sound replaying

[cweng777]

Hi, at the "SAVED RECORDINGS" screen, if the user's permission is not granted, the first time to pause during the replaying will fail.
Here is the bug report:
Environment
Android mobile phone/emulator
App version : 2.0.2
Device model : Galaxy J7, emulator
Android version : 6.0.1, 9
Steps to reproduce
Go to setting-> find the SoundRecorder app-> remove the storage permission ->
open the SoundRecorder app->select the "SAVED RECORDINGS" screen ->
select one sound file->click play button to replay as the dialog shows ->
The system will ask the permission, click "allow" ->
click the pause button
Expected Result
Replaying stops
Actual Result
Replaying continues

I fixed it by changing one variable in PlaybackFragment.
There is one control variable "isPlaying" which should be true after the user gives the storage permission. Otherwise, the first time to pause will fail.
Here is the video of my change:
