Deploying to Android from QtCreator under mac osx

boggins

@SGaist Yes, tried gradle as well :)

SGaist

What version of the Android SDK and NDK are you using ?

boggins

I am using r10e of the NDK, and 24.3.3 of the SDK. I just downloaded them last week, I believe they are the latest versions available.

SGaist

Maybe a silly question but, do you have java installed properly ?

boggins

@SGaist Well it depends what you mean by properly ;)

In QtCreator I am referencing Java here:
/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home

(in Preferences->Android)

SGaist

That looks good…

Did you set the API level of your application to the same or a lower version corresponding to your device ?

boggins

@SGaist Yes I believe so. I've installed API 19 from the SDK manager, and I'm referring to API 19 under Projects->BuildAndroidAPK.

My device runs Android 4.4.4, which according to this:
https://en.wikipedia.org/wiki/Android_version_history
uses API 19.

I've also just installed the latest and greatest Java JDK just incase anything was wrong there - 1.8.0_51 - and I've updated the path in the preferences accordingly. (The path by the way is a little different from that required for 1.6 - it's now in /Library/Java.... whereas before it was /System/Library/Java...)

But I wonder is the problem more the detection of the android device - the fact that it's always showing a green dot (even when my tablet is not connected) is strange. And under Preferences->Devices it tells me that the android device is "ready to use" even if there's no device there.

The problem is less pressing for me now as I'm back home and have access to my linux system, but it would still be nice to know what's going wrong on mac osx.

SGaist

What do you get if you call adb devices -l ?

This is a demo video for deploying each different platform.

Check what the different with your operate.
And don't forget to rebuild your project.

Maybe you can connect with your android.
Just try it.

Sorry for the delay in replying to your suggestions. I am travelling again in the holiday season, and so I'm again trying to use my macbook to develop Android apps.

When I run ./adb devices -l, I see the device(s) OK - for example with my Nexus 7 tablet I see:

List of devices attached 
<some sort of device id>       device usb:24100000 product:nakasi model:Nexus_7 device:grouper

Similarly if I have an emulator running, I see the emulator listed.

Regarding the video, thanks, but I don't see anything that I'm doing differently, except of course that I have more recent versions of Qt, Android SDK, android NDK, java etc than in the video. Interestingly in the video, you can see the author also sees "unable to start <appname> " (as I do) in the application output window, but the app starts for him.

A recent query here by a user targetting iOS had issues deploying apps with QtCreator 3.5 which were resolved by using QtCreator 3.6 - I have just updated to 3.6 but I experience the same problems as before.

Thanks for any suggestions.
