android - Boolean not keeping most recent value of Sharedpreference result -

my boolean variable not keeping current value of sharedprefs. in functions returns true of success:

// method async. call public boolean downloadmatchesasync(string date) {      brawtaapiadapter.rungetmatches(date, new callback<jsonkeys>() {          @override         public void success(jsonkeys jsonkeys, response response) {              success = jsonkeys.issuccess();             message = jsonkeys.geterrormessage();              if (!message.isempty()) {                 toast.maketext(myapplication.getappcontext(), message, toast.length_short).show();             }              gson gson = new gson();             string jsonobject = gson.tojson(jsonkeys); //converts java object json string'              downloaded = preferences.savetopreferences(activity, applicationconstants.match_data, jsonobject);             log.d(applicationconstants.tag,"in networkoperation " + downloaded); //is true @ point         }          @override         public void failure(retrofiterror error) {         }     }); // call async api       return downloaded; } 

however when call function in method in same class returns false here:

 // method async. call public void authenticateuserasync(string email, string password) {      brawtaapiadapter.runuserauthentication(email, password, new callback<jsonkeys>() {         @override         public void success(jsonkeys jsonkeys, response response) {             success = jsonkeys.issuccess();             message = jsonkeys.getmessage();              if (success) {                  boolean b = downloadmatchesasync(date);                 log.d(applicationconstants.tag, "in authenticateuserasync " + b); //is false @ point                  if(b){                     intent = new intent(activity, matchselect.class);                      activity.startactivity(i);                     activity.finish();                 }             }         }          @override         public void failure(retrofiterror error) {              toast.maketext(myapplication.getappcontext(), "incorrect credentials", toast.length_short).show();         }     }); // call async api  } 

this definition of downloaded variable:

  public class networkoperations {  private brawtaapiadapter brawtaapiadapter; // rest adapter private boolean success; private string message; private activity activity; private string data; private string date; private boolean downloaded = false; 

and definition of preference class:

 public class preferences {  private static final string prefname = "net.brawtasports.brawtasportsgps";  public static boolean savetopreferences(context context, string key, string value) {      sharedpreferences sharedpreferences = context.getsharedpreferences(prefname, context.mode_private);     sharedpreferences.editor editor = sharedpreferences.edit();     editor.putstring(key, value);     return editor.commit(); }  public static string readfrompreferences(context context, string key, string defaultvalue) {      sharedpreferences sharedpreferences = context.getsharedpreferences(prefname, context.mode_private);     return sharedpreferences.getstring(key, defaultvalue);  }  } 

i figure problem regarding scope of downloaded. how can solve this?

i think point here is:
in downloadmatchesasync, variable downloaded changed in async method.
in authenticateuserasync, use downloadmatchesasync normal sync method (the value 'downloaded' returned before work in downloadmatchesasync.success completed, see log 'in authenticateuserasync ' appear before 'in networkoperation ')
think changed below may solve problem:

    private boolean downloaded = false; private hashmap<string, boolean> authenticateusers = new hashmap<string, boolean>(); public boolean downloadmatchesasync(string date, final string email) {  brawtaapiadapter.rungetmatches(date, new callback<jsonkeys>() {      @override     public void success(jsonkeys jsonkeys, response response) {          success = jsonkeys.issuccess();         message = jsonkeys.geterrormessage();          if (!message.isempty()) {             toast.maketext(myapplication.getappcontext(), message, toast.length_short).show();         }          gson gson = new gson();         string jsonobject = gson.tojson(jsonkeys); //converts java object json string'          downloaded = preferences.savetopreferences(activity, applicationconstants.match_data, jsonobject);         log.d(applicationconstants.tag,"in networkoperation " + downloaded); //is true @ point         // if downloaded , user authenticated, start activity         if (downloaded) {             boolean isauthenticated = authenticateusers.get(email);             if (isauthenticated != null && isauthenticated) {                 intent = new intent(activity, matchselect.class);                  activity.startactivity(i);                 activity.finish();             }         }     }      @override     public void failure(retrofiterror error) {     } }); // call async api    return downloaded; }  public void authenticateuserasync(final string email, string password) {  brawtaapiadapter.runuserauthentication(email, password, new callback<jsonkeys>() {     @override     public void success(jsonkeys jsonkeys, response response) {         success = jsonkeys.issuccess();         message = jsonkeys.getmessage();         // store authenticate result         authenticateusers.put(email, success);         if (success) {              // boolean b = downloadmatchesasync(date);             // check if work in downloadmatchesasync completed;             boolean b = downloaded;             log.d(applicationconstants.tag, "in authenticateuserasync " + b); //is false @ point              if(b){                 intent = new intent(activity, matchselect.class);                  activity.startactivity(i);                 activity.finish();             } else {                 downloadmatchesasync(date, email);             }         }     }      @override     public void failure(retrofiterror error) {          // store authenticate result         authenticateusers.put(email, false);         toast.maketext(myapplication.getappcontext(), "incorrect credentials", toast.length_short).show();     }  }); // call async api 

}

hope help
