Fixes ndk url in current buildozer #778 #760 #767 — committed to guysoft/buildozer by guysoft 5 years ago

Looks like the NDK download URL has been a bit of a moving target.

two ways I was able to resolve this:

option 1) to get buildozer to perform the download for you by correcting the download URL: <PYTHON_INSTALL_DIR>/site_packages/buildozer/targets/android.py line 316 change the url from /repository/ to /ndk/ then rerun buildozer as normal and it detects that the NDK is missing and downloads it from the correct URL.

option 2) do the download by hand per codingsett’s comment, but make sure you have the version that buildozer expects. In my case it wants r9c. So download http://dl.google.com/android/ndk/android-ndk-r9c-linux-x86_64.tar.bz2, and unzip it into the expected location, in this case ~/.buildozer/android/platform then run buildozer again as normal.

clear old buildozer files $rm -rf .buildozer uninstall latest version $pip uninstall buildozer cython install old stable version $pip install buildozer==0.34, cython==0.25.2 initialize buildozer and sdk $buildozer init && buildozer android adb -- version again remove .buildozer and upgrade to latest version $rm -rf .buildozer $pip install buildozer==0.37, cython==0.28.5 --upgrade use

Download ndk manually then paste it in /home/deax/.buildozer/android/platform/ it should fix that error

Had the same issue. Turns out it was my proxy setting that caused trouble when downloading files, i.e. I removed http_proxy and https_proxy and then it worked. Hope, that helps.

If anyone have difficulties to finding this: python -m site --user-site or python3 -m site --user-site
