Glide question you cannot start a load for a destroyed activity

Basic use ：
Glide.with(context).load(imageUrl).into(imageView);

appear “You cannot start a load for a destroyed activity” The scene is ：
Like when the third-party server requests pictures , In the process of requesting the network , Shut down the activity, Will report this error .

as a result of ：
The main reason is that context On , Because although it is closed activity, But after the successful callback of the network comes back , Get the picture address , Reuse glide When loading images ,activity It has been finish 了 ~
see glide Source code ：

 

  Then throw an exception here ：

Is that when activity.isDestroyed() When This anomaly will occur ~

There are also several other exceptions ： 
You cannot start a load on a fragment before it is attached

You cannot start a load on a null Context

In the final analysis, it is because we have introduced a destroyed Activity Or an empty one Context ,Fragment Mounted Activity Caused by emptiness

Review the scenarios used , It is called after the successful callback Glide When executed Glide.with(); When the method is used , Current Activity It has been destroyed , That's why this problem .

The solution is ：

In the use of activity When parameters are passed ,

if(!this.isFinishing()) {
        Glide.with(this).....
}

or

if(!this.isDestroyed()) {
        Glide.with(this).....
}

When using context  When parameters are passed ,

​if(context !=null) {
        Glide.with(context).....
}

​

When using fragment When parameters are passed ,

if (fragment != null && fragment.getActivity() != null) {
        Glide.with(fragment).....
}
