I'm trying to setup Android Studio + LiquidFun. I follow a lot of tutorials like these:
http://www.shaneenishry.com/blog/2014/08/17/ndk-with-android-studio/
http://tools.android.com/tech-docs/android-ndk-preview
But either isn't comprehensive or isn't work. I tried all, copy directly the files (C++) to my project, tried to import using NDK, tried to fix NDK with gradle, etc. But nothing works. I appreciate it too much if anyone could help me to solve my problem or to install Liquidfun properly.
Thanks.
Did you try following the instructions from here:
https://google.github.io/liquidfun/Building/html/md__building_android.html
They seem clear enough. You need the NDK on your PATH for ndk-build to actually do anything.
If you are going to use Java, you may want to try JLiquidFun, a derivative of LiquidFun with enriched Java bindings and pre-compiled native libraries.
try this instead
build .so, copy to AndroidStudio Project's lib dir
last year,i was compiled successfully, use Old version NDK and Android SDK.（This is very painful）
i think need It needs to be adapted to the new Android SDK
In particular, build statements in.mk files or.py files ，
Because you're using the old version of the command line command

I have created a Non-Qt C++ (CMake) project using Qt, and I am able to build it using MinGW, MSVC compiler.
So in short, when I am opening my test project I can select the generators under Run CMake Window. I have issue with other platforms.
When I am trying to Add a kit for Android, there are no generators available in the list. I tried the same thing on Macbook, there also the same problem.
I need help on this issue, I couldn't get the proper steps to build the CMake based project for Android/iOS using QtCreator.
P.S. Installed CMake version is 3.2.1 and Qt Version is 5.5, I have installed Android SDK, NDK , and and Java
I would love to tell you "just check this box in the options dialog and it will work", but, unfortunately, there is no generator that you can use to build an Android/iOS project from a CMakeLists.txt file.
I found alternatives, in all cases, I don't think your have a chance to port a whole huge CMake-based project that used to work on Windows (with lots of libraries and 3rd party libraries) work on Android in less than a few days of work....;-)
Personnaly, I wrote a small CMake function generating the .pro file manually from my CMake scripts. It started small but is now huge and it's difficult to share it with you. But, basically, I started from this post on a Qt forum. It creates a simple .pro file that does not work that bad and then you can extend it for your own needs. I like this solution because I have full control on generated .pro file (mine can now build on PC, Android and iOS...but I had a hard time to have this fully work).
Apparently, there's also a way to add a Qt-android CMake support using this open source stuff: https://github.com/LaurentGomila/qt-android-cmake. But I never tried it. You may want to have a look to it. If it works, it may be more convenient that writting your own script generating .pro files. Apparently, it builds an Android apk using androidqtdeploy but without using QtCreator. There's also an iOS support.
Finally, the best may be to have CMake propose a QtCreator "generator" (it would generate .pro files, like CMake generates sln/vcproj files when using Visual Studio generator or makefiles for g++ generator....), but there is no such generator supported. I reported this to CMake team some time ago hoping they could fix that. I understood that there was and would be no plan to do that because CMake targets only "compilers" as "generators" and "QtCreator" is not really a "compiler", it's a "IDE" using external "compilers" to build (MinGW, MSVC, CLang, Android's NDK g++...). It's a shame because CMake known all your project information and could easily generate a .pro file....so, as, CMake is opensource, one may extend CMake with a custom QtCreator file generator...and share it with the whole world,it would be wonderful!
Hope this will help you!
I am trying to get the OpenCV library working with android. I imported this library project into eclipse and made a new android project (the one I will develop) and just. I set the build path to include the OpenCV project in eclipse. However, when I run my new project, it says
[2014-10-13 19:41:57 - OpenCV Library - 2.4.10] Could not find OpenCV Library - 2.4.10.apk!
From what I understand, my new project should automatically pull in the library project and install it. I am wondering if I am missing any steps (because it doesn't seem to be pulling in the project)? Does it have to be the same target sdk? I am quite sure I followed all of the OpenCV installation guide and have no compile errors in the projects. Also if I load up the sample projects by directly installing the apks they seem to work fine. I even tried it with the OpenCV Manager app already installed but that didn't work either. Thanks for any help.
