Translation

How do I translate for my language?
Especially the polygon screen, the words 'Length' and 'Area' appear above.

App crashes when lunching MapsActivity

I added the MapsActivity in the manifest, defined the style as recommended
false
true

Here is my activity class:

public class MyMap extends AppCompatActivity
{
private static final int REQUEST_CODE = 1;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_another_map);
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (resultCode == RESULT_OK && requestCode == REQUEST_CODE && data != null) {
        DataModel dataModel =
                data.getExtras().getParcelable(MapsActivity.POINTS);
        LatLng[] points = dataModel.getPoints();
    }
}

public void TryMe(View view) {
    DrawingOption.DrawingType currentDrawingType = DrawingOption.DrawingType.POLYGON;
    Intent intent =
            new DrawingOptionBuilder()
                    .withLocation(35.744502, 51.368966)
                    .withMapZoom(14)
                    .withFillColor(Color.argb(60, 0, 0, 255))
                    .withStrokeColor(Color.argb(100, 255, 0, 0))
                    .withStrokeWidth(3)
                    .withRequestGPSEnabling(false)
                    .withDrawingType(currentDrawingType)
                    .build(getApplicationContext());
    startActivityForResult(intent, REQUEST_CODE);
}

}

When I click the button in my layout file to open your MapsActivity I get a crash......Here is what I have in my logcat:
java.lang.RuntimeException: Unable to start activity
Caused by: java.lang.NullPointerException at com.github.bkhezry.mapdrawingtools.ui.MapsActivity.setUpFABs(MapsActivity.java:106)
at com.github.bkhezry.mapdrawingtools.ui.MapsActivity.onCreate(MapsActivity.java:96)

withLocation doesn't work

It still shows the GPS location instead of withLocation(specific location).

RxJava library functions import issue

I have downloaded project. It gives me Rx java import issues all over the project. Do I need to implement rx java library in project?
below are few import issues listed
error: package rx.functions does not exist
import rx.functions.Action1;

import rx.Observable;
import rx.Subscription;
import rx.functions.Action1;
import rx.subscriptions.CompositeSubscription;

etc.

I have implemented "implementation 'io.reactivex.rxjava2:rxjava:2.2.7'" . even though does not works. Please suggest what to do.

Adding support for free drawing

Free drawing can be supported with this library, we just need to handle onDrag event. There are many projects doing that. It would make this a complete solution for drawing over google maps.
