Wait for Android Emulator

The Wait for Android Emulator step waits for the Android Emulator to boot. You must use this step before running any UI tests.

For additional details, please refer to the Emulator documentation.


Ensure that you select the Intel Pool in the Configuration tab, as the Wait for Android Emulator step will not function in the M1 Pool. Please refer to this documentation for selecting a pool in Configuration.


The workflow steps that need to be executed before running the Wait for Android Emulator workflow step, along with their respective reasons, are listed in the table below.

Prerequisite Workflow StepDescription
Android BuildThis step is necessary to obtain the Android outputs required for processing. Without adding this step beforehand, the Wait for Android Emulator step will still function, but the app will not be installed.
Android SignIf you intend to use a signed app, this step must be executed beforehand to process the output. Failure to add this step beforehand will result in the Wait for Android Emulator step still functioning, but since the app is not signed, there may be installation issues. If your app is already signed, you can skip this step.

If a step other than the Android Build or Android Sign step is used to build or sign the app, then the Wait for Android Emulator step depends on this step.

$AC_TEST_ADB_ARGUMENTSADB arguments for the device. For additional details about ADB arguments, please refer to the Android Debug Bridge documentation. The default value is: -no-window -no-audio -no-boot-anim -netdelay none -no-snapshot -wipe-data -gpu auto. You may add new arguments, but don't change the default ones, such as no-window.Required
$AC_SIGNED_APK_PATHThe optional full path of the signed APK file to install after the emulator boots. If this step runs after the Android Sign step, the variable will be automatically populated.
