StartApp广告错误

Question

错误如下：_

  

java.lang.NullPointerException：尝试在空对象引用上调用虚方法'int java.lang.Enum.ordinal（）'                                                                                   在com.startapp.android.publish.cache.g.i（StartAppSDK：277）                                                                                   在com.startapp.android.publish.cache.g.j（StartAppSDK：374）                                                                                   at com.startapp.android.publish.cache.g $ 1.onFailedToReceiveAd（StartAppSDK：356）                                                                                   在com.startapp.android.publish.cache.i $ 3 $ 1.run（StartAppSDK：241）                                                                                   在android.os.Handler.handleCallback（Handler.java:754）                                                                                   在android.os.Handler.dispatchMessage（Handler.java:95）                                                                                   在android.os.Looper.loop（Looper.java:163）                                                                                   在android.app.ActivityThread.main（ActivityThread.java:6237）                                                                                   at java.lang.reflect.Method.invoke（Native Method）                                                                                   在com.android.internal.os.ZygoteInit $ MethodAndArgsCaller.run（ZygoteInit.java:877）                                                                                   在com.android.internal.os.ZygoteInit.main（ZygoteInit.java:767）

之前它工作正常，但现在出现了这个错误。

onCreate方法我称之为：

// StartAppSDK.init(this, "210075679", true);
setContentView(R.layout.activity_main);
StartAppSDK.init(MainActivity.this, "210075679", true);

Answer 1

我在Progaurd规则中添加了这个答案后得到了我的答案

-keep class com.startapp.** {*;}
-keepattributes Exceptions, InnerClasses, Signature, Deprecated, 
SourceFile,LineNumberTable, *Annotation*, EnclosingMethod
-dontwarn android.webkit.JavascriptInterface
