JasperReports export to Excel uses only last set background color

Im pretty pretty new to Dynamic-Jasper, but due to work i had to add a new feature to our already implemented solution.
My Problem
The Goal is to add a Column to a report that consists only out of a background-color based on some Information. I managed to do that, but while testing I stumbled upon a Problem. While all my Columns in the html and pdf view had the right color, the Excel one only colored the fields in the last Color.
While debugging i noticed, that the same colored Fields had the same templateId, but while all Views run through mostly the same Code the Excel one showed different behavior and had the same ID in all fields.
My Code where I manipulate the template
for(JRPrintElement elemt : jasperPrint.getPages().get(0).getElements()) {
if(elemt instanceof JRTemplatePrintText) {
JRTemplatePrintText text = (JRTemplatePrintText) elemt;
(...)
if (text.getFullText().startsWith("COLOR_IDENTIFIER")) {
String marker = text.getFullText().substring(text.getFullText().indexOf('#') + 1);
text.setText("ID = " + ((JRTemplatePrintText) elemt).getTemplate().getId());
int rgb = TypeConverter.string2int(Integer.parseInt(marker, 16) + "", 0);
((JRTemplatePrintText) elemt).getTemplate().setBackcolor(new Color(rgb));
}
}
}
The html view
The Excel view
Temporary Conclusion
The same styles uses the same Objects in the background and the JR-Excel export messes something up by assigning the same Object to all the Fields that I manipulated there. If anyone knows of a misstake by me or potential Solutions to change something different to result the same thing please let me know.
Something different I tried earlier, was trying to set the field in an evaluate Method that was called by Jasper. In that method we assign the textvalue of each field. It contained a map with JRFillFields, but unfortunatelly the Map-Implementation denied access to them and just retuned the Value of those. The map was provided by dj and couldn't be switched with a different one.
Edit
We are using JasperReports 6.7.1

I found a Solution, where I replaced each template with a new one that was supposed to look exactly alike. That way every Field has its own ID guaranteed and its not up to chance, how JasperReports handles its Data internaly.
JRTemplateElement custom =
new JRTemplateText(((JRTemplatePrintText) elemt).getTemplate().getOrigin(),
((JRTemplatePrintText) elemt).getTemplate().getDefaultStyleProvider());
custom.setBackcolor(new Color(rgb));
custom.setStyle(((JRTemplatePrintText) elemt).getTemplate().getStyle());
((JRTemplatePrintText) elemt).setTemplate(custom);

How to load a Google maps static map using Picasso?

In my Android app I use Picasso to load images. This normally works perfectly well.
Today I tried loading a static image from the google maps api, but this doesn't seem to work. When I open the example link as provided on their info page, I get to see the static map image perfectly well. When I load it in my Android app using the line below, I get nothing at all.
Picasso.with(getContext()).load("http://maps.googleapis.com/maps/api/staticmap?center=Brooklyn+Bridge,New+York,NY&zoom=13&size=370x250&maptype=roadmap%20&markers=color:blue|label:S|40.702147,-74.015794&markers=color:green|label:G|40.711614,-74.012318%20&markers=color:red|color:red|label:C|40.718217,-73.998284&sensor=false").into(mapView);
I also tried to download the image and uploading it to my personal webspace, from which it loads perfectly well, but somehow, it doesn't seem to load directly from the direct google API url.
Does anybody know why this is so, and how I can solve it?

The only programmatic point-of-failure that comes to mind is in parsing the URI. Looking at the current Picasso code (https://github.com/square/picasso/blob/master/picasso/src/main/java/com/squareup/picasso/Picasso.java) I see the following:
public RequestCreator load(String path) {
if (path == null) {
return new RequestCreator(this, null, 0);
}
if (path.trim().length() == 0) {
throw new IllegalArgumentException("Path must not be empty.");
}
return load(Uri.parse(path));
}
So I'd first debug
Uri.parse("http://maps.googleapis.com/maps/api/staticmap?center=Brooklyn+Bridge,New+York,NY&zoom=13&size=370x250&maptype=roadmap%20&markers=color:blue|label:S|40.702147,-74.015794&markers=color:green|label:G|40.711614,-74.012318%20&markers=color:red|color:red|label:C|40.718217,-73.998284&sensor=false")
and see what that Object looks like. Does it drop or confuse any of your parameters?
If that doesn't lead you anwhere, try downloading the file manually using a HttpClient [or similar]. Then at least you can fully debug the request/response.
Also, I know Google maps has some limits -- are you sure you haven't reached them?

