[android-developers] Re: Remote Interface - Parcelables problem...
Has anyone had experience with passing a pacelable class through an
aidl interface?
Just cant get it to work the way they describe here
http://developer.android.com/guide/developing/tools/aidl.html#implementtheinterface
cheers,

[android-developers] Re: Remote Interface - Parcelables problem...
Yes, I have done plenty of this now. Here's how I do it:
My Parcelable is called an OnlineUser. Here's the important stuff:
private OnlineUser(Parcel in) {
readFromParcel(in);
}
public void writeToParcel(Parcel out, int arg1) {
writeToParcel(out);
}
public void writeToParcel(Parcel out) {
out.writeInt(id);
out.writeString(userName);
out.writeString(dictionary);
out.writeInt(allowRandomGames ? 1 : 0);
}
public void readFromParcel(Parcel in) {
id = in.readInt();
userName = in.readString();
dictionary = in.readString();
allowRandomGames = in.readInt() == 1;
}
public int describeContents() {
return 0;
}
public static final Parcelable.Creator CREATOR = new
Parcelable.Creator() {
public OnlineUser createFromParcel(Parcel in) {
return new OnlineUser(in);
}
public OnlineUser[] newArray(int size) {
return new OnlineUser[size];
}
};

[android-developers] Re: Remote Interface - Parcelables problem...
Thanks, though it doesnt look like you are doing anything different to
i am. When you initialise an instance of your OnlineUser, would you do
it using OnlineUser.CREATOR.createFromParcel(p), after packing your
parcel?
If you can see a problem with my code in my original post, please
advise? The issue is the parcel gets packed with non-zero integers,
but when readFromParcel gets called only 0 integers get read out.
