What is the naming convention for android apps?
I just kicked off my 1st cordova app and out of the box it is named com.example.hello..
If my app is called "guitars" can the id not just be that?
From: Android - Package Name convention
I understand the company name coming 1st.. but i don't follow why com is preceding it
Android apps have always been named like this. It comes from Java naming. If you have an app named "guitars" it would show as com.john.guitars
Com = commercial application (just like .com, most people register their app as a com app)
First level = always the publishing entity's' name
Second level (optional) = sub-devison, group, or project name
Final level = product name
In Android, in order to get a unique identifier you need to put something that is unique to your app, and here comes your domain into place since there is only one domain with the same name, like email for example.
This will help the device recognize your app. The reason for com at the beggining is because its an old convinient from java, it helps group apps in the same place. You can of course still do org.my.domain and it will work the same but will be in a different "folder" on the device.
So the naming convention is just your domain upside down + the name of the app, There for, guitars will be in the end if the name of the app is Guitars.
The appId can be any string. So you can set it to whatever you want, including just "guitars". However, the appId must be unique on a device. If another app that is already installed has the appId as "guitars" then your app will not install. To help avoid this, Google recommends that you use a "reverse domain name". For companies that already own a domain this can help avoid name collisions since com.google is "owned" by Google and com.samsung is clearly from Samsung.
This practice comes from using reverse domain names for Java packages. See What is the significance of the reverse domain name for java package structure for an explanation.
How do I open the Huawei AppGallery that points to a specific app directly?
I know that is possibile to do it natively in Android, but I need to do it with plain Javascript for a Cordova application
You can refer to the following:
The typical link format of the application details page on Huawei AppGallery is: https://appgallery.cloud.huawei.com/appDetail?pkgName=**packagename**&channelId=**channelid**&referrer=**referrer**&detailType=0&calltype=AGDLINK
Parameter description:
Packagename: required, the package name to be popularized and applied, such as com.huawei.gamebox ..
Channelid: It is recommended to fill in. To improve the channel identification degree of data analysis, it is recommended to fill in the designated identification number for each channel. If it is not filled in, the system will automatically read the package name of the source media, but the package name cannot be obtained by jumping through the webpage or offline QR code.
Referrer: not required; if not, it will be blank by default. This parameter refers to the secondary channel number. When links are posted on multiple pages (scenes) of the same media, the specific location effect of the media can be identified by the secondary channel number.
DetailType=0&calltype=AGDLINK: basic parameter, which cannot be deleted.
for example: https://appgallery.cloud.huawei.com/appDetail?pkgName=com.huawei.gamebox&channelId=ceshi&referrer=01&detailType=0&calltype=AGDLINK
I think the shortest and easiest one would be running this simple link:
https://appgallery.cloud.huawei.com/ag/n/app/<YOUR_APP_ID>
No need Packagename, Channelid and stuffs like that and no need to config anything and the rest will handled by Huawei automatically.
How to get YOUR_APP_ID?
Go to Huawei App Gallery
Search for your app (e.g. WeChat)
Copy the ID in the end of the link (e.g. https://appgallery.huawei.com/#/app/C5683)
In this case the APP_ID for WeChat would be C5683
So the Huawei app link for WeChat would be https://appgallery.cloud.huawei.com/ag/n/app/C5683
Hope this helps! Enjoy~
The documentation link: https://developer.squareup.com/docs/pos-api/build-mobile-web#step-5-test-your-code suggest straight forward code like this:
<a href="intent:#Intent;
action=com.squareup.pos.action.CHARGE;
package=com.squareup;
S.browser_fallback_url=https://my.website.com/index.html;
S.com.squareup.pos.WEB_CALLBACK_URI=https://my.website.com/index.html;
S.com.squareup.pos.CLIENT_ID=sq0ids-yourClientId;
S.com.squareup.pos.API_VERSION=v2.0;
i.com.squareup.pos.TOTAL_AMOUNT=100;
S.com.squareup.pos.CURRENCY_CODE=USD;
S.com.squareup.pos.TENDER_TYPES=com.squareup.pos.TENDER_CARD,com.squareup.pos.TENDER_CASH;
end">Start Transaction</a>
I tested it and it does not open any link, my devide already have app installed.
When I try this code:
Take a QR code 2
It open play store app with squareup pos app information, I need to directly open the app and not play store screen of the app, is there any way?
