问题
Hey I am trying to use Google Maps on my emulator even though I've installed Google Play Services library when I run the app it says
This app won't run without Google Play Services which are missing from your phone
on LogCat I get the warning about it but not really sure why I am getting this.
my MainActivity.java
package com.mapsmaps;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.view.Menu;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.SupportMapFragment;
public class MainActivity extends FragmentActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
GoogleMap mapa = ((SupportMapFragment) getSupportFragmentManager()
.findFragmentById(R.id.map)).getMap();
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
}

"To test your app when using the Google Play services SDK, you must use The Android emulator with an AVD that runs the Google APIs platform based on Android 4.2.2 or higher."
From http://developer.android.com/google/play-services/setup.html
回答2:
To test your app when using the Google Play services SDK, you must use either:
A compatible Android device that runs Android 2.3 or higher and includes Google Play Store. The Android emulator with an AVD that runs the Google APIs platform based on Android 4.2.2 or higher.
回答3:
Please check the link http://developer.android.com/google/play-services/setup.html
there is clearly mentioned that you must provide a physical development device on which you can run and debug your app.
Note: Google Play services is not supported on the Android emulator — to develop using the APIs, you need to provide a development device such as an Android phone or tablet.
回答4:
As of now Google Maps V2 are not going to be displayed on Emulators. They will be running only on Real Time Devices which have play store app installed. Test the Application that having Google Maps V2 only on Real time device and not Emulators. There is no other alternative also as of now.
回答5:
Google Maps V2 isn't meant to work on an emulator since it is bundled with the Google Play Services.
If you're still wondering how to make it work on the emulator, you might want to give this blog post and SO answer a read. As pointed out by CommonsWare, the tweaks listed in these article boil down to pirating software. If you're really thinking about developing on Android, you might wanna consider buying a device.
回答6:
I've faced this problem before. The reason is your google play is work on your emulator. Try this to install google play to your emulator
回答7:
You can check this blog post I wrote on how to run Google Maps API V2 on the emulator:
Emulator speed-up and Google Map API V2
It is an information that I found here on SO in one of the posts.
回答8:
Start the SDK manager and install the Google API images (are currently 2). Then create an AVD based on either of them. You should be good to go :)
