in order to have several activities that use it

Thanks

Erel · Nov 25, 2019

With the exception of the permission and the dialog everything happens in the starter service. It should be quite simple to control and use FLP from any other activity.

Delete your Android SDK and download a new one as explained here: https://www.b4x.com/b4a.html

Erel · May 10, 2021

Example was updated based on B4XPages. See first post.

josejad · May 10, 2021

Maybe it would be a good idea let the original example too, for people not using B4XPages yet?

Erel · May 10, 2021

Old example is attached.

Justcooldev · Dec 29, 2022

I am trying to use project.zip (FLP2) on several phones:

API 29: working
API 22 & 25: does not work (no results)

Do you know how I can fix the problem?

Thank you for your help.

Erel · Dec 30, 2022

More information please. What exactly happens? What do you see in your app? In the logs?

Justcooldev · Dec 30, 2022

Hi,

Thank you Erel for your help.

Here's what's going on with FusedLocationProvider (version 1.31) :

1) When launching the application :

LOGS :
Call B4XPages.GetManager.LogEvents = True to enable logging B4XPages events.
Connected to location provider

ON THE PHONE :
MainPage
Start
Location :N/A
State: N/A

2) when click start button :

LOGS :
State: Location enabled - waiting for updates

ON THE PHONE:
MainPage
Start
Location: N/A
State: Location enabled - waiting for updates

3) when click again on start button

LOGS and ON THE PHONE : the same as in point 2

Thank you

Erel · Dec 30, 2022

Looks fine. Test it outdoors.

Justcooldev · Dec 31, 2022

Hi Erel,
It's the same problem outdoors.
Thank you for your help.

Erel · Jan 1, 2023

It looks like it is unable to find the location. This is all that I can say. You can try this example: https://www.b4x.com/android/forum/t...t-not-firing-on-android-10.112140/post-699351
Might provider more information.
