POResuming video after back button was pressed
text
Body
copied!<p>I am writing an app for movies on my son's tablet and periodically he hits the back or home button. Being 2 yrs old he gets frustrated because he lost the video he was watching. I am able to save the state when he hits the home button so when he goes back into the app the movie resumes. Unfortunately, no matter how I try to set the back button, it always starts at the beginning again. </p> <p>I have tried the onBackPressed and KeyDown Methods, but they done seem to work. Am I missing something?</p> <p>I appreciate any help and I apologize if this is a duplicate and I not finding it.</p> <pre><code>package com.example.toddlerplayer; import java.io.File; import java.util.ArrayList;
