How to set up the FMOD audio library in Qt Creator for Android

I have created a few topics:

ANDROID_EXTRA_LIBS

I guess
if your app is built with Qt6, use QT_ANDROID_EXTRA_LIBS.
Use ANDROID_EXTRA_LIBS for Qt5

How do I view the contents of an APK file?

APK files are saved in a compressed .ZIP format and can be opened by any Zip decompression tool. Therefore, if you would like to explore the contents of an APK file, you can rename the file extension to ".zip" and open the file, or you can open the file directly through a Zip application's open dialog box.

Open or list your apk file to make sure these libs are added in.

Try the latest Qt6 if you prefer Qt6. Qt-6.2 is new in Qt 6.
I would prefer to use Qt5 for this. Especially your Android version is so old.

You can download it here: https://www.dropbox.com/scl/fi/m7hk76cia49451mhsoiny/android-build-with-fmod-for-forums.apk?rlkey=h2cnav1e6bl7s3ixidqi4nnsf&dl=1

Could you try to run it on your smartphone?

Sorry. I forgot to write what I use. I use: FMODE 2.02.16 API version, JDK 17, NDK 22, Qt 6.2.4, and Redmi 4x (Android 7)

Yes, libfmod.so is there. But How to make sure that the path is corrent?

[JoeCFD]

@8Observer8 they are all together. No path issue here.

[8Observer8]

@JoeCFD please, try to run it

I mean, maybe Qt try to find it on the wrong path that I wrote in pro-file. I found somewhere that the folder must be named jniLibs:

contains(ANDROID_TARGET_ARCH, armeabi-v7a)
{
    ANDROID_EXTRA_LIBS += $$PWD/jniLibs/armeabi-v7a/libfmod.so
}

[8Observer8]

I tried to use lib instead of jniLibs but the result is the same.

contains(ANDROID_TARGET_ARCH, armeabi-v7a)
{
    ANDROID_EXTRA_LIBS += $$PWD/lib/armeabi-v7a/libfmod.so
}

@8Observer8 Very few people have phones with Android 7.

I think the smaller the version, the more you can capture the audience. Let's say if you build for Android 4, then the application will run on Android 4, 5, 6, 7, 8, 9, 10, 11 and so on. But if you build on the latest version of Android, then the audience will be very small.

[JoeCFD]

@8Observer8 then you need to add the support up to Android 13. Did you do it? Or you simply made Android 7 support?

my app supports Android 11, 12 and 13.

[8Observer8]

@JoeCFD said in How to set up the FMOD audio library in Qt Creator for Android:

my app supports Android 11, 12 and 13.

I think Android is backward compatible. That is, if I created applications with the selected Android 4, this means that the application will work not only on Android 4, but also on Android 5, 12 and 13.

[JoeCFD]

@8Observer8 I guess not. I built my app for Android 11 and 12 at first. And it did not work on Android 13. I had to add 13 support in the build.

[8Observer8]

@JoeCFD I need to check it out. Later, I'm going to create a blank window for Qt for Android 7 and run it on Android 12. I can't believe the blank window won't work.

[8Observer8]

@JoeCFD My only guess is that an app built for Android 11 doesn't work on Android 13 because it uses APIs that were removed in Android 13, but unless you're using backwards compatibility hacks, then early apps should work on more number of new devices. But this is only my assumption, which I myself have to verify by experience.

[8Observer8]

I currently have an Android 13 smartphone. I tried to run my music application using OpenAL. It works on smartphones with Android 13 and 7. This is very good, because I thought that I would have to make a separate build in the APK for each version of the smartphone, starting from Android 7 to13.

[JoeCFD]

@8Observer8 What I did is to add all SDKs of Android 11, 12 and 13 to the project, but I made only one build . My app works fine in 11, 12 and 13.

Last time you wrote that if the application is built for Android 7 and Android 12 SDK, then it will not work on Android 13. Interestingly, I was unable to remove the Android 12 SDK from Qt Creator. Qt Creator says that Android 12 SDK is required:

I don't have the Android 13 SDK installed, but my app works fine on Android 13 and Android 7:

[8Observer8]

My APK file that I asked to try running on Android 13 two weeks ago turned out to work on Android 7 and Android 13. I compiled OpenAL to work with audio for Android 10 (When building OpenAL, I used Android API 29, which is compatible with Android 10). The compiled library works on Android 7 and Android 13. I tested it on real devices. I have the Android 7 and Android 12 SDKs installed in Qt Creator in the SDK manager. Tried to run on Android 7 and Android: OpenAL, Box2D, Bullet Physics and OpenGL ES 2.0. That's all you need to develop 2D and 3D games. Now I'm not interested in wasting time on FMOD.
