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!

"file:///storage/emulated/0/screenshot.png exposed beyond app through ClipData.Item.getUri()"

I'm trying to set up a share button on my app. The button is supposed to take a screenshot of a particular list view, and then allow the user to share this image via whatever means they want. To do this, I created three methods:
Take the screenshot
Save it in my storage
Share it to the user.
To do this I've written the following code:
public class ViewPlayerHistoryContents extends AppCompatActivity {
public static File imagePath;
public Bitmap takeScreenshot() {
View rootView = findViewById(android.R.id.content).getRootView();
rootView.setDrawingCacheEnabled(true);
return rootView.getDrawingCache();
}
public void saveBitmap(Bitmap bitmap) {
imagePath = new File(Environment.getExternalStorageDirectory() + "/screenshot.png");
FileOutputStream fos;
try {
fos = new FileOutputStream(imagePath);
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, fos);
fos.flush();
fos.close();
} catch (FileNotFoundException e) {
Log.e("GREC", e.getMessage(), e);
} catch (IOException e) {
Log.e("GREC", e.getMessage(), e);
}
}
private void shareIt() {
Uri uri = Uri.fromFile(imagePath);
Intent sharingIntent = new Intent(android.content.Intent.ACTION_SEND);
sharingIntent.setType("image/*");
String shareBody = "In Tweecher, My highest score with screen shot";
sharingIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "My Tweecher score");
sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, shareBody);
sharingIntent.putExtra(Intent.EXTRA_STREAM, uri);
startActivity(Intent.createChooser(sharingIntent, "Share via"));
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.view_player_history);
shareButton = findViewById(R.id.shareButton);
View rootView = getWindow().getDecorView().findViewById(android.R.id.content);
shareButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Bitmap bitmap = takeScreenshot();
saveBitmap(bitmap);
shareIt();
}
});
}
}
With this code I keep getting the following error message:
E/AndroidRuntime: FATAL EXCEPTION: main
Process: com.example.transfergame, PID: 18477
android.os.FileUriExposedException: file:///storage/emulated/0/screenshot.png exposed beyond app through ClipData.Item.getUri()
Which to me sounds like it's because I'm using Uri and not FileProvider?
How should I be incorporating FileProvider in this?
I added the following permissions to my Android manifest file, but it hasn't done anything:
</application>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
How can I fix this error?
Thanks everyone

You can go through this
You have add provider in android manifest and also create the a File Provider in xml/provider.xml as the answer in thus link suggests.

public void captureImage() {
StrictMode.VmPolicy.Builder builder = new StrictMode.VmPolicy.Builder();
StrictMode.setVmPolicy(builder.build());
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
fileUri = getOutputMediaFileUri(MEDIA_TYPE_IMAGE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);
// start the image capture Intent
activity.startActivityForResult(intent, CAMERA_CAPTURE_IMAGE_REQUEST_CODE);
}

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 Share Intent not working

Im trying to share an image, it seems to work only when the SD card is mounted or when the phone doesn't have a SD card slot. But when I dismount the SD card, it wouldn't share and it gives me two errors.
FATAL EXCEPTION: main java.lang.NullPointerException: uriString
Failed to insert image java.io.FileNotFoundException: No such file or directory
And for some reason it also saves the image that is being shared, can't seem to figured out why.
private Button button;
public void onCreate {
init();
setupView();
}
public void setupView(){
button.setOnClickListener(this);
}
public void init() {
button = (Button) findViewById(R.id.button);
}
#Override
public void onClick(View v) {
int id = v.getId();
switch (id) {
case R.id.button: {
startShare();
break;
}
public void startShare() {
Bitmap b =BitmapFactory.decodeResource(getResources(),R.drawable.m1);
Intent share = new Intent(Intent.ACTION_SEND);
share.setType("image/*");
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
b.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
String path = MediaStore.Images.Media.insertImage(getContentResolver(),
b, "Title", null);
Uri imageUri = Uri.parse(path);
share.putExtra(Intent.EXTRA_STREAM, imageUri);
startActivity(Intent.createChooser(share, "Share"));
}

try this code for share drawable image:
Uri imageUri = Uri.parse(ContentResolver.SCHEME_ANDROID_RESOURCE + "://" +
getResources().getResourcePackageName(R.drawable.ic_launcher) + '/' +
getResources().getResourceTypeName(R.drawable.ic_launcher) + '/' +
getResources().getResourceEntryName(R.drawable.ic_launcher));
Intent share = new Intent(Intent.ACTION_SEND);
share.setType("image/*");
share.putExtra(Intent.EXTRA_STREAM, imageUri);
startActivity(Intent.createChooser(share, "Share"));

sharing images from drawable

i'm trying to send images from my app, but it only sends one image (the one mentioned in the code below image_intro.
i want the app to share whatever image the user chooses.
Here is the code i used:
// Share event start
final Button share = (Button) findViewById(R.id.share);
share.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
Bitmap bitmap= BitmapFactory.decodeResource(getResources(),R.drawable.image_intro);
String path = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES)+"/LatestShare.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 bmpUri = Uri.parse("file://"+path);
Intent shareIntent = new Intent();
shareIntent = new Intent(android.content.Intent.ACTION_SEND);
shareIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
shareIntent.putExtra(Intent.EXTRA_STREAM, bmpUri);
shareIntent.setType("image/jpg");
startActivity(Intent.createChooser(shareIntent,"Share with"));
}
});
im counting in your help friends, thanks

i managed to solve it by adding these two lines:
ImageView image = (ImageView) findViewById(R.id.ba‌​ckgroundPreview);
Bitmap bitmap = ((BitmapDrawable)ima‌​ge.getDrawable()).get‌​Bitmap();
