Updated build docs w.r.t. Android and binary sizes
Added hint to read docs/INSTALL too.
curl has been built on many Android versions
Added LOCAL_MODULE_TAGS to support Android gingerbread
Removed types.h from Android makefile
Fixed typo in Android configure command
Rename CURL_SOURCES macro; revert previous rename of curl_SOURCES macro.
Improved the Android build instructions
Copy the license file so it's seen by the Android build system
Provide instructions on creating curl_config.h
Copy the libcurl header files into the right location for Android.
renamed generated config.h to curl_config.h in order to avoid clashes…
… when libcurl is used with other projects which also have a config.h.
Created a basic Android make file for curl and libcurl. A config.h
is also needed before curl can be built in Android, but it's not clear
what the best way is to provide one.
