基本上，当用户上传一个 .apk 文件时，我需要解码它并从 apk 内部的 AndroidManifest.xml 文件中提取一些信息。当我在命令行中运行以下命令
然而，如果我尝试使用php的
apktool decode BluetoothChat.apk 一切都很顺利。输出结果如下：I: Baksmaling...
I: Loading resource table...
I: Loaded.
I: Loading resource table from file: /home/tashax/apktool/framework/1.apk
I: Loaded.
I: Decoding file-resources...
I: Decoding values*/* XMLs...
I: Done.
I: Copying assets and libs...
然而，如果我尝试使用php的
exec()函数从webcode执行它，就会出现错误。它在I: Loading resource table from file: /home/tashax/apktool/framework/1.apk处失败，我认为它找不到framework/1.apk文件。这似乎是设置问题，有人做过类似的事情或知道我缺少什么吗？以下是从网页运行apktool时的错误：I: Baksmaling...
I: Loading resource table...
I: Loaded.
