What is TedOnActivityResult

When we use startActivityForResult(), we have to receive result/data in onActivityResult().

 @Override
  protected void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    ...
    
    startActivityForResult(intent,REQ_CODE_AAA);
    
  }

  @Override
  protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    switch (requestCode){
      case REQ_CODE_AAA:
        if(resultCode==RESULT_OK){
          doSomething();
        }
        break;
      default:
        super.onActivityResult(requestCode, resultCode, data);    
    }
    
  }

This is very complex and inconvenience to us.

If you use Coroutines, you want synchronized like this.

val activityResult: ActivityResult = TedOnActivityResult.with().startActivityForResult(intent)

If you use RxJava, you want chaining like this.

  AA()
  .filter(...)
  .subscribeOn(...)
  .observeOn(...)
  .subscribe(...);

TedOnActivityResult can make startActivityForResult() chaining.

Setup

• Edit root/app/build.gradle like below.
• You can choose only one library depend on your code style normal/coroutine/rxJava1/rxJava2
• Replace x.y.z with the version shown in the 'Maven Central' button below, or the specific version you want (e.g. replace x.y.z with 3.3.0 if you want v3.3.0).

repositories {
  google()
  mavenCentral()
}

dependencies {
    // Normal
    implementation 'io.github.ParkSangGwon:tedonactivityresult:x.y.z'
    
    // Coroutine
    implementation 'io.github.ParkSangGwon:tedonactivityresult-coroutine:x.y.z'

    // RxJava2
    implementation 'io.github.ParkSangGwon:tedonactivityresult-rx1:x.y.z'
    // RxJava3
    implementation 'io.github.ParkSangGwon:tedonactivityresult-rx2:x.y.z'
}

How to use

Normal

Also you can use OnActivityResultListener not RxJava's chaining style

TedOnActivityResult.with(this)
    .setIntent(intent)
    .setListener((resultCode, data) -> {
       if (resultCode == RESULT_OK) {
        String name = data.getStringExtra(SampleActivity.EXTRA_NAME);
        int age = data.getIntExtra(SampleActivity.EXTRA_AGE, -1);
      }

    })
    .startActivityForResult();

Coroutine

If you use kotlin and coroutine, You can use suspend function.

val activityResult: ActivityResult = TedOnActivityResult.with(this).startActivityForResult(intent)

RxJava

RxJava1/RxJava2 can write code like this.

TedRxOnActivityResult.with(this)
    .startActivityForResult(intent)
    .subscribeOn(...)
    .observeOn(...)
    .subscribe(activityResult -> {

      if (activityResult.getResultCode() == RESULT_OK) {
        Intent data = activityResult.getData();
        String name = data.getStringExtra(SampleActivity.EXTRA_NAME);
        int age = data.getIntExtra(SampleActivity.EXTRA_AGE, -1);
      }

    });
