How to use Google Maps API v2 with API level 10?

Question

According to 1 the code posted there can be used for Android API 12 or later. I tried the code on an emulator having API level 10 (Google API platform 2.3.3) and I get the following famous error:

E/AndroidRuntime( 429): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example..../com.example....MainActivity}: android.view.InflateException: Binary XML file line #7: Error inflating class fragment

I copy-paste my .xml file below.

<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" >

<fragment xmlns:android="http://schemas.android.com/apk/res/android"
  android:id="@+id/map"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  class="com.google.android.gms.maps.MapFragment"/>

So I assume the fragment element is not supported...(?). I tried the same code in an emulator with API level 17 and I get that message (which as I am reading is currently an issue of the emulator):

This app won't run unless you update Google Play Services.

I do not have a real device having level 17 to test it, but I assume that it might work.

Do I have any mistake in the above code specifically for level 10? What is the code currently supported by Google, in order to develop maps in an android device with API level 10?

UPDATE: After changing to FragmentActivity and SupportMapFragment I get the following:

W/dalvikvm( 6718): Unable to resolve superclass of Lmaps/a/du; (406)
W/dalvikvm( 6718): Link of class 'Lmaps/a/du;' failed

And after 2 seconds:
Google Maps Android API Authorization failure

UPDATE 2: I changed the project to build target for android 10 (I had it for android 4.2). So now I do not see the authorization failure). I also paste my api accesses from google .

I do not have proguard enabled in my .properties of the project ie,:
# To enable ProGuard to shrink and obfuscate your code, uncomment this (available properties: sdk.dir, user.home): #proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt

# Project target.
target=android-10
android.library.reference.1=../../adt-bundle-windows-x86/sdk/extras/google/google_play_services/libproject/google-play-services_lib

The problem still remains:

Answer 1

而不是使用com.google.android.gms.maps.MapFragment使用com.google.android.gms.maps.SupportMapFragment ，对于Activity它必须切换为FragmentActivity如下面的评论中所述

Answer 2

i use below code hope use full to you:-

packages and extend

import android.support.v4.app.FragmentActivity;
import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.SupportMapFragment;
import com.google.android.gms.maps.model.BitmapDescriptorFactory;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.MarkerOptions;

public class UserLocation extends FragmentActivity 

code

    android.support.v4.app.FragmentManager fragmentManager = getSupportFragmentManager();
    SupportMapFragment mapFragment = (SupportMapFragment) fragmentManager
            .findFragmentById(R.id.map);
    googleMap = mapFragment.getMap();

works for me.

SupportMapFragment

http://developer.android.com/reference/com/google/android/gms/maps/SupportMapFragment.html

Answer 3

For earlier APIs, you need to use SupportmapFragment . See the SupportMapFragment docs , Basically use class="com.google.android.gms.maps.SupportMapFragment" instead of class="com.google.android.gms.maps.MapFragment"

Answer 4

{ Use this as a Reference for codes.. http://www.androidhive.info/2013/08/android-working-with-google-maps-v2/

also in the above example one has to use his own Api Key in metadata tag of manifest instructions for generating Api key are given }

now if you want to implement this code in android 2.3

---

1)first change the Manifest

<uses-sdk
    android:minSdkVersion="10"
    android:targetSdkVersion="17" />

then Rightclick>Properties>Android>Android 2.3

---

2)there are two google play service libraries

   a)..\sdk\extras\google\google_play_services_froyo\libproject\google-play-services_lib

   b)..\sdk\extras\google\google_play_services\libproject\google-play-services_lib

if you'r working on android 2.3 try having the first one a as a library project (you will first need to import it as a library project File>import>................)

---

3)then follow instructions here

---

4)see to it that your Google play services app is up to date on your device
