how to get GPS lcoation accuracy in j2me?

[DileepKumar]

Hi,
I have one problem..
I want to find the current location accuracy..

Android have Location.getAccuracy() . So easy to get the accuracy.
But, I don't know how to do in j2me?
So, anyone know the answer means Help me...

If JSR-179 APIs do not return some accuracy value to J2ME, then there is no way to get it with J2ME. Check the JSR-179 API documentation to see what they return and do not return.

Full JSR-179 specification on http://jcp.org/aboutJava/communityprocess/final/jsr179/ and through there on http://www.developer.nokia.com/Devel...s.xhtml#jsr179

You have any-other Idea to manual calculation.....

Please send me...

I can't imagine any possible way to calculate something yourself, if you don't have access to the data to base the calculations on in the first place. Switch to using Symbian phones and use Symbian C++, and you might get it, if there's a Symbian-level API for the accuracy data.

I get the Horizontal Accuracy and Vertical Accuracy in j2me Using Location API.
But, I want find current location accuracy.
So,Any formula or any built in function in j2me?

you can retrieve the NMEA string with the JSR-179 API, in there you will find stuff like the HDOP, VDOP etc values... those are used to calculate the precision of the fix, another "simple" way is to read out the number of "visible" satellites, the more (in general, thats not always true though0 the better the fix...
You can google those terms (VDOP HDOP etc) which will yield you the knowledge on how to use them (it is somewhat complex stuff)... http://en.wikipedia.org/wiki/Dilutio...sion_%28GPS%29
