Problems in first android/java tutorial -


i getting started attempting learn eclipse java android programming. in fact, i'm working on first basic sample app in tutorial @ developer.android.com. have following activity_main.xml:

<linearlayout xmlns:android="http://schemas.android.com/apk/res/android"     xmlns:tools="http://schemas.android.com/tools"     android:layout_width="match_parent"     android:layout_height="match_parent"     android:paddingbottom="@dimen/activity_vertical_margin"     android:paddingleft="@dimen/activity_horizontal_margin"     android:paddingright="@dimen/activity_horizontal_margin"     android:paddingtop="@dimen/activity_vertical_margin"     tools:context=".mainactivity" >     android:orientation="horizontal" >      <edittext android:id="@+id/edit_message"        android:layout_weight="1"         android:layout_width="0dp"         android:layout_height="wrap_content"         android:hint="@string/edit_message" />      <button         android:layout_width="wrap_content"         android:layout_height="wrap_content"          android:text="@string/button_send"     android:onclick="sendmessage" />      </linearlayout>

and following strings.xml

<?xml version="1.0" encoding="utf-8"? > <resources>      <string name="app_name">my first app2</string>     <string name="edit_message">enter message</string>     <string name="button_send">send</string>     <string name="action_settings">settings</string>     <string name="title_activity_main">mainactivity</string>     <string name="title_activity_display_message">my message</string>     <string name="hello_world">hello world!</string>  </resources>

as can see have button_send string , edit_message string in strings.xml both referenced in activity_main.xml. however, build yields error "no resource found matches given name (at 'text' value '@string/button_send')". ideas, please?

here couple ideas:

  1. make sure strings.xml in res/values folder.
  2. clean project (project->clean). delete gen folder , re-generate it. time make change resources, it's idea clean project , regenerate of r.id.* values.

edit:

you can go eclipse gui xml file , right-click button. click "edit text", should bring string values. should able see button_send. if don't, there's issue strings.xml.

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!
