No valid --ndk-api received, using the default of 0 = min(android-api=0, default ndk-api=21)

[bunmalik]

I read this was reported as a bug in the older version and there has been a fix here (kivy/python-for-android#1381 (comment)). But it seems like the bug still persists. Please come to my aid, perhaps there is something wrong I am doing which I might not know.

Versions

• Python: 2.7
• OS: Ubuntu 16.04
• Kivy: 1.10.1
• Cython: 0.27.3
• buildozer: 0.37

Description

Buildozer was not able to build apk.

Command:
buildozer -v android debug

Spec file:

   # (int) Android API to use
    android.api = 28

   # (int) Minimum API required
    android.minapi = 21

    # (int) Android SDK version to use

@bunmalik It's a holiday time, afaik a lot of people are generally "away". Please come to https://chat.kivy.org to make sure someone notices your issue or better said someone who already solved it can help you.

Personally, I've had no such problem, but I use master branch of python-for-android. Please try to upgrade p4a to the development version (master) and give it another try. :)

Maybe try setting android.ndk_api

buildozer/buildozer/default.spec

Line 103 in c4c632f

#android.ndk_api = 19

[bunmalik]

@SomberNight, I did as u said, it only sent away the [WARNING]: No valid --ndk-api received, using the default of 0 = min(android-api=0, default ndk-api=21) and repeated the same error in my Logs...

@KeyWeeUsr, thanks for the link but the python-for-android suggestion did not work.I set p4a.branch = master in my .spec file ...please I need help to resolve dis issue. I have searched the internet severally and this has kept me stacked almost a month now....

No one here to address this issue

I have same issue please help us

I think 17c is the highest supported ndk. have you tried that with kivy and p4a master?

This is a problem qhe struggles me everytime, and time to time while things get updated over the time. But I solve it in the same way always.

Sometimes, the sdk gets updated and your old settings doesn't work anymore, sometimes only certain versions of sdk/ndk works togheter.

Remove/comment all your ndk/sdk paths and use the android.sdk/ndk settings to re-download them by buildozer untill someone works.

Despite the comments about recommended versions in the logs. For me, the android.minapi = 21 is the only one that works out of the box. The same settings with 19 will fail with logs like "check wheter the gcc compiler works = no" that lends you to think that you need to install any gcc.

The gcc (the toolchain for arm) is on the ndk, and if it fails means that you're using the wrong set of choice for sdk/ndk.

Just keep triying versions untill it works. If you had specified many settings, less is more, start with just android.minapi and tune settings to your needs one by one.

Regards.
