Background:
I have a class which extends from AccessibilityService. Whenever a window is changed following function is called which gives me the application name of the foreground application.
@Override
public void onAccessibilityEvent(AccessibilityEvent event) {
}
Following is the configuration I set:
@Override
protected void onServiceConnected() {
super.onServiceConnected();
//Configure these here for compatibility with API 13 and below.
AccessibilityServiceInfo config = new AccessibilityServiceInfo();
config.eventTypes = AccessibilityEvent.TYPE_WINDOW_STATE_CHANGED;
config.feedbackType = AccessibilityServiceInfo.FEEDBACK_GENERIC;
if (Build.VERSION.SDK_INT >= 16) { //Just in case this helps
config.flags = AccessibilityServiceInfo.FLAG_INCLUDE_NOT_IMPORTANT_VIEWS;
}
setServiceInfo(config);
}
AccessibilityService.xml
<?xml version="1.0" encoding="utf-8"?>
<accessibility-service
xmlns:android="http://schemas.android.com/apk/res/android"
android:description="@string/accessibility_explanation"
android:accessibilityEventTypes="typeWindowStateChanged|typeAllMask"
android:accessibilityFeedbackType="feedbackSpoken|feedbackHaptic|feedbackAudible|feedbackVisual|feedbackGeneric|feedbackAllMask"
android:notificationTimeout="100" android:canRetrieveWindowContent="true" />
The Problem:
It works fine for some time, but after a day or two it suddenly stops working. It doesn't call the onAccessibilityEvent(AccessibilityEvent event) function. Although the accessibility service of this application is enabled but still it doesn't show the application name when window is changed.
May be it doesn't work if the application comes back from sleep mode? I had to reinstall the application on top of my debug build and then again it started working but for how long.
Question: How can I make sure it always return me the application name when window is changed?
