@Malachi I think you are absolutely right!

Are you using Qt build for android? It is normally under android_* dir and is different from normal build.

@Gianluca-Bernardi I have default as well. Not sure how you got full before. Good to know you solved the issue.

This is your job to handle it. If permission is not granted, you stop your app or pop up a dialog to tell the user that the app can not continue.

@ekkescorner This issue will be fixed in next release.
Qt support said that overwriting Qt 5.15.11 androiddeployqt files with Qt 5.15.10 ones will fix this issue.
I don't like mixing versions, so I'm waiting next release while using Qt 5.15.10 which is good enough for my development.

Use QStandardPaths::writeableLocation to find the proper location. Use QDir and QFile to finish the save.

A complete compilation has already been performed several times.

I can not include a new class in the project.. or even a blank file that this error occurs.

Will the SDK, NDK and JDK settings be correct?

@Kim-Nancy said in Problem compiling for Android from Windows:

Seek assistance on Qt community forums for further support.

Ha, that's literally where we are.

In any case, this solved it for me: https://stackoverflow.com/a/68394638/8548472.

quite hard to help without any information..

I think it depends on Android OS version. For the latest version(s), I suspect @J-Hilk is 100% correct.

Would the Downloads folder be acceptable? You might have a look at my "cynical" (my words), pessimistic approach described on an older forum thread:

https://forum.qt.io/post/675910

I had a Progaurd file for release. Removing that fixed the problem:

keepattributes LineNumberTable,SourceFile renamesourcefileattribute SourceFile

@MrPotato On the arch wiki I'm told to build:

android-armv7a-eabi-qt5AUR - armeabi-v7a android-aarch64-qt5AUR - aarch64 android-x86-qt5AUR - x86 android-x86-64-qt5AUR - x86_64

from the AUR. But apparently the packages have been dropped. From the maintainer:

I'll drop this package, I been thinking and there are a lot of strong reasons not to waste any time maintaining it.
KDE doesn't provide an easy way to download the entire Qt source code in a single package, like in the official Qt releases.
Also, KDE doesn't provides tagged versions, I've to keep tracking manually the latest commits, or converting it to a git package.
It will require to split this package into 47x4 packages, 47 Qt modules and 4 architectures to maintain, that's 188 packages to maintain, absurd!
Cloning a git repository is slower than just downloading a source package file, making the build even much slower and painful.
Is a lot of work for something that will be dead in 1 year or 2 at most.
Good luck to the one that will step up to take care of this monstrosity, to the rest of developers, don't be lazy and consider switching to Qt6.

Which leaves me with the only alternative being to use the Qt Online Installer. I guess this must be the only option. Which is a bummer, because now I'll have duplicate packages on my system.

@Fitndex-developer said in In-App Purchasing of Registered Product (google store):

com.fitndex.theApp

Hello Everyone,

since there has been no activity on this post, I thought I'd let everyone know that this setup works with one change in the code:

do not include the app name in the identifier.

identifier: 30day_data_access ... is correct
identifier com.fitndex.theApp.30day_data_access ... is wrong

On google play I was missing the following.

I was in internal testing and the app had not been published, i published to closed testing. Add licence testers to the app in google play console (this is different than the release track email list) If using the same app version code as the published version, testing will work, even when plugged in for debug, if you are logged into the tester gmail account.

I took a crack at developing subscriptions in java, and for me, that is going to take a while but I will finish (the jni messenger example in android extras helps start with communicating with java if you are new to that), Qt purchasing makes life a lot easier just most of your work is going to be on the google play console side when dealing with Qt Purchasing. So if things are not working, check your settings with google (or apple), that is most likely it.

Qt purchasing does not handle subscriptions, it will never find your subscriptions no matter what. The reason for that is the developers could not come up with a platform independent solution for subscriptions. The community needs to figure this one out for everyone. An example anyone?

Since monetization is so important; and documentation/examples on qt purchasing are minimal, I hope this helps some of you!! I could have used something like this when I was working on it.

FITNDEX HOME now we are on track to launch this summer. You can join the beta on website.

Lets help each other get to market. The more money we all make, the better Qt will get, I promise.

Guys; May you please some help. I reached to a dead end

Never mind. I had to set the surface format version to 3.0 in main, at the top.

int main(int argc, char *argv[]) { QSurfaceFormat f; f.setVersion(3,0); QGuiApplication app(argc, argv); //... }

Modern Androids heavily restrict access to the file system, and getting file URLs is no longer allowed. I suspect you have bumped target SDK when upgrading and now you are bound by newer rules from Android: you'll have to upgrade your code to use storage providers and permissions.

Some info: https://developer.android.com/training/data-storage and https://developer.android.com/guide/topics/providers/document-provider

@dev_liya Why do you need threads to generate random numbers?!
You can do this way easier using QTimer...

I have found a solution! I did multiple things:

Used newer template files for Android from Qt/6.2.3/android_arm64_v8a/src/android/templates/ (res/values/libs.xml - overwritten, build.gradle - overwritten, AndroidManifest.xml - copy and paste and then edited the content and added the missing things from my old one) Used newer gradle files from /Qt/6.2.3/android_arm64_v8a/src/3rdparty/gradle/gradle/wrapper/ - overwritten Upgrade of Qt Creator, Qt 6.2.2 -> 6.2.3, Android SDK, Android NDK
