Media (codenameone-core 7.0.44 API)

All Known Subinterfaces:

AsyncMedia

All Known Implementing Classes:

AbstractMedia
```
public interface Media
```
Media control interface allows for media playback, recording. To get an instance of this interface (implemented by the native port) see the MediaManager class.

The sample code below demonstrates simple video playback.

The code below demonstrates capturing audio using the Capture API and playing back audio files using the Media API:

The code below demonstrates capturing audio and playing back audio using the Media, MediaManager and MediaRecorderBuilder APIs, as alternative and more customizable approach than using the Capture API:

void setNativePlayerMode(boolean nativePlayer)
```
    By calling this the Media (if it's a Video) will be played full screen on the native Player of the device. Native playing assumes getVideoComponent() hasn't been called on this Media unexpected behaviour may occur if getVideoComponent() has been called and the Component is placed on a Form. Some platforms such as BlackBerry is able to play video only on the native player on those platforms isNativePlayerMode() will always return true
  - isNativePlayerMode
```
boolean isNativePlayerMode()
```
    Returns true if this Video Media is in Native player mode. Some platforms such as BlackBerry is able to play video only on the native player on those platforms isNativePlayerMode() will always return true If Media supports native playing by calling to play() the video will start playing in the native player in full screen.
    
    Returns:
    
    true if the player is in native mode
  - setVariable
```
void setVariable(String key,
                 Object value)
```
    Allows for platform specific enhancements for media playback
    
    Parameters:
    
    key - the key to set to the media that is platform specific
