glide-helper

This library solve some problems I encountered when using Glide

1. Application crashes caused by reuse Bitmap

An error is reported when using Glide to load pictures on some machines：

Fatal signal 11 (SIGSEGV) at 0x0000000f (code=1), thread 12975 (glide-source-th)

We can use NoDirtyBitmapPool to replace LruBitmapPool

@GlideModule
public class XXX extends AppGlideModule {

   @Override
   public void applyOptions(@NonNull Context context, @NonNull GlideBuilder builder) {
           builder.setBitmapPool(new NoDirtyBitmapPool(new MemorySizeCalculator.Builder(context).build().getBitmapPoolSize()));
   
   }

}

2.Load pictures in APK

configuration：

@GlideModule
public class XXX extends AppGlideModule {

   @Override
   public void registerComponents(@NonNull Context context, @NonNull Glide glide, @NonNull Registry registry) {
       registry.append(ApkResourceDrawable.class, Drawable.class, new ApkResourceLoader.Factory());
   }
}

load pictures in APK：

ApkResourceDrawable model = new ApkResourceDrawable(context
                   , apkPath.getAbsolutePath()
                   , "yourDrawableName"
                   , "defType"
                   , "yourPackageName"
                   )

Glide.with(imageView).load(model).into(imageView);

3. Image file md5 digest

Image HTTP URL with md5 parameter,the md5 parameter value represents the md5 digest value of the image file returned by the server,like this：

https://192.168.0.101:5555/hello.jpg?md5=25f9e794323b453885f5181f1b624d0b

when loading a image, it is necessary to perform md5 digest on the obtained file and compare it with md5 parameter value. The image can be displayed only if they are the same.

configuration：

@GlideModule
public class XXX extends AppGlideModule {

   @Override
   public void registerComponents(@NonNull Context context, @NonNull Glide glide, @NonNull Registry registry) {
       registry.append(MD5CheckUrl.class, InputStream.class, new HttpMD5CheckUrlLoader.Factory());
   }

   @Override
   public boolean isManifestParsingEnabled() {
       return false;
   }

   @Override
   public void applyOptions(@NonNull Context context, @NonNull GlideBuilder builder) {
       builder.setDiskCache(new MD5DiskLruCacheFactory(context));

   }

}

use：

Glide.with(imageView)
        .load(new MD5CheckUrl.Builder("yourImageUrl", "MD5ParameterName").build())
        .apply(new MD5CheckRequestOption().diskCacheStrategy(DiskCacheStrategy.DATA))
        .into(imageView);

the md5 value of the original image loaded from the network and disk will be compared with the md5 parameter value of the image HTTP URL

ProGuard

-keep class com.bumptech.glide.load.engine.DataCacheKey{ *;}

glide-helper

这个库帮助解决了与Glide相关的一些问题

1. Bitmap复用导致的应用闪退

当在某些机器上使用Glide加载图片时报错：
Fatal signal 11 (SIGSEGV) at 0x0000000f (code=1), thread 12975 (glide-source-th) 可以使用NoDirtyBitmapPool替换LruBitmapPool

@GlideModule
public class XXX extends AppGlideModule {

   @Override
   public void applyOptions(@NonNull Context context, @NonNull GlideBuilder builder) {
           builder.setBitmapPool(new NoDirtyBitmapPool(new MemorySizeCalculator.Builder(context).build().getBitmapPoolSize()));
   
   }

}

2.加载APK中的图片

配置：

@GlideModule
public class XXX extends AppGlideModule {

   @Override
   public void registerComponents(@NonNull Context context, @NonNull Glide glide, @NonNull Registry registry) {
       registry.append(ApkResourceDrawable.class, Drawable.class, new ApkResourceLoader.Factory());
   }
}

加载APK中的图片：

ApkResourceDrawable model = new ApkResourceDrawable(context
                   , apkPath.getAbsolutePath()//apk所在路径
                   , "yourDrawableName"//drawable的名字
                   , "defType"//defType类型
                   , "yourPackageName"//APK的包名
                   )

Glide.with(imageView).load(model).into(imageView);

3. 图片文件 MD5 checksum

图片链接中带有MD5 ParameterName-Value,MD5 ParameterValue表示服务器返回的图片文件的MD5值,像这样：

https://192.168.0.101:5555/hello.jpg?md5=25f9e794323b453885f5181f1b624d0b

加载图片时需要对得到的文件进行md5数据摘要，并与MD5 ParameterValue进行比较，相同才能显示图片.

配置：

@GlideModule
public class XXX extends AppGlideModule {

   @Override
   public void registerComponents(@NonNull Context context, @NonNull Glide glide, @NonNull Registry registry) {
       registry.append(MD5CheckUrl.class, InputStream.class, new HttpMD5CheckUrlLoader.Factory());
   }

   @Override
   public boolean isManifestParsingEnabled() {
       return false;
   }

   @Override
   public void applyOptions(@NonNull Context context, @NonNull GlideBuilder builder) {
       builder.setDiskCache(new MD5DiskLruCacheFactory(context));

   }

}

使用：

Glide.with(imageView)
        .load(new MD5CheckUrl.Builder("yourImageUrl", "MD5ParameterName").build())
        .apply(new MD5CheckRequestOption().diskCacheStrategy(DiskCacheStrategy.DATA))
        .into(imageView);

会对从网络、磁盘加载的原始图片与HTTP连接带的MD5值进行MD5比对

ProGuard

#使用图片MD5比对时添加
-keep class com.bumptech.glide.load.engine.DataCacheKey{ *;}
