How do I share Images from Firebase Database?

I have created database and there is Url of image and I want to show that image in my app which is working but now I want share that image in Whatsapp etc. Now what I need to change there as I didn't get any idea,how to do it?
Here is my Code:
#Override
public void onBindViewHolder(#NonNull final myViewHolder holder, int position) {
Picasso.get().load(mdata.get(holder.getAdapterPosition()).getImage()).into(holder.imgView);
holder.shareBtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent intent;
Bitmap bitmap = BitmapFactory.decodeResource(context.getResources(), holder.imgView.getId());
String path = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES) +"/share.png";
FileOutputStream 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 = new Intent(Intent.ACTION_SEND);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.putExtra(Intent.EXTRA_STREAM, bmpUri);
intent.setType("image/jpeg");
intent.putExtra(Intent.EXTRA_TEXT," Hello Your's Images ");
context.startActivity(Intent.createChooser(intent, " Share Images Via"));

You can do it using uri, and try to implement the next code:
Uri imageUri = Uri.parse(pictureFile.getAbsolutePath());
Intent shareIntent = new Intent();
shareIntent.setAction(Intent.ACTION_SEND);
//Send to Whattssap
shareIntent.setPackage("com.whatsapp");
//Even you can add text to the image
shareIntent.putExtra(Intent.EXTRA_TEXT, picture_text);
shareIntent.putExtra(Intent.EXTRA_STREAM, imageUri);
shareIntent.setType("image/jpeg");
shareIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
try {
startActivity(shareIntent);
} catch (android.content.ActivityNotFoundException ex) {
ToastHelper.MakeShortText("Whatsapp have not been installed.");
}
And that's all

How to share GIF image in Whatsapp programmatically in Android?

WhatsApp have added new feature display GIF.
if any one know how to share GIF in whatsapp then let me know

Try this....
private void shareGif(String resourceName){
String baseDir = Environment.getExternalStorageDirectory().getAbsolutePath();
String fileName = "sharingGif.gif";
File sharingGifFile = new File(baseDir, fileName);
try {
byte[] readData = new byte[1024*500];
InputStream fis = getResources().openRawResource(getResources().getIdentifier(resourceName, "drawable", getPackageName()));
FileOutputStream fos = new FileOutputStream(sharingGifFile);
int i = fis.read(readData);
while (i != -1) {
fos.write(readData, 0, i);
i = fis.read(readData);
}
fos.close();
} catch (IOException io) {
}
Intent shareIntent = new Intent(android.content.Intent.ACTION_SEND);
shareIntent.setType("image/gif");
Uri uri = Uri.fromFile(sharingGifFile);
shareIntent.putExtra(Intent.EXTRA_STREAM, uri);
startActivity(Intent.createChooser(shareIntent, "Share Emoji"));
}
For share gif on whatsapp
/* Intent shareIntent = new Intent();
shareIntent.setAction(Intent.ACTION_SEND);
shareIntent.setPackage("com.whatsapp");
shareIntent.putExtra(Intent.EXTRA_TEXT,title + "\n\nLink : " + link );
shareIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse(sharePath));
shareIntent.setType("image/*");
startActivity(shareIntent);*/

You just need to set the type of image intent as gif like below
Intent shareIntent = new Intent(android.content.Intent.ACTION_SEND);
shareIntent.setType("image/gif");

Image only Shared with Whatsapp but not with other apps in Android

I am trying to share image using intent. Here is the method that i created
public void shareImg(int fileNum) //Consider fileNum=R.drawable.img
{
Uri uri= Uri.parse("android.resource://"
+ context.getPackageName() + "/" + fileNum);
Intent share=new Intent();
share.setAction(Intent.ACTION_SEND);
share.setType("image/*");
share.putExtra(Intent.EXTRA_STREAM, uri);
share.putExtra(Intent.EXTRA_TEXT, "Sent Via ---");
Intent chooser= Intent.createChooser(share, "Share Via");
context.startActivity(chooser);
}
The image is shared properly with Whatsapp with caption. But when I try to share app with Gmail, Messenger, etc it gives error shown in Toast.
For eg.
Gmail says : Can't attach empty file
Messenger says : Failed to convert to image

