Why my android app crashes with “Unfortunately myapp stopped” error?

[ndutgd4]

I am still learning the android apps development and after I started making a very simple app with google maps api v2 (not using it yet) when i run it on my Sony Xperia SL it says "Unfortunately myapp stopped". The red msg's in the LogCat are "Can't open file for reading" (twice).MainMenu.java\[code\]public class MainMenu extends Activity {@Overrideprotected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main_menu); Button bntStart = (Button) findViewById(R.id.buttonStart);}@Overridepublic boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. getMenuInflater().inflate(1, menu); return true;}}\[/code\]MainActivity.java\[code\]public class MainActivity extends Activity {@Overrideprotected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main);}@Overridepublic boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. getMenuInflater().inflate(R.menu.activity_main, menu); return true;}}\[/code\]activity_main_menu.xml\[code\]<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"android:layout_width="match_parent"android:layout_height="match_parent"android:background="@drawable/menu_bg"android:gravity="center_vertical"androidrientation="vertical" ><LinearLayout android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center" > <Button android:id="@+id/buttonStart" android:layout_width="80dp" android:layout_height="wrap_content" android:layout_gravity="center" android:layout_margin="5dp" android:text="Start" /> <Button android:id="@+id/buttonStop" android:layout_width="80dp" android:layout_height="wrap_content" android:layout_gravity="center" android:layout_margin="5dp" android:text="Stop" /></LinearLayout><Button android:id="@+id/buttonExit" android:layout_width="80dp" android:layout_height="wrap_content" android:layout_gravity="center" android:layout_margin="5dp" android:text="Exit" /></LinearLayout>\[/code\]activity_main.xml\[code\]<?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"xmlns:tools="http://schemas.android.com/tools"android:layout_width="match_parent"android:layout_height="match_parent"tools:context=".MainActivity" ><fragment xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/map" android:layout_width="match_parent" android:layout_height="match_parent" class="com.google.android.gms.maps.MapFragment" /></RelativeLayout>\[/code\]manifest\[code\]<?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android"package="taxi.route"android:versionCode="1"android:versionName="1.0" ><uses-sdk android:minSdkVersion="11" android:targetSdkVersion="16" /><permission android:name="taxi.route.permission.MAPS_RECEIVE" androidrotectionLevel="signature" /><uses-permission android:name="taxi.route.permission.MAPS_RECEIVE" /><uses-permission android:name="android.permission.INTERNET" /><uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /><uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" /><uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" /><uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /><uses-feature android:glEsVersion="0x00020000" android:required="true" /><application android:allowBackup="true" android:icon="@drawable/ic_launcher" android:label="@string/app_name" android:theme="@style/AppTheme" > <activity android:name="taxi.route.MainMenu" android:label="@string/app_name" > <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <meta-data android:name="com.google.android.maps.v2.API_KEY" android:value="http://stackoverflow.com/questions/14425726/AIzaSyCwPOMQ3LaE81JN3wdY6DvUi7EIJdn0q-I" /> <activity android:name="taxi.route.MainActivity" android:label="activity_main" > </activity></application></manifest>\[/code\]stack trace (i am not sure if thats the thingy)\[code\]01-20 17:48:32.129: D/dalvikvm(663): Late-enabling CheckJNI01-20 17:48:32.399: D/TextLayoutCache(663): Using debug level: 0 -
