Blank Screen on map application

Postby vpachawa » Tue Sep 28, 2010 8:49 pm

Hi
I am developing a basic gps application to show the map.
But all I get is blank screen on emulator.

I am behind a proxy but internet application is working fine on emulators.
I tried generating a google maps api key and am using that.

mu manifest.xml would be:
Syntax: [ Download ] [ Hide ]
Using xml Syntax Highlighting
  1. <?xml version="1.0" encoding="utf-8"?>
  2. <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="org.prag" android:versionCode="1" android:versionName="1.0">
  3.  
  4. <application android:icon="@drawable/icon" android:label="@string/app_name">
  5. <activity android:name=".LatitLongit" android:label="@string/app_name">
  6.  
  7. <intent-filter>
  8. <action android:name="android.intent.action.MAIN" />
  9. <category android:name="android.intent.category.LAUNCHER" />
  10. </intent-filter>
  11.  
  12. </activity>
  13.  
  14. <activity android:name=".maps.MapViewExample"></activity>
  15. </application>
  16.  
  17. <uses-library android:name="com.google.android.maps" />
  18. <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
  19. <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
  20. <uses-permission android:name="android.permission.INTERNET" />
  21.  
  22. </manifest>
Parsed in 0.002 seconds, using GeSHi 1.0.8.4


and my mapview xml would be:
Syntax: [ Download ] [ Hide ]
Using xml Syntax Highlighting
  1. <?xml version="1.0" encoding="utf-8"?>
  2. <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
  3.  android:orientation="vertical"
  4.  android:layout_width="fill_parent"
  5.  android:layout_height="fill_parent"
  6.  >
  7.   <com.google.android.maps.MapView
  8.    android:id="@+id/mapView"
  9.    android:layout_width="fill_parent"
  10.    android:layout_height="fill_parent"
  11.    android:enabled="true"
  12.    android:clickable="true"
  13.    android:apiKey="0xIRsMjQ0PEIuyzI4WWrcPjYhE8e5EdyAtgcRQg"
  14.    />
  15. </LinearLayout>
  16.

my mapview java class has the following code:
Syntax: [ Download ] [ Hide ]
Using java Syntax Highlighting
  1. public class MapViewExample extends MapActivity {
  2.  
  3.         /** Called when the activity is first created. */
  4.         @Override
  5.         public void onCreate(Bundle savedInstanceState) {
  6.                 setTitle("Map View");
  7.                 super.onCreate(savedInstanceState);
  8.                 setContentView(R.layout.mapviewexample);
  9.         }
  10.  
  11.         @Override
  12.         protected boolean isRouteDisplayed() {
  13.                 return true;
  14.         }
  15.  
  16. }
  17.

Are you sure you have a working API key, for your Debug key?
