If there is no more detail to that log message then it means that you have not included the Google Play Services library into your APK.
You can use like this in layout.xml

so yeah
I've experienced similar issues with Map Fragments crashing my app. The way I resolved the crashing was to initialize the map fragment in Java rather than in xml. More specifically, I used a FrameLayout container in the xml for the map and handled all of the fragmentation in Java using FragmentManager.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:id="#+id/map"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
</LinearLayout>
...
import android.gms.maps;
import android.gms.maps.model;
...
MapFragment mapFrag = (MapFragment)FragmentManager.FindFragmentByTag("map");
if(mapFrag == null){
FragmentTransaction fragTran = FragmentManager.BeginTransaction();
mapFrag = MapFragment.NewInstance();
fragTran.Add(Resource.Id.map, mapFrag, "map");
fragTran.Commit();
}
GoogleMap googleMap = mapFrag.Map;
I've done this on my other apps and it worked fine. On my new app, when I run it I get a message box that says
"Unfortunately livebitcoinscharts has stopped",
The project is just from the template code generated by eclipse, I did not add anything to it
I'm using eclipse and tried putting a break point on the first line of code, which never went off.

I think this is because you are usin ActionBarActivity which is under android suuport library v7 appcompat library which has to inflate a theme under Theme.AppCompat like Theme.AppCompat.Light.DarkActionBar
You can just inherit from Activity if you don't want actionbar.

First problem MainActivity is your launcher page here but you define the secondactivity as luncher in manifest.change it first.
Add an oncreate() to secondactivity otherwise there is nothing to show when the button click.
Third change your MainActivity Context to activity which is MainActivity.this not local
Other things are fine , and hope you understand your small problems..
Change your manifest to something like this:
// MANIFEST FILE
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="18" />
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name="com.example.navigate.MainActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name = "android.intent.action.MAIN"/>
<category android:name = "android.intent.category.LAUNCHER"/>
</intent-filter>
</activity>
<activity android:name = ".SecondScreenActivity" />
</application>
And in your SecondScreenActivity add an oncreate method with the contet view like:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.secondactivity_layout);
}
And also in your mainactivity change the context to MainActivity.this . Here you define the context inside onclicklistener which links to your local method not the class.
Hi i need help with a tutorial i tried from ( http://xjaphx.wordpress.com/2012/02/04/android-xml-adventure-parsing-html-using-jsoup/ ). It's about jsoup but i can't get it to work i only get a lott of errors and stuff.

//set layout view
super.onCreate(savedInstanceState);
setContentView(R.layout.act_main);
//process
try {
((TextView)findViewById(R.id.tvDisplay)).setText(getBlogStats());
} catch (Exception ex) {
((TextView)findViewById(R.id.tvDisplay)).setText("Error");
}
}
protected String getBlogStats() throws Exception {
String result = "";
//get html document structure
Document document = Jsoup.connect(BLOG_URL).get();
//select path
Elements nodeBlogStats = document.select("div#blog-stats ul li");
//check results
if(nodeBlogStats.size() > 0) {
//get value
result = nodeBlogStats.get(0).text();
}

I would be really glad if anyone could help me. Thanks
I got it to work now. I had added the jsoup library in "External jars" as he said in the tutorial, but when I deleted it and just copied it in the "libs" map instead it worked.
you have to implement AsyncTask. I think this will help you
So I have an action bar I am trying to learn and when I implement it I see this white spinning circle left of my first menu item. Why is this being shown here?

Here is a screenshot (I cannot post images here yet)

How can I get rid of this spinning circle before I publish the app? It is an ugly and annoying distraction to the app itself.
Thanks Y'all!
Try commenting out the line requestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS); in your onCreate() callback.
