| |
| // The AudioPolicyInterface and AudioPolicyClientInterface classes define the communication |
| // interfaces between the platform specific audio policy manager and Android generic audio policy |
| // manager. |
| // The platform specific audio policy manager must implement methods of the AudioPolicyInterface |
| // class. |
| // This implementation makes use of the AudioPolicyClientInterface to control the activity and |
| // configuration of audio input and output streams. |
| // |
| // The platform specific audio policy manager is in charge of the audio routing and volume control |
| // policies for a given platform. |
| // The main roles of this module are: |
| // - keep track of current system state (removable device connections, phone state, |
| // user requests...). |
| // System state changes and user actions are notified to audio policy manager with methods of the |
| // AudioPolicyInterface. |
| // - process getOutput() queries received when AudioTrack objects are created: Those queries |
| // return a handler on an output that has been selected, configured and opened by the audio |
| // policy manager and that must be used by the AudioTrack when registering to the AudioFlinger |
| // with the createTrack() method. |
| // When the AudioTrack object is released, a putOutput() query is received and the audio policy |
| // manager can decide to close or reconfigure the output depending on other streams using this |
| // output and current system state. |
| // - similarly process getInput() and putInput() queries received from AudioRecord objects and |
| // configure audio inputs. |
| // - process volume control requests: the stream volume is converted from an index value |
| // (received from UI) to a float value applicable to each output as a function of platform |
| // specificsettings and current output route (destination device). It also make sure that streams |
| // are not muted if not allowed (e.g. camera shutter sound in some countries). |
| // |
| // The platform specific audio policy manager is provided as a shared library by platform vendors |
| // (as for libaudio.so) and is linked with libaudioflinger.so |
| // |
| // NOTE: by convention, the implementation of the AudioPolicyInterface in AudioPolicyManager does |
| // not have to perform any nullptr check on input arguments: The caller of this API is |
| // AudioPolicyService running in the same process and in charge of validating arguments received |
| // from incoming binder calls before calling AudioPolicyManager. |
