Get Oauth Token From Web Api To Android

I'm trying to get ِِOAuth token in android from my web api. I have tested the api in Postman and it's working perfect. Screenshot for the successful call from Postman now I need

Solution 1:

In my case I using this below way to call Web Api in Android Application.

Note : I am using OkHttp library.

Create Token class

publicclassToken {
    public String access_token;
    public String token_type;
    publicint expires_in;

    publicToken(){

    }
}

Now add OkHttp library jar to your Project.

Now to get OAuth Token call this way

OkHttpClientclient=newOkHttpClient();
            Request.Builderbuilder=newRequest.Builder();
            builder.url(write your url here);
            builder.addHeader("Content-Type", "application/x-www-form-urlencoded");
            builder.addHeader("Accept", "application/json");

            FormEncodingBuilderparameters=newFormEncodingBuilder();
            parameters.add("grant_type", "password");
            parameters.add("username", edituser);
            parameters.add("password", editpassword);
            builder.post(parameters.build());

            try {
                Responseresponse= client.newCall(builder.build()).execute();
                if (response.isSuccessful()) {
                    Stringjson= response.body().string();

                }
            catch(Exception e){
              // catch Exception here
          }

finally in response you will get your Token.

Solution 2:

Late but it might help someone

Interface class

@FormUrlEncoded@POST("/Token")
    void getTokenAccess(@Field("grant_type") String grantType, @Field("username") String username, @Field("password") String password, Callback<TokenResponse> callback);

TokenResponse class

publicclassTokenResponse {
    privateString access_token,token_type,expires_in,userName;

    publicStringgetAccess_token() {
        return access_token;
    }

    publicStringgetToken_type() {
        return token_type;
    }

    publicStringgetExpires_in() {
        return expires_in;
    }

    publicStringgetUserName() {
        return userName;
    }
}

I am using retrofit 1.9.0

RestAdapteradapter=newRestAdapter.Builder()
                    .setEndpoint(ENDPOINT_URL).setLogLevel(RestAdapter.LogLevel.FULL)
                    .build();
            NetApiapi= adapter.create(NetApi.class);

            api.getTokenAccess("password", email, password, newCallback<TokenResponse>() {


                @Overridepublicvoidsuccess(TokenResponse tokenResponse, Response response) {
                    showProgress(false);
                    try{
                        MainActivity.tokenResponse = tokenResponse;
                        startActivity(newIntent(LoginActivity.this, MainActivity.class));
                    }catch (Exception e){
                        Toast.makeText(LoginActivity.this,"Unknown Error",Toast.LENGTH_LONG).show();
                        e.printStackTrace();
                    }
                }

                @Overridepublicvoidfailure(RetrofitError error) {
                    Toast.makeText(LoginActivity.this,""+error.getMessage(),Toast.LENGTH_LONG).show();
                    showProgress(false);
                }
            });
