the manifest:

<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android"     package="com.cefetmgrdctcc.sgtp"     android:versioncode="1"     android:versionname="1.0" >      <uses-sdk         android:minsdkversion="8"         android:targetsdkversion="18" />      <permission         android:name="com.cefetmgrdctcc.sgtp.permission.maps_receive"         android:protectionlevel="signature"/>      <uses-permission android:name="com.cefetmgrdctcc.sgtp.permission.maps_receive"/>     <uses-permission android:name="android.permission.access_network_state" />     <uses-permission android:name="android.permission.internet"/>     <uses-permission android:name="android.permission.write_external_storage"/>     <uses-permission android:name="com.google.android.providers.gsf.permission.read_gservices"/>     <uses-permission android:name="android.permission.access_coarse_location"/>     <uses-permission android:name="android.permission.access_fine_location"/>      <uses-feature         android:glesversion="0x00020000"         android:required="true"/>          <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="hidden key"/>         <activity             android:name="com.cefetmgrdctcc.sgtp.mainactivity"             android:label="@string/app_name" >             <intent-filter>                 <action android:name="android.intent.action.main" />                  <category android:name="android.intent.category.launcher" />             </intent-filter>         </activity>     </application>  </manifest>

the layout of map control:

<fragment     android:id="@+id/googlemap"     android:layout_width="match_parent"     android:layout_height="match_parent"     class="com.google.android.gms.maps.supportmapfragment" />

i've imported google play services project , marked on google api console services list "google maps api v2", "google maps api v3" , "google maps android api v2", seems map fragment still not being able authenticate.

map fragment blank grey square on middle of screen, ideas why happening?

hi having exact same problem. tried docs said nothing seemed work.

the thing worked me uninstalling , reinstalling application (not rebooting worked) because apparently if make 1 mistake on configuration system caches failed authentication , maps won't work after fixing configuration.

so try following docs , guides on configuring google maps api on android every time change on configuration uninstall , reinstall.

c# - Send Image in Json : 400 Bad request -

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!
