QUESTION
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 16:27I 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.

I just want to set android emulator without studio-ide and use it like a mobile and tweak it.
I have downloaded command-line tools from https://dl.google.com/android/repository/commandlinetools-linux-6858069_latest.zip

Answered 2021-May-16 at 15:03I am answering my own question.
Where I made wrong is, decompressing to wrong directory and using wrong --sdk_root.
As said in here, I have to create a dir called cmdline-tools
and decompress in it. Now we will have another cmdline-tools dir. We have to rename it to the respective commandline tool version we are using. In my case it is 3.0.
Finally my script should be look like below.

QUESTION
As per the tittle, I am unable to get the EGL14.eglGetCurrentContext()
inside an Android Java class. More precisely, the returned context is equal to EGL14.EGL_NO_CONTEXT
.
My interpretation is that the code is called from the main Unity thread yet the code is not able to get the OpenGL context.
Multithreaded rendering is disabled. The project is a Unity project exported to Android. This C# code calls the Java initSurface
method from an Update
function of a MonoBehavior

Answered 2021-Apr-13 at 11:18It was occurring because Unity was using Vulkan instead of OpenGLES all along. Disabling the Automatic Graphics API in the Player settings and dragging OpenGLES2 on top fixes the issue.

Here is the same code on both emulators side-by-side. Local time is 16:37
, GMT time is 11:07
at the time of this screenshot. Both emulators are already set to the same timezone as the system.

QUESTION
Using the w3schools.com SQL tutorial Northwind database, I'm trying to display the category that has the most products shipped. Additionally, I want to display the net income from all sales in that category. I can't figure out how to take the category with the most products shipped, and use the amount of products shipped to calculate the net income of that category. This is because there are many different products that have the same CategoryID but different prices.
...ANSWER
Answered 2021-Jan-25 at 07:24So first of all you get the income for each product and category and then based on that you find total income for that category and you do this with the help of subquery, then you join this resultant table with the category table and with the help of group by you find the product count and total income for each category, below is the sql query for more indepth understanding

...ANSWER
Answered 2021-Jan-29 at 10:56Your network config there is within , which only applies for debug builds. Did you build the application in debug mode, or for production? If you don't build in debug mode then that config won't apply.
You probably want to use instead, which applies to all builds, not just debug builds. There's a full example here: https://httptoolkit.tech/docs/guides/android/#if-you-dont-have-a-custom-network-security-config.
If that doesn't work, then it's likely that there's some certificate pinning in place in the application code itself, independent of the network security settings. To fix that you'll need to manually edit the code itself. You can also try using https://github.com/shroudedcode/apk-mitm which has a selection of automated patches that disable many common manual pinning implementations for you.
QUESTION
I'm new in Java and I don't know how can I send a terminal command by code. The device uses Android Nougat 7.1.2. What I need to do is send the following commands "su pm disable com.android.systemui" to the terminal after the user pressed a button. I need advice how to do that, I don't know if it's possible. Sorry for the dumb question.
Note: My original problem was to deactive permanently the nav bar and the notification bar in my system (I have root access) and this is the solution I have chosen.
