onMapReady seems not to work the way it should in my route tracking activity. In the current version of a route tracking activity that I implemented in java under Android Studio NeueRouteAufzeichnen.java (Neue Route Aufzeichnen -German- means Start recording a new route) I added the following in my onMapReady
if(mLastLocation != null) {
LatLng myPosition = new LatLng(mLastLocation.getLatitude(), mLastLocation.getLongitude());
map.addMarker(new MarkerOptions().position(myPosition).title("myPosition"));
map.moveCamera(CameraUpdateFactory.newLatLng(myPosition));
} else{
LatLng sydney = new LatLng(-34, 151);
map.addMarker(new MarkerOptions().position(sydney).title("Marker in Sydney"));
map.moveCamera(CameraUpdateFactory.newLatLng(sydney));
}
to ckeck whether mLastLocation is null. When I move to this activity in my App I see as if Google Maps is about to open a map view then land in an other activity to which I don't refer to in my code. I see neither my current place nor Sydney.
Here is my NeueRouteAufzeichnen.java

Any hints or help with regard to why my onMapReady doesn't work the way it should?
EDIT : I see the following fatal exception in my logcat when starting this activity from my App:

EDIT 2
When I use
ACCURACY_FINE
in criteria.setAccuracy(Criteria.ACCURACY_FINE); or uncomment setAccuracy I get a force close when running as well. My logs say that it happens in line 155
155 else{
156 LatLng sydney = new LatLng(-34, 151);
157 map.addMarker(new MarkerOptions().position(sydney).title("Marker in Sydney"));
158 map.moveCamera(CameraUpdateFactory.newLatLng(sydney));
Here is the log message I got after setting accuracy to fine:
06-17 19:33:27.170 20083-20083/com.noureddine_ouertani.www.wocelli50 E/AndroidRuntime: FATAL EXCEPTION: main Process: com.noureddine_ouertani.www.wocelli50, PID: 20083 java.lang.IllegalArgumentException: accuracy=3 at android.location.Criteria.setAccuracy(Criteria.java:223) at com.noureddine_ouertani.www.wocelli50.NeueRouteAufzeichnen.onMapReady(NeueRouteAufzeichnen.java:155) at com.google.android.gms.maps.SupportMapFragment$zza$1.zza(Unknown Source) at com.google.android.gms.maps.internal.zzo$zza.onTransact(Unknown Source) at android.os.Binder.transact(Binder.java:380) at wv.a(:com.google.android.gms.DynamiteModulesB:82) at maps.ag.t$5.run(Unknown Source) at android.os.Handler.handleCallback(Handler.java:739) at android.os.Handler.dispatchMessage(Handler.java:95) at android.os.Looper.loop(Looper.java:135) at android.app.ActivityThread.main(ActivityThread.java:5538) at java.lang.reflect.Method.invoke(Native Method) at java.lang.reflect.Method.invoke(Method.java:372) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:960) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:755)
the same happens when I use
ACCURACY_COARSE
