java - Android Studio 中的 IllegalAccessException 目标 android 为 4.4

Question

在我的 Android 项目中，我最初的目标是 Android 6，并且一切都运行正常。

现在我在 Android 4.4 设备(真实设备和 AVD)上运行它，它因 IllegalAccessException 崩溃。

这就是崩溃的地方

    this.PractitionerList.add(new
            PractitionerItem(1, "01A1234E", "Mary", "1st", "London", "Y")

    );

PractitionerItem是一个公共(public)类，PractitionerList是一个像这样声明的数组列表

this.PractitionerList = new ArrayList();

这是日志猫......

.....以及调用它的类中的这个(主要部分)...

Public class SearchTheRegister extends AppCompatActivity {

 //// THIS LINE IS WHERE IT FAILS /////////////// 
    this.PractitionerList.add(new
            PractitionerItem(1, "01A1234E", "Mary", "1st", "London", "Y")

    );

有什么想法吗？

Answer 1

我不确定这是否能解决您的问题，但我有类似的问题，并且我意识到我的可包裹实现是错误的。我在下面为您重新生成了一个可打包的实现:

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

    @Override
    public void writeToParcel(Parcel dest, int flags) {
        dest.writeValue(this.PRN);
        dest.writeString(this.PIN);
        dest.writeString(this.Fname);
        dest.writeString(this.Lname);
        dest.writeString(this.Town);
        dest.writeString(this.YesNo);
    }

    public PractitionerItem() {
    }

    protected PractitionerItem(Parcel in) {
        this.PRN = (Integer) in.readValue(Integer.class.getClassLoader());
        this.PIN = in.readString();
        this.Fname = in.readString();
        this.Lname = in.readString();
        this.Town = in.readString();
        this.YesNo = in.readString();
    }

    public static final Creator<PractitionerItem> CREATOR = new Creator<PractitionerItem>() {
        @Override
        public PractitionerItem createFromParcel(Parcel source) {
            return new PractitionerItem(source);
        }

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

如果这不起作用，您可以尝试向您的应用添加 MultiDex 支持。关于 Kitkat、ArrayList 和 Parcelable 存在一个奇怪的问题。

添加多重分包支持:

首先更改你的 gradle，如下所示:

android {
    defaultConfig {
        ...
        multiDexEnabled true
        ...
    }
}

dependencies {
  ...
  compile 'com.android.support:multidex:1.0.0'
  ...

}

第二次从 Multidex 应用程序扩展您的应用程序或在 OnCreate 中调用 Multidex.init:

public class YourApplication extends MultiDexApplication
{
    ...
}

或

public class YourApplication extends Application
{
    protected void attachBaseContext(Context base)
    {
        super.attachBaseContext(base);
        MultiDex.install(this);
    }
}

如果这些解决方案不起作用，请告诉我，让我们尝试找出新的解决方案。

祝你好运。
