错误打开跟踪文件android权限被拒绝

Question

I am getting a "error opening trace file: permission denied(13)" can somebody tell me what's that all about?

I've connected my phone instead of a virtual device...

And im kinda a noob in android still and I want to Log.d everything to see how it works but it doesn't quite work on my phone.

Answer 1

You are likely writing the log to the App's reserved disk space. This space is reserved for that specific app only. (Unless you're rooted- but that's a different topic altogether)

You are probably trying to read the log file from outside of your app, which is not allowed because this disk space is protected.

I would suggest trying to write the file to a shared memory location.
