由于宿舍網(wǎng)絡(luò)情況比較復(fù)雜，想為tattoo搭建一個proxy，沒想到在android中沒有找到設(shè)置proxy的地方。上網(wǎng)查了一篇文章，可以解決這個問題。

轉(zhuǎn)自 http://alexmogurenko.com/blog/programming/android-how-to-set-proxy-for-android-browser/

下面是原文

There are many reasons to make browser serf pages through proxy server:

• someone wanna catch http requests/responses
• someone wanna hide his IP
• so on

What to do if you want set proxy for android browser? there some ways:

• add record to database: /data/data/com.android.providers.settings/databases/settings.db

1. pull database to pc add record (using for example sdk tool sqlite3) and replace existing db
2. make changes in database directly on device

but as for me there exist simplier way, do it by your Java application using Settings provider:

Settings.System.putString(getContentResolver(), Settings.System.HTTP_PROXY, "proxy_ip:proxy_port");

where proxy_ip/proxy_port = IP/port of proxy that you going to use.

there left one problem, it will not work if we will not add one string to manifest file, here it is:

<uses-permission android:name=”android.permission.WRITE_SETTINGS” />

Thats all, now it works, here is code:

package com.BrowserSettings;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.provider.Settings;

public class BrowserSettingsUI extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);

final Button button = (Button) findViewById(R.id.Button01);
button.setOnClickListener(new Button.OnClickListener() {
public void onClick(View v) {
try
{
Settings.System.putString(getContentResolver(), Settings.System.HTTP_PROXY, "127.0.0.1:100");//enable proxy
}catch (Exception ex){
}
}
});

final Button button2 = (Button) findViewById(R.id.Button02);
button2.setOnClickListener(new Button.OnClickListener() {
public void onClick(View v) {

try
{
Settings.System.putString(getContentResolver(), Settings.System.HTTP_PROXY, "");//disable proxy
}catch (Exception ex){
}
}
});

}
}

manifest file:

<?xml version=”1.0″ encoding=”utf-8″?>
<manifest xmlns:android=”http://schemas.android.com/apk/res/android”
package=”com.BrowserSettings”
android:versionCode=”1″
android:versionName=”1.0.0″>
<application android:icon=”@drawable/icon” android:label=”@string/app_name”>
<activity android:name=”.BrowserSettingsUI”
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.WRITE_SETTINGS” />
</manifest>
