Android Studio , Google MapFragment - mapv2

问题

i know there are many question about this but it's about 2 days i work on this and i was unable to find a correct solution (i'm new to android). I need to create an app that can handle a map and draw some markers. I can't even show a map on my device :( Nexus4

This is what i have done :

i copy the google-play-services.jar into my libs dir and change the gradle.build to handle the new library :

dependencies {
compile files('libs/android-support-v4.jar' , 'libs/gcm.jar', 'libs/google-play-services.jar')
}

i already signed my app and enabled the mapv2 api and change the android manifest like this :

<uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="16" />

...

<uses-feature
        android:glEsVersion="0x00020000"
        android:required="true"/>

<permission
        android:name="com.metu.xxx.permission.MAPS_RECEIVE"
        android:protectionLevel="signature"/>

<uses-permission android:name="com.metu.xxx.permission.MAPS_RECEIVE"/>

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >

    <meta-data
            android:name="com.google.android.maps.v2.API_KEY"
            android:value="SIGNATURE_HERE -> ^_^"/>
...

my java class looks like this :

import android.os.Bundle;
import android.support.v4.app.FragmentActivity;

public class AtmActivity extends FragmentActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_atm);
    }
}

my xml layout looks like this :

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
          android:layout_width="match_parent"
          android:layout_height="match_parent"
          android:orientation="vertical" >

<fragment
        android:name="com.google.android.gms.maps.SupportMapFragment"
        xmlns:map="http://schemas.android.com/apk/res-auto"
        android:id="@+id/map"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />
</LinearLayout>

compiling this code is ok but when i tap on the button to show the activity the app crash :( This is the error log :

Somebody can help me ? or maybe can link a good how to to solve this ?

Thanks and sorry for my poor english :)

UPDATE :

it seems i completly wrong with this.

following this tutorial and everything went fine : http://android.rzeszow.net/?p=79

(there is a part missing in the copy files, you need to copy the jar and the settings to the libs file of the module)

回答1:

You need to reference google play services project and not only the jar.
