How to swtich Accelerometer Axis based on Device?

Question

My android application uses the Y Axis accelerometer to control the character in the game.

This is working fine on most mobile phones, however on my Galaxy Tab 2 10.1, the axis seems to be reversed and I have to manualy change the input for it work.

I would like to write a simple conditional statement that would swap based on device type, however I am unsure what the best practice for this would be. As I am sure someone would have come accross this issue before I ask the question.

How can I determine if the device is a table or a mobile in order to change Accelerometer axis?

Answer 1

I found out the best way to do this is to check the screen size on the device and base a boolean conditional to device on which axis to use. This is tested and working great.

// Check the screen layout to determine if the device is a tablet.

public boolean isTablet(Context context) {
    boolean xlarge = ((context.getResources().getConfiguration().screenLayout & Configuration.SCREENLAYOUT_SIZE_MASK) == 4);
    boolean large = ((context.getResources().getConfiguration().screenLayout & Configuration.SCREENLAYOUT_SIZE_MASK) == Configuration.SCREENLAYOUT_SIZE_LARGE);
    return (xlarge || large);
}

// Changle Accelx or Accely input based on the above (Im using OpenGLES 1.1)

if (isTablet(glGame)) {
    world.update(deltaTime, game.getInput().getAccelX());
}
if (!isTablet(glGame)) {
    world.update(deltaTime, game.getInput().getAccelY());
}
