i wrote a code in python that uses all of these modules: kivy, nba_api,datetime,python-dateutil i was trying to add all of these to the requirements section in the spec file to create the apk but there is a problem with the nba _pi mudle i think it's not supported by python-for-android is there a way to fix this issue/make this work? (please help it took me a long time writing this code and it will be very frustrating if it was all a waste of time).
i tried crating the apk but every time i open it it crashes i wrote a second code to test all of the other modules they work fine it's the nba_api that causing the issue anyone know how to fix it?

I created a mobile application using kivy, but after having it installed on android device, it does not launch. Below is the buildozer.spec file.
title=Translator
package.domain=org.test
source.dir=.
source.include_exts = py,png,jpg,kv,atlas
version=0.1
requirements=python3,kivy,requests,bs4 #I used requests and bs4 libraries for webscraping purposes, I'm not completely sure that I do not need any other requirements for internet connection.
orientation=all
osx.python_version=3
osx.kivy_version=2.0.0
fullscreen=0
android.arch=arm64-v8a
android.allow_backup=True
#then some ios speceific settings which I think are not important as my device is android.
[buildozer]
log_level=2
warn_on_root = 1
I created the apk file, installed it on my android device, but when I click on it, it just does not launch. I dont really understand why, I was thinking that I didn't pass requirements that enable the app to use internet connection, or that it does not launch because of my phone settings. How can I solve this issue? Any help is appreciated a lot.
UPDATE
I actually tried to install another python/kivy program on android phone not involved with web scraping, and it worked. So I guess I put wrong wrong requirements in the buildozer.spec. But I wonder if there are some requirements that MUST be included besides the module names that are used to build the app. Any help?
UPDATE ON UPDATE
I found this line in the buildozer.spec file:
#android.permissions = INTERNET
and I put that line out of comment. But still that did not help any way. After installing the app on my phone, it just won't launch. Now I have no idea what I can do to solve this issue. Any ideas or advices?
I have a simple calculator app. It's a complete application all by itself.
I also have a more advanced calculator app that's based on the first app, but has more features. Its main Activity extends the first app's main Activity. The advanced app references quite a lot of resources and methods from the simpler app.
Getting the advanced app to build under Android Studio has been a nightmare. I've been googling and trying things blindly in the build.gradle files, but not making much progress. At first, the problem was dependent features configured but no package id was set (whatever that means, Google turned up no documentation.)
I got past that by tweaking the build.gradle files, and now I'm getting Manifest merger failed with multiple errors, see logs, but I can't find the relevant logs. It looks like the build failed because Android Studio tried to merge the AndroidManifest.xml files from the simple app and the advanced app, but I just wanted to use the manifest from the advanced app.
This is all very frustrating because I made it all work under Eclipse but now I have to move to Android Studio.
I guess my first question is: How can I tell Android Studio to just use the Android Manifest from the current project and not try to merge from the other project.
In general: can an application project serve as a library for another project, and if so how? Are there any examples?
Third question: where can I find good documentation on build.gradle?
I could attach my current build.gradle files and AndroidManifest.xml files if people need to see them, but I'm really hoping to learn enough that I can help myself.

Lately, while attempting to build an interesting open source android-web streamer: Android-Eye, I noticed that several people, including myself have been stumped by process of building the application given that it contains c/c++ code that (I think) needs to be compiled by the android ndk before anything can work. The fact that the dev doesn't seem to be active anymore doesn't make this any easier.
I've been trying to get this to work for well over 3 days now and can say with full confidence that I do not posses the knowledge (especially for the ndk) to get this thing built. The long list of things i've tried is too extensive to be covered in this post but here are a few git issues posted by others that have experienced similar issues as me:
https://github.com/Teaonly/android-eye/issues/32
https://github.com/Teaonly/android-eye/issues/27
I understand that it may look as if I am asking to be "spoonfed" the process of building the application but a few pushes in the right direction would be excellent :)
BTW, I have access to windows and mac boxes incase that influences the build process.
Thanks
Background
I wanted to simplify the usage of DB in an Android app.
For this, I've compared some third party libraries that create a DAO layer.
I've come up with a nice library called "GreenDao" (presentation about it here) . The website shows that it's faster than other competitors (like ORMLite) and is optimized for Android.
The problem
For some reason, on some device (usually old devices, with GB) , I get the next console error when trying to install the app:
Installation error: INSTALL_FAILED_DEXOPT
Please check logcat output for more details.
Launch canceled!
I've searched for the reason of this error, but couldn't find out how to solve it. Many complain about this error, but I can't find out why it occurs, and what can be done.
The error is quite common and known, but it's never mentioned as the result of using this library, yet when I remove the usage of this library, everything works fine...
Also note that on newer devices (like nexus 4) it installs and works just fine, and that the sample itself also works fine no matter which device I test it on.
The question
Why does it occur?
Is it possible that the structure of the classes is just too much for old devices to load, since we use other libraries ?
Could it be that I've reached the limit of code that is supported by android apps?
The jar file itself takes just 87KB ...
How can I solve this?
Ok, I've found the problem and the solution:
It has nothing to do with GreenDao.
It's because the app uses too many jars, so maybe Android has a limitation of code.
The solution is to either delete un-needed jar files or delete a lot of code.
I have a project template , when i want to produce a unique application manually to update it to the market. I will follow these steps :
Right click in the package name
Refactor, then Rename
Renaming the package in minifest then update the version code
finally to clean the code from imports errors such as *.R; errors
My question is there any tool that automate this refactoring process without being involved on it ?
i tried to create a java tool but it consumes memory and some things i have to finalize it manually , i'm searching for this since 3 days and nothings gives you a clear answer.

The new Gradle-based build system can handle this scenario. In fact, it allows you to separate the package name used by R.java (to keep it consistent) and the package name used for determining whether the app is unique on the device and in the Play Store.
I recommend that you watch "The New Android SDK Build System" video from the Google I|O 2013 conference to learn more about what it can do, as Xav definitely covers this scenario.
Note that while it is not a "right click", it should make scripting a solution fairly easy.
Thank you all, I've solved this problem by converting the template project into JAR and let another small project handle every thing , I've created a small method that updates the minifest in that small project and i had to update package,ver name and ver code ONLY ,then I've generated the APK using ANT ,however i tested the project and it works fine , hope this will help another people
