Answer 1

Picasso.with(applicationContext).load(url).into(object : Target {
            override fun onBitmapLoaded(bitmap: Bitmap, from: Picasso.LoadedFrom?) {
                val bitmapPath: String =
                    MediaStore.Images.Media.insertImage(contentResolver, bitmap, "ayurved", null)
                val bitmapUri = Uri.parse(bitmapPath)
                val shareIntent = Intent(Intent.ACTION_SEND)
                shareIntent.type = "image/jpeg";
                shareIntent.putExtra(Intent.EXTRA_STREAM, bitmapUri);
                startActivity(Intent.createChooser(shareIntent, "ayurved"))
            }
            override fun onBitmapFailed(errorDrawable: Drawable?) {}
            override fun onPrepareLoad(placeHolderDrawable: Drawable?) {}
        })

Answer 2

By using createchooser you can achieve this,

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"));

Registering for the Intent

If you want your app to be listed when this Intent is called, then you have to add an intent filter in your manifest.xml file

 <intent-filter>
 <action android:name="android.intent.action.SEND" />
 <category android:name="android.intent.category.DEFAULT" />
 <data android:mimeType="image/*" />
 </intent-filter>

Answer 3

You need to use a local file. Like this:

      Uri imageUri = Uri.parse("android.resource://your.package/drawable/fileName");
      Intent intent = new Intent(Intent.ACTION_SEND);
      intent.setType("image/png");

      intent.putExtra(Intent.EXTRA_STREAM, imageUri);
      startActivity(Intent.createChooser(intent , "Share"));

If your image is on remote server download it to the device first.

Try this:

new OmegaIntentBuilder(context)
                .share()
                .filesUrls("http://stacktoheap.com/images/stackoverflow.png")
                .download(new DownloadCallback() {
                    @Override
                    public void onDownloaded(boolean success, @NotNull ContextIntentHandler contextIntentHandler) {
                        contextIntentHandler.startActivity();
                    }
                });

Here, i convert the url into imageView using asyncTask and store that into a bitmap. dont forget to add internet permission in manifest.

public class MainActivity extends AppCompatActivity  {

    @SuppressLint("WrongThread")
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Button iv1 = findViewById(R.id.shreimage);
        final ImageView imgview= (ImageView)findViewById(R.id.content_image);
        new DownloadImageTask(imgview).execute("https://sample-videos.com/img/Sample-jpg-image-50kb.jpg");
        iv1.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Drawable myDrawable = imgview.getDrawable();
                Bitmap bitmap = ((BitmapDrawable)myDrawable).getBitmap();
                try{
                    File file = new File(MainActivity.this.getExternalCacheDir(),"myImage.jpeg");
                    FileOutputStream fout = new FileOutputStream(file);
                    bitmap.compress(Bitmap.CompressFormat.JPEG,80,fout);
                    fout.flush();
                    fout.close();
                    file.setReadable(true,false);
                    Intent intent = new Intent(Intent.ACTION_SEND);
                    intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                    intent.putExtra(Intent.EXTRA_STREAM,Uri.fromFile(file));
                    intent.setType("image/*");
                    startActivity(Intent.createChooser(intent,"Share Image Via"));
                }catch (FileNotFoundException e){
                    e.printStackTrace();
                    Toast.makeText(MainActivity.this,"File Nott Found",Toast.LENGTH_SHORT).show();
                }catch (IOException e){
                    e.printStackTrace();
                }catch (Exception e){
                    e.printStackTrace();
                }
            }
        });

     }


    private class DownloadImageTask extends AsyncTask<String, Void, Bitmap> {
        ImageView bmImage;

        public DownloadImageTask(ImageView bmImage) {
            this.bmImage = bmImage;
        }

        protected Bitmap doInBackground(String... urls) {
            String urldisplay = urls[0];
            Bitmap mIcon11 = null;
            try {
                InputStream in = new java.net.URL(urldisplay).openStream();
                mIcon11 = BitmapFactory.decodeStream(in);
            } catch (Exception e) {
                Log.e("Error", e.getMessage());
                e.printStackTrace();
            }
            return mIcon11;
        }

        protected void onPostExecute(Bitmap result) {
            bmImage.setImageBitmap(result);
        }
    }
}

   share.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {

            if (bmpUri != null) {

//for oreo add below code in manifest under application tag

 <provider
        android:name=".utility.GenericFileProvider"
        android:authorities="${applicationId}.your package 
     name.utility.GenericFileProvider"
        android:exported="false"
        android:grantUriPermissions="true">
        <meta-data
            android:name="android.support.FILE_PROVIDER_PATHS"
            android:resource="@xml/provider_paths" />
    </provider>

---

create class that extends FileProvider

public class MyFileProvider extends FileProvider {

}

---

for oreo add this code

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            bmpUri = FileProvider.getUriForFile(this, 
      this.getApplicationContext().getPackageName() + 
    ".your package name.GenericFileProvider", file);
        } else {
            bmpUri = Uri.fromFile(file);
        }

---

finally add provider_paths.xml in res/xml 

   <paths xmlns:android="http://schemas.android.com/apk/res/android">
   <external-path name="external_files" path="."/>
   </paths>

thats all
