Rename whole class/method:

• AdkManager
• readText / sendText

Now is: http://docs.adktoolkit.org/

In this way we can initialize the AdkManager instance through:

mAdkManager = new AdkManager(this);

Hi,
for some hours I'm trying to connect my Android phones with my Arduino Mega ADK. I tried this library too, but regardless what I did, the results are very unstable.

I saw the example sketch in this repo.

• Which USB-Host library are you using? I cannot compile it because the USB-Host lib that I use does not have those read and write methods.
• How reliable does the connection between Android and Arduino work for you?
• Do you have some tips or a more complete example that works for you?

Nexus 6

My Nexus 6 seems not recognise the Arduino.

• The intent filter in the AndroidManifest.xml seems not to work, the app is not started.
• UsbManager#getAccessoryList() does not return results
• Adk#isReady() returns always false

Just once the Android App was started when I connected the phone with the board and I could send and receive data. But after that it did never work again. I can see a 'USB device connected' notification for some seconds but nothing else happens.

Galaxy Nexus

My Galaxy Nexus works better. Very often the usb connection works and I can send and receive.

• I have to press the reset button on Arduino and reconnect the phone several times to establish a connection
• After Killing the Android app and restarting it the connection does not work again

My setup:

• Example (Arduino sketch and Android app) that I'm using ArduinoBlinkLED
• USB-Host-Shield-20
• Arduino Mega ADK
• Galaxy Nexus with Cyanogen 11 (Android 4.4.4)
• Nexus 6 with stock ROM, Android 5.1.1

For developers usage:

• strip README only with essentials
• documentation with usage explanation
• simple tutorial (serial echos) in docs

Use application context in ADK constructor and use it with Android API version checking:

• case "add-on library" -> API 10
• case "platform apis" -> API 12

Because this library doesn't need any Android resources, it can be assembled as a JAR library. This allows Eclipse to use the library without any import problem

The documentation should say that one needs to resume and close the adk in onResume and onPause respectively.

Thanks for finding this out at the hackathon at cebit, palazzen! ;)

Hi all,

I'm using this tutorial by UDOO to communicate with the Arduino board from Android:
http://www.udoo.org/tutorial/android-arduino-udoo-simple-hello-world-tutorial/. I have updated the Android dependency to 0.3 and successfully flashed the Arduino sketch, but when I run the Android app, I get:
java.lang.SecurityException: User has not given permission to accessory UsbAccessory
on the adkManager.open(); call.

Any idea how to solve this?

Thank you.

It should use StringBuilder to publishProgress of a String object as result

Create an IMessage interface for the AdkMessage class that exposes:

• getString()
• getFloat()
• getByte()
• getBytes()
• getInt()
• ...

In this way a developer can simply use mAdkManager.read().getInt() to read an Int value from the ADK.

Pros:

• better abstraction
• avoid developers to parse returned value

Cons:

• lesser control and flexibility for returned result
