I can get data form retrofit form this https://kanjiapi.dev/#!/
data {"kanji":"蛍","grade":8,"stroke_count":11,"meanings":["lightning-bug","firefly"],"kun_readings":["ほたる"],"on_readings":["ケイ"],"name_readings":[],"jlpt":1,"unicode":"86cd","heisig_en":"lightning-bug"}
MainActivity :
val apiService = KanjiService.getInstance()
val call = apiService.getKanji()
call.enqueue(object : Callback<List<Kanji>>{
override fun onResponse(call: Call<List<Kanji>>, response: Response<List<Kanji>>) {
Log.i("API",response.body().toString())
}
override fun onFailure(call: Call<List<Kanji>>, t: Throwable) {
t.message?.let { Log.e("API", it) }
}
})
data class Kanji :
data class Kanji(
val kanji:String,
val grade:Int?=null,
val stroke_count:Int,
val meanings:List<String>,
val heisig_en:String?=null,
val kun_readings:List<String>,
val on_readings:List<String>,
val name_readings:List<String>,
val jlpt:Int?=null,
val unicode:String,)
Kanjiservice :
const val BASE_URL = "https://kanjiapi.dev/v1/"
interface KanjiService {
@GET("kanji/蛍")
fun getKanji(): Call<List<Kanji>>
companion object{
fun getInstance():KanjiService{
return Retrofit.Builder()
.baseUrl(BASE_URL)
.addConverterFactory(GsonConverterFactory.create())
.build()
.create(KanjiService::class.java)
}
}
}
this is the warning : E/API: Expected BEGIN_ARRAY but was BEGIN_OBJECT at line 1 column 2 path $
CodePudding user response:
Your callback is looking for list
from API Response, as you used this; Callback<List<Kanji>
.
First Observe your API Response, It is {}
JsonObject, and you casted it into List
in your API Callback.
So fix this in your API Call like this;
call.enqueue(object : Callback<Kanji>{
override fun onResponse(call: Call<Kanji>, response: Response<Kanji>) {
Log.i("API",response.body().toString())
}
override fun onFailure(call: Call<Kanji>, t: Throwable) {
t.message?.let { Log.e("API", it) }
}
})
also modify your Interface;
@GET("kanji/蛍")
fun getKanji(): Call<Kanji>
