02 - Android Studio tools - Windows - Android

Android Studio provides several tools needed in Greenspector Studio, as:

• Android Debug Bridge (ADB) and Android Asset Packaging Tool (AAPT) to establish communication between mobile device and computer

• UiAutomatorViewer allows to analyse an Android view on a connected device. These information show what Greenspector Studio sees and are useful to create automated users journeys.

• Select More actions and SDK Manager

• Choose SDK Tools and uncheck Hide Obsolete Packages

• Search for Android SDK Tools (Obsolete) 26.1.1 and confirm installation

Environment variables

Android Studio is now installed on computer. However, it’s not known by OS as environment variables: tools are launchable only in their installation folder, which isn’t practical for Greenspector Studio uses.

• In Start Menu, launch Run (hotkey Windows+R) and type %LocalAppData%

• Browse in Android and Sdk folder

We will now verify if we have every tools we need:

• Check for presence of aapt in folder build-tools/34.0.0

• Check for presence of adb in folder platform-tools

• Check for presence of uiautomatorviewer in folder tools/bin

These tools are now installed, but they are not yet ready to be executed everywhere in the system. We will add their location to the PATH to indicate to our system where they are.

• In Start Menu, launch Run again (hotkey Windows+R) and type SystemPropertiesAdvanced

• Select Environment Variables...

• In section User variables for [USER], add variables with New...

• Still in section User variables for [USER], select line Path and click on Edit...

• With New, add the following lines, one by one

%ANDROID_HOME%\build-tools\34.0.0
%ANDROID_HOME%\platform-tools
%JAVA_HOME%\bin

Verification

Once environments variables are set, new tools can be tested from everywhere:

• Open a new terminal, in Start Menu with command prompt or in Run (Windows+R) with cmd

• Test adb with the following command:

adb --version

You should see the following result:

• Test aapt with the following command:

aapt v

You should see the following result:

UIAutomatorViewer

We didn’t had directly path to UiAutomatorViewer. Indeed, this tools need a precise Java version to run. To avoid this extra installation, we will link it to integrated java installation of Android Studio via a command.

Method 1 : Get prepared file

In this method, simply get the prepared .bat file to run UiAutomatorViewer with the right Java location.

• Download and launch uiautomatorviewer.bat

UIAutomatorViewer windows should appear.

Method 2 : Create your own script

• Open a new terminal in Start Menu, by searching command prompt. You can also access to command prompt by typing cmd in Run (Windows+R)

• Try the following command:

java -Xmx1600M -Dcom.android.uiautomator.bindir="%ANDROID_HOME%\tools" -cp "%ANDROID_HOME%\tools\lib\x86_64\swt.jar";"%ANDROID_HOME%\tools\lib\*" com.android.uiautomator.UiAutomatorViewer

UiAutomatorViewer should be able to start and appears. This command is not easy to use neither to remember so we will create a shortcut.

• In Start Menu, open Notepad

• Copy the previous command line inside the file

• Click on File/Save As... and choose a location

• Change file name with uiautomatorviewer.bat: extension format .bat is important

• Try to open your new file and verify UiAutomatorViewer is correctly working
