[android-developers] Re: File not found exception, while listed in manifest.xml file
you're not defining the activity correctly in the manifest...
the activity name field needs a fully classified path to the class or
should start with a period to fill in the package declared in the manifest.

Re: [android-developers] Re: OutofMemory Excepton error in android
Actually even 5K can crash his app... it all depends on what he did before
the allocation.
Android has a nasty bug of claiming you dont have enough memory even if
your heap has more than enough free space if it grew close to its maximum
value previously (and dont't forget fragmentation as well, 10MB of free
heap doesn't mean you can allocate 10MB).
Basically i found that if i get a OOM exception when the allocated size
isn't something enormous, it's usually because is misbehaved earlier :)
So my suggestion to Karunakar (assuming he can't do random reads on the
file and the file isn't really big) is to profile his app and see if he
needs to do some fixing up before he gets to the point of reading the file.
Other than that, he can always try the big heap flag or just dump
everything to native heap.

In general, you can't allocate that much space on Android. To combat
this you need to be able to do lazy I/O.
But ... are you trying to read in a dictionary (using apertium?). I'd
guess this is a few megabytes at least right? Having a megabyte or
two on the heap won't necessarily crash your app, but having more than
that certainly can! (This of course, depends on the device..)

Re: [android-developers] Re: File not found exception, while listed in manifest.xml file
just to be clear:
in the manifest the manifest tag needs to say
manifest ...package=com.playcez.start ...
then your source directory needs to be
../src/playcez/Start.java
And then the activity can have the name as .Start
P.S - You should probably add another level to the package declaration...
you'd usually want all your apps to share the same package ... so assuming
playcez is your dev/company name you should add another level for the app
itself... so if you'll have another app, you can still use the com.playcez
package.

manifest xmlns:android=http://schemas.android.com/apk/res/android;
package=com.playcez
android:versionCode=1
android:versionName=1.0
Start is a FragmentActivity inside this package..

you'd usually want all your apps to share the same package ... so assuming

Re: [android-developers] Re: File not found exception, while listed in manifest.xml file
is the file structure is correct (app/src/com/playcez/Start.java)
(which i got wrong before as well lol.. i always forget the com)
Also, your activity code doesn't have the package declared in it... it
should say package com.playcez; at the top

yes, correct Piren,
1. Activity class package com.playcez; is mentioned.
2. and Start.java is in correct package name
Basically this project is working in different box(laptop), and i'm trying
to import this project, since 2-3 i'm getting error and not getting any
clue. :(

try the various suggestions offered here:

Also since you said you imported the project... i'd give it a second go.
delete it all, copy the entire app folder again, go into eclipse an import
existing project, uninstall for the phone and give it a go.

Re: [android-developers] Re: OutofMemory Excepton error in android
Thanks to everyone.
Am using code which are written by the apertium people. Am just integrating
apertium program to my programs. I have increase heap size in emulator some
time i did not get any result after that i reduced heap size to middle
level at this i got same OOM error. What should i do if i suppose to use
apertium in my android application.
Let we assume that if it works fine when we increase heap size in
emulator,later i will install that app in some android tablet or phone.
how can we increase the heap size in such devices.
Why am have to use Apertium ?
Am developing applications which are related to sanskrit languages.Here we
can find what exactly am doing .http://sanskrit.uohyd.ac.in/scl/ (web

Actually even 5K can crash his app... it all depends on what he did before

Android has a nasty bug of claiming you dont have enough memory even if
your heap has more than enough free space if it grew close to its maximum
value previously (and dont't forget fragmentation as well, 10MB of free
heap doesn't mean you can allocate 10MB).
Basically i found that if i get a OOM exception when the allocated size
isn't something enormous, it's usually because is misbehaved earlier :)
So my suggestion to Karunakar (assuming he can't do random reads on the
file and the file isn't really big) is to profile his app and see if he
needs to do some fixing up before he gets to the point of reading the file.
Other than that, he can always try the big heap flag or just dump
everything to native heap.

In general, you can't allocate that much space on Android. To combat
this you need to be able to do lazy I/O.
But ... are you trying to read in a dictionary (using apertium?). I'd
guess this is a few megabytes at least right? Having a megabyte or
two on the heap won't necessarily crash your app, but having more than
that certainly can! (This of course, depends on the device..)

