我的应用程序模块正在同一个项目中为各种类使用库模块。 Android Studio中没有显示错误，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一个类时，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>
在我的主要申请中：
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);
}
logcat的

答案 0 :(得分：0)
问题通过添加：
解决Bundle data = msg.getData();
data.setClassLoader(IDevice.class.getClassLoader());
