java.lang.RuntimeException: Methods marked with @UiThread must be executed on the main thread about trust_fall HOT 15 OPEN

Same problem here, anyone get this resolve ?

Edited:
I found another alternative to detect just mock Location (another detection are working), with the same way this plugin do, install Geolocator flutter plugin then use this code :

Future<bool> checkMockLocation() async {
    Position position = await Geolocator().getLastKnownPosition();
    return position.mocked;
  }

Same problem :/

I am also getting this error

when calling
bool canMockLocation = await TrustFall.canMockLocation;

@ENGR-ZEESHAN, Could you post output for flutter doctor please

@anish-adm could you check this Similiar issue, ?

i think this code make error

class GetLastLocation extends TimerTask {
        @Override
        public void run() {
            lm.removeUpdates(locationListenerGps);
            lm.removeUpdates(locationListenerNetwork);
            Location net_loc=null, gps_loc=null;
            if(gps_enabled)
                gps_loc=lm.getLastKnownLocation(LocationManager.GPS_PROVIDER);
            if(network_enabled)
                net_loc=lm.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
            //if there are both values use the latest one
            if(gps_loc!=null && net_loc!=null){
                if(gps_loc.getTime()>net_loc.getTime())
                    locationResult.gotLocation(gps_loc);
                else
                    locationResult.gotLocation(net_loc);
                return;
            }

            if(gps_loc!=null){
                locationResult.gotLocation(gps_loc);

Same problem here, anyone get this resolve ?

Edited:
I found another alternative to detect just mock Location (another detection are working), with the same way this plugin do, install Geolocator flutter plugin then use this code :

Future<bool> checkMockLocation() async {
    Position position = await Geolocator().getLastKnownPosition();
    return position.mocked;
  }

I think its now updated

Future<bool> checkMockLocation() async {
    Position position = await Geolocator.getLastKnownPosition();
    return position.isMocked;
  }

try to execute this code after turning off and turning on location. It gives some kind of Exception.

Is there any update on solving this error. I am also facing the same issue. I am on the latest build of TrustFall and flutter.

from trust_fall.

Same problem here, after building App in release mode.

@sunnykinger , @rp014947 , @wisnuwiry guys just use location plugin your own choice and make sure if permission permitted and get mocked properties from that, if you look into this project code you will notice that this is same way. Or you can make a fork and resolved the issue.

But once again users can pass this checker with many ways (rooted phone etc) so add another validations if your app consent is about real user's location.

Fix running on @UiThread :
@OverRide
public void onMethodCall(MethodCall call, @nonnull final Result result) {
if (call.method.equals("getPlatformVersion")) {
result.success("Android " + android.os.Build.VERSION.RELEASE);
} else if (call.method.equals("isJailBroken")) {
result.success(RootedCheck.isJailBroken(applicationContext));
} else if (call.method.equals("canMockLocation")) {
MockLocationCheck.LocationResult locationResult = new MockLocationCheck.LocationResult(){
@OverRide
public void gotLocation(final Location location){
android.os.Handler handler = new android.os.Handler(Looper.getMainLooper());
handler.post(new Runnable() {
@OverRide
public void run() {
//Got the location!
if(location != null){
result.success(location.isFromMockProvider());
}else {
result.success(false);
}
}
});
}
};
MockLocationCheck mockLocationCheck = new MockLocationCheck();
mockLocationCheck.getLocation(applicationContext, locationResult);
}else if (call.method.equals("isRealDevice")) {
result.success(!EmulatorCheck.isEmulator());
}else if (call.method.equals("isOnExternalStorage")) {
result.success(ExternalStorageCheck.isOnExternalStorage(applicationContext));
}
else {
result.notImplemented();
}
}
