Medya öğelerinin resimleri, ContentResolver.SCHEME_CONTENT veya ContentResolver.SCHEME_ANDROID_RESOURCE kullanılarak yerel URI olarak iletilmelidir. Bu yerel URI, uygulamanın kaynaklarında bir bit eşleme veya vektör çizilebilir öğesiyle sonuçlanmalıdır. İçerik hiyerarşisindeki öğeleri temsil eden MediaDescriptionCompat nesneleri için URI'yi setIconUri üzerinden iletin.
Oynatılan öğeyi temsil eden MediaMetadataCompat nesneleri için URI'yi putString üzerinden geçirmek üzere şu anahtarlardan herhangi birini kullanın:
Bu adımlarda, bir web URI'sinden resimlerin nasıl indirileceği ve yerel bir URI üzerinden nasıl gösterileceği açıklanmaktadır. Tam bir örnek için Universal Android Music Player örnek uygulamasında openFile ve çevreleyen yöntemlerin uygulanmasına bakın.
Web URI'sine karşılık gelen bir content:// URI'si oluşturun. Medya tarayıcı hizmeti ve medya oturumu, bu içerik URI'sini Android Auto ve Android Automotive OS'e (AAOS) iletir.
Kotlin
funUri.asAlbumArtContentURI():Uri{returnUri.Builder().scheme(ContentResolver.SCHEME_CONTENT).authority(CONTENT_PROVIDER_AUTHORITY).appendPath(this.getPath())// Make sure you trust the URI.build()}
Java
publicstaticUriasAlbumArtContentURI(UriwebUri){returnnewUri.Builder().scheme(ContentResolver.SCHEME_CONTENT).authority(CONTENT_PROVIDER_AUTHORITY).appendPath(webUri.getPath())// Make sure you trust the URI!.build();}
ContentProvider.openFile uygulamanızda, ilgili URI için bir dosyanın olup olmadığını kontrol edin. Aksi takdirde, resim dosyasını indirip önbelleğe alın. Bu kod snippet'inde Glide kullanılıyor.

This local URI must resolve to\neither a bitmap or a vector drawable.\n\n- For `MediaDescriptionCompat` objects representing items in the [content\n hierarchy](/training/cars/media/create-media-browser/content-hierarchy#onLoadChildren), pass the URI through [`setIconUri`](/reference/android/support/v4/media/MediaDescriptionCompat.Builder#setIconUri(android.net.Uri)).\n\n | **Warning:** Don't provide artwork using [`setIconBitmap`](/reference/android/support/v4/media/MediaDescriptionCompat.Builder#setIconUri(android.net.Uri)). While this method is supported on Android Auto, it isn't supported on Android Automotive OS (AAOS). Additionally, including many bitmaps in a result can cause you to exceed the [1MB binder size limit](/guide/components/activities/parcelables-and-bundles#sdbp), causing your app to be unresponsive.\n- For `MediaMetadataCompat` objects representing the [playing item](/media/legacy/mediasession#maintain-state),\n use any of these keys to pass the URI through [`putString`](/reference/android/support/v4/media/MediaMetadataCompat.Builder#putString(java.lang.String,%20java.lang.String)):\n\n - [`MediaMetadataCompat.METADATA_KEY_DISPLAY_ICON_URI`](/reference/android/support/v4/media/MediaMetadataCompat#METADATA_KEY_DISPLAY_ICON_URI())\n - [`MediaMetadataCompat.METADATA_KEY_ART_URI`](/reference/android/support/v4/media/MediaMetadataCompat#METADATA_KEY_ART_URI())\n - [`MediaMetadataCompat.METADATA_KEY_ALBUM_ART_URI`](/reference/android/support/v4/media/MediaMetadataCompat#METADATA_KEY_ALBUM_ART_URI())\n\nProvide artwork from your app's resources\n-----------------------------------------\n\nTo provide drawables from your [app's resources](/guide/topics/resources/providing-resources), pass a URI in the\nfollowing format: \n\n android.resource://\u003cvar translate=\"no\"\u003ePACKAGE_NAME\u003c/var\u003e/\u003cvar translate=\"no\"\u003eRESOURCE_TYPE\u003c/var\u003e/\u003cvar translate=\"no\"\u003eRESOURCE_NAME\u003c/var\u003e\n\n // Example URI - note that there is no file extension at the end of the URI\n android.resource://com.example.app/drawable/example_drawable\n\nThis