View content = findViewById(R.id.full_image_view);
content.setDrawingCacheEnabled(true);

Bitmap bitmap = content.getDrawingCache();
File root = Environment.getExternalStorageDirectory();
File cachePath = new File(root.getAbsolutePath() + "/DCIM/Camera/image.jpg");
try {
       cachePath.createNewFile();
       FileOutputStream ostream = new FileOutputStream(cachePath);
       bitmap.compress(CompressFormat.JPEG, 100, ostream);
       ostream.close();
 } catch (Exception e) {
       e.printStackTrace();
 }

Intent share = new Intent(Intent.ACTION_SEND);
share.setType("image/*");
share.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(cachePath));
startActivity(Intent.createChooser(share,"Share via"));
