As a developer of SpeedView: GPS speedometer for Android, I must have tried every possible solution to this problem, all with the same negative result. Let’s reiterate what doesn’t work: onStatusChanged() isn’t getting called on Eclair and Froyo. Simply counting all available satellites is, of course, useless.

Here’s a Python version: from math import radians, cos, sin, asin, sqrt def haversine(lon1, lat1, lon2, lat2): “”” Calculate the great circle distance in kilometers between two points on the earth (specified in decimal degrees) “”” # convert decimal degrees to radians lon1, lat1, lon2, lat2 = map(radians, [lon1, lat1, lon2, lat2]) # haversine formula … Read more
How to emulate GPS location in the Android Emulator?
the GPS can be toggled by exploiting a bug in the power manager widget. see this xda thread for discussion. here’s some example code i use private void turnGPSOn(){ String provider = Settings.Secure.getString(getContentResolver(), Settings.Secure.LOCATION_PROVIDERS_ALLOWED); if(!provider.contains(“gps”)){ //if gps is disabled final Intent poke = new Intent(); poke.setClassName(“com.android.settings”, “com.android.settings.widget.SettingsAppWidgetProvider”); poke.addCategory(Intent.CATEGORY_ALTERNATIVE); poke.setData(Uri.parse(“3”)); sendBroadcast(poke); } } private void turnGPSOff(){ … Read more
I have created a small application with step by step description to get current location’s GPS coordinates. Complete example source code is in Get Current Location coordinates , City name – in Android. See how it works: All we need to do is add this permission in the manifest file: <uses-permission android:name=”android.permission.ACCESS_FINE_LOCATION” /> And create … Read more
