Android imitation wechat voice recording function

This example shares the specific code of Android imitation wechat recording voice for your reference. The specific contents are as follows

preface

I divided the recording into two parts

1. UI interface, pop-up window to read seconds 2. A class (including start, stop and create file name functions)

Part I

Due to the 6.0 permission problem, click the button to apply for permission, and a window will pop up. How to apply for permission

This is selected from my code. It should be possible to add permissions.
