How to attach image to email on Android emailIntent

To send the email the method for the button is;
public void buttonSendEmailClicked(View view) {
File file = saveFileToShare();
Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
emailIntent.setType("application/image");
emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL, new String[]{});
emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT,"Check Out MyPic");
emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, "Taken With Android!");
emailIntent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(file));
startActivityForResult(Intent.createChooser(emailIntent, "Send mail..."), interstitial_request);
}
The saveFileToShare element is this;
public File saveFileToShare() {
try
{
File fileImage = new File(Environment.getExternalStorageDirectory() + "/DCIM/Camera/attachment.png");
if(!fileImage.exists())
{
fileImage.delete();
}
editorImage.setDrawingCacheEnabled(true);
Bitmap bitmap = editorImage.getDrawingCache();
fileImage.createNewFile();
FileOutputStream ostream = new FileOutputStream(fileImage);
bitmap.compress(CompressFormat.PNG, 100, ostream);
ostream.close();
editorImage.invalidate();
editorImage.setDrawingCacheEnabled(false);
return fileImage;
}
catch (Exception e)
{
System.out.print(e);
e.printStackTrace();
return null;
}
}
Saving the image works fine, the save code is;
public void buttonSaveImageClicked(View view) throws IOException {
editorImage.setDrawingCacheEnabled(true);
Bitmap bitmap = editorImage.getDrawingCache();
SaveLayoutToFile saveImage = new SaveLayoutToFile(this, bitmap, editorImage);
String filePath = Environment.getExternalStorageDirectory() + "/DCIM/Camera/wonkydog";
saveImage.execute(filePath);
}
I need to set the email code to grab the image and attach to email.
At the moment when I press the email button it just returns to the title screen without doing anything else.
If I comment out this line
emailIntent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(file));
Then it opens the mail send dialogue, but without attachment of course...

I found the answer, rather than using the emailIntent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(file));
I replaced it with;
emailIntent.putExtra(Intent.EXTRA_STREAM, FileProvider.getUriForFile(EditorActivity.this, "com.myapp.myappname.provider", file));
It now works correctly!

Android Share Intent Image Sharing not working Except WhatsApp

I have checked the uri, the file saved is a bitmap and its returning file. But the image which shows during sharing is not valid. Gmail says it could not attach the attachment, messages app could not load the image.
Text sharing is working fine.
I am new to Android and is having problem sharing image through share intent. I have googled alot, tried various things but still could not find the solution.
public static void shareWallpaper(Context context, int wallpaperResourceId) {
Bitmap bitmap = BitmapFactory.decodeResource(context.getResources(), wallpaperResourceId);
String path = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES) + "/wallpaper" + String.valueOf(wallpaperResourceId) + ".jpg";
OutputStream out = null;
File file = new File(path);
try {
out = new FileOutputStream(file);
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, out);
out.flush();
out.close();
} catch (Exception e) {
e.printStackTrace();
}
Intent shareIntent = new Intent(Intent.ACTION_SEND);
shareIntent.setType("image/*");
shareIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse(file.getPath()));
shareIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
shareIntent.addFlags(Intent.FLAG_GRANT_WRITE_URI_PERMISSION);
context.startActivity(Intent.createChooser(shareIntent, "برنامه مورد نظر خود را انتخاب کنید"));
}

How to share Screenshot of current page by using intent?

I am developing and android blog application where I want to share my current blog page screenshot.I try but it showing file format is not supported..please help me to find my error..Thanks in advance
MyAdapter.java
sendImage.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Bitmap app_snap = ((BitmapDrawable)movie_image.getDrawable()).getBitmap();
String file_path = Environment.getExternalStorageDirectory().getAbsolutePath() + "/SaveImg";
System.out.println("****FILEPATH **** : " + file_path);
File imagePath = new File(Environment.getExternalStorageDirectory() + "/scr.png");
FileOutputStream fos;
try {
fos = new FileOutputStream(imagePath);
System.out.println("****FILEPATH1 **** : " + file_path);
app_snap.compress(Bitmap.CompressFormat.PNG, 200, fos);
System.out.println("****FILEPATH2 **** : " + file_path);
fos.flush();
fos.close();
}
catch (IOException e) {
System.out.println("GREC****** "+ e.getMessage());
}
Intent sharingIntent = new Intent();
Uri imageUri = Uri.parse(imagePath.getAbsolutePath());
sharingIntent.setAction(Intent.ACTION_SEND);
sharingIntent.setType("image/png");
sharingIntent.putExtra(Intent.EXTRA_STREAM, imageUri);
context.startActivity(sharingIntent);
}
});

Here is the code that allowed my screenshot to be stored on an SD card and used later for whatever your needs are:
First, you need to add a proper permission to save the file:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
And this is the code (running in an Activity):
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 DOM
e.printStackTrace();
}
}
And this is how you can open the recently generated image:
private void openScreenshot(File imageFile) {
Intent intent = new Intent();
intent.setAction(Intent.ACTION_SEND);
Uri uri = Uri.fromFile(imageFile);
intent.setDataAndType(uri, "image/*");
startActivity(intent);
}
If you want to use this on fragment view then use:
View v1 = getActivity().getWindow().getDecorView().getRootView();
instead of
View v1 = getWindow().getDecorView().getRootView();
on takeScreenshot() function
Note:
This solution doesn't work if your dialog contains a surface view. For details please check the answer to the following question:
Android Take Screenshot of Surface View Shows Black Screen
if u have any doubt please go through this link

You can get the Bitmap of your screen view inside your layouts. Where view will be your layout views like Linear or RelativeLayout
view.setDrawingCacheEnabled(true);
view.buildDrawingCache();
Bitmap returnedBitmap = view.getDrawingCache();
then have to convert into byte[] so that you can send with the Intent like this following:
ByteArrayOutputStream stream = new ByteArrayOutputStream();
returnedBitmap.compress(Bitmap.CompressFormat.PNG, 100, stream);
byte[] byteArray = stream.toByteArray();
and send data with Intent like this:
Intent intent = new Intent(this, SecondActivity.class);
intent.putExtra("bitmap_",byteArray);
get Intent on your SecondActivity like this:
byte[] byteArray = getIntent().getByteArrayExtra("bitmap_");
Bitmap bmp = BitmapFactory.decodeByteArray(byteArray, 0, byteArray.length);

How can I share images from an Array that uses ImageView feature?

I have a doubt.
How can I share images from an Array that uses ImageView feature?
My array has more than 100 images, an example:
Final int [] photos = {
R.drawable.abrir_a_boca,
R.drawable.rooms,
R.drawable.firmly,
R.drawable.agradeca,
R.drawable.alfaiate,
R.drawable.ancora,
}
To share I'm trying to use Intent.ACTION_SEND
Set.setOnClickListener (new View.OnClickListener () {
#Override
Public void onClick (View v)
{
Intent sharingIntent = new Intent (Intent.ACTION_SEND);
Uri screenshotUri = Uri.parse (photos???);
SharingIntent.setType ("image / *");
SharingIntent.putExtra (Intent.EXTRA_STREAM, screenshotUri);
StartActivity (Intent.createChooser (sharingIntent, "Share image using"));
}
});
How can I share the images?
Thank you so much!!!

You have to do some operations before you share your image, so add the permission in your Manifest.xml:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
Fist, create a Bitmap object from your drawable resource:
Bitmap bitmap= BitmapFactory.decodeResource(getResources(),R.drawable.xxxx);
Then, get the path for you share your image
String path = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES)+"/yourImage.jpg";
OutputStream out = null;
File file=new File(path);
try {
out = new FileOutputStream(file);
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, out);
out.flush();
out.close();
} catch (Exception e) {
e.printStackTrace();
}
path=file.getPath();
Uri uri = Uri.parse("file://"+path);
And finally, create your intent:
Intent intent = new Intent();
intent = new Intent(android.content.Intent.ACTION_SEND);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.putExtra(Intent.EXTRA_STREAM, uri);
intent.setType("image/jpg");
startActivity(Intent.createChooser(intent,"Share with..."));

Android can't get Texview content to share intent

I'm working on a share button to share the current item image and content but i cant seen to get the text from the texView id to work on Intent Share.
I was wondering if anybody knows a better method?
btnShare.setOnClickListener(new OnClickListener() {
public void onClick(View arg0) {
View content = findViewById(R.id.imgPreview);
content.setDrawingCacheEnabled(true);
Bitmap bitmap = content.getDrawingCache();
File root = Environment.getExternalStorageDirectory();
File cachePath = new File(root.getAbsolutePath() + "/DCIM/image.jpg");
try {
cachePath.createNewFile();
FileOutputStream ostream = new FileOutputStream(cachePath);
bitmap.compress(CompressFormat.JPEG, 100, ostream);
ostream.close();
} catch (Exception e) {
e.printStackTrace();
}
TextView tittle = (TextView) findViewById(R.id.txtText);
TextView txtSubText = (TextView) findViewById(R.id.txtSubText);
TextView txtDescription = (TextView) findViewById(R.id.txtDescription);
Intent share = new Intent(Intent.ACTION_SEND);
share.setType("text/plain");
share.putExtra(Intent.EXTRA_SUBJECT, tittle);
share.putExtra(Intent.EXTRA_TEXT, txtSubText);
share.putExtra(Intent.EXTRA_TEXT, txtDescription);
share.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(cachePath));
share.putExtra(Intent.EXTRA_TEXT,"This was share via Almas's Delicias");
startActivity(Intent.createChooser(share,"Share via"));

Change this lines of codes:
share.putExtra(Intent.EXTRA_SUBJECT, tittle.getText().toString());
share.putExtra(Intent.EXTRA_TEXT, txtSubText.getText().toString());
share.putExtra(Intent.EXTRA_TEXT, txtDescription.getText().toString());
