I’m having problems getting a MapActivity to work on 1.5r2. As far as I can
tell I’ve done everything I need to do, but what am I missing?
The Google Maps key was generated on the Google Maps website using the Debug
keystore at the location in my Android setup.
What does "Unable to resolve superclass of
Lcom/bgies/truckerphonetest/DirectionActivity;" actually mean? As far as I
can tell, the activity is setup properly.... At least it is setup exactly
the same way I have other activities setup... with the exception that it's
the only activity that has a mapView in it.
I can't run it either on my G1 or the emulator... so I assume it's something
I am doing wrong. The project setup does have the Google APIs [Android 1.5],
and the AVD for the emulator does show the target as Google APIs when I
select it.
>From my Android Manifest :
<application android:icon="@drawable/icon"
android:label="@string/app_name" android:debuggable="true">
<uses-library android:name="com.google.android.maps" />
......
<activity android:label="Directions"
android:name=".DirectionActivity"></activity>
......
</application>
<uses-sdk android:minSdkVersion="3" />
<uses-permission
android:name="android.permission.ACCESS_COARSE_LOCATION"></uses-permission>
<uses-permission
android:name="android.permission.ACCESS_FINE_LOCATION"></uses-permission>
<uses-permission
android:name="android.permission.ACCESS_NETWORK_STATE"></uses-permission>
<uses-permission
android:name="android.permission.INTERNET"></uses-permission>
The DirectionActivity java file :
public class DirectionActivity extends MapActivity implements
LocationListener
{
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.mapactivity);
.......
}
The Map Activity layout.
