startActivity and intercept intent extras

Question

I'm considering to do the following for log in a user:

Intent intent= new Intent(this,DoLoginActivity.class);
intent.putExtra("login",mLogin);
intent.putExtra("password",mPassword);
startActivity(intent);

Is that secure, or other apps can easily listen/read the intent parameters?

Answer 1

Your current approach is secure, no other app can listen or read these values.

You are using Explicit intent [you actually specify the activity that is required to respond to the intent] and that is listen by only that class which is declared in Intent. So this is Secure.

Answer 2

For your information you can pass object through intent, this will help in the scenario of passing bunch of values. Link

Answer 3

为了增强安全性，应该将密码存储在char数组（char []）中，然后在使用后通过清除数组来清除密码，如下所示：

Arrays.fill(password, (char) 0);
