标签：return mBase 校验 content APK Override PackageManager public 打包
新手学习Android逆向 ，还没有开始就遇到了问题了，APP反编译使用了.so文件验证签名。
.so文件分析对于我这样的小白来说太难了。所以逆向之路开没有进入大门就结束了；
后来无意间看到吾爱破解的一篇文章 https://www.52pojie.cn/thread-1227128-1-3.html
这个思路对于我这样无法破解.so文件的新手来说是一个不错的方法；
写一个HookPackageManager，专门用来HOOK各种PM相关方法：
public class HookPackageManager extends PackageManager {
private PackageManager mBase;
public HookPackageManager(PackageManager base) {
this.mBase = base;
}
@Override // android.content.pm.PackageManager
public PackageInfo getPackageInfo(String packageName, int flags) throws PackageManager.NameNotFoundException {
//这里我没有进行架包名判断 感觉不需要
PackageInfo pkgInfo = new PackageInfo();
//获得签名字节是使用Java代码 下面会详细说明

}写一个HookMainActivity，就不在说了；
然后说明一下签名字符串的获得方法；
Android 读取APK签名信息_LIAN_1988的专栏-CSDN博客 查看了这个文章实现的
private static String toCharsString(byte[] sigBytes) {
byte[] sig = sigBytes;
System.out.println(Arrays.toString(sig));
在签名转字符中打印出需要的字节，这样可以直接复制到上面的签名字节中；
然后就是把Java文件转smali文件了；使用的是Android studio 的java2smali插件生成；
然后就是把文件加到项目中了，我测试的APP是可以通过使用的；
