copied!<p>Going round in circles here i think.</p> <p>I have an activity called Locate;</p> <pre><code>public class Locate extends Activity { public static String lat; public static String lon; public static String number; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.locate); final Button buttonMaps = (Button) findViewById(R.id.ButtonMaps); buttonMaps.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { Toast.makeText(getBaseContext(), "Button Pressed", Toast.LENGTH_SHORT).show(); try { Intent i = new Intent(getBaseContext(), displayMap.class); i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); startActivity(i); } catch (ActivityNotFoundException e) { Toast.makeText(getBaseContext(), "Activity Not Found", Toast.LENGTH_SHORT).show(); } }}); // Toast.makeText(getBaseContext(), "lat: " + lat + " long: " + lon + " from: " + testname, Toast.LENGTH_LONG).show(); } </code></pre> <p>If I make the displayMap class into a normal Activity, and just have display a toast message confirming it has loaded - then it works fine.</p> <p>If i do this though;</p> <pre><code>public class displayMap extends MapActivity { /** Called when the activity is first created. */ public void onCreate() { setContentView(R.layout.displaymap); Toast.makeText(getBaseContext(), "Display Map", Toast.LENGTH_SHORT).show(); } @Override protected boolean isRouteDisplayed() { // TODO Auto-generated method stub return false; } } </code></pre> <p>Then as soon as I click the Button, I get a force close.</p> <p>I have the correct 'uses-library' tag in my manifest;</p> <pre><code><application android:icon="@drawable/icon" android:label="@string/app_name"> <uses-library android:name="com.google.android.maps" /> </code></pre> <p>I don't get what it just force closes everytime i try and load it.</p> <p>If I make this my onClick handler then it will fire up a working googlemaps/default mapview</p> <pre><code> public void onClick(View v) { Toast.makeText(getBaseContext(), "Button Pressed", Toast.LENGTH_SHORT).show(); Uri uri=Uri.parse("geo:"+Locate.lat+","+Locate.lon); StartActivity(new Intent(Intent.ACTION_VIEW, uri)); } </code></pre> <p>But that is not what I am trying to do, I want my own - so that I can add overlays etc to it. But it does prove that the permission are set correctly and that the lib is there.</p> <p>The logcat error when the app FCs is a Unexpected DEX error.</p> <p>Can anyone point in the right direction here?</p>
