Final Update
The feature request has been fulfilled by Google. Please see this answer below.
Original Question
Using the old version of the Google Maps Android API, I was able to capture a screenshot of the google map to share via social media. I used the following code to capture the screenshot and save the image to a file and it worked great:
public String captureScreen()
{
String storageState = Environment.getExternalStorageState();
Log.d("StorageState", "Storage state is: " + storageState);
// image naming and path to include sd card appending name you choose for file
String mPath = this.getFilesDir().getAbsolutePath();
// create bitmap screen capture
Bitmap bitmap;
View v1 = this.mapView.getRootView();
v1.setDrawingCacheEnabled(true);
bitmap = Bitmap.createBitmap(v1.getDrawingCache());
v1.setDrawingCacheEnabled(false);
OutputStream fout = null;
String filePath = System.currentTimeMillis() + ".jpeg";
try
{
fout = openFileOutput(filePath,
MODE_WORLD_READABLE);
// Write the string to the file
bitmap.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 = "";
}
return filePath;
}
However, the new GoogleMap object used by V2 of the api does not have a "getRootView()" method like MapView does.
I tried to do this:
SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
.findFragmentById(R.id.basicMap);
View v1 = mapFragment.getView();
But the screenshot that I get does not have any map content and looks like this:
Has anyone figured out how to take a screenshot of the new Google Maps Android API V2?
Update
I also tried to get the rootView this way:
View v1 = getWindow().getDecorView().getRootView();
This results in a screenshot that includes the action bar at the top of the screen, but the map is still blank like the screenshot I attached.
Update
A feature request has been submitted to Google. Please go star the feature request if this is something you want google to add in the future:Add screenshot ability to Google Maps API V2
Update - Google has added a snapshot method**!:
The feature request for a method to take a screen shot of the Android Google Map API V2 OpenGL layer has been fulfilled.
To take a screenshot, simply implement the following interface:
public abstract void onSnapshotReady (Bitmap snapshot)
and call:
public final void snapshot (GoogleMap.SnapshotReadyCallback callback)
Example that takes a screenshot, then presents the standard "Image Sharing" options:
public void captureScreen()
{
SnapshotReadyCallback callback = new SnapshotReadyCallback()
{
@Override
public void onSnapshotReady(Bitmap snapshot)
{
// TODO Auto-generated method stub
bitmap = snapshot;
OutputStream fout = null;
String filePath = System.currentTimeMillis() + ".jpeg";
try
{
fout = openFileOutput(filePath,
MODE_WORLD_READABLE);
// Write the string to the file
bitmap.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);
}
};
mMap.snapshot(callback);
}
Once the image is finished being captured, it will trigger the standard "Share Image" dialog so the user can pick how they'd like to share it:
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);
}
}
Documentation is here
Below are the steps to capture screen shot of Google Map V2 with example
Step 1. open Android Sdk Manager (Window > Android Sdk Manager)
then Expand Extras
now update/install Google Play Services to Revision 10
ignore this step if already installed
Read Notes here https://developers.google.com/maps/documentation/android/releases#august_2013
Step 2. Restart Eclipse
Step 3. import com.google.android.gms.maps.GoogleMap.SnapshotReadyCallback;
Step 4. Make Method to Capture/Store Screen/image of Map like below
public void CaptureMapScreen()
{
SnapshotReadyCallback callback = new SnapshotReadyCallback() {
Bitmap bitmap;
@Override
public void onSnapshotReady(Bitmap snapshot) {
// TODO Auto-generated method stub
bitmap = snapshot;
try {
FileOutputStream out = new FileOutputStream("/mnt/sdcard/"
+ "MyMapScreen" + System.currentTimeMillis()
+ ".png");
// above "/mnt ..... png" => is a storage path (where image will be stored) + name of image you can customize as per your Requirement
bitmap.compress(Bitmap.CompressFormat.PNG, 90, out);
} catch (Exception e) {
e.printStackTrace();
}
}
};
myMap.snapshot(callback);
// myMap is object of GoogleMap +> GoogleMap myMap;
// which is initialized in onCreate() =>
// myMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map_pass_home_call)).getMap();
}
Step 5. Now call this CaptureMapScreen()
method where you want to capture the image
in my case i am calling this method on Button click in my onCreate()
which is working fine
like:
Button btnCap = (Button) findViewById(R.id.btnTakeScreenshot);
btnCap.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
try {
CaptureMapScreen();
} catch (Exception e) {
// TODO: handle exception
e.printStackTrace();
}
}
});
Edit : this answer is no longer valid - the feature request for screenshots on Google Maps Android API V2 has been fulfilled. See this answer for an example .
Original Accepted Answer
Since the new Android API v2 Maps are displayed using OpenGL, there are no possibilities to create a screenshot.
I capctured Map screenshot.It will be helpful
private GoogleMap map;
private static LatLng latLong;
`
public void onMapReady(GoogleMap googleMap) {
map = googleMap;
setMap(this.map);
animateCamera();
map.moveCamera (CameraUpdateFactory.newLatLng (latLong));
map.setOnMapLoadedCallback (new GoogleMap.OnMapLoadedCallback () {
@Override
public void onMapLoaded() {
snapShot();
}
});
}
`
snapShot() method for taking screenshot of map
public void snapShot(){
GoogleMap.SnapshotReadyCallback callback=new GoogleMap.SnapshotReadyCallback () {
Bitmap bitmap;
@Override
public void onSnapshotReady(Bitmap snapshot) {
bitmap=snapshot;
try{
file=new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES),"map.png");
FileOutputStream fout=new FileOutputStream (file);
bitmap.compress (Bitmap.CompressFormat.PNG,90,fout);
Toast.makeText (PastValuations.this, "Capture", Toast.LENGTH_SHORT).show ();
}catch (Exception e){
e.printStackTrace ();
Toast.makeText (PastValuations.this, "Not Capture", Toast.LENGTH_SHORT).show ();
}
}
};map.snapshot (callback);
}
Since the top voted answer doesnt work with polylines and other overlays on top of the map fragment (What I was looking for), I want to share this solution.
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();
}

