Mais je reçois cette erreur dans la console

http://www.example.com:8000/beet.ogg
http://www.example.com:8000/mouthorgan.mp3
http://www.example.com:8000/live

Le son est en cours de lecture, mais après cette erreur, cela prend environ 30 secondes. Parfois, cela prend trop de temps .... Lorsque je joue, il affiche cette erreur, puis sa connexion au serveur ..

aidez-moi s'il vous plaît à résoudre ce problème

Answer 1

Java.io.FileNotFoundException: Aucun fournisseur de contenu: http://www.example.com:8000/live.ogg

Parce que sa tentative de chargement en tant que fichier de fournisseur de contenu de périphérique en fonction du contexte et que vous passez en tant qu'URL.

Il semble que votre problème réside dans la définition de la source de données sur mediaplayer. Pendant que vous essayez de lire l’URL ou la diffusion qui nécessite la méthode setDataSource sans contexte.

Je faisais face au même problème lorsque je jouais en streaming en direct. et ci-dessous le code a résolu mon problème.

Answer 2

Accéder à ce fichier https://github.com/Old-Geek/Radio/blob/master/app/src/main/Java/org/oucho/radio/Player.Java#L234 et modifier 

player.setDataSource(context, Uri.parse(url));

à

player.setDataSource(url)

Le problème est que void setDataSource (String path) Définit la source de données (chemin du fichier ou URL http/rtsp) à utiliser. 

path String: le chemin du fichier ou l'URL http/rtsp du flux que vous souhaitez lire.

le code github utilise void setDataSource (Context context, Uri uri) qui suppose que uri est d'une forme quelconque de ContentProvider

contexte contexte: le contexte à utiliser lors de la résolution de l'URI
uri Uri: l'URI de contenu des données que vous voulez lire

Answer 3

Sur Android 9+, le trafic http net en réseau peut être à l'origine de ce problème. Cochez cette case: Android 8: Le trafic HTTP Cleartext n'est pas autorisé

Answer 4

Cette erreur se produit également si cette autorisation Internet n'est pas dans le fichier Manifest.xml.

<uses-permission Android:name="Android.permission.INTERNET" />
