setDefaultAudioRouteToSpeakerphone abstract method

Sets the default audio playback route.

This method is for Android and iOS only. Most mobile phones have two audio routes: an earpiece at the top, and a speakerphone at the bottom. The earpiece plays at a lower volume, and the speakerphone at a higher volume. When setting the default audio route, you determine whether audio playback comes through the earpiece or speakerphone when no external audio device is connected. In different scenarios, the default audio routing of the system is also different. See the following: Voice call: Earpiece. Audio broadcast: Speakerphone. Video call: Speakerphone. Video broadcast: Speakerphone. You can call this method to change the default audio route. After calling this method to set the default audio route, the actual audio route of the system will change with the connection of external audio devices (wired headphones or Bluetooth headphones).

• defaultToSpeaker Whether to set the speakerphone as the default audio route: true : Set the speakerphone as the default audio route. false : Set the earpiece as the default audio route.

Returns When the method call succeeds, there is no return value; when fails, the AgoraRtcException exception is thrown. You need to catch the exception and handle it accordingly.
