Android: Intent.ACTION_SEND with EXTRA_STREAM doesn't attach any image when choosing Gmail app on htc Hero

On the Emulator with a default mail-app all works fine. But I have no attach when I’am receiving a mail which I’ve sent from my Hero using a Gmail app. The default Mail app on the hero works fine.

How can I make this code works with Gmail app on Hero?

    in Logs I see the following:

    For me the problem was solved with the following lines of code:

    Bitmap screenshot = Bitmap.createBitmap(_rootView.getWidth(), _rootView.getHeight(), Bitmap.Config.RGB_565);
    _rootView.draw(new Canvas(screenshot));
    
    String path = Images.Media.insertImage(getContentResolver(), screenshot, "title", null);
    Uri screenshotUri = Uri.parse(path);
    
    final Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
    emailIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    emailIntent.putExtra(Intent.EXTRA_STREAM, screenshotUri);
    emailIntent.setType("image/png");
    
    startActivity(Intent.createChooser(emailIntent, "Send email using"));
    

    The key thing is that I’m saving the screen-shot to the media library and then it can successfully send a file from there.

    getFileStreamPath() or openFileOutput() will create files in a private directory that is inaccessible to other apps (i.e. Gmail). Use external storage to create publicly-accessible files:

    private static final int REQUEST_SHARE = 39714;
    
    private File png = null;
    
    private void startSendIntent() {
        png = new File(new File(Environment.getExternalStorageDirectory(), "Pictures"), getString(R.string.file_name));
    
        FileOutputStream out = null;
        try {
            out = new FileOutputStream(png);
            bitmap.compress(Bitmap.CompressFormat.PNG, 100, out);
            out.flush();
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            try {
                if (out != null) out.close();
            }
             catch (IOException ignore) {}
            }
            final Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
            emailIntent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(png));
            emailIntent.setType("image/png");
            startActivityForResult(Intent.createChooser(emailIntent, getString(R.string.send_intent_name)), REQUEST_SHARE);
        }
    }
    

    This will not work when the external storage is unavailable, like when it is mounted as a USB drive. See the Storage API Guide for more about detecting whether external storage is available.

    If your minimum API level is 8 or above, you can use Context.getExternalCacheDir() or Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES) as the parent directory.

    Unless you end up using getExternalCacheDir(), make sure you use a unique filename to prevent one of the users’ files from accidentally getting overwritten.

    Finally, you can override onActivityResult() to delete the file after the share operation completes:

    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    
        if(requestCode == REQUEST_SHARE) {
            if(this.png == null) {
                return;
            }
    
            this.png.delete();
        }
    }
    

    I had the same symptoms. In my case it was because I was initially saving the attachment with the permissions MODE_PRIVATE. As soon as I changed it to MODE_WORLD_READABLE it seems Gmail was then able to access the file and send the attachment properly. Although I see in your code snippet you were using MODE_WORLD_READABLE … weird.
