Hello Guys,

So via online installer I installed Qt 6.6 with all android,
configured android:

but upon build I have this error:

FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':checkReleaseAarMetadata'.
> A failure occurred while executing com.android.build.gradle.internal.tasks.CheckAarMetadataWorkAction
   > 2 issues were found when checking AAR metadata:
       1.  Dependency 'androidx.core:core:1.10.1' requires libraries and applications that
           depend on it to compile against version 33 or later of the
           Android APIs.

           Recommended action: Update this project to use a newer compileSdkVersion
           of at least 33, for example 33.
           Note that updating a library or application's compileSdkVersion (which
           allows newer APIs to be used) can be done separately from updating
           targetSdkVersion (which opts the app in to new runtime behavior) and
           minSdkVersion (which determines which devices the app can be installed

Deprecated Gradle features were used in this build, making it incompatible with Gradle 9.0.
You can use '--warning-mode all' to show the individual deprecation warnings and determine if they come from your own scripts or plugins.
For more on this, please refer to https://docs.gradle.org/8.3/userguide/command_line_interface.html#sec:command_line_warnings in the Gradle documentation.

I have installed SDK and Image for v34:

and i wonder how come it says:

: is currently compiled against android-31.

I cant even set the min and target SDK platform:

I have basically followed the video guide: https://doc.qt.io/qt-6/android-getting-started.html
so what do I do wrong?

JDK 17 or 11 did not help,
however what i did is changed version of androidx.core:core in projectfolder/android/build.gradle on line 21:

from:

implementation 'androidx.core:core:1.10.1'
implementation 'androidx.core:core:1.8.0'

thos i didnt try any versions in between like 1.9.0, i tried directly 1.8.0 which worked...

hope this help someone as Qt 6.6 for me does not like to use API 33

then I just have a huge list of errors on build:

33 actionable tasks: 33 executed

and installing newest NDK does not help in any way

@JoeCFD yea but i still dont know what to do :( i reported a bug as I think its not correct that fresh qt 6.6.0 asks me for v31:
instead of v33 which is not compatible with JDK or NDK or Graddle which QT is trying to use

@shokarta First, your JDK version 21 may not work(not sure). Even for the latest Android 14, Java 17 is needed. But you have 21. My target Android versions are 12/13. Therefore, I use Java 11.

Android 	Java 	API and language features supported
14 (API 34) 	17 	Core libraries
13 (API 33) 	11 	Core libraries
12 (API 32) 	11 	Java API
11 and lower 		Android versions

Better to check the versions of all the packages you use are compatible.

JDK 17 or 11 did not help,
however what i did is changed version of androidx.core:core in projectfolder/android/build.gradle on line 21:

from:

implementation 'androidx.core:core:1.10.1'
implementation 'androidx.core:core:1.8.0'

thos i didnt try any versions in between like 1.9.0, i tried directly 1.8.0 which worked...

hope this help someone as Qt 6.6 for me does not like to use API 33

little update...
above solution works only with JDK 17... but also removing the line completly works with JDK 17... however if i update back to 21 (like the QT installation video from the link above) then nothing works whatsoever...
i guess only updating API to 33 would work, which from the issue explanation my Qt 6.6 does not like.

The following worked for me-

  • Install Android Build Platform SDK - android-34 from SDK manager.
  • Install Android Build tools version - 34.0.0 rc3 from SDK manager.
  • Install OpenJDK 17 (and not higher versions - they are not compatible)
  • Restart Qt Creator.
  • Set JDK path.
  • Set Android Build tools version as 34.0.0 under Projects>Build (Under your Android Qt 6.x.x Clang etc,)>Current Configuration>Build Steps>Build Android APK>Application> ...
  • Set Android Build Platform SDK as android-34 under Projects>Build (Under your Android Qt 6.x.x Clang etc,)>Current Configuration>Build Steps>Build Android APK>Application> ...
  • Clean, Rebuild
  • I just want to make it clear for new readers : with current (Qt 6.6, QtCreator 12.0.2) version, you have to do both :

  • use JDK 17 not 21
  • modify your projectfolder/android/build.gradle as stated :
  • implementation 'androidx.core:core:1.8.0'
    

    instead of

    implementation 'androidx.core:core:1.10.1'
    

    Not doing any of these lead to errors in my case.
    The error when using Jdk 21 contains :

    javac\debug\classes\org\qtproject\qt\android\bindings\QtLoader$2.class: D8: java.lang.NullPointerException
    			

    @Samuel-Adesola said in Online installed Android Qt 6.6 but build requires newer version?:

    I had the same issue, I am currently on Qt 6.5.3, I just replace the JDK 21 with JDK 17 and it worked

    This solved the same issue I had on Qt 6.6.2.

    @simranjeetsingh
    Hii!!
    I I'm having trouble building my Android app with QT 6.6.1. Despite installing JDK 11 and configuring Android 13 (API 33), I keep getting an error stating that a drawable/icon is not found, even though I've added it to my build directory. Additionally, I'm getting warnings about deprecated Gradle features, making the build incompatible with Gradle 9.0.

    Could You please help me troubleshoot this issue? I've attached a screenshot for reference.
