I have created a simple project with 3 buttons and some texts. I have added AdMob (for testing) and installed Android Build Template in the project folder, and exported the project using Gradle setting. And the resulting size is 125 MB!!! I have searched for solutions in internet and tried inserting custom.py with the following code into the project root:
custom.py
tools=no
deprecated=no
minizip=no
xml=no
builtin_glew=no
builtin_libmpcdec=no
disable_3d=yes
disable_advanced_gui=yes
builtin_openssl=no
module_openssl_enabled=no
builtin_libogg=no
builtin_libtheora=no
builtin_libvorbis=no
builtin_opus=no
builtin_speex=no
builtin_squish=no
builtin_zlib=no
module_chibi_enabled=no
module_cscript_enabled=no
module_dds_enabled=no
module_etc1_enabled=no
module_gridmap_enabled=no
module_ik_enabled=no
module_jpg_enabled=no
module_mpc_enabled=no
module_ogg_enabled=no
module_opus_enabled=no
module_pbm_enabled=no
module_pvr_enabled=no
module_speex_enabled=no
module_squish_enabled=no
module_theora_enabled=no
module_vorbis_enabled=no
However, this did not help. I would appreciate any advice. I want to reduce the size to 10-15 MB, if possible.
