Public Methods
public static void startHierarchyTracing(String prefix, View view)
Starts tracing the view hierarchy of the specified view. The trace is identified by a prefix,
used to build the traces files names:
/tmp/view-hierarchy/PREFIX.traces and
/tmp/view-hierarchy/PREFIX.tree.
Only one view hierarchy can be traced at the same time. After calling this method, any
other invocation will result in a IllegalStateException unless
stopHierarchyTracing() is invoked before.
Calling this method creates the file /tmp/view-hierarchy/PREFIX.traces
containing all the traces (or method calls) relative to the specified view's hierarchy.
This method will return immediately if TRACE is false.
Parameters
| prefix | the traces files name prefix |
|---|---|
| view | the view whose hierarchy must be traced |
public static void stopHierarchyTracing()
Stops the current view hierarchy tracing. This method closes the file
/tmp/view-hierarchy/PREFIX.traces.
Calling this method creates the file /tmp/view-hierarchy/PREFIX.tree containing
the view hierarchy of the view supplied to startHierarchyTracing(String, View).
This method will return immediately if TRACE is false.
