Android-libcurl porting, compilation and Testing

1. Port the Curl tool to the Android 2.3 environment step 1. Download the curl Source Code directly to the website. 2. Use tar in the android compiling environment, usually put in the external directory 3. Because Curl depends on some header files and definitions, You need to first execute the configuration file and compile curl under external/curl. sh requires cd external/curl /. curl. sh, or put it in the android root directory *. sh Script: source external/curl. sh: The CURL path, compilation tool chain path, and other variables [cpp] #!
