# jPromise
`jPromise` is a simple util for async task programming in android develop. Just enjoy async task program in JS way!
## ~~Bad Format~~
```java
Lg.e("第一个任务开始了");
mHandler.postDelayed(new Runnable() {
@Override
public void run() {
Lg.e("第一个任务结束了");
Lg.e("第二个任务开始了, data = " + 1);
mHandler.postDelayed(new Runnable() {
@Override
public void run() {
Lg.e("第二个任务结束了");
Lg.e("第三个任务开始了, data = " + "second");
mHandler.postDelayed(new Runnable() {
@Override
public void run() {
Lg.e("第三个任务结束了， 异步任务完成");
}
}, 2000);
}
}, 2000);
}
}, 2000);
```
## Do it in promise way
```java
final String clientId = UUID.randomUUID().toString();
Promise.start("Some Group Name", new Starter() {
@Override
public void onStart(@NonNull final Return start) {
new Handler().postDelayed(new Runnable() {
@Override
public void run() {
start.next(1001);
}
}, 1_000);
}
}).then("some step description here", new Task() {
@Override
public void onTask(Integer data, @NonNull final Return ret) {
Log.d("MainActivity", "client id is " + clientId);
Log.d("MainActivity", "data from last step is " + data);
new Handler().postDelayed(new Runnable() {
@Override
public void run() {
ret.next(null);
}
}, 1_000);
}
}).then(new Task() {
@Override
public void onTask(@Nullable String nullable, @NonNull Return ret) {
Log.d("DemoActivity", "data from last step is " + nullable);
}
}).execute();
```
## Promise for Kotlin (KPromise)
```kotlin
KPromise.start("Some Group Name") { start ->
Handler().postDelayed({
start.next(100)
}, 1000L)
}.then("some step description here") { int, kReturn ->
Log.d("DemoActivity", "data from last step is $int")
Handler().postDelayed({
kReturn.next("some string")
}, 1000L)
}.then { str, kReturn ->
Log.d("DemoActivity", "data from last step is $str")
}.execute()
```
