the usual “something with kotlin doesn’t work” check list:
  • Kotlin Plugin up to date?
  • Gradle Plugin up to date?
  • Kotlin version up to date?
  • only use kapt for annotation processing (don't mix Android Studio's annotationProcessor, apt and kapt, or any other processor)
  • use kapt3 by using apply plugin: 'kotlin-kapt'
  • don’t use kapt { generateStubs true } } at all, it will not work with kapt3
  • using databinding? then databinding compiler version needs to be the same as gradle plugin version ( kapt "com.android.databinding:compiler:$version")

Additionally, I stick to org.jetbrains.kotlin:kotlin-stdlib and don’t use the jre7 version

Useful to explain the differences of the three approaches.
fun printString(string: String) = println(string)
/**
* Prints successfully
*/
Observable.just("Test string")
.doOnNext{ printString(it) }
.subscribe()

lmller / SuggestionsCorrector for Samsung
Last active August 29, 2017 14:59
Samsung Devices ignore TYPE_TEXT_FLAG_NO_SUGGESTIONS, so TYPE_TEXT_VARIATION_VISIBLE_PASSWORD is the only thing that works for them.
public class SuggestionsCorrector {
public static final String SAMSUNG = "samsung";
public EditText correctSuggestions(EditText editText) {
if(Build.BRAND.equalsIgnoreCase(SAMSUNG)) {
editText.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_VISIBLE_PASSWORD);
}
return editText;
