Question

我已经花了几天时间讨论过这个问题，但仍然无法理解它，也没有谷歌以某种方式与问题相关。

在我的游戏中，我有int[8][8]数组 - gameFieldArray。为了在屏幕旋转或接听电话等期间保存游戏状态，我使用它将其放入onSaveInstanceState(Bundle outState)

中的Bundle

outState.putSerializable(SC.SAVE_GAME_FIELD, gl.getGameField());

然后在onCreate我检索了数组：

gameFieldArray = (int[][])savedInstanceState.getSerializable(SC.SAVE_GAME_FIELD);

一切正常，直到我开始发布签名的apk并将它们发送给朋友进行一些预发布测试。签名的apk由proGuard处理，具有以下设置：

-dontusemixedcaseclassnames
-dontskipnonpubliclibraryclasses
-dontwarn android.support.**
-verbose

-dontoptimize
-dontpreverify

-keepattributes *Annotation*, SourceFile, LineNumberTable, Signature
-keep public class * extends android.app.Activity
-keep public class * extends android.app.Application
-keep public class * extends android.app.Service
-keep public class * extends android.content.BroadcastReceiver
-keep public class * extends android.content.ContentProvider
-keep public class com.google.vending.licensing.ILicensingService
-keep public class com.android.vending.licensing.ILicensingService
-keep public class * extends android.support.v4.app.Fragment
-keep public class * extends android.app.Fragment

-keepclasseswithmembernames class * {
    native <methods>;
}

-keepclasseswithmembernames class * {
    public <init>(android.content.Context, android.util.AttributeSet);
}

-keepclasseswithmembernames class * {
    public <init>(android.content.Context, android.util.AttributeSet, int);
}

 -keepclassmembers public class * extends android.view.View {
  void set*(***);
  *** get*();
 }

-keepclassmembers enum * {
    public static **[] values();
    public static ** valueOf(java.lang.String);
}

-keep class * implements android.os.Parcelable {
  public static final android.os.Parcelable$Creator *;
}

-keepclassmembers class **.R$* {
  public static <fields>;
}

#ACRA-specific:
-keep class org.acra.ACRA {
    *;
}

-keep class org.acra.ReportingInteractionMode {
    *;
}

-keepnames class org.acra.sender.HttpSender$** {
    *;
}

-keepnames class org.acra.ReportField {
    *;
}

-keep public class org.acra.ErrorReporter
{
    public void addCustomData(java.lang.String,java.lang.String);
    public void putCustomData(java.lang.String,java.lang.String);
    public void removeCustomData(java.lang.String);
}

-keep public class org.acra.ErrorReporter
{
    public void handleSilentException(java.lang.Throwable);
}

现在有关重现的步骤：只有我的一个朋友才能重现这一点。我认为那是因为他拥有载有512 MB的Galaxy 9001。当他上场时：

    1) he recieves call
    2) talks, hangs up
    3) game crashes

这是我从ACRA获得的：

没有其他手机（内存量较大）或模拟器转载此内容。这只是当apk与proguard，没有它一切正常。这只是在接听电话时。在游戏中只切换方向时 - 执行相同的代码但不会发生崩溃。

有人有任何线索吗？任何帮助调查这一点将不胜感激！

稍后添加： java.lang.ClassCastException: java.lang.Object[] cannot be cast to int[][] at com.game.maxstr8.f.<init>(GameLogic.java:36)实际上是

gameFieldArray = (int[][])savedInstanceState.getSerializable(SC.SAVE_GAME_FIELD);

- 从保存的Bundle中检索int [] []数组。

在proGuard之后从Bundle获取int [] []时出现ClassCastException
