如何在android中将publickey.xml文件的路径添加到InputStream？将文件publickey.xml放在哪里？

//如何在此处放置publickeyfile.xml的路径

InputStream in =

//获取inputstream的ObjectPNutStream

  ObjectInputStream oin =
new ObjectInputStream(new BufferedInputStream(in));
  try {
BigInteger m = (BigInteger) oin.readObject();
BigInteger e = (BigInteger) oin.readObject();
RSAPublicKeySpec keySpec = new RSAPublicKeySpec(m, e);
KeyFactory fact = KeyFactory.getInstance("RSA");
PublicKey pubKey = fact.generatePublic(keySpec);

  } catch (Exception e) {
throw new RuntimeException("Spurious serialisation error", e);
  } finally {
oin.close();
  }

在项目中创建一个res>raw文件夹

将publickeyfile.xml文件放入新文件夹

“Inputstream is=myResources.openRawResource（R.raw.publickeyfile）”

……应该行得通
