I can not seem to get the android_id

Question

Here is the code i am using

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

Do I need to add permission to my manifest to have access to this variable?

Answer 1

i set android_id in onCreate now it works

private String android_id;


protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    Intent intent = getIntent();
    android_id = Secure.getString(getContentResolver(), Secure.ANDROID_ID);
