    copied!<p>I'm trying to use the google maps feature in android. I followed the instructions at <a href="https://developers.google.com/maps/documentation/android/hello-mapview" rel="nofollow">https://developers.google.com/maps/documentation/android/hello-mapview</a>. But when I run the app, there seems to be some kind of problem. I'm not sure what it is but the app won't load. Here is the errors listed in the logcat.</p> <pre><code>07-26 02:01:01.771: ERROR/AndroidRuntime(158): ERROR: thread attach failed 07-26 02:01:06.761: ERROR/AndroidRuntime(211): Uncaught handler: thread main exiting due to uncaught exception 07-26 02:01:06.841: ERROR/AndroidRuntime(211): java.lang.RuntimeException: Unable to instantiate activity ComponentInfo{com.trainingcenter.maps/com.trainingcenter.maps.HelloGoogleMaps}: java.lang.ClassNotFoundException: com.trainingcenter.maps.HelloGoogleMaps in loader dalvik.system.PathClassLoader@43b7d958 07-26 02:01:06.841: ERROR/AndroidRuntime(211): Caused by: java.lang.ClassNotFoundException: com.trainingcenter.maps.HelloGoogleMaps in loader dalvik.system.PathClassLoader@43b7d958 07-26 02:01:06.931: ERROR/dalvikvm(211): Unable to open stack trace file '/data/anr/traces.txt': Permission denied 07-26 02:01:17.400: ERROR/AndroidRuntime(242): ERROR: thread attach failed 07-26 02:01:26.391: ERROR/ActivityThread(63): Failed to find provider info for com.google.settings 07-26 02:02:24.580: ERROR/AndroidRuntime(323): ERROR: thread attach failed 07-26 02:07:12.640: ERROR/AndroidRuntime(417): Uncaught handler: thread main exiting due to uncaught exception 07-26 02:07:12.640: ERROR/AndroidRuntime(417): java.lang.RuntimeException: Unable to instantiate activity ComponentInfo{com.trainingcenter.maps/com.trainingcenter.maps.HelloGoogleMaps}: java.lang.ClassNotFoundException: com.trainingcenter.maps.HelloGoogleMaps in loader dalvik.system.PathClassLoader@43d02ee8 07-26 02:07:12.640: ERROR/AndroidRuntime(417): Caused by: java.lang.ClassNotFoundException: com.trainingcenter.maps.HelloGoogleMaps in loader dalvik.system.PathClassLoader@43d02ee8 </code></pre> <p>Can you tell me what's wrong?
