Android: 没有 Class 来自依赖模块的 Def 异常

Question

我的应用程序模块正在为各种类使用同一个项目中的库模块。 Android Studio 中没有显示任何错误，而且当我构建时，我没有任何错误。但是当它试图从库中访问我的类之一时，它会抛出一个 NoClassDef 异常。有谁知道我做错了什么？ Logcat 输出如下。

服务清单（我使用的是自定义 SDK）：

<manifest xmlns:android="http://schemas.android.com/apk/res/android"    
    xmlns:tools="http://schemas.android.com/tools"
    package="com.linear.deviceservice"
    android:versionCode="1"
    android:versionName="1.0"
    android:sharedUserId="android.uid.system" >

    <uses-sdk
        android:minSdkVersion="19"
        android:targetSdkVersion="19" 
        tools:ignore="OldTargetApi" />
    <uses-permission android:name="android.permission.SERIAL_PORT"/>

    <application
        android:allowBackup="true">
        <service 
            android:name="LinearService"
            android:exported="true"
            android:permission="com.project.permission.DEVICE_SERVICE">
            <intent-filter>
                <action android:name="com.project.deviceservice.BIND"/>
            </intent-filter>
        </service>
    </application>

</manifest>

在我的主要应用程序中：

List<PeripheralDevice> devices =
    mConfigurationManager.getConfiguration().getPeripheralDevices();
/* Send the update message with list of appropriate uris to each service. */
ArrayList<Uri> uris;
/* For each service, get the list of uris for that service. */
for (String scheme : mServices.keySet()) {
    uris = new ArrayList<Uri>();
    for (PeripheralDevice device : devices) {
        if (scheme.equals(device.getUri().getScheme())) {
            uris.add(device.getUri());
        }
    }
    /* Send the update message here. */
    updateDevices(mServices.get(scheme), uris);
}

在我的服务中：

protected List<IDevice> mDevices = new ArrayList<IDevice>();
...
{
    mDevices = msg.getData().getParcelableArrayList(Messages.DEVICES_KEY);
}

Answer 1

问题已通过添加解决：

Bundle data = msg.getData();
data.setClassLoader(IDevice.class.getClassLoader());

Android: 没有 Class 来自依赖模块的 Def 异常
