How to show an image through an intent being compa

问题:

I'm trying to share an image I have previously saved on disk, sending an Intent.ACTION_SEND. The problem is that I can't find a way to be compatible with different apps, official Gmail app and TweetDeck in my case.

The image I want to share is contained in a File:

File agendaFile; 
// its path using getAbsolutePath() -> /data/data/com.mypackage/files/agenda.jpg

Option A) using Uri.fromFile

Uri agendaUri = Uri.fromFile(agendaFile); 
// the value -> file:///data/data/com.mypackage/files/agenda.jpg

Results

• Gmail, is the image attatched to the email? NO
• Tweetdeck, is the image added to the tweet message? YES

Option B) using Uri.parse

Uri agendaUri = Uri.parse(agendaFile.toURI().toString()); 
// the value -> file:/data/data/com.mypackage/files/agenda.jpg

Results

• Gmail, is the image attatched to the email? YES
• Tweetdeck, is the image added to the tweet message? NO

Finally

In both cases I send the intent like this:

final Intent intent = new Intent(android.content.Intent.ACTION_SEND);
intent.setType("image/jpg");
intent.putExtra(android.content.Intent.EXTRA_STREAM, agendaUri);
startActivity(Intent.createChooser(intent, "title"));

So, is there any other options to share an image? How is it the best way to share an image being compatible with most apps as possible?

Thanks!

try

intent.setType("image/*");

for me it works for twitter, whatsapp, bluetooth....

EDIT: full code:

Intent intent = new Intent();
        intent.setAction(Intent.ACTION_SEND);
        intent.setType("image/*");

        intent.putExtra(android.content.Intent.EXTRA_SUBJECT, title);
        intent.putExtra(android.content.Intent.EXTRA_TEXT, R.string.visita);
        Uri uri = Uri
        .parse("android.resource://com.package.xname/drawable/"
                + i);
        intent.putExtra(Intent.EXTRA_STREAM, uri);

I finally solved the problem storing the image at the MediaStore. Instead of using the URI of the File what I do is:

String agendaFilename = agendaFile.getAbsolutePath();

final ContentValues values = new ContentValues(2);
values.put(MediaStore.Images.Media.MIME_TYPE, "image/jpeg");
values.put(MediaStore.Images.Media.DATA, agendaFilename);
final Uri contentUriFile = getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);

And finally I use contentUriFile:

final Intent intent = new Intent(android.content.Intent.ACTION_SEND);
intent.setType("image/jpg");
intent.putExtra(android.content.Intent.EXTRA_STREAM, contentUriFile);
startActivity(Intent.createChooser(intent, "title"));

this code is more easy

Intent intent = new Intent(Intent.ACTION_SEND);
            intent.setData(Uri.parse("mailto:"));
            intent.putExtra(intent.EXTRA_EMAIL,"[e-mail]");
            intent.putExtra(intent.EXTRA_SUBJECT, "XXXXX");
            intent.putExtra(Intent.EXTRA_TEXT, "XXXXX");
            intent.setType("message/rfc822");
            chosser = Intent.createChooser(intent, "Enviar Email");
            intent.putExtra(intent.EXTRA_STREAM, uri);
            startActivity(chosser);

For me using FileProvider worked out. I had it set up for taking photos with built-in camera and used it for sharing (see below).

final Uri uri = FileProvider.getUriForFile(mActivity, "com.paeuba.paragonik.fileprovider", photoFile);
Intent intent = ShareCompat.IntentBuilder.from(mActivity).setType("image/jpeg").setStream(uri).createChooserIntent();
mActivity.startActivity(intent);
