Android - how to open image in gallery with delete option

I use following code to open an image in the gallery:
public void onItemClicked(PictureItem item){
Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
Uri imageUri = FileProvider.getUriForFile(getApplicationContext(), "myapp.fileprovider", new File(item.uri.getPath()));
intent.setDataAndType(imageUri, "image/*");
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
startActivity(intent);
}
This shows my photo in the gallery, but in a 'read-only' mode. I want to be able to delete the image from there, just as if I opened it directly in the gallery.
Which action do I have to use for that? I do not want to use pick, just normal view with the option to delete. I tried ACTION_EDIT but it's not supported (and not quite the right choice neither ...).

I use following code to open an image in the gallery
First, there are hundreds, if not thousands, of "gallery" apps available for Android.
Second, your code simply asks to view an image (with a broken Intent due to your wildcard MIME type). There is no requirement for the app that responds to be a "gallery" app.
I want to be able to delete the image from there, just as if I opened it directly in the gallery.
Then implement that yourself, in your own app, and get rid of the ACTION_VIEW Intent.
Which action do I have to use for that?
There is no Intent action that says "please display this image, but only if you are a gallery app, and, oh, by the way, you must offer a delete option", which appears to be what you want.

Proper solution to pick/click an image on Android

As the title suggests, i'm having an option to upload an image in my app.
I would like to have two options: Click a new picture & Select from gallery.
Gallery selection is working fine on all devices using this code:
Intent in = new Intent();
in.setType("image/*");
in.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(in, getString(R.string.selectpicture)), 100);
The problem is with Click a new picture.
I want to use other camera apps installed on the device to get the image.
This code should save the image user clicks at the specified path.
Intent m_intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
imageUri = getImageUri();
m_intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
startActivityForResult(m_intent, REQUEST_IMAGE_CAPTURE);
But what happens is, the EXTRA_OUTPUT is not respected by all camera apps.
Also if memory is low, my app is killed by the system which makes things more complicated.
So, what's the best way to enable user to click a new picture and get the image path in my app?
If using third party libraries is better, which one's are reliable?

the EXTRA_OUTPUT is not respected by all camera apps.
Any time you delegate anything to a third party app, you can run into problems.
Also if memory is low, my app is killed by the system which makes things more complicated.
You need to handle this anyway. Save the value you put in EXTRA_OUTPUT in the saved instance state Bundle.
what's the best way to enable user to click a new picture and get the image path in my app?
If you wish to stick with ACTION_IMAGE_CAPTURE, I'd go with this triage:
If there is an image in the location you provided to EXTRA_OUTPUT, use it
If not, and getData() on the Intent given to you in onActivityResult() returns a Uri (and not null), use that (and if you truly need a File, use ContentResolver and openInputStream() with the Uri and copy the contents into your own file)
If neither are true, and getParcelableExtra("data") returns a value, save that Bitmap to a file
If none of those are true, suggest to the user to get a different camera app, perhaps pointing them to one that you have tried and know works
Or, take the picture yourself, directly or using a library like mine.

What's the proper way to share via Intent.createChooser

The problem is I have an article that want to share to other apps, and I want to let the user to choose which app to share to. What I want to share is basically:
the title of the article
the URL of the article
the article content as HTML
the URL with some extra text (such as 'http://foo.com/article share from #FooApp')
All of these fields are optional, but I want to share at least one of them.
Such as when share via SMS or twitter, I want to set the content to part 4. when share via Facebook, I want to set 1, 2, 3 together. And when share via email, I want to set subject as 1 and message as 4.
I know (correct me if I'm wrong) every target intent receiver has it's own logic to pick up the fields it needed. So I want to provide as much information as possible and I wrote the following code:
String message = article.getURL() + " #FooApp";
Intent intent = new Intent().setData(Uri.parse(article.getURL())
.putExtra(Intent.EXTRA_SUBJECT, article.getTitle())
.putExtra(Intent.EXTRA_TEXT, message)
.putExtra(Intent.EXTRA_HTML_TEXT, article.getHTML())
.putExtra("sms_body", message)
...
.setType(HTTP.PLAIN_TEXT_TYPE);
startActivity(Intent.createChooser(intent, "Share to"));
But the problem is, it seems like a trick between setData, putExtra, setType.
For some apps appear in the chooser dialog, when I choose, the confirm share window (of that app) display nothing that I set to the intent. (for some other apps they just say failed to fetch resource)
For the putExtra part, when I add or remove some putExtra code, the target intent receivers diff a lot than I expected.
So the question is: am I doing it the wrong way? Are there some guideline for this problem?

Tutorial / reference to launch ACTION_EDIT with image and return image

I'm writing an app that uses the camera. I want to lauch an intent to allow users to annotate the resulting image with lines and text, AND I would like to provide the user with a list of appropriate image editting apps they can use, but I'm coming across these problems:
1. Not all image editting apps appear in the list when I perform this code:
editIntent = new Intent();
editIntent.setAction(Intent.ACTION_EDIT);
Uri imageToEditUri = selectedPhotoLocation; // Uri of existing photo
String imageToEditMimeType = "image/*";
editIntent.setDataAndType(imageToEditUri, imageToEditMimeType);
startActivityForResult(Intent.createChooser(editIntent,"Edit Image"), IMPLICIT_EDIT_IMAGE);
Is there a way to get a list of apps that will respond to Intent.ACTION_EDIT?
2. PS Express is the only app I've found that returns the Uri of the editted image in the data.getDate() Uri returned to OnActivityResult(), with other apps the user is forced to save, remember the location, and reselect the editted image.
Is there a way to know what apps return the Uri of the image to OnActivityResult()

Not all image editting apps appear in the list when I perform this code
Just because an app implements image editing does not necessarily mean that it is set up to allow third parties to link to their image-editing activities.
Is there a way to get a list of apps that will respond to Intent.ACTION_EDIT?
If you mean that you want to do this programmatically at runtime, see Jedil's answer.
Is there a way to know what apps return the Uri of the image to OnActivityResult()
No, except for those applications that have documentation on how developers should integrate with them.

First question answer:
try queryIntentActivities
Intent editIntent = new Intent(android.content.Intent.ACTION_EDIT);
List<ResolveInfo> resInfo = getPackageManager().queryIntentActivities(editIntent, 0);

modified android ACTION_VIEW intent

I execute the following code:
Uri uri =
Uri.withAppendedPath(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
imageIdStr); Intent intent = new
Intent();
intent.setAction(android.content.Intent.ACTION_VIEW);
intent.setData(uri);
activity.startActivity(intent);
which opens the image viewer activity but I don't want to see the navigation arrows as well as the items in the menu. I only want the zoom controls. Is it possible to have it like that ?

That depends on the application that's actually displaying the image. On Android 2.0 and older, it's probably the Gallery app. On many Android 2.1+ apps, it's probably CoolIris' gallery. If the user has one of the many gallery apps from the market installed, it's up to those apps. I highly doubt there's a standardized extra to control that.
If you're really concerned about what the image display looks like, then you should handle that yourself. If you're really just trying to display an image (and maybe add pinch-zoom support?), it's a reasonable scope.
