J2ME GPS - half solution

[kiu112]

I recently bought an A780 (german version) and tried to access the JSR-179 Location API.

I got it working, but ONLY if copilot software is running as a background process! The J2ME API returns correct location information, but seems to be unable to activate/synchronize the GPS. Thats currently the job of copilot in the background.

Not a nice solution, but enough to play with it

To access/compile Location API you need to include this lib into your project:
C:\Programme\Motorola\SDK v5.2.1 for J2ME\EmulatorA.3\lib\stubclasses.zip

Code example:
// init
Criteria c = new Criteria();
c.setPreferredPowerConsumption(Criteria.POWER_USAGE_HIGH);
LocationProvider lp = LocationProvider.getInstance(c);

// automatic update of location
lp.setLocationListener(this, 5, 5, 5);

OR

// manual request
Location l = lp.getLocation(5);
OR
Location l = LocationProvider.getLastKnownLocation();

QualifiedCoordinates qc = l.getQualifiedCoordinates();
qc.getLatitude();
qc.getLongitude();
qc.getAltitude();

Happy hacking!

lapisrv is the GPS Location API Service on A780, seems it will be up when run CoPilot.

Have you tried to use MOTO's J2ME Location API?
import com.motorola.location.*;

A program (with source file) which uses it can be found from:
http://per.nitro.dk/

Where to find motorola location package com.motorola.location.* :

Motos Location API is not included in the SDK download. No way to access it

I am too dumb to read your post

Sorry, trying the moto api soon

[kiu112]

The result using Motos Location API from the A925 is as expected, immediate crash while starting the app on the phone. In the source nothing is done, except GUI stuff. Probably it didnt like the imports...

Moto Location API ws locked by motorola like another special API. they need Moto certificated file to make it work.

But sime guy at ccmove can make it work by replaced a permfile.txt after install midlet.

I was try to create midlet to access file system. Midlet cant start until i replace a new permfile.txt. Could you try this permfile.txt with your gps midlet?

[kiu112]

The permfile looks like the one included with the snowboard game.
After replacing my permfile with yours there are no differences, still immediate crash

May be this permfile.txt is for Moto file access API only. so we still looking for permfile.txt for Location API.

I can not access the location API on my A780, also not if Copilot runs in the backround. I tried also to replace the Permfile witout success. Is there any solution to run GPS-midletes on the A780?
