U8SDK——区分参数存储的位置(assets目录中还是AndroidManifest.xml中)

作者: U8技术团队分类: U8SDK 发布时间: 2015-02-28 20:05 64条评论

最近有同学在使用U8SDK接入360SDK的时候,发现了一个问题。就是360渠道SDK需要的APPID等参数是需要放在AndroidManifest.xml中的。而
u8sdk里面，则是把这些参数放在各个渠道SDK配置目录下的config.xml中，然后打包工具在打包的时候，会将这些信息统一地写入到assets目录下的
develop_config.properties文件中。

现在这个问题，也很好解决。我们在config.xml中配置params的时候，我们在每个param里面增加两个属性。bWriteInManifest和bWriteInClient

如果bWriteInManifest=1,打包的时候，打包工具就将该参数添加到AndroidManifest.xml的meta-data里面。

如果bWriteInClient=1，或者你不配置，默认情况就将该参数添加到develop_config.properties文件中。

（注：新版U8SDK已经支持了）

那么对于已经在使用u8sdk的童鞋们，可以按照如下步骤来添加对应的支持。同时，顺便也熟悉了解下打包脚本的原理吧。

首先在config_utils.py里面loadChannelUserConfig这个方法里,将下面这段代码:

     paramNodes = configNode.find("params")
     if paramNodes != None and len(paramNodes) > 0:
          channel['params'] = []
          for paramNode in paramNodes:
               param = {}
               param['name'] = paramNode.get('name')
               param['value'] = paramNode.get('value')

               channel['params'].append(param)

paramNodes = configNode.find("params")

if paramNodes != None and len(paramNodes) > 0:

channel['params'] = []

for paramNode in paramNodes:

param = {}

param['name'] = paramNode.get('name')

param['value'] = paramNode.get('value')

channel['params'].append(param)

修改为如下格式，增加bWriteInManifest和bWriteInClient参数的解析。

     paramNodes = configNode.find("params")
     if paramNodes != None and len(paramNodes) > 0:
          channel['params'] = []
          for paramNode in paramNodes:
               param = {}
               param['name'] = paramNode.get('name')
               param['value'] = paramNode.get('value')

               writeInManifest = paramNode.get('bWriteInManifest')
               writeInClient = paramNode.get('bWriteInClient')

               if writeInClient == None and writeInManifest == None:
                    writeInClient = '1'
                    writeInManifest = '0'

               if writeInManifest == None:
                    writeInManifest = '0'

               if writeInClient == None and writeInManifest != '1':
                    writeInClient = '1'

               param['bWriteInManifest'] = writeInManifest
               param['bWriteInClient'] = writeInClient         

               channel['params'].append(param)

paramNodes = configNode.find("params")

if paramNodes != None and len(paramNodes) > 0:

channel['params'] = []

for paramNode in paramNodes:

param = {}

param['name'] = paramNode.get('name')

param['value'] = paramNode.get('value')

writeInManifest = paramNode.get('bWriteInManifest')

writeInClient = paramNode.get('bWriteInClient')

if writeInClient == None and writeInManifest == None:

writeInClient = '1'

writeInManifest = '0'

if writeInManifest == None:

writeInManifest = '0'

if writeInClient == None and writeInManifest != '1':

writeInClient = '1'

param['bWriteInManifest'] = writeInManifest

param['bWriteInClient'] = writeInClient

channel['params'].append(param)

这样，就将config.xml里面param配置里面的bWriteInManifest和bWriteInClient属性解析出来了。解析完了，还不行。我们需要根据这两个属性将
该参数分别填写到develop_config.properties和AndroidManifest.xml里面

首先，我们需要在config_utils.py里的writeDeveloperProperties里面将写入develop_config里的参数给过滤下.将原来的代码片段：

     if channel['params'] != None and len(channel['params']) > 0:
          for param in channel['params']:
               proStr = proStr + param['name'] + "=" + param['value'] + "\n"
          file_utils.printF("The developInfo is "+proStr)

if channel['params'] != None and len(channel['params']) > 0:

for param in channel['params']:

proStr = proStr + param['name'] + "=" + param['value'] + "\n"

file_utils.printF("The developInfo is "+proStr)

