getCacheDirectory

public static File getCacheDirectory(android.content.Context context)

参数:

context - Application context

返回:

Cache directory.
NOTE: Can be null in some unpredictable cases (if SD card is unmounted and Context.getCacheDir() returns null).

getCacheDirectory

public static File getCacheDirectory(android.content.Context context,
                                     boolean preferExternal)

Returns application cache directory. Cache directory will be created on SD card ("/Android/data/[app_package_name]/cache") (if card is mounted and app has appropriate permission) or on device's file system depending incoming parameters.

参数:

preferExternal - Whether prefer external location for cache

返回:

Cache directory.

getIndividualCacheDirectory

public static File getIndividualCacheDirectory(android.content.Context context)

Returns individual application cache directory (for only image caching from ImageLoader). Cache directory will be created on SD card ("/Android/data/[app_package_name]/cache/uil-images") if card is mounted and app has appropriate permission. Else - Android defines cache directory on device's file system.

参数:

context - Application context

public static File getIndividualCacheDirectory(android.content.Context context,
                                               String cacheDir)

Returns individual application cache directory (for only image caching from ImageLoader). Cache directory will be created on SD card ("/Android/data/[app_package_name]/cache/uil-images") if card is mounted and app has appropriate permission. Else - Android defines cache directory on device's file system.

参数:

context - Application context

返回:

Cache directory

getOwnCacheDirectory

public static File getOwnCacheDirectory(android.content.Context context,

参数:

context - Application context

cacheDir - Cache directory path (e.g.: "AppCacheDir", "AppDir/cache/images")

返回:

Cache directory

getOwnCacheDirectory
