Function Ｇｅｏｌｏｃａｔｉｏｎ”get CurrentPosition"

Nice to meet you.

I am Japanese.
Since English is not good, because you are creating a message using Google’s translation feature, I’m sorry if there is a hard sentence to read.

I, the functional part of the Near me, we want to change the ability to set up a marker to get the current location.
Is it possible.
Also, I think from the acquired current location and want to be able to navigate to the desired location.

In some cases, rather than enter the part of the “Enter Your Location” details page directly, set up a button for the current location acquisition, we want to be able to automatically obtain in the button action.

However, I tried to experiment does not work.

The solution is in trouble not found.
Please tell me if there is a way.

Thank you.
