How to get android id in java without using of the class Activity?

Question

I can't using the following method because my class doesn't extends the Activity class: Is there a unique Android device ID?

Answer 1

Try like this

import android.content.Context;
import android.provider.Settings.Secure;

public class sample {


    public String getId(Context c)
    {

         String android_id = Secure.getString(c.getContentResolver(),
                                                                    Secure.ANDROID_ID); 

         return android_id;
    }
}

pass the context from your activity

sample s=new sample();

    String udid=s.getId(getApplicationContext());
    Toast.makeText(getApplicationContext(), udid, Toast.LENGTH_LONG).show();