You can share image using share intent, but you've to decode image to a localized Bitmap
Intent intent = new Intent(Intent.ACTION_SEND);
intent.putExtra(Intent.EXTRA_TEXT, "Hey view/download this image");
String path = Images.Media.insertImage(getContentResolver(), loadedImage, "", null);
Uri screenshotUri = Uri.parse(path);
intent.putExtra(Intent.EXTRA_STREAM, screenshotUri);
intent.setType("image/*");
startActivity(Intent.createChooser(intent, "Share image via..."));
loadedImage is the Path of image

Here is the steps you can perform.
Step 1. First create bitmap from drawable
Drawable d = ImagesArrayList.get(0);
Bitmap bitmap = ((BitmapDrawable)d).getBitmap();
Step 2. Save Bitmap to File
FileOutputStream out = null;
String filename = Environment.getExternalStorageDirectory() + File.separator + "temporary_file.jpg";
try {
out = new FileOutputStream(filename);
bitmap.compress(Bitmap.CompressFormat.PNG, 100, out); // bmp is your Bitmap instance
// PNG is a lossless format, the compression factor (100) is ignored
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
if (out != null) {
out.close();
}
} catch (IOException e) {
e.printStackTrace();
}
}
Step 3. Share this image File with fileurl. Share the Image same as you sharing gallery image.
Complete Answer
Bitmap bitmap= BitmapFactory.decodeResource(getResources(),R.drawable.xxxx); // your resource ID here
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"));

Sharing images in other application

I have application with images and I want share image which is choosen by user in some other application. From other question here I know that I must put the image in public place so it can be accesed by other application. But I still get error "no application can perform this action" any idea where am I doing mistake?
Code for copying image to SD card:
String path = Environment.getExternalStorageDirectory().toString();
File file = new File(path,String.valueOf(idOfImage));
if (!file.exists())
{
Bitmap myBitmap = BitmapFactory.decodeResource(getResources(),idOfImage);
FileOutputStream out = null;
try {
out = new FileOutputStream(file);
myBitmap.compress(Bitmap.CompressFormat.PNG, 90, out);
} catch (Exception e)
{
e.printStackTrace();
} finally {
try {
if (out != null)
{
out.close();
}
} catch (IOException e)
{
e.printStackTrace();
}
}
Code for sending the intent and picking chooser:
Intent shareIntent = new Intent();
shareIntent.setAction(Intent.ACTION_SEND);
Uri uri = Uri.fromFile(file);
shareIntent.putExtra(Intent.EXTRA_STREAM, uri);
StartActivity(Intent.createChooser(shareIntent,getResources().getText(R.string.share)));
Thanks for answers.
EDIT: Works fine when sharingIntent.setType("image/png"); lane added, with Gmail and G+ , but doesnt work with Messengers FB and others.

try this code
Intent shareIntent = new Intent(android.content.Intent.ACTION_SEND);
shareIntent.setType("image/*");
shareIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, (String)
v.getTag(R.string.app_name));
shareIntent.putExtra(Intent.EXTRA_STREAM, imageUri); // put your image URI
PackageManager pm = v.getContext().getPackageManager();
List<ResolveInfo> activityList = pm.queryIntentActivities(shareIntent, 0);
for (final ResolveInfo app : activityList)
{
if ((app.activityInfo.name).contains("facebook"))
{
final ActivityInfo activity = app.activityInfo;
final ComponentName name = new ComponentName(activity.applicationInfo.packageName, activity.name);
shareIntent.addCategory(Intent.CATEGORY_LAUNCHER);
shareIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED);
shareIntent.setComponent(name);
v.getContext().startActivity(shareIntent);
break;
}
}
Edit 1
Intent shareIntent = new Intent();
shareIntent.setAction(Intent.ACTION_SEND);
shareIntent.putExtra(Intent.EXTRA_STREAM,Uri.fromFile(new File(filePath))); //optional//use this when you want to send an image
shareIntent.setType("image/jpeg");
shareIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
startActivity(Intent.createChooser(shareIntent, "send"));
use this code i tried it and it works here at my side

Intent sharingIntent = new Intent(Intent.ACTION_SEND);
Uri screenshotUri = Uri.parse(path);
sharingIntent.setType("image/png");
sharingIntent.putExtra(Intent.EXTRA_STREAM, screenshotUri);
startActivity(Intent.createChooser(sharingIntent, "Share image using"));

