Methods Summary
public static SoundTriggerModuleattachModule(int moduleId, android.hardware.soundtrigger.SoundTrigger$StatusListener listener, android.os.Handler handler)
Get an interface on a hardware module to control sound models and recognition on this module.

param
moduleId Sound module system identifier {@link ModuleProperties#id}. mandatory.
param
listener {@link StatusListener} interface. Mandatory.
param
handler the Handler that will receive the callabcks. Can be null if default handler is OK.
return
a valid sound module in case of success or null in case of error.

public static native intlistModules(java.util.ArrayList modules)
Returns a list of descriptors for all harware modules loaded.

param
modules A ModuleProperties array where the list will be returned.
return
- {@link #STATUS_OK} in case of success - {@link #STATUS_ERROR} in case of unspecified error - {@link #STATUS_PERMISSION_DENIED} if the caller does not have system permission - {@link #STATUS_NO_INIT} if the native service cannot be reached - {@link #STATUS_BAD_VALUE} if modules is null - {@link #STATUS_DEAD_OBJECT} if the binder transaction to the native service fails
