Android Parcelable readStringArray（）java.lang.RuntimeException：Nougat上的数组长度不佳

所以我正在处理的应用程序遇到问题，应用程序在Android 7及更高版本上崩溃仅。从logcat中，这个错误似乎发生在我的parcelable类上。Android Parcelable readStringArray（）java.lang.RuntimeException：Nougat上的数组长度不佳

这里就是崩溃发生（具有parcelable类）点：

public class LookupCriteriaBean implements Parcelable, Serializable { 
private String lookupCode; 
private String lookupField; 
private String lookupDisplayName; 
private String lookupSearchValue; 

public LookupCriteriaBean(){   
} 

public LookupCriteriaBean(String s) { 
    if (s == null || "".equals(s.trim())) 
throw new IllegalArgumentException("Invalid lookup criteria setting from server!"); 

    int idx = 0; 
    String[] arrS = Tool.split(s, Global.DELIMETER_DATA); 
    lookupCode = arrS[idx++]; 
    lookupField = arrS[idx++]; 
    lookupDisplayName = arrS[idx++]; 
} 

public LookupCriteriaBean(Parcel in) { 
    String[] arrS = new String[LookupCriteriaBean.class.getFields().length]; 
    in.readStringArray(arrS); 

    int idx = 0; 
    lookupCode = arrS[idx++]; 
    lookupField = arrS[idx++]; 
    lookupDisplayName = arrS[idx++]; 
} 

public String getLookupCode() { 
    return lookupCode; 
} 

public void setLookupCode(String lookupCode) { 
    this.lookupCode = lookupCode; 
} 

public String getLookupField() { 
    return lookupField; 
} 

public void setLookupField(String lookupField) { 
    this.lookupField = lookupField; 
} 

public String getLookupDisplayName() { 
    return lookupDisplayName; 
} 

public void setLookupDisplayName(String lookupDisplayName) { 
    this.lookupDisplayName = lookupDisplayName; 
} 

public String toString() { 
    return lookupDisplayName; 
} 

public int describeContents() { 
    return 0; 
} 

public void writeToParcel(Parcel dest, int flags) { 
    dest.writeStringArray(new String[] { lookupCode, lookupField, lookupDisplayName }); 
} 

public static final Parcelable.Creator<LookupCriteriaBean> CREATOR = new Parcelable.Creator<LookupCriteriaBean>() { 

    public LookupCriteriaBean createFromParcel(Parcel source) { 
     return new LookupCriteriaBean(source); 
    } 

    public LookupCriteriaBean[] newArray(int size) { 
     return new LookupCriteriaBean[size]; 
    } 
}; 

public String getLookupSearchValue() { 
    return lookupSearchValue; 
} 

public void setLookupSearchValue(String lookupSearchValue) { 
    this.lookupSearchValue = lookupSearchValue; 
    } 
}

触发崩溃的线是in.readStringArray(arrS);

问题是崩溃只发生在Android上7和以上，它不会发生在我测试的任何其他设备上，我不知道是什么导致这种情况，因为应用程序运行良好，除了nougat设备以外的其他任何设备。

这里是logcat的输出：

按钮有R按钮.id.search_button按下时在android 7上崩溃崩溃

嗯。 ..所以我尝试了各种各样的事情，甚至重写代码，这个问题仍然存在，它可能是牛轧糖造成的这个，任何想法的东西？

添加logtags你包裹前阵。检查它的长度，然后它被包裹 – Zoe

看看[this]（http://stackoverflow.com/questions/20829975/android-parcelable-bad-array-lengths） - 它是相同的问题，但如果您的问题仅在7.0以上触发，则可能有其他内容。但看看订单并添加调试标签！ – Zoe

['writeStringArray（new String [] {lookupCode，lookupField，lookupDisplayName}）'数组的长度应该是3 ....并且您正在使用'LookupCriteriaBean.class.getFields（）。length'，它是4]（https：//github上。com/android/platform_frameworks_base/blob/master/core/java/android/os/Parcel.java＃L1124） – Selvin

小提示！

您可以使用以下库来简化parcelable的使用。

https://github.com/codepath/android_guides/wiki/Using-Parceler

如果选中www.parcelabler.com，这可能是一个解决办法

public class LookupCriteriaBean implements Parcelable, Serializable { 
private String lookupCode; 
private String lookupField; 
private String lookupDisplayName; 
private String lookupSearchValue; 

public String getLookupSearchValue() { 
    return lookupSearchValue; 
} 

public void setLookupSearchValue(String lookupSearchValue) { 
    this.lookupSearchValue = lookupSearchValue; 
    } 

public String getLookupCode() { 
    return lookupCode; 
} 

public void setLookupCode(String lookupCode) { 
    this.lookupCode = lookupCode; 
} 

public String getLookupField() { 
    return lookupField; 
} 

public void setLookupField(String lookupField) { 
    this.lookupField = lookupField; 
} 

public String getLookupDisplayName() { 
    return lookupDisplayName; 
} 

public void setLookupDisplayName(String lookupDisplayName) { 
    this.lookupDisplayName = lookupDisplayName; 
} 

public String toString() { 
    return lookupDisplayName; 
} 

// 
// Here is the implementation of parcelable 
// 
    protected LookupCriteriaBean(Parcel in) { 
     lookupCode = in.readString(); 
     lookupField = in.readString(); 
     lookupDisplayName = in.readString(); 
     lookupSearchValue = in.readString(); 
    } 

    @Override 
    public int describeContents() { 
     return 0; 
    } 

    @Override 
    public void writeToParcel(Parcel dest, int flags) { 
     dest.writeString(lookupCode); 
     dest.writeString(lookupField); 
     dest.writeString(lookupDisplayName); 
     dest.writeString(lookupSearchValue); 
    } 

    @SuppressWarnings("unused") 
    public static final Parcelable.Creator<LookupCriteriaBean> CREATOR = new Parcelable.Creator<LookupCriteriaBean>() { 
     @Override 
     public LookupCriteriaBean createFromParcel(Parcel in) { 
      return new LookupCriteriaBean(in); 
     } 

     @Override 
     public LookupCriteriaBean[] newArray(int size) { 
      return new LookupCriteriaBean[size]; 
     } 
    }; 
}

注意：YOu不能声明两个具有相同名称的对象的实现，除非你添加它所嵌套的包/类（取决于它是否是独立类） – Zoe

重写我的代码几次广告引用同样的问题其他的答案，拆分后阵字符串我用来分开字符串修复这个问题，虽然我仍然不知道为什么getStringArray(arrS)只会崩溃在Android 7及以上。

我很想知道为什么我的代码仍然运行在较低的版本，但罚款。

所以两个分开的所有领域和访问它们在正确的顺序，然后它的工作。

这里是我的固定码：

---------------snip--------------------------------- 

public LookupCriteriaBean(Parcel in) { 
    lookupCode = in.readString(); 
    lookupField = in.readString(); 
    lookupDisplayName = in.readString(); 
    } 

public void writeToParcel(Parcel dest, int flags) { 
    dest.writeString(lookupCode); 
    dest.writeString(lookupField); 
    dest.writeString(lookupDisplayName); 
}
