我有这样的问题：我的传感器大部分工作正常。但有时传感器在三星 Galaxy Gio 上不起作用。可能是关于设备规格。在运行时我得到了这个错误，但没有产生崩溃。只是传感器不起作用，我的球不会通过传感器产生的重力移动。

这是我刷新重力的代码：

@Override
public void onAccelerometerChanged(AccelerometerData pAccelerometerData) 
{
    float k = 10f;
    Vector2 gravity = null;
    if(mLevelScene.isWaterExist)
    {
        if((mLevelScene.ballPlayer.oAnimatedSprite.getX() > mLevelScene.waterCoordinates[0] && mLevelScene.ballPlayer.oAnimatedSprite.getX() < mLevelScene.waterCoordinates[0] + mLevelScene.water.oTextureWidth) &&
                (mLevelScene.ballPlayer.oAnimatedSprite.getY() + 32 > mLevelScene.waterCoordinates[1] && mLevelScene.ballPlayer.oAnimatedSprite.getY() < mLevelScene.waterCoordinates[1] + mLevelScene.water.oTextureHeight))
        {
             gravity = Vector2Pool.obtain(pAccelerometerData.getX()*k, pAccelerometerData.getY()*k - ( (mLevelScene.ballPlayer.oAnimatedSprite.getY() - mLevelScene.water.oSprite.getY())*3/4 + 20));
             mDampingCount = 2.0f;
        }
        else
        {
            gravity = Vector2Pool.obtain(pAccelerometerData.getX()*k, pAccelerometerData.getY()*k);
            mDampingCount = 1.5f;
        }
    }
    else
    {
         gravity = Vector2Pool.obtain(pAccelerometerData.getX()*k, pAccelerometerData.getY()*k);
         mDampingCount = 1.5f;
    }

    mPhysicsWorld.setGravity(gravity);
    Vector2Pool.recycle(gravity);
}
