问题
I'm trying to connect to one of my endpoint methods from an android client to my locally running app engine backend. The problem is I'm getting a SSLHandshakeException. My API is not protected by OAuth. The method I am trying to reach looks like this:
@ApiMethod(name = "register")
public UserInfo registerUser(UserInfo userInfo) {
try {
checkUserParameters(userInfo);
ofy().save().entity(userInfo).now();
return ofy().load().entity(userInfo).now();
} catch (InvalidPropertiesFormatException e) {
logger.info(e.getMessage());
return null;
}
}
And from my client I am doing this:
if (regService == null) {
UserInfoApi.Builder builder = new UserInfoApi.Builder(AndroidHttp.newCompatibleTransport(),
new AndroidJsonFactory(), null)
.setRootUrl(LoginActivity.LOCALHOST_IP)
.setGoogleClientRequestInitializer(new GoogleClientRequestInitializer() {
@Override
public void initialize(AbstractGoogleClientRequest<?> abstractGoogleClientRequest)
throws IOException {
abstractGoogleClientRequest.setDisableGZipContent(true);
}
});
regService = builder.build();
UserInfo userInfo = new UserInfo();
userInfo.setGcmId(registerToGcm());
userInfo.setAccountName(params[0]);
userInfo.setEmail(params[0]);
userInfo.setProfilePictureUrl(null);
UserInfo userInfo = regService.register(userInfo).execute();
}
For some reason this does not work, I have also tried with the API that you get when importing the backend module to android studio but it gives the same error.

So... The problem was I was using https instead of http when setting rootUrl on the client.
