[Q] How do apps know? - Android Q&A, Help & Troubleshooting

Hey guys my girlfriend plays a game on her android called "Tap Fish". In this came you can download other games and you get some prize for doing it. She asked me the other day "how does the app know that I downloaded and installed the game?". I thought that was a pretty interesting question. How do the apps that offer this service know if you have downloaded and installed the game?
Thanks guys!

It makes a connection with market to verify the download of another app. Also, it can be ptrogrammed to wacth system files to see if the app has runnend ever for a certainly amount of time. Is just download a new app to get rewarded or u may exec the new app?

She says it depends on the app. Most of the time its just download and open the app. But some require you to play till level like 2 or 3.
What system files is it tracking?

The Official Amzon AppStore deal of the day

As we all know Amazon has a App of the day going on. This is the official thread for us to post, talk about, and broadcast these applications. How ever it can get extremely sticky. They are only free for 24hrs and since it is Amazon's choice to eat the cost for these please do not post links to any .apks, including sites to where the .apks can be found. you may only post links to the Amazon site and/or the Google Market site. I did talk to the local mod before posting this and according to them posting links to the .apks or source of .apk will be treated as warez and punished accordingly.
Mod edit: Any links anywhere outside of the OP will be removed, and if they are links to the apks or other sites hosting the apks they will be treated as warez.
as of 4/28/11 i will not longer updating this daily.
im loving the Amazon app store, so far ive gotten 3 paid apps for free. first it was world series of poker 4.99, doodle jump .99, and shazam 4.99.

Anyone else have the app store working great, update the app and now it keeps asking for me to associate a credit card with my 1-click settings? Why do I need to keep my card on their servers for some hacker to compromise just to buy a free app?

The reason they do that is so if you want to buy an application it the price will be applied directly to the card on file.
glad someone started this...i think i suggested this after the third or fourth day due to the inflood of free app threads (didnt start it myself because i do not have the time to maintain it)
On another note...this is the first thing i do every morning..check the free app

I just wanted to start it so we could have a common place to talk about the Deal of the Day. I know they'll be a massive flood of people talking about stuff. I'm going to be whoring the apps. The games i'm letting slide under the radar.
You can select install on the app of the day, let it authenticate and download, then choose not to install and it's considered purchased. Just so everyone knows. That way you can get all of the apps they offer even if they don't sound appealing or useful atm. Never know, once the day is up you'll not have that chance again...
Is there any way to receive an automatic notification of what the free app is each day? I know one of these days I'm going to forget to check...

The only way possible would be for you to subscribe to this thread, and when i update it should notify you.
But keep in mind i'm only doing apps, not games.

you could set a daily alarm for a time that is convenient for you with a note saying "check amazon for free app"

Looks like they stopped giving out free apps.
Also if you delete the Amazon App Store from your phone you will not be able to open any of the Apps you downloaded through it.

Nevermind I was wrong. I looked last night at a time when they should have had another free app up and the space was completely blank. I searched online and found a thread on another site that said they were stopping the free app a day giveaway. However I just looked and they have a new one up.
what if you download the app of the day and save it to sd card and uninstall the amazon app store...will the app/game still play after cause its now on ur sdcard...
So is this not being updated or what?
BTW, Today's free app is PhotoVault.

Wooo Hooo sent from my little Acie.
I installed it, just looks nice, but I regret that I did. Before, I was able to download paid applications (by turning back to old market versions and then using a warez application which I cant mention here), but now I can't go back to old versions, and neither I cant uninstall google play. Sucks. But I can download free apps and updates of my paid apps.
Same here Transformed it self

I have been waiting to see what it automatically does. So far just license agreement. Everything else the same no offer of update even. Tbh I'm not interested in upgrading so long as Market still works.
no issue with the market 3.4.4 here, paid and free
i cant access to my google play store it always says authentication required.....

Difference in app size while downloading from Play Store

Hi there guys,
Today I was downloading this app for the very first time. It's showing app size of ~3MB but while downloading, it shows app size of ~1.6MB. I have never faced this problem with other apps.
Why is this happening?
Thanks
Was you updating the app?
I only ask because the playstore will now only update the files in the app that need updating rather than downloading the whole app again. It was bought in to save peoples data usage
Also the same with JB itself
Hope this helps
Thanks for your reply. I know about the new update feature that's why I wrote above that I was downloading this app for the very first time. And that's why it caught my attention. I downloaded it again and same thing happened.
If it's not compressed it must be something to do with a download within the app.. Or its furrgged upp
Mine does the same btw

[Q] play store bug

I've searched for days whether anyone else had experienced this problem regarding play store but couldn't find proper solution!
The problem is, whenever i download large apps from play store (say, 50+ MB), the download suddenly stops. the play store app says its downloading but not a single byte is being downloaded. And the other problem is, i cannot resume downloads. What can i do to fix it?
I thought this would have occurred coz of flashing excessive ROMs so i flashed back to stock but even this didn't solve this problem! this is very frustrating as i am trying to download an app ( of about 800+ MB) for days but couldn't finish downloading it! any suggestion would be appreciable! T

Menu-Settings-WiFi-Menu-Advanced. Make sure it's not set to time out after a while. Also make sure that you actually are connecting to the router, with permission. I know that my router here at home you connect to it, and see it. But you cannot actually use it till you enter the password.

Yea i do. The app downloads but stops downloading after certain time. It gets stuck ( let's say at 70%)
The "downloading" notification on the notification bar also gets stuck. I have to restart my phone to remove it.
P.S. Sorry for late reply.

If the available space in the folder /cache on your phone storage is smaller than 50MB, then you can't download apps larger than 50MB coz /cache is the place to save temporary app files you download from google play. But you can try Java-based Real APK Leecher on your PC to download large apks directly from the store.
Are you on the latest version of the Play Store?

I guess this is my problem. Coz my phone storage is low; which means /cache is of low storage too right??

That's the point. The most important defect of android is that the manufacturers paid too much attention on how to adapt the OS for various devices and ignored the actual user experience. As for your question, I searched around and get no answer.
Yet I can give you two suggestions:
1. Download apps from some third-party app download sites which allow you to get apks and bypass play store.
http://www.tipsotricks.com/2012/07/top-10-sites-to-download-free-android-apps.html
Pick up one in this link.
2. Repartition your phone storage. I'm not sure about how to do it coz I haven't tried that before. But I know there are many idle space in other partition like /system which you will never use. So, distribute them wisely.
Good luck!

You're welcome.
You can download not only the apks, but the client of those third-party markets. For instance, here's a link introducing 1mobile.com's client: http://www.1mobile.com/app/market/?cid=9
Directly download link: http://f.1mobile.com/mobile_software/channel/1MobileMarket_c.apk
It's similar to play store and may notify you if there's an update of one of your installed apps. Try app clients made by various websites repeatedly to find out the best.
Also, try some android PC suites which let you to update android apps via PC.

[Q] Sharing apps without certificate?

Hello,
Is there a way to share some gear s applications here, on the forum, without going through the whole process of submitting to samsung apps?
When I started to test on gear s I had to request a certificate with my gear uid and that means somebody else can't install the application on his watch.
Thanks!
Playstore.
U can put Gear D apps on the Google Playstore.
And will this work 100%? I kinda doubt that the Gear S application will be signed and able to install on the watch if it is posted on Google Play and not in Samsung Store.
