问题描述
我知道这个问题是问了很多次。但对我来说不工作尝试了许多解决方案。所以请帮助
I know this question is asked so many times. but not working in my case tried so many solution. so help please
我mainActivity延伸内的onCreate地图活动产生这种方式。
my mainActivity extends Activity within onCreate map generates this way.
private void initilizeMap() {
if (googleMap == null) {
googleMap = ((MapFragment) getFragmentManager()
.findFragmentById(R.id.map)).getMap();
// check if map is created successfully or not
if (googleMap == null) {
Toast.makeText(getApplicationContext(),
"Sorry! unable to create maps", Toast.LENGTH_SHORT)
.show();
}
}
}
和XML的观点是
<fragment
android:id="@+id/map"
android:name="com.google.android.gms.maps.MapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent" />
支持：
<uses-sdk
android:minSdkVersion="14"
android:targetSdkVersion="21" />
错误EM获得：

<fragment
android:id="@+id/map"
class="com.google.android.gms.maps.MapFragment"
