Re: [android-developers] How to stop terminate the Android application when using the native code
I know, i can disable it, so it will work, but i'd like to let the app can run many times again. So i disable the exit(), but when call the second times, it generates errors. Could you help?

Re: [android-developers] NFC Application

I´m a german dev-beginner and i can tell you, our taxsystem is as complex as hell... I think you have a german giro-account right? So the way i would go is to contact the local depatment of taxes where your bank is located. They might help you much better than any dev because the whole thing depends on the location of your business... If you have your business in germany you have to pay full taxes at all... if you are located in EU you might have to pay Mehrwertsteuer in germany but your countrydepending taxes (to YOUR country) for the business.. If you locate the business in not EU countrys you have to pay duty and so on and so on... so if you like to tell me which institute you use i´m able to tell you witch departemnt you have to call.

First, it is rather unlikely that the OS will kill the process right after this call returns. Second, if you are trying to do anything that takes a while in onSaveInstanceState(), you're doing it wrong. You should be triggering that work in other places (e.g., onPause(), on an explicit action bar item click), and using a background thread in those places as well. For example, onSaveInstanceState() has nothing to do with a persistent data model (e.g., database).

Re: [android-developers] Re: static vs non-static inner classes
Note that there is now an Android Lint check for non-static inner classes
that extend Handler. See HandlerLeak:
http://tools.android.com/tips/lint-checks
I've implemented a Handler.Callback wrapper that wraps the Callback
(usually an inner class) in a WeakReference, and I construct the Handler
instance using the wrapped Callback. This way, the code that used to exist
in the leaky Handler inner class now exists in the Callback implementation.
This seems to have the least impact on the source code, while still
removing the potential leak.

I wrote that debugging code because of a couple of memory leaks I

reference to the Handler which, when it's inner and non-static, has a
reference to the outer this (an Activity for instance.) If the Message
lives in the queue for a long time, which happens fairly easily when
posting a delayed message for instance, you keep a reference to the
Activity and leak all the views and resources. It gets even worse
when you obtain a Message and don't post it right away but keep it
somewhere (for instance in a static structure) for later use.
If you want to use the equivalent of an inner-class but not risk a
leak, here's a simple pattern:
class OuterClass {
class InnerClass {
private final WeakReferenceOuterClass mTarget;
InnerClass(OuterClass target) {
mTarget = new WeakReferenceOuterClass(target);
}
void doSomething() {
OuterClass target = mTarget.get();
if (target != null) target.do();
}
}

Thank you very much for the reply! After reading what Fadden said
weeks ago, I happily converted my static inner handler classes to non-
static ones.
Just recently, I was browsing the source code of Handler and came
across this bit of internal Android debugging:
/*
* Set this flag to true to detect anonymous, local or member
classes
* that extend this Handler class and that are not static. These
kind
* of classes can potentially create leaks.
*/
private static final boolean FIND_POTENTIAL_LEAKS = false;
There is some code further down that uses reflection to locate such
subclasses if this flag is true.
My handlers fall into the category of non-static member classes, so I
am curious how such classes could cause a memory leak. My initial
thinking was that handlers could perhaps accumulate in a collection
associated with the MessageQueue. But handlers are never placed into
collections, as far as I can tell. The reference to the handler is in
the message. Clever! (And in any case if the memory leak is due to an
ever-growing collection of handlers somewhere then that has nothing to
do with whether or not the handler class is static or not.)
Just wondering if someone can shed some light on this comment in the
Android source code.
Thanks,
Greg

There's no real difference between explicitly and implicitly passing
the outer-class reference around. Your example above is essentially
doing what javac does automatically.
Staticinner classes have some useful properties, e.g. you know
they're not modifying state in the parent, and you can use
Class.newInstance() with them. There's no performance magic though.
If you're really curious, write it both ways in trivial source files,
compile them, then view them with javap -private -verbose Class or
dx --dump Class.class. They should look about the same.

