My notes on how to deploy to Android from within Qt Creator on GNU/Linux

Prerequisites

Java

Android Studio prefers Oracle Java, which is installed as such:

sudo apt-get install python-software-properties
sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java8-installer

The alternative is to use OpenJDK:

sudo apt-get install openjdk-8-jdk

Download Android Studio

Download the Android SDK called 'Android Studio' from the download section of https://developer.android.com/studio.

Where to download Android Studio

After the file (in my case android-studio-ide-143.2915827-linux.zip) is downloaded:

  • unzip it.
  • cd android-studio
  • cd bin
  • ./studio.sh

Just choose all default settings and quit Android Studio.

Android Studio works

Download the Android NDK

Download the Android NDK from the download section of https://developer.android.com/ndk/index.html:

Download the Android NDK

  • unzip it.

Setup Qt Creator

Qt Creator Android setup

Qt Creator add Android kit

Error: JDK Required

JDK Required: 'tools.jar' seems to be not in Studio classpath.
Please ensure JAVA_HOME points to JDK rather than JRE.

JDK required error

Solution

sudo apt-get install openjdk-8-jdk

From here I found to do

sudo update-alternatives --set java /usr/local/java/jdk1.7.0_17/jre/bin/java
sudo update-alternatives --set javaws /usr/local/java/jdk1.7.0_17/jre/bin/javaws
