文章讲述了在使用华为HMSAds时，开发者遇到SplashView加载错误的情况，错误原因为ClassNotFoundException，提示可能是因为未正确处理资源混淆。解决方法是确保在Java包中创建的activity中正确导入并处理华为广告的相关资源。
华为广告打包时报错
fata日志不一样能反映出完整的错误日志信息，仅看fata日志具有误导性，有可能指向错误的方向。
通过看完整的日志可见，错误的原因为
Caused by: java.lang.ClassNotFoundException: com.huawei.hms.ads.base.R$dimen

收不到回调问题研究
添加华为闪屏页后，我们在java包中创建了一个activity，创建的此activity中的内容，没有进行防混淆。
导致华为this.splashView.load时传入的第var5参数异常。与逆向导入资源的名称不一致。程序虽然没有报错，但是一直收不到相关回调。
SplashView.SplashAdLoadListener var5;
var5 = new SplashView.SplashAdLoadListener() {
public void onAdLoaded() {
String[] var1;
(var1 = new String[1])[0] = "onAdLoaded";
LogUtils.logI("TK_HuaWeiSplashActivity", var1);
}
public void onAdFailedToLoad(int var1) {
String[] var2;
(var2 = new String[1])[0] = "onAdFailedToLoad";
LogUtils.logI("TK_HuaWeiSplashActivity", var2);
}
public void onAdDismissed() {
String[] var1;
(var1 = new String[1])[0] = "onAdDismissed";
LogUtils.logI("TK_HuaWeiSplashActivity", var1);
}
}.<init>();
String[] var3;
(var3 = new String[1])[0] = "splashAdLoadListener:" + <undefinedtype>.class;
LogUtils.logI("TK_HuaWeiSplashActivity", var3);
this.splashView.load(splash_ad_id, this.splash_game_orientation, var1, var5);
