Buildozer could not find a version that satisfies the requirement threading

Asked 2022-Mar-24 at 18:30

Im trying to build my android app on buildozer but i get this error. I think buildozer can't download or can't find the threading module I researched about the error but couldn't find the solution. Can anyone help me please?

I started the building with "buildozer android debug deploy run" code. I have done this before but it was more simple program.

Edit: I also got same error with "time" module.

ANSWER

Answered 2022-Mar-24 at 18:30

It is because threading is python's standart library. I just deleted threding from buildozer.spec "requirements" section and problem is solved.

Issue using functions from opencv shared libraries cross compiled for android

Asked 2022-Feb-17 at 12:30

I was trying to build and execute a cpp code that links few opencv shared libraries that I had cross compiled for android but while trying to utilize the namespace cv or trying to use a function of opencv, it says undeclared identifier. I did try this documentation here: https://developer.android.com/ndk/guides/prebuilts but was unable to get it working. Also I referred to another stackoverflow question for reference here: OpenCV with Android NDK Undefined References as well. Any guidance on how to link them and import opencv functions properly which I am probably missing out here would be really helpful.

The Problem

Looking at the log, there's not much info, but I can assume from it that you were using WSL or something similar on Windows, not using an actual Ubuntu device. The reason why buildozer doesn't work, I don't know, the log doesn't go far back enough for me to find out, but it is very likely that is because WSL is not a full-fledged Linux distribution

The Solution

The solution for me was to use an online virtual machine called Google Colaboratory

Press cancel to the popup to open a new notebook

Initialize the VM by pressing Connect in the top-right part of the page

Then add a new Code Cell by pressing +Code

To set up buildozer and other commands, paste into the cell and press the play icon

How to get Buildozer to successfully install socket into mobile app via pip

Asked 2021-Jul-25 at 13:10

My issue is that I am unable to create a Python Kivy mobile app using Buildozer without it failing to install one of the dependencies, socket. I have listed socket in the buildozer.spec file, which compiles to the below error. I have also attempted to compile the app without socket as a dependency, which compiles but crashes the mobile app when any socket command is run. How should I go about successfully allowing socket to compile into a buildozer mobile app?

...

ANSWER

Answered 2021-Jul-25 at 13:10

socket is a python builtin module, not something to install via pip.

I have also attempted to compile the app without socket as a dependency, which compiles but crashes the mobile app when any socket command is run

What makes you think the crash is due to missing the socket module?

incompatible target linker error when trying to build Android 64 bit application with Delphi 10.4.2

Asked 2021-Jul-16 at 11:30

I am trying to build a mobile application for Android 64 bit. It works fine for 32 bit, but when trying it for 64 I get this error:

[DCC Error] E2597 C:\Users\Public\Documents\Embarcadero\Studio\21.0\CatalogRepository\AndroidNDK-21-21.0.40680.4203\android-ndk-r21\toolchains\arm-linux-androideabi-4.9\prebuilt\windows-x86_64\bin\arm-linux-androideabi-ld.exe: error: c:\program files (x86)\embarcadero\studio\21.0\lib\Android64\Release\SysInit.o: incompatible target

I get the same error for a few hundred of the .o-files in that directory.

I tried using cleanup and updating the SDK with the SDK Manager manually, but to no avail. This error also occurs when creating a new project.

What can I do fix this? Is there an easy way to do this?

Try removing Android platform from Delphi using Tools -> Manage Platforms and then removing any leftover data from Android SDK manually. Then restart computer and add Android platform to Delphi using Tools -> Manage Platforms.

This should then download, install and configure all necessary Android SDK's that are required by Delphi for Android deployment

OpenCV for Android via Visual Studio to Unity

Asked 2021-Jun-10 at 16:27

I tried to compile a .so library using Visual Studio 2019 along with OpenCV Android in order to use this library in Unity. There are some answers on how to configure Visual Studio to use OpenCV Android (here or here) but none of these work for me. Below you can see my configurations.

Visual Studio 2019 (running on Windows 10)

android-ndk-r21e // also tried with android-ndk-r15c android-ndk-r16b and android-ndk-r17c

OpenCV Android 4.5.2 // also tried with OpenCV Android 4.0.0, 4.0.1 and 4.1.0

My settings in Visual Studio 2019 look as follows:

Configuration Properties

- General

Platform Toolset Clang 5.0 (also tried Clang 3.8 or GCC 4.9)
Configuration Type Dynamic Library (.so)
Target API Level Nougat 7.0 (android-24) (also tried different versions)
Use STL LLVM libc++ static library (c++_static) (also tried "GNU STL static library (gnustl_static)")

C/C++

- General

Additional Include Directories "Path to OpenCV_4_5_2_Android\sdk\native\jni\include"
Code Generation Enable C++ Exceptions "Yes(-fexceptions)"
Language C++17(-std=c++1z)
Precompiled Headers Not using Precompiled Headers

Linker

- General

Additional Library Directories Path to OpenCV_4_5_2_Android\sdk\native\libs\armeabi-v7a

- Input

Additional Dependencies Path to OpenCV_4_5_2_Android\sdk\native\libs\armeabi-v7a\libopencv_java4.so

My Source.cpp I try to compile is just a single function for testing purposes

ANSWER

Answered 2021-Jun-10 at 16:27

I had the exact same issue as you (though I used c++ 11) with the exact same setup, and struggled for days. I believe the errors you're seeing (like me) are from arm_neon.h. Very oddly, I was able to just build (not run) the .so successfully, even with those errors (I say "errors" because if you look at arm_neon.h, others pop up), so try it. Maybe it's some kind of IntelliJ/Intellisense mistake more than anything else where it's catching false negatives from some other toolchain setup.

At the same time, I'm not 100% sure I was always able to build with that issue, so try these steps as well if you can't:

use OpenCV 4.0.1 with Android NDK 16rb. The NDK matters when it comes to OpenCV builds, and this is the only supposed match that I know of.
follow this tutorial from scratch: https://amin-ahmadi.com/2019/06/03/how-to-use-opencv-in-unity-for-android/
if the downloaded OpenCV android SDK is still giving trouble, build OpenCV from the source using his other tutorial here: https://amin-ahmadi.com/2019/02/03/how-to-build-opencv-4-x-for-native-android-development/ and then repeat step 2.

MAJOR EDIT: OpenCV 4.5.2 needs to be treated differently because it no longer uses toolchains with gnu c++. -When you build OpenCV from CMake, build with Android NDK 21e, and do not use the toolchain in OpenCV 4.5.2. Use the one inside the Android NDK's build folder (android-ndk-r21e\build\cmake). -When you build your .so from Visual Studio 2019, do not use the GNU STL, use the LLVM. GNU c++ is no longer part of Android NDKs, and you need to cut it out of the process entirely. -In the Linker Input, put the names of your library files (or file, if it's just the world one) in the Library Dependencies field, not the Additional Dependencies field. -Everything else is the same as in those common tutorials.
