I am developing an application that when it opens it get inbox and facebook notifications. I am able to get inbox and notification messages from Facebook in my android application every minute using Alarm Manager. But this consumes a lot of battery of the smartphone. Is there a way to get notifications and inbox in real time so It doesn't have to be requesting every minute?
This is my code:
MainFragment class
public class MainFragment extends Fragment {
private static final String TAG = "MainFragment";
private Activity context;
private Session.StatusCallback callback = new Session.StatusCallback() {
@Override
public void call(Session session, SessionState state, Exception exception) {
onSessionStateChange(session, state, exception);
}
};
private UiLifecycleHelper uiHelper;
private TextView InboxMessage,NotificationMessage,text1,text2;
private LoginButton authButton;
PendingIntent pi;
BroadcastReceiver br;
AlarmManager am;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.activity_login, container, false);
authButton = (LoginButton) view.findViewById(R.id.authButton);
authButton.setFragment(this);
authButton.setPublishPermissions(Arrays.asList("manage_notifications"));
InboxMessage= (TextView) view.findViewById(R.id.InboxTextView);
NotificationMessage= (TextView) view.findViewById(R.id.NotificationsMessageTextView);
text1= (TextView) view.findViewById(R.id.textView1);
text2= (TextView) view.findViewById(R.id.textView2);
context=this.getActivity();
onClickNotifications();
return view;
}
private void onSessionStateChange(final Session session, final SessionState state, final Exception exception) {
if (state.isOpened()) {
final Calendar TIME = Calendar.getInstance();
am.setRepeating(AlarmManager.RTC,TIME.getTime().getTime(), 1000*60, pi);
} else {
Log.i(TAG, "Logged out...");
text1.setVisibility(View.INVISIBLE);
InboxMessage.setVisibility(View.INVISIBLE);
NotificationMessage.setVisibility(View.INVISIBLE);
text2.setVisibility(View.INVISIBLE);
}
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
uiHelper = new UiLifecycleHelper(getActivity(), callback);
uiHelper.onCreate(savedInstanceState);
}
@Override
public void onResume() {
super.onResume();
uiHelper.onResume();
Session session = Session.getActiveSession();
if (session != null &&
(session.isOpened() || session.isClosed()) ) {
onSessionStateChange(session, session.getState(), null);
}
uiHelper.onResume();
}
public void onClickNotifications(){
br = new BroadcastReceiver() {
@Override
public void onReceive(Context c, Intent i) {
final Session session =Session.getActiveSession();
if(session.isOpened()){
String aaa=new String();
aaa="SELECT title_text,updated_time FROM notification WHERE recipient_id=me() AND is_unread=1";
Bundle params = new Bundle();
params.putString("q", aaa);
new Request(session,"/fql",params,HttpMethod.GET,new Request.Callback() {
public void onCompleted(Response response) {
try
{
GraphObject go = response.getGraphObject();
JSONObject jso = go.getInnerJSONObject();
JSONArray arr = jso.getJSONArray( "data" );
String splitting=arr.toString().replaceAll("\\\\|\\{|\\}|\\[|\\]", "");
String[] arrayresponse=splitting.split("\\,");
String s = "";
for (int i = 0; i < arrayresponse.length; i++) {
if (arrayresponse[i].length()>13){
if (arrayresponse[i].substring(1,13).equals("updated_time"))
s+="* "+getDate(Long.valueOf(arrayresponse[i].substring(15,arrayresponse[i].length())))+"\n";
else
s+=" "+arrayresponse[i].substring(14,arrayresponse[i].length()-1)+"\n\n";
}
}
text2.setVisibility(View.VISIBLE);
NotificationMessage.setVisibility(View.VISIBLE);
NotificationMessage.setMovementMethod(new ScrollingMovementMethod());
NotificationMessage.setText(s);
readMailBox(session);
}catch ( Throwable t )
{
t.printStackTrace();
}
}
}
).executeAsync();
}
else{
NotificationMessage.setVisibility(View.INVISIBLE);
Log.i(TAG, "Logged out...");
}
}
};
this.getActivity().registerReceiver(br, new IntentFilter("com.authorwjf.wakeywakey") );
pi = PendingIntent.getBroadcast( this.getActivity(), 0, new Intent("com.authorwjf.wakeywakey"), 0 );
am = (AlarmManager)(this.getActivity().getSystemService( Context.ALARM_SERVICE ));
}
private String getDate(long time) {
Calendar cal = Calendar.getInstance(Locale.ENGLISH);
time=time*1000;
cal.setTimeInMillis(time);
return DateFormat.format("dd-MM-yyyy hh:mm:ss aa", cal).toString();
}
public void readMailBox(Session session){
String aaa=new String();
aaa="SELECT timestamp,sender,body FROM unified_message where thread_id in (select thread_id from unified_thread where folder = 'inbox') and unread=1";
Bundle params = new Bundle();
params.putString("q", aaa);
new Request(session,"/fql",params,HttpMethod.GET,new Request.Callback() {
public void onCompleted(Response response) {
try
{
GraphObject go = response.getGraphObject();
JSONObject jso = go.getInnerJSONObject();
JSONArray arr = jso.getJSONArray( "data" );
String splitting=arr.toString().replaceAll("\\\\|\\{|\\}|\\[|\\]", "");
String[] arrayresponse=splitting.split("\\,");
String s = "";
for (int i = 0; i < arrayresponse.length; i++) {
if (arrayresponse[i].length()>10){
if (arrayresponse[i].substring(1,10).equals("timestamp"))
s+=getDate(Long.valueOf(arrayresponse[i].substring(13,arrayresponse[i].length()-4)))+"\n";
else if (arrayresponse[i].substring(1,5).equals("name"))
s+="* "+arrayresponse[i].substring(8,arrayresponse[i].length()-1)+"\n";
else if (arrayresponse[i].substring(1,5).equals("body"))
s+=arrayresponse[i].substring(7,arrayresponse[i].length())+"\n\n";
}
}
text1.setVisibility(View.VISIBLE);
InboxMessage.setVisibility(View.VISIBLE);
InboxMessage.setMovementMethod(new ScrollingMovementMethod());
InboxMessage.setText(s);
}catch ( Throwable t )
{
t.printStackTrace();
}
}
}
).executeAsync();
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
uiHelper.onActivityResult(requestCode, resultCode, data);
super.onActivityResult(requestCode, resultCode, data);
Session session =Session.getActiveSession();
List<String> permissions = session.getPermissions();
if (!permissions.contains("read_mailbox")) {
Session.NewPermissionsRequest newPermissionsRequest = new Session.NewPermissionsRequest(context, Arrays.asList("read_mailbox"));
session.requestNewReadPermissions(newPermissionsRequest);
readMailBox(session);
} else {
readMailBox(session);
}
}
@Override
public void onPause() {
super.onPause();
uiHelper.onPause();
}
@Override
public void onDestroy() {
uiHelper.onDestroy();
am.cancel(pi);
this.getActivity().unregisterReceiver(br);
super.onDestroy();
}
@Override
public void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
uiHelper.onSaveInstanceState(outState);
}
}
In another words my question is: Is there a way to keep listening to inbox and notifications and automatically get new messages instead of requesting every minute?
