Glide加载图片出现java.lang.IllegalStateException: Can't call reconfigure() on a recycled bitmap

Glide简介

Glide是面向Android的快速高效的开源媒体管理和图像加载框架，提供媒体解码，内存和磁盘缓存以及资源池等简单易用的用户体验。

Glide用法

gradle依赖

repositories {  mavenCentral() // jcenter() works as well because it pulls from Maven Central}dependencies {  compile 'com.github.bumptech.glide:glide:3.7.0'  compile 'com.android.support:support-v4:19.1.0'}

代码片段

// For a simple view:@Override public void onCreate(Bundle savedInstanceState) {  ...  ImageView imageView = (ImageView) findViewById(R.id.my_image_view);  Glide.with(this).load("http://goo.gl/gEgYUd").into(imageView);}// For a simple image list:@Override public View getView(int position, View recycled, ViewGroup container) {  final ImageView myImageView;  if (recycled == null) {    myImageView = (ImageView) inflater.inflate(R.layout.my_image_view, container, false);  } else {    myImageView = (ImageView) recycled;  }  String url = myUrls.get(position);  Glide    .with(myFragment)    .load(url)    .centerCrop()    .placeholder(R.drawable.loading_spinner)    .crossFade()    .into(myImageView);  return myImageView;}

ProGuard混淆规则

-keep public class * implements com.bumptech.glide.module.GlideModule-keep public enum com.bumptech.glide.load.resource.bitmap.ImageHeaderParser$** {  **[] $VALUES;  public *;}# for DexGuard only-keepresourcexmlelements manifest/application/meta-data@value=GlideModule

兼容性

Glide详细的兼容性问题可查看Github仓库，这里只列举一个：
- 圆角图片
CircleImageView/CircularImageView/RoundedImageView 与TransitionDrawable (.crossFade() 配合 .thumbnail() 或 .placeholder()使用时) 和 animated GIFs配合使用时会出现已知的问题，解决方法是使用BitmapTransformation (.circleCrop() 在v4版本才支持) 或者 .dontAnimate()。

Can’t call reconfigure() on a recycled bitmap

问题原因

This error usually means that the bitmap pool is tainted, so if you’re using Transformations anywhere in the app, that could be a culprit. Someone is recycling Bitmaps that are in the pool, outside of Glide’s knowledge.

Transformations anywhere in the app could be a culprit.
App中任何地方出现的Transformations可能就是罪魁祸首，Transformation就是配合Glide实现圆角图片的API。

典型代码

public class BitmapFixedWidthTransform extends BitmapTransformation {    public BitmapFixedWidthTransform(Context context) {        super(context);    }    @Override    protected Bitmap transform(BitmapPool pool, Bitmap toTransform, int outWidth, int outHeight) {        int targetWidth = outWidth;        double aspectRatio = (double) toTransform.getHeight() / (double) toTransform.getWidth();        int targetHeight = (int) (targetWidth * aspectRatio);        Bitmap result = Bitmap.createScaledBitmap(toTransform, targetWidth, targetHeight, true);        if (result != toTransform) {            // Same bitmap is returned if sizes are the same            toTransform.recycle(); // removed this        }        return result;    }    @Override    public String getId() {        return "transformation" + " desiredWidth";    }}

解决方法

解决方法其实已经在上面的代码注释中，既然是由recycled bitmap引起的，那么去掉下面的代码就OK：

toTransform.recycle(); // removed this
