[android-developers] Re: Animations in the list view
I have tried one way of doing this kind of animation.I have taken 2 listviews and made first list view's visibility gone.Then i have taken one separate layout( the same custom layout i am using for the listview )and trying to translate that layout from middle to top and once it reaches to top and making it's visibility to gone.and the same time when the view is translating, i am sliding down the list also and once the view's animation ends i am setting list animation to fillAfter = true and fillEnabled=true and list1.setVisibility = gone and list2.setVisibility = visible sothat list2 should be visible but what happening is list1 is not getting gone it still be there because of the bug when we use fillAfter = true and fillEnabled=true.How can i make my list1 visibility to gone ?

Re: [android-developers] Correct way to implement Activity onDestroy()?
Basically, as long as you aren't hanging static Activity references you should be fine. The main activity will be thrown away upon its destruction, at which point the Activity will be thrown away: along with its contents. Of course, if you're holding onto Views elsewhere that's bad (i.e., don't hold static refs). kris On Mon, Jan 14, 2013 at 1:42 AM, Greenhand cooperateonl...@gmail.com wrote: I read http://android-developers.blogspot.tw/2009/01/avoiding-memory-leaks.html about avoiding memory leaks.

Re: [android-developers] Correct way to implement Activity onDestroy()?
Thank you. Another related question, in section 5. Implement a more intelligent AsyncTask dealing with screen orientation of http://blog.doityourselfandroid.com/2010/11/14/handling-progress-dialogs-and-screen-orientation-changes/, it has private AsyncTaskComplex activity in ListFresher as a member variable. Shouldn't it be null out because it is not a static Activity references?

Hi, AFAIK, only way around the problem is to introduce a proxy renderer.

[android-developers] Re: Animations in the list view
I think this is not very different to a question we had a couple of weeks ago. This is what I would do: - I would not use 2 ListViews. I would leave the original ListView underneath and dynamically create a new View that was a single RowView and put that on top and slide it around. - I would not insert an extra row into the original ListView. Instead find the child view at the top of the list and double the height of it. Make sure the gravity of the content is such that is sticks to the bottom of the view. - Slide the dummy row view up until it lies directly over the top (blank) part of the child view. - After the animations have finished insert a new Row into the List at the insertion point, change the child view height back to a single row height and destroy the dummy row view. I think that should give you the appearance you want. Judging from the neutral background and lack of row dividers I'm guessing whoever wrote the sample behind your youtube example did something similar.

Re: [android-developers] Toast not showing on Samsung Galaxy S3 (latest update 4.1.2)
What Context are you using? Is it the Activity, or something else? If it is not the Activity, try switching to that and see if the behavior changes. I wouldn't expect that to have an impact, but, then again, I wouldn't expect your problem, either.

Re: [android-developers] Re: BouncyCastle signature value does not match with dotNET signature value.
Hi Nikolay and Jason... Your summary is correct Nikolay: I sign with privatekey to verify the sender. * did you normalize properly? - Yes... I use a very simple plain text, without especial characters, CR, TAB or LF. * does the raw (byte array) signature match? - I'm not sure about this, but the digestvalues in dotNet and BoucyCastle are identical. - A question: How to cipher digestvalue directly with the privatekey? * are you using the same options for Base64? There are subtle variations here (padding character, line breaks, etc.). - The signatures values are very different. I replace the tag in BC file by dotNet signature value and the webservice returns OK. It's a mystery!!! Below, the two exemples of the signature. Thanks in advance.

