• Generates boilerplate code for OnActivityResult callbacks and lets you focus on what matters.
• Generated code is fully traceable and debuggable.
• Everything is generated during compile time with appropriate errors / warnings.
• No reflection used!

buildscript {
    dependencies {
        classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'
    }
}

apply plugin: 'com.neenbedankt.android-apt'

dependencies {
    compile 'com.vanniktech:onactivityresult:0.1.0'
    apt 'com.vanniktech:onactivityresult-compiler:0.1.0'

Modules are located on Maven Central.

Override onActivityResult in your Activity / Fragment and call ActivityResult.onResult

@Override
protected void onActivityResult(final int requestCode, final int resultCode, final Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    ActivityResult.onResult(requestCode, resultCode, data).into(this);
}

Annotate your methods and get the callback

@OnActivityResult(requestCode = 33)
void onActivityResultTestActivity() { /* Do something */ }

@OnActivityResult(requestCode = 1, resultCodes = { Activity.RESULT_OK })
void onActivityResultActivityOk() { /* Only do something when ok */ }

@OnActivityResult(requestCode = 1, resultCodes = { Activity.RESULT_CANCELED })
void onActivityResultActivityCanceled() { /* Only do something when canceled */ }

@OnActivityResult(requestCode = 2)
void onActivityResultPickImage(final int resultCode, final Intent intent) { /* Do something */ }

Various parameters are supported:

• none
• int
• Intent
• int, Intent
• Intent, int

Where int parameters will get the resultCode and Intent parameters will get the Intent. Note: Each annotated method shall only have one int and / or Intent variable.

In addition to that other parameter annotations are supported like:

• @IntentData Uri uri. Since 0.2.0

See more examples here.

• Gives you compile error(s) when using invalid RequestCode
• Annotated method does not require resultCode & Intent to be present. It'll work with every combination (no params, resultCode, Intent, resultCode & Intent, Intent & resultCode)
• The annotations are on mavenCentral
• More detailed error messages
• Almost 100% unit test coverage
• Inheritance support
• @IntentData annotation. Since 0.2.0
• Specify resultCodes with e.g. resultCodes = { Activity.RESULT_OK }. Since 0.2.0
