Register new customer through Android REST client

[Grig]

Hey, guys!!

Developed an Android app for Magento store, but not able to register new customer with call to Magento's REST API.

I'm passing this json formatted string within POST request body:

{
"customer": {
"email": "mailg@gmail.com",
"firstname": "string_first",
"lastname": "string_last"
},
"password": "stringUI532pass"
}

and getting this error log:

{"message":"Decoding error: \nDecoding failed: Syntax error\n#0 \/home\/mohame ...

though Magento is able to decode, when i'm passing same string through postman.

Using Retrofit rest client in Android app.

These are some examples, passed from app:

String t = "{" +
        "  'customer': {" +
        "    'email': 'mailg@gmail.com'," +
        "    'firstname': 'string_first'," +
        "    'lastname': 'string_last'" +
        "  }," +
        "    password': 'stringUI532pass'" +
        "}";

String t2 = "{\n" +
        "  \"customer\": {\n" +
        "    \"email\": \"mailg@gmail.com\",\n" +
        "    \"firstname\": \"string_first\",\n" +
        "    \"lastname\": \"string_last\"\n" +
        "  },\n" +
        "    \"password\": \"stringUI532pass\"\n" +
        "}";

... and many more of them ))

Any suggestions??

Just curious, is there anybody, who uses rest api calls from Android app??
