Qt 5.1.1 Android
-
Hello everybody and thanks for your help that i have already asked you several times. I think this question concerns many who are working with Qt. I have a software which has been built for windows and linux and is working fine. Is it possible to compile this application for android like i have compiled it for linux and work fine? What changes have to be done to run a windows/linux for an application to run in android ?
Thanks! -
There isn't much that needs to be done at all if you are using Qt Creator. You basically have to download the android build of the libraries, android sdk, android ndk, and apache ant.
-
what packages of qt do i need ? The software has been developed only in Qt
-
"The ones labeled android":http://qt-project.org/downloads
-
yes i have downloaded this package. Did you tried to compile a ready made application which was built in windows to android ?
-
Also, once you have downloaded and installed the android sdk, you have to run the sdk package manager and install an actual sdk version.
-
Yes. I have used Qt 5.1.1 to target windows, linux, osx, ios, and android.

Here are some links to help you setup creator

Hello all. As i have told you yesterday today i compiled my software for android. the whole toolchain was built like in this video :
http://www.youtube.com/watch?v=_nkhlhBwkjk
The build has been done but when i am trying to deploy i get this message
error: Cannot find ELF information.Anyone help?

I forget what that means, but here are a few things to check. Have you setup your device properly? Do you have a simulator working? The android sdk has a command called adb. It stands for android debug bridge. Run the following command, adb devices and make sure it shows that you have a connected device. If you are using a simulator, you have to make sure the setting in the simulator, Use host GPU is enabled.

i use android sdk as emulator. i don't use real android phone. android sdk isn't enough ? as you can see in the video only android sdk is used.
-
can anyone help ? i am looking for that 2 days.!

I had such "Cannot find ELF information" error too. Looks like it appears after project structure changes and when your android folder contains lots of outdated files.
I've just removed an android install folder (INSTALL_ROOT="/home/user/project/android" install) where the projects put all the data. And run deploy again.
I hope it will help.
-
Android folder could be found at "Projects" - >"Run" - >"Copy application data". Just press "Details" and you can change it in "Make arguments".
-
Sorry i did not saw your answer.. can you explain again in more detail how to solve this ?
-
I'm not sure that it is exactly your problem, but I had the "Cannot find ELF information" error. It appeared after my changes in the project (.pro) file. I found that the problem was connected with outdated files in the "android" output folder.
By default it is located near the *.pro file, and it named "android". But also it could be moved to another directory in settings (look “Projects” – >“Run” – >“Copy application data”).
If you remove this folder, Qt Creator will create a new one, which will be correct for the current project.
By the way it's possible just to remove "bin" inside "android" I think that its stuff can cause the error. -
ok.. i will test it and answer, but i think that is not the problem..
-
I have tested that and get the message "Unable to start 'org.qtproject.example.Name". Any ideas ?
-
Check if you really have Qt Application in your project with name "Name".