Re: [android-developers] Toast not showing on Samsung Galaxy S3 (latest update 4.1.2)
Hi, A few suggestions: - I would verify that your code is actually executed (I,E, the code statements in your original post). - Verify no exceptions are thrown. Make sure your code segment is housed in try/catch block. - Add statements to the Toast object and ask it to report the x/y coordinates, gravity, etc. Most unexpected behavior is either in the application code, or the application code's interaction with dependent libraries. For example, a prior version of a dependent library always constructed a value. In the newer library version, the value is set to null and not guaranteed to have a value till certain conditions are met. If your application is not checking that values are null before use, you will get unexpected behavior. Hope that helps :) Good Luck Jason -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] GLUtils.texImage2D
Has anyone else noticed that GLUtils.texImage2D seems to want the image to
be upside down?
GLUtils.texImage2D(GL10.GL_TEXTURE_2D, 0, bitmap, 0);
One way to see this is to look at Cosmin Banu's NeHe code here:
http://code.google.com/p/nehe-android/source/browse/trunk/NeHe06/src/ro/brite/android/nehe06/Utils.java
He has this in there:
private static Matrix yFlipMatrix;
static
{
yFlipMatrix = new Matrix();
yFlipMatrix.postScale(1, -1); // flip Y axis
}
And this:
return Bitmap.createBitmap(bitmap, 0, 0, bitmap.getWidth(),
bitmap.getHeight(), yFlipMatrix, false);
I have independently noticed this, and it caused a lot of frustration.
Any ideas how to best solve this? Obviously, if we just fix it, it will
break a lot of old code that relies on its currently incorrect behavior.

Re: [android-developers] Correct way to implement Activity onDestroy()?
After spending considerable time looking at this issue, I strongly suggest that you look into an Intent Service, for any long running task. Using AsyncTasks is just fraught. First of all, onDestroy is only called best effort. If you care about getting it done, you can't do it in onDestroy. Further, as kris points out, onDestroy is, often, called just as your *process* is about to be destroyed. Worrying about allocation of memory in your process, just as it is destroyed, is pretty pointless. There are two issues you need to consider: making your program correct according to Java (If mutable state is referenced from more than one thread, all references must take place holding a single lock - B. Goetz, paraphrased). You also have to be sure that the lifecycles of unmanaged objects (e.g. AsyncTasks) don't interfere with the lifecycles of managed objects (Activities). Nulling out pointers and AsyncTasks that survive screen reorientation (despite the fact that I proposed it myself, at one point) are just Voodoo. G.

You will need to delete the Google Play Services entry in your SDK Manager and reinstall it to see the license agreement.

[android-developers] Do we need a license from MPEG-LA for AVC H.264 MediaCodecs?
Hi there, I am currently working on an app that would utilize the capabalities of the devices H.264 codec exposed via the new MediaCodec API. I assume the vendor's have to pay the respective royalties to the MPEG-LA for shipping a device with an H.264 capable encoder. But is this true? Can I legally (and without paying any extra royalties) use the system encoders? [1] mentions that the rules of MPEG-LA require that if Company A uses Company B's encoder in their product, Company A must pay the fees, not Company B. I know this mailinglist might not be the right address for licensing questions but I just hope any one of you already had to examine this situation.

Re: [android-developers] Correct way to implement Activity onDestroy()?
While you say that Activities only die when the process is about to be destroyed (or usually die), I have heard that this is not the case. This is mostly hearsay from developers and people I work with saying that memory leaks because of this were really a problem, but I'd have to look into it with some examples (of layouts that really use memory, I'm thinking galleries and nested views, etc..) before making any definite calls.

[android-developers] Google Maps v2 causes memory leak
Hi, I have switched to the new Google Maps v2, it works quite well, but after some time I discovered growing memory consumption of my app. After investigation it turns out that the sample application demonstrating Google Maps v2 bundled in android sdk also suffers with growing memory consumption. The worst part is, that after several orientation changes on sample application the app crashes with OOM. The log from example crash is available here http://pastebin.com/Zyje0kfD, but crashes occur on different places. The fastest way to reproduce this behavior is with the Multiple Maps sample, but I get it with Basic Map sample as well, it just takes longer. After getting heap dump and analyzing it in MAT I found that some object from map library holds the memory and is considered as GC root. The hprof file is available herehttps://dl.dropbox.com/u/17342616/android-maps-v2-sample.hprof. I found this problem on Galaxy Nexus with android 4.2 and HTC Desire with android 2.3. I have found nothing regarding this issue on the internet so I'm asking here. Have anybody else detected memory problems and was able to somehow prevent them?

