Android Media Stream Error? java.io.FileNotFoundException: no hay proveedor de contenido: http://

Question

Seguí this para Play Stream Radio en Android

Aquí está funcionando bien, pero el reproductor carga poco después de hacer clic. Necesito esperar más de 30 segundos.

Pero estoy recibiendo este error en la consola

por favor ayúdame a arreglar esto

Answer 1

java.io.FileNotFoundException: no hay proveedor de contenido: http://www.example.com:8000/live.ogg

Debido a que se está cargando como un archivo desde el dispositivo, el proveedor de contenido se basa en el contexto y se pasa como una URL.

Parece que su problema está en la configuración de la fuente de datos para el reproductor multimedia. Mientras intenta reproducir la url o la transmisión, lo que se requiere para el método setDataSource sin contexto.

Estaba enfrentando el mismo problema mientras jugaba en vivo. y debajo del código resolví mi problema.

Déjame saber si algo

Answer 2

En Android 9+, el tráfico claro de http net puede causar este problema. Marque este: Android 8: No se permite el tráfico HTTP de texto claro

Answer 3

Este error también ocurre si este permiso de Internet no está en el Manifest.xml

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

Answer 4

Vaya a este archivo https://github.com/Old-Geek/Radio/blob/master/app/src/main/java/org/oucho/radio/Player.java#L234 y cambie

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

a

player.setDataSource(url)

El problema es que void setDataSource (String path) establece el origen de datos (ruta de archivo o URL de http / rtsp) que se va a usar.

cadena de ruta: la ruta del archivo o la URL http / rtsp de la secuencia que desea reproducir

el código github usa void setDataSource (Context context, Uri uri) que asume que uri es de alguna forma de ContentProvider

contexto Contexto: el contexto a usar al resolver el Uri
uri Uri: la URI de contenido de los datos que desea reproducir
