I want to get all connected players to game. I can get players that are in google+ circles but I want the player to get all users. I can't find what permission do I need to do this.
I am using this code to get players, but it always returns 0.
PendingResult<LoadPlayersResult> players = Games.Players.loadConnectedPlayers(mGoogleApiClient, false);
players.setResultCallback(new ResultCallback<Players.LoadPlayersResult>()
{
#Override
public void onResult(LoadPlayersResult result)
{
PlayerBuffer buf = result.getPlayers();
Toast.makeText(getApplicationContext(), "players"+buf.getCount(), Toast.LENGTH_SHORT).show();
}
});
this had been pre-announced and then announced a while ago already and method .loadConnectedPlayers() had been deprecated... which merely boils down to, that Google+ had been separated from Play Games and the functionality you are looking for is not available anymore.
in order to get a list of connected players, you would have to use your own API now. Just seen the question is old and had been posted before the announce - nevertheless this appears to be the current status.
I use Google Play Games Services and everythink working fine (leaderboards, random opponent etc etc)
But when a player call finishMatch(), the status of match.canRematch() is always "true", beyond the result.
If the player has won the battle may not be able to ask for a rematch!
I use this code to send the result:
Games.TurnBasedMultiplayer.finishMatch(mGoogleApiClient,
mMatch.getMatchId(), mMatch.getData(), myscore, creatorscore).setResultCallback(
new ResultCallback<TurnBasedMultiplayer.UpdateMatchResult>() {
#Override
public void onResult(
TurnBasedMultiplayer.UpdateMatchResult result) {
processResult(result);
}
});
I would like to disable the possibility of revenge. How can I do?
Ok. This IS an answer.
It is not possible from the API to disallow rematch.
However, I just discovered a workaround that achieves the same effect.
detect whether a match is a rematch by calling getMatchNumber() and getPreviousMatchData(). Cancel/Dismiss the match if the former isn't 1 or the latter isn't null. It ensures a rematch user input will have the same effect as a dismissal.
when a match is completed completely (cancelled, expired, or MATCH_STATUS_COMPLETE && MATCH_TURN_STATUS_COMPLETE), dismiss it right away. It minimizes the chance that the user will even see the "Match complete, rematch" UI. This check can also be checked periodically for matches in the inbox.
I have an Android game and I'd like to play a sound whenever a players unlocks an achievement,
but I can't seem to find a way to know when the user unlocks the achievement, since most of my achievements are incremental I have no way to code it on the client side, the only way would be some callback called when the Google API shows the achievement box, but I can't find any of those on the documentation... Only thing i found was this: Integrating Google Play services achievements and android notifications
#Override
public void onAchievementUnlocked(final String id)
{
//
}
but I have no idea how to implement that or how to call that method and I had no luck on Google
Use the following code:
Games.Achievements.incrementImmediate(GoogleApiClient apiClient, String id, int numSteps).setResultCallback(new ResultCallback<Achievements.UpdateAchievementResult>() {
#Override
public void onResult(UpdateAchievementResult result) {
if (result.getStatus().getStatusCode() == GamesStatusCodes.STATUS_ACHIEVEMENT_UNLOCKED) {
// play your sound. achievement was unlocked
}
}
});
This will increment your achievement by the amount of steps you want, and when it is done, it will return some of these codes. If the code is GamesStatusCodes.STATUS_ACHIEVEMENT_UNLOCKED, then it means that increment unlocked the achievement and you can play your sound.
I've built an Android app which is now on Play Market. From time to time, I make updates to it, and I'd like to let users know that a new version is available.
How can I send an update notification to the users of the app?
You do not need to do anything specific for this. Since you mentioned that you are using Google Play, the update notification is taken care of by Google Play.
You just need to update the APK with a higher versionCode and Google Play should do the rest.
Update 2020: now you can use in-app updates mechanism
Docs: https://developer.android.com/guide/playcore/in-app-updates
You can do this in a lot of ways, depending on when you want the user to be able to see that there is an update available.
If you want the user to know about the update when the app is started, just create a utility method (inside the onCreate method of your main/first Activity) that checks if a newer version is available in Google Play. If it does, display an alert dialog with a relevant message and an Intent which opens your app in Google Play when the user clicks on the positive button of the alert dialog.
If you are updating the app regularly, the user will keep getting this alert dialog every time the app is started and hence, may get irritated. Thus, this is not the best approach.
If you want the user to get a notification on the phone (and not when the user starts the app), you can use the AlarmManager class to schedule a background service which checks for an update at regular intervals. If the service finds that an upgrade is actually available, publish a notification with an intent that opens your app in Google Play.
Of course, another approach is to leave it to the OS itself. If the user has not set the "Automatically update" preference for your app, the user will get a notification regularly about an update available for your, as well as any other apps.
But not all users enable background data on their devices, so this is not completely reliable.
