Personally, as a user I welcome this change. My concern was that this wasn't mentioned in changes description. And what's more important there is no way to enable READ_LOGS during development/testing process. It's good there are (tentative?) plans to introduce a way to enable such permissions for developers in later releases. It would've been great to have both these changes at the same time. But we have what we have.
By the way, thanks for the power + volume down + volume up trick. Didn't know it existed. This somewhat mitigates the issue in some cases. /Ievgenii Nazaruk On Thursday, July 12, 2012 8:15:33 PM UTC+3, Dianne Hackborn wrote: > > Applications accessing the system logs has been a long-standing issue. > There is various code in the system that tries to trim personal and other > dangerous information out when it prints to the log, but this often misses > things, and just makes the system using the logs much more complicated and > risky. > > The logs are also a target for malware, since it can look at what is being > printed there to infer a lot about what is going on in the device. > > Plus, as I said, access to the logs has never been any part of the SDK, > and this was very deliberate, because it is not a facility we want > applications to use or feel like we can maintain for applications as the > platform evolves. > > If you want the user to give you debugging information, you can have them > generate a bug report with power + volume down + volume up which includes > the logs and lots of other data, and automatically brings up their e-mail > app to sent it all (plus a screenshot).
