Using Qt for Android (July 2017)

Installation

Qt libraries and QtCreator

https://info.qt.io/download-qt-for-application-development

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:

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

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

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:

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. 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
