[codenameone-discussions] Re: Cn1 still supports J2ME/blackberry?

[Gareth Murfin]

Im presuming lwuit still works if I can go back to that and avoid cn1, will 
give it a go. J2ME is still going in some countries believe it or not, I 
made some stuff for africa and phillipines not that long ago.

[codenameone-discussions] Re: Best way to reuse a container full of components

[Gareth Murfin]

actually its really easy, in gui builder make a "container" not a "form".. 
then you can just get it and put it inside a container in another screen, 
some example code 

 Container ContainerNORTHinset = 
(Container)findByName("ContainerNORTHinset",f);//the place (on your current 
form) where you want to add your reusable container
ContainerNORTHinset.removeAll();//make sure its empty
Container IncludeStudentLifeHeaderSelectTerm  =  
(Container)createContainer(r, "IncludeStudentLifeHeaderSelectTerm"); //HERE 
you instance your container

ContainerNORTHinset.add(BorderLayout.CENTER,IncludeStudentLifeHeaderSelectTerm);//add
 
it to the form

viola, u may also sometimes need

 f.revalidate();

[codenameone-discussions] Re: Exception: java.lang.ArrayIndexOutOfBoundsException - 0 ui.util.Resources.readMultiImage

[Gareth Murfin]

Hi Shai, 

Thanks for the help..
Theyre pngs from client, i did quick add multi images, seems ok, then i 
save and run my app and it gives that error.  
The theme does open yes, but when i go to delete unused images it hangs.
Ive never touched xml team mode so I dont think its on.
It works ok if I dont use multi images and just add image normally using 
"add images"..

Image dimensions are 1080x865, I tried resizing to 1080x864 (in photoshop) 
to be multiple of 8 but it didnt help. In add multi images I tried various 
different source resolutions but it still happened.

[codenameone-discussions] Exception: java.lang.ArrayIndexOutOfBoundsException - 0 ui.util.Resources.readMultiImage

[Gareth Murfin]

For some reason when I add a multiimage using the gui editor, then run my 
app it crashes with the error below. It seems like there is something wrong 
with the image somehow, I tried resaving in photoshop but it always 
happens, the only way to fix it is to replace the .res with a backup one. 
Any ideas whats going on ?

[codenameone-discussions] Codenameone and Unity3D

[Gareth Murfin]

Could I use codenameone to call on android code written in unity? See what 
I want to do is a normal cn1 app but there is a section where I need to use 
a camera to measure the size of someones hand, I dont think this is 
possible in cn1? So I thought I could develop it in unity using ar 
foundation, then set up an interface and call it from cn1 somehow, almost 
just like an intent on android? Any ideas?

Actually I cant figure out what youre doing there.. I never call 
Resources.open, it seems to be done already when it comers into initVars? 
Do I need to do it again and pass the dpi? And why isnt there simply a 
version of getImage() that lets you get images from any DPI?

Also it doesnt seem to work for me, no matter what I call it always gives 
me back the same images:

example inside initVars I do

res= Resources.open("/theme.res", Display.DENSITY_LOW);

or 

res= Resources.open("/theme.res", Display.DENSITY_2HD);

but the images still look identical?

I expected them to be different sizes?

[codenameone-discussions] Scrolling on Y breaks if you use createContainer

[Gareth Murfin]

Ive noticed that if I have a form with a border layout, then use 
createContainer to load a container, add it to the centre of the form. Then 
the scrolling on Y will not work in this container. If I dont use 
createContainer (and just add directly to the form) then the scrolling on y 
works.

Im presuming this is a bug, any work around?

[codenameone-discussions] Scaling images fo tablet

[Gareth Murfin]

I just watched this 
https://m.youtube.com/watch?time_continue=654=sK-u1TBWFX8=emb_logo

But it doesnt really explain what to do on a tablet. For example im testing 
now on galaxy Tab A, lots of my images are small and could take up much 
more of the screen. How do I deal with this without breaking all the sizes 
etc on the mobile where it already looks perfect? 
For now im doing if (isTablet()) and then calling scaledLargerRatio on the 
images (*2), this works but im wondering if it is bad practise?

