Build Qt Android apps using the CLI

Qt comes with a quite handy IDE: Qt Creator. Sometimes we wanna automate our the builds or we wanna just use the CLI because we wanna customize more the building process. This post will illustrate the way how to build your Qt application using the command line interface on Linux.

STEP 1 – Installing dependencies

First of all we need to Download  and install the following sowftware:

a. Java

b. the Latest Android NDK (https://developer.android.com/tools/sdk/ndk/index.html#Installing)

 

c. Qt SDK

d. Android Studio bundle (which contains the Android SDK)

I’ll assume you are able to unpack tarballs and install .run files.. so I’ll go forward! In case you need help, feel free to drop a line in the comments!

STEP 2 – Setting up environment variables

Here is the list of environment variables needed by Qt tools.

export JAVA_HOME=/home/gnuton/jdk1.7.0_21

export ANDROID_HOME=/home/gnuton/Desktop/Android/SDK/android-studio/sdk

export ANDROID_NDK_ROOT = /home/gnuton/Desktop/Android/NDK/android-ndk-r9d

 

STEP 3 – Build it!!

 

cd my-qt-app

/home/gnuton/Desktop/Android/QtAndroid53Beta/5.3/android_armv7/bin/qmake && make && make install
