Glide升级到4.x版本遇到的问题

 

Failed to find GeneratedAppGlideModule. You should include an annotationProcessor compile dependency on com.github.bumptech.glide:compiler in your application and a @GlideModule annotated AppGlideModule implementation or LibraryGlideModules will be silently ignored.
依赖的glide版本是

    // glide
    implementation ('com.github.bumptech.glide:glide:4.8.0') {
        exclude group: "com.android.support"
    }
    annotationProcessor 'com.github.bumptech.glide:compiler:4.8.0'

查阅官方文档之后发现，4.x版本的Glide在接口调用和4.x之前有很大区别。

在github的issue里，找到如下答案：

To use the generated API in your application, you need to perform two steps:

1.  Add a dependency on Glide’s annotation processor:

    ``` repositories { mavenCentral() } dependencies { annotationProcessor 'com.github.bumptech.glide:compiler:4.8.0' } ``` 2. Include a [`AppGlideModule`] ``` package com.example.myapp; import com.bumptech.glide.annotation.GlideModule; import com.bumptech.glide.module.AppGlideModule; @GlideModule public final class MyAppGlideModule extends AppGlideModule {} ``` You’re not required to implement any of the methods in `AppGlideModule` for the API to be generated. You can leave the class blank as long as it extends `AppGlideModule` and is annotated with `@GlideModule`. 

按照文档，添加AppGlideModule之后，问题解决。

asBitmap() 接口找不到了

查阅文档后发现是4.x的接口变动了

for anyone came here and still have this issue, I found the way to fix it, 
you must add the asBitmap() right After with() and it will work just like old times 

代码做如下修改后解决：

// Put asBitmap() right after Glide.with(context)  for glide 4.x
        Glide.with(mActivity).asBitmap()
                .load(url)
                .listener(new RequestListener<Bitmap>() {
                              @Override
                              public boolean onLoadFailed(@Nullable GlideException e, Object o, Target<Bitmap> target, boolean b) { return false; } @Override public boolean onResourceReady(Bitmap bitmap, Object o, Target<Bitmap> target, DataSource dataSource, boolean b) { Log.d(TAG, "get serialNo : " + serialNo + " cover successful!"); if (mPreviewingFaceMap.containsKey(serialNo)) { mPreviewingFaceMap.get(serialNo).activityCoverBitmap = bitmap; } return false; } } ).submit();