I am calling the same code when I tap hardware back on android and my own

hardware one sometimes blacks out the screen for a milli second, and I can 
almost see a very fast transition going on which looks a bit ugly. My own 
on screen back button doesnt do that, is there something I can tweak to 
make them behave identically?

[codenameone-discussions] Bluetooth library leaves app on white screen when it turns on bluetooth

[Gareth Murfin]

The Bluetooth library leaves app on white screen when it turns on 
bluetooth, there seems to be no way to get around this, I need to quit app 
and reload to get past it. Has anyone managed to get around this?

[codenameone-discussions] Sidemenu affected by canvas movement

[Gareth Murfin]

My toolbar sidemenu behaves very stranger when im on a custom written 
canvas, the painting of the menu moves along with some stuff that moves on 
my canvas (I have an arrow going up and down and this affects the side menu 
making it move up and down too) is there a way to fix this?

get a reponse Unhandled error code: 400 for

tried r.setReadResponseForErrors(true) with no difference. it looks like 
there is a list of better errors they throw 
like CodeDeliveryFailureException etc, but how do i get which one it is?

[codenameone-discussions] How to use sources?

[Gareth Murfin]

In the old days I could tick include sources,  and then load the project in 
Android Studio.. that doest seem to work anymore. So what are the exact 
steps to actually loading a project in AS? I really need to debug some 
native code :-/

[codenameone-discussions] Re: Can't stack custom component in grid layout

[Gareth Murfin]

Seems to be caused by the components themselves reporting their own size as 
wrong.. I thought they would report the width and height of the space 
availale to them based on the layout theyre added to.

[codenameone-discussions] Can't stack custom component in grid layout

[Gareth Murfin]

So I have a grid layout 2x2, and if I add buttons, they stack as expected. 
For example

myGrid.add(new Button("AAA"));
myGrid.add(new Button("AAA"));
myGrid.add(new Button("AAA"));
myGrid.add(new Button("AAA"));

Adds 4 buttons which sit in each of the cells as expected.

But when I try this with my own custom component (with its own canvas) then 
they dont stack into each cell, they seem to paint over the top of each 
other.  ie if I add 4, they all sit in cell 0,0 (painting over the top of 
each other) which is weird, because I have done this before and it did work 
perfectly. But I cant work out why.. Hopefully that is explained properly, 
any ideas what I am doing wrong?

Re: [codenameone-discussions] Can't assign value '${codename1.version}' to attribute version

[Gareth Murfin]

OK it seems codenameone_settings.properties was overwritten somehow.. it 
was much smaller, I copied one from my backup and things work fine now!.. 
not quite sure why that would happen.

Re: [codenameone-discussions] Can't assign value '${codename1.version}' to attribute version

[Gareth Murfin]

Looks like something has got corrupted, title, packagename, main class, all 
of that is gone.. android signing etc , all my codenameone settings are 
gone. I should have back ups, which files should I copy back? bit of a 
disaster really!..

[codenameone-discussions] Re: Build failed (trying to use a .aar)

[Gareth Murfin]

There seems to be issues with the Android Studios project:

ERROR: Could not determine the class-path for class 
com.android.tools.idea.gradle.project.sync.ng.SyncAction.

And after cleaning and trying again I keep seeing

Build script error, unsupported Gradle DSL method found: 'google()'!

Possible causes could be:  
  - you are using Gradle version where the method is absent (Fix Gradle 
settings)
  - you didn't apply Gradle plugin which provides the method (Apply Gradle 
plugin)
  - or there is a mistake in a build script (Goto source)
Open File


FInally shouldnt it use SDK28 foro google play? seems to be on 27.

