Using the accelerometer

[mikegriffin]

Its kinda hacky but I have the acceleromter working using the following code:



[java]

package sg.edu.sp.dmit.ANBDemo;



import android.hardware.Sensor;

import android.hardware.SensorEvent;

import android.hardware.SensorEventListener;

import android.hardware.SensorManager;

import android.os.Bundle;

import android.util.Log;



import com.jme3.app.AndroidHarness;

import com.jme3.system.android.AndroidConfigChooser.ConfigType;







public class MainActivity extends AndroidHarness implements SensorEventListener{



private SensorManager sensorManager = null;



Test20 test20;



@Override

protected void onResume() {

super.onResume();

// Register this class as a listener for the accelerometer sensor

sensorManager.registerListener(this, sensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER), SensorManager.SENSOR_DELAY_NORMAL);

// …and the orientation sensor

sensorManager.registerListener(this, sensorManager.getDefaultSensor(Sensor.TYPE_ORIENTATION), SensorManager.SENSOR_DELAY_NORMAL);

}



@Override

protected void onStop() {

// Unregister the listener

sensorManager.unregisterListener(this);

super.onStop();

}



@Override

public void onCreate(Bundle savedInstanceState)

{

super.onCreate(savedInstanceState);

sensorManager = (SensorManager) getSystemService(SENSOR_SERVICE);

}



public MainActivity() {

using test20=(Test20) getJmeApplication();



lets you hook into the simpleapplication and in theory you could use the gesture recogniser

http://developer.android.com/resources/articles/gestures.html

and/or event voice control

http://developer.android.com/resources/articles/speech-input.html



I’m thinking for the voice recognition - commands to a virtual 3d pet etc.

oh sweet, thanks i will be stealing this

[rastikko]

Itersting code, right now im trying to create hello world in android.



I´ve been able to compile the begginers tutoriales in my mobile, the problem comes when i try to use advance fetures with android.



I have to create an alternative way for the proyect. In my test expierence i use the option to use as an android application changing it from mobile option in project properties.



Should i create the project in an alternative way as it explain in this post to use android options?



http://hub.jmonkeyengine.org/groups/android/forum/topic/how-to-run-your-jme3-application-on-android-androidharness/



Thanks.

PD. Here is the error that i get when i try to compile the code.

[rastikko]

Ok solved, iv just comment the

//import android.util.Log;



and all other lines that use the Android Log in the jmoney Main code.



Change in MainActivity the



appClass = “sg.edu.sp.dmit.ANBDemo.Test20”; // clickable hud navigation buttons & accelarometer



to



appClass = “mygame.Main”; // clickable hud navigation buttons & accelarometer



and add the import



import mygame.Main;

[normen]

Exactly, this class doesn’t properly separate android and jme code so it can only be used on android and not with a normal platform-independent jme project:
