pm grant <pkg> android.permission.READ_LOGS
pm grant org.jtb.alogcat.donate android.permission.READ_LOGS
Note that "pm" is a standard part of Android (I'm rooted but running stock JB on my N7) so you can just run it from the shell (adb shell) or from the command line via your favorite terminal emulator app like Android Terminal Emulator (https://play.google.com/store/apps/d...al.androidterm).
If you're interested in the details, there's a long discussion over in the Android Developers Google Group -- https://groups.google.com/forum/?fro...rs/6U4A5irWang
Note: I'm rooted so it may require root to work.
MOD: I've posted this in the Q&A section cuz it's the answer to a question but if it belongs elsewhere (Development? General?) then please move it.
