What nonsense? I found the google page on beacons and it says to go and deal with oauth. https://developers.google.com/beacons/proximity/get-started https://developers.google.com/beacons/proximity/get-started 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.html 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); } } Which comes along with XML like this 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> This is before trying to get radios working, beacons, etc. Just text, a button and "back". For something exciting and interesting, I'd rather not see "paste the following XML" anywhere in the instructions.
