If I did the following code, it got the error message.\r\n```\r\ntry (TextToSpeechClient textToSpeechClient = TextToSpeechClient.create()) { \r\n}\r\n\r\n/* \r\nerror message\r\njava.io.IOException: The Application Default Credentials are not available. \r\nThey are available if running in Google Compute Engine. \r\nOtherwise, the environment variable GOOGLE_APPLICATION_CREDENTIALS must be defined pointing to a file defining the credentials.\r\nSee https://developers.google.com/accounts/docs/application-default-credentials for more information.\r\n*/\r\n```\r\nSo I read the [Authentication API Keys document](https://cloud.google.com/docs/authentication/api-keys) and found API-Key not support Text-to-Speech, so I can't use api-key to Text-to-Speech Java Library.\r\n\r\nIf I want to use Text-to-Speech by API-Key or Text-to-Speech Java Library on Android. How can I do it ?\r\n\r\nThe following code is my command line and execute on mac and It work fine and can get the \"audioContent\". I think I can use http method by java.
