|
A Java library for mobile app Developers; Graphene/Bitshares blockchain.
|
|
|
|
## Usage
|
|
|
|
In your root build.gradle, add this if you don't already have it.
|
|
|
|
```Groovy
|
|
allprojects {
|
|
repositories {
|
|
jcenter()
|
|
}
|
|
}
|
|
```
|
|
|
|
In your app module, add the following dependency:
|
|
|
|
```Groovy
|
|
dependencies {
|
|
compile 'com.github.bilthon:graphenej:0.4.2'
|
|
}
|
|
```
|
|
|
|
## Example
|
|
|
|
### Very simple funds transfer
|
|
|
|
This is a simple transfer operation of 1 BTS from account **bilthon-15** to **bilthon-5**
|
|
```java
|
|
// Creating a transfer operation
|
|
TransferOperation transferOperation = new TransferOperationBuilder()
|
|
.setTransferAmount(new AssetAmount(UnsignedLong.valueOf(100000), new Asset("1.3.0")))
|
|
.setSource(new UserAccount("1.2.143563")) // bilthon-15
|
|
.setDestination(new UserAccount("1.2.139313")) // bilthon-5
|
|
.setFee(new AssetAmount(UnsignedLong.valueOf(264174), new Asset("1.3.0")))
|
|
.build();
|
|
|
|
// Adding operations to the operation list
|
|
ArrayList<BaseOperation> operationList = new ArrayList<>();
|
|
operationList.add(transferOperation);
|
|
|
|
// Creating a transaction instance
|
|
Transaction transaction = new Transaction(sourcePrivateKey, null, operationList);
|
|
```
|
|
|
|
From here on out, it is just a matter of creating a websocket connection and using a custom handler called
|
|
```TransactionBroadcastSequence``` in order to broadcast it to the witness node.
|
|
|
|
```java
|
|
// Setting up a secure websocket connection.
|
|
SSLContext context = null;
|
|
context = NaiveSSLContext.getInstance("TLS");
|
|
WebSocketFactory factory = new WebSocketFactory();
|
|
factory.setSSLContext(context);
|
|
|
|
WebSocket mWebSocket = factory.createSocket(FULL_NODE_URL);
|
|
|
|
mWebSocket.addListener(new TransactionBroadcastSequence(transaction, new Asset("1.3.0"), listener));
|
|
mWebSocket.connect();
|
|
```
|
|
|
|
The provided ```listener``` is an instance of the class ```WitnessResponseListener```.
