Here is the second Activity where i am reading the value from shared preference i am getting null for first time second time its reading the value
public class Main2Activity extends AppCompatActivity {
String idddd;
TextView text;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main2);
text=(TextView)findViewById(R.id.text);
SharedPreferences sharedPreferences =
PreferenceManager.getDefaultSharedPreferences(this);
`idddd = sharedPreferences.getString`("CUSTOMER_ID","");
text.setText(idddd);
}
}
