    Hi everyone,
    I'm currently working on an mobile app for android.
    I did all the setup, as described (installed jdk and ndk / android sdk).
    Qt Creator recognizes my mobile correctly, when its connected to the development pc.
    When I wanted to deploy the app in my mobile (running android 4.4.2), the process threw up several errors,
    all of them related to java.

    "java.lang.NoClassDefFoundError: Could not initialize class org.codehaus.groovy.vmplugin.v7.Java7
    at org.codehaus.groovy.vmplugin.VMPluginFactory.<clinit>(VMPluginFactory.java:43)...".

    Followed by more than 100 lines of errors "at...".
    By the way, openSSL is not set up (it was marked as optional).

    Hope there is someone to help me, thanks

    @Phips04 said in Develop for android java issues:

    I didn't remember that version 8 is the recommended one, installed 15.

    Yes, it is no clearly defined ==> https://doc.qt.io/qt-5/android-building.html.
    JDK 8, still recommended for best compatibility, but starting with Qt 5.15 JDK 11 could be used.

    Side note: if you search on internet java.lang.NoClassDefFoundError: Could not initialize class org.codehaus.groovy.vmplugin.v7.Java7, all matches you will found will clearly detail the issue. The gradle version is not compatible with the selected JDK.
    For Qt 5.15, the used gradle version is 5.6.4 (just check in <QT_DIR>/5.15.0/android/src/3rdparty/gradle/gradle/wrapper/gradle-wrapper.properties)

    running android 4.4.2

    Android 4.4.2?! Do you really have to use such an old version?
    What Qt version do you use?
    To build for Android 4.4 you need Qt 5.12 or older.
    See https://doc.qt.io/archives/qt-5.13/android.html and https://doc.qt.io/qt-5.12/android.html

    I think your Android version is too old, according to Qt wiki, Android API level 18 (Android 4.3) is required and API 21 (Android 5.0) is recommended.

    My mobile is a samsung galaxy S3 Neo running android 4.4.2, and I'm using QT 5.15.1.
    However it told me, that the build process failed because of java. I just copied the details:

    I'm not sure, but maybe its not android itself being responsible for the problems.

    @Phips04 It does not matter at all what device you attach to your PC,

    what does matter is what minimal android version you set inside your manifest. Did you change it there ?

    No, the Android manifest ==> AndroidManifest.xml
    Double click on it in QtCreator to start the editor:

    This is how it actually looks like, the option to set the sdk is disabled.
    I made sure, that the sdk's I want to use are installed. (Sry I'm new to qt)

    @Phips04 Did you check QtCreator Android configuration?

    In Tools/Option/Devices, select tab "Android":

    Java and android settings are ok, in the android settings there is no "ndk-bundle". But the second entry exists, as I mentioned OpenSSL is not set

    This is your problem, ndk-bundle is mandatory for Qt!

    Extract from the Qt documentation:
    Use the sdkmanager command line tool to update the packages list and then install the essential packages:

    cd <ANDROID_SDK_ROOT>/tools/bin/
./sdkmanager --update
./sdkmanager --install "platform-tools" "platforms;android-29" "build-tools;29.0.2" "ndk-bundle"

    @Phips04 This seems to be a well know issue with Android:

    • https://stackoverflow.com/questions/60730615/sdkmanager-warning-could-not-create-setting-java-lang-illegalargumentexcepti
    • https://medium.com/@s89707192/if-you-have-the-issue-652c7c1ad5d0

    You can try:

    cd <ANDROID_SDK_ROOT>\tools\bin\
sdkmanager --sdk_root="<ANDROID_SDK_ROOT>" --update
sdkmanager --sdk_root="<ANDROID_SDK_ROOT>" --install "platform-tools" "platforms;android-29" "build-tools;29.0.2" "ndk-bundle"

    @Phips04 do it by hand than, open the android manifest.xml in a text editor
    and change the version there

    The .xml can be evaluated and I set the entries. Min sdk is 21 (android 5) and target is 27 (android 8.1). The error still is the same

    What do you mean with "you can't"? Is the dropdown combobox grayed out or is the list empty?
    Do you have restart Qt Creator after updating SDK root?
