The Android Log View window is named Android Log and is showed by clicking the Tegra > Windows > Android Log (logcat) menu item.
The figure below shows the Log Window view, in the state that occurs when the filters panel has been closed.
For reference, the controls numbered above include:
When resizing the window horizontally, the width of the search text box changes accordingly. If the window width is not enough to contain all of the toolbar controls, the search text box can be collapsed, and the toolbar controls on the far right can be hidden.
Below the toolbar is the main log list view area. The List View is capable of selecting multiple lines using standard
Shift + click and
Ctrl + click actions.
Shift + click will select all the lines from the first selected line to the clicked one.
Ctrl + click will toggle the selected state of the clicked line.
Some of the log lines from the Android logcat command may not be recognized by the Log View. These lines are marked by the Unrecognized level, and have dummy values in each field, with the exception of Text, which contains the full log message text.
Each log line has a color that is calculated from the log message's level. The colors are:
The List View has a context menu with the following menu items:
Double-clicking the List View column’s right border will auto-resize that column to the size of the longest currently visible value in that column.
Searching is available via the search text box, and has the following capabilities:
Notes on searching:
Android Log View can be filtered using two different features.
The Message Importance Level drop-down box has the following values:
Selecting any of these levels will show only the log lines which has a level that is equal or more severe (important) than the selected level. For example, selecting
Info will filter out all the
Debug log messages. In this mechanism, any unrecognized log lines are treated as
The persistent filters panel can be opened by pressing the Show Filters Panel button. The default Android Log window view with the filters panel open is displayed below.
The vertical bar between the filters panel and the main area can be adjusted to resize the filters panel.
+ button will open an Add Filter dialog, as shown below.
The Name field will be shown in the filters window. The Name field is not unique and can be empty. Filter by Tag, Filter by Text, and Filter by PID behaves the same as the Searching by tag, text, and pid behaviors. The Filter by Log Level behavior is the same as the Message Importance Level filter.
Filter fields are combined using logical
AND. For example,
Filter by PID = 4129 and
Filter by Tag = System.err will show only the log lines whose pid is
4129 and tag is
The filters panel with two added filters is displayed below.
Each filter has a number in parentheses associated to it, which indicates how many log lines satisfy the filter’s conditions. That number changes dynamically as log lines are added or removed. Turning the filter on and off can be done via clicking anywhere inside the filter’s listbox item (except for the rightmost two-button area). Enabled filters are designated by marked checkboxes. If the filter name is too long to fit into the listbox, then it is trimmed and ellipsis (
…) is added to the name.
It is possible to use multiple persistent filters, by checking several listbox items at once. The filtered result is calculated as filtered log lines of each filter combined by logical
OR. Note that the combined log lines' count is not necessarily equal to the sum of the filters’ reported filtered log lines count. This is because one log line may satisfy different filters and therefore is included in several filters’ results at once.
When the mouse cursor hovers over the listbox item, two buttons are shown. These buttons can be used for either deleting or editing the filter.
Several aspects of the view are preserved between the Visual Studio runs, such as:
However, the search box text is not persisted.
