Sample application of using the Blockchain API (MVP architecture).
Application contains two functions:
- Create wallet in service
- Exchange rates for Bitcoin
Instruction of the installing API service: https://github.com/blockchain/service-my-wallet-v3#installation
In class Constants type your API key:
public abstract class Constants {
public static final String API_KEY = "YOUR-API-KEY";
}
App using java library from Blockchain.
In build.gradle:
dependencies {
compile 'info.blockchain:api:1.1.4'
}
Example use methods from it library .All methods in main thread. For background thread used Rx:
Observable<CreateWalletResponse> createWallet(String email, String password) {
return Observable.fromCallable(() -> CreateWallet.create(
Constants.BASE_URL,
password,
Constants.API_KEY,
null, null,
email))
.observeOn(AndroidSchedulers.mainThread())
.subscribeOn(Schedulers.newThread());
}
Observable<Map<String, Currency>> getExchangeRates() {
return Observable.fromCallable(() -> ExchangeRates.getTicker(Constants.API_KEY))
.observeOn(AndroidSchedulers.mainThread())
.subscribeOn(Schedulers.newThread());
}
For get access need API key.
