Error: MapFragment could not be added to android.support.v4.app.Fragment

Question

First I looked here: Start FragmentActivity from Activity , and now I have the following problem:

MapsActivity:

public class MapsActivity extends FragmentActivity { private GoogleMap mMap; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.maps); setUpMapIfNeeded(); } ... 

and want to run it from MainActivity with

 startActivity(new Intent(this, MapsActivity.class)); 

Activity registered in Android Manifest:

 <activity android:name="de.xbjoernx.gapp.MapsActivity"></activity> 

Mistake

 FATAL EXCEPTION: main java.lang.RuntimeException: Unable to start activity ComponentInfo{de.xbjoernx.gapp/de.xbjoernx.gapp.MapsActivity}: android.view.InflateException: Binary XML file line #2: Error inflating class fragment at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2308) at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2358) at android.app.ActivityThread.access$600(ActivityThread.java:153) at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1247) at android.os.Handler.dispatchMessage(Handler.java:99) at android.os.Looper.loop(Looper.java:137) at android.app.ActivityThread.main(ActivityThread.java:5227) at java.lang.reflect.Method.invokeNative(Native Method) at java.lang.reflect.Method.invoke(Method.java:511) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:795) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:562) at dalvik.system.NativeStart.main(Native Method) Caused by: android.view.InflateException: Binary XML file line #2: Error inflating class fragment at android.view.LayoutInflater.createViewFromTag(LayoutInflater.java:704) at android.view.LayoutInflater.inflate(LayoutInflater.java:466) at android.view.LayoutInflater.inflate(LayoutInflater.java:396) at android.view.LayoutInflater.inflate(LayoutInflater.java:352) at com.android.internal.policy.impl.PhoneWindow.setContentView(PhoneWindow.java:323) at android.app.Activity.setContentView(Activity.java:1881) at de.xbjoernx.gapp.MapsActivity.onCreate(MapsActivity.java:19) at android.app.Activity.performCreate(Activity.java:5104) at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1080) at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2262) ... 11 more Caused by: java.lang.ClassCastException: com.google.android.gms.maps.MapFragment cannot be cast to android.support.v4.app.Fragment at android.support.v4.app.Fragment.instantiate(Fragment.java:394) at android.support.v4.app.Fragment.instantiate(Fragment.java:369) at android.support.v4.app.FragmentActivity.onCreateView(FragmentActivity.java:272) at android.view.LayoutInflater.createViewFromTag(LayoutInflater.java:676) ... 20 more 

Any suggestions for fixing it?

Thanks, bye:)

Answer 1

as you extend FragmentActivity , which indicates that you are using the v4 support library compatible with the lower version of Android. Replace MapFragment with SupportMapFragment inside your xml file. SupportMapFragment is the one that will be used with the Android Support Package. MapFragment for the original version fragment of the version 11 API version.

Answer 2

Your mistake is the same with me, now I do not know how to fix it :))
