AdFree Detector 通过改变广告网络的IP地址、本地IP(改变hosts文件),使大部分的广告被屏蔽。

关键类Detector，如下：

public class Detector {/* * com.bigtincan.android.adfree/.FreeMe */private static final String ADFREE_PACKAGE_NAME = "com.bigtincan.android.adfree";private static final String ADFREE_MAIN_ACTIVITY = "com.bigtincan.android.adfree.FreeMe";public static boolean isAdFreeInstalled(Context context) { //是否初始化PackageManager pm = context.getPackageManager();Intent mainIntent = new Intent(Intent.ACTION_MAIN, null);mainIntent.setClassName(ADFREE_PACKAGE_NAME, ADFREE_MAIN_ACTIVITY);mainIntent.addCategory(Intent.CATEGORY_LAUNCHER);List<ResolveInfo> apps = pm.queryIntentActivities(mainIntent, 0);if (apps.size() == 1) {return true;} else {return false;}}public static boolean isHostAltered(Context context, String hostname) { //是否主机已改变ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);if (cm.getActiveNetworkInfo().isConnected()) {try {/* * 127.0.0.1 analytics.admob.com 127.0.0.1 analytics.live.com * 127.0.0.1 analytics.msn.com 127.0.0.1 c.googleanalitics.net * 127.0.0.1 feedads.googleadservices.com 127.0.0.1 * googleads.g.doubleclick.net 127.0.0.1 * googleads2.g.doubleclick.net */InetAddress addr = null;if (hostname != null && hostname.length() > 0) {addr = InetAddress.getByName(hostname);} else {addr = InetAddress.getByName("googleads.g.doubleclick.net");}if (addr.getHostAddress().equals("127.0.0.1")) {return true;} else {return false;}} catch (Exception e) {e.printStackTrace();}return false;} else { // no network connection, we dont carereturn false;}}}

项目使用它，需要添加的权限：

<uses-permission android:name="android.permission.INTERNET"/><uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>

先检测它是否初始化了

boolean flag = Detector.isAdFreeInstalled(context);

确定特定主机是否改变

isAltered = Detector.isHostAltered(context, "analytics.admob.com");
