App一定要在AndroidManifest.xml中注册!!!

 public class App extends Application {
    @Override
    public void onCreate() {
        super.onCreate();
        //Fresco无缓存
        //Fresco.initialize(this);

        //Fresco缓存
        Fresco.initialize(this,ImagePipelineConfig.newBuilder(App.this)
                .setMainDiskCacheConfig(
                        DiskCacheConfig.newBuilder(this)
                                .setBaseDirectoryName("CacgPic")
                                .setBaseDirectoryPath(Environment.getExternalStoragePublicDirectory("photo"))
                                .build()
                )
                .build());
    }
