Deploying on other platforms as well

[tomy]

Hi all,

I used Qt Installer Framework (QIF) to make an installer for my app. It was very complex, and ...ed me until I reached the end point. :)

Anyway, it works well on Windows now.
I have heard this about Qt:

Code Less
Create More
Deploy Anywhere

It appears to be correct. But my question is should I return to those Docs once again to make my app work on Android?
Honestly I feared looking at Docs for that. (They are really complicated)
Does it take the same time to make it work on Adnroid as it took to make an installer using QIF?

Thanks.

@tomy In case of android, QtCreator itself can create an apk which can then be readily installed on android devices.

@tomy

it's not quite as easy as @p3c0 wrote it.

Beforehand you'll have to create your android -kit.
Install SDK,JDK and NDK and link them with QT, create an Manifest etc. It takes a moment to setup, but the docu will help you here

But
once you have succesfully build/compiled your project, qt automaticaly creates an apk for you, in the Release/Debug directory.
Which you only have to copy to your Android device/ Google-Playstore

[p3c0]

@J-Hilk Ofcourse. Everything needs some pre-requisites ;)
What I wanted to convey that you dont need extra installer framework for creating android apk's and that it can done from the QtCreator itself.

What both of you said was showing the process easy; it made me pleased. Thanks.

But I need a tut or an example to start and get the end. Honestly, I'm aware of none of the things you mentioned. (Just like QIF previously).

OK. how should I start? Is there any tut with a example except for Docs? I like anything around the world except for Docs.

Here you go:

[tomy]

Thanks p3c0,
Pardon me, but isn't there any other tut you are aware of rather than Docs?
My Qt Creator is 5.7 and not 5.8. Matters?

[p3c0]

@tomy Unfortunately no. But a quick google search throws some good results. You can try one of them. If you encounter any errors, feel free to ask here :)

[tomy]

Thanks. My Qt Creator is 5.7. Is it good or I need to install 5.8?

[p3c0]

@tomy Yes Qt version 5.7 will work. Installing newer versions are always better unless there are any regressions.

[J.Hilk]

@tomy
5.7 is fine,
But I personaly try to be always on the leatest release version. Usually lots of bug fixes and new features and very few incompatibilities.

@p3c0

Here you go:
http://doc.qt.io/qt-5/androidgs.html

Using this link I went for installing Android Studio 2.3.2. Then went to Download the NDK and Tools.
for that, first I created a new project (just by following the wizard) -> Tools > Android > SDK Manager > SDK Tools tab.
My page looks this way and there is no LLDB, CMake, and NDK, to check their boxes!

[p3c0]

@tomy You dont need to do anything in android studio.
After you install Qt, follow rest of the tutorial:
http://doc.qt.io/qt-5/androidgs.html#installing-qt-for-android

[jsulm]

@tomy In the bottom right corner there is a check button "Show Package Details", click on it...

[tomy]

@jsulm
I'd previously checked that box but there wasn't/isn't those items.

@p3c03):

@tomy You dont need to do anything in android studio.

Let's us clarify the items:

I'd previously installed Qt 5.7. OK?
Then I installed Android Studio.
Then I downloaded jdk-8u121-windows-x64-demos and downloaded and installed jdk-8u121-windows-x64.
Then I went for that link on this path.

One question: what files should be located for each "Browse" part of JDK Location, Android SDK Location and Android NDK Location there?

And as well as, when I want to download NDK by the download button there, it again directs me to the previous link I mentioned above.

[p3c0]

@tomy

what files should be located for each "Browse" part of JDK Location, Android SDK Location and Android NDK Location there?

the root folders which you get when you extract them

And as well as, when I want to download NDK by the download button there, it again directs me to the previous link I mentioned above.

Download this (if linux host):
https://dl.google.com/android/repository/android-ndk-r13b-linux-x86_64.zip

from here
https://developer.android.com/ndk/downloads/index.html

[tomy]

Thank you.
I did those and also download apache-ant-1.10.1-bin. Then set the folders as this. Please take a look at the warning message right on the bottom of Android SDK Location!

then I continued by Creating The Project:
In number 7 (Select kits), I should select a kit for my new project. When click on Manage to select the Android, it again shows the page with the warning message!

I tried well to select a folder as root but wasn't that successful!
Two questions:
1- How to solve this massage please?
2- Which kits should I select? Only Android, or I can select all kits?

Android studio is not the same thing as the SDK however I don't know where the SDK is located with the Android Studio installer. I usually get the command line tools from the bottom of the download page.

You mean I downloaded and installed Android Studio uselessly?

I usually get the command line tools from the bottom of the download page.

I think, anyway, we should have a SDK for put its path to the kit page, not?

[SGaist]

No, I just don't know where the SDK is located when you install Android Studio.

However, Android Studio itself is, indeed, not needed to build Qt applications.
