我刚刚将一个应用程序重构为框架库和应用程序,但现在当我尝试在模拟器中启动应用程序时,我得到以下错误堆栈跟踪:

我最近向市场发布了一个应用程序,我现在收到一些用户的错误,该应用程序可能会在启动时崩溃.不幸的是我无法直接与他联系,该应用程序在模拟器以及我的手机(以及一些朋友的手机)上工作正常.
编辑:我想这会发生在多个用户身上,因为我在市场上收到的评论就像"开始时崩溃"或"不起作用".我只收到了这一个堆栈跟踪,但没有关于配置,设备,Android版本等的信息.

该应用程序是一个简单的音板,所以没有任何魔术,但我无法理解为什么它在某些手机上失败.这是我得到的堆栈跟踪,我希望有人可以帮助我:

这些是我活动的前几行:

public class SoundMachine extends Activity {
  private SoundManager mSoundManager;

  @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

编辑:这是(几乎)完成onCreate:

  @Override …
