Public Methods

public static AssetFileDescriptor getAssetFileDescriptor(ContentResolver contentResolver, Uri srcUri)

Gets the AssetFileDescriptor for a local file. This offers an alternative solution for opening content:// scheme files

Parameters

| contentResolver | the content resolver which will query for the source file | | srcUri | The source uri |

Returns
  • The AssetFileDescriptor for the file or null if it doesn't exist

public static String getRealPathFromUri(ContentResolver contentResolver, Uri srcUri)

Get the path of a file from the Uri.

Parameters

| contentResolver | the content resolver which will query for the source file | | srcUri | The source uri |

Returns
  • The Path for the file or null if doesn't exists

public static String getSchemeOrNull(Uri uri)

Parameters

| uri | uri to extract scheme from, possibly null |

Returns
  • null if uri is null, result of uri.getScheme() otherwise

public static Uri getUriForFile(File file)

Returns a URI for a given file using fromFile(File).

Parameters

| file | a file with a valid path |

Returns
  • the URI

public static Uri getUriForQualifiedResource(String packageName, int resourceId)

Returns a URI for the given resource ID in the given package. Use this method only if you need to specify a package name different to your application's main package.

Parameters

| packageName | a package name (e.g. com.facebook.myapp.plugin) | | resourceId | to resource ID to use |

Returns
  • the URI

public static Uri getUriForResourceId(int resourceId)

Return a URI for the given resource ID. The returned URI consists of a LOCAL_RESOURCE_SCHEME scheme and the resource ID as path.

Parameters

| resourceId | the resource ID to use |

Returns
  • the URI

public static boolean isDataUri(Uri uri)

Check if the uri is a data uri

public static boolean isLocalAssetUri(Uri uri)

Check if uri represents local asset

Parameters

| uri | uri to check |

Returns
  • true if uri's scheme is equal to "asset"

public static boolean isLocalCameraUri(Uri uri)

Checks if the given URI is for a photo from the device's local media store.

Parameters

| uri | the URI to check |

Returns
  • true if the URI points to a media store photo

public static boolean isLocalContactUri(Uri uri)

Checks if the given URI is a general Contact URI, and not a specific display photo.

Parameters

| uri | the URI to check |

Returns
  • true if the uri is a Contact URI, and is not already specifying a display photo.

public static boolean isLocalContentUri(Uri uri)

Check if uri represents local content

Parameters

| uri | uri to check |

Returns
  • true if uri's scheme is equal to "content"

public static boolean isLocalFileUri(Uri uri)

Check if uri represents local file

Parameters

| uri | uri to check |

Returns
  • true if uri's scheme is equal to "file"

public static boolean isLocalResourceUri(Uri uri)

Check if uri represents local resource

Parameters

| uri | uri to check |

Returns
  • true if uri's scheme is equal to LOCAL_RESOURCE_SCHEME

public static boolean isNetworkUri(Uri uri)

Check if uri represents network resource

Parameters

| uri | uri to check |

Returns
  • true if uri's scheme is equal to "http" or "https"

public static boolean isQualifiedResourceUri(Uri uri)

Check if uri represents fully qualified resource URI.

Parameters

| uri | uri to check |

Returns
  • true if uri's scheme is equal to QUALIFIED_RESOURCE_SCHEME

public static Uri parseUriOrNull(String uriAsString)

A wrapper around parse(String) that returns null if the input is null.

Parameters

| uriAsString | the uri as a string |

Returns
  • the parsed Uri or null if the input was null

public static URL uriToUrl(Uri uri)

Convert android.net.Uri to java.net.URL as necessary for some networking APIs.
