When I try to share an screenshot via the Samsung email app the preview of the image I am sending is wrong. It happens only with the Samsung email app.
Here is my code:
-------here I am taking a screenshot-----------
String mPath = "";
try {
// image naming and path to include sd card appending name you choose for file
mPath = Environment.getExternalStorageDirectory().toString() + "/" + "share" + ".jpeg";
// create bitmap screen capture
View v1 = getActivity().getWindow().getDecorView().getRootView();
v1.setDrawingCacheEnabled(true);
Bitmap bitmap = Bitmap.createBitmap(v1.getDrawingCache());
v1.setDrawingCacheEnabled(false);
File imageFile = new File(mPath);
FileOutputStream outputStream = new FileOutputStream(imageFile);
int quality = 100;
bitmap.compress(Bitmap.CompressFormat.JPEG, quality, outputStream);
outputStream.flush();
outputStream.close();
-------sending a screen shot via intent-----------
Uri imageUri = Uri.parse(sorcUrl);
Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("image/jpeg");
intent.putExtra(Intent.EXTRA_STREAM, imageUri);
startActivity(Intent.createChooser(intent, "Share"));
} catch (Throwable e) {
// Several error may come out with file handling or OOM
e.printStackTrace();
}

How to get Android OS Phone display a screenshot every minute and send it by email?
use following code to get screen shot from your mobile
private void takeScreenshot() {
Date now = new Date();
android.text.format.DateFormat.format("yyyy-MM-dd_hh:mm:ss", now);
try {
// image naming and path to include sd card appending name you choose for file
String mPath = Environment.getExternalStorageDirectory().toString() + "/" + now + ".jpg";
// create bitmap screen capture
View v1 = getWindow().getDecorView().getRootView();
v1.setDrawingCacheEnabled(true);
Bitmap bitmap = Bitmap.createBitmap(v1.getDrawingCache());
v1.setDrawingCacheEnabled(false);
File imageFile = new File(mPath);
FileOutputStream outputStream = new FileOutputStream(imageFile);
int quality = 100;
bitmap.compress(Bitmap.CompressFormat.JPEG, quality, outputStream);
outputStream.flush();
outputStream.close();
openScreenshot(imageFile);
} catch (Throwable e) {
// Several error may come out with file handling or OOM
e.printStackTrace();
}
}
add permission in your manifest
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
And this is how you can open the recently generated image:
private void openScreenshot(File imageFile) {
Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
Uri uri = Uri.fromFile(imageFile);
intent.setDataAndType(uri, "image/*");
startActivity(intent);
}
I need to share an image (.png format) with transparent background, through sent_action intent.
I searched a lot and tried a lot of samples but couldn't find the solution.
The is this method in witch the image will get shared directly from the resources, but for some reason from some point it has stop working.
Uri url = Uri.parse("android.resource://"
+ getPackageName() + "/" + R.drawable.ic_launcher);
Intent share_intent = new Intent();
share_intent.setAction(Intent.ACTION_SEND);
share_intent.setType("image/png");
share_intent.putExtra(Intent.EXTRA_STREAM,
Uri.fromFile(new File(url.toString())));
startActivity(Intent.createChooser(share_intent, "choose app"));
and there is this function which works fine, the problem is it adds a black background to the image.
private void share3()
{
Bitmap bitmap;
OutputStream output;
bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.ic_launcher);
File filepath = Environment.getExternalStorageDirectory();
File dir = new File(filepath.getAbsolutePath() + "/Gallery/");
dir.mkdirs();
File file = new File(dir, "ic_launcher" + ".png");
try {
Intent share = new Intent(Intent.ACTION_SEND);
share.setType("image/png");
output = new FileOutputStream(file);
bitmap. compress(Bitmap.CompressFormat.PNG/*Bitmap.CompressFormat.PNG*/, 0, output);
output.flush();
output.close();
Uri uri = Uri.fromFile(file);
share.putExtra(Intent.EXTRA_STREAM, uri);
startActivity(Intent.createChooser(share, "choose app"));
} catch (Exception e) {
e.printStackTrace();
}
}
I need to share the image from "raw" folder in the resources and share it without background. What should I do?
I found the problem, It is telegram itself. Telegram adds a black background to .png images you share.
Try this ..its work for me to share image from drawable folder.
Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.ic_launcher);
String path = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES) + "/LatestShare.png";
OutputStream out = null;
File file = new File(path);
try {
out = new FileOutputStream(file);
bitmap.compress(Bitmap.CompressFormat.PNG, 100, out);
out.flush();
out.close();
} catch (Exception e) {
e.printStackTrace();
}
path = file.getPath();
Uri bmpUri = Uri.parse("file://" + path);
Intent shareIntent = new Intent();
shareIntent = new Intent(Intent.ACTION_SEND);
shareIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
shareIntent.putExtra(Intent.EXTRA_STREAM, bmpUri);
shareIntent.setType("image/png");
startActivity(Intent.createChooser(shareIntent, "Share with"));
I use below code to take screen shot from my layout and share it via android intent but the captured screen shot in the selected app is not showing any thing.
#Override
public void onClick(View view) {
shareBitmap(this,takeScreenshot());
}
public Bitmap takeScreenshot() {
try{
View rootView = getWindow().getDecorView().findViewById(R.id.lyt_main_report_activity);
rootView.setDrawingCacheEnabled(true);
return rootView.getDrawingCache();
}catch (Exception ex){
ex.printStackTrace();
}
return null;
}
public static void shareBitmap(Context context, Bitmap bitmap){
//save to sd card
try {
File cachePath = new File(context.getCacheDir(), "images");
cachePath.mkdirs(); // don't forget to make the directory
FileOutputStream stream = new FileOutputStream(cachePath + "/image.png"); // overwrites this image every time
bitmap.compress(Bitmap.CompressFormat.PNG, 100, stream);
stream.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
try{
//start share activity
File imagePath = new File(context.getCacheDir(), "images");
File newFile = new File(imagePath, "image.png");
Uri contentUri = Uri.fromFile(newFile); //FileProvider.getUriForFile(context, "com.persianswitch.apmb.app.fileprovider", newFile);
if (contentUri != null) {
Intent shareIntent = new Intent();
shareIntent.setAction(Intent.ACTION_SEND);
//shareIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION); // temp permission for receiving app to read this file
// shareIntent.setDataAndType(contentUri, context. getContentResolver().getType(contentUri));
shareIntent.putExtra(Intent.EXTRA_STREAM, contentUri);
shareIntent.setType("image/*");
context.startActivity(Intent.createChooser(shareIntent, context.getResources().getString(R.string.share_using)));
}
}catch (Exception ex){
ex.printStackTrace();
}
}
Please use this code this is tested code :
public static void takeScreenshot(Context context, View view) {
String path = Environment.getExternalStorageDirectory().toString() +
"/" + "test.png";
View v = view.findViewById(android.R.id.content).getRootView();
v.setDrawingCacheEnabled(true);
v.setDrawingCacheEnabled(true);
Bitmap bitmap = Bitmap.createBitmap(v.getDrawingCache());
v.setDrawingCacheEnabled(false);
OutputStream out = null;
File imageFile = new File(path);
try {
out = new FileOutputStream(imageFile);
// choose JPEG format
bitmap.compress(Bitmap.CompressFormat.JPEG, 90, out);
out.flush();
} catch (FileNotFoundException e) {
// manage exception
} catch (IOException e) {
// manage exception
} finally {
try {
if (out != null) {
out.close();
}
} catch (Exception exc) {}
}
// onPauseVideo();
Intent share = new Intent(Intent.ACTION_SEND);
share.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(imageFile));
share.setType("image/png");
((Activity) context).startActivityForResult(
Intent.createChooser(share, "Share Drawing"), 111);
}
Since DrawingCache() deprecated above 28 so using Canvas will sort the issues for many. below answer can be used for share Screenshot including text without requesting for permissions.
To take the Screenshot
private Bitmap takeScreenShot(View view) {
Bitmap bitmap = Bitmap.createBitmap(view.getWidth(), view.getHeight(), Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(bitmap);
view.draw(canvas);
return bitmap;
}
To share the Screenshot
private void shareContent(Bitmap bitmap) {
String bitmapPath = MediaStore.Images.Media.insertImage(
binding.getRoot().getContext().getContentResolver(), bitmap, "title", "");
Uri uri = Uri.parse(bitmapPath);
Intent shareIntent = new Intent(Intent.ACTION_SEND);
shareIntent.setType("image/*");
shareIntent.putExtra(Intent.EXTRA_SUBJECT, "App");
shareIntent.putExtra(Intent.EXTRA_TEXT, "Currently a new version of KiKi app is available.");
shareIntent.putExtra(Intent.EXTRA_STREAM, uri);
binding.getRoot().getContext().startActivity(Intent.createChooser(shareIntent, "Share"));
}
if nothing happens it means your Bitmap is null kindly check that. or you could also fall on View.buildDrawingCache(); which will draw the View to Bitmap and then call your View.getDrawingCache();
also When hardware acceleration is turned on, enabling the drawing cache has no effect on rendering because the system uses a different mechanism for acceleration which ignores the flag. If you want to use a Bitmap for the view, even when hardware acceleration is enabled, see setLayerType(int, android.graphics.Paint) for information on how to enable software and hardware layers.