None of this would matter if I could test the .arr in the project but I 
cannot compile, and anything I type is considered "OK" by Android Studio. 
ANy ideas how I get a proper working AS project?

just fyi, and in case it comes up again for any of your other customers, 
you create a fullchain,pem file and paste in the root certificate and the 
intermediate certificate from the cert authority and then enable that file 
in the ssl.conf file

SSLCertificateChainFile /root/.ssh/fullchain.pem

then restart the httpd service"

[codenameone-discussions] Re: Build failed (trying to use a .aar)

[Gareth Murfin]

Thanks Shai, it compiles fine now, but I cant work out how to call the 
code. The .aar contains a class called "AlgorithmCWrapper" but I cannot 
seem to import it (ive done a cn1lib refresh).. the interface in the c 
looks like below...

So I expected to be able to do AlgorithmCWrapper cwrap = new 
AlgorithmCWrapper(); 
or maybe
AlgorithmCWrapper my = NativeLookup.create(AlgorithmCWrapper.class);

but AlgorithmCWrapper doesnt import. Ive done this quite a few times but I 
can't see my old code because I'm travelling. How would I get it to work?

package uk.co.skyrad.hobmonitoralgo;
public class AlgorithmCWrapper {
static {
System.loadLibrary("hobmonitor");
}

public native void set_input(byte[] packedBluetoothData, byte hobLayoutId);
public native int[] get_pan_indexes();
public native float[] get_pan_temperatures();
public native int[] get_pan_states();
public native int[] get_pan_boiling_time_seconds();
public native int[] get_time_since_food_added_seconds();
public native void init();
public native void step();}

[codenameone-discussions] Build failed (trying to use a .aar)

[Gareth Murfin]

Hi guys, I am trying to use a .aar for the first time and Im getting build 
failed. 

I think this is the error:

Merging result: ERROR
/tmp/build8355134923580384042xxx/MyApplication/src/main/AndroidManifest.xml:15:17-46
 
Error:
Attribute application@label value=(HobMonitor_V1) from 
AndroidManifest.xml:15:17-46
is also present at [:HobMonitorAlgo:] AndroidManifest.xml:13:9-39 
value=(HobMonitorAlgo).
Suggestion: add 'tools:replace="android:label"' to  element at 
AndroidManifest.xml:15:3-42:103 to override

Is there any way I can do tools:replace from a build hint to fix this? Or 
do I need to adjust the .aar ?

Thanks!
Gaz.

cipher.init(Cipher.DECRYPT_MODE, secretKey, ivspec);

[Gareth Murfin]

Took some time to figure out, it was appearing offscreen! fix is:

For Windows 10 in order to use the old move the window with the cursor keys 
trick you need to have the Shift key pressed when you open the context menu 
from the Task bar.

Painful indeed, it simply wont connect no matter what I do (im presuming

cancel this contract unfortunately. Not sure if its due to the device im 
connecting to which is a rasberry pi but it is meant to be bluetooth LE. Or

Still more issues, connecting I always get "Device previously connected,

thinks its connected to in order to call disconnect/reconnect. And it 
erroneously thinks that I have connected, which I havent.

[Gareth Murfin]

Is there any way to launch it from command line so I can check for errors? 
I really need to add some build hints to get the bluetooth going etc.

I do have that library if you look carefully. I have tried cleaning and
reimporting many times... seems ok on the emulator (ie json lib works) but
on phone it always has that error.

Thanks very much for your reply Kandy.

They look similar (though) not exactly the same as mine.. where did you 
get CN1Bluetooth.cn1lib from? im using theirs which as you can see has a 
spelling mistake, so yours might be different?

[codenameone-discussions] Re: NoSuchMethodError No Direct Method

[Gareth Murfin]

Seems like it should be due to no json lib, but its there, then I realised 
it was only 30k somehow soI grabbed it from here

https://github.com/codenameone/CodenameOneLibs/tree/master/cn1libs

that one was 85k... but now it wont compile  (complains that it cannot find 
ca.weblite.codename1.json.JSONObject; ) , even after doing refresh cn1 
libs. I cannot work out whats going wrong ive used the json lib hundreds of 
times with no issue.

