You might try asking the package manager if the intent you're sending
will have any receivers, also..

No.

But you should see something in the logcat that shows an intent was
fired.  Do you not see that?  The system does not "drop intents
randomly".  Can you point out concrete cases where it has without
sufficient error messages, because those would be bugs..

There's not logged output from the Android internals that give an
account of why your intent is "dropped" but I am more confused as to
why this would be happening in the first place.  In the past, whenever
I've heard this happening, it's because there's always been something
like a misspelling of package name, or something's been signed
incorrectly..

Why aren't there tutorials on YouTube regarding any subject not represented 
on YouTube?

It's a silly question.

I think Spooky has the best answer, which I'll paraphrase as "because no 
one has made one 
and uploaded it."

Or maybe he's right and your search wasn't correct.

Or maybe the goons at Censors 'R' Us have had them all deleted.

Or maybe they all violated copyright and were taken down under the DMCA.

Or maybe all the video tutorials are proprietary and you have to pay to see 
them.

Or maybe there's a filter preventing you, personally and specifically, from 
finding them 
while the rest of us enjoy them with white wine and paté de fois gras.

Perhaps nobody's made one?  Or you just didn't find the right search
(I've run into this plenty of times, myself).  If you can't find one,
maybe you should pay someone to do one (seriously).  If not, I'm sure
you'll find plenty of books on the subject.

*My bad* -  it turned out it did have a filter on.  (thanks for saying you 
never saw that - it made me look twice!)   With it off  I do get 2 logcat 
messages about this activity  (I've "'d out some proprietary 
content).   I'm not sure what these mean . . .

flg=0x400 cmp=com..remote/.DGraphActivity (has extras) } from pid

What was interesting about this is, as I mentioned, 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"!   So that seems to be a clue but 
I don't know of what.

No I haven't -  thought that just places it outside the others on the

Also, change the catching of your try - catch block, so that you see more 
of the exception being thrown when the activity fails to start:

   Log.*e*("Commands", "failed to start DGraphActivity"*, e*);

This would allow you to see more info of what may go wrong.

I've never seen this. If it fails to start, i get a logcat message and an

Have you tried to set the Intent.FLAG_ACTIVITY_NEW_TASK flag when starting

I works for me as well, that's why I wrote "technically".  It's just not 
documented to work, see:
http://developer.android.com/guide/topics/manifest/activity-element.html#nm

and as you were having trouble I though it might help.

I only see things in LogCat about  DGraphActivity when it *does* start 
(ie., when its launchMode is "singleInstance").Are you saying there 
should be a message that it failed to start (or failed to be created)?   I 
run Logcat with no filters and in verbose mode so I think I'm seeing 
everything there is.

The manifest is exactly as it's shown - the *only* difference between the 
successful case and the failing case is the launchMode, so if there was a 
typo it would have to be unique to that line.Furthermore it only works 
for singleInstance, it fails for standard, singleTop and singleTask, so if 
there was a typo it would have to be in all three of those but not in the 
singleInstance case.

When an activity fails to start all I see in LogCat is .. *nothing* related 
to that Activity.   If the Activity is created or started (or paused, etc) *
then* I see it in Logcat.   Are you saying that I should see a message 
saying that the Activity failed to start or be created?   I run LogCat in 
verbose mode with no filters on.

In that particular example the returning Activity was standard but the 
Activity *invoking* it was singleInstance.   I knew the returning Activity 
had to be standard but I only found out that the caller couldn't be 
singleInstance by time-consuming trial-and-error.I've never seen it

worked.  Which illustrates my question:   which is whether there's a

I'm currently trying to debug a case where I can ONLY start an activity if 
it's singleInstance.   I don't know why and lots of people on StackOverflow 
have made many guesses and suggestions, none of which (as of this writing) 
have worked.Because we're all fumbling in the dark since we don't know 
what Android is doing behind the scenes.   I want to know if there's a way 
to find out.

Look at your logcat and see why your activity can't be started. Could be as

Look at your logcat. It tells you when an activity hasn't started. 
For the onActivityResult getting called instantly: Your returning activity 
was probably started with a singleTask or singleInstance. This means that 
onActivityResult was called immediately after your activity was started 
(and not upon its return). Use default/standard instead.

[android-developers] refresh fragment on swipe?

[xrd]

I'm trying to get a fragment working such that when the fragment is brought 
into view it refreshes the content in the view. 