*UPDATE:
I got transactions to work after adding S.com.squareup.pos.LOCATION_ID={{ my_location_id }}. The location ID can be found in Square Developer Portal > Locations. Also if the POS app is passcode protected, you have to open and login with passcode before sending transaction.
*END UPDATE
I've been working through this same issue. I still haven't gotten a transaction to work, but have at least gotten the app to open.
Make sure the CLIENT ID is your production application ID. NOT sandbox.
The WEB_CALLBACK_URI needs to match the Web Callback URL defined in your Square Developer Portal > Point Of Sale API.
I hope this helps. If you do figure this out and get transactions to work, please post your solution for me and others who are sure to run into this issue since the documentation is lacking.
I recently came across this app Purchase Apps, which is somehow able to retrieve apps I've paid for in google play after I signed in using my google account.
I'm trying to find out how it is being done as I want to build a similar app, but for the free apps which were downloaded.
However, I can't find which OAuth API Scope was used for retrieving that information, even after going through the entire list of APIs.
EDIT:
I'm putting a new bounty on this question, as suggested by a similar question I've asked about here, and because here and there I don't see a real answer about how to do it, and what can be done with it.
I'd like to refine the questions into multiple pieces:
What is the API that can be used to get information of purchased apps? Where can I read about it? Please show a full, working example of how to do it.
Can it do more ? Maybe perform search? Maybe show free apps that were installed? Maybe the time they were installed and uninstalled? And the categories of those apps?
Are there any special requirements for using this API ?
EDIT: I'm putting a max bounty on this, because no matter how much I've read and tried, I still failed to make a POC that can query the apps from the Play Store that the user has ever downloaded (name, package name, date installed and/or removed, icon URL, price...), including both paid and free apps.
If anyone finds a working sample, show how it's done, and also show how you've found about it (documentation or anything that has led you to the solution). I can't find it anywhere, and the current solutions here are too vague for me to start from.
Issue is resolved. The exploit has been closed.
We will be closing this bug due to being logged in a Preview version of Android. If the issue is still relevant and reproducible in the latest public release (Android Q), please capture a bugreport and log the bug in https://source.android.com/setup/contribute/report-bugs. If a reply is not received within the next 14 days, this issue will be closed. Thank you for your understanding.
Latest update:
This is a bug and Google will address it in the next update.
We've deferred this issue for consideration in a future release. Thank
you for your time to make Android better
This answer has turned into a conglomeration of ideas and been edited to include information from discussion in the comments.
The androidmarket api, would be a customised api written by the developer. It's not available to the public.
To address your concerns in the comments. The developer would have utilised the current apis available through Android Developer and Google to create a project that manages all of these.
As for accessing Full Account Access, I'm not sure exactly how these developers have achieved this.
I'd recommend using the AccountManager, which is part of android.accounts, has access to credentials and a method getUserData. The account manager has access to passwords and is capable of creating and deleting accounts. This, possibly used with Content Provider
See Udinic/SyncAdapter Authentication.
To reply to your comment:
This blog should help you to get started. Write your own Android Authenticator.
How these apps actually work, I cannot tell you. They may also have different implementations (unless they're a collaborative effort behind the scenes, they most certainly will be different).
One guess. Firstly use GoogleSignInAccount with com.google.android.gms.auth.api.signin.
There a definition for scope, to determine the extent of the permissions the app is granted.
Using requestScopes(), the
public static final String PROFILE
.../ It lets your web app access over-the-air Android app installs.
For example:
GoogleSignInOptions gso =
new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
.requestEmail().
.requestScopes(new Scope("https://www.googleapis.com/auth/contacts.readonly"))
.build();
If full access can be gained a list of all apps used by the account holder can be found and compared to what's on the device.
Package Manager will retrieve a list of all apps currently installed on the device.
PackageInfo provides the details about the app.
INSTALL_REASON_USER will also filter out apps that have been actively installed by the user.
You might want to look at com.google.firebase.appindexing and Log User Actions. Different actions can be tracked.
The users account history is found at https://myactivity.google.com/myactivity.
A helpful link is the OAuth 2.0 Playground.
This github repo node-google-play, using node, is current and will call Google Play APIs. As did the archive that was used as an "unofficial" api, android-market-api, to query the market place.
App 1
The app claims to use the following permissions:
Version 2.1.8 can access:
$ In-app purchases
Other
receive data from Internet
view network connections
full network access
use accounts on the device
prevent device from sleeping
read Google service configuration
Noteworthy, the app doesn't set any permissions when there was a basic, install. I was unable to use any of the features, as I have no paid apps. So for the initial search - there were no permissions needed, which would indicate the app didn't have access to my account.
I checked the permissions - there were none set. So the only thing required was to accept the pop up, as displayed in your question.
App 2
The other app you refer to that does the same thing is more upfront about what is being accessed.
My Paid Apps
SECURITY/PRIVACY NOTICE
The first time you run this app, it will ask for full permission to your Google account. This is unfortunately
the only way to access the required information. No personal
information is stored, no information about your apps is shared with
the developer of this app, nor shared with any third parties.
Everything is kept on your phone only.
I've gone into detail over these apps in this blog post, which was for a university capstone project (no monetary gain). I'm inclined to think this is an exploit in the API and not status by design by Google, as there are no API calls to fetch purchases of apps other than the developer's own app. I hypothesize it's a zero day exploit, in which case there's no legitimate way to access this information.
In case of one of these applications (My Paid Apps), after checking the network traffic it is pretty obvious that it does use the Store's Account page to retrieve the list of paid applications.
Now, the mechanism it uses is the same mechanism that Google Chrome currently, and Pokemon GO supposedly at a point in time used.
In a nutshell, steps to do so are as follow:
Login:
What the mentioned program do for the first step is to log the user in and get access to the user's access token. To do so, it uses the android.accounts.AccountManager.getAuthToken() method. (See more: AccountManager)
However, as for the token scope, oauth2:https://www.google.com/accounts/OAuthLogin is requested.
It might be important to note that based on the OAth2 documentation from Google, this scope is not valid; however, it seems like a valid scope for Google OAuth v1.
Converting the newly retrieved access token to a ubertoken:
Now, what actually ubertoken supposed to do, is unknown and there is no official documentation about it. However, it was seen in the wild to be used by chrome browser to login users.
This is done by requesting the https://accounts.google.com/OAuthLogin?source=ChromiumBrowser&issueuberauth=1 page.
Converting ubertoken to website session:
Later on, using the newly created ubertoken it is possible to get a website session using the https://accounts.google.com/MergeSession API endpoint. After this step, the application is essentially capable of loading all personal pages that you can open using your browser while logged in; except some special pages including Payment settings.
Retrieving the list of paid applications:
Requesting and parsing the https://play.google.com/store/account page.
Following is the application's traffic as captured by 'Packet Capture':
As it is clearly visible in the picture, the end result is identical to what I get when I normally open the store's account page on my PC with Chrome Desktop:
Side note:
It seems none of these endpoints are documented as they are primarily used by Google's own programs and should be considered internal. Therefore I strongly recommend not using them in any program or code that you expect to run for a long time or in a production environment.
Also, there is bad news here for you too, it seems that the Google Play's account page only lists paid applications or special free apps (more especially OEM apps). I will try to find some time and dig deeper into the other application.

Exploiting Google Chrome's OAuth2 Tokens
If you have root access, You can access /data/data/com.android.vending/databases/library.db

Dealing with unofficial Google APIs is incredibly complicated territory. It's going to be possible to get this to work, but that's all I'll say. Proceed at your own risk.
The first thing you're going to need to do is get a Google Play auth token. This can be done several ways, but here's how they do it in Purchased Apps:
public static String getAuthToken(Activity activity, String userEmail) {
AccountManager accountManager = AccountManager.get(activity);
Account userAccount = new Account(userEmail, "com.google");
Bundle options = new Bundle();
options.putBoolean("suppressProgressScreen", true);
String token;
try {
Bundle result = accountManager
.getAuthToken(userAccount, "androidmarket", options, activity, null, null)
.getResult();
token = result.getString("authtoken");
} catch (OperationCanceledException e) {
Log.d(TAG, "Login canceled by user");
return null;
} catch (IOException | AuthenticatorException e) {
Log.e(TAG, "Login failed", e);
return null;
}
return token;
}
A few things to note here:
The above code must be run asynchronously. I recommend RxJava, but an AsyncTask will work.
You must supply a email for the account you want to use. I'll leave the details up to you but this is fairly easy using AccountManager.
