Question

Starting Android 4.1 gettings android log requires ROOT permission, so now it’s impossible to
ask users to send log using apps like LogCollector, which just get android log and send it to email. Android log can be viewed using ddms app from Android SDK but it’s not good to ask users install Android SDK.

So, how to get android log from the users for Android 4.1 without rooting?

Answer 1

You can get your own app’s log without permission now. You can not read other apps’ logs at all, permission or not.

This is somewhat documented here. Just refer to Diane Hackborn’s response:

The change is that third party applications can no longer get the read
logs permission, however every app can read the logs containing only
the lines they have written, without needing any permission.

Keep in mind that access to the logs has never been part of the SDK,
and is still not part of the SDK. If you are relying on it then, even
after this change, you run the risk of breaking in the future. (And
that is partly why this got lost for documentation, it is not part of
the SDK, so there isn’t really a place to document it, in fact
documenting it would kind-of make it a part of the SDK which we don’t
want. :p)
