frescao设置存储路径和大小

public class MyApp extends Application {
    @Override
    public void onCreate() {
        super.onCreate();
        DiskCacheConfig diskCacheConfig =  DiskCacheConfig.newBuilder(this)
                .setBaseDirectoryName("image")
                //缓存大小
                .setMaxCacheSize(10*1024*1024)
                .setBaseDirectoryPath(Environment.getExternalStorageDirectory())
                .build();
        ImagePipelineConfig config = ImagePipelineConfig.newBuilder(this)
                .setMainDiskCacheConfig(diskCacheConfig)
                .build();

        Fresco.initialize(this,config);
    }
}
