2.  HttpClient tidak terdeteksi di Android Studio

HttpClient is not supported any more in sdk 23. You have to use URLConnection or downgrade to sdk 22 (compile 'com.android.support:appcompat-v7:22.2.0')
If you need sdk 23, add this to your gradle:

android {
    useLibrary 'org.apache.http.legacy'
}

3.  Menambahkan Google Play Service
Open the build.gradle file inside your application module directory

Add a new build rule under dependencies for the latest version of play-services. For example:

apply plugin: 'com.android.application'
    ...

    dependencies {
        compile 'com.google.android.gms:play-services:8.4.0'

Done getSupportActionBar() is used when your class extends from support library, ie AppCompatActivity or ActionBarActivity. In that case the proper way to get reference to ActionBar is protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); getSupportActionBar().setIcon(R.drawable.profile_banner_orange); } The Action Bar follows the material design guidelines and uses a Toolbar.
