I have been trying to extend FragmentActivity. The same app works if I extend the MainActivity class to Activity and import necessary packages for a normal Activity.
The basic need is that i cannot access the map in a normal activity. It needs to extend FragmentActivity to run the following line.
googleMap= ((SupportMapFragment)getSupportFragmentManager().findFragmentById(R.id.map)).getMap();
Here is the Java code
package com.dacoders.locationtodo;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.view.Menu;
public class MainActivity extends FragmentActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
Here is the layout XML
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:name="com.google.android.gms.maps.MapFragment"/>
Here is the AndroidManifest.xml

Here is the layout XML
<fragment
I'm not sure if you can have a fragment as the root of your layout as fragments are supposed to be pieces that are put in another layout and exchanged.
Have you tried putting your fragment in a FrameLayout and see if it still crashes?
Your min sdk is 11. I guess you can make it 12 and use MapFragment.
To know why check the link http://developer.android.com/about/dashboards/index.html.
In that case (minsdk is 12 or above) you can extend Activity
GoogleMap mMap = ((MapFragment) getFragmentManager().findFragmentById(R.id.map))
.getMap();
Also import
import com.google.android.gms.maps.MapFragment;
Or
You should use Support Fragment.
<fragment
class="com.google.android.gms.maps.SupportMapFragment"
android:id="#+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
Your activity must extend FragmentActivity
SupportMapFragment fm = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);
GoogleMap mMap = fm.getMap();
Make sure you have added support library
Also make sure you imported the below
import android.support.v4.app.FragmentActivity;
import com.google.android.gms.maps.SupportMapFragment;

Hi I have an activity that shows a dialog form an standard layout.
android:theme="#android:style/Theme.Holo.Light.Dialog"/>
I was trying to add a simple spinner to the actionbar but I am having issues and error in the line getActionBar().setNavigationMode(ActionBar.NAVIGATION_MODE_LIST).
When I change my theme to a common activity it works perfect.
This are the errors showed by the logcat:

I am working on an Android Project of using goolge map.
But when I try to run it on a tablet or HTC phone, it says the application has stopped unexpectedly. What kind of setting do I need to do, like adding library files and etc.
I have used my API key as well, so if this apps runs on a device, can I view the map or only the grid? what do we mean by signing the app?

Not sure if you just failed to paste it in but it appears your layout is missing this at the top.

Regardless check this link out:
What is 'android.security.MessageDigest''?
Ive recently generated a new api key for an android application and now it keeps crashing whenever i try to use part of the app that uses google maps.
does anybody know what the problem could be?
ive not changed any code at all it was working flawlessly before i updated the api key.
Thanks.

Update:
ok it seems to be a problem with the location manager (returning null) :
locMan = (LocationManager) getSystemService(LOCATION_SERVICE);
Criteria criteria = new Criteria();
provider = locMan.getBestProvider(criteria, false);
loc = locMan.getLastKnownLocation(provider);
Manifest
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" />
<uses-permission android:name="android.permission.GET_ACCOUNTS" />

<uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" />
<uses-permission android:name="android.permission.VIBRATE" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
ok its definitely my locationmanager not getting my location.
any help would be greatly appreciated. im stressing.
Can you see grids in the MapView.If yes then may be you are not getting the location.But if you are not getting that as well and your application crashes,check your manifest for the following
<uses-library android:name=”com.google.android.maps” />
getLastKnownLocation can often return null. You should be using requestLocationUpdates in that case.
