i got weird problem googlemap in fragment.
i implemented sort of menu items displayed via viewpager. items can show short googlemap preview. items fragments wich loaded viewpager. show previous , next items viewpager wrapped inside framelayout container (like viewpager previous , next page boundaries).
the problem map not load. last year released version eclipse , there no problem. use different mac , imported project in android studio. things worked. got error in logcat, map shows in other activity mapfragment:
e/dalvikvm﹕ not find class 'android.app.appopsmanager', referenced method com.google.android.gms.common.googleplayservicesutil.zza e/dalvikvm﹕ not find class 'android.app.appopsmanager', referenced method com.google.android.gms.common.hg.a method 1: mapview in custom fragment (android mapview in fragment) mapview shown can see grid of map. when scroll in viewpager black rectangle appears on place map has been.
<linearlayout android:id="@+id/iteminfo" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_below="@id/itemsubtitle" android:layout_centerhorizontal="true" android:orientation="vertical" > <textview android:id="@+id/itemdistanceinfo" android:layout_width="match_parent" android:layout_height="wrap_content" android:paddingbottom="0dp" android:paddingtop="0dp" android:textsize="6pt" android:textcolor="@color/white" android:text="ca. 89 km" android:visibility="gone" /> <relativelayout android:id="@+id/iteminfoprice" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerhorizontal="true" android:background="@color/white“ android:layout_margintop="8dp" android:padding="5dp" android:visibility="gone" > <include layout="@layout/price_menu_fragment"/> </relativelayout> <framelayout android:id="@+id/iteminfopicture" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerhorizontal="true" android:background="@color/white“ android:layout_margintop="8dp" android:padding="5dp" android:visibility="visible" > <imageview android:id="@+id/itemimage" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center_horizontal" android:src="@drawable/menue_info" android:visibility="invisible" /> <com.google.android.gms.maps.mapview android:id="@+id/mapview" android:layout_width="fill_parent" android:layout_height="fill_parent" /> </framelayout> </linearlayout> 
method 2: supportmapfragment in custom fragment here there black view google logo shown in left corner. scrolling in viewpager not show black rectangle in method 1.
<fragment android:id="@+id/map" android:layout_width="match_parent" android:layout_height="match_parent" class="com.google.android.gms.maps.supportmapfragment"/> i hope can me out.
