iOS Failed to create directory (can ios handle chinese in paths??)

My app works on simulator and android, it extracts a zip to FileSystemStorage, however it fails on ios and I see this error:

<Notice>: Failed to create directory /var/mobile/Containers/Data/Application/B8F1A094-A60C-4D14-A155-B5C141924EE4/Documents/com.outlier.lang///extracted/html-data/entries/kanji/\M-h\M^R\M-&/

The paths actually contain chinese characters, which I assume is the issue, but seems odd that it works fine on android and simulator.. Does anyone know if its possible to write folders/files with chinese characters on ios ?

I think this might be related to the three /// characters. How did you generate that path?

hmm when i print the contents of storage only cn1preferences and cnlog exist, its as if ios is wiping or not letting me write any files at all..

i really hate iphone.

basically nothing will save to the iphone, you can see if fails to make any directory, im using a normal test zip no weird characters but still it wont write, works perfectly on android and sim. im so confused right now, wasted entire day on this.

Well im now coming to the conclusion there must be some sort of bug in cn1 which will not allow writing to iphone storage. 10 hours of trying with no luck, and no clue what to do next, have you ever tried unzipping to FileSystemStorage on an iphone? im using cn1 zipsupport.

OK so I did a quick test bed to show my issue, and it seems to prove that somehow you cannot unzip on iphone

steps

1-new project

2-in start() put this code

System.out.println("TEST ZIP ON IPHONE");

InputStream zipFile = Display.getInstance().getResourceAsStream(Form.class, "/testzipfolder.zip");

Unzip(zipFile, "extractedtest");

String filesFoundx="";//for debug

for(String file : Storage.getInstance().listEntries())

{

filesFoundx+=file+"\n";

}

Dialog.show("DEBUG",filesFoundx, "Ok", null);

use this unzip method, this works on android/sim, Its not quite same as the one on the zipsupport github page because that code doesnt work correctly (if this method is somehow wrong here id like to know why but seems to work fine)

public static void Unzip(InputStream is_zipFile, String str_dirDest)

{

InputStream is;

try

{

is = is_zipFile;

ZipInputStream zipStream = new ZipInputStream(is);

ZipEntry entry;

// create a buffer to improve copy performance later.

byte[] buffer = new byte[2048];

while ((entry = zipStream.getNextEntry()) != null)

{

FileSystemStorage fs = FileSystemStorage.getInstance();

String str_name = entry.getName();

String str_outdir = FileSystemStorage.getInstance().getAppHomePath();

if (str_outdir.length() > 0)

{

str_outdir = str_outdir + "/" + str_dirDest;

}

String outpath = str_outdir + "/" + entry.getName();

OutputStream output = null;

try

{

if (entry.isDirectory())

{

fs.mkdir(str_outdir + "/" + str_name);

continue;

}

else

{

File file = new File(str_outdir + File.separator + str_name);

File parent = file.getParentFile();

if (!parent.exists())

{

parent.mkdirs();

}

output = FileSystemStorage.getInstance().openOutputStream(outpath);

int len = 0;

while ((len = zipStream.read(buffer)) > 0)

{

output.write(buffer, 0, len);

}

catch (Exception e)

{

e.printStackTrace();

Dialog.show("Unzipping Error!", ""+e.getMessage(), "OK", null);

}

finally

{

if (output != null)

{

output.close();

}

} catch (IOException ex) {

Log.p(ex.getMessage(), 0);

Dialog.show("Unzipping Error!", ""+ex.getMessage(), "Ok", null);

}

- run on simulator observe dialog shows "extractedtest" dir has been made

- run on iphone, observe it is not there (and errors making dirs)

output:

Try:

if(str_outdir.endsWith("/")) {

fs.mkdir(str_outdir + str_name);

} else {

fs.mkdir(str_outdir + "/" + str_name);

}

Also check that str_name doesn't include / within it. You can test both in the simulator but failure will probably only show on the device as it's more sensitive to these nuances.

thanks shai.. no luck unfortunately, i made sure there was no ///

but i still see

I even wrote a simple test to simply make a dir, but it always fails on iphone, it is as if you cannot make dirs on iphone at all.. but surely someone would have noticed by now...

this code

FileSystemStorage fs = FileSystemStorage.getInstance();

fs.mkdir("ZZZTESTA");

fs.mkdir("ZZZTESTB");

String testpath = fs.getAppHomePath()+"/xxxtesta";

fs.mkdir(testpath);

String testpathb = fs.getAppHomePath()+"xxxtestb";

fs.mkdir(testpathb);

results in

files dont even write on ios, im assuming this is a cn1 one bug by now.

try

{

String root = FileSystemStorage.getInstance().getAppHomePath();

OutputStream os = FileSystemStorage.getInstance().openOutputStream(root+"testfile.txt");

os.write("arse".getBytes());

_("arse written");

_("does it exist? "+FileSystemStorage.getInstance().exists(root+"testfile.txt"));

}

catch(Exception e)

{

_("cant write file "+e.getMessage());

}

####StateMachine arse written

its weird because i just tried and rebuilt another app ive done in cn1, it downloads pdfs to fileststemstorage, that work fine still

it uses

Util.downloadUrlToFileSystemInBackground(url, FileSystemStorage.getInstance().getAppHomePath()+savedFileName, new ActionListener(){

@Override

public void actionPerformed(ActionEvent evt) {

_("%%%%%%%%%%%%PDF download complete%%%%%%%%%%%%%%%");

}

});
