I'm having trouble with ttsvariable . It becomes null, even if the Text to speech object has been initialized.



Inside ShowLabel() function, I want to use tts for texts of firstObject variable. ShowLabel() function receives a List<> of FirebaseVisionImageLabel objects. I'm facing problem on speaking the text inside ShowLabel(). Though the console logs the Boolean to true and the speak() inside OnInit() work.



I have set a checker ttsIsInitialized which is Boolean type, so it needs to be true before the speak() on showLabel() runs. But it gives me null. Any help would be great. If there is a best way to do this, please tell me.



So, For now my issue is tts inside Showlabel() always becomes null. Can someone point out where's my mistake?

  • @TejasPandya I'm not sure. Is there any way to see if it executes first? is it possible to delay the override function?

  • Hi Ted! can you provide the logcat? Also, which code are you receiving from the listener? Finally, When are you executing showLabel() method? My guess is, since the API is asynchronous (synchronous APIs don't need listeners), you are executing the method before the listener is called, but since the listener is executed at some point, you see both the tts member as null, and the correct logs. Try executing showLabel inside the success block of onInit (AKA the listener)
