        Picasso.with(getApplicationContext()).load(url).into(new Target() {
            @Override public void onBitmapLoaded(Bitmap bitmap, Picasso.LoadedFrom from) {
                Intent i = new Intent(Intent.ACTION_SEND);
                i.setType("*/*");
                i.putExtra(Intent.EXTRA_STREAM, getLocalBitmapUri(bitmap));
                i.putExtra(Intent.EXTRA_TEXT, name.getText().toString()+ "\n" +productimage);
                startActivity(Intent.createChooser(i, "Share Image"));
            }
            @Override public void onBitmapFailed(Drawable errorDrawable) { }
            @Override public void onPrepareLoad(Drawable placeHolderDrawable) { }
        });
    }
    public Uri getLocalBitmapUri(Bitmap bmp) {
        Uri bmpUri = null;
        try {
            File file =  new File(getExternalFilesDir(Environment.DIRECTORY_PICTURES), "share_image_" + System.currentTimeMillis() + ".png");
            FileOutputStream out = new FileOutputStream(file);
            bmp.compress(Bitmap.CompressFormat.PNG, 90, out);
            out.close();
            //bmpUri = Uri.fromFile(file);
            bmpUri=FileProvider.getUriForFile(getApplication(),BuildConfig.APPLICATION_ID+".provider",file);
        } catch (IOException e) {
            e.printStackTrace();
        }
        return bmpUri;
    }

Answer 1

you should add an intent filter in manifest file. An intent filter should contain the following elements and attribute values;

Define ACTION_VIEW intent action so that the intent filter can be reached from Google Search.

<action android:name="android.intent.action.VIEW" />

We should include the BROWSABLE category in order to be accessible from a web browser. We should also have DEFAULT category for responding to implicit intents

<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />

Lastly, We should define one or more tags. Each of these tags represents a URI format that resolves to the activity. The following example represents a simple data tag for test.com Android app.

 <data
        android:host="test.com"
        android:scheme="https" />

How to read data from incoming intents

When you define your intent filter that can handle specific URLs, the system can start your activity via that intent filter.

Intent intent = getIntent();
Uri data = intent.getData();

if you pass the query parameter as test.com?productID=123 you can retrieve it from

data.getQueryParameter("productID");
