androiddeployqt release issues

[Marc_Van_Daele]

I'm using Qt 5.12.4 and when running the following command

<...>/androiddeployqt --input <...>/build-MyApp-Android_for_armeabi_v7a_Clang_Qt_5_12_4_for_Android_ARMv7-Release/android-libMyApp.so-deployment-settings.json --output <...>/android-build --android-platform android-28 --jdk /usr/lib/jvm/java-8-openjdk-amd64 --gradle

I notice two strange things

1. when running from QtCreator as part of a normal build (after selecting a release build in the bottom left), I see the following steps

:preBuild UP-TO-DATE
:preDebugBuild UP-TO-DATE
:checkDebugManifest
...

So it still seems to select debug versions of these tasks.
Any idea why? This also happen with a simple empty application

2. when running from the command line, I see

:preBuild UP-TO-DATE
:preReleaseBuild UP-TO-DATE
:checkReleaseManifest

but I also run into the following error

[Fatal Error] :3:214: The value of attribute "name" associated with an element type "item" must not contain the '<' character.
Could not read <...>/Qt/Android/android-sdk/platform-tools/api/annotations.zip
java.io.IOException: Could not parse XML from android/accounts/annotations.xml

Is this harmful? How can I avoid this?

Thanks in advance,

Marc

Fatal errors typically are harmful... Quite often build problems are due to the NDK version. 19c is the one to use.

I checked and I'm already using NDK-19c.

I did find out one more thing: the problem only occurs when signing the apk. This explains why it didn't happen from within QtCreator initially (where I didn't sign) and that it did happen from the command line.

The problematic file here is part of the sdk platform-tools/api/annotations.zip and this zip file seems to contain an invalid XML android/accounts/annotations.xml.

Apparently, this is an issue in the Google build tools: https://issuetracker.google.com/issues/116182838

Going back to platform-tools 28.0.0 fixed it for me.
I've closed this topic for now.