Re: [android-developers] onSaveInstanceState() killed by OS
Hi Andrew, The answers you got are correct. You should spend as little time in onSaveInstanceState (or any other onX callback method) as possible. Preferably a few milliseconds. I don't know what your app does, but it looks like you try to save user supplied information (either in a file or online) and you chose the onSaveInstanceState callback to do so. Don't use this callback for this purpose. The onSaveInstanceState should only be used to enable you to recreate the activity (i.e. what's on the screen) later exactly as it appeared just before its process got killed. No more, no less. This means, as Magouyaware said, saving nothing more than simple values from Views/controls/etc. If you need to persist user-provided data (on file, online), then use another mechanism. If saving this user-provided data could take a relative long time, use a service (Service, better would be IntentService and if you're paranoid a wakefull IntentService - ask Mark about this one :-) - is even better).

when you obtain a Message and don't post it right away but keep it
somewhere (for instance in a static structure) for later use.
If you want to use the equivalent of an inner-class but not risk a
leak, here's a simple pattern:
class OuterClass {
class InnerClass {
private final WeakReferenceOuterClass mTarget;
InnerClass(OuterClass target) {
mTarget = new WeakReferenceOuterClass(**target);
}
void doSomething() {
OuterClass target = mTarget.get();
if (target != null) target.do();
}
}
}

Thank you very much for the reply! After reading what Fadden said
weeks ago, I happily converted my static inner handler classes to non-
static ones.
Just recently, I was browsing the source code of Handler and came
across this bit of internal Android debugging:
/*
* Set this flag to true to detect anonymous, local or member
classes
* that extend this Handler class and that are not static. These
kind
* of classes can potentially create leaks.
*/
private static final boolean FIND_POTENTIAL_LEAKS = false;
There is some code further down that uses reflection to locate such
subclasses if this flag is true.
My handlers fall into the category of non-static member classes, so I
am curious how such classes could cause a memory leak. My initial
thinking was that handlers could perhaps accumulate in a collection
associated with the MessageQueue. But handlers are never placed into
collections, as far as I can tell. The reference to the handler is in
the message. Clever! (And in any case if the memory leak is due to an
ever-growing collection of handlers somewhere then that has nothing to
do with whether or not the handler class is static or not.)
Just wondering if someone can shed some light on this comment in the
Android source code.
Thanks,
Greg

There's no real difference between explicitly and implicitly passing
the outer-class reference around. Your example above is essentially
doing what javac does automatically.
Staticinner classes have some useful properties, e.g. you know
they're not modifying state in the parent, and you can use
Class.newInstance() with them. There's no performance magic though.

[android-developers] OEM-Official ADB USB Driver support (rant)
One of the most vexing problems over the years: Official ADB USB driver support by OEMs. With the exception of a few, every new device coming out seems to be missing the ADB USB drivers. Even Nexus devices. And once out, they may not even be available naked from the official source, as they should be. I got a Nexus 7 the other day and there still doesn't seem to be OEM- official ADB USB driver support? Sure enough I got the Asus drivers installed that cover the Transformer Prime, but the Nexus 7 draws a blank. Or am I missing something (discount XDA developer's)? -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Listener object referece after removing the view
Why not override the finalize method in Java?
protected void finalize() throws Throwable {}
Maybe stick a Log statement in there and put a breakpoint on the Log
statement?
When it gets called, that's when it's ready for collection.

I dont need the view and listener references any more, once user changes

[android-developers] JellyBean systrace in cygwin problem, does not write trace.html
Using systrace, I am trying to create a system trace file as
demonstrated in the Google I/O session For Butter or Worse.
Configuration: Galaxy Nexus / JellyBean 4.1.1 (JR003C).
Windows 7 SP 1 with Cygwin and Python installed, which is different
from the demo in the session where they use a Mac.
When I run ./systrace, I get a binary dump in the console and a
trace.html is not written. I tried to pipe the output to a trace.html
file, but the output is not HTML. Below the output (abbreviated).
Anybody have any ideas?

[android-developers] Re: Sole Trader in Germany?
Let the German bank account owner try to figure that one out. He could first of all ask his bank for free. Be warned that the bank might be not amused when that account got opened under false pretenses (see http://europa.eu/youreurope/citizens/shopping/banking/opening-bank-account/index_en.htm ) Then he can go to the local tax office and ask there for free. And if you want to be super-safe, hire a lawyer (best bet). My guess is the following: since the EU makes these efforts for harmonizing business between EU countries it is OK to open a business bank accounthttp://www.businesslink.gov.uk/bdotg/action/detail?itemId=1083972719type=RESOURCESin Germany (or any other EU country). But you have to tell the bank and negotiate with them because there are different conditions depending on the bank account and business type. In case of businesses there are additional conditions that require you to proof that your business is valid. Since your business is not located in Germany, and having your business at a real German address is a requirement for running a German business, I'm pretty sure that you do not have to pay German taxes. But that can be definitely cleared up by asking the local German tax office and / or a lawyer. If the situation turns out to be too cumbersome you may consider opening a business bank account in the UK for examplehttp://www.bba.org.uk/customer/article/bank-account-access-in-the-uk-for-non-residents/banking-abroad/ . Or you could found a subsidiary company in another EU country. There are at least efforts for eliminating double-taxationhttp://ec.europa.eu/taxation_customs/taxation/company_tax/parents-subsidiary_directive/index_en.htm#elim. However, usually you need a real business address (not just a PO box). If you are considering that option, don't found your company in Germany. It is possible, but the laws and requirements there are a total pain in the backside for small businesses. While googling around I found a website that says they help companies abroad with founding a UK based LLC and they serve as a proxy forhttp://www.sfsgo.com/nonukclientinfo.aspgetting you a real business address and local representatives. I'm not sure how shady that business is (it certainly looks fishy to me). But anyway, in the past 10 years or so, UK was pretty popular for setting up companies from abroad. For some time the only thing you needed was an address there. I think due to heavy abuse they made things a bit stricter in the meanwhile.

