I am creating an android application using google maps. here is the code:
MapFragActivity.java
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.SupportMapFragment;
public class MapFragActivity extends FragmentActivity {
private GoogleMap map;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_map_frag);
map = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map))
.getMap();
}
}
AndroidManifest.xml:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.him.mapfrag_rnd"
android:versionCode="1"

when I make some changes in MapFragActivity.java, then map is displayed. here are the changes:
package com.him.mapfrag_rnd;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import com.google.android.gms.maps.SupportMapFragment;
public class MapFragActivity extends FragmentActivity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//setContentView(R.layout.activity_map_frag);
SupportMapFragment fragment = new SupportMapFragment();
getSupportFragmentManager().beginTransaction().add(android.R.id.content, fragment).commit();
}
}
The change I have done is commented the setContentView. I have followed all the required steps and still I am getting and error. if uncomment the setContentView() then again I get the error.
Please HELP!!!
What you have to do is include a Google Play Services library to your project. Google has very good instructions here:
Also, there is a quick start which I found very useful while trying to get Google Maps v2 to work.
I have followed the Link http://www.vogella.com/tutorials/AndroidGoogleMaps/article.html
and added the google-play-services_lib library project to my application. It was working great up to yesterday. But to day i have got the exception mentioned above. It is because of the absence of google play library or my project not able to access the files from the library. I rebuilt my project but it was not succeeded. Then i rebuilt the google-play-services_lib library project but no hope. Then i tried the "build all" option in eclipse and it works fine.
I have the same error. I use Android Studio and Gradle thus there are not too many things to configure or improve. I have done almost all things but they all did not work for me. The last one works: replace entire package play-services by smaller ones. In my case:
Replace (in build.gradle file):
by:
If you are using Intellij Idea,
Note: Make sure you have not added "google-play-services_lib" project as library in "Libraries" (left panel under Modules). If you have, you can go to "Libraries and simply remove it. Google Play Library Should Not Appear In Libraries.
Note 2: You can copy the whole google-play-services_lib directory to your own project if you wish to have it in version control or similar.
I think you have to import the whole Google Play Service library to your IDE, not only the .jar
try it ;-)
Check AndroidManifest.xml file of your google-play-services_lib project. Should be:
