    <p>I've been beating me head against a wall with this for a few days now. I've read just about every post I can on the topic and nothing seems to get me across the finish line.</p> <p>Trying to build an app using the Google Play Services Map v2 API.</p> <p>I've got the API key, no problem.</p> <p>Here are my bits: MainActivity.java</p> <pre><code>public class MainActivity extends FragmentActivity { GoogleMap googleMap; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); int status = GooglePlayServicesUtil.isGooglePlayServicesAvailable(getBaseContext()); if ( status==ConnectionResult.SUCCESS) { SupportMapFragment supportMapFragment = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map); googleMap = supportMapFragment.getMap(); } else { int requestCode = 10; Dialog dialog = GooglePlayServicesUtil.getErrorDialog(status, this, requestCode); dialog.show(); } } @Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. getMenuInflater().inflate(R.menu.main, menu); return true; } } </code></pre> <p>activity_main.xml:</p> <pre><code>&lt;fragment xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/map" android:layout_width="wrap_content" android:layout_height="match_parent" android:name="com.google.android.gms.maps.MapFragment"/&gt; </code></pre> <p>Relevant manifest:</p> <pre><code>&lt;uses-sdk android:minSdkVersion="11" android:targetSdkVersion="17" /&gt; &lt;permission android:name="com.mcdaniel.mmm4.permission.MAPS_RECEIVE" android:protectionLevel="signature" /&gt; &lt;uses-permission android:name="com.mcdaniel.mmm4.MAPS_RECEIVE" /&gt; &lt;uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /&gt; &lt;uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" /&gt; &lt;uses-permission android:name="android.persmission.INTERNET" /&gt; &lt;uses-permission android:name="android.persmission.ACCESS_NETWORK_STATE" /&gt; &lt;uses-permission android:name="android.persmission.WRITE_EXTERNAL_STORAGE" /&gt; &lt;uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" /&gt; &lt;meta-data android:name="com.google.android.maps.v2.API_KEY" android:value="MY API KEY" /&gt; &lt;uses-feature android:glEsVersion="0x00020000" android:required="true" /&gt; </code></pre> <p>I've got past the NoClassDefFound error involving R$styleable, and ClassNotFound of the maps class, but I cannot get past this one.</p> <p>Regarding the class, I've tried a couple different implementations without luck. This one seems the most explicit. No compile warnings.</p> <p>My target is android-17 with min of android-11. I've got the library imported (with copy files option), and referenced by my project, and exported too. </p> <p>Obviously there's something I'm missing. Please help!</p> <p>Thanks, David</p>

    3. CO@JRowan No need to be afraid of exposing the key. It is [a] not usable if you don't have their signing key and [b] public value after APK hits the Google Play: nobody can stop you from installing the app, copying to computer, unzipping and seeing (but [a] is still valid).

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).