[android-developers] Re: Sole Trader in Germany?
In addition to what I said: the German bank account owner might get into trouble with the German tax system because of the money you earn for him. He is actually obliged to tell the tax office about any kind of income he has and in my book that money you earn counts as his income, since he owns the account. I don't know how the German tax office networks with German banks and whether they try to peek into transactions but I think that's a possibility for uncovering fraud. I don't think that you and your company are at any risk here, but your German friend might be. In my opinion the only sane way out of this situation is that the German account owner terminates that account and that you open a real business bank account in your company's name. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: static vs non-static inner classes
The problem is with a non-static inner class is that you don't 'see' the
implicit reference to the outer instance (OuterClass.this). It is easy to
forget about this one and later realize what problems it causes.
Usually,
when the lifetime cycle of an inner class matches the lifecycle of the
outer class (e.g. OnClickListeners,etc, or BroadCastReceivers that are
unregistered in the (outer) Activity's onDestroy), I make it non-static.
When the lifetime cycle of an inner class does *not *match the lifecycle of
the outer class, I make it static. If a reference to the outer class'
instance is needed, I either 'wrap' it in a WeakReference or create
specific methods for detaching the outer instance from the inner instance.

[android-developers] Re: stroke color
I'm not sure what you mean. You can call Paint.setColor() and provide an ARGB encoded integer as argument. You can use the Color class for constructing such an int with helper methods. Or you can call Paint.setARGB() for specifying the individual color channels. If you want to draw a shape with different stroke and fill colors you could use two draw operations for that and change the Paint object's color and style in between.

Re: [android-developers] Re: OEM-Official ADB USB Driver support (rant)
Since no-one's offered you try using Linux, I'll do that now. Some devices still need some magic in the udev config file, but most don't. I'm seeing a big difference in how fast Eclipse launches an app after it's been built, it's much faster on Linux than on Windows (same computer, same Eclipse versions). You can make up for the increased efficiency by trying different distributions, kernels, desktop environments, or figuring out what configuration file controls X, Y or Z that could be easily changed by pointing and clicking on Windows or Mac. Faster launch time is the killer difference for me though. And back to Windows, some manufacturers started posting their ADB drivers to the Windows Update Center, so they install automagically. Out of the devices I have, Sony Ericsson Xperia Arc was the first one, and today I saw it with my Galaxy Nexus. The funny (and sad) part is that the adb driver appears to be the same, it's just the PNP ID's that are different. -- K 2012/7/21 JP joachim.pfeif...@gmail.com I figured somebody was going to offer that.

Hence, in a nut-shell, my problem -- real-time!. I still need to work out the frequencies and corresponding amplitudes for different object densities. I am obviously in the feasibility stage of development. Someone suggested to me that Android devices (and most real-time cell/pda devices) might contain an embedded MIB Module (Management Information Base) *http://en.wikipedia.org/wiki/Management_information_base*. If this is the case, then it could be a simpler matter of extracting the information from the MIB-module and doing the spectral analysis at that point. ie, it would look real-time. I am looking for what might be proprietary information (schematics, etc) of the guts of the Android or even iPhone, etc to see exactly how the transmitted and received signals are handled and digested, even for simple voice calls. This whole issue might be a lot simpler than I think, but it usually never is. Thanks for any and all comments and suggestions .

[android-developers] Logcat without ADB or even USB drivers
I have a bug that so far only shows up on this obscure Chinese tablet. There are no OEM USB drivers for this device, so I can't use Logcat the usual way. Is there any other kind of logging that is similar to Logcat that I could use to log some events in the code? I could write my own logging and display facility in the app itself, but I would rather not do all that work if there is another way. -- You received this message because you are subscribed to the Google Groups Android Developers group.

is the device rooted? you should be able to pipe the logcat on the device to a text file.
