Pygmy collection application Part 1 (Account kit) - Huawei Developers

Introduction​
Great things always take time. So this blog will be a little lengthy to convey you in a better way. I'll cover the following things
1. Application basic introduction.
2. Huawei Account kit integration.
While building this application I'll write series of article.
1. Application basic Introduction
What is the Pygmy Collection?​Let us understand the meaning.
Daily Deposit Scheme is a monetary deposit scheme introduced to help daily wage earners, small traders to inculcate saving habits and also as a way of funding their bigger capital requirements. In this scheme money can be deposited into an account on a daily basis. The amount may be as small as Rupees 20/-. The unique characteristic of this scheme is that an agent from the bank collects money to be deposited, on a daily basis, from the doorsteps of the account holder. It has provided many employment opportunities as agents.
Features of the scheme?​
Choice to opt for Scheme Period from 12, 24, 36 months.
Amount as low as Rs.10 per day can be saved daily/weekly/monthly.
Benefit of this scheme is for small shopkeepers, salesmen, hawkers, etc.
No penalty even if the depositor is unable to pay a contribution regularly.
Deposit accounts can be closed prematurely subject to certain conditions.
Loans can be availed upto a maximum of 85% of the balance in the Pigmy account.
Nomination facility available.
No tax will be deducted for the interest on the deposit. (for Members Only)
The rates of interest are fixed by the Bank from time to time.
If the amount is withdrawn before 6 months then a premature deduction @ 5% will be made from the deposit amount.
Account Holder can withdraw the amount after 6 months without penalty. After completion of 1 year, interest at 2% p.a., Upto 2 year interest 3% p.a., for 3 years interest 5% p.a. will be paid to the account holder.
What does this application do?​This product aims to automate the Pygmy deposit scheme in credit societies for small savers. As we see a lot of fraudulent activities in payment collectives from collection agents, the idea is to design a full proof system which involves less human effort. Credit Societies can automate their collection process by introducing generic hand-held devices for our concern, android mobile, to their field Collection Agents i.e., Cash Collectors for better control, visibility and end-Customer experience. In this application the cash collector can view the customer list where he wants to go for collection with their detailed address and also the collection plan of the customer. Collection information is sent immediately to the Credit Society server and also the customer gets a confirmation message as soon as he makes payment to the cash collector with details of the total collection amount till date. Cash collector can view the complete collection sheet of each customer at the end of month so that he will cross check it with the system and the customer. This entire system will have a web-based background for maintaining depositional transactional history.
It is basically a finance application where agents will go and collect X amount of money from the shops. So that X amount will be saved in the shopkeeper's savings account. Even shopkeepers can also get the loan from the finance.
Nowadays India is moving towards digital but most of the Finances are still using manual processes, where they are going with pen and paper to collect the money. But in fact the shopkeepers are not getting any messages when they pay money to the finance agent, they are not able to see the balances. And in the pen and paperwork there is not much transparency. In the project we are trying to avoid all the manual work.
One tree can produce approximately 10k to 20k papers. Imagine if we make the process digital we can save trees and the environment will be safe.
Advantages​1. Building an application to avoid pen and paperwork.
2. Maintain transparency in the account information.
3. Reduces the time and avoids fraud in the account.
4. Handling security in the application.
5. Scan and receive the amount.
6. Send an amount received as a confirmation message to shopkeepers.
7. Direction to all the shops when new agents join, there will not be much issue to travel to all the shops.
8. Report day/week/month wise.
9. Sending an everyday report to the manager.
10. Save paper and save the environment.
Software and Hardware Requirement​
OS: Windows/Ubuntu/Mac
RAM: 8 GB
Storage 40 GB
IDE: Android Studio
Language: Java
Home items detailed description
New Account opening
This is where a pygmy collection agent or manager of Finance can open a customer account using some customer basic information like First name, Last name, mobile number, Shop name, Account number(Currently its manual just to support existing finance business), Opening balance, Gender, Account type, Scheme type, address and document.
Collection
Agents can collect money from customers using account search or by scanning QR code. When an agent searches for an account number or scans the QR code all customer information has been shown and the agent can enter the amount and collect money.
Report
Here the agent can get the report by daily or monthly and custom report. He can get the report between dates and the report can be exported to pdf and it can be shared with the manager to make it transparent.
Add Member: New agents can be added in this section.
KYC update
If any customer KYC is pending, the agent can take a photo or select it from the gallery and get the type of document and document number and the agent can verify the customer KYC.
Employee profile
Agent detail will be shown in this screen.
Generate QR Code
Agents can generate QR codes for each customer and take a printout and paste in the shop. Whenever an agent goes for collection he doesn't need to ask for an account number and details; he can directly scan to get the customer details. The QR code will be saved under the eCollection folder inside the external storage.
Mini Statement
In this section the agent can get the mini statement for any customer. It shows the full report of that customer and he can export it as a pdf and share it with detailed transaction details with the customer to make it transparent.
2. Huawei Account Kit integration.
HMS (Huawei mobile services)
HMS core (Huawei Mobile Services) opens a wide range of services to application developers. It offers basic services such as logging in with Huawei ID, payment services and push notifications. In addition, HMS core provides various advanced features, such as, positioning, map, machine learning, and games that provide a better experience to Huawei users.
HMS Account Kit provides you with simple, secure, and quick sign-in and authorization functions. Instead of entering accounts and passwords and waiting for authentication, users can just tap the Sign in with HUAWEI ID button to quickly and securely sign in to your app with their HUAWEI IDs.
Using Huawei Account Kit, users can quickly and securely sign in to the application, and the first-time user needs to authorize the application and then, the user has the ability to sign in to the app with one tap using Huawei ID. Huawei facilitates app developers to use the Account Kit on multiple device types such as phones, tablets, and smart screens.

<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
7. Sync the project.
Let us write code.
Java:
private void huaweiLogin() {
AccountAuthParams authParams = new AccountAuthParamsHelper(AccountAuthParams.DEFAULT_AUTH_REQUEST_PARAM).setIdToken().createParams();
AccountAuthService service = AccountAuthManager.getService(LoginActivity.this, authParams);
startActivityForResult(service.getSignInIntent(), 8888);
}
@Override
protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
// Process the authorization result and obtain an ID token from AuthAccount.
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 8888) {
Task<AuthAccount> authAccountTask = AccountAuthManager.parseAuthResultFromIntent(data);
if (authAccountTask.isSuccessful()) {
// The sign-in is successful, and the user's ID information and ID token are obtained.
AuthAccount authAccount = authAccountTask.getResult();
Log.i(TAG, "idToken:" + authAccount.getIdToken());
Toast.makeText(this, "Welcome " + authAccount.getDisplayName() + " We need more data for registration please help us with it.", Toast.LENGTH_LONG).show();
PygmyAgentEntity agent = PygmyDatabase.getDatabase(LoginActivity.this).agentDao().findAgent(authAccount.getEmail());
if (agent == null) {
PygmyNavigator.navigateToRegisterScreenWithData(this, authAccount.getDisplayName(), authAccount.getEmail());
} else {
UserDataUtils.saveUserPhoneNumber(this, agent.getMobileNumber());
UserDataUtils.saveUserPassword(this, agent.getPassword());
UserDataUtils.saveUserLoggedIn(this, true);
UserDataUtils.saveUserData(this, new Gson().toJson(agent));
PygmyNavigator.navigateToWelcomeScreen(this);
finish();
}
} else {
// The sign-in failed. No processing is required. Logs are recorded for fault locating.
Log.e(TAG, "sign in failed : " + ((ApiException) authAccountTask.getException()).getStatusCode());
}
}
}