Re: [android-developers] Re: OutofMemory Excepton error in android
it depends on how much heap you defined for the emulator. if it didnt crash
with 24mb, you're pretty much safe for 99% of the devices out there (i
think even 48mb will cover most devices out there)
Otherwise, if you can't figure out a way to reduce your memory allocations,
just set the largeHeap flag

Thanks to everyone.
Am using code which are written by the apertium people. Am just
integrating apertium program to my programs. I have increase heap size in
emulator some time i did not get any result after that i reduced heap size
to middle level at this i got same OOM error. What should i do if i suppose
to use apertium in my android application.
Let we assume that if it works fine when we increase heap size in
emulator,later i will install that app in some android tablet or phone.
how can we increase the heap size in such devices.
Why am have to use Apertium ?
Am developing applications which are related to sanskrit languages.Here we

Android has a nasty bug of claiming you dont have enough memory even if
your heap has more than enough free space if it grew close to its maximum
value previously (and dont't forget fragmentation as well, 10MB of free
heap doesn't mean you can allocate 10MB).
Basically i found that if i get a OOM exception when the allocated size
isn't something enormous, it's usually because is misbehaved earlier :)
So my suggestion to Karunakar (assuming he can't do random reads on the
file and the file isn't really big) is to profile his app and see if he
needs to do some fixing up before he gets to the point of reading the file.
Other than that, he can always try the big heap flag or just dump
everything to native heap.

In general, you can't allocate that much space on Android. To combat
this you need to be able to do lazy I/O.
But ... are you trying to read in a dictionary (using apertium?). I'd
guess this is a few megabytes at least right? Having a megabyte or
two on the heap won't necessarily crash your app, but having more than
that certainly can! (This of course, depends on the device..)

[android-developers] RESTful webservice with auth for mobile application
I have developed many stateless RESTful webservices for a mobile
application in Java and they are working very well.
*For example:*
- h t t p://.../api/coupon
- h t t p://.../api/coupon/{id}
- ...
Now, I have to extend these services because I have to send different data
back to the mobile for every user. So I need to know on the server side
which user try to get or set information. And I have to prevent the serve
of unauthorized users.
*There are two different way how user can login into the mobile
application: *
1. log in with facebook account
2. log in with an application account
I need to develop two login and a logout services because the users who use
the mobile application have to login into the application.
I read lots of article about auth and RESTful and OAuth.
I think I have to develop two login services with two imput parameters:
username and password.
*For example:*
- localLogin(String username, String password) - token
- facebookLogin(String username, String password) - token
These logon services have to generate a same token and send it back to the
mobile application in the http header. And after the login process the
mobile client has a token. And the client has to send this token to the
server when it makes a RESTful server call.
What do you think? Is my idea good?
If it is, could you help me how can I start to develop this in Java?
If it is not, could you tell me the good way?
Thank you.

Re: [android-developers] Re: OutofMemory Excepton error in android
There's quite a big discussion of this bug somewhere hidden in the bug reports, i've come across the issue myself and found its rather easy to replicate. basically just write a loop that allocate a whole boat load of memory. run it till it poops on you then limit it to do a bit less iterations. that way the heap size will grow to very close to the top limit. then drop all the objects to free up the heap (you can even force a GC). wait a short while to see the heap is truely cleared, then allocate a big object (big enough to pass the difference between Total and Max heap size but smaller than the free heap space). see the world come down and say WTF? basically they check memory allocation against the total heap size instead of the free heap size. Maybe because its easier to compare an int value than to assume there's space, than fail to find sufficient space due to fragmentation.. it could be they did it on purpose just to speed up memory allocations. (since they dont support defragmentation either... which is also why they dont support heap size reductions) On Thursday, March 14, 2013 4:56:37 PM UTC+2, Kristopher Micinski wrote: Is that really the case?

