Android Studio 2.3.3, Java 8
I create Android app for Android 4.0+
In my app/build.gradle:
...
minSdkVersion 15
targetSdkVersion 26
I want to use default interface implementation (from Java 8). So I create the tnext class:
public interface DefaultCallback {
public default void onResponse(Call<T> var1, Response<T> var2) {
}
}
but I get compile error:
Default method required API level 24 (current min is 15)
So the question is:
Can I use deafult interface implementation on Android < API 24?
dboof :
Depending on what your minSdk version is you may need to add the following to your app's or module's build.gradle file:
android {
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
}
