Question

当我使用eclipse在手机上运行我的应用程序时我完全没有问题，但是当我签署我的应用程序然后将其安装在我的设备上时，我得到了ClassNotFoundException。

android无法找到的类是一个扩展Application的静态上下文类：

public class ProjectContext extends Application{

    private static Context context;

    public void onCreate() {
        super.onCreate();
        ProjectContext.context = getApplicationContext();
    }

    public static Context getAppContext() {
        return ProjectContext.context;
    }
}

栈跟踪

我不知道出了什么问题。我希望有人可以帮助我。

编辑：

private static SharedPreferences getData = PreferenceManager.getDefaultSharedPreferences(NzbManagerContext.getAppContext());

带有静态上下文类的ClassNotFoundException
