Open an Image in Internal Storage Using Content Provider

Question

Let's say I package an image with my app and I want to open it with the default image viewer/whatever image viewer the user has chosen to be the default. How would I do that?

There's already this post: Open an image using URI in Android's default gallery image viewer but many of the answers are obsolete because due to the introduction of android N, a content provider must be used.

The only answer I can find is this one:

File file = ...;
final Intent intent = new Intent(Intent.ACTION_VIEW)//
                                    .setDataAndType(VERSION.SDK_INT >= VERSION_CODES.N ?
                                                    android.support.v4.content.FileProvider.getUriForFile(this,getPackageName() + ".provider", file) : Uri.fromFile(file),
                            "image/*").addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);

but, according to the author of this solution, this code only works for images stored externally, not ones that may be packaged with my app.

Answer 1

You won't be able to open an image packaged with the app (in drawable or whatever resources) through an external application. You should first copy it into (at least) an internal file storage. After that you can implement a FileProvider to provide access to this file.

Let me know if you need more details on this. Hope it helped.