修改为：

     if channel['params'] != None and len(channel['params']) > 0:
          for param in channel['params']:
               if param['bWriteInClient'] == '1':
                    proStr = proStr + param['name'] + "=" + param['value'] + "\n"
          file_utils.printF("The developInfo is "+proStr)

if channel['params'] != None and len(channel['params']) > 0:

for param in channel['params']:

if param['bWriteInClient'] == '1':

proStr = proStr + param['name'] + "=" + param['value'] + "\n"

file_utils.printF("The developInfo is "+proStr)

这样，只有config.xml里面bWriteInClient=1的那些参数才会被写入到develop_config.properties.里面

紧接着，我们还需要将那些bWriteInManifest=1的参数添加到AndroidMananifest.xml中。我们需要在apk_utils.py增加一个方法，拷贝到文件最后面即可。

def writeManifestMetaInfo(channel, decDir):
     manifestFile = decDir + "/AndroidManifest.xml"
     manifestFile = file_utils.getFullPath(manifestFile)
     ET.register_namespace('android', androidNS)
     tree = ET.parse(manifestFile)
     root = tree.getroot()

     key = '{'+androidNS+'}name'
     val = '{'+androidNS+'}value'

     appNode = root.find('application')
     if appNode is None:
          return

     metaDataList = appNode.findall('meta-data')

     if metaDataList != None:
          for metaDataNode in metaDataList:
               keyName = metaDataNode.attrib[key]
               for child in channel['params']:
                    if keyName == child['name'] and child['bWriteInManifest'] == '1':
                         file_utils.printF("The meta-data node repeated. "+keyName)
                         metaDataList.remove(metaDataNode)


     for child in channel['params']:
          if child['bWriteInManifest'] != None and child['bWriteInManifest'] == '1':
               metaNode = SubElement(appNode, 'meta-data')
               metaNode.set(key, child['name'])
               metaNode.set(val, child['value'])

     tree.write(manifestFile, 'UTF-8')

     file_utils.printF("The manifestFile meta-data write successfully")

def writeManifestMetaInfo(channel, decDir):

manifestFile = decDir + "/AndroidManifest.xml"

manifestFile = file_utils.getFullPath(manifestFile)

ET.register_namespace('android', androidNS)

tree = ET.parse(manifestFile)

root = tree.getroot()

key = '{'+androidNS+'}name'

val = '{'+androidNS+'}value'

appNode = root.find('application')

if appNode is None:

return

metaDataList = appNode.findall('meta-data')

if metaDataList != None:

for metaDataNode in metaDataList:

keyName = metaDataNode.attrib[key]

for child in channel['params']:

if keyName == child['name'] and child['bWriteInManifest'] == '1':

file_utils.printF("The meta-data node repeated. "+keyName)

metaDataList.remove(metaDataNode)

for child in channel['params']:

if child['bWriteInManifest'] != None and child['bWriteInManifest'] == '1':

metaNode = SubElement(appNode, 'meta-data')

metaNode.set(key, child['name'])

metaNode.set(val, child['value'])

tree.write(manifestFile, 'UTF-8')

file_utils.printF("The manifestFile meta-data write successfully")

这个方法就是将所有bWriteInManifest=1的参数添加到AndroidManifest.xml中的meta-data中。

然后，在main.py里面的doPack方法中，在apk_utils.writeSupportInfo(channel, decDir)行的下面一行，添加writeManifestMetaInfo的调用。
添加后，这块代码像这样：

     apk_utils.writeDevelopInfo(channel, decDir)
     apk_utils.writeSupportInfo(channel, decDir)
     apk_utils.writeManifestMetaInfo(channel, decDir)

apk_utils.writeDevelopInfo(channel, decDir)

apk_utils.writeSupportInfo(channel, decDir)

apk_utils.writeManifestMetaInfo(channel, decDir)

最后，为了验证是否有些参数可以被添加到AndroidManifest.xml中。你修改下main.py里面doPack方法，注释掉file_utils.del_file_folder(workDir)。

然后，执行pack_debug.bat打包工具，打包完成后，在u8work/渠道名称/decompile/目录下，打开AndroidManifest.xml文件，看看里面是否有你需要添加的参数。同时，看decompile目录下面assets目录下面develop_config.properties里面的属性是否也正确。
