R8和Proguard规则

本文介绍了R8和Proguard规则的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我在我的android项目中正在使用github/amalChandran/trail-android这个库.动画效果非常好.但是，启用R8后，动画无法正常工作.该库没有任何Proguard建议.我在其中一种方法中添加了以下代码块，

I am using github/amalChandran/trail-android this library in my android project. The animation was working perfectly fine. But, after enabling R8, the animation is not working. The library does not have any Proguard suggestion. I added the following block in one of my method,

googleMap.setOnMapLoadedCallback(() -> { Route normalOverlayPolyline = new Route.Builder(mRouteOverlayView) .setRouteType(RouteType.PATH) .setCameraPosition(mMap.getCameraPosition()) .setProjection(mMap.getProjection()) .setLatLngs(mRoute) .setBottomLayerColor(Color.YELLOW) .setTopLayerColor(Color.RED) .create(); map.setOnCameraMoveListener(() -> mRouteOverlayView.onCameraMove(map.getProjection(), map.getCameraPosition()));

在定义了两个全局变量的地方，

Where I have two global variables defined,

public Route route; public RouteOverlayView mRouteOverlayView;

现在，我在Usage.txt中有一些详细信息

Now, I have some details in my usage.txt

public void onCameramove(com.google.android.gms.maps.GoogleMap,com.obhai.polyline.trail.RouteOverlayView)

有什么办法可以在proguard-rules.pro中编写一些东西，以使R8不会删除此部分吗?

Is there any way to write something in proguard-rules.pro so that R8 doesn't remove this part?

推荐答案

感谢@sgjesse的提示.我终于有了缩小的proguard规则，以保持功能正常运行.

Thanks to @sgjesse for his hint. I finally got my narrowed down proguard rule to keep my feature functioning.

-keep class com.amalbit.trail.AnimationRouteHelper { *;}

添加此规则可达到我的目的.

adding this rule served my purpose.
