Question

I just updated my Android Studio to version 3.2 and followed instructions to use androidx.

I\'ve been using a Youtube fragment inside a Fragment activity and everyth

Answer 1

Many thanks to both @Hosszuful and @Mehdi. I have followed your advice and it worked very nicely.

A few weeks after I asked this question I "translated" my app to Kotlin and, therefore, I tried to translate your answer as well.

This is what I ended up with and it's working for me.

package com.google.android.youtube.player //<--- IMPORTANT!!!!

import android.os.Bundle
import android.view.LayoutInflater
import android.view.ViewGroup
import androidx.fragment.app.Fragment
import com.google.android.youtube.player.internal.ab
import java.util.*

class YouTubePlayerSupportFragmentX : Fragment(), YouTubePlayer.Provider {
    private val a = ViewBundle()
    private var b: Bundle? = null
    private var c: YouTubePlayerView? = null
    private var d: String? = null
    private var e: YouTubePlayer.OnInitializedListener? = null
    override fun initialize(var1: String, var2: YouTubePlayer.OnInitializedListener) {
        d = ab.a(var1, "Developer key cannot be null or empty")
        e = var2
        a()
    }

    private fun a() {
        if (c != null && e != null) {
            c?.a(this.activity, this, d, e, b)
            b = null
            e = null
        }
    }

    override fun onCreate(var1: Bundle?) {
        super.onCreate(var1)
        b = var1?.getBundle("YouTubePlayerSupportFragment.KEY_PLAYER_VIEW_STATE")
    }

    override fun onCreateView(var1: LayoutInflater, var2: ViewGroup?, var3: Bundle?): android.view.View? {
        c = YouTubePlayerView(Objects.requireNonNull(this.activity), null, 0, a)
        a()
        return c
    }

    override fun onStart() {
        super.onStart()
        c?.a()
    }

    override fun onResume() {
        super.onResume()
        c?.b()
    }

    override fun onPause() {
        c?.c()
        super.onPause()
    }

    override fun onSaveInstanceState(var1: Bundle) {
        super.onSaveInstanceState(var1)
        (if (c != null) c?.e() else b)?.let { var2 ->
            var1.putBundle("YouTubePlayerSupportFragment.KEY_PLAYER_VIEW_STATE", var2)
        }
    }

    override fun onStop() {
        c?.d()
        super.onStop()
    }

    override fun onDestroyView() {
        this.activity?.let { c?.c(it.isFinishing)  }
        c = null
        super.onDestroyView()
    }

    override fun onDestroy() {
        if (c != null) {
            val var1 = this.activity
            c?.b(var1 == null || var1.isFinishing)
        }
        super.onDestroy()
    }

    private inner class ViewBundle : YouTubePlayerView.b {
        override fun a(var1: YouTubePlayerView, var2: String, var3: YouTubePlayer.OnInitializedListener) {
            e?.let { initialize(var2, it) }
        }

        override fun a(var1: YouTubePlayerView) {}
    }

    companion object {
        fun newInstance(): YouTubePlayerSupportFragmentX {
            return YouTubePlayerSupportFragmentX()
        }
    }
}

There may be better ways to write it down and any help on that regard would be mostly appreciated but, if anyone else was looking for the Kotlin version of this problem's solution, this code should do.

PS: I'm gonna leave @Mehdi's answer as the accepted one because he's also sharing credits with @Hosszuful and because my answer is just the Kotlin version of what they suggest.

Answer 2

I got it working by following code chunk.

Object obj = 
getSupportFragmentManager().findFragmentById(R.id.youtube_player_fragment);
    if (obj instanceof YouTubePlayerSupportFragment)
        youTubePlayerFragment = (YouTubePlayerSupportFragment) obj;

During debugging I found that the fragmentmanager was coming to be instance of YouTubePlayerSupportFragment only. But compiler was not able to cast it when I would write

(YouTubePlayerSupportFragment) 
getSupportFragmentManager().findFragmentById(R.id.youtube_player_fragment);

The above code chunk (instanceof ) worked fine.

Answer 3

Just copy the original java file (com.google.android.youtube.player.YouTubePlayerFragment) to your project to the same package but different class name etc. com.google.android.youtube.player.YouTubePlayerFragmentX, and update the extends class from android.app.Fragment to androidx.fragment.app.Fragment.

The implementation is the same:

YouTubePlayerFragmentX youTubePlayerFragment = YouTubePlayerFragmentX.newInstance();
FragmentTransaction transaction = getChildFragmentManager().beginTransaction();
transaction.add(R.id.youtube_fragment, youTubePlayerFragment).commit();

Tested... it's working.

Answer 4

Replace .add

transaction.add(R.id.youtube_fragment, youTubePlayerFragment).commit();

with this .replace

transaction.replace(R.id.youtube_fragment, youTubePlayerFragment).commit();

and copy this class to your project folder (it may need to create the following folders)

java -> com -> google -> android -> youtube -> player -> (here name of) YouTubePlayerSupportFragmentX.java

then in code replace

YouTubePlayerSupportFragment to YouTubePlayerSupportFragmentX.

Answer 5

I've fixed it by following the @Hosszful answer, I made it easy by just using this file, https://gist.github.com/medyo/f226b967213c3b8ec6f6bebb5338a492

Answer 6

Just use transaction.replace. Ignore the error, it'll work. Google hasn't refactored youtube api library to androidx yet.
