I have created Android App successfully. But when i am deploying the app, the icon set as default. How can i change the default icon to custom in CMake?

Hi,

You need to create the template files like describe here and then edit the AndroidManifest.xml file to set the icon. If memory serves well, Qt Creator has an editor for that file that allows to do some of the setup through it rather than edit the file directly.

What exactly did you do ?

@SGaist Please see steps below.

Created Qt android project in CMake and build in release mode.
Created a folder named "android" in project folder (Where CMakeLists.txt file exist)
Copied "AndroidManifest.xml" from "android-build" folder and paste it to "android" folder which already created in step 2.
Open Projects option Qt , and under "Build Android APK" option selected "Create Templates" and edited "AndroidManifest.xml" (Added icon)
Build again and deployed. The icon not updated.!

Please see my edited "AndroidManifest.xml" file below.

Check the xml file in the build folder to see if it has changed. If not, delete the build folder and start anew.

@SGaist I checked "AndroidManifest.xml" file in the build folder, it is not changed. "AndroidManifest.xml" file in the build folder will update everytime when we building. So if i modified the file, it will not reflect in the build apk.

It's not that one that you have to change. It's the one you copied into your sources. It should then be used when building your application.

@SGaist I could not set the modified "AndroidManifest.xml" path which should be used when building your application. How can i set through "CMakeLists.txt" file?

Did you already do what is described here ?

Akshai · wrote on 2 Nov 2022, 18:55

@SGaist Yes i did it in the way. But no result. Please see my attached screenshot.

SGaist · 2 Nov 2022, 19:46

Which version of Qt are you using ?

Akshai · S SGaist 2 Nov 2022, 19:38

@SGaist Latest one.

SGaist · 2 Nov 2022, 19:56

That's Qt Creator. I am asking which version you use to build your application.

Akshai · S SGaist 2 Nov 2022, 19:47

@SGaist This one.

SGaist · 2 Nov 2022, 20:22

So you put your Androïd related changes in the else clause that concerns Qt 5.

Akshai · S SGaist 2 Nov 2022, 19:59

@SGaist What to do? please guide me.

SGaist · 2 Nov 2022, 20:36

Move your changes to the Qt 6 part of the if.

Akshai · 3 Nov 2022, 10:09

@SGaist Done as mentioned. But there is no change found. Please see screenshot.

Remember to do a full rebuild (clean, run cmake, rebuild) when you change cmake code.
