good morning - hope has had enjoyable weekend.

i having issues following tutorial @ https://developer.chrome.com/multidevice/webview/gettingstarted

everything going until reach step regarding edit of mainactivity class. step 3 in section add webview: https://developer.chrome.com/multidevice/webview/gettingstarted#add_the_webview

here content of androidmanifest.xml:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"     package="com.example.nathan.myapplication" >      <application         android:allowbackup="true"         android:icon="@drawable/ic_launcher"         android:label="@string/app_name"         android:theme="@style/apptheme" >         <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>     </application>      <uses-permission android:name="android.permission.internet" />  </manifest> 

and here myactivity.java:

package com.example.nathan.myapplication;  import android.app.activity; import android.os.bundle; import android.view.menu; import android.view.menuitem; import android.webkit.webview;  public class myactivity extends activity { private webview mwebview; // added nd guthrie 8.15.2014:2229  @override  protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_my);     mwebview = (webview)findviewbyid(r.id.activity_my_webview);  // added nd guthrie 8.15.2014:2231 } @override public boolean oncreateoptionsmenu(menu menu) {     // inflate menu; adds items action bar if present.     getmenuinflater().inflate(r.menu.my, menu);     return true; }  @override public boolean onoptionsitemselected(menuitem item) {     // handle action bar item clicks here. action bar     // automatically handle clicks on home/up button, long     // specify parent activity in androidmanifest.xml.     int id = item.getitemid();     if (id == r.id.action_settings) {         return true;     }     return super.onoptionsitemselected(item); } } 

i have tried suggestions based on these links here on stackoverflow:

error r class import in android

android studio don't generate r.java import project

r.id cannot resolved

for error r class import, have attempted adding line

import com.testapp.hellowebview.r; 

but no success, testapp not recognized. stands reason, since have not named 'testapp' in app here, not understand how fix it.

i tried deleting generated folder , cleaning , rebuilding project. however, obtain same results.

i know silly little thing, have been searching google , stackoverflow days now, , seems there not seeing.

any ideas? please advise.

thank time!

best, nathan

the way works xml files compiled resources in background eclipse, , r.java gets generated allows project refer these resources. if put "r.id.blah" or "r.layout.blah" or whatever eclipse , isn't recognised, means 1 of following:

1. your xml files don't have corresponding elements. r.java being created, doesn't contain "r.id.blah" or whatever you're using, because xml files don't contain elements compile ids.
2. r.java couldn't compiled @ all. that'll case if there errors in project. you're best off making sure there no errors (no red crosses anywhere), , seeing whether r.java appears. once you've done that, you'll able find out ids being generated, , should point in direction of what's missing or inconsistent in xml files.
