Android Question Mock Location

[Lucas Eduardo]

Hello,
I was trying to do this service mock location from this post https://www.b4x.com/android/forum/threads/mock-locationprovider-lib.14266/, but the example don't work.

I'm getting this error

** Activity (main) Create, isFirst = true **
** Activity (main) Resume **
*** Service (mlpservice) Create ***
** Service (mlpservice) Start **
Error occurred on line: 110 (MLPservice)
java.lang.IllegalArgumentException: Incomplete location object, missing timestamp or accuracy? Location[gps 52,569035,13,196660 hAcc=2 et=?!? alt=84.0 vel=0.0 bear=75.0 vAcc=??? sAcc=??? bAcc=???]

I searched on internet and found this https://stackoverflow.com/questions...not-being-set-despite-all-parameters/30381074

How can i fix the problem?

My manifest

AddManifestText(
<uses-sdk android:minSdkVersion="5" android:targetSdkVersion="28"/>
<supports-screens android:largeScreens="true"
    android:normalScreens="true"
    android:smallScreens="true"
    android:anyDensity="true"/>)
SetApplicationAttribute(android:icon, "@drawable/icon")
SetApplicationAttribute(android:label, "$LABEL$")
CreateResourceFromFile(Macro, Themes.DarkTheme)
'End of default text.
AddPermission(android.permission.ACCESS_FINE_LOCATION)
AddPermission(android.permission.ACCESS_COARSE_LOCATION)
AddPermission(android.permission.ACCESS_MOCK_LOCATION)

I tried with older sdkVersion, but also did not work.
I also already checked in developer option the app of mock location

Thanks.

How can i fix the problem?

only if you have the source of the lib. i guess. I tried a code i found on SO

Location loc = new Location(mocLocationProvider);
Location mockLocation = new Location(mocLocationProvider); // a string
mockLocation.setLatitude(-26.902038); // double
mockLocation.setLongitude(-48.671337);
mockLocation.setAltitude(loc.getAltitude());
mockLocation.setTime(System.currentTimeMillis());
lm.setTestProviderLocation( mocLocationProvider, mockLocation);

It results in the same error.

After changing it to

    Location loc = new Location(mocLocationProvider);
    Location mockLocation = new Location(mocLocationProvider); // a string
    mockLocation.setLatitude(-26.902038);  // double
    mockLocation.setLongitude(-48.671337);
    mockLocation.setAltitude(loc.getAltitude());
    mockLocation.setTime(System.currentTimeMillis());
    mockLocation.setAccuracy(1);
    mockLocation.setElapsedRealtimeNanos(SystemClock.elapsedRealtimeNanos());
    lm.setTestProviderLocation( mocLocationProvider, mockLocation);

it no longer crashes.
Though this is only a quit and dirty test. It is not really a library and it is not using any services.... Nothing i can share at this time.
