java.lang.IllegalArgumentException:运行我的路线跟踪活动时精度=3。。。这是GPS精度问题吗？

在我的路线跟踪活动中，onMapReady似乎没有发挥应有的作用。在我在Android Studio NeueRouteAufzeichnen.java下用java实现的路线跟踪活动的当前版本中（Neue route Aufzeichnen-德语-意思是开始记录新路线），我在onMapReady中添加了以下内容

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));
    }

检查mLastLocation是否为空。当我在我的应用程序中移动到此活动时，我看到谷歌地图将要打开一个地图视图，然后进入我在代码中未提及的其他活动。我既看不到我现在的住处，也看不到悉尼

这是我的NeueRouteAufzeichnen.java

以下是我在将精度设置为“精细”后得到的日志消息：
