I am creating an application in which I have a "Game" object which holds some information about the game. Here is my code
Game.java
import android.os.Parcel;
import android.os.Parcelable;
import android.util.Log;
import java.util.Arrays;
/**
* Created by velin on 12/12/2015.
*/
public class Game implements Parcelable {
public GameConfiguration config;
private GameLevel[] levels;
private int currentLevel;
// Constructors
private Game(Parcel in) {
currentLevel = in.readInt();
config = in.readParcelable(GameConfiguration.class.getClassLoader());
// config = GameConfiguration.CREATOR.createFromParcel(in);
levels = in.createTypedArray(GameLevel.CREATOR);
// Log.d(TAG, "Game created from Parcel" + this.toString());
}
public Game(GameConfiguration config) {
this.config = config;
this.currentLevel = 0;
this.levels = new GameLevel[config.levelsConfig.length];
for (GameLevelConfiguration levelConfiguration : config.levelsConfig) {
GameLevel level = new GameLevel(levelConfiguration);
levels[levelConfiguration.levelId] = level;
}
// Log.d(TAG, "Game created" + this.toString());
}
/* Code for Parcelable*/
@Override
public int describeContents() {
return 0;
}
@Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeInt(currentLevel);
dest.writeParcelable(config, 0);
dest.writeTypedArray(levels,0);
}
public static final Parcelable.Creator<Game> CREATOR = new Parcelable.Creator<Game>() {
@Override
public Game createFromParcel(Parcel source) {
return new Game(source);
}
@Override
public Game[] newArray(int size) {
return new Game[size];
}
};
@Override
public String toString() {
return "Game{" +
"config=" + config +
", currentLevel=" + currentLevel +
", levelsConfig" + levels +
'}';
}
public GameLevel[] getLevels() {
return levels;
}
}
GameLevel.java
import android.os.Parcel;
import android.os.Parcelable;
import android.util.Log;
import .main.MainActivity;
/**
* Created by vbk20 on 25/10/2015.
*/
public class GameLevel implements Parcelable {
private final GameLevelConfiguration config;
private final int levelId;
public GameLevel(GameLevelConfiguration config) {
this.config = config;
this.levelId = config.levelId;
// Log.d(MainActivity.TAG, "GameLevel created" + this.toString());
}
private GameLevel(Parcel source) {
levelId = source.readInt();
config = source.readParcelable(GameLevelConfiguration.class.getClassLoader());
// config = GameLevelConfiguration.CREATOR.createFromParcel(source);
// Log.d(MainActivity.TAG, "GameLevel created from Parcel" + this.toString());
}
public int getLevelId(){
return levelId;
}
@Override
public String toString() {
return "GameLevel{" +
"levelId=" + levelId +
", config=" + config +
'}';
}
/* --------- PARCELABLE code --------- */
@Override
public int describeContents() {
return 0;
}
@Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeInt(levelId);
dest.writeParcelable(config, 0);
}
public static final Parcelable.Creator<GameLevel> CREATOR = new Parcelable.Creator<GameLevel>() {
@Override
public GameLevel createFromParcel(Parcel source) {
GameLevel level = new GameLevel(source);
System.out.println("GameLevel createFromParcel -> " + level.levelId);
return level;
}
@Override
public GameLevel[] newArray(int size) {
System.out.println("GameLevel newArray.size = " + size);
return new GameLevel[size];
}
};
}
Then in my 1st Activity (A) I create a Game:
GameLevelConfiguration configLVL1 = new GameLevelConfiguration(0,10,0);
GameLevelConfiguration configLVL2 = new GameLevelConfiguration(0,20,1);
GameLevelConfiguration[] levelConfigs = new GameLevelConfiguration[]{configLVL1};
GameConfiguration gameConfig = new GameConfiguration(0,0,0,0,0,2,Utils.PHOBIAS[phobia],levelConfigs);
Game game = new Game(gameConfig);
System.out.println("ChoosePhobia game.levels.length=" + game.getLevels().length);
for(GameLevel level:game.getLevels()){
System.out.println(level.getLevelId() + "->" +level.toString());
}
Intent i = new Intent(A.this, MainActivity.class);
i.putExtra(Utils.EX_GAME,game);
startActivity(i);
And then I try to get it
System.out.println("MainActivity Extracting Game");
game = getIntent().getExtras().getParcelable(Utils.EX_GAME);
System.out.println("MainActivity game.gameConfig ->" + game.config);
System.out.println("MainActivity game.gameLevels.size" + game.getLevels().length);
for(GameLevel level:game.getLevels()){
System.out.println(level.getLevelId() + "->" +level.toString());
}
For some reason the output from the System.out in activity A is correct and shows that my game creation works:
I/System.out: GameConfiguration!
I/System.out: GameConfiguration{mapImage=0, characterTopImage=0, characterBottomImage=0, characterLeftImage=0, characterRightImage=0, maxLevel=2, phobia='Spider', levelsConfig=[GameLevelConfiguration{image=0, duration=10.0, levelId=0}]}
I/System.out: ChoosePhobia game.levels.length=1
I/System.out: 0->GameLevel{levelId=0, config=GameLevelConfiguration{image=0, duration=10.0, levelId=0}}
but in my mainActivity I get:
I/System.out: MainActivity Extracting Game
I/System.out: GameConfiguration fromParcel!
I/System.out: GameConfiguration{mapImage=0, characterTopImage=0, characterBottomImage=0, characterLeftImage=0, characterRightImage=0, maxLevel=2, phobia='Spider', levelsConfig=[GameLevelConfiguration{image=6619243, duration=1.9582157442846833E-306, levelId=7733294}]}
I/System.out: GameConfiguration createFromParcel gameConfiguration.phobia = Spider
I/System.out: GameLevel newArray.size = 7077989
I/System.out: GameLevel createFromParcel -> 6684718
I/System.out: GameLevel createFromParcel -> 6357096
I/System.out: GameLevel createFromParcel -> 3014770
I/System.out: GameLevel createFromParcel -> 4653102
I/System.out: GameLevel createFromParcel -> 7733349
I/System.out: GameLevel createFromParcel -> 6684782
I/System.out: GameLevel createFromParcel -> 7602273

As you can see it finds objects with very strange IDs and at some point runs out of memory. Any ideas what is going on ?
Thank you