[codenameone-discussions] How to use JNI in cn1?

[Gareth Murfin]

I have a client who wants an Android app done, they have some stuff written 
in native C/NDK, so their files are .so and belong in "jniLibs" - they want 
me to make an app which will utilise this. Assuming I want to use this in 
CN1, how do I go about it? And more importantly, is it possible to use this 
also in the iOS version? What is the route I need to take to use this 
native code on both android/ios? Do I need to rewrite their c in obj-c and 
make a native lib for ios?

Hi, 

Ive made a canvas app that includes some animation of a photograph, its all 
done using code and done in paint(). I would like to save the animation out 
for the purpose of sharing on facebook. Whats the easiest way to do this? 
Im assuming I should write each frame to an image, then construct an mp4 
from the image, but is there any way to create videos like this in 
codenameone ?

[codenameone-discussions] Any voip support?

[Gareth Murfin]

Does CN1 have any way to make voip calls from within an app? Would it be 
feasible to launch skype from cn1, if not ?

Also my client wants to "scan documents" from this app, is there any 
document scanning support for cn1? if not would it be feasible to launch an 
external app to do this? 

I presume you can do this as the QR code scanner appears to work this way.

Cheers,
Gaz

[codenameone-discussions] Dump to binary file

[Gareth Murfin]

Im not sure exactly what I want here, but basically I have to read in a 
.txt file with 164,000 entries, each line needs to be string-tokenized. So 
the code is easy but it obviously takes a lng time to do this in Java 
on a phone or desktop even. So I was wondering is there some other way to 
do it, like do it once and save it as some sort of binary file that can be 
loaded back into the ram at highspeed? Its probably a silly question really 
but I am looking for ways to speed this up because this stuff is used as a 
"realtime" search within the app so I cant exactly force the user to wait 
10 minutes everytime they load the app just to prepare the search data. 

MY CODE:


  hi.add(new Label("START"));
  List allLineObjects = new ArrayList();
  long start = System.currentTimeMillis();
try
{
//The format of the comma-delimited data 
is:{romaji},{kanji},{kana},{English gloss}
//egdoujou,   仝,
 どうじょう, 1. "as above" mark. 
_("Reading in search data now!");
final String fileName = "/searchdata.txt";
InputStream in = 
Display.getInstance().getResourceAsStream(Form.class, fileName);
String fileContents = com.codename1.io.Util.readToString(in);// 
efficient
_("Finished reading ("+fileContents.length()+"), now parse");
  
   List lines_ = StringUtil.tokenize(fileContents, '\n');
   for (int x=0; x3)
{
_(""+x+" ROMANJI: "+romaji+" KANJI: "+kanji+"

LangHolder lh = new 
LangHolder(romaji,kanji,kana,english);

[codenameone-discussions] Re: NFC lib?

[Gareth Murfin]

Haha, do you remember the *hell *I went through last time making the 
AerServ lib? ALMOST KILLED ME :) But yes, I will write an NFC lib, I will 
call it CN1NFC, and I will release it on my github...  so hopefully 
everyone can use it.

I think the hardest bit of the whole thing was simply not knowing about 
this in obj-c: 
dispatch_async(dispatch_get_main_queue(), ^{

so hopefully it will be A LOT easier this time. Cheers.

[Gareth Murfin]

Client needs NFC, can codenameone do this yet? or is it a case of making a 
native lib?

[codenameone-discussions] Re: Downloading image to label automatically

[Gareth Murfin]

No I didnt do anything like that, just ordinary usage. Is there an event 
when the image is downloaded I can tap into to try and do it there?

As for url as name, doesnt seem to matter, this only fails the very first 
time it is downloaded, from then on since it exists its set right away.

[codenameone-discussions] Re: Date parsing different on iOS?

