Android Question Target SDK version is set to 26 ،, it comes out and doesn't work on Huawei phones

[zavaree]

Hi Earl, I have an application where I download a pdf file and save it to a folder on my phone. When the Target SDK version is set to 26 ،, it comes out and doesn't work on Huawei phones, what is the cause and what is the solution?

Hi Earl,

You shouldn't limit your questions to a single member.

what is the cause and what is the solution?

We can only guess as you haven't provided any information. You should explain what "doesn't work" means, post the relevant code and the logs.

It just can't find a pdf file. Check if path/filename is correct (case sensitive!)
