Qt error when attempting to compile android APK

Lordful

Hello,

I'm trying to compile a simple project (Hello World) for run it on a smartphone on Android. But I can't reach that goal because there is a mistake inside the SDK and I can't solve this. I search on the internet if people has had this issue, they will but few months ago.

CF : https://forum.qt.io/topic/55326/solved-qt-throwing-error-when-attempting-to-compile-android-apk/2

The configuration of Qt Creator seems to be good, I add path for JDK, SDK, NDK and Ant but anyway, I can't compile ..

That's the error, which aren't very helpful :

Thanks a lot !

Hi,

I don't have a direct answer for that, but as an alternative you could use gradle. There's a checkbox for that in the Android Settings from Qt Creator. Note that you will have to do a clean build once checked.

Hope it helps

Hi,

I try to do that but I have this error :

* What went wrong:
Execution failed for task ':compileDebugAidl'.
> com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command '/Users/me/Documents/Android/sdk/build-tools/23.0.2/aidl'' finished with non-zero exit value 139

Do you have any idea of solutions ?

SGaist

Did you do a full rebuild of your project ? i.e. nuke the shadow build before compiling.

Lordful

Yes of course, to be sure, I deleted the whole folder which came after building.

But the error is the same as the error with ant, it's always about aidl inside of sdk/tools/ant/build.xml.

Pablo J. Rogina

@Lordful have you taken a look at this post? It looks similar to your issue and there are some suggestions, mostly related to Ant.

Lordful

@Pablo-J.-Rogina Hum yeah, I read that but it's an old topic, maybe it's because API 23 has problems ?

EDIT : I tried to build with API-10 and API-18 but there is this error, again and again :

[mergemanifest] Manifest merger disabled. Using project manifest only.
     [echo] Handling aidl files...
     [aidl] Found 2 AIDL files.
     [aidl] Compiling 2 AIDL files.

@Lordful mmm it looks definitely connected to Ant... Could you please describe your environment (OS, tools version, installation paths)?

Also, have you taken a look at build.xml:664, the line with the error?

In addition, this bug report may be applicable to you

Lordful

@Pablo-J.-Rogina Here is the informations :

OS : OS X 10.7.5
JDK : 1.8.0_73
path : /Library/Java/JavaVirtualMachines/jdk1.8.0_73.jdk/Contents/Home

SDK : 24.4.1 - Latest on official website
path : /Users/me/Documents/Android/sdk

NDK : r11b-darwin-x86_64 - Latest on official website
path : /Users/me/Documents/Android/ndk

Ant : 1.9.6
path : /usr/local/Cellar/ant/1.9.6/bin/ant

EDIT : Build Tools: 23.0.2

Available version of Android : API 18, 10.

Here is the error on line of build.xml :

<aidl executable="${aidl}"
                    framework="${project.target.framework.aidl}"
                    libraryBinAidlFolderPathRefid="project.library.bin.aidl.folder.path"
                    genFolder="${gen.absolute.dir}"
                    aidlOutFolder="${out.aidl.absolute.dir}">
                <source path="${source.absolute.dir}"/>
</aidl>

I test each value of this and there are all good, except project.library.bin... which isn't a value.

Solved by using an other sdk build-tools, I installed sdk build-tools 19.1 and I can build now.

Next step : Launch emulator and my application on this old mac with 2 GB ram, actually, 1.80GB are used. It will be funny :D

Pablo J. Rogina

Glad you solved it, please don't forget to change the post status accordingly. On the emulator side... be patient!

Lordful

@Pablo-J.-Rogina As I said ... it was to simple to be true :D

First, I can't launch an emulator, I guess that It's because I don't have a lot of RAM.

Second, I tried to use a smartphone ... one more time, Android have a problem because Qt can't find my device even after installing a specific driver.

I found a solution, it's to add manually the smartphone to adb and then, kill-server and restart the adb server. That's where is the problem because I can't do anything with adb without receive :

Illegal Instruction : 4

So, I change the version of plateform-tools but this time, the problem is still present ...

I didn't like Android and I'm still not starting to like it right now ... :D

SOLUTION : Download an older platform-tools and replace the folder by the download folder.
