Without the needs of developing private key management and wallet functions. 5 | 6 | ## Get Started 7 | 8 | ### Add dependency 9 | In ```build.gradle``` file，add the following line in ```dependencies```: 10 | ```groovy 11 | implementation 'com.cobo:sdk:1.0' 12 | ``` 13 | 14 | ### Initialize CoboSDK 15 | ```java 16 | CoboSDK.getInstance().initialize(this); 17 | ``` 18 | 19 | ### Handling callbacks 20 | 1. Add `CBEntryActivity` 21 | 22 | Create a `coboapi` package under your application package. Then create a new android activity named `CBEntryActivity` in `coboapi` package. 23 | 24 | ![Add Entry Activity](entry-activity.png) 25 | 26 | Add ```android:exported="true"``` and ```android:launchMode="singleTask"``` properties to ```CBEntryActivity``` in AndroidManifest.xml. 27 | 28 | ```xml 29 | 33 | ``` 34 | 35 | 2. Implement `onCreate` method in `CBEntryActivity` 36 | 37 | ```java 38 | @Override 39 | protected void onCreate(Bundle savedInstanceState) { 40 | super.onCreate(savedInstanceState); 41 | setContentView(R.layout.activity_cbentry); 42 | 43 | Intent intent = getIntent(); 44 | CoboSDK.getInstance().handleIntent(intent); 45 | finish(); 46 | } 47 | ``` 48 | 49 | ## Usage 50 | 51 | ### Sign message 52 | ```java 53 | final String message = "Hello Cobo!"; 54 | CoboSDK.getInstance().signMessage(message, new SignMessageAction.ResultHandler() { 55 | @Override 56 | public void onResult(SignMessageResult result) { 57 | Log.i("DEMO", "result: " + result.address); 58 | boolean match = CoboSDK.getInstance().verifyMessage(result.address, result.signature, message); 59 | Log.i("DEMO", "match: " + match); 60 | } 61 | 62 | @Override 63 | public void onError(int code, String message) { 64 | Log.e("DEMO", "error: " + code + " message: " + message); 65 | } 66 | }, this); 67 | ``` 68 | 69 | ### Send transaction 70 | ```java 71 | BigInteger gasPrice = new BigInteger("1000000000"); // 1 Gwei 72 | BigInteger gasLimit = new BigInteger("21000"); 73 | BigInteger value = new BigInteger("1000000000000000000"); // 1 ETH 74 | String from = 75 | String to = 76 | RawTransaction tx = RawTransaction.createTransaction(null, gasPrice, gasLimit, to, value, null); 77 | CoboSDK.getInstance().sendTransaction(tx, from, new SignTransactionAction.ResultHandler() { 78 | @Override 79 | public void onResult(SignTransactionResult result) { 80 | Log.i("DEMO", "result: " + result.hash); 81 | } 82 | 83 | @Override 84 | public void onError(int code, String message) { 85 | Log.e("DEMO", "error: " + code + " message: " + message); 86 | } 87 | }, this); 88 | ``` 89 | 90 | For more use cases please refer to the ```Example``` project. -------------------------------------------------------------------------------- /Docs/entry-activity.png:
