This problem has several solutions, and I tried each of them, and the latter worked correctly. I give you the exact steps that I have taken to make it work for me.
1. Check if Cygwin has the necessary packages if they are not installed. The following packages are required -
autoconf, automake, binutils, gcc-core, gcc-g++, gcc4-core, gcc4-g++, gdb, pcre, pcre-devel, gawk, make
(I skipped gcc4-core and gcc4-g ++)
2. Marker Felt.ttf, , C: .
3. Eclipse .
4. , . Asset build_native.sh. build_native.sh( )
chmod 777 -R "$APP_ANDROID_ROOT"/assets
