my arduino configured for constant cyclic transmission at a rate of 57600. he cannot accept anything now, he has to change it.
it runs when detect the suit hardware

Edit manifest.
Wait 5 minutes.
upload this to arduino

It seems to me that it is much more reliable to simply receive messages from arduino at a speed of 57600. I see this in the terminal program.
let’s just try to get something! there is no point in changing the arduino, I can not run any sketches on the phone, they collapse when accessing the usb initialization line. and your last program crashed too. nothing works on the phone, no screen!
Serial.list (this) [0]
!!! Full crash programms!!!
it seems like one single library does not work well.
i am going to check all and inform you

No ellipse!
If delete line “if (Serial.list(this)[0] ==null){temp=0;}” -ellipse draws well

- polling the list of USB devices Serial.list (this) [0]
- based on point 1. setting port = new Serial (this, Serial.list (this) [0], 57600);
- read / write to port
dies in the first paragraph. the second and third paragraph are now irrelevant!
I am trying to repeat your successful feat.
I just need to take the last step to victory. how did you install the library you specified in APDE?
after all, this library lacks the elements necessary for connection, namely:
jar files are missing in the “libraries” folder! How did you manage to connect such a library to APDE? You wrote in your post that you did it. Did you convert the library with something, if so, how and with what?
@paulgoux
I saw that you are very good at libraries, please tell me how and with what I can recompile libraries from github so that they work on android in APDE (there is .jar, there is a folder “library”)?
I have seen the advice that this can be done using the “terminal ide”, but I have not found detailed instructions on how to do this anywhere. What are the options? I would be grateful for your help!
Im not particularly great with libraries, i jave an android repo that you can make use of ive posted it on the repo however i think ive figured out how to get any library onto android.
Take a look at the process.
Navigate to the library settings in apde until you get to this screen
Press dx dexer
Select the library you want to dex.(Note the ext requirements)
Then take a look at the files contained in the folder and their names.
As you can see i am dexing the fileWriter.jar library and so i need to name the output file fileWriter-dex.jar. Apde will dex your file and then you are good to go, i had no more crashes after this on my device.
Ive also managed to run my sketch with the jserial lib ive linked in a previous post.
i cant help any further as i dont have an arduino.
Ps
This is actually the solution posted by @jafal earlier in thread.

and doesn’t need arduino.
the question is not about the robustness of the libraries, but about how to glue them to APDE.
I got it pretty good with dfx, use many days.
but where do I get the .jar files?
try sticking the serial port library used by @glv . the link in the previous post is just above. Just stick it on, you don’t have to run it.
Youll have to go with your preferred library, download them with a google search and copy the jar files into the appropriate folders.
The library im referring to was posted near the top of the convo, unfortunately its hard to scroll through such a long thread.
As for how to build libraries for android with eclipse.
Unfortunately i do not know how to do this in apde.
Now ive followed the thread as best i could and im pretty sure weve all posted solutions that work.
Help me understand which method you are using and what steps your are struggling with if anything.
Again following these steps i have managed to load the library with apde and run a sketch.
I jave not jeeded to amend any manifest or amend apde in any way.
Download the jar
Add the jar to your library folder with the appropriate folder structure.
Import lib in apde.
Dex lib in apde.
Add import to the sketch.
To confirm i have made no use of the pc here to achieve any of this, phone only.
Done

Thank you and so i can understand, can you please explain the purpose of adding the device filter, is this a requirement for the library or the usb connection?
Also here is a link to the library @jafal was using

your code completely works 100%.
full match of manifest files and device_filter.xml.
BUT!
THE LIBRARY THAT YOU USED ON YOUR PERSONAL COMPUTER, COULD YOU INSTALL (ADHESIVE) TO YOUR PHONE-ANDROID-APDE?
it is indicate that hardware connected and determined the usb driver chip there is other device filter files could be used i am going to compile sketch with out this file and see what happen
