Android: Share Simple Text As File/attachment

I have an app that collects some info and allows the user to share it using Android's Intent framework. So far, it shares the report as plain text: using putExtra(Intent.EXTRA_TEXT

Solution 1:

Use FileProvider to share a file that is not publicly accessible. Check out Setting Up File Sharing for a short tutorial.

Sending text as an email attachment is a bit tricky though. You can't use text/plain as type because that would imply the data is supplied in EXTRA_TEXT. But text in this extra will end up in the email body, not in an attachment.

What should work is the following:

UrifileUri= FileProvider.getUriForFile(context, "org.example.provider.authority", reportFile);

IntentshareIntent=newIntent(Intent.ACTION_SEND);
shareIntent.setType("*/*");
shareIntent.putExtra(Intent.EXTRA_STREAM, fileUri);

startActivity(Intent.createChooser(shareIntent, null)); 

You should also make sure that FileProvider.getType() returns text/plain for the report file. The easiest way to accomplish this is by using .txt as file extension and FileProvider will automatically do the right thing.
