如何使用Picasso和Google Marker Custom Icon来实现此功能？

我知道如何将Picasso用于图像,但我不知道如何在底部和边框上添加"标记图标".

Picasso.with(mContext)
            .load(url)
            .resize(250, 250)
            .centerInside()
            .into(new Target() {
                @Override
                public void onBitmapLoaded(Bitmap bitmap, Picasso.LoadedFrom from) {
                    Marker driver_marker = mMap.addMarker(new MarkerOptions()
                            .position(new LatLng(Double.parseDouble(lat), Double.parseDouble(lng)))
                            .icon(BitmapDescriptorFactory.fromBitmap(bitmap))
                            .title(name)
                            .snippet(address)
                    );


                    @Override
                    public void onBitmapFailed (Drawable errorDrawable){
                    }

                    @Override
                    public void onPrepareLoad (Drawable placeHolderDrawable){
                    }
                });
            }

我在onBitmapLoaded中添加了这个:

Paint paint = new Paint();
    paint.setColor(Color.YELLOW);
    paint.setStrokeWidth(10);
    paint.setShadowLayer(5, 0, 1, Color.RED);

    Canvas canvas = new Canvas(bitmap);
    canvas.drawLine(0, 0, canvas.getWidth(), 0, paint);
    canvas.drawLine(0, 0, 0, canvas.getHeight(), paint);
    canvas.drawLine(0, canvas.getHeight(), canvas.getWidth(), canvas.getHeight(), …

我正在尝试使用Volley发布我的数据但是我无法在服务器上上传我的图像.总是得到像意外的响应代码500的错误http:\\www.mybaseurl.com/upload.php.以下是我试图上传的代码

 public String getStringImage(Bitmap bmp){
    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    bmp.compress(Bitmap.CompressFormat.JPEG, 100, baos);
    byte[] imageBytes = baos.toByteArray();
    String encodedImage = Base64.encodeToString(imageBytes, Base64.DEFAULT);
    return encodedImage;
}

private void uploadImage(){
    //Showing the progress dialog
    final ProgressDialog loading = ProgressDialog.show(this,"Uploading...","Please wait...",false,false);
    StringRequest stringRequest = new StringRequest(Request.Method.POST, UPLOAD_URL,
            new Response.Listener<String>() {
                @Override
                public void onResponse(String s) {
                    //Disimissing the progress dialog
                    loading.dismiss();
                    //Showing toast message of the response
                    Toast.makeText(MainActivity.this, s , Toast.LENGTH_LONG).show();
                }
            },
            new Response.ErrorListener() {
                @Override
                public void …
