Current Behavior

Our app is working with video files and playing/fetching them mainly through range requests. Sometimes it also needs to access larger video files that have a size of 2 GB or more through range request to stream media within the WebView. When accessing a large media file (> 2.14 GB), the local file server fails due to an integer overflow when handling the local request. This is caused by the fact that the range headers are parsed into an Integer. The integer can only represent numbers up to 2147483647 Bytes (2,14... GB) so parsing the Integer from the range request fails.

Expected Behavior

The range request should also work for files larger than 2.14 GB.

Code Reproduction

Other Technical Details

The issue is caused within the handleLocalRequest function in android/capacitor/src/main/java/com/getcapacitor/WebViewLocalServer.java:202.

int totalRange = responseStream.available(); // totalRange integer overflow
String rangeString = request.getRequestHeaders().get("Range");
String[] parts = rangeString.split("=");
String[] streamParts = parts[1].split("-");
String fromRange = streamParts[0];
int range = totalRange - 1; // range integer overflow
if (streamParts.length > 1) {
    range = Integer.parseInt(streamParts[1]);
}
