"Exception for the locationjava.lang.IndexOutOfBoundsException: Invalid index 0, size is 0"
I had this error for no reason in my android app which was able to fetch the current longitude latitude of current location using LocationTracker and later on by the help of Geocoder was able to display the name of the place in string.
I didnt see anything wrong with my code also before my app was working fine.
Later, I found out the problem was due to not granting permission for the app I had to go to
>>setting>>application>>app manager>>appname>>>>permissions and turn on the location toggle button.
After rerunning the app the problem was solved.
My runtime message showed error in this line before solving the problem
String address = addresses.get(0).getAddressLine(0);
which is written under button listener for the button which on clicking we get the location of the place
Are there any other reasons possible for similar error??
Also I think good practice will be to place the code in MainActivity so one can grant the permission through the application itself and dont have to go to the setting>>application....and so on. Any suggestion in this matter??
also let me know whether the technique i used to solve the problem was right or not??

I'm working on my Android app which is required to track location of android periodically. The result will be sent to my server(maybe in php) whenever I click button "Get Location" on the server or sent periodically if I click button "Track Location", I have searched much for this topic but it seem to me that they are not helpful for me.
Can anyone give me a detail solution with full code?
Any help will be appreciated !
If you want to get track location right after click Get Location on the server, you have to implement an API to check if need to upload location, then create a service on client with calling this API, then upload when needed. And for Track location by period, you could also use service for it. For details, please try to search by yourself, there are many solutions for them already.
P/S: noone will give you a detail solution with full code, it's your job, not us!
I am working on app. When user click on button he will get current location using GPS.
All is working fine but one problem.
Problem
There might be some location where gps will not work...like closed area...and gps can not find location...at that time it will return previously know location...Previously known location may be too older or wrong.
so at that time I want no location found instead of last location.
Is there any way to check if fix is available or not ?

for Google map v2(the latest version),you should implements the LocationSource to update current location , than also you do need make a location request use LocationClient to get current location then update it with LocationSource.OnLocationChangedListener
I want to get user's location in my app. So, I read documentations and know how to get it work. But, if user haven't set "Alloy apps to use internet/GPS to get location" in preferences, my app crashes.
The only way I found is to show dialog that location settings are not enabled and to go programmaticaly to location preferences.
But is there another way to solve this? I saw many apps (like yandex.maps) that do not request this settings being enabled.
well, your app should not install if the user doesn't agree to the terms of use, and allow the permissions requested.
still you should check to see that there's a way to look the information up when you want it.
in your code, before the actual test for user's location, you should probably call a function that checks for all the location manager listings, and return false if there's no way to determine this.
if the function returns false, you should prompt the user and do nothing. else, you should do what it is you're trying to do.
try reading vogella's tutorial about using location manager
