Hi!
I wrote a small app and tried to deploy it to my Android phone running Android 12(S). When the application starts it crashes immediately with the following error:

PID: 3356 SIG: 9I tried to deploy this from my Mac as well as from my Linux workstation. The error is always the same.
When I deploy the same app to an Android emulator it works perfect. Does anybody know what I did wrong?
BTW: The app compiles and run successful on Linux and MacOS. I could even run it with WEBAssembly.

@JoeCFD Thanks for your reply.
In the meantime I found my error. It was the file android/res/values/libs.xml. After putting there the template, the error changed:I heosys.theatin: Late-enabling -Xcheck:jni E USNET : USNET: appName: org.qtproject.theosys.theating D ProcessState: Binder ioctl to enable oneway spam detection failed: Invalid argument D ActivityThread: setConscryptValidator D ActivityThread: setConscryptValidator - put I ActivityThread: Relaunch all activities: onCoreSettingsChange D ActivityThread: handleBindApplication()++ app=org.qtproject.theosys.theating D CompatibilityChangeReporter: Compat change id reported: 171979766; UID 10619; state: ENABLED V GraphicsEnvironment: ANGLE Developer option for 'org.qtproject.theosys.theating' set to: 'default' V GraphicsEnvironment: App is not on the allowlist for updatable production driver.

@TheoSys said in Qt6.7 Android: On app start crash with missing Java function:
monotonic_buffer_resource
C++ std::pmr::monotonic_buffer_resource is not available for libQt6Core_arm64-v8a.so.
https://en.cppreference.com/w/cpp/memory/monotonic_buffer_resource
ldd /lib/arm64/libQt6Core_arm64-v8a.so to check its dependencies and add the miss lib to your build -
I had the same problem upgrading from 6.6 to 6.7, I resolved it by using the correct NDK (26.1.10909125), see https://doc.qt.io/qt-6/android-getting-started.html
