How to switch from ant to gradle while qmake building command line or in a shell script

Nelson_Piquet

I use following in a shell script for building android apk from my Qt app. Following is the crux of it.

export ANDROID_SDK_ROOT=/path/To/AndroidSdk
export ANDROID_NDK_ROOT=/path/To/AndroidNdk
export ANT_HOME=/path/To/Ant
export PATH=$PATH:$ANDROID_SDK_ROOT/tools:$ANT_HOME/bin:$JAVA_HOME/bin

qmake MyQtApp.pro -spec android-g++ CONFIG+=qtquickcompiler CONFIG+=$release
make
make install INSTALL_ROOT=/path/to/some/folder
$androiddeployqt --sign MyKey.keystore gevupc --storepass somePassword --output android --verbose --input android-libMyQtApp.so-deployment-settings.json

This is of course using ant. How can I switch qmake to use gradle instead of ant ? WIth gradle I want to support auto-incremental versioning of the app

@Nelson_Piquet You need to add "--gradle" to the androiddeployqt.

An example is available at:
https://github.com/benlau/qtci/blob/master/bin/build-android-gradle-project

Moreover, in case you build apk by command line. You may consider to use this script to increase the version code:

@benlau Sorry to come back to this after a gap. I dont see a build.gradle file in your project. Is that not required ? adding --gradle kicks in gradle but it gives the follwoing error. Isnt there a sample qt project building with gradle that I can see ? there must be so many

Getting following error with gradle :

A problem occurred configuring root project 'android-build'.

Could not resolve all dependencies for configuration ':classpath'.
Could not resolve com.android.tools.build:gradle:1.1.0.

@Nelson_Piquet My link is an example script to show how to build androiddeployqt with gradle.

androiddeployqt --input $JSON --output `pwd`/android-build --deployment bundled --android-platform android-18 --gradle --no-gdbserver $DEPLOY_ARGS

I don't know how to solve your problem but you may try this example project:
