Public Methods

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
