我想用不同的选项(例如免费和付费版本)多次编译我的Android应用程序,而无需手动执行某些操作.
自动执行此操作非常重要.像图书馆这样的所有解决方案都无济于事,因为有几件事需要手工完成.

下面将对步骤进行示例调用.

>使用不同的包名称打包应用程序：

aapt package -f -M ./AndroidManifest.xml -S res/ \
    -I android.jar -F renamed_project.apk.unaligned \
    --rename-manifest-package "com.example.some_new_package" -v

>然后添加类：

aapt add -f renamed_project.apk.unaligned classes.dex -v

>签名：

jarsigner -verbose -sigalg MD5withRSA -digestalg SHA1 \
    -keystore "some_keystore_file" \ 
    renamed_project.apk.unaligned "key_name"

>对齐它：

zipalign -v 4 renamed_project.apk.unaligned renamed_project.apk

可以找到更多信息,例如here.

您也可以使用Ant更轻松地完成此操作. Here您可以找到更多信息.

An unnamed namespace or a namespace declared directly or indirectly
within an unnamed namespace has internal linkage. All other namespaces
have external linkage. A name having namespace scope that has not been
given internal linkage above has the same linkage as the enclosing
namespace if it is the name of …

“在另一个命名空间之间间接声明一个命名空间”是什么意思？

现在,我正在尝试编译我的第一个示例程序：

1 #include <iostream>
  2 #include <tins/tins.h>
  3 
  4 using namespace Tins;
  5 
  6 bool callback(const PDU &pdu) {
  7     const IP &ip = pdu.rfind_pdu<IP>(); // Find the IP layer
  8     const TCP &tcp = pdu.rfind_pdu<TCP>(); // Find the TCP layer
  9     std::cout << ip.src_addr() << ':' << tcp.sport() << " -> "
 10               << ip.dst_addr() << ':' << tcp.dport() << std::endl;
 11     return true;
 12 }
 13 
 14 int main() {
 15     Sniffer("eth0").sniff_loop(callback);
 16 }

当我想编译它时,我面临以下错误：

怎么了？
