Venom

Venom is a lightweight tool that simplifies testing of the process death scenario for your android application.

Why Venom?

The Android Run Time aggressively manages its resources and occasionally terminates background applications while the user is away interacting with other apps. In such a case, all the activities are destroyed along with application scope objects and background tasks.

When the user relaunches the app, the top stack activity is restored from the saved instance state. Knowing this, your applications should always present a consistent interface and be tested against the process death scenario.

Venom makes it possible to kill the app process from the notification drawer making the testing easier and more straightforward versus the traditional ways like setting the background processes limit in Developer Options or using the stop process button in Android Studio, especially for a QA team.

Setup

The setup is pretty simple:

1. Initialize the library in Application.onCreate:

val venom = Venom.createInstance(this)
venom.initialize()

2. Call start/stop whenever you need:

venom.start()
// or
venom.stop()

See the sample app for an example.

Customize the notification

Use the builder to customize the notification:

val notification = NotificationConfig.Builder(this)
    .buttonCancel(R.string.venom_notification_button_cancel_override)
    .buttonKill(getString(R.string.venom_notification_button_kill_override))
    .buttonRestart(getString(R.string.venom_notification_button_restart_override))
    .build()   
venom.initialize(notification)

Notification Permission

Android 13 has introduced a new runtime permission POST_NOTIFICATIONS which is required to display any kind of notifications including ones for foreground services. Note that this permission is required for Venom to function properly.

Venom doesn't manage the notification permission on your behalf to keep the library flexible. Please, see an example of handling that in the sample app.
