java - 是否可以通过广播接收器在 Android 应用程序之间传递自定义对象？

Question

假设有 2 个 Android 应用程序，A 和 B，B 希望将 Android 应用程序 A 中定义的自定义对象传递给 A 中定义的广播接收器，后者接受一个额外的并将其转换为自定义对象如下所示。

public void onReceive(Context paramContext, Intent Intent ){
...
paramIntent = (CustomClass)intent.getSerializableExtra("msg_bean");

假设广播接收器被导出，我尝试在 App B 中定义自定义类，以便我可以在 B 中实例化它并像这样将其广播到接收器:

    CustomClass bean = new CustomClass ();
    intent.putExtra("msg_bean", bean);
    sendBroadcast(intent);

假设 App A 有包 a.b.c，B 有包 d.e.f，我收到错误 ClassDef not found:d.e.f.CustomClass not found in App B，因为我发送给接收者的对象是路径 d.e.f.CustomClass 因为它被定义了在 App B 中。但是，在 App A 中定义的相同 CustomClass 具有路径 a.b.c.CustomClass。有什么方法可以手动定义对象 bean 的类路径，使其遵循 App A 中的类路径？(a.b.c.CustomClass)

Yes you can pass you need to create your bean class like this:
import android.os.Parcel;
import android.os.Parcelable;
public class CustomClass implements Parcelable {

    private String name;
    private int thumbNail;

    public CustomClass() {
    }

    public CustomClass(String name, int thumbnail) {
        this.name = name;
        this.thumbNail = thumbnail;
    }

    protected CustomClass(Parcel in) {
        name = in.readString();
        thumbNail = in.readInt();
    }

    @Override
    public void writeToParcel(Parcel dest, int flags) {
        dest.writeString(name);
        dest.writeInt(thumbNail);
    }

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

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

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

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getThumbNail() {
        return thumbNail;
    }

    public void setThumbNail(int thumbNail) {
        this.thumbNail = thumbNail;
    }

}

=> how to call intent in send broadcast:

CustomClass bean = new CustomClass();
intent.putExtra("msg_bean", bean);
sendBroadcast(intent);

=> How to get object in onReceive() method:
public void onReceive(Context paramContext, Intent intent) {
CustomClass bean = intent.getExtras().getParcelable("msg_bean");
}
