Java Android ClassNotFoundException位于另一个包中的源文件上

通过尝试访问单独包中的类，我成功地获得了由

ClassNotFoundException

引起的

NoClassDefFoundError

我已经编写了代码，通过按下按钮调用堆栈跟踪下面的函数来重现这个问题

没有任何意义的是，即使我在项目中有源文件，它也找不到类

堆栈跟踪：

请注意，上面的stacktrace仅在我第一次按下按钮时生成。随后的按钮按下会产生一个较短、稍有不同的版本（见下文）

导致错误的代码部分：

// this is from the OBDTaximeter class, and is called whenever I press a specific button. I have a try/catch where I'm calling it to log the error above
private void doBindService() {
    if (!isServiceBound) {
        Log.d(TAG, "Binding OBD service..");
        if (preRequisites) {
            Intent serviceIntent = new Intent(this, ObdGatewayService.class); // Specifically, this line
            bindService(serviceIntent, serviceConn, Context.BIND_AUTO_CREATE);
        } else {
            Intent serviceIntent = new Intent(this, MockObdGatewayService.class);
            bindService(serviceIntent, serviceConn, Context.BIND_AUTO_CREATE);
        }
    }
}

解决方案资源管理器的屏幕截图：

黄色突出显示的部分显示该文件确实位于同一项目中，但位于不同的包中，其中红线表示调用试图使用缺少的类的代码的位置

我考虑过这可能是我的清单声明有问题，但我找不到任何错误-我可能错了，所以我将包含一个压缩版本，其中包含以下相关位

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="piccolo.android.PANDA18"
      android:versionCode="1"
      android:versionName="1.0">
        <activity android:name="OBDTaximeter" />

        <activity android:name="obd.ConfigActivity" />

        <service android:enabled="true" android:name="obd.MockObdGatewayService" />
        <service android:enabled="true" android:name="obd.ObdGatewayService" />
    </application>  
</manifest>

为什么会发生这种情况？

像这样开始：

Intent intent = new Intent();
intent.setClassName("obd", "obd.ObdGatewayService");
startService(intent);

您使用的是Multidex还是自定义ProGuard规则？两者都不使用@Bladecoder你能解释一下你的代码和我的启动意图的代码之间的区别吗？我很惊讶这样就避免了这个问题，因为我的所有其他活动都开始使用代码中详述的格式。虽然这是一个解决异常的方法，但它并不能解决当前的问题。
