Google MapActivity not displaying map

问题

I am trying to get google maps working. It is not displaying the map. I get the following error in LogCat

Couldn't get connection factory client

I have been through all the duplicate posts, and made the following changes

Ensured that uses-permission and uses-library are inside tag
used debug.keystore instead of custom
signed up with google maps using my private key, and updated my MapView with the maps key in the xml (for this public post, I have changed it)
Exported my app, and used debug.keystore to build it

I am running it on emulator. Maps on emulator works.

Android Manifest

<application
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name" >
    <uses-library android:name="com.google.android.maps" />
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
    <uses-permission android:name="android.permission.INTERNET"/>
    <uses-permission android:name="android.permission.READ_PHONE_STATE"/>
    <activity
        android:name=".MyActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity android:name=".GetLocation" android:label="@string/app_name"/>
</application>

location.xml

<?xml version="1.0" encoding="utf-8"?>
<com.google.android.maps.MapView
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:clickable="true"
    android:apiKey="0psLgKtDQLB35-XJXUrjR4bKHIBDRuHu-O-xVhg"
    android:id="@+id/location"
/>

sudo keytool -list -alias androiddebugkey -storepass android -keypass android -keystore     debug.keystore

returns

androiddebugkey, 20 Mar, 2012, PrivateKeyEntry, 
Certificate fingerprint (MD5): 20:D3:54:D9:F8:70:17:A4:BA:21:5C:98:88:27:45:E0

Fixed I put uses-permission outside of Application tag And uses-library inside of Application tag

回答1:

uses-permission outside the <application> Tag. and

Couldn't get connection factory client

And its map-api key problem .And you should create Fresh Map-api key .

回答2:

I believe you might have got the solution for this question but for anyone else looking for the help for same question here's the ans

try to put

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>    
<uses-permission android:name="android.permission.INTERNET"/>

outside your application tag

just leave <uses-library android:name="com.google.android.maps" /> inside the tag

add metadata inside the application tag as

<meta-data android:name="com.google.android.maps.v2.API_KEY"
android:value="your API key"/>

and it will definitely work fine
