Cannot find symbol Accelerometer

gspot38

Hello everybody!

I just reinstalled android sdk tools and I followed the instruction found in this link http://wiki.processing.org/w/Android#Instructions to make processing work with android..

I said "reinstalled" because over the last year I had (silly) reasons to install/uninstall android sdk and java. depending on some tutorials..

So today I decided to follow a tutorial on processing where the code has just a few lines..

#############################
    Accelerometer accel;
    void setup(){
    accel = new Accelerometer();
    }


    void draw(){

      println(accel.getX());

    }
#############################

It is supposed that I do not need to do anything in order to make accelerometer work (like import or something like that) but when I try to run it (directly on my device Nexus 5) it will produce the following error..

Any idea please? I know I am doing something wrong but I cannot figure out what..

Thanks!

Here is the full message from Processing

It looks like you're missing a class called Accelerometer. I don't know where this class would come from other than an example, such as one included with the Processing distribution, or perhaps with Ketai. There is a Processing example called "Accelerometer" (in the "Sensors" folder) that includes an AccelerometerManager class.
