gps - Android requestLocationUpdates not called properly -


i locate user clicking on button. therefore use code:

lm = getsystemservice(locationmanager.class); provider = locationmanager.gps_provider; listener = new locationlistener() { @override public void onlocationchanged(location location) {    log.e("update","updating location"); } @override public void onstatuschanged(string s, int i, bundle bundle) {  } @override public void onproviderenabled(string s) {  } @override public void onproviderdisabled(string s) {  } };  lm.requestlocationupdates(locationmanager.gps_provider, 0, 0, listener);

the requestlocationupdates method called onlocationchanged method called few times. gps activated , permissions granted.

do have idea why onlocationchanged not called? checked getlastknownlocation false after calling requestlocationupdates.

i think onlocationchanged() not suppose called always, called if location changes.

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
