问题:

i have problem with this line when I create project which use Google maps API v2.

GoogleMap map = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)) .getMap();

It's says that I need to set minSDK to be minimum 11, but I want to use this application also on devices with android minSDK 8 (2.3.3). Any ideas? Or simply: How I can set google maps API v2 to be compatible with devices with minSDK 8.

Thanks

回答1:

Use SupportMapFragment from a FragmentActivity, instead of MapFragment from an Activity. To use fragments on devices older than API Level 11, you need to use the Android Support package's backport of fragments (where FragmentActivity comes from).

<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" >      <TextView         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:layout_centerHorizontal="true"         android:layout_centerVertical="true"         android:text="@string/hello_world" />     <fragment         android:id="@+id/map"         android:layout_width="match_parent"         android:layout_height="match_parent"         class="com.google.android.gms.maps.SupportMapFragment"/>  </RelativeLayout>

AND:

package de.meinprospekt.android.ui;  import java.text.SimpleDateFormat;  public class MainActivity extends FragmentActivity {      @Override     protected void onCreate(Bundle savedInstanceState) {         super.onCreate(savedInstanceState);         setContentView(R.layout.activity_main);     }  }

    Fragment fragment = getSupportFragmentManager().findFragmentById(             R.id.map);     SupportMapFragment mapFragment = (SupportMapFragment) fragment;     GoogleMap mMap = mapFragment.getMap();
