android - ポリラインが間違った位置から線を引く

Question

ユーザーの動きにポリラインを描画するアプリを開発しています。今のところ、GoogleMap を取得しました。このアプリを起動すると、未知の場所から自分の場所までを描くポリラインが表示されます。ユーザーが動き始めたときに、このポリラインの描画を開始したいだけです。誰でも私のコードの何が問題なのか教えてもらえますか?

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Log.d("MYTAG","onCreate()");
    mGoogleApiClient = new GoogleApiClient.Builder(getActivity())
            .addConnectionCallbacks(this)
            .addOnConnectionFailedListener(this)
            .addApi(LocationServices.API)
            .build();
    if (mGoogleApiClient != null)
        Log.d("MYTAG","Google api created!");
    mLocationRequest = LocationRequest.create()
            .setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY)
            .setInterval(10 * 1000)        // 10 seconds, in milliseconds
            .setFastestInterval(1 * 1000) // 1 second, in milliseconds
            .setSmallestDisplacement(10);
