android – Snapchat如何检测XPosed框架？

为了确保SnapChat没有专门检查XPosed框架,我反编译Snapchat并运行grep -lri xposed.@L_450_4@没有结果.

检查是否安装了XPosed：

我敢肯定有很多方法可以检查是否安装了Xposed.我编写了以下方法获取当前安装的Xposed版本,如果在设备上找不到XposedBridge.jar,则返回null：

/**
 * Get the current Xposed version installed on the device.
 * 
 * @param context The application context
 * @return The Xposed version or {@code null} if Xposed isn't installed.
 */
public static Integer getXposedVersion(Context context) {
  try {
    File xposedBridge = new File("/system/framework/XposedBridge.jar");
    if (xposedBridge.exists()) {
      File optimizedDir = context.getDir("dex",Context.MODE_PRIVATE);
      DexClassLoader dexClassLoader = new DexClassLoader(xposedBridge.getPath(),optimizedDir.getPath(),null,ClassLoader.getSystemClassLoader());
      Class<?> XposedBridge = dexClassLoader.loadClass("de.robv.android.xposed.XposedBridge");
      Method getXposedVersion = XposedBridge.getDeclaredMethod("getXposedVersion");
      if (!getXposedVersion.isAccessible()) getXposedVersion.setAccessible(true);
      return (Integer) getXposedVersion.invoke(null);
    }
  } catch (Exception ignored) {
  }
  return null;
}

据我所知,Xposed总是在/ system / framework中有XposedBridge.jar,所以这应该适用于Xposed的官方版本,但在将来的版本中可能会中断.