replace http with https
replace | with %7C
add api key

The .loadMap() function has many declared variables. This is the heart of the whole process.
So what is required for the static maps API to give us an image is that we make an http request with a given url, for which an image response (URL) is received. Let us run through the meaning and utility of these variables. Yes, all of them have a completely different meaning!
The mapUrlInitial variable is always the same while making an API call. It has a query of center ( ?center ) which specifies that we want the location to be centered in the map.
The mapUrlProperties variable contains a string where you control the actual zooming of the image response you will get, the size ofthe image and the color of the marker which will point out our place.
The mapUrlMapType variable is a string where you can actually determine the marker size you want and the type of the map. We are using a roadtype map in the app.
Finally latLong is a string which concatenates the latitude and the longitude of the place we want to pinpoint!
We then concatenate all of these strings to form a feasible Url. The Url is then loaded as we have seen above, in the Picasso code. One thing we can notice is that an event object is always required for all of this to happen, because we are able to fetch the position details using the event object! Final Code:-
fun loadMap(event: Event): String{
//location handling
val mapUrlInitial = “https://maps.googleapis.com/maps/api/staticmap?center=”
val mapUrlProperties = “&zoom=12&size=1200×390&markers=color:red%7C”
val mapUrlMapType = “&markers=size:mid&maptype=roadmap”
val latLong: String = “” +event.latitude + “,” + event.longitude
return mapUrlInitial + latLong + mapUrlProperties + latLong + mapUrlMapType
}
//load image
Picasso.get()
.load(loadMap(event))
.placeholder(R.drawable.ic_map_black_24dp)
.into(rootView.image_map)

Android Libgdx TileAtlas

I am trying to add a Map to my libgdx app as a proof of concept. It seems that no matter how I make a packfile, the com.badlogic.gdx.graphics.g2d.tiled.TileAtlas constructor TileAtlas(TiledMap map, FileHandle inputDir) will not correctly read it. My Tile Map is simple and has only 2 tiles, and both the external gui and internal system will generate a packed file.
Here's the issue, either I name the packfile with a filename to match one of my images to satisfy line 2 below, or the method errors out. If I add 2 packfiles, one for each name of an image in my tile set, I find the Atlas isn't constructed correctly in memory. What am I missing here? Should there only ever be one tile in a tilemap?
Code from Libgdx:
for (TileSet set : map.tileSets) {
FileHandle packfile = getRelativeFileHandle(inputDir, removeExtension(set.imageName) + " packfile");
TextureAtlas textureAtlas = new TextureAtlas(packfile, packfile.parent(), false);
Array<AtlasRegion> atlasRegions = textureAtlas.findRegions(removeExtension(removePath(set.imageName)));
for (AtlasRegion reg : atlasRegions) {
regionsMap.put(reg.index + set.firstgid, reg);
if (!textures.contains(reg.getTexture())) {
textures.add(reg.getTexture());
}
}
}

com.badlogic.gdx.graphics.g2d.tiled --> It looks like you're using the old tiled API. I don't even think that package exists anymore, so you should probably download a newer version.
Check out this blog article. I haven't used the new API yet, but at a quick glance it looks much easier to load maps.

Error with Images

I recently finished the basics of a game that I'm making and I was going to send it to some friends, but whenever they open the .jar it's just a grey window. When I heard that I assumed it was because of the way I got the images (I used a full path: C:\Users\etc). I did some Googling and found a way to get images that seemed more efficient.
private static Image[] mobImages = new Image[1];
public static void loadImages()
{
mobImages[1] = Handler.loadImage("res/EnemyLv1.png");
}
public static Image getMobImages(int index)
{
return mobImages[index];
}
That's what I would like to use. But I did that and changed the rest of my code to support that. And whenever I run a game I get a few errors. Which all point back to
this:
if(getBounds().intersects(tempEnemy.getBounds()))
and so probably the way I'm getting the images too. How could I fix this? And are there better ways to get Images? I've tried a few but they haven't worked.
EDIT: I finally solved all of the errors! :D The only problem is that none of the images appear. Here's my code again. Any more help? That would be fantastic! Thanks everybody for the support so far!

