Installation

Qt libraries and QtCreator

In the website of Qt, download the Qt installer open-source application development. Then go to the directory where it is downloaded, make it executable and run it as root: 

chmod 777 qt-unified-linux-x64-3.0.0-online.run
sudo ./qt-unified-linux-x64-3.0.0-online.run

When the next window appears then click on skip to continue without registering: Qtinst1.png

Then choose the installation path, the default one is usually a good choice: Qtinst2.png

Make sure that the Tools and a version of the Qt libraries are selected, inside it also select the android packages: Qtinst3.png

Once the installation is finished you can add the qtcreator executable to the system PATH or link into a directory that is already in it: 

sudo ln -sf /opt/Qt/Tools/QtCreator/bin/qtcreator.sh /usr/local/bin/qtcreator


Android Tools & SDK

To install the android tools follow the next instructions (the recommended version for now is r25.2.5). The first step is to download it and decompress it: 

sudo mkdir -p /opt/android
wget https://dl.google.com/android/repository/tools_r25.2.5-linux.zip
mkdir android-sdk
cd android-sdk
unzip ../tools_r25.2.5-linux.zip

Then execute it to download the rest of the components: 

cd tools
./android

Make sure that Android SDK Platform-tools, Android SDK Build-tools and at least one of the Android API are selected:

Androidtools2.png

Then accept the license and after the installation is finish move the Android SDK to an accessible directory. 

cd ../..
sudo mv android-sdk/ /opt/android/

The next step is to install the Android NDK (version r10e is recommended by Qt). Download it, uncompress it and copy it to the same directory as the SDK with the following commands: 

wget https://dl.google.com/android/repository/android-ndk-r10e-linux-x86_64.zip
unzip android-ndk-r10e-linux-x86_64.zip
sudo mv android-ndk-r10e /opt/android/android-ndk

Integrate Android Tools in QtCreator

First install the necessary dependencies: 

sudo apt-get install libstdc++6:i386 libgcc1:i386 zlib1g:i386 libncurses5:i386 libsdl1.2debian:i386 libgl1-mesa-dev openjdk-8-jdk