After you have an auth token, you can now access any Google Play Store endpoint. The main one used by Purchased Apps is https://android.clients.google.com/fdfe/purchaseHistory. Another one you might be interested in is https://android.clients.google.com/fdfe/details?doc=(package name) (from APKfetch code). Here's a page with some more and some analysis. If you make a request to these APIs, you'll need to supply several headers:
Authorization - "GoogleLogin auth=(your auth token)"
User-Agent - "Android-Finsky/6.4.12.C-all%20%5B0%5D%202744941 (api=3,versionCode=80641200,sdk=" + VERSION.SDK_INT + ",isWideScreen=0)";
X-DFE-Device-Id - your device's Google Services Framework ID, obtained from AdvertisingIdClient.
X-DFE-Client-Id - "am-android-google"
Accept-Language - The device's language code, eg "en".
Now, you need to parse the response. Here's where things get tricky. These APIs returns a message encoded as a Protobuf, so it's essentially just binary data unless you have a schema (which of course, only Google has). One way to go about this in theory is to decompile the Google Play Store app and reuse their generated protobuf models with a tool like JADX.
Unfortunately, I've tried this and it doesn't really work. Protobuf model classes are just too complex for a standard decompiler. What you can use is a tool called PBTK. You'll ideally want to run this on the Google Play Store 6.1.12 APK, since that's the last version before they started using ProGuard. Do note that this program has two errors in its script that need to be fixed before running it: changing 'extracto' to 'extractor' in gui.py and removing the assertion statement on line 500 of jar_extract.py.
Now, that should output all of the response classes as .proto files. Create a folder under src/main called proto and drag the entire generated 'com' directory to it. You can delete everything that's not under com/google/android/finsky/protos. Follow instructions online to setup Gradle with the Protobuf Lite plugin.
When you want to parse a response, you can use the ResponseWrapper class, since they all appear to be contained under that.
That's about as far as I can take you. There's a good chance I got some part of this wrong; JADX is your best friend here, because the best way to figure out what an app is doing is by looking at its code. Hope this helps and happy developing!
you can get the package name of all installed apps on device and then get the information of every installed package that you find in the device from google play without any need to get to user account. there is some third party or unofficial apis to get google play apps details as json by getting the app package name. for example: https://42matters.com/
then use the received information for every package to find free ones.
i have two resources for you to consider, but first, in a word, no. there is no api from GOOGLE to let you do what you want, as these metrics arent stored in the phone, they are on the google play store servors, and google has no OFFICIAL api for the play store. you can however glean some info from these two sites:
https://www.quora.com/Is-there-an-API-for-the-Google-Play-Storeenter link description here
https://android.stackexchange.com/questions/162146/how-to-see-all-the-apps-i-have-downloaded-from-google-play-store
and this is enough to see how to accomplish this.
first, a list of what apps have been downloaded by an account is only referencable by the account. and this can be done through the play store. since your app will be installed on that users phone, this dosnt matter... you're in.
second, you will need a 3rd party API built for the GOOGLE PLAY STORE, there are some out there, check the first link.
using the api of your choice, you will send a get request, to the play store, and in return you should receive in most cases a json object to deserialize.
deserialize the object, and you will have your list. which list you get will depend on the endpoint you use, but that should be explained by/in the API itself.
good luck!
Good day. I'm working on an android program which is application manager. I want to call the application of "Dictionary.com" but in my code, I should include the package and activity name of this application. Can someone post here the Package name and Activity name of this Application? Please. THANK YOU!!!
Application name is something that visible to the user. So put some user friendly name such as "Digital PocketDictionary"
Package name should be unique. It is recommended if you can use your domain in reverse version. As an example, if you have your own hosting or a website related to this app such as www.digitaldic.com you can use com.digital.dictionary as the package name. Make sure all the letters are simple.
It's a little difficult to get what you are asking for, specially the activity name. But here's what you could do to get the package name.
Install the required apps on your phone and then connect it to your computer and in your Eclipse, go to the "DDMS" perspective. In the devices window, click on your phone's entry. On the right, go to the File Explorer.
Go to system/app. You should see the name of the .apk file. You'll get the name of the package in the "info" column.
Getting the name of the activity might be difficult. you could contact Dictionary.com to get the info, coz I doubt you will be able to start the activity, if Dictionary.com doesn't allow it.
I just tried this code and it works without having to include the activity's name:
PackageManager pm = this.getPackageManager();
Intent i = pm.getLaunchIntentForPackage("com.example.test3");
if (!i.equals(null)){
startActivity(i);
}else{
System.out.println("too bad (-*-)");
}
