Subject: [PATCH] DO NOT MERGE Ignore - Sanitized uri scheme by removing scheme
|
|
delimiter
|
|
|
|
Initially considered removing unsupported characters as per IANA guidelines, but this could break applications that use custom schemes with asterisks. Instead, opted to remove only the "://" to minimize disruption
|
|
|
|
Bug: 261721900
|
|
Test: atest FrameworksCoreTests:android.net.UriTest
|
|
|
|
No-Typo-Check: The unit test is specifically written to test few cases, string "http://https://" is not a typo
|
|
(cherry picked from https://googleplex-android-review.googlesource.com/q/commit:1fd0421801c391dd619cafeeea8d379a9029074a)