In the end, you must respect the users preferences. If the user does not want to automatically update the app, or does not want to see a nagging dialog box whenever he/she starts your app, don't alert the user about the update.
In my opinion, you should create a PreferenceActivity that has a preference like "Check for updates regularly", which can be set from within your app. If it is set, do the needful in your own service. May be even give the user an option to select the period after which the service will check for an update.
I hope this helps!
It is up to each phone owner if she wants to be notified on new versions by google play, and it's up to each phone's manufacturer if this is to be enabled by default.
If you however are in a situation where you "require" the user to update to the new version to be compatible with some form of protocol or you have a similar similar use case where you have a server component somewhere, you might want to notify the user of a potential version conflict in the UI based on information about what is the latest version.
This information can be grabbed directrly from google play, however as #Yahel pointed out in this question google play is a closed system with no official API, and you might need to rely on unpredictable undocumented API. There is an unofficial API library here.
This leaves only one option, which is to keep this information on your own server. If you allready have a serverside this might be trivial. Simply put the latest version in an XML file and retreive that at regular intervals from your code. If the version code is outdated, trigger the notification in your UI. Here is an example implementation for doing that.
I hope this was helpful :-)
I know this is an old question but still if people are coming here to check this question, Google is now providing official support for in-app notification for application update the full documentation can be found here
Use this : https://www.push-link.com/
Google Play will notify your users that the app has an update via the notification bar.
If you set up a notification system yourself, the likely result would be that, although the user is notified of an update sooner, when he/she goes to Google Play to install the update it will not yet be available. This is because there is a lag from the time you "publish" an app/update and the time until it appears on Play. Telling your users that there is an update when the update is unavailable would only lead to confusion and frustration.
My advice: stick with Google's update notification system and don't worry about trying to get users an update 15 minutes sooner.
Some people use Android Cloud-to-Device Messaging (C2DM) to notify their users of updates. I don't think I'd bother, since I think Google Play does a pretty good job of notifying me of updates already, and implementing C2DM adds a whole new dimension to writing an app (because it requires a server component). But maybe you want to offer your users a richer update notification than you get from Google Play.
#Davek804's answer above is wrong. android:versionCode is an integer value that represents the version of the application code, relative to other versions, so using "1.5b" there is incorrect. Use "15" (or "150") instead
Found a nice solution for your problem:
Let´s say you want to check for version updates manually on app start and notify your users for the new Update.
Step 1: Download android-market-api (not the .jar file, the full project!)
Step 2: After importing it to eclipse, write in your activity the following code:
MarketService ms = new MarketService(activity);
ms.level(MarketService.REVISION).checkVersion();
now, we need to modify MarketService.java, because it seems to be broken.
Step 3: rewrite callback method and add the following methods
protected void callback(String url, JSONObject jo, AjaxStatus status){
if(jo == null) return;
String googlePlayversion = jo.optString("version", "0");
String smartphone_version = "";
PackageInfo pInfo;
try {
pInfo = act.getPackageManager().getPackageInfo(act.getPackageName(), 0);
smartphone_version = pInfo.versionName;
} catch (NameNotFoundException e) {}
boolean new_version_avaible = compare(smartphone_version, googlePlayversion);
if(new_version_avaible){
showUpdateDialog(jo);
}
}
private static boolean compare(String v1, String v2) {
String s1 = normalisedVersion(v1);
String s2 = normalisedVersion(v2);
int cmp = s1.compareTo(s2);
String cmpStr = cmp < 0 ? "<" : cmp > 0 ? ">" : "==";
System.out.printf("result: "+"'%s' %s '%s'%n", v1, cmpStr, v2);
if(cmpStr.contains("<")){
return true;
}
if(cmpStr.contains(">")||cmpStr.contains("==")){
return false;
}
return false;
}
public static String normalisedVersion(String version) {
return normalisedVersion(version, ".", 4);
}
public static String normalisedVersion(String version, String sep, int maxWidth) {
String[] split = Pattern.compile(sep, Pattern.LITERAL).split(version);
StringBuilder sb = new StringBuilder();
for (String s : split) {
sb.append(String.format("%" + maxWidth + 's', s));
}
return sb.toString();
}
If you want to test it, modify googlePlayversion string to a higher version than your local one.
The source comparison method I used is from How do you compare two version Strings in Java?
There is also a very good approach for checking version and give user in app notification or when you want to forcefully update the application if you can decide the first connection of your app with the server.In the response of the first request you can send the current version of app stored on your server and then on client end you can take the appropriate action.
Advantages of this approach-:
1-No extra request for version no.
2-It is also applicable if you are downloading the app other than the google playstore.
3-you can also use this idea if you want to check the version at particular operation of your app ex- transaction(if you add a new payment gateway.)
Don't know if you want to walk extra miles. You can try out google appengine, which serve version number for your app and let you android app check the appengine to see if there is a new version when the application is launched. That way, it does not matter if your app is in google play market nor amazon app store nor if it is installed on the phone without those two via sideloading. It is not very hard to setup appengine just for serving your application version in json. Replace "Hello World" string with your app version name ...
