Android

Android specific features

  • By default, MultimediaPlay is a blocking function until the control is ready to play the file.
  • The MultimediaNonBlocking constant is used to perform a non-locking load operation. In this case, the call to a Multimedia function (MultimediaPosition, ...) will fail as long as the media file is not loaded by the control.
  • The non-locking load operations are recommended when using media files not found on the device (online video for example).
  • If <File to play> is the URL of a video on a "https" web server, the "android.permission.INTERNET" permission must be added in the application generation wizard.
  • In Android, all the formats supported by the OS can be played (wav, mp3, 3gp, ogg, ...). A summary of the supported audio and video files is available from the following address: http://developer.android.com/guide/appendix/media-formats.html. Remark: Android does not support 32-bit wav files.
