not able to attach excel file from assets folder

Question

I am not able to attach an excel file from assets folder using email intent in android. Can anyone please suggest what is wrong in the below code. The email opens but a message

Answer 1

First, assets/test.xlsx is not a file on the Android device. It is an asset, packaged in your APK. Hence, new File("assets/test.xlsx").

Second, even if there was a file at that path, third-party email apps cannot read it.

Either:

• Copy the file to external storage, then create a Uri to that and use it in your Intent, or

• Copy the file to internal storage and use FileProvider to serve it, or

• Use my StreamProvider to serve it straight from assets