hope it helps
Tipp:The checked answer works when your device has external storage. On the Samsung 6 for example, it doesnt. Therefore you need to work with fileprovider.
Just incase somebody fell into this trap like me. The problem is that you are putting the name of the image twice.
FileOutputStream stream = new FileOutputStream(cachePath + "/image.png");
and than again.
File newFile = new File(imagePath, "image.png");
Change The seconed one to
File newFile = new File(imagePath);
Otherwise the contentUri give you the bitmap of your screenshot. I hope this helps someone. Took me 3 hours to figure it out :)
New to android. I'm taking a screen shot of my activity, and emailing it out. Here's my process:
public void emailScreenShot() {
//get bitmap of activity
View v = DeSlip.this.getWindow().getDecorView();
Bitmap bitmap = Bitmap.createBitmap(v.getWidth(),
v.getHeight(), Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(bitmap);
v.draw(canvas);
//save bitmap externally
String path = Environment.getExternalStorageDirectory().toString();
File file = new File(path, AName + "vs" + BName+ ".JPEG");
Uri pngUri = Uri.fromFile(file);
FileOutputStream fos;
//compress
try {
fos = new FileOutputStream(file);
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, fos);
fos.flush();
fos.close();
} catch (FileNotFoundException e) {
Log.e("BoutSlip", e.getMessage(), e);
} catch (IOException e) {
Log.e("BoutSlip", e.getMessage(), e);
}
//email intent
Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
emailIntent.setType("image/png");
emailIntent.putExtra(android.content.Intent.EXTRA_STREAM, pngUri);
startActivity(Intent.createChooser(emailIntent, "Send image using:"));
}
This works well, and gets my stuff out into the internet. My question is regarding using the external storage (I have permission in manifest). Is there some process I should be doing in order to remove or delete this bitmap after I have finished using it before I close? Or will the android memory management automatically take care of that with other stack items?
My gut says no, however you do want the bitmap around long enough to email (but I wasn't seeing it on the gallery app, so I know it's not available there).
I am writing an app to share image.
I wrote the code but getting problems.
What I am doing
1: Saving the image temporarily in Internal Stoarge
2: Passing the URI to share the image.
Image is successfully saved in internal storage but not getting share on whatsapp.
When I share it on whatsapp, Whatsapp get opens, I select recipient, whatsapp processes it and says "Retry".
Code:
public void shareImage(View V)
{
Bitmap icon = BitmapFactory.decodeResource(getResources(), R.drawable.download);
Intent share = new Intent(Intent.ACTION_SEND);
share.setType("image/jpeg");
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
icon.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
File file = new File(Environment.getExternalStorageDirectory()
+ File.separator + "myDownloadedImage.jpg");
try
{
file.createNewFile();
FileOutputStream fo = new FileOutputStream(file);
fo.write(bytes.toByteArray());
fo.close();
} catch (IOException e) {
Toast.makeText(this, "Some error in Writing"+e.getMessage(), Toast.LENGTH_LONG).show();
e.printStackTrace();
}
Uri downloadLocation=Uri.fromFile(file);
share.putExtra(Intent.EXTRA_STREAM, downloadLocation);
startActivity(Intent.createChooser(share, "Share Image"));
}
Image succesfully get saved on internal storage but not getting shared on whatsapp.
The screenshot is below. We can see images are not shared successfully.
Use below code to fetch image and make uri:
File file = new File(Environment.getExternalStoragePublicDirectory(
Environment.DIRECTORY_DOWNLOADS), "share_image_" + System.currentTimeMillis() + ".png");
file.getParentFile().mkdirs();
FileOutputStream out = new FileOutputStream(file);
bitmap.compress(Bitmap.CompressFormat.PNG, 90, out);
out.close();
bmpUri = Uri.fromFile(file);
Now pass the bmpUri in:
shareIntent.putExtra(Intent.EXTRA_STREAM, bmpUri);
This should make your image share.