Just add the OpenCV library project as shown below, the problem will go.
Project -> Properties -> Android
and press OK.
You should check "Library" build option in Eclipse for OpenCV android project.(Not your project)
Clean your OpenCV library,build it again and check in OpenCv library->bin->opencv library -X.X.XX.jar if there is a file (X==> VERSION)(see picture).See this for .jar file. If this file does not exist then your library is not generated then check the video it might help This should help if your library is not built.
My personal experience:I wasn't able to generate the jar file for some reasons using OpenCv2.4.10 .If the same happens to you consider using OPENCVTEGRA library it works at least for me.
Answering 1st time. Hope this helps
I am new in android. I see a lot of android libraries out there like github.com but when I download them none of them are a *.jar file like this one:
NumberProgressBar
It seems that all these libraries are for android studio NOT eclipse (Am I correct? This is important).
My question is: How do I use these libraries in eclipse?
I tried to import the downloaded library as an android project and then mark it as "is library" and then add to my project, but that did not work.
That library is designed to be built with Gradle for Android (with or without Android Studio), producing an AAR.
Eclipse does not have native AAR support. I have published a recipe and a Ruby script to convert an AAR into a library project that Eclipse can use, though I have not tested it much.
Or, you can download the source code and attempt to reorganize it into an Eclipse-style library project.
I just downloaded it and add it as library project and everything looks fine. How do you do it, it's extremely simple. Let us know in which step you have a problem so we can figure out what is wrong.
You have to build the library first.
For your example, read the Readme file, section 'Build'.
A project that I am trying to build has one of these, and I want to know exactly which tools are needed to build the project. I see some reference to NDK when I search but is that the only tool? It appears that this file is making a jar file, I see no reference to native code ( c++ )
The Android.mk files in the SDK samples are required to properly include the samples in the SDK build (if you are actually venturing into that territory). These have no bearing on what you are doing when you use the sample. To the OP, I'm not sure if you are using a sample project, but if you are, you can ignore this file.
the best answer to your question is reading this article:
Android.mk file syntax specification
https://android.googlesource.com/platform/ndk/+/4e159d95ebf23b5f72bb707b0cb1518ef96b3d03/docs/ANDROID-MK.TXT
after reading it you can figure out the idea behind the android.mk file.
cheers
I've seen some of the Android sample code come with an Android.mk file for no apparent reason -- maybe this gets auto-generated upon project creation if you happen to have the NDK installed or something. Android.mk does seem to be an NDK-specific thing.
So if there's really no native code involved, then if you're looking to build from the command line, make sure you have the JDK, Ant, and Android SDK installed.
Then take a look at
http://developer.android.com/guide/developing/projects/projects-cmdline.html#UpdatingAProject
After you run the "android update project ..." step, you should hopefully be able to do an "ant debug" to build the application.
I've been doing all my builds using ant on the command line (Ubuntu 10.04). I loaded up the 2.3 SDK and made the necessary path changed (platform-tools). Now my builds don't include the jars in my libs directory. Any thoughts on what I need to change?
The Ant build system now requires Ant 1.8+
Unfortunately it "works" (broken) with 1.7 because we rely on a new behavior in 1.8, not a new task or attribute that would break 1.7
i'm not familiar with the ant builde for android as i'm usig eclipse(why shouldn't ou ? it generates build.xml autotmatically).
In any case whe you say platform tools you mean $ANDROID_HOME/platforms/android-9 ?
Are you sure it's needed for ant ? i know the ant build file itself is pretty empty and most of the work is done in their java .sh files so it's ard to tell what they are missing, cold it be you found a bug in their new SDK ?
I've got other more serious problems with SDK2.3 (the AVDs are bust). I'd set up Ant builds OK to work on 2.2 and was looking to see if an Ant build would run. My custom build.xml overrode quite a bit of the stuff in ant_rules_r3.xml but still used some of it. I noticed that this has now been removed and replaced with main_rules.xml, which is a bit different. 'project.libraries' replaces 'android.libraries' for one thing. It's probably worth you looking at the differences if your build.xml was based on ant_rules_3.
I'm not going to look at it myself until my main problem is fixed.
