B4A Library Mock-LocationProvider Lib

Hi all,

I've written a small mock-locationProvider-library for B4A in java.

In this case I have to say thank You for all mates, who described the how to build a a4b-lib! - It was my second try of making an own lib in eclipse...
... and had great succes

If anyone is interested in further informations about my lib, let me know it.


regards

bitstra

Edit: uploaded library (1.0) with demo project

The demo code is well commented.


The moclocationprovider - library devlivers 3 public void() out of java-lib.
1. enableMockProvider(...)
2. publishMockLocation(............)
3. disableMockLocation(...)

If u test it, have a look to all comments in the sample procet code, about using the lib.
Also have look to code structure in ServiceModule (Timer_Tick), for calling publishMockLocation().

After using the sample you have to reboot your device, because my lib functions use the system GPS_PROVIDER name by android os.
!!!Without reboot the buildin gps-hardware can't deliver location data to the system!!!

bye

Yes, that was the mistake. Now, it runs:sign0060:

thanks....

Is there a simple way to convert the coordinates from the normal b4a-format to the mock_location-format? I have tried some things, but the mock_location provider ignores all my tested formats. Only a manually string like the example does work....

Thanks for help...

 

[Erel]

Can you post an example of the strings required?

 

[schimanski]

For example:

Latitude: 5134.5667
Longitude: 006.4574

These don't look like valid coordinates.

Location object from the GPS library allows you to change format between some of the common formats.

Hmmm, I have tried serveral things to change the normal decimal-coordinates to the following format, which I have to use for the mock-location provider, but I think, that are not decimal_degrees

latitude="5234.1421"        'lat. as decimal_degrees
longitude="01311.7996"        'long. as decimal_degrees

Has someone a sub to change the normal decimal-degree like 50.7478484 to the format above?

Thanks for help...

 

[bitstra]

Yes! here you go:

Here's how you convert latitude & longitude obtained from NMEA's GPGGA to decimal:

-------------/NMEA--------------/--------Decimal
latitude----/0302.78469 --------/-------03 + (02.78469/60) = 3.046412
longitude--/10141.82531-------/-------101 + 41.82531/60) = 101.6971


Notice that for latitude of 0302.78469,

03 ==> degress. counted as is

02.78469 ==> minutes. divide by 60 before adding to degrees above


Hence, the decimal equivalent is:
03 + (02.78469/60) = 3.046412



This way I convert the coordinates from NMEA Strings to dercimal in my GPS projects...

good luck

I forgot the divide by 60 before adding.:sign0148:

It works....:sign0060:

Hi this library works great but is it posssible to add one more thing to this library ? The number of satelites ? It could be usefuul

I'm in agree with you. This is a fantastic library and I'm using in my project, but I want to add more parameters like speed and satelites

How to convert gps location into the mock?

Sub GPSService_LocationChanged (Location1 As Location)
    Latitude = Location1.Latitude             ' 52.12345678
    Longitude  = Location1.Longitude        ' 25.12345678
End Sub

My issue is wrong format. The mock can't accept my GPS locations

 

[Andrei E]

or how to convert GPS values into the this mock?
example (18e Avenue lat: 45.562708 lon: -73.5948923)

Bump. Also struggling with this.

Hello

Try to use the example but when trying to execute the program, an error is reported that informs:

Hello

You both should create a new thread for any new question. Never post to existing threads.

Hello

Try to use the example but when trying to execute the program, an error is reported that informs:

"not allowed to perform MOCK_LOCATION"

- Are you sure that the DEVELOPER options are enabled on your device?
- Are you sure that in the developer options "Allow mock locations" is ENABLED?
- Are you sure that you've set the permission in your app adding

AddPermission(android.permission.ACCESS_MOCK_LOCATION)

inside the manifest editor?
- Have you set the target API to 16 (or below)? This is required by this library, as it's getting deprecated. Don't use it in production, as Google will force API 26 very very soon!

Please start a new thread, like Don said. I'll help you there.

Allow mock locations: ¿?

Yes, there's an option inside the developer options that looks like this
