Lab 1: Build an Android App with Gradle

Part A: Setting up Android Studio on Linux

1. Download the latest version of Android Studio.
2. Unzip the file. You should get a directory named "android-studio".
3. In a terminal step into the android-studio/bin directory and run the "studio.sh" script.
4. Follow the instructions and install Android Studio. You should end up with something like this:

5. At this point you should be able to install any updates, if there are any, by clicking "Check for updates" at the bottom of the window.
6. You can now close Android Studio.

Part B: Configure your environment

1. In a terminal window, edit your .bashrc file to set your PATH and other environment variables.

export PATH=/home/$USER/android-studio/gradle/gradle-2.2.1/bin:$PATH:/home/$USER/Android/Sdk/tools:/home/$USER/Android/Sdk/platform-tools:/home/$USER/bin
export ANDROID_SDK_HOME=/home/$USER/Android/Sdk
export HISTTIMEFORMAT='%F %T '
export HISTSIZE=2000

2. You should now be able to run the gradle command without the ./ prefix. Try running this command to verify:

gradle -h

3. Unless it complains it's not executable, use the "chmod +x " command to add execute permissions to that file.
4. Try the following commands to ensure they work. If they don't then adjust your environment in step 1 or install missing software. Also read the output from the adb/android commands to get an idea of what they are used for:

   java -version
   javac -version
   adb -h
   android -h

5. We now need to create some basic source code so we can build it into an Android app. Use the mkdir command to create a source tree that looks like this (you can download the files you need here:

.
├── build.gradle
├── local.properties
└── src
    └── main
        ├── AndroidManifest.xml
        ├── java
        │   └── org
        │       └── hello
        │           └── HelloActivity.java
        └── res
            ├── layout
            │   └── hello_layout.xml
            └── values
                └── strings.xml