[Gareth Murfin]

So yeah I was substringing date.toString, not a good idea. I changed it to 
be more consistent as shown below, but I still have a weird issue, day of 
the week seems to be 2 days out:

 int DAY_OF_WEEK = cal.get(java.util.Calendar.DAY_OF_WEEK);
switch(DAY_OF_WEEK)
{
case 0: dayName="Mon";break;
case 1: dayName="Tue";break;
case 2: dayName="Wed";break;
case 3: dayName="Thu";break;
case 4: dayName="Fri";break;
case 5: dayName="Sat";break;
case 6: dayName="Sun";break;
}

tells me aug 31 2018 was sunday, but it was friday?
even if I start at case 1: its still one day out, whats happening? sure ive 
been thru this so many times.

SimpleDateFormat dateTodaySDF = new SimpleDateFormat("-MM-dd");
Date dateToday = null; //a date object representing the string they 
passed in
try {
dateToday   = dateTodaySDF.parse(stringDate);
_("dateToday -> "+dateToday.toString());
//do this purely in cn1 so its same on ios and android, no 
toString stuff on dates
java.util.Calendar cal = java.util.Calendar.getInstance(); 
cal.setTime(dateToday); 

int DAY_OF_WEEK = cal.get(java.util.Calendar.DAY_OF_WEEK);

[codenameone-discussions] Date parsing different on iOS?

[Gareth Murfin]

this code runs fine on android and emulator  from my test it produces:
"dateTodayS: Fri Aug 31, dayName: Fri monthName: Aug, dayDate: 31, 
monthNumber:08",

but on real ios it produces:

"dateTodayS: August 31, dayName: Aug monthName: st, dayDate: 1, 
monthNumber:08",

I realise its just parsing different because of the result from parsing the 
date, but shouldnt it behave identically on all platforms?


_("DateStringHolder received "+stringDate);
SimpleDateFormat dateTodaySDF = new SimpleDateFormat("-MM-dd");
Date dateToday = null; //a date object representing the string they 
passed in
try {
dateToday   = dateTodaySDF.parse(stringDate);
String dateTodayS = dateToday.toString();
dayName= dateTodayS.substring(0,3);
monthName  = dateTodayS.substring(4,7);
dayDate= dateTodayS.substring(8,10);
monthNumber= stringDate.substring(5,7);

//for testing differences on ios and android!
Dialog.show("ios debug", "dateTodayS:"+dateTodayS+", 
dayName:"+dayName+", monthName:"+monthName+", dayDate:"+dayDate+", 
monthNumber:"+monthNumber, "OK", "Cancel");
}
catch(Exception e)
{
_("**warning** cant parse date! "+e.getMessage()+"

e.printStackTrace();
}

Re: [codenameone-discussions] MediaPlayer on ios

[Gareth Murfin]

Though one thing ive noticed is that behind the video (presumably where it 
doesnt fit due to ratio or whatever) there is a black background, I need 
this to be white, is there any way?

[codenameone-discussions] Re: Status bar on ios flashes white during transition

[Gareth Murfin]

Well, thats a difficult question to answer because im not sure what you 
mean, well im not sure what the white bar is in the first place. 

My form is a borderlayout, inside "contentpane" I have NORTH, CENTRE, 
SOUTH, but im presuming that is not relevant. So looking at component 
inspector I have what you would expect Toolbar contains StatusBar, and a 
container with 2 buttons with TitleCommand uuid. 

Now I want the text to be white and the background to be whatever the rest 
of NORTH is. So I tried styling StatusBar and TitleCommand, but none of my 
changes have any affect, I delierately used bright colours so it would be 
easy to notice.

I wonder if its related to having the side menu ?? Ive made an animated gif 
to show the issue properly, please excuse the cracked iphone screen :))) 

Any 
ideas?? https://www.dropbox.com/s/oodfxzropqufjhc/20190329_174059.gif?dl=0

Re: [codenameone-discussions] MediaPlayer on ios

[Gareth Murfin]

Thanks, so you're saying I should remove it or set it invisible before 
transitioning to new screen?

