我在Android中使用Google语音客户端库，参考链接为： - https://cloud.google.com/speech/docs/reference/libraries#client-libraries-install-java
I have also executed this command(export GOOGLE_APPLICATION_CREDENTIALS="/Users/Downloads/service-account-file.json") in my Mac os
After executing the whole code I am getting this error --> The Application Default Credentials are not available. They are available if running in Google Compute Engine. Otherwise, the environment variable GOOGLE_APPLICATION_CREDENTIALS must be defined pointing to a file defining the credentials.
