[android-beginners] Re: Calculating distance between GPS position and way_point
Thank you for your input.
I have tried using it but it seems to be more challenging than
expected.
I am importíng android.location.location and then trying the line
float results [] = distanceBetween(lat_a1, lng_a1, lat_b1, lng_b1);
where lat_a1, lng_a1, lat_b1 and lng_b1 have all been converted to
double (I am using them as float earlier in my program).
The values of lat_a1 and lat_b1 equals the GPS coordinates read using
location.getLatitude(); and location.getLongitude();
My problem is that I get the error message:
The method distanceBetween(double, double, double, double) is
undefined for the type new LocationListener(){}
and I don't know how to interprete it.
Furthermore, I will be very thankful is you can help me by reading the
time, and timedifference between a number of readings, as I need the
timedifference to estimate an average speed over a distance travelled.
Thank you for your help

I understand all the input parameters, but what about the output
float results[]
Does it mean that I can write the line
distanceBetween(double startLatitude, double startLongitude, double
endLatitude, double endLongitude, float[] results);
Does it mean that if I enter the command

Well that doesn't make sense since it doesn't match the function
signature...
My problem is that I get the error message: The method
distanceBetween(double, double, double, double) is undefined for the type
new LocationListener(){} and I don't know how to interprete it.
This means exactly what it says - that the method you're using,
distanceBetween, is not defined for the type for which you're trying to use
it.
You use it like this:
float[] results = new float[1]; // 1, 2 or 3 depending on what information
you want
Location.distanceBetween(lat1, lon1, lat2, lon2, results);
float distance = results[0];
Furthermore, I will be very thankful is you can help me by reading
the time, and timedifference between a number of readings, as I need
the timedifference to estimate an average speed over a distance travelled.
I have no idea what you're asking.
I understand all the input parameters, but what about the output float
results[] Does it mean that I can write the line
distanceBetween(double startLatitude, double startLongitude, double
endLatitude, double endLongitude, float[] results);
See above.

[android-beginners] Re: Problems with Google Map View tutorial
Thanks Dave, I will look into the LogCat window and see what it says there. I will look in the list of apps as well to see if the Google Map View is listed. The other tutorials just launch when running through the Eclipse IDE, and this one didn't.

Re: [android-beginners] Finger swipe in Android API level 3 (OS 1.5) ?
It is admittedly difficult to get it to work in 1.5... I have implemented it for my app on the market (AppSwipe!) but it was not easy. It might be a day or two before I have a chance to sit down and look at my code but as soon as I can, I will post something here to at least point you in the right direction. Thanks, Justin -- There are only 10 types of people in the world...

When searching for information about how to code up recognition of a finger swipe across the screen, I find most references to the Gesture API added in API level 4 (OS 1.6). However, there are still quite a few devices (The HTC Droid Eris, for example. And the ole G1.) that are running 1.5. The rest of my app is working just fine requiring only API level 3, but I would like to add swipe recognition. The home screens on the afore-mentioned OS 1.5 devices detect swipes to go across pages, so it must be possible in there somewhere. It is just that it's really hard before the API level 4 Gesture code came in, or is it really effectively not possible? Can anyone tell me how to detect swipes (just a directional swipe left or right across the screen) in OS 1.5 (API level 3, or below) ?
