kivy app crashing on launch

[dessant]

From @Terrydaktal on January 2, 2017 0:30

after advice from issue #4864
-i have rebuilt python-for-android and buildozer from the repo
-i have changed buildozer.spec to include all modules imported into python: buildozer.spec.txt
-i have used android_new and built an apk with that, and another apk with just android as well

both applications however still crash, the error produced when using only 'android' to compile, is overcome when using android_new and using python2 in the requirements, however the error now is such: i will provide the full logcat:
particularly looking at that specified child already has a parent error, this is an error i got before when using android_new, i looked up solutions at the time, but none helped me, the suggestions were to make sure everything is up to date, but everything is

Looks like your error has nothing to do with the Window; but rather a bad import; see here:

01-02 00:12:59.853 26524 26551 I python : ImportError: dlopen failed: "/data/data/org.test.myapp/files/app/_applibs/numpy/core/multiarray.so" not 32-bit: 2

@FeralBytes, after removing multiarray.so, the import error no longer appears, the removeview error remains however, the app still crashes

[dessant]

From @FeralBytes on January 6, 2017 4:7

That error may have something to do with the Splash screen; if I am reading the Java exception correctly; can you try again from Kivy latest via github and ensure the error still occurs. Also can you share a slimed down version of your code that crashes?

@FeralBytes I have tried it with latest kivy, latest buildozer, I have switched round the buildozer.spec so many times but the.apk still crashes on launch with that error.

It's not a very long code so here :

From @Terrydaktal on January 7, 2017 22:53

If someone could get a working apk out of this I would really appreciate it.

[dessant]

From @FeralBytes on January 16, 2017 10:43

@Terrydaktal please post a new log output now that you have removed the "multiarray.so".

[dessant]

This looks like either an user error, or an issue with the numpy recipe, moving to p4a.

[Terrydaktal]

@dessant IIRC the log was exactly the same but with the multiarray.so mention gone. When I get home later I'm going to try and compile the apk on a new machine, and see if it works then.

[FeralBytes]

needs awaiting reply tag
@Terrydaktal how did the compile go?

[Terrydaktal]

Still the same error on the new machine, this simply does not compile with any ndk or any sdk version for Android api 19, it crashes with that same error on launch

[FeralBytes]

@Terrydaktal still need that new log verbatim copied to github; the one without the multiarray.so so that we can look through it.
If it makes you feel any better; I too am not able to get any apps working right now.

[Terrydaktal]

I don't think removing multiarray.so is the best solution, I think any consequent issues that will arise will be because of multiarray.so being missing, as opposed to multiarray.so being present but' not 32 bit',

When opening the original app built for api 19, ndk r13b, Android new, sdk 25.2 I think it is, on another phone with Android 6 the same error is produced before multiarray.so is removed.

As you can see the removeView error remains
My next step is to remove multiarray from the app on the Android 6 device as that is the only traceback that is produced, I wonder what error it would then give.

[FeralBytes]

Are you building in debug mode or release mode because it seems like there should be more output than just this.
Just for reference we are fighting similar issues but the output from our programs seems to be a little bit more verbose; the issue is here for reference: #992

[Terrydaktal]

sudo buildozer android_new debug serve is the exact command I use
