IMediaPlayerCacheManager

This class provides methods to manage cached media files.

enableAutoRemoveCache

Sets whether to delete cached media files automatically.

int enableAutoRemoveCache(boolean enable);

Details

If you enable this function to remove cached media files automatically, when the cached media files exceed either the number or size limit you set, the SDK automatically deletes the least recently used cache file.

Parameters

enable
Whether to enable the SDK to delete cached media files automatically:
  • true: Delete cached media files automatically.
  • false: (Default) Do not delete cached media files automatically.

Returns

getCacheDir

Gets the storage path of the cached media files.

String getCacheDir();

Details

If you have not called the setCacheDir method to set the storage path for the media files to be cached before calling this method, you get the default storage path used by the SDK.

Returns

  • The call succeeds, and the SDK returns the storage path of the cached media files.
  • < 0: Failure. See MediaPlayerReason.

getCacheFileCount

Gets the number of media files that are cached.

int getCacheFileCount();

Returns

  • ≥ 0: The call succeeds and returns the number of media files that are cached.
  • < 0: Failure. See MediaPlayerReason.

getMaxCacheFileCount

Gets the maximum number of media files that can be cached.

int getMaxCacheFileCount();

Details

By default, the maximum number of media files that can be cached is 1,000.

Returns

  • > 0: The call succeeds and returns the maximum number of media files that can be cached.
  • < 0: Failure. See MediaPlayerReason.

getMaxCacheFileSize

Gets the maximum size of the aggregate storage space for cached media files.

long getMaxCacheFileSize();

Details

By default, the maximum size of the aggregate storage space for cached media files is 1 GB. You can call the setMaxCacheFileSize method to set the limit according to your scenarios.

Returns

  • > 0: The call succeeds and returns the maximum size (in bytes) of the aggregate storage space for cached media files.
  • < 0: Failure. See MediaPlayerReason.
