What do you mean by ‘previous android_id’? Previous to what?

Before I do Factory data reset. Because android_id change in every reset.

I'm not exactly sure what you're asking either, in reference to android_id. So this is admittedly a shot in the dark.

It sounds like you created a password protected zip file? If so, whatever password you gave it when you created it would remain the same from there on out. Resetting the phone wouldn't change the file's password. You could even transfer it to a computer and still open it with the password. So have you tried using your original password to open it?

It would be helpful if you can clarify exactly what you mean by "android_id." Are you saying you used some identification listing from within your phone as the password, such as the IMEI number? All of the info like that I'm familiar with wouldn't change after a factory reset.

I don't know the password of my file because i write an application , in this application it set password of file to android_id programmatically.
You are right the password is fixed. I reset my phone and android_id is changed and I don't know how to access to previous android_id

If you're writing applications, you're way ahead of most Android Central members. I had to research 'android_id' since I'd never even heard of it. It's described here:

...with thanks to Android Developers.

I'm sure there are Android Central members here who will understand your problem. If you wish, I can move the thread to our Developers Lounge forum.

Unfortunately, there's no way to "recover" a previous ID. If the program you developed was supposed to unzip by getting the ID from the phone, that's just bad program development - you never use a password you can't get to. At the very least, you have a debug mode that writes the password out to a text file. Then you turn off debug mode.

Since you wrote the application, you have the source code, so just recompile it and rezip it, but think about that password method first.
