coding is hard and some struggle to learn, but if i can give some positivity, its that after a while eventually things begin to make sense, then all those things we struggled with become understanding.

@ZENAR57 Did you get serial working in your development environment (APDE, Android only and no PC)?

> [@ZENAR57](#):

> Have you actually started serial data transfer using these libraries in practice?

I have now!  
I did this with Processing for Android (development on PC) to test the library.

I followed instructions on this site:

> **[GitHub - inventit/processing-android-serial: Android Serial Library for...](https://github.com/inventit/processing-android-serial)**
>
> Android Serial Library for Processing. Contribute to inventit/processing-android-serial development by creating an account on GitHub.

I got an OTG cable yesterday.

I wrote a very minimal sketch:

- Arduino Mega is is counting up and sending data every 500ms.
- Android is receiving and display count to the screen.

It is working!

I may try your approach in the future but not anytime soon. I am very busy these days.

`:)`

the problem of library operability is no longer considered and faded into the background. Having problems editing apk access rights to hardware resources,without resorting to the help of a computer at all.

I probably missed it, it’s a pity, I had to spend time to figure it out myself.

you have a computer and everything that worked for you was the result of the computer’s help. Try to do everything with a blank slate without touching the computer.  
I also have everything working in hardware, I can receive and transmit data from other programs. but can’t use APDE processing.

this file is not that big issue it is used just if you want the sketch to indicate if the Arduino connected or not so if you have the suit setting of the library and working code you do not need this file

**2.** If the app should be notified when a device is attached, add [device\_filter.xml](https://github.com/mik3y/usb-serial-for-android/blob/master/usbSerialExamples/src/main/res/xml/device_filter.xml) to your project’s `res/xml/` directory and configure in your `AndroidManifest.xml` .
