Android Google Map V2 screenshot

Question

Currrently I am stuck with one problem which is how to take screenshot of Google map v2. I am developing one application for GPS Tracking, in it one polyline is drawing tracked path. So I want screenshot for map with polyline drawn on the map as well.

I have did many R & D but found that Google map V2 is not provided such kind of facility.

Please help me to solve this issue.

Can you please tell how can be manage the whole tracking route will be in a screenshot, as we can take screenshot of map but somehow it don't let us have full path traveled in a single shot. — Harpreet, Apr 19 '16 at 08:02

Since you are using v2 your map will be managed be either a MapFragment or a SupportMapFragment. Both are subclasses of Fragment which should give you access to getView(). Let's assume you have the following code in your hosting activity:

SupportMapFragment mapFragment = ((SupportMapFragment) getSupportFragmentManager()
                .findFragmentById(R.id.map));
View view = mapFragment.getView();

With that view you can try this approach How to programmatically take a screenshot in Android?.

Is it crashing? You cannot save the picture? The image is not showing the screenshot? Please specify your problem. – André Diermann Jul 23 '13 at 10:50

I based on this post: Capture screen shot of GoogleMap Android API V2

And managed to get a map screenshot with overlays without any problem:

Here is the code:

public void captureScreen()
    {
        GoogleMap.SnapshotReadyCallback callback = new GoogleMap.SnapshotReadyCallback()
        {


            @Override
            public void onSnapshotReady(Bitmap snapshot) {
                try {
                    getWindow().getDecorView().findViewById(android.R.id.content).setDrawingCacheEnabled(true);
                    Bitmap backBitmap = getWindow().getDecorView().findViewById(android.R.id.content).getDrawingCache();
                    Bitmap bmOverlay = Bitmap.createBitmap(
                            backBitmap.getWidth(), backBitmap.getHeight(),
                            backBitmap.getConfig());
                    Canvas canvas = new Canvas(bmOverlay);
                    canvas.drawBitmap(snapshot, new Matrix(), null);
                    canvas.drawBitmap(backBitmap, 0, 0, null);

                    OutputStream fout = null;

                    String filePath = System.currentTimeMillis() + ".jpeg";

                    try
                    {
                        fout = openFileOutput(filePath,
                                MODE_WORLD_READABLE);

                        // Write the string to the file
                        bmOverlay.compress(Bitmap.CompressFormat.JPEG, 90, fout);
                        fout.flush();
                        fout.close();
                    }
                    catch (FileNotFoundException e)
                    {
                        // TODO Auto-generated catch block
                        Log.d("ImageCapture", "FileNotFoundException");
                        Log.d("ImageCapture", e.getMessage());
                        filePath = "";
                    }
                    catch (IOException e)
                    {
                        // TODO Auto-generated catch block
                        Log.d("ImageCapture", "IOException");
                        Log.d("ImageCapture", e.getMessage());
                        filePath = "";
                    }

                    openShareImageDialog(filePath);


                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
        };

       ;


        map.snapshot(callback);
    }

Then I Use this method for social media sharing:

        public void openShareImageDialog(String filePath)
        {
            File file = this.getFileStreamPath(filePath);

            if(!filePath.equals(""))
            {
                final ContentValues values = new ContentValues(2);
                values.put(MediaStore.Images.Media.MIME_TYPE, "image/jpeg");
                values.put(MediaStore.Images.Media.DATA, file.getAbsolutePath());
                final Uri contentUriFile = getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);

                final Intent intent = new Intent(android.content.Intent.ACTION_SEND);
                intent.setType("image/jpeg");
                intent.putExtra(android.content.Intent.EXTRA_STREAM, contentUriFile);
                startActivity(Intent.createChooser(intent, "Share Image"));
            }
            else
            {
                //This is a custom class I use to show dialogs...simply replace this with whatever you want to show an error message, Toast, etc.
               // DialogUtilities.showOkDialogWithText(this, R.string.shareImageFailed);

                Toast.makeText(getBaseContext(),"Se pelo",Toast.LENGTH_SHORT).show();
            }
        }
