Here is blog post I wrote on how to create a Map fragment in your application:
Google Maps API V2
From your code it look like your permission are not defined properly, you need to add this:
<permission android:name="com.maret.maps.permission.MAPS_RECEIVE" android:protectionLevel="signature"/>
<uses-permission android:name="com.maret.maps.permission.MAPS_RECEIVE"/>
And please add your logcat stack trace at crash moment so we could understand more clearly what the problem is.
UPDATE:
From the error you are receiving:
java.lang.RuntimeException: Unable to start activity ComponentInfo{com.maret.toilet/com.maret.toilet.MainActivity}: android.view.InflateException:
Binary XML file line #15: Error inflating class fragment
it's seems that you are not referencing the google-play-services library as needed, and this is the reason the fragment can't be inflated. the MapFragment class can't be find.
please check the guide that I posted at the beginning of the answer to see how to make the referencing correctly.
Your application tag in your manifest is missing this line
<uses-library android:name="com.google.android.maps" />
Add that and it should fix the crash
EDIT : This will only work for maps api version 1

I recently moved to MoPub and it all appears to be working well except for I have started getting this exception saying that com.millennialmedia.android.VideoPlayer can not be found. I looked and it isn't on the Millennial jar (I just got the latest from their site). Also my AndroidManifest mentions that class and Android Studio also says it can't be found.
This is what I have there:
<activity android:name="com.millennialmedia.android.MMActivity" android:theme="#android:style/Theme.Translucent.NoTitleBar" android:configChanges="keyboardHidden|orientation|keyboard" />
<activity android:name="com.millennialmedia.android.VideoPlayer" android:configChanges="keyboardHidden|orientation|keyboard" />
On Android Studio the VideoPlayer part is red.
This is the exception I got:
java.lang.RuntimeException: Unable to instantiate activity ComponentInfo{mypackage/com.millennialmedia.android.VideoPlayer}: java.lang.ClassNotFoundException: Didn't find class "com.millennialmedia.android.VideoPlayer" on path: /data/app/mypackage-1.apk

Looking at the latest Millennial Media documentation, it looks like
com.millennialmedia.android.VideoPlayer
isn't included. This may be an update that needs to be made.

my adds are import 'android.support.v4.app.Fragment
You extend Normal Activity. So you need to use import android.app.Fragment.
If you want to use Fragment from Support Library then extend FragmentActivity and use import android.support.v4.app.Fragment.
Fragment Activity is the base class for SupportBased Fragments.
I'm getting the following error trying to start an activity with a Fragment

Despite of what it says here:
Cannot be cast to android.app.Fragment
I have this error even though my Activity extends from android.support.v4.app.FragmentActivity
Unfortunately, error messages some times are very misleading. I've almost rebuilt my application to find out that during a refactor I have accidentally deleted this line o code
super.onCreate(savedInstanceState);
on the onCreate method of my activity.
I have a project that uses the GoogleMaps API, and the support library for Fragments. I have a working map in one activity already, so I know that the API and library are all set up right. I am trying to add a map in a fragment as part of a new activity.
The activity extends an android.support.v4.app.FragmentActivity, and the xml file contains:
<fragment
android:id="#+id/map"
android:layout_width="match_parent"
android:layout_height="250dp"
android:name="com.google.android.gms.maps.SupportMapFragment" />
But when I run I get the error:

All the information I can find about this error is about not having the google-play-lib properly installed both as a jar and an imported module, but I have that done - and a working map in another activity.
Any ideas?
You have to reference google play services library instead of adding jar and map_attrs.xml (and other files, like strings.xml) to your project.
If you do, you also might have deleted res/values/map_attrs.xml by accident.
I'm using ActionBarSherlock and customized style for it:
<?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">
<TextView
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:gravity="center"
android:textColor="#color/grey"
android:id="#+id/bar_title"
style="#style/Text.Medium">
</TextView>
</LinearLayout>
View mActionBarView = getLayoutInflater().inflate(R.layout.action_bar_custom, null);
getSupportActionBar().setCustomView(mActionBarView);
getSupportActionBar().setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM | ActionBar.DISPLAY_USE_LOGO | ActionBar.DISPLAY_SHOW_HOME);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
In my activity I am overriding setTitle method:
#Override
public void setTitle(CharSequence title) {
TextView txt = (TextView) findViewById(R.id.bar_title);
txt.setText(title);
}
But when in fragment I call getActivity().setTitle(), variable txt in overrided setTitle equals to null.
What's the problem?
