Parcel Unmarshalling，抛出运行时异常(Parcel Unmarshalling, Runtime Exception is thrown)

 我试图创建一个显示周期表的应用程序然后你可以点击每个元素带你到另一个屏幕看它的摩尔质量。 从那里你可以去另一个屏幕。 问题是每当我点击一个元素，而不是进入下一个屏幕时，我会得到一个运行时异常。 这将打印在堆栈跟踪中。 我如何解决这个问题，我仔细检查了Element类中实现parcelable的所有内容是否正确完成

 万一我错过了什么，这里是实现Parcelable的类 
 

public class Element implements Parcelable {

private double molarMass;
private String name;
private int ID;
private String symbol;

public Element (String elementName,  int a, double mass, String sym){
    name=elementName;
    molarMass=mass;
    ID= a;
    symbol=sym;
}

public Element(Parcel in) {
name=in.readString();
symbol=in.readString();
ID=in.readInt();
molarMass=in.readDouble();
}

public String getName (){

    return name;
}

public double getMass (){
    return molarMass;
}

public int getID (){

    return ID;
}

public String getSymbol (){

    return symbol;
}

public static final Parcelable.Creator<Element> CREATOR
= new Parcelable.Creator<Element>() {
    public Element createFromParcel(Parcel in) {
        return new Element(in);
    }

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

@Override
public int describeContents() {
    // TODO Auto-generated method stub
    return 0;
}

@Override
public void writeToParcel(Parcel dest, int flags) {
      dest.writeString (name);
       dest.writeInt (ID);
       dest.writeDouble (molarMass);
       dest.writeString (symbol);

}

/*public double calculate (double massInGrams){

double as=massInGrams/molarMass;
return as;

 

 } * / 
 

 } 

I tried to make an app that would display the periodic table and then you could click each element to take you to another screen to see its molar mass. From there you can go to another screen. The problem is that whenever I click on an element, instead of going to the next screen I get a runtime exception. This is printed in the stack trace. How do I solve the problem, I double checked that everything in the Element class which implements parcelable was done correctly

Just in case I missed something, here is the class which implements Parcelable 
 

public class Element implements Parcelable {

private double molarMass;
private String name;
private int ID;
private String symbol;

public Element (String elementName,  int a, double mass, String sym){
    name=elementName;
    molarMass=mass;
    ID= a;
    symbol=sym;
}

public Element(Parcel in) {
name=in.readString();
symbol=in.readString();
ID=in.readInt();
molarMass=in.readDouble();
}

public String getName (){

    return name;
}

public double getMass (){
    return molarMass;
}

public int getID (){

    return ID;
}

public String getSymbol (){

    return symbol;
}

public static final Parcelable.Creator<Element> CREATOR
= new Parcelable.Creator<Element>() {
    public Element createFromParcel(Parcel in) {
        return new Element(in);
    }

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

@Override
public int describeContents() {
    // TODO Auto-generated method stub
    return 0;
}

@Override
public void writeToParcel(Parcel dest, int flags) {
      dest.writeString (name);
       dest.writeInt (ID);
       dest.writeDouble (molarMass);
       dest.writeString (symbol);

}

/*public double calculate (double massInGrams){

double as=massInGrams/molarMass;
return as;

 

}*/
 

}

最满意答案

 是的，Android TV支持FCM。 图书馆和实施是一样的。 
 

 但是，由于电视机没有系统栏，因此它与平板电脑的功能不同。 在系统自动在系统栏上显示通知的情况下，它什么都不做。 
 

 在你的特定情况下，它会正常工作，因为你想要总是获得FCM消息，然后在后台处理它。 

Yes, Android TV supports FCM. Libraries and implementation are the same.
 

However, it does not work the same as for phones as tablets, since the TV does not have a system bar. On the cases where the system will automatically display the notification on the system bar, it does nothing.
 

In your particular case, it will work fine, since you want to always get the FCM message and then process it on the background.
