I just want to have 2 Objects from Type "Media". Therefore i have 2 .mp3 files.
The first is no problem, i can play it.
But if i enable the Code for the second file, the System throws an Error
"InvocationtargetException" it says "System can not find the file"
I checked both paths of the .mp3 files, here are the results:
file:/C:/Users/Lennie-Admin/Documents/NetBeansProjects/Lost/Rise.mp3
file:/C:/Users/Lennie-Admin/Documents/NetBeansProjects/Lost/TrueStrength.mp3
I checked my working directory with System.out.println( new File("").getAbsolutePath()); the Result is
C:\Users\Lennie-Admin\Documents\NetBeansProjects\Lost
And finally here is the java Code, which should create the 2 Objects:
String uriString1 = new File("Rise.mp3").toURI().toString();
Media hit1 = new Media(uriString1);
String uriString2 = new File("TrueStrength.mp3").toURI().toString();
Media hit2 = new Media(uriString2);
Hope you can help me :)

How to delete all files in the temp device directory but leave 10 latest with mime type 'audio/mpeg'.
Thanks
Iterate through the folder, read the mime type and leave at least 10 files there?
The MIME type can be retrieved as shown in this answer.
Now all that's left is to iterate through the files, where the MIME-type is the desired one, and delete all but 10.
Directory dirToPrune = ...;
List<File> result = [];
for(FileSystemEntity entity in dirToPrune.listSync())
if(entity is File && lookupMimeType(entity.path)=="audio/mpeg")
result.add(entity);
while(result.length > 10) {
File toDelete = result[0];
result.removeAt(0);
toDelete.delete();
}
I did not test the code but the idea should be clear.
I made a word game app for android in Unity, where the player has to find a word from a category previously loaded to the game.
The way I load the categories is:
There is a folder named Categories, inside Assets, I run through the folder and read each text file as a category.
The categories are stored in a dictionary where the key is name the of the file and the value is every line of the file as an array element.
It worked well on the PC however no luck on android. Tried changing the path to
"public string categoriesDirectoryPath = Application.persistentDataPath +"Categories";" still does not work.
Original path was "Assets/Categories"
Code for initiating the dictionary with the file values is (Happens on GameManager's Awake()):
private Dictionary<string, string[]> createCategories(string directoryPath)
{
Dictionary<string, string[]> categories = new Dictionary<string, string[]>();
string[] categoryPaths = Directory.GetFiles(directoryPath);
foreach (string path in categoryPaths)
{
if (!path.EndsWith("meta")) {
Debug.Log(path);
string categoryName = Path.GetFileNameWithoutExtension(path);
Debug.Log(categoryName);
string[] categoryData = File.ReadAllLines(path).ToArray();
categories.Add(categoryName, categoryData);
}
}
return categories;
}
Is there a way of iterating the folder and reading the text files that were in Assets/Categories after building the APK?

No.
If you want to access from the project, in a build, you have two options:
1.Put the file a folder named "Resources" then use the Resources to read the file and copy it to the Application.persistentDataPath path. By copying it to Application.persistentDataPath, you'll be able to modify it. Anything in the "Resources" is read only.
2.Put the file in the StreamingAssets folder then use UnityWebRequest, WWW or the System.IO.File API to read it. Atfer this, you can copy it to the Application.persistentDataPath.
Here is a post with code examples on how to do both of these.
3.AssetBundle(Recommended due to performance and loading reaons).
You can build the file as AssetBundle then put them in the StreamingAssets folder and use the AssetBundle API to read it.
Here is a complete example for building and reading AssetBundle data.
I have written a patcher for my game but I am stuck at the actual saving of the files part. I keep on getting the following error from unity:
System.ArgumentException: Name has invalid chars
at System.IO.FileStream..ctor....
Here is the code that is in charge of saving my files:
function downloadFile(file:String){
var download:WWW = WWW(rawDataFolder+""+file); //download file from platforms raw folder
yield download; // wait for download to finish
// var saveLoc = Application.persistentDataPath; //Location where the files will go
var saveLoc = "C:\\games";
try{
Debug.Log(saveLoc+"\\"+file);
File.WriteAllBytes (saveLoc+"\\"+file+".FILE", download.bytes); //<----PROBLEM HERE.
}
catch(error){
updateMsg ="Update Failed with error message:\n\n"+error.ToString();
errorOccured = true;
Debug.Log(error);
}
}
I am trying to download a file called "level0". It doesn't have a file extension... in windows explorer it says it is simply 'FILE'. So I was thinking it was a binary file. Am I wrong? What might be causing my null character problem? This missing extension? Any help on this would be amazing.
I found out that my problem originated in the text file that I was reading. The text file must have had spaces in it. Using the ".Trim()" command I was able to remove the invalid char error. Once that was removed it worked perfectly reading files without extensions (Binary Files).
I have a file called SAVE.txt. It is in the same package as the class k. The problem is I can't write anything in the .txt file using the following code inside k:
File saveButton = new File ("SAVE.txt");
BufferedWriter output = new BufferedWriter (new FileWriter (saveButton));
output.write("something");
output.close();
Can anyone help me with this?
bw = new BufferedWriter(new FileWriter("filepath",true));
bw.write("Hello World!");
bw.write("\n");
bw.write("Hello World 2 !\n");
bw.write("Hello World 3 !" + "\n");
bw.close();
Try this?
Did you try something easy like this:
FileWriter f = new FileWriter("test.txt");
f.write("hello");
f.close();
When you write new File ("SAVE.txt"), since you specified a relative path, it refers to a file SAVE.txt in the current working directory. The current directory is in general completely separate from the directory corresponding to your Java package.
When you run code in Netbeans, it should be possible to specify the working directory (look in the project settings). Set it to some well-defined location, like the root of your project. Now specify the path relative to that working directory. For example, you could use new File ("out/SAVE.txt").
I have a file reader channel picking up an xml document. By default, a file reader channel populates the 'originalFilename' in the channel map, which ony gives me the name of the file, not the full path. Is there any way to get the full path, withouth having to hard code something?
You can get any of the Source reader properties like this:
var sourceFolder = Packages.com.mirth.connect.server.controllers.ChannelController.getInstance().getDeployedChannelById(channelId).getSourceConnector().getProperties().getProperty('host');
I put it up in the Mirth forums with a list of the other properties you can access
http://www.mirthcorp.com/community/forums/showthread.php?t=2210
You could put the directory in a channel deploy script:
globalChannelMap.put("pickupDirectory", "/Mirth/inbox");
then use that map in both your source connector:
${pickupDirectory}
and in another channel script:
function getFileLastModified(fileName) {
var directory = globalChannelMap.get("pickupDirectory").toString();
var fullPath = directory + "/" + fileName;
var file = Packages.java.io.File(fullPath);
var formatter = new Packages.java.text.SimpleDateFormat("yyyyMMddhhmmss");
formatter.setTimeZone(Packages.java.util.TimeZone.getTimeZone("UTC"));
return formatter.format(file.lastModified());
};
Unfortunately, there is no variable or method for retrieving the file's full path. Of course, you probably already know the path, since you would have had to provide it in the Directory field. I experimented with using the preprocessor to store the path in a channel variable, but the Directory field is unable to reference variables. Thus, you're stuck having to hard code the full path everywhere you need it.