I thought that I could implement OnPageChangeListener and 
override onPageSelected but my breakpoint is never hit. Is there a better 
way? Or, perhaps this means I am doing things wrong somewhere in my code?

I've also tried using onResume(), but this does not get called each time 
the fragment is displayed, which is what I need.

Any suggestions?

response.putExtra("exit_flag", "y");
setResult(RESULT_OK, response);
finish();

I was expecting onActivityResult() to get called in the original
app, but it never does.  Is there something different about launching
other apps rather than just new activities in the same app?

Thanks!

Toby

[android-developers] Debugging the Activity life-cycle?

[plnelson]

Over many projects I've run into various problems with Activities doing 
mysterious things.   I've had them not start; I've had onActivityResult not 
get called when I'm trying to send parameters back from an Activity; I've 
had onActivityResult get called *instantly* before the other Activity even 
got created.Googling the web I see that lots of people have these 
problems and often these either stump people on StackOverflow or result in 
random "superstitious" fixes with no obvious basis - even if they sometimes 
seem to work.
 
So* My Question*:  is there any *systematic* way to debug Activity 
life-cycle problems - are there log files, traces, dumps, or anything that 
programmers can use to figure out why something is happening.If I call 
"startActivity" and the activity is never created or started, is there 
anyplace Android tells us why?   If onActivityResult is called prematurely 
(i.e., before the Activity that's supposed to return the result even 
exists) how can we find out why it was called? Are there any hints of 
tricks to interpreting the call stack that can shed light on that?

Thanks in advance for any tips or tricks.

[android-developers] Getting a message from another app launched with an Intent

[Tobiah]

I'm launching another app from my app like this:

Intent LaunchIntent = 
getPackageManager().getLaunchIntentForPackage("com.other.appname");
startActivityForResult(LaunchIntent, EXPOSMART_MESSAGE);

Then I set a result from the launched app:

Intent response = new Intent();
response.putExtra("exit_flag", "y");
setResult(RESULT_OK, response);
finish();

I was expecting onActivityResult() to get called in the original
app, but it never does.  Is there something different about launching
other apps rather than just new activities in the same app?

Thanks!

[android-developers] Activity won't start when launchmode is standard

[plnelson]

This question has (so far)  stumped them on Stack Overflow. . . . 

I'm trying to launch an Activity which launches *perfectly fine* when its 
launchMode is set to *singleInstance*. When I change it to *standard*nothing 
happens; it never gets to onCreate (or onStart or onResume, or 
anyplace in the target Activity - I've overridden all the lifycycle events 
and set breakpoints)

if (DGraphActivity.bitmap != null) {
Intent intent = new Intent(ctx, DGraphActivity.class);
intent.putExtra("Buttons", sButtonParam);
try {
ctx.startActivity(intent);
}
catch (Exception e)  {
Log.d("Commands", "failed to start DGraphActivity");   
}}   

in the manifest . . . 



I need the DGraphActivity launchMode to be *standard* because it will be 
launching another activity and using onActivityResult to collect the 
response and onActivityResult doesn't work with activites launched in 
singleInstance launchMode. 

I have lots of other Activities with *standard* launchMode that launch 
perfectly well, I can't figure out what's different about this one. Thanks 
in advance!

[android-developers] Re: Deadlock running app on Nexus 10, Android 4.2.2

[bergstr]

ok, I have changed the code such that the frequent calls into native code 
(in method validateKey) don't happen any longer. They were unneeded anyway, 
as the internal cleanup thread can safely assume that the keys are valid. 
With this change, I can no longer reproduce this issue.

However, I am still left with the impression that Android may at any point 
suspend background threads in favor of the UI thread regardless of their 
state and whether they hold locks. If this is true, it imposes very hard 
requirements on the programmer to avoid cases where lock contention between 
the UI thread and a background thread can lead to a deadlock, as in my 
case. At the very least, I would expect this to be documented somewhere, 
preferably in a prominent place..

[android-developers] GroundOverlay with rotation in MapView

[Brofalad]

Hi,
 
I have a overlay image with the following cooridinates. 
 

  56.56509012808
  56.5455371985222
  13.249250664387
  13.2017977722382
  0.477325392961741

 
It is no problem to create the overlay without the rotation. But is it 
possible to rotate the image, or can I only use images with rotation = 0.
/Brofalad
