Log Streams & Merging

Android segregates its log output into several dedicated buffers. LogViewer automatically identifies each stream when opening multi-file log dumps and merges them into a single chronological timeline.

Recognized Log Streams

LogViewer automatically recognizes the standard Android log stream buffers:

  • main: General application and user-space logging.
  • system: Core framework, system services, and OS daemons.
  • events: High-level binary event logs (window transitions, screen power, process lifecycle).
  • radio: Cellular telephony, SIM card communications, and RIL events.
  • kernel: Low-level kernel driver messages (dmesg / /dev/kmsg).

Visual Stream Badges

When multiple log files with different streams are loaded together, each line in the log table displays a dedicated stream badge:

Stream Indication

This allows you to immediately tell whether a log line originated from the system server, the radio daemon, or an application process.

Toggling Streams in Filtered Output

When multiple streams are present, a Streams menu appears on the toolbar:

Selecting Streams

  • Check or uncheck individual streams to include or exclude them from your filtered output.
  • Stream toggles take effect instantly in memory without re-parsing files or re-running regex filters.
