Question

将应用程序上传到Worklight Application Center时，我在message.log中收到以下错误：

"com.ibm.puremeap.resources.desktop.UploadService W JSON error when trying to upload file IBMApplicationCenter.apk"

此外，在trace.log中，整个堆栈跟踪如下：

有谁能告诉我如何解决这个问题？顺便说一句，我成功地尝试在worklight控制台中部署wlapp和适配器。

我的环境是：

- RHEL v6.x 64 bit
- Worklight v5.0.6
- DB2 10.x

我做了进一步的调查：

在Win7 64位上使用Worklight Server并连接到同一个数据库实例。一切都很好。此外，我浏览了在Linux环境中运行的应用程序中心。 appcenter在Win7上传的应用程序没有问题。
从两个envs（RHEL 6和Win7）检查trace.log中的pkg值。结果不同。

在Win7的trace.log上：

[2013/4/11   10:48:18:944 TST] 00000040 id=         ApplicationService                                           > __create__ ENTRY {0} {1} {2}

在RHEL 6的trace.log上：

[4/11/13 11:44:48:694 CST] 00000308 id=         ApplicationService                                           > __create__ ENTRY {0} {1} {2}

Answer 1

您尝试将APK上传到Worklight Application Center时发生错误。在此步骤中，APK将被分析。 RHEL跟踪日志表明不仅缺少pkg（null），而且APK大小为null。这可能表明APK是非常错误的。

第一步是验证APK是否正确。为此，只需将其解压缩（APK是一个zip文件），并验证它是否包含AndroidManifest.xml。该文件是二进制文件，pkg值将来自那里。如果它丢失了，这是致命的。

接下来，验证可以通过aapt（位于平台工具中的Android SDK中）分析APK：

aapt dump badging somefile.apk

您似乎尝试上传IBMApplicationCenter.apk，因此在您的具体情况下，它是：

aapt dump badging IBMApplicationCenter.apk

这会输出几行，通常以

之类的行开头

package: name='com.ibm.appcenter' versionCode='1' versionName='1.0'

这是pkg值的来源。如果这不起作用，则Worklight Application Center无法找到pkg，或者Android Manifest无效。

在APK上传机制期间，会发生以下情况：

如果在服务器配置文件中设置了属性android.aapt或android.aapt.dir（对于Liberty的bootstrap.properties，对于Tomcat的catalina.properties或对于WAS的Java VM属性），那么将在该位置和“aapt dump badging”如前所述执行，输出由Worklight Application Center分析。这可以解释为什么你在Win7和RHEL上看到不同的行为，因为你在那里有不同的执行执行。
如果没有设置android.aapt或android.aapt.dir属性，则Worklight应用程序中心不会使用aapt但会尝试解码APK本身。因此，您可以尝试取消设置服务器中的android.aapt属性并重新启动服务器，以检查是否可以解决问题。
