Irrespective of the reason, not obtaining Camera handle is a case that needs to be handled with proper error handling. In the current case in your Pause handler, is the Camera instance being released ? Check for proper usage at http://developer.android.com/training/basics/activity-lifecycle/pausing.html
I have creating this treetable
Now I want to sum up th children values and show the result in the parent cell under the related column. For example for Function 7 in column 2 and row 2 I want to right 2.0, and for Function 11 column 4 row 4 right 1.0 (function 12 + function 13)

TreeMap temp clones dc.getFuncTypeOrg(). In this TreeMap I have value for each child (color and the number). then in cellfactory i multiply value in color ( green = 1 and yellow = 0). Outside the loop I thought to make a treemap containg each parent as key and all it's children as value. Then I can sum up children values together and make a treemap in which first key is parent and as value the required value(or just string ArrayList ). After that I can check the name of cell in cellFactory and if it is a parent just right the value in the cell. I have been told how i can get treeitem values, and i am now here :
//after col loop ends
TreeMap<String, List<TreeItem<String>>> mytreemap = new TreeMap<>();
TreeMap<String, List<String>> parChild = new TreeMap<>();
for(TreeItem node: root.getChildren()){
if(!node.isLeaf())
mytreemap.put(node.getValue().toString(), node.getChildren());
}
for(Entry<String, List<TreeItem<String>>> ent: mytreemap.entrySet()){
for(TreeItem myItem : ent.getValue()){
// how can i fill parChild with parent as key and all its children as value?
System.out.println(ent.getKey()+" "+myItem.getValue());
}
}
treeTable.setPrefWidth(1200);
treeTable.setPrefHeight(500);
treeTable.setShowRoot(false);
treeTable.setTableMenuButtonVisible(true);
return treeTable; }
Here at setCellFactory
else if (item.contains("parent")) {
for (int i = 0; i < dc.getFuncTypeOrg().size(); i++) {
}
i can get the roots. Is there a way to do a recursion (up to the number of children and subchildren for that root cell) and add their value together and setText the parent cell to that value?
You can use onEditCommit method to add all childern values and show them in parent cell. For example
column1.setOnEditCommit((evt) -> {
//finalsing value of the cell
evt.getRowValue().getValue().setCellValue((evt.getNewValue()));
//Returns all the sibblings of the current cell
ObservableList<TreeItem> children = evt.getRowValue().getParent().getChildren();
int parentValue = 0;
for (TreeItem<> child : children) {
parentValue = parentValue + Integer.valueOf(child.getValue().getCellValue());
}
evt.getRowValue().getParent().getValue().setCellValue(parentValue);
});
Today I was going to pack my game into a Jar to provide to a friend who codes and wanted to see a nice glitch I managed to create. When I went to make it a Runnable jar it would load up in the Command Prompt but throw Resource Not Found errors for Sounds (.ogg's), which was fine because they werent going to be used in the Debug mode it was set to. Then it threw a NullPointerException in TileHanlder.class at initTileMap() line 137.
I am at a loss so I came to StackOverflow because I have spent nearly my entire day on getting a working Jar. I have also tried JarSplice.
My main question is if there is any anomalies you notice or something I didnt do that is leading to resources not being found in the .jar.
ALL CODE AND RESOURCES WERE IN THE SAME JAR, ONE JAR FOR EVERYTHING there were not multiple jars

If You need ANY other resources or information than please let me know and I will be happy to provide so I can get over this. I will also be thinking of other ways, Thank you for any responses!
THINGS WERE CUT OUT DUE TO THE 30k Char Limit on the question text box. Mostly in the insanely crowded AssetHandler.java, it is still there in the git repository though.
I had the very same problem. After searching for a while, I came across this neat solution. See this LWJGL forum post.
public static void main(String[] args) throws SlickException {
/* Set lwjgl library path so that LWJGL finds the natives depending on the OS. */
String osName = System.getProperty("os.name");
// Get .jar dir. new File(".") and property "user.dir" will not work if .jar is called from
// a different directory, e.g. java -jar /someOtherDirectory/myApp.jar
String nativeDir = "";
try {
nativeDir = new File(GameMain.class.getProtectionDomain().getCodeSource().getLocation().toURI()).getParent();
} catch (URISyntaxException uriEx) {
try {
// Try to resort to current dir. May still fail later due to bad start dir.
uriEx.printStackTrace();
nativeDir = new File(".").getCanonicalPath();
} catch (IOException ioEx) {
// Completely failed
ioEx.printStackTrace();
JOptionPane.showMessageDialog(new JFrame(), "Failed to locate native library directory. " +
"Error:\n" + ioEx.toString(), "Error", JOptionPane.ERROR_MESSAGE);
System.exit(-1);
}
}
// Append library subdir
nativeDir += File.separator + "lib" + File.separator + "native" + File.separator;
if (osName.startsWith("Windows")) {
nativeDir += "windows";
} else if (osName.startsWith("Linux") || osName.startsWith("FreeBSD")) {
nativeDir += "linux";
} else if (osName.startsWith("Mac OS X")) {
nativeDir += "macosx";
} else if (osName.startsWith("Solaris") || osName.startsWith("SunOS")) {
nativeDir += "solaris";
} else {
JOptionPane.showMessageDialog(new JFrame(), "Unsupported OS: " + osName + ". Exiting.",
"Error", JOptionPane.ERROR_MESSAGE);
System.exit(-1);
}
System.setProperty("org.lwjgl.librarypath", nativeDir);
}
Bear in mind that you need a lib folder in the same directory. I have mine stored outside of the .jar, but it may be possible to have it inside as well. Also note that it needs to happen before you do any LWJGL stuff, so the main method is a good place.
