Hi Kool!
Do you see any lines related to Facebook in the Application or Compile Output?
Please also make sure that your build.gradle correctly links the Facebook framework in the dependencies section with the line
dependencies {
compile 'net.vplay.plugins:plugin-facebook:2.+'
}
In order to correctly link and build the project with the configured plugin frameworks, please also see if “Use Gradle” is activated for the Android Build Kit in the “Projects” tab on the left side of Qt Creator.
You can also configure Gradle as default build system for Android in the Qt Creator Options:
Devices – Android – “Use Gradle Instead of Ant”
Let me know if this helps!
Note: After activating Gradle, please make sure to remove any previous installations on your device, as well as the build folder on your file system to make sure you get a fresh and clean build with Gradle.
Best,
Günther
