Control the *sound of Android (Nishimy)*

Android volume settings are a feature that varies from device to device. Silent mode in particular varies widely depending on the device. In some cases, you may need to have certain permissions granted to unmute the device. This session will explain what kind of differences exist in how to set the device volume for each device.

Also, when controlling the volume of Android, it is necessary to use appropriately some attributes (AudioAttributes). I will introduce the different types of AudioAttributes and explain which Audio Attributes should be used in which situations. and which AudioAttributes should be used in which situations. Then, I will explain what you should pay attention to when controlling the volume.

As you can see, controlling sound in Android is surprisingly complex. In this session, I will talk about how to successfully control sound from the application side.
