Android: Qt 5.5 Compile time Error

vahidnateghi

I've had some experience with Qt but none with android in Qt, I've downloaded:

Qt5.5-Android 

Jdk-1.8

NDK-r14

ant-1.10

SDK r26

and I've given the appropriate addresses to the sections in Tools->Options->Android

However, When I create a brand new project, connect my phone (Samsung Galaxy Note 5, with USB Debugging ON) and select armeabi-v7a(GCC 4.9, Qt 5.5.0), I get the following errors in compile time:

19:09:46: Running steps for project TestAndroid1...

I've been stuck in this for a couple of days now and I appreciate any suggestions, Thank you in advance.

@vahidnateghi At which step does this happen (you should post the whole command line causing this error)? Is it during deployment to the device/emulator?

vahidnateghi

@jsulm Thank you for the reply. Right now I'm at work, I'll post the whole compile output as soon as I get home in a few hours.
I'm not sure but I think it is during the deployment operation.

vahidnateghi

@jsulm Ok, So I've just updated the Question, thanks again.

vahidnateghi

any one? :(

jsulm

@vahidnateghi Can you try with a more recent Qt version? And did you try to deploy to the emulator?

vahidnateghi

Thank you @jsulm but I actually solved the problem! The problem was my SDK version! apparently after SDK r25.2.5 ant is not supported by the SDK anymore!!! So I used an older version of SDK and SOLVED!
See My StackOverFlow Question
Also See This.
Also See This for adding ant to newer versions of SDK (Haven't tried this myself yet!).

@vahidnateghi You could just use Gradle which is the standard and supported by QtCreator (you just need to tell QtCreator to use Gradle).

vahidnateghi

@jsulm hmm yes I'll try Gradle as well, thank you!
