Could not launch mailto:support@k8sllc.com?subject=请写以上这个线

Answer 1

You should encode your url:

String url = Uri.encodeComponent('mailto:support@test.com?subject=请写以上这个线');

so it looks like this:

mailto%3Asupport%40test.com%3Fsubject%3D%E8%AF%B7%E5%86%99%E4%BB%A5%E4%B8%8A%E8%BF%99%E4%B8%AA%E7%BA%BF