openShareImageDialog(filePath);
} catch (Exception e) {

};
;
map.snapshot(callback);

I hope this would help to capture the screenshot of your map
Method call:
gmap.setOnMapLoadedCallback(mapLoadedCallback);
Method declaration:
final SnapshotReadyCallback snapReadyCallback = new SnapshotReadyCallback() {
Bitmap bitmap;
@Override
public void onSnapshotReady(Bitmap snapshot) {
bitmap = snapshot;
try {
//do something with your snapshot
imageview.setImageBitmap(bitmap);
} catch (Exception e) {
e.printStackTrace();
}
}
};
GoogleMap.OnMapLoadedCallback mapLoadedCallback = new GoogleMap.OnMapLoadedCallback() {
@Override
public void onMapLoaded() {
gmap.snapshot(snapReadyCallback);
}
};
Use mapcalback for get screenshot of map
GoogleMap.SnapshotReadyCallback callback = new GoogleMap.SnapshotReadyCallback() {
Bitmap bitmap=null;
@Override
public void onSnapshotReady(Bitmap snapshot) {
// TODO Auto-generated method stub
bitmap = snapshot;
try {
saveImage(bitmap);
Toast.makeText(getActivity().getApplicationContext(), "Successful.Screenshot Saved.", Toast.LENGTH_LONG).show();
} catch (Exception e) {
e.printStackTrace();
}
}
private void saveImage(Bitmap bitmap) throws IOException {
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
Date date = new Date();
CharSequence format = android.text.format.DateFormat.format("yyyy-MM-dd_hh:mm:ss", date);
String dirpath = Environment.getExternalStorageDirectory() + "";
File file = new File(dirpath);
if (!file.exists()) {
boolean mkdir = file.mkdir();
}
String path1 = dirpath + "/Documents/SCREENSHOT/";
File imageurl1 = new File(path1);
imageurl1.mkdirs();
File f = new File(path1 +"/"+ format + ".png");
f.createNewFile();
FileOutputStream fo = new FileOutputStream(f);
fo.write(bytes.toByteArray());
fo.close();
}
};
mMap.snapshot(callback);
Eclipse DDMS can capture the screen even it's google map V2.
Try to call /system/bin/screencap or /system/bin/screenshot if you have the "root". I learned that from How Eclipse android DDMS implement "screen capture"