This can be using a simple webservice just this is one of the way to acheive.
i.e., when ever the app launch hit that webservice with the current version of the user app and on the server you need to check whether any new version is available or not(Must maintain the newest version of the app) and send the corresponding response to the user. If any newer version is available prompt the user to download the newest version of the application and if no newest version is available then allow the user to continue.
Hope so atleast something must be useful to you.
There are two models that are basically used to tackle the issue.
Pull Based
Push Based
Its depends on the architecture or design of particular system that determines whether pull based or push mechanism is used.
For pull based model you just make one http request to concerned server regarding the new version of application. The current application version no can be saved in SQLLite in android application. This can be given to server and new version can be checked against it at the server.
For push mechanism you can use C2DM push notification service.. details of which are given at http://code.google.com/android/c2dm/
Generally when you upload a new application to Google play most users get a notification about an update, some will have the app automatically downloaded to their device, depending on the settings they have.
If you seriously want to make a notification from your app to ask them to update (so that everyone gets the notification, whatever their Google play settings are, then you will have to make a web service which returns the number of the newest version. You can then compare that inside your app and post a notification. You could use Google App Engine ( https://developers.google.com/appengine/) because that works with eclipse and java, which you probably already have.
I would not recommend this approach as it creates a lot of work for you to provide something that most users have already got.

When you re-upload your app to Google Play, if these two attributes have been changed from the previous upload, Google Play will automatically send notifications to users who have installed your app. This is the AndroidManifest file.
there a lot of q&a about how users can rate my app within the app,
but i need just a direct link to review\rate my app to send the user by mail and not to my app page in the market because there he need to cilck review then login and then write the review and this is exhausting and not user friendly.
tnx
In order not to disturb the user with annoying forms you can add a menu item that let the user rate the application through your application site in google play. After the user click in this option, this should not been showed again (even if the user did not rate the app at the end). This solution is quite user friendly, in my opinion.
Add a menu item like this (in res\menu[menu].xml):
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
(other options...)
<item android:id="#+id/MenuRateApp" android:title="#string/menu_Rate_app"
android:icon="#drawable/ic_menu_star"></item>
</menu>
In your main activity add the following in order to hide the option once the user has already rated your app:
#Override
public boolean onPrepareOptionsMenu(Menu menu)
{
MenuItem register = menu.findItem(R.id.MenuRateApp);
if(fApp.isRated()) {
register.setVisible(false);
}
return true;
}
Change the fApp.isRated() for a method or variable that keep a boolean saying if the user already rated the app (write and read this value using the sharedPreferences mechanism).
The code to redirect the user to your app site in Google Play could be like the following:
private boolean MyStartActivity(Intent aIntent) {
try {
startActivity(aIntent);
return true;
} catch (ActivityNotFoundException e) {
return false;
}
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
(other options code...)
if (item.getItemId() == R.id.MenuRateApp) {
//Try Google play
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setData(Uri.parse("market://details?id="+getPackageName()));
if (MyStartActivity(intent) == false) {
//Market (Google play) app seems not installed, let's try to open a webbrowser
intent.setData(Uri.parse("https://play.google.com/store/apps/details?id="+getPackageName()));
if (MyStartActivity(intent) == false) {
//Well if this also fails, we have run out of options, inform the user.
Toast.makeText(this, this.getString(R.string.error_no_google_play), Toast.LENGTH_LONG).show();
}
}
//Do not disturb again (even if the user did not rated the app in the end)
fApp.setRated(true);
}
return super.onOptionsItemSelected(item);
}
Hope this solution feets your requirements.
Note: part of the code has been borrowed from this site:
http://martin.cubeactive.com/android-how-to-create-a-rank-this-app-button/
Example:
The premise from where you start, saying that rating an app is exhausting and not user friendly is not applicable because the user should only rate your app when he is willing to "donate" 30 seconds of his life to rate your app. There is a minimal responsibility involved when rating other people work.
The farthest I'd go, since there are also ethics involved, is providing a button in the About section of my app with a link to the Market app screen containing my app, using an Intent to the market (search StackOverflow). Other apps constantly ask a user to rate... I find it bothersome, but at least they are not pushing me right into the Edit and star Views of the Market.
The question you need to ask yourself: do you need to disrupt the user experience of your app by automatically stopping the activity and displaying this "oh-my-gosh-rate-my-app" view in the Market app?
You don't need to push the user into that situation... chances are you will end up with more low ratings than good ratings. I'd take one star just because of that. :-)
Personally, I wouldn't do it and leave the way it is. My 2 cents, of course.
Based on a similar question I posted, the desired answer I was looking for was
https://play.google.com/store/apps/details?id= + your.package.name
This should be what you're looking for if a link is what you have in mind. The first part is the default starter, and the second part will be your package name.