snippet demonstrates how to create a URI of this format from a resource ID: \n\n val resources = context.resources\n val resourceId: Int = R.drawable.example_drawable\n\n Uri.Builder()\n .scheme(ContentResolver.SCHEME_ANDROID_RESOURCE)\n .authority(resources.getResourcePackageName(resourceId))\n .appendPath(resources.getResourceTypeName(resourceId))\n .appendPath(resources.getResourceEntryName(resourceId))\n .build()\n\nProvide artwork using a content provider\n----------------------------------------\n\nThese steps describe how to download art from a web URI and expose it through a\nlocal URI using a [content provider](/guide/topics/providers/content-provider-creating). For a complete example, see the\n[implementation](https://github.com/android/uamp/blob/99e44c1c5106218c62eff552b64bbc12f1883a22/common/src/main/java/com/example/android/uamp/media/library/AlbumArtContentProvider.kt#L52) of [`openFile`](/reference/android/content/ContentProvider#openFile(android.net.Uri,%20java.lang.String)) and the surrounding methods in the\nUniversal Android Music Player sample app.\n\n1. Build a `content://` URI corresponding to the web URI. The media browser\n service and media session pass this content URI to Android Auto and\n AAOS.\n\n ### Kotlin\n\n fun Uri.asAlbumArtContentURI(): Uri {\n return Uri.Builder()\n .scheme(ContentResolver.SCHEME_CONTENT)\n .authority(CONTENT_PROVIDER_AUTHORITY)\n .appendPath(this.getPath()) // Make sure you trust the URI\n .build()\n }\n\n ### Java\n\n public static Uri asAlbumArtContentURI(Uri webUri) {\n return new Uri.Builder()\n .scheme(ContentResolver.SCHEME_CONTENT)\n .authority(CONTENT_PROVIDER_AUTHORITY)\n .appendPath(webUri.getPath()) // Make sure you trust the URI!\n .build();\n }\n\n2. In your implementation of `ContentProvider.openFile`, check if a file exists\n for the corresponding URI. If not, download and cache the image file. This\n code snippet uses [Glide](https://github.com/bumptech/glide).\n\n ### Kotlin\n\n override fun openFile(uri: Uri, mode: String): ParcelFileDescriptor? {\n val context = this.context ?: return null\n val file = File(context.cacheDir, uri.path)\n if (!file.exists()) {\n val remoteUri = Uri.Builder()\n .scheme(\"https\")\n .authority(\"my-image-site\")\n .appendPath(uri.path)\n .build()\n val cacheFile = Glide.with(context)\n .asFile()\n .load(remoteUri)\n .submit()\n .get(DOWNLOAD_TIMEOUT_SECONDS, TimeUnit.SECONDS)\n\n cacheFile.renameTo(file)\n file = cacheFile\n }\n return ParcelFileDescriptor.open(file, ParcelFileDescriptor.MODE_READ_ONLY)\n }\n\n ### Java\n\n @Nullable\n @Override\n public ParcelFileDescriptor openFile(@NonNull Uri uri, @NonNull String mode)\n throws FileNotFoundException {\n Context context = this.getContext();\n File file = new File(context.getCacheDir(), uri.getPath());\n if (!file.exists()) {\n Uri remoteUri = new Uri.Builder()\n .scheme(\"https\")\n .authority(\"my-image-site\")\n .appendPath(uri.getPath())\n .build();\n File cacheFile = Glide.with(context)\n .asFile()\n .load(remoteUri)\n .submit()\n .get(DOWNLOAD_TIMEOUT_SECONDS, TimeUnit.SECONDS);\n\n cacheFile.renameTo(file);\n file = cacheFile;\n }\n return ParcelFileDescriptor.open(file, ParcelFileDescriptor.MODE_READ_ONLY);\n }\n\n| **Note:** The content URI should be quickly constructed and sent to Android Auto and AAOS, as demonstrated in the previous example. This is true even when the file isn't downloaded. Android Auto and AAOS show a loading UI for the images when waiting for the content provider to respond. Consider optimizing your app to quickly fetch images and to minimize the time needed to load the UI. Consider preloading and caching images."]]
