Kivy Buildozer VM sh.ErrorReturnCode_127 error

Question

I am trying to build a simple Python program to an APK with Buildozer on the Kivy Virtual Machine. Every time I run buildozer android debug, I get the following error

pid 2134:

Note: my log_level in my buildozer.spec is 2. I have tried to install some dependencies, but the Kivy VM does not let me for whatever reason. If anyone could help me out, that would be great!

Answer 1

I had the same issue and in my case i was missing the following system dependencies that are require for python-for-android as described in the file:python-for-android file

The dependencies i was missing:

• automake
• autoconf
• libltdl-dev

I found that solution in the Github forum of Buildozer: Github Question

So you are probably missing some dependencies as well. For me running the following commands worked perfectly:

sudo apt-get install automake
sudo apt-get install autoconf
sudo apt-get install libltdl-dev
