Context is the instance of the current class in which you will call this method. — Deepak Rana, Sep 02 '17 at 02:52
@DeepakRana No it isn't. Its the Activity, Service, or Application which is running. Not the class. If that's all it was, you'd use this. — Gabe Sechan, Sep 02 '17 at 03:12

Create context for you application like this

private Context context = this;

Put this lines inside onCreate

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

    Toast.makeText(context, "android_id= " + android_id, Toast.LENGTH_LONG).show();
