Unable to connect with remote debugger

Hi,

You should add which version of Qt you are using and which version of Android you are running.

You should also try a less recent version of the NDK. Android folks tends to break stuff for third parties when releasing new NDKs.

See the Android Getting Started guide in Qt's documentation.

I'm using Qt 5.11.1 and I'm using hardwares running with Android 5.0 and 8.0

Thanks for the advice: I'll try with an older version of the NDK.

I followed the tips on the "Android Getting Started guide" page and I use now the NDK version 10e but I still can't launch the application on my device in debug mode.

I still get the error message: "Remote communication error. Target disconnected: no error."
and the same log

I/ActivityManager( 1809): Start proc net.essai for activity net.essai/org.qtproject.qt5.android.bindings.QtActivity: pid=15027 uid=10004 gids={50004, 9997, 3003, 1028, 1015} abi=armeabi-v7a

Did I forget something?

Thanks !

I also tried with qtcreator 4.5.2 but without more success...

Can you debug using Android Studio ?

Francky033

no. I'm using qtcreator. Is it possible to load a project at (pro file) in android studio?

SGaist

No it's not, Android Studio is dedicated to Android Java development. The proposition is to check whether their IDE can properly debug to ensure that you have everything working correctly on their side.

Francky033

If... After a test, I can debug from android studio but I miss the debug symbols...

Francky033

In the QtCreator settings, how to insert debugging symbols in the apk file?

I use the Qmake parameters:

qmake essai.pro -spec android-g++ CONFIG+=debug CONFIG+=qml_debug && /root/Android/Sdk/ndk-bundle/prebuilt/linux-x86_64/bin/make qmake_all

Thanks !
