How to open an image file (from download folder) using intent directly from your Android App?

In this video it shows the steps to implement the intent code which can open an image file directly from your Android App. The intent will invoke the default application in the device associated with the file type to open the file.

Same concept can be used to open other file types such as MS Word, PDF, text, etc. We have to ensure we pass the correct MIME type of the file to open the respective file. In the below link it lists down the MIME Type of most of the file types/ extensions: https://programmerworld.co/blogs/file-mime-types-for-intent-setdata-android-studio/
