accessibility – Android – Preventing TalkBack to read the application Name and current Orientation

Posted by: admin June 15, 2020 Leave a comment

Questions:

Problem is I am using TTS to read a long string message when my activity is launched, but TalkBack automatically reads the application name in the middle of it and cuts the long string and is very annoying.

I would like to disable the TalkBack read the Application name every time an activity is launched. Removing its android:label attribute is not a viable solution as the application is controlled by someone else and I have no control over it.

So, Is there any API that I could call to prevent the TalkBack feature from reading the application name when an application is launched?

Any Help would be highly appreciated.

Thanks a lot in advance.

Regards,
Ashok

How to&Answers:

A solution would be to override dispatchPopulateAccessibilityEvent() in Activity to return true. This will prevent Talkback from announcing activity label.

Answer:

But this line in onCreate of Launcher Activity

Kotlin:

ViewCompat.setImportantForAccessibility(window.decorView,
ViewCompat.IMPORTANT_FOR_ACCESSIBILITY_NO)

Java:

ViewCompat.setImportantForAccessibility(getWindow().getDecorView(),
ViewCompat.IMPORTANT_FOR_ACCESSIBILITY_NO);

This worked for me.

Not that I am aware of.

Then delay your “long string message” a bit, to give time for TalkBack to do its standard announcements.

Answer:

You should add this to AndroidManifest.xml

<activity
            android:name="com.mobile.myapp.test"
            android:label="About"
            android:screenOrientation="portrait" />

Leave android:label empty if you don’t want TalkBack to read activity name.

Answer:

For Preventing TalkBack to read the application Name every time you switch activity is to set a name (label) of the Activity in Manifest:

<activity
        android:name=".pavlos.myActivity"
        android:label="Pavlos Activity" />

Adding android:name="" to Manifest will stop TalkBack announcing the name of the App every time you switch Activities.
