    <p>So I've tried this 3 times, and have had no luck successfully making an Android application that will communicate with Firebase. As simple as <a href="https://www.firebase.com/docs/java-quickstart.html" rel="nofollow noreferrer">the tutorial</a> makes it, I can't help but think either I or it (most likely the former) is missing something.</p> <p>The sample app I'm making simply holds a TextView that should be updated with any changes to my Firebase at <a href="https://dummy-firebase.firebaseio.com/" rel="nofollow noreferrer">https://dummy-firebase.firebaseio.com/</a> (since I can't make a public Firebase, if you'd like you can paste the URL of your own firebase to test the code). Here's a snapshot of what's on the Firebase:</p> <p><img src="https://i.stack.imgur.com/pA9Jl.png" alt="Firebase snapshot"></p> <p>Here's the onCreate of my only Activity:</p> <pre><code>@Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); Firebase f = new Firebase("https://dummy-firebase.firebaseio.com"); f.addValueEventListener(new ValueEventListener() { @Override public void onDataChange(DataSnapshot arg0) { TextView textViewSample = (TextView) findViewById(R.id.sampleTextView); textViewSample.setText(arg0.getValue(String.class)); } @Override public void onCancelled() { // TODO Auto-generated method stub } }); } </code></pre> <p>And here's the only XML file, activity_main.xml:</p> <pre><code>&lt;RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:paddingBottom="@dimen/activity_vertical_margin" android:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin" android:paddingTop="@dimen/activity_vertical_margin" tools:context=".MainActivity" &gt; &lt;TextView android:id="@+id/sampleTextView" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@string/hello_world" /&gt; </code></pre> <p></p> <p>And here's a picture of the Manifest so you can clearly see the INTERNET permission:</p> <p><img src="https://i.stack.imgur.com/7Nc1p.png" alt="enter image description here"></p> <p>Now as I change the data on the Firebase from my browser, I believe the data in the TextView should update. This isn't happening, and I have unsuccessfully tried the to put data using EditTexts and Buttons in the previous Firebase Android project attempts. </p> <p>Thanks in advance for taking the time to look over this. Because of how simple Firebase seems to set up (and was for the Javascript version) I'm truly stumped as to what I'm doing wrong!</p> <p>Thanks!!</p>

    1. COBy the way, I am running this through Eclipse on a physical 2.2 device (not an emulator) and the device internet connectivity is fine. (Tested this on both Wi-Fi and 3G). Thanks

    2. COCould you try one of the sample apps and see if they work on your device? That would let us know if there's an issue with your project or if it's an issue with the Android SDK (entirely possible, the SDK is new and in beta). You should be able to directly install https://github.com/firebase/AndroidChat/raw/master/AndroidChat.apk or https://github.com/firebase/AndroidDrawing/blob/master/AndroidDrawing.apk on your device and test them.

    3. CO@MichaelLehenbauer: I just tried both the AndroidDrawing and the AndroidChat apps from the Firebase repo on a physical 2.3.6 phone (Samsung Galaxy Ace), they do not work. No Force Close but they just don't connect.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