Android: send an email with an image from an ImageView

I'm new here on stackoverflow. I have a little problem with my Android app, expecially with an ImageView that triggers an event on tap. This event opens an email client with some pre-written text and it should attach the image of the Image. I already know that the image should be converted into a bitmap before, then compressed and send it to the email client, but unfortunatly I'm not an Android/Java expert so I can't find how to do that. This is the code of the email method:
new code below
Where I have to replace "String imageURI = null;" with what the email needs as image. Thank you all!
EDIT:
I managed to edit my code to this, that gives no errors:
public void sendMail(ImageView image){
Intent i = new Intent(Intent.ACTION_SEND);
int imageURI = R.drawable.img1;
i.setType("text/plain");
i.putExtra(Intent.EXTRA_EMAIL , new String[]{"destinatario#globelife.biz"});
i.putExtra(Intent.EXTRA_SUBJECT, "Oggetto");
i.putExtra(Intent.EXTRA_TEXT , "Globelife");
i.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
i.setType("image/jpeg");
i.putExtra(Intent.EXTRA_STREAM, Uri.parse("android.resource://"+getPackageName()+"/"+imageURI));
try {
startActivity(Intent.createChooser(i, "Send mail..."));
} catch (android.content.ActivityNotFoundException ex) {
Toast.makeText(Test01Activity.this, "Non sono presenti app per l'invio di e-mails.", Toast.LENGTH_SHORT).show();
}
}
But I need to change "int imageURI = R.drawable.img1;" to "int imageURI = ImageView.src;" or something like that

try this
ImageView iv = (ImageView) findViewById(R.id.splashImageView);
Drawable d =iv.getBackground();
BitmapDrawable bitDw = ((BitmapDrawable) d);
Bitmap bitmap = bitDw.getBitmap();
File mFile = savebitmap(bitmap);
and then
Uri u = null;
u = Uri.fromFile(mFile);
Intent emailIntent = new Intent(Intent.ACTION_SEND);
emailIntent.setType("image/*");
emailIntent.putExtra(Intent.EXTRA_SUBJECT, "Hello...");
// + "\n\r" + "\n\r" +
// feed.get(Selectedposition).DETAIL_OBJECT.IMG_URL
emailIntent.putExtra(Intent.EXTRA_TEXT, "Your tsxt here");
emailIntent.putExtra(Intent.EXTRA_STREAM, u);
startActivity(Intent.createChooser(emailIntent, "Send email..."));
and savebitmap method
private File savebitmap(Bitmap bmp) {
String extStorageDirectory = Environment.getExternalStorageDirectory().toString();
OutputStream outStream = null;
File file = new File(extStorageDirectory, temp + ".png");
if (file.exists()) {
file.delete();
file = new File(extStorageDirectory, temp + ".png");
}
try {
outStream = new FileOutputStream(file);
bmp.compress(Bitmap.CompressFormat.PNG, 100, outStream);
outStream.flush();
outStream.close();
} catch (Exception e) {
e.printStackTrace();
return null;
}
return file;
}

Intent i = new Intent(Intent.ACTION_SEND);
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
i.setType("image/jpg");
i.putExtra(Intent.EXTRA_STREAM, Uri.parse("file:///sdcard/Pictures/
image.jpg"));
startActivity(i);

Intent intent=new Intent(Intent.ACTION_SEND);
String[] recipients={"destinatario#domain.com"};
intent.putExtra(Intent.EXTRA_EMAIL, recipients);
intent.putExtra(Intent.EXTRA_SUBJECT, "Oggetto");
intent.putExtra(Intent.EXTRA_TEXT , "Testo");
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
intent.setType("image/png");
intent.putExtra(Intent.EXTRA_STREAM,Uri.parse(“file///sdcard/Images/your_image.jpg”));//or you can pass the path of your image
startActivity(Intent.createChooser(intent, "Send mail"));

//re move the String imageURI=null;
public void sendMail(ImageView image){
Intent i = new Intent(Intent.ACTION_SEND);
Uri pngImageUri = Uri.parse(image);
i.setType("image/png");//change here with image/png
i.putExtra(Intent.EXTRA_EMAIL , new String[]{"destinatario#domain.com"});
i.putExtra(Intent.EXTRA_SUBJECT, "Oggetto");
i.putExtra(Intent.EXTRA_TEXT , "Testo");
i.putExtra(Intent.EXTRA_STREAM, pngImageUri);
