I use Google Cloud Speech API(StreamingRecognize via gRPC) for speech recognizing in my app. I got the problem with authenticate on Android devices API level < 23.

Status{code=UNAUTHENTICATED, description=null, cause=java.io.IOException: Error getting access token for service account: }
I don't get this error everytime, but only on specific case. I have two activity. Let's name A and B.
Activity A has a button, which starts Activity B. Activity B communicates with Google Cloud Speech API and show results in TextView.
I get this error after following steps(on Samsung GT-P5110 (Android 4.2.2)):
// In first time everything is Okay. I receive result from server and show this.
Close Activity B (press Back Button or call onBackPressed or finish).
Press button to start Activity B.
// In this moment I get error, which was show above.
I get this error on Lenovo A1000 (API 5.0.1) and Xiaomi Mi4c (5.0.1) after:
Start Activity A -> press Button to start Activity B.
Close Activity B (press Back Button or call onBackPressed or finish).
Press button to start Activity B.
// Everything is Okay
Close Activity B (press Back Button or call onBackPressed or finish).
Minimize app .
After 5-6 or more minutes go back to Activity A.
Start Activity B.
// In this moment I always get this error.
After restart application everything is Okay, but error appears after reopen Activity B.
Who knows how I can solve this problem?
I use Play Services Dynamic Security Provider (It is required for gRPC). I installed last version Google Play Services (9.6.83). It doesn't resolve the problem.
I create ManagedChannel by following code:
GoogleCredentials creds = GoogleCredentials.fromStream(credentials);
creds = creds.createScoped(OAUTH2_SCOPES);
OkHttpChannelProvider provider = new OkHttpChannelProvider();
OkHttpChannelBuilder builder = provider.builderForAddress(host, port);
ManagedChannel channel = builder.intercept(new ClientAuthInterceptor(creds, Executors
.newSingleThreadExecutor
()))
.build();
private static final List<String> OAUTH2_SCOPES =
Arrays.asList("https://www.googleapis.com/auth/cloud-platform");
Create SpeechGrpc.SpeechStub :
SpeechGrpc.SpeechStub mSpeechClient = SpeechGrpc.newStub(channel);

thank you for your time :)
I reported this issue in the forum.
The problem occurs because you are embedding your Service Account credentials in the application. After a period of time, when the token that is created is internally refreshed, the error is thrown from:
com.google.auth.oauth2.ServiceAccountCredentials.refreshAccessToken link
In production, you will supply the access token from your server and therefore be able to instantiate the GoogleCredentials as so:
final GoogleCredentials googleCredentials = new GoogleCredentials(accessToken) {
@Override
public AccessToken refreshAccessToken() throws IOException {
return accessToken;
}
}.createScoped(OAUTH2_SCOPES);
This will prevent the error from being thrown.
