Is your code python 3?

[mostwanted]

No its python 2

Hey @Geo, I see you were able to create an APK file (https://groups.google.com/forum/#!topic/kivy-users/HMr2NP8Gcuk) How were you able to achieve that? I am stuck and its sad and cold over here, please save me!

So problem occurs in building libffi 





STDOUT:
/home/mostwanted/Desktop/app1/.buildozer/android/platform/build/build/other_builds/libffi/armeabi-v7a__ndk_target_21/libffi/autogen.sh: 2: exec: autoreconf: not found

So problem is : autoreconf: not found




Looking at the libffi recipe


https://github.com/kivy/python-for-android/blob/master/pythonforandroid/recipes/libffi/__init__.py

We see

Requires additional system dependencies on Ubuntu:
 - `automake` for the `aclocal` binary
 - `autoconf` for the `autoreconf` binary

Is autoconf installed ?

The way to debug this stuff is to learn to read every line of the log file, and wonder what could that mean?

[mostwanted]

I figured that there were a couple of packages i was missing, i installed autoreconf and a couple of others and i was able to create my APK file finally thanks to Robert for encourage me to ponder over my Traceback. But now i am facing a problem with APK file after installing on my phone, when i click on it to istall i get an error called Parse Error (There was a problem while parsing the package),  what could be causing this???

I have no clue!

But your friend Google has lots of suggestions to this search "parse error there was a problem while parsing the package"

For example:

https://stackoverflow.com/questions/1492401/parse-error-there-is-a-problem-parsing-the-package-while-installing-android

Could be all kinds of things, file names, version numbers......

If you have not done so already, try to build and install 'helllo world' with the same build settings.

If there is still a problem, look at the build settings. This will help to put a lower bound on the problem.
