    1. 在文件末尾增加如下代码

      1. /// START. Network Firewall For Some Apps. By ShawnXiaFei@20180913.
      2. /// Need to set the list on every boot.
      3. /// @see FAQ10820 & FAQ20276
      4. private final static String[] blacklistPkgs = {
      5.  "com.baidu.input",      //Baidu Input
      6. };
      7. private void setFirewallUidChainRules(PackageManager pm){
      8.  final android.os.INetworkManagementService netManager = android.os.INetworkManagementService.Stub
      9.      .asInterface(ServiceManager.getService(Context.NETWORKMANAGEMENT_SERVICE));
      11.  try {
      12.      for(String pkg : blacklistPkgs){
      13.          int uid = pm.getPackageUid(pkg, UserHandle.myUserId());
      14.          //Log.e("Shawn", "SS >> setFirewallUidChainRules, uid = "+uid);
      15.          if(uid > 0){
      16.              netManager.setFirewallUidChainRule(uid, 1, true); //WIFI
      17.              netManager.setFirewallUidChainRule(uid, 0, true); //MOBILE
      18.          }
      19.      }
      20.  }
      21.  catch (/* PackageManager.NameNotFound */Exception e){
      22.      //Log.e("Shawn", "SS >> setFirewallUidChainRules, e = "+e);
      23.  }
      24. }
      25. /// END. Network Firewall For Some Apps. By ShawnXiaFei@20180913.

    2. 在如下方法末尾插入代码：

      1. /**
      2. * Starts a miscellaneous grab bag of stuff that has yet to be refactored
      3. * and organized.
      4. */
      5. private void startOtherServices() {
      7.  // 省略大量代码
      9.  /// M: RecoveryManagerService @{
      10.  try {
      11.      if (mRecoveryManagerService != null) {
      12.          mRecoveryManagerService.stopBootMonitor();
      13.      }
      14.  } catch (Throwable e) {
      15.      reportWtf("Failure Stop Boot Monitor", e);
      16.  }
      17.  /// @}
      19.  /// START. Network Firewall For Some Apps. By ShawnXiaFei@20180913.
      20.  setFirewallUidChainRules(mPackageManager);
      21.  /// START. Network Firewall For Some Apps. By ShawnXiaFei@20180913.
      22. }
