Android app doesn't run

[JoeCFD]

@mzimmers the SDKs from Android SDK Manager are not in your kit yet. Click SDK Manager button to add them.

[mzimmers]

@JoeCFD it doesn't work - there's nothing in the package window to add when I've selected JDK 11.

[ekkescorner]

@mzimmers I'm using JDK 17 for Qt 5.15.15 and 6.6

[JoeCFD]

@mzimmers I am running Qt 6.6.1 on Linux with qtcreator 11.0.3 and do not have any issue with the settings.

SDK path is not writable?

[mzimmers]

@JoeCFD I'm running on Windows 11. According to the properties of my Sdk folder, it was partially read-only, but I changed that, and it didn't help.

When I try to run the SCK manager, I get this error:

[JoeCFD]

@mzimmers

The error message indicates that you are trying to run a Java class file compiled with a higher version of the Java compiler than the version of the Java Runtime Environment (JRE) you have installed.

In this case:

Class file version 61.0 corresponds to Java 17.
Class file version 55.0 corresponds to Java 11.

==============================================================
Your installation is messed up.

@JoeCFD said in Android app doesn't run:

Your installation is messed up.

Well, that's an understatement. From a terminal, I get this:

C:\Users\michael.zimmers>java -version
openjdk version "21.0.1" 2023-10-17 LTS
OpenJDK Runtime Environment Temurin-21.0.1+12 (build 21.0.1+12-LTS)
OpenJDK 64-Bit Server VM Temurin-21.0.1+12 (build 21.0.1+12-LTS, mixed mode, sharing)

Is this not the same JRE instance that Creator is trying to use?

[JoeCFD]

@mzimmers It is likely some java classes in Android/Sdk were built in Java 17 at the beginning. They were not rebuilt when you switched to Java 11.

Wait: you have JDK 21?

[mzimmers]

@JoeCFD said in Android app doesn't run:

Wait: you have JDK 21?

I have JDK 11, 17 and 21. I just don't know which one to use in my JDK/SDK/NDK/tools/JRE cocktail.

[JoeCFD]

@mzimmers I guess you can not have all of them. Remove 17 and 21 and SDK. Reinstall SDK if you use Java 11 which is recommended by Android for Andorid 13.

@ekkescorner wrote he is ok with 17. I have not tried it. You can try it out as well.

[mzimmers]

@JoeCFD but according to JKSH's post this is going to create a mismatch.

[JoeCFD]

@mzimmers I do not know the mismatch issue. I have only Open Java 11 in my Linux computer.

[mzimmers]

An update: I was able to install my application from the command line (using adb.exe). So, there's nothing wrong with my .apk file; it appears the problem is in Creator 12.0.1 (or the way I'm using it).

[ekkescorner]

@mzimmers perhaps you run into this: https://forum.qt.io/post/785169

[ekkescorner]

@mzimmers you can try a QtCreator 12.0.2 snapshot: https://download.qt.io/snapshots/qtcreator/12.0/12.0.2/28/
let us know if this works better

[Kim Nancy]

The error suggests an issue with the AndroidManifest.xml activity class. Verify correct package and activity names, check for recent changes, and ensure accuracy in your project's configuration.

This definitely helps. Combined with regenerating the android files, and deleting the build directory, I'm past that error. (I'm onto another error, but I think this is my doing. I'm posting the relevant output here.)

I think this has to do with a recent restructuring of my project files and folders.

So:

• delete the build directory
• clear your Qt Creator cache
• use Creator to generate but NOT modify AndroidManifest.xml

appears to be a successful procedure, if my above assumption about my project restructuring is true. I'll do some more experimentation and report back.

Oh, I tried 12.0.2...no improvement. Thanks for the link, though.

@mzimmers said in Android app doesn't run:

use Creator to generate but NOT modify AndroidManifest.xml

if you mean by 'generate' to create templates then you must do your customization in AndrouidManifest: change application name, activity name and other properties of AndroidManifest. depends from your use-case

@mzimmers said in Android app doesn't run:

this lib is needed in your app. Add it to your build script.

@mzimmers take a look at https://github.com/KDAB/android_openssl to get openssl
