I M Trying To Develop An Android App To Get The Location Using Googleapi. But It Is Showing Error Like Could Not Get The Connection Factory Client

Solution 1:
Use my code to get the location. Turn your gps and wifi on before :-
Use my Code. I have successfully found my current address using coordinates but for that you have to enable wifi and gps. first add all these permissions in your android manifest file
<uses-permissionandroid:name="android.permission.INTERNET" /><uses-permissionandroid:name="android.permission.ACCESS_NETWORK_STATE" /><uses-permissionandroid:name="android.permission.CHANGE_NETWORK_STATE" /><uses-permissionandroid:name="android.permission.ACCESS_WIFI_STATE" /><uses-permissionandroid:name="android.permission.CHANGE_WIFI_STATE" /><uses-permissionandroid:name="android.permission.WAKE_LOCK" /><uses-permissionandroid:name="android.permission.ACCESS_COARSE_LOCATION" /><uses-permissionandroid:name="android.permission.ACCESS_FINE_LOCATION" />AndroidGPSTrackingActivity.java*
