- Method Detail
  - getPhotoCacheDir
```
@Nullable
public static File getPhotoCacheDir(Context context)
```
    Returns a directory with a default name in the private cache directory of the application to use to store retrieved media and thumbnails.
    
    Parameters:
    
    context - A context.
    
    See Also:
    
    getPhotoCacheDir(android.content.Context, String)
  - getPhotoCacheDir
```
@Nullable
public static File getPhotoCacheDir(Context context,
                                              String cacheName)
```
    Returns a directory with the given name in the private cache directory of the application to use to store retrieved media and thumbnails.
    
    Parameters:
    
    context - A context.
    
    cacheName - The name of the subdirectory in which to store the cache.
    
    See Also:
    
    getPhotoCacheDir(android.content.Context)
  - get
```
public static Glide get(Context context)
```
    Get the singleton.
    
    Returns:
    
    the singleton
  - init
```
public static void init(Glide glide)
```
  - tearDown
```
public static void tearDown()
```
  - getBitmapPool
```
public BitmapPool getBitmapPool()
```
    Returns the BitmapPool used to temporarily store Bitmaps so they can be reused to avoid garbage collections.
    Note - Using this pool directly can lead to undefined behavior and strange drawing errors. Any Bitmap added to the pool must not be currently in use in any other part of the application. Any Bitmap added to the pool must be removed from the pool before it is added a second time.
    
    Note - To make effective use of the pool, any Bitmap removed from the pool must eventually be re-added. Otherwise the pool will eventually empty and will not serve any useful purpose.
    
    The primary reason this object is exposed is for use in custom ResourceDecoders and Transformations. Use outside of these classes is not generally recommended.
  - getArrayPool
```
public ArrayPool getArrayPool()
```
  - getContext
```
public Context getContext()
```
    Returns:
    
    The context associated with this instance.
  - preFillBitmapPool
```
public void preFillBitmapPool(PreFillType.Builder... bitmapAttributeBuilders)
```
    Pre-fills the BitmapPool using the given sizes.
    Enough Bitmaps are added to completely fill the pool, so most or all of the Bitmaps currently in the pool will be evicted. Bitmaps are allocated according to the weights of the given sizes, where each size gets (weight / prefillWeightSum) percent of the pool to fill.
    
    Note - Pre-filling is done asynchronously using and MessageQueue.IdleHandler. Any currently running pre-fill will be cancelled and replaced by a call to this method.
    
    This method should be used with caution, overly aggressive pre-filling is substantially worse than not pre-filling at all. Pre-filling should only be started in onCreate to avoid constantly clearing and re-filling the BitmapPool. Rotation should be carefully considered as well. It may be worth calling this method only when no saved instance state exists so that pre-filling only happens when the Activity is first created, rather than on every rotation.
    
    Parameters:
    
    bitmapAttributeBuilders - The list of Builders representing individual sizes and configurations of Bitmaps to be pre-filled.
  - clearMemory
```
public void clearMemory()
```
    Clears as much memory as possible.
    
    See Also:
    
    ComponentCallbacks.onLowMemory(), ComponentCallbacks.onLowMemory()
  - trimMemory
```
public void trimMemory(int level)
```
    Clears some memory with the exact amount depending on the given level.
    
    See Also:
    
    ComponentCallbacks2.onTrimMemory(int)
  - clearDiskCache
```
public void clearDiskCache()
```
    Clears disk cache.
    This method should always be called on a background thread, since it is a blocking call.
  - getRequestManagerRetriever
```
public RequestManagerRetriever getRequestManagerRetriever()
```
    Internal method.
  - setMemoryCategory
```
public MemoryCategory setMemoryCategory(MemoryCategory memoryCategory)
```
    Adjusts Glide's current and maximum memory usage based on the given MemoryCategory.
    The default MemoryCategory is MemoryCategory.NORMAL. MemoryCategory.HIGH increases Glide's maximum memory usage by up to 50% and MemoryCategory.LOW decreases Glide's maximum memory usage by 50%. This method should be used to temporarily increase or decrease memory usage for a single Activity or part of the app. Use GlideBuilder.setMemoryCache(MemoryCache) to put a permanent memory size if you want to change the default.
    
    Returns:
    
    the previous MemoryCategory used by Glide.
  - with
```
public static RequestManager with(Context context)
```
    Begin a load with Glide by passing in a context.
    Any requests started using a context will only have the application level options applied and will not be started or stopped based on lifecycle events. In general, loads should be started at the level the result will be used in. If the resource will be used in a view in a child fragment, the load should be started with with(android.app.Fragment)} using that child fragment. Similarly, if the resource will be used in a view in the parent fragment, the load should be started with with(android.app.Fragment) using the parent fragment. In the same vein, if the resource will be used in a view in an activity, the load should be started with with(android.app.Activity)}.
    
    This method is appropriate for resources that will be used outside of the normal fragment or activity lifecycle (For example in services, or for notification thumbnails).
    
    Parameters:
    
    context - Any context, will not be retained.
    
    Returns:
    
    A RequestManager for the top level application that can be used to start a load.
    
    See Also:
    
    with(android.app.Activity), with(android.app.Fragment), with(android.support.v4.app.Fragment), with(android.support.v4.app.FragmentActivity)
  - with
```
public static RequestManager with(Activity activity)
```
    Begin a load with Glide that will be tied to the given Activity's lifecycle and that uses the given Activity's default options.
    
    Parameters:
    
    activity - The activity to use.
    
    Returns:
    
    A RequestManager for the given activity that can be used to start a load.
  - with
```
public static RequestManager with(FragmentActivity activity)
```
    Begin a load with Glide that will tied to the give FragmentActivity's lifecycle and that uses the given FragmentActivity's default options.
    
    Parameters:
    
    activity - The activity to use.
    
    Returns:
    
    A RequestManager for the given FragmentActivity that can be used to start a load.
  - with
```
public static RequestManager with(Fragment fragment)
```
    Begin a load with Glide that will be tied to the given Fragment's lifecycle and that uses the given Fragment's default options.
    
    Parameters:
    
    fragment - The fragment to use.
    
    Returns:
    
    A RequestManager for the given Fragment that can be used to start a load.
  - with
```
public static RequestManager with(Fragment fragment)
```
    Begin a load with Glide that will be tied to the given Fragment's lifecycle and that uses the given Fragment's default options.
    
    Parameters:
    
    fragment - The fragment to use.
    
    Returns:
    
    A RequestManager for the given Fragment that can be used to start a load.
  - with
```
public static RequestManager with(View view)
```
    Begin a load with Glide that will be tied to the lifecycle of the Fragment, Fragment, or Activity that contains the View.
    A Fragment or Fragment is assumed to contain a View if the View is a child of the View returned by the Fragment.getView()} method.
    This method will not work if the View is not attached. Prefer the Activity and Fragment variants unless you're loading in a View subclass.
    This method may be inefficient for large hierarchies. Consider memoizing the result after the View is attached.
    When used in Applications that use the non-support Fragment classes, calling this method will produce noisy logs from FragmentManager. Consider avoiding entirely or using the Fragments from the support library instead.
    
    Parameters:
    
    view - The view to search for a containing Fragment or Activity from.
    
    Returns:
    
    A RequestManager that can be used to start a load.