Re: [android-developers] Re: OutofMemory Excepton error in android
What you're saying is true under some conditions (as i stated, i'm aware of fragmentation)... but i think it will take quite a horrible alignment of stars for it to fail because of the reason you stated... in my tests i wasn't allocating huge chunks, barely 100K or so... i truly doubt every single one of my tests didn't have 100K of contiguous space out of 15+ MB of free space left after the GC. The test you describe doesn't prove it 100% either though... if Dalvik is a serious asshole it can decide to put 1 byte of data inside the middle of each of the freed areas just after the GC (for whatever reason) , that would break the test as well... the only way to 100% prove it is to see the error in the source code. Even mapping the memory and seeing it has enough free space wouldn't help since there might be another (unrelated) issue that causes Dalvik to miss contiguous spaces on some occasions. Either way, i had it happen to me and many other users who describes the exact same behavior, i doubt it isnt a real issue :) (though anyway, the way to solve it is the same either case - never allocate so much memory to begin with) On Thursday, March 14, 2013 6:38:47 PM UTC+2, Mark Murphy (a Commons Guy) wrote: On Thu, Mar 14, 2013 at 12:28 PM, Piren gpi...@gmail.com javascript: wrote: There's quite a big discussion of this bug somewhere hidden in the bug reports, i've come across the issue myself and found its rather easy to replicate. basically just write a loop that allocate a whole boat load of memory. run it till it poops on you then limit it to do a bit less iterations. that way the heap size will grow to very close to the top limit. then drop all the objects to free up the heap (you can even force a GC). wait a short while to see the heap is truely cleared, then allocate a big object (big enough to pass the difference between Total and Max heap size but smaller than the free heap space). see the world come down and say WTF? basically they check memory allocation against the total heap size instead of the free heap size.

Android has a nasty bug of claiming you dont have enough memory even if
your heap has more than enough free space if it grew close to its maximum
value previously (and dont't forget fragmentation as well, 10MB of free
heap doesn't mean you can allocate 10MB).
Basically i found that if i get a OOM exception when the allocated size
isn't something enormous, it's usually because is misbehaved earlier :)
So my suggestion to Karunakar (assuming he can't do random reads on the
file and the file isn't really big) is to profile his app and see if he
needs to do some fixing up before he gets to the point of reading the file.
Other than that, he can always try the big heap flag or just dump
everything to native heap.

In general, you can't allocate that much space on Android. To combat
this you need to be able to do lazy I/O.
But ... are you trying to read in a dictionary (using apertium?). I'd
guess this is a few megabytes at least right? Having a megabyte or
two on the heap won't necessarily crash your app, but having more than
that certainly can! (This of course, depends on the device..)

How about this test: - Figure out the biggest allowable heap for the device - Start a fresh app that tries to allocate one big ass object that will expand the heap to it's maximum size within a minimal distance of it - GC that object and make sure the Free Heap has that big ass object space back - Allocate an object the size of that minimal distance + some extra space The higher the ratio between the big ass object and the OOM object, the higher the chance this issue is real :) (I.e - Very unlikely that after GC's a 20MB object, you would not be able to allocate a 5K due to fragmentation) On Thursday, March 14, 2013 6:38:47 PM UTC+2, Mark Murphy (a Commons Guy) wrote: On Thu, Mar 14, 2013 at 12:28 PM, Piren gpi...@gmail.com javascript: wrote: There's quite a big discussion of this bug somewhere hidden in the bug reports, i've come across the issue myself and found its rather easy to replicate. basically just write a loop that allocate a whole boat load of memory. run it till it poops on you then limit it to do a bit less iterations. that way the heap size will grow to very close to the top limit. then drop all the objects to free up the heap (you can even force a GC). wait a short while to see the heap is truely cleared, then allocate a big object (big enough to pass the difference between Total and Max heap size but smaller than the free heap space). see the world come down and say WTF? basically they check memory allocation against the total heap size instead of the free heap size.

[android-developers] Nested dialogs
I have a search results screen with a complex set of filters that I'm in the process of building out. I'm giving the user a filter icon in the ActionBar that will pop up a dialog with filter options. I feel that this is pretty standard. I don't want the user to feel like they're navigating away when modifying their filters, so I'm not showing a full screen filter activity. Now it's time to implement a few multi-select fields. So, on my filter which is already a dialog on top of the search results activity, I'm going to pop up another dialog with the multi-select options. This doesn't feel great, and I've seen others express that nested dialogs are a bad user experience and I mostly agree with this sentiment. This has to be a common case though, so what is typically the way around this?

What is the problem with singleton? It works very well. I use it to hold global state, for example, translations.

I can control everything there - reinitialize if destroyed, etc. There's also a very popular image loading library, which works very well for me, which also uses the singleton pattern.

