Beware not to deblaterate nonsense (in this case Eclipse and OAuth Client ID) when you want to make a point. This will make you vulnerable to counter argument on details and not on what you want to convey.

Android dev used to say to go to eclipse, now it's JetBrains apparently. Have a look at the "your first app" here:
https://developer.android.com/training/basics/firstapp/index...
Compare just part of the code for making text appear:
public class MainActivity extends AppCompatActivity {
public static final String EXTRA_MESSAGE = "com.example.myfirstapp.MESSAGE";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
/** Called when the user taps the Send button */
public void sendMessage(View view) {
Intent intent = new Intent(this, DisplayMessageActivity.class);
EditText editText = (EditText) findViewById(R.id.editText);
String message = editText.getText().toString();
intent.putExtra(EXTRA_MESSAGE, message);
startActivity(intent);
}
}
All you need to do is declare which activity is the logical parent in the AndroidManifest.xml file. So open the file at app >
manifests > AndroidManifest.xml, locate the <activity> tag for DisplayMessageActivity and replace it with the following:
<activity android:name=".DisplayMessageActivity"
android:parentActivityName=".MainActivity" >
<!-- The meta-data tag is required if you support API level 15 and lower -->
<meta-data
android:name="android.support.PARENT_ACTIVITY"
android:value=".MainActivity" />
</activity>
For something exciting and interesting, I'd rather not see "paste the following XML" anywhere in the instructions.
