问题
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"
android:versionName="1.0" >

</manifest>

android:id="@+id/map"
android:name="com.google.android.gms.maps.SupportMapFragment"

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!!!
回答1:
What you have to do is include a Google Play Services library to your project. Google has very good instructions here:
- http://developer.android.com/google/play-services/setup.html
Also, there is a quick start which I found very useful while trying to get Google Maps v2 to work.
- https://docs.google.com/document/pub?id=19nQzvKP-CVLd7_VrpwnHfl-AE9fjbJySowONZZtNHzw

If you are using Intellij Idea,
- Select your project from project panel
- Hit F4 in order to open the project structure window
- Select Modules from left panel, then hit + button then select "import module" and navigate to "ANDROID-SDK"/extras/google/google_play_services/libproject/google-play-services_lib. By doing this this project will be added to Modules alongside with your project
- Select your project, then select "Dependencies" (it's a Tab) from right panel. Click + button then "3 Module dependencies..." and select "google-play-services_lib".
- Click + button again then "1 jars or directories..." and navigate to "/libs" folder in the above path and select "google-play-services.jar".
- Click ok and close project structure window.
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.
回答3:
I think you have to import the whole Google Play Service library to your IDE, not only the .jar
try it ;-)
回答4:
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):
compile 'com.google.android.gms:play-services:8.4.0'
by:
// Google Cloud Messaging
compile 'com.google.android.gms:play-services-gcm:8.4.0'
// Google Location
compile 'com.google.android.gms:play-services-location:8.4.0'
回答5:
I solved the issue by first checking the play services lib is added correctly and adding this data in manifest file under application tag <meta-data
android:name="com.google.android.gms.version"
android:value="@integer/google_play_services_version" />
回答6:
i have also got this error in android studio and i had already included play services alpha 3 with gradle alpha5, what i did wrong was i have included multidex.
in gradle
multiDexEnabled true
and in Application class's onCreate
MultiDex.install(this);
but i forgot to extends Application class with MultiDexApplication
because MultiDexApplication has not been extended so that it can't include gms and any other dex classes so it's giving error at starting of gms String.
Hope this helps
回答7:
Check AndroidManifest.xml file of your google-play-services_lib project. Should be:
package="com.google.android.gms"
回答8:
Use Android SDK Manager download "google play services"
import it into your workspace (path: android-sdk root/extras/google/google_play_service/libproject/google-play-service_lib)
project Properties -> android -> Library add google-play-service_lib
Build path -> Order and Export check Android private libraries
回答9:
I solved this error by checking "Copy projects into workspace" while importing the Google Play Services lib.
More info here: http://developer.android.com/google/play-services/setup.html
回答10:
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.
回答11:
If you are using split Google Play Services (see here : https://developers.google.com/android/guides/setup#split)
You must include the base play services to your gradle file:
compile 'com.google.android.gms:play-services-base:7.5.0'
Using slipt Play Services prevent the 65k error and make your app smaller
回答12:
This two google play service add into the build.gradle Its worked for me.. compile 'com.google.android.gms:play-services-appindexing:8.1.0' compile 'com.google.android.gms:play-services:8.1.0'
