Solve the problem of Chinese characters and spaces in file names during android download

If the connection is not processed for download, an error will be reported. To solve this problem, you only need to encode your url and then encode it with spaces.

// Encode the path and replace all spaces in the path. After encoding, the space becomes "+", and the space encoding is "% 20". Therefore, replace all "+" with "% ". 20.

Url = URLEncoder. encode (urlStr, "UTF-8"). replaceAll ("+", "% 20 ");

// The "/" in the encoded path also turns into something encoded, and all of them are replaced back. This is the complete path.

Url = url. replaceAll ("% 3A", ":"). replaceAll ("% 2F ","/");

The above method can solve the problem of Chinese characters and spaces when handling link downloads. If there are other special characters, you can use this method to solve the problem.
