3.自定义一个类继承Application

package com.example.app;

import android.app.Application;
import android.os.Environment;

import com.facebook.cache.disk.DiskCacheConfig;
import com.facebook.drawee.backends.pipeline.Fresco;
import com.facebook.imagepipeline.core.ImagePipelineConfig;

import java.io.File;

public class MyApp extends Application {
    @Override
    public void onCreate() {
        super.onCreate();
        File file = new File(Environment.getExternalStorageDirectory()+File.separator+"frescocache");
        Fresco.initialize(this,ImagePipelineConfig.newBuilder(this).
                    setMainDiskCacheConfig(
                DiskCacheConfig.newBuilder(this)
                        .setBaseDirectoryPath(file)
                        .build()
        ).build());

    }
}

4.清单文件中添加权限

<uses-permission android:name="android.permission.INTERNET"/>
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>

5.需导入的依赖

 compile 'com.facebook.fresco:fresco:1.10.0'
 implementation 'com.facebook.fresco:animated-gif:1.10.0'

效果图如下
