開源專案之Android imifirewall(防火牆)
阿新 • • 發佈：2019-02-09
imifirewall（艾米防火牆）是一款Android下的防火牆軟體，它主要用來幫助手機使用者解決日常使用中遇到的問題:電話騷擾，釣魚簡訊，手機垃圾，系統變慢等眾多問題，艾米防火牆暫時只支援簡訊過濾，來電攔截，程式聯網行為攔截和流量檢視等功能，以後會陸續新增更多實用的功能。
不錯的國產防火牆專案，專案如圖：
效果如圖：
主要原始碼分析：
public class Function { // jni載入以及本地呼叫 public static FileDescriptor createSubprocess(String cmd, String arg0, String arg1) { return createSubprocess(cmd, arg0, arg1, null); } public static native FileDescriptor createSubprocess(String cmd, String arg0, String arg1, int[] processId); // 建立子程序 public static native void setPtyWindowSize(FileDescriptor fd, int row, int col, int xpixel, int ypixel); // 設定視窗大小 public static native int waitFor(int processId); // 等待某程序 public static native String version(); // 版本資訊 static { System.loadLibrary("imiFunction"); } }
Jni專案就兩個檔案，如圖：