Hard to say whats going wrong in your code. However I recommend you put your image files into a package in the java project (so they will be part of the JAR file) and access them using Class.getResource()/Class.getResourceAsStream(). That avoids multiple pitfalls and keeps everything together.
A sample how to structure your images into the packages:
myproject
images
ImageLocator.class
MyImage1.jpg
MyImage2.jpg
The ImageLocator class then needs to use relative pathes (just the image name + extension) to access to resources.
public class ImageLocator {
public final static String IMAGE_NAME1 = "MyImage1.jpg";
public static Image getImage(final String name) {
URL url = ImageLocator.class.getResource(name);
Image image = Toolkit.getDefaultToolkit().createImage(url);
// ensure the image is loaded
return new ImageIcon(image).getImage();
}
}
This can be done more elegant, but this should get you started. Defining the image names as constants in the ImageLocator class avoids spreading the concrete path throughout the project (as long as the name is correct in ImageLocator, everything else will be checked by the compiler)

Your code still uses "C:\Users\Kids\Desktop\Java Game\Cosmic Defense\res\EnemyLv2.png" in Enemy.java. Are you sure this exists? If you moved the Cosmic Defense folder, it will not.
(You were talking about changing absolute paths to relative paths, so this may be your problem)

Part of the reason could be that your code is pointing to an index of "1" in an array of size 1, meaning that the only available index is in fact "0".
Try mobImages[0] = Handler.loadImage("res/EnemyLv1.png");

Better Way to Test Presence of a Value in a Bundle?

I have an activity to play a game. The user may be resuming from a saved state or initiating a new game. If resuming, the identifier for the game to resume is passed to the activity in the bundle. If it is a new game, that part of the bundle isn't passed, and is therefore null. I currently implement this as follows...
Bundle bundle = this.getIntent().getExtras();
int GameNumberToResume;
boolean StartNewGame = false;
try
{
GameNumberToResume = bundle.getInt("GameToResume");
}
catch (Exception e)
{
System.out.println("Exception Catch, so we start a new game.");
StartNewGame = true;
System.out.println((e.toString()));
}
...and it works. StartNewGame drives the decision tree on if we are starting a new one or resuming a saved one, and if we are resuming, GameNumberToResume has the game ID to resume. However, Android Studio throws the soft warning...
Variable 'GameNumberToResume' is assigned but never accessed.
...because in the parts of the decision tree when I need the value of the game to resume, I pull it straight from the bundle via bundle.getInt("GameToResume").
So here's my question: What should I do different? I can make the warning go away by referencing the variable GameNumberToResume downstream instead of pulling it from the bundle, but it doesn't seem to me like that would change anything. The intent of the warning is to point out that I'm wasting memory, and if I do this, I still have two things in scope that both contain the same value.
Is there a way to detect the absence or presence of "GameToResume" in
the bundle without doing a variable assignment in a try/catch loop?
If I move the declaration inside the try part of the loop, then
fire off a System.gc(); after the catch portion of the loop,
would it free up what was used by the variable GameNumberToResume ?
I know in this specific case it probably doesn't matter, but it is simple enough to follow and illustrates a general hole in my understanding of how to efficiently code Android.

Checkout
bundle.containsKey ("GameToResume");
it will return whether this key is there or not in bundle.

Do not use the try-catch here. And you can initialise the game number like int GameNumberToResume=Integer.MAX_VALUE. Then remove the try-catch. Just use if(xx==Integer.MAX_VALUE).
In my opinion, try-catch can only use for the unknown error or unpredictable situation. Here, you know everything.

You can utilize getInt second parameter to put default value, like this.
Bundle bundle = this.getIntent().getExtras();
// Don't forget NullPointerException
if(bundle != null){
final int IMPOSSIBLE_VALUE = -1; // default value
boolean startNewGame = false;
int gameNumberToResume = bundle.getInt("GameToResume", IMPOSSIBLE_VALUE);
if(gameNumberToResume != IMPOSSIBLE_VALUE){
startNewGame = true;
// continue ..
}
}
