我正在尝试加载地图。请参阅下面的代码

@Override
    public void onStart() {
        super.onStart();
        setUpMapIfNeeded();
    }

    private void setUpMapIfNeeded() {
        // Do a null check to confirm that we have not already instantiated the
        // map.
        if (mMap == null) {
            // Try to obtain the map from the SupportMapFragment.
            mMap = ((SupportMapFragment) getChildFragmentManager()
                    .findFragmentById(R.id.map_frag)).getMap();
            // Check if we were successful in obtaining the map.
            if (mMap != null) {
                setUpMap();
            }
        }
    }

    private void setUpMap() {
        mMap.addMarker(new MarkerOptions().position(new LatLng(0, 0)).title(
                "Marker"));
    }

试试这个我的朋友，

  • 请尝试使用其他密钥。

  • 检查是否所有权限都已授予，例如：

    ACCESS_COARSE_LOCATION

    ACCESS_FINE_LOCATION

    互联网

  • 最后，只需检查 setUpMap() 方法。也许它会起作用
