You can simulate pressing buttons even your app is closed, but you'll need Accessibility permission:

Create service extended from AccessibilityService:

class ExampleAccessService:AccessibilityService() {
    override fun onInterrupt() {
    }

    override fun onAccessibilityEvent(event: AccessibilityEvent?) {
    }
    
    fun doAction(){
        performGlobalAction(GLOBAL_ACTION_RECENTS)
//        performGlobalAction(GLOBAL_ACTION_BACK)
//        performGlobalAction(GLOBAL_ACTION_HOME)
//        performGlobalAction(GLOBAL_ACTION_NOTIFICATIONS)
//        performGlobalAction(GLOBAL_ACTION_POWER_DIALOG)
//        performGlobalAction(GLOBAL_ACTION_QUICK_SETTINGS)
//        performGlobalAction(GLOBAL_ACTION_TOGGLE_SPLIT_SCREEN)
    }
}

Call doAction() where you want action

Add to Manifest:

<application
...
    <service
        android:name=".ExampleAccessService"
        android:permission="android.permission.BIND_ACCESSIBILITY_SERVICE"
        android:label="Name of servise" // it will be viewed in Settings->Accessibility->Services
        android:enabled="true"
        android:exported="false" >
        <intent-filter>
            <action android:name="android.accessibilityservice.AccessibilityService"/>
        </intent-filter>
        <meta-data
            android:name="android.accessibilityservice"
            android:resource="@xml/accessibility_service_config"/>
    </service>
...
</application>

accessibility_service_config.xml:

<?xml version="1.0" encoding="utf-8"?>
<accessibility-service xmlns:android="http://schemas.android.com/apk/res/android"
    android:accessibilityEventTypes="typeAllMask"
    android:accessibilityFeedbackType="feedbackAllMask"
    android:accessibilityFlags="flagDefault"
    android:canRetrieveWindowContent="false"
    android:description="your description"
    android:notificationTimeout="100"
    android:packageNames="your app package, ex: ex: com.example.android"
    android:settingsActivity="your settings activity ex: com.example.android.MainActivity" />

Create a KeyEvent and publish it.

KeyEvent kdown = new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_BACK);
Activity.dispatchKeyEvent(kdown);
KeyEvent kup = new KeyEvent(KeyEvent.ACTION_UP, KeyEvent.KEYCODE_BACK);
Activity.dispatchKeyEvent(kup);

Try this your activity

public boolean onKeyDown(int keyCode, KeyEvent event)   
{
 if (keyCode == KeyEvent.KEYCODE_BACK)
 {

 }
 if (keyCode == KeyEvent.KEYCODE_HOME)
 {

 }
 if (keyCode == KeyEvent.KEYCODE_MENU)
 {

 }
 if (keyCode == KeyEvent.KEYCODE_VOLUME_UP)

Use onKeyListener for overriding the physical buttons in your device. See the doc.

The KeyEvent class have all the values for the physical buttons and on screen keyboard on your device. For Example KeyEvent.KEYCODE_HOME substitutes for the home button in the device.

Google it, you can find a lot of examples for KEYCODE events

If you test your application's specific component such as Activity so you may use InstrumentationTestCase's sendKeys()method, passing there any combination of keys. Also you can use TouchUtils to simulate tapping, dragging and clicking actions
