试图有目的地共享mp3，但文件扩展名不包括在内

Question

Uri clipUri = Uri.parse("android.resource://com.packagename.community/raw/" + rawname);
Intent shareIntent = new Intent();
shareIntent.setAction(Intent.ACTION_SEND);
shareIntent.putExtra(Intent.EXTRA_STREAM, clipUri);
shareIntent.setType("audio/mpeg");
startActivity(Intent.createChooser(shareIntent, getResources().getText(R.string.send_to)));

This code almost works, I can successfully send the clip to another app (dropbox for example) and everything is fine with the file except it lacks a .mp3 extension.

Welcome to StackOverflow! StackOverflow is for programming questions, and this is not a question.

I am going to interpret your non-question as:

Why, when I use a Uri that does not have a file extension, is a file extension not magically added by file extension elves?

That's because Android lacks file extension elves.

If you want to have a file extension in your Uri , you need to put one there. And, since there is no syntax that I am aware of that will give an android.resource:// Uri a file extension, your choices are:

1. Share a file, instead of a resource

2. Create a ContentProvider that will serve up the resource via openFile in response to some Uri that does indeed have your desired file extension

3. Live without the file extension

4. Don't share the resource
