When the Activity (called DGraphActivity (xxxx-out proprietary namespace)
is set to a "standard" launchMode and I do a search of all the logCat
output I see two references to it
*03-29 19:21:04.357: I/ActivityManager(119): Force finishing activity
HistoryRecord{40698f18 com.xxxx.remote/.*
*DGraphActivity}
03-29 19:23:56.454: I/ActivityManager(119): Starting: Intent {
flg=0x4000000 cmp=com.xxxx.remote/.**DGraphActivity (has extras) } from pid
13727*
What was interesting about this is that my program has lots of Activities
and in all the other ones the "Starting: Intent" was followed immediately
by a "trying to launch..." the Activity in question. But DGraphActivity
had no "trying to launch", it just stops at "starting: intent" - that must
be some kind of clue but I don't know what.
*But*, when DGraphActivity's launchmode is set to singleInstance the logcat
shows this . . .
*03-31 18:49:12.224: I/ActivityManager(119): Starting: Intent {
flg=0x4000000 cmp=com.xxxx.remote/.DGraphActivity (has extras) } from pid
19024
03-31 18:49:12.298: W/ActivityManager(119): Trying to launch
com.xxxx.remote/.DGraphActivity
03-31 18:49:12.318: D/DGraphActivity(19024): created*
For my purposes I need it to be standard but I don't know how to interpret
this to glean why Android can start the Activity in singleInstance, but not
in standard mode
