  1. POCannot resolve MapActivity class on Android
    text
    copied!<p>I have an application which has 11 different activities. One of these activities is an extension of MapActivity (it is a map for data visualization). To get to this activity the user must first travel through the launch activity, then 3 other activities. The code to launch the MapActivity is:</p> <pre><code>Intent i = new Intent(getBaseContext(), MapVis.class); i.putExtra("edu.uml.cs.isense.visualizations.session_list", sessions); startActivity(i); </code></pre> <p>When this is executed I get the following output from the Log:</p> <pre><code>09-01 14:36:22.389: WARN/dalvikvm(592): Class resolved by unexpected DEX: Ledu/uml/cs/isense/visualizations/MapVis;(0x44981910):0x128260 ref [Lcom/google/android/maps/MapActivity;] Lcom/google/android/maps/MapActivity;(0x44981910):0x13d330 09-01 14:36:22.389: WARN/dalvikvm(592): (Ledu/uml/cs/isense/visualizations/MapVis;

It seems that there are a lot of people having issues launching a MapActivity from other activities but there are no solutions anywhere. Does anyone have a clue? Thanks.</p>
