Error Creating Object : com.parse.ParseRequest$ParseRequestException: i/o failure

Question

I've been searching around, but none of the solution fix mine. eg: add the parseLogInterceptor, change version. I'm trying to test my apps to connect to my local Parse-server but it give me the:

com.parse.ParseRequest$ParseRequestException: i/o failure .

and thus no object is created in the database. I tried using the javascript to create object from my browser and it work seamlessly.

I running this on my Emulator and using the Android Monitor. I am using Android Studio 2.2.1.

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;

import com.parse.Parse;
import com.parse.ParseException;
import com.parse.ParseObject;
import com.parse.SaveCallback;

public class MainActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    //Parse.addParseNetworkInterceptor(new ParseLogInterceptor());

    Parse.initialize(new Parse.Configuration.Builder(this)
            .applicationId("abc123")
            .server("http://localhost:1337/parse/")
            .clientKey("")
            .build()
    );
    Log.i("ME", "DONE onCreate");

    ParseObject testObject = new ParseObject("SomeObject");
    testObject.put("foo", "bar");
    testObject.saveInBackground(new SaveCallback() {
        @Override
        public void done(ParseException e) {
            Log.v("MAIN", "PARSE ERROR:" + e);
        }
    });

}
}

and this is my app gradle:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 24
    buildToolsVersion "24.0.3"
    defaultConfig {
        applicationId "noxasch.com.testParse"
        minSdkVersion 19
        targetSdkVersion 24
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'),     'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support:appcompat-v7:24.2.1'
    testCompile 'junit:junit:4.12'
    compile 'com.parse:parse-android:1.13.0'
}

I fix this issue. If using the emulator you are suppose to use http://10.0.2.2/ instead of localhost or 127.0.0.1 to access host. developer site keep changing, i can't find the documentation, but i find it here How to connect to my http://localhost web server from Android Emulator in Eclipse
