清除Java Complier错误

我在跟踪集成地图上的活动时遇到了Java编译器错误。同一错误在三个位置发生。

这是错误消息: 错误:找不到符号变量OnMapReadyCallback

这是第一个的代码

private void initilizeMap() {
    if (googleMap == null) {
        googleMap = ((MapFragment) getFragmentManager().findFragmentById(
                R.id.map)).getMapAsync(OnMapReadyCallback);

        googleMap.setMyLocationEnabled(true);


        // check if map is created successfully or not
        if (googleMap == null) {
            Toast.makeText(getApplicationContext(),
                    "Sorry! unable to create maps", Toast.LENGTH_SHORT)
                    .show();
        }
    }

这是第二个:

}
private void initilizeMap() {
    if (googleMap == null) {
        googleMap = ((MapFragment) getFragmentManager().findFragmentById(
                R.id.map)).getMapAsync(OnMapReadyCallback);

        googleMap.setMyLocationEnabled(true);

        LatLng latLng = new LatLng(gps.getLatitude(), gps.getLongitude());

        //googleMap.setOnMarkerClickListener(this);
        // check if map is created successfully or not
        if (googleMap == null) {
            Toast.makeText(getApplicationContext(),
                    "Sorry! unable to create maps", Toast.LENGTH_SHORT)
                    .show();
        }
    }

这是第三个:

private void initilizeMap() {
    if (googleMap == null) {
        googleMap = ((MapFragment) getFragmentManager().findFragmentById(
                R.id.map)).getMapAsync(OnMapReadyCallback);

        googleMap.setMyLocationEnabled(true);

        LatLng latLng = new LatLng(gps.getLatitude(), gps.getLongitude());
        CameraUpdate cameraUpdate = CameraUpdateFactory.newLatLngZoom(latLng, 14);
        googleMap.animateCamera(cameraUpdate);

        //googleMap.setOnMarkerClickListener(this);
        // check if map is created successfully or not
        if (googleMap == null) {
            Toast.makeText(getApplicationContext(),
                    "Sorry! unable to create maps", Toast.LENGTH_SHORT)
                    .show();
        }
    }
}

我正在运行以下内容: Android SDK Build-Toos 29-rc2

以及 Android Q预览 Android 9.0(Pie),并已安装了Andriod 8.1至4.0.3(IceCreamSandwich)的所有内容

任何帮助将不胜感激! E