Also the "prepare" call doesnt stop the video player being black, the 
controls dont appear either, so instead of a video I just see a black box, 
this works fine on emulators and android.

Re: [codenameone-discussions] MediaPlayer on ios

[Gareth Murfin]

Ive noticed when I leave a screen with the media player on it briefly 
flashes black, is there some way to stop this? like do I need to release it 
before I swap forms or something?

Yes, you can see during the transition the top turns white, before and 
after its fine.

[codenameone-discussions] Downloading image to label automatically

[Gareth Murfin]

I want to be able to download an image and then have it appear in the label 
automatically when its ready, so Im using this:
 
setIconOnMe.setIcon(URLImage.createToStorage(placeHolder, url, url, 
URLImage.RESIZE_SCALE));  

but it doesnt seem to set the image when it comes in? It works fine if I 
revisit the form, but I expected it to download then set automatically, 
should it ?

[codenameone-discussions] Re: Cache a form?

[Gareth Murfin]

Thanks, I tried to cache some forms but it didnt seem to keep the complete 
form. 

For example once I have set up the UI and then populated it, I call this in 
postShow():

cachedForm=getCurrentForm(); 

then if I come back to the form I do 

if (cachedForm!=null)
{  
cachedForm.show();
return;
}

this works but it does not show the changes I made to the form, for example 
most of my forms are full of empty containers, at run time I use 
createContainer to swap in various things I have designed in the gui 
editor, but none of them appear on the cached form.

Did I do it wrong somehow ?

[codenameone-discussions] Finding centre point of an arc?

[Gareth Murfin]

I realise this is not strictly a codenameone question but I have been stuck 
for so long I thought I would ask. I am drawing a pie chart using 
drawArc(), and I want to draw the percentage text in the middle of the arc. 
But, how do I find that x,y point? Is there any way I can use other methods 
in cn1 to help me find this? So far all my attempts to do the maths have 
failed and not a single answer on the web has worked. My maths is not 
exactly AAA, so I am unable to solve this for now!.. Any thoughts would be 
good. Thanks guys, I think its actually quite a tough one though ;-(

[codenameone-discussions] Does compilation remove "empty" methods?

[Gareth Murfin]

So I always make a method like this:

//for printing
private static void _(String s)
{
if (Prefs.DEBUG)
{
com.codename1.io.Log.p(Prefs.ANSI_GREEN+"StateMachine "+s);
}
}

then when it comes to release I set Prefs.DEBUG (which is final) to false, 
would this mean the method was stripped out during compilation? On both 
iOS/Android? Or not ? It's just that during dev I really need A LOT of 
print outs to follow my code, but then for release obviously I dont want 
any. In the old J2ME days I used to do a find and replace on all calls to 
_("hello"); etc before release, but im wondering if that's necessary 
anymore? 

I assume if its not stripped out during compilation then each call even if 
it really does nothing may add up (i do a lot in loops etc) to eventually 
slow certain things down (even by X many ms). But from what I understand 
modern java compilers would remove it since it really doesnt do anything if 
debug is false.

[codenameone-discussions] Delete unused images (old editor)

[Gareth Murfin]

I see when you go to delete used images the editor must scan StateMachine 
these days too, which is great, but ive just refactored a ton of logic into 
their on class for each screen, now delete unused images doesnt scan them 
files. Its a long shot but wondering if theres a way to make it scan them 
all ?

[codenameone-discussions] Cache a form?

[Gareth Murfin]

The set up time for some of my screens takes almost 1 second, so app seems 
unresponsive, I was wondering, is there any way to cache a form? So it 
doesnt have to "build" every time, and do all my logic? Can we store a 
finished form and use that to speed up the app? 

I guess in a way this is kind of like onResume in Android, only onCreate 
does the hard work, and only gets called first time its made.

Ive made a pie chart that draws on canvas, when I add this it doesnt

displaying. Is there anything special I need to do to get my custom
