AndroidBuild
Android 多渠道打包方案 中已经介绍了基本的思路和基本的源代码,这里给出实践过程出现的问题和解决思路。
首先如果你没有使用上篇博客中给出的Python脚本,而是自己写了shell脚本或者其他脚本,如果实现思路如下:
那么可能出现下面类似的问题:

注意L2 行,问题在这里,看看前面一个代码栈,GifDrawable是第三方支持动态图的类库,所以溯本逐源到GifDrawable.java

* Basic GIF metadata can also be examined.

继续追踪openRawResourceFd()方法

很明显不支持gif,所以通过上面的解压缩和压缩,就很可能导致一些资源文件不能识别,所以尽量避免解压缩和压缩apk,而应该像Python脚本给的那样,直接向压缩包写入文件,避免不必要的麻烦。
# zip获取新建立的apk文件
zipped = zipfile.ZipFile(target_apk, 'a', zipfile.ZIP_DEFLATED)
# 初始化渠道信息
empty_channel_file = "META-INF/xxxx_{channel}".format(channel = target_channel)
# 写入渠道信息
zipped.write(src_empty_file, empty_channel_file)
