Android Question GetMethod in reflector fails in API 19

[touchsquid]

Android 4.4 has an API for devices with built in IR transmitters such as the HTC One and many Samsung models. I am modifing my app to work with this.

Dim IR As Reflector
IR.target=IR.getcontext
IR.target = IR.RunMethod2("getSystemService", "consumer_ir", "java.lang.String")
if IR.RunMethod("hasIrEmitter") then 'returns true on my HTC one
Dim test As Object = IR.GetMethod("getCarrierFrequencies", types) 'works
test = IR.GetMethod("transmit", Types) 'error java.lang.NoSuchMethodException: transmit []

The above code works up to the last line. The transmit method is documented here:
http://developer.android.com/reference/android/hardware/ConsumerIrManager.html#transmit(int, int[])

If I call the transmit function with Runmethod4 I get the same error. Does anybody know what I might be doing wrong?

IR.Runmethod4 ("transmit", Array As Object(Freq, pattern), Array As String("java.lang.int", "java.lang.int"))


public void transmit (int carrierFrequency, int[] pattern)

Added in API level 19

Transmit and infrared pattern

This method is synchronous; when it returns the pattern has been transmitted. Only patterns shorter than 2 seconds will be transmitted.


Parameters

carrierFrequency The IR carrier frequency in Hertz.
pattern The alternating on/off pattern in microseconds to transmit.

Your code is incorrect. The second parameter is an array of ints not int.

I recommend you to use JavaObject instead of Reflection. It will be easier to implement it.

Thanks Erel,

I have never used JavaObjext. The examples I found don't seem to correspond. Can you give me a hint how to implement the above code?

pattern is an array of integers.

Got it working. Don't know why getmethod fails but I left it out and used this code to call transmit:

IR.Runmethod4 ("transmit", Array As Object(Freq, pattern), Array As String("java.lang.int", "[I" ))

This helped me a lot! I'll contribute a bit to this thread as well, since I didn't realize this until after someone tested it for me:

In order to use this new API you need to add the appropriate permission to your manifest:

android.permission.TRANSMIT_IR
