@JKSH Yes I did. On QT part, we followed a lot of techniques mentioned in that post. Using Loaders for lazy loading, optimizing images, using qtquickcompiler. The major challenge is on the OS boot time that we are working on.

Here is the link to the corresponding thread on the mailing list.

@Bremenpl there is a known issue for the androideployqt tool to scan QML imports across all qml files and add them to the APK. Add all imports to the main qml file to let the androideployqt discover them. Maybe this is also the case here. Regarding the warnings. About what warnings are you talking? At least those: /data/app/org.qtproject.example.ntm_client_win32-1/lib/x86/libQt5Network.so: unsupported flags DT_FLAGS_1=0x81 can be ignored (QTBUG-57909)

For you to debug with just only QtMultimedia set this variable environment: export QT_LOGGING_RULES=qt.multimedia.*=true Why you not use PySide2? It practical and efficient install with virtualenv and pip3. I belive there are missing libraries as Gstreamer, in this case. Cleiton Bueno Blog | Linkedin | B2Open

Thank you for reply @jsulm :) Actually i am working on Ubuntu mate (Linux) and i have rotated the screen also but, in Ubuntu mate OS screen is rotates onlu 180 degree only (Just like mirror image). it is not getting rotate +90 degree or -90 degree. Is there any other option to rotate?????

I solved by closing my db connexion with this instruction : dbCnx.removeDatabase (dbCnx.connectionName ());

Thanks for the tip, I will keep that in mind. @aha_1980 said in Application not working in release mode on Android: Have you changed anything on your computer? Updated Qt, Qt Creator or Android NDK or SDK? Well, yes I have reinstalled Qt on my Linux machine and installed Android Studio (for SDK and NDK). However, as I mentioned in the bug report I have tried to run the application from a fresh install of Qt on Windows and experienced the same issue.

I find the solution, hope that help some one. void Handler_Transaction::saveObject(bool modeThread) { if(modeThread == true) { //****************************************************** // it work for me QtConcurrent::run( this{ this->saveObject(false);}); ); return; } //doing script of thread here // }

Hi @SGaist , Yeah i just need to look into it a little bit better and do some research. After i get the class working i will try to integrate it, but this radio system is kinda low on my priority list, so i will come back with a solution when i have the time. I will mark this as solved and start a new thread when i have the class made for integration. Thanks, Izba

Alright, I found the error: In the TextEdit {} I had inputMethodHints: Qt.ImhNoPredictiveText because in earlier tests, sending emojis to TextEdit crashed the app. But with PredictiveText disabled, all fancy input methods and hence the different keyboards don't work. Also, Emojis are no problem anymore and animated Gifs are disabled.

@Joao-Alysson said in thanks: Re: icon android apk Hi @Joao-Alysson, please reply in the original thread. Please don't start a new thread just to say "thanks", and please don't delete the original thread.

Hi and welcome to devnet, What version of Qt are you using ? What version of Android is proving problematic ? Did you test that on different versions of Android ? Did you test that on different device with the same version of Android ?

@Joao-Alysson If your issue is solved, please close this topic as SOLVED too. Thanks! Regards

What device are you targeting ?

Hi, Did you already saw that KDAB's blog about barcode scanning ?

Thanks for the reply, I will check. Anyway XCB GLX on should be enougth for use OpenGL acceleration, basing on the output log.
