Various crashes occur when embedding the google maps component into an android application. I’m connecting to a router via wi-fi for internet access. The stand-alone google maps app seems to work fine. To re-produce, start the maps app and begin scrolling around.<\/p>\n

Will fail within a couple of minutes, occassionally on start-up (in setContentView). Most of the errors are when drawing tiles in google code. Sometimes just an Android SEGV.<\/p>\n

NOTE : I’ve tested the same app on the Android developer phone 2 (os 1.6) and it works fine.<\/p>\n

My android app is as follows:<\/p>\n

\n\n\n\n\n\nimport com.google.android.maps.MapActivity;\nimport android.os.Bundle;\n\npublic class Maps extends MapActivity {  \n  public void onCreate(Bundle savedInstanceState) {  \n    super.onCreate(savedInstanceState);  \n    setContentView(R.layout.main);   \n  }  \n  protected boolean isRouteDisplayed() { return false; }  \n }  \n<\/code><\/pre>\n