Re: [android-developers] Re: Can this variable become null?
I guess the bigger problem that in Android static data members cannot be statically checked to be alive. By this I mean: you should try to get as much static checking as possible, and if you're using statics you don't have any ability to properly check this. Moreover, in Android it's a fact of life that your app will die and restart. You can really only use statics for caching type purposes, but working with them in a safe way quickly becomes extremely complicated. Instead of doing this, you can typically replace singletons with some Android specific utility (a Service or ContentProvider, say..) that allows you to implement the singleton type pattern. This really *is* a pretty frequent problem when people get UI elements stuck into static variables and then users rotate the screen :-) Kris On Thu, Mar 14, 2013 at 7:11 PM, Mark Murphy mmur...@commonsware.com wrote: On Thu, Mar 14, 2013 at 7:00 PM, user123 ivanschu...@gmail.com wrote: What is the problem with singleton? http://stackoverflow.com/questions/7026507/why-are-static-variables-considered-evil http://stackoverflow.com/questions/137975/what-is-so-bad-about-singletons And, since they don't seem to emphasize the point quite enough for my taste: static data members are, by definition, memory leaks.

In order to answer your question, we need to see the code where you create
and set mmInstream, too. For all we know, you might have forgotten to
connect it to any stream,

here i am trying to send a file over bluetooth but its not sending any
data.
here the main problem is that its not sending or receiving any data over
the two devices but they are connected to each other.
on configuring the bluetooth chat example.
Sending code:
File myFile = new File(message.toURI());
Are you quite certain 'message' translates properly to a URI that the
'File' constructor can use?
Are you certain that the abstract pathname represented by the 'File'
instance is accessible?
Double nosofpackets = Math.ceil(((int) myFile.length() )/4096);
'Math.ceil()' makes no sense with integer expressions. It will only return
the argument's value.
Are you quite certain that the length of the file will fit in an 'int'?
Why does 'nosofpackets' (a non-compliant name) have to be 'Double' rather
than 'double'?
System.out.println(nosofpackets);
BufferedInputStream bis= new BufferedInputStream(new
FileInputStream(myFile));
byte[] send = new byte[4096];
for(double i=0; inosofpackets; i++)
'int' would be a better type for a loop index. It's actually pretty strange
to think about what
a 'double' is doing here.
{
send = null ;
So why do you null out this variable and forget and eventually de-allocate
the array?
a=bis.read(send, 0,send.length);
NPE!
You can't get the length of 'null'.
You did not tell us you were getting exceptions. How come?
What is 'a'?
Log.d(BluetoothChat, data packet + i);
if(a==-1)
{
break;
}
mChatService.write(send);
}
Receiving code :
while((bytes = mmInStream.read(buffer))0)
What are these variables?
{
Log.d(TAG, data is there for writing);
bos.write(buffer);
}
Incomplete question, cannot be answered completely.

Re: [android-developers] Re: Can this variable become null?
Kristopher Micinski wrote: I guess the bigger problem that in Android static data members cannot be statically checked to be alive. By this I mean: you should try to get as much static checking as possible, and if you're using statics you don't have any ability to properly check this. Moreover, in Android it's a fact of life that your app will die and restart. You can really only use statics for caching type purposes, but working with them in a safe way quickly becomes extremely complicated. Instead of doing this, you can typically replace singletons with some Android specific utility (a Service or ContentProvider, say..) that allows you to implement the singleton type pattern. This really *is* a pretty frequent problem when people get UI elements stuck into static variables and then users rotate the screen :-) Kris On Thu, Mar 14, 2013 at 7:11 PM, Mark Murphy mmu...@commonsware.comjavascript: wrote: On Thu, Mar 14, 2013 at 7:00 PM, user123 ivans...@gmail.comjavascript: wrote: What is the problem with singleton? http://stackoverflow.com/questions/7026507/why-are-static-variables-considered-evil http://stackoverflow.com/questions/137975/what-is-so-bad-about-singletons And, since they don't seem to emphasize the point quite enough for my taste: static data members are, by definition, memory leaks. How *bad* of a memory leak they are depends on what they are and how they are used. Like many programming techniques, singletons can be used as a scalpel or a sledgehammer. The general advice against singletons is because most people reading that advice are inexperienced and are likely to do damage with either a scalpel or a sledgehammer. On the whole, AFAICT, tolerance for singletons decreases with increased production Java development experience, based on the conversations that I have had on the topic over the past few years. I've been using Java professionally for fourteen years. The biggest problem I have with singletons is that everyone for some god-awful reason insists on lazily instantiating them. Why? Lazy instantiation is lazy. What's wrong with non-lazy instantiation? Then you can use a 'final' reference to the singleton instance that exists without effort or overhead. -- Lew -- -- You received this message because you are subscribed to the Google Groups Android Developers group.
