1AHAT - Android Heap Analysis Tool
2
3Usage:
4 java -jar ahat.jar [OPTIONS] FILE
5 Launch an http server for viewing the given Android heap dump FILE.
6
7 OPTIONS:
8 -p <port>
9 Serve pages on the given port. Defaults to 7100.
10 --proguard-map FILE
11 Use the proguard map FILE to deobfuscate the heap dump.
12 --baseline FILE
13 Diff the heap dump against the given baseline heap dump FILE.
14 --baseline-proguard-map FILE
15 Use the proguard map FILE to deobfuscate the baseline heap dump.
16
17TODO:
18 * Add a user guide.
19 * Dim 'image' and 'zygote' heap sizes slightly? Why do we even show these?
20 * Let user re-sort sites objects info by clicking column headers.
21 * Let user re-sort "Objects" list.
22 * Show site context and heap and class filter in "Objects" view?
23 * Have a menu at the top of an object view with links to the sections?
24 * Include ahat version and hprof file in the menu at the top of the page?
25 * Heaped Table
26 - Make sortable by clicking on headers.
27 * For HeapTable with single heap shown, the heap name isn't centered?
28 * Consistently document functions.
29 * Show version number with --version.
30 * Show somewhere where to send bugs.
31 * Include a link to /objects in the overview and menu?
32 * Turn on LOCAL_JAVACFLAGS := -Xlint:unchecked -Werror
33
34 * [low priority] by site allocations won't line up if the stack has been
35 truncated. Is there any way to manually line them up in that case?
36
37 * [low priority] Have a switch to choose whether unreachable objects are
38 ignored or not? Is there any interest in what's unreachable, or is it only
39 reachable objects that people care about?
40
41Things to Test:
42 * That we can open a hprof without an 'app' heap and show a tabulation of
43 objects normally sorted by 'app' heap by default.
44 * Visit /objects without parameters and verify it doesn't throw an exception.
45 * Visit /objects with an invalid site, verify it doesn't throw an exception.
46 * That we can view the list of all objects in a reasonably short amount of
47 time.
48 * That we don't show the 'extra' column in the DominatedList if we are
49 showing all the instances.
50 * Instance.getDexCacheLocation
51
52Reported Issues:
53 * Request to be able to sort tables by size.
