默认的Android的Browser中无法设置User Agent，但是在Browser的源码中可以看到，android提供了4中User Agent 具体代码如下：

在Browser的 src/com/android/browser/BrowserSettings.java
private static final String DESKTOP_USERAGENT = "Mozilla/5.0 (Macintosh; " +
           "U; Intel Mac OS X 10_6_3; en-us) AppleWebKit/533.16 (KHTML, " +
           "like Gecko) Version/5.0 Safari/533.16";

   private static final String IPHONE_USERAGENT = "Mozilla/5.0 (iPhone; U; " +
           "CPU iPhone OS 4_0 like Mac OS X; en-us) AppleWebKit/532.9 " +
           "(KHTML, like Gecko) Version/4.0.5 Mobile/8A293 Safari/6531.22.7";

   private static final String IPAD_USERAGENT = "Mozilla/5.0 (iPad; U; " +
           "CPU OS 3_2 like Mac OS X; en-us) AppleWebKit/531.21.10 " +
           "(KHTML, like Gecko) Version/4.0.4 Mobile/7B367 Safari/531.21.10";

   private static final String FROYO_USERAGENT = "Mozilla/5.0 (Linux; U; " +
           "Android 2.2; en-us; Nexus One Build/FRF91) AppleWebKit/533.1 " +
           "(KHTML, like Gecko) Version/4.0 Mobile Safari/533.1";

提供了4中不同的User Agent，但是在浏览器中无法进行设置。

在Browser的setting中添加设置User Agent的选项：
1.在 res/xml/browser_preferences.xml中添加：
<ListPreference
                android:key="user_agent"
                android:title="@string/pref_user_agent"
                android:defaultValue="0"
                android:entries="@array/pref_development_ua_choices"
                android:entryValues="@array/pref_development_ua_values"
                android:dialogTitle="@string/pref_user_agent_dialogtitle" />

2.在res/value/string.xml中添加对应的字符串，多语言的具体到不同的文件夹(自己添加)
<string name="pref_user_agent">User agent</string>

<string name="pref_user_agent_dialogtitle"  translatable="false">User Agent</string>
<string-array name="pref_development_ua_choices" translatable="false">
        <item>Android</item>
        <item>Desktop</item>
        <item>iPhone</item>
        <item>iPad</item>
        <item>Froyo-N1</item>
        <item>NexusOne</item>
        <item>Samsung i9000</item>
    </string-array>
    
    <string-array name="pref_development_ua_values" translatable="false">
        <item>0</item>
        <item>1</item>
        <item>2</item>
        <item>3</item>
        <item>4</item>
        <item>5</item>
        <item>6</item>
    </string-array>

3. 在 src/com/android/BrowserSettings.java 中添加
view plainprint?
public final static String PREF_USER_AGENT = "user_agent";

4.在 src/com/android/BroserPreferencesPage.java 中添加
private CharSequence getVisualUserAgent(String enumName) {
        CharSequence result = "";
        CharSequence[] visualNames = getResources().getTextArray(
                R.array.pref_development_ua_choices);
        CharSequence[] enumNames = getResources().getTextArray(R.array.pref_development_ua_values);

        if (visualNames.length == enumNames.length) {
            for (int i = 0; i < enumNames.length; i++) {
                if (enumNames[i].equals(enumName)) {
                    result = visualNames[i];
                }
            }
        }
        return result;
    }

5. 在BroserPreferencesPage.java的OnCreate方法中添加
e = findPreference(BrowserSettings.PREF_USER_AGENT);
    e.setOnPreferenceChangeListener(this);
    e.setSummary(getVisualUserAgent(
        getPreferenceScreen().getSharedPreferences()
        .getString(BrowserSettings.PREF_USER_AGENT, null)));

6.在BroserPreferencesPage.java的onPreferenceChange 方法中添加

else if (pref.getKey().equals(BrowserSettings.PREF_USER_AGENT)){
        pref.setSummary(getVisualUserAgent((String)objValue));
        return true;
    }

      7.在BrowserSettings.java的syncSharedPreferences方法中添加
userAgent = Integer.parseInt(p.getString(PREF_USER_AGENT, "0"));