[android-developers] Using APK Signature to detect .apk tampering (Attn: Dianne??)
We've recently implemented anti-piracy code in the latest version of our
app. It checks the digital signature of the APK against our own (known)
signature to see if the app has been tampered with. This is based on a
suggestion made in this post:
https://groups.google.com/forum/?fromgroups=#!topic/android-developers/fPtdt6zDzns
.
Here is the call we're using to obtain the APK's digital signature. As
Dianne Hackborn explained in the thread, the signature is really the
signing certificate's (i.e. our) public key, and this will not change from
build to build:
PackageManager pm = context.getPackageManager();
try
{
PackageInfo info = pm.getPackageInfo( xxx.xxx.xxx.xxx,
PackageManager.GET_SIGNATURES );
Signature[] sig = info.signatures;
String sigstring = new String( sig[0].toChars() );
// Compare this signature with what we signed it with
}
On startup, our app now compares the public key returned by this function
to an internal copy of our correct, known public key. If the comparison
fails, the app posts a notification to our server, then quits. The
notification contains a copy of the incorrect public key.
Our anti-piracy code has been tripped twice. We've gotten the notification
twice. Strangely, the first time was minutes after we uploaded our new APK
to Google Play, before we made the new version public. In the 10 days
since we uploaded this version, our app update has been downloaded and run
thousands of times, with no further notifications.
Then, on friday Jan 11th, we got another notification that our anti-piracy
check has been triggered. In both cases, the incorrect public key was as
follows:
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
I won't post a copy of our own (correct) public key here, but it is very
different from the one above.
We also collect the Android ID of the device being run on. The ID for the
first trip detection (immediately after uploading the .apk) matches the ID
of the detection we go on Friday.
Our conclusion is that some internal Google Play process must be be
repackaging our APK, for whatever reason, then running the repackaged
version. Google Play must clearly be distributing our original, unaltered
APK to end users; otherwise we would get this notification constantly (and
all of our users would be complaining that the app quits on startup!)
But we're mystified as to why we got this notification so soon after
uploading the APK to google play. We can only assume it must be the result
of some internal Google Play process. We can find no other explanation,
especially since the first notification happened immediately after we
uploaded the APK to google play, before we even made it public.
Can anyone confirm whether such a repackaging is part of google play's
normal process for newly-uploaded APKs? If so, this would greatly help put
our minds at ease. If not, can anyone suggest any other possible
explanation for the notification to have been sent?
Once again - the only times our public-key-comparison-failed notification

Thanks.
It would be nice if there was a cleaner failure rather than just showing
you the wrong source. I wouldn't mind some kind of check that prevents you
from jumping to some weird source line without necessarily knowing it.

[android-developers] Any USB-Serial Adapter on Android Phones?
Specifically, for my Note N7000 but interested in more general application as well for a new app. I own a Keyspanhttp://www.tripplite.com/en/products/model.cfm?txtModelID=3914USB-Serial adapter. When I plug it in via an OTG cable, I can see (via terminal window and lsusb command) that the new device is recognized to some extent).

Use android:uiOptions=splitActionBarWhenNarrow on your activity or
application.
I tried android:uiOptions=splitActionBarWhenNarrow at Manifest
file.
This will only take effect in situations where the OS considers the
display to be narrow. Typically, that is a phone-sized screen in
portrait. In all other circumstances, the action bar is not split.
There is no other means of putting an action bar at the bottom.

Re: [android-developers] Re: BouncyCastle signature value does not match with dotNET signature value.

For Java you would get the return value of signer.sign() and convert to hex to compare. Don't remember the details about .NET. - A question: How to cipher digestvalue directly with the privatekey? You'll have to pad it first as per the PKCS#1.5 spec and then encrypt with the private key using Cipher.getInstance(RSA/ECP/NoPadding). Cipher.getInstance(RSA/ECB/PKCS1Padding) should pad it for you. Those might not be available on all Android versions though. However, you are probably having a different problem... * are you using the same options for Base64? There are subtle variations here (padding character, line breaks, etc.). - The signatures values are very different. I replace the tag in BC file by dotNet signature value and the webservice returns OK. It's a mystery!!! Below, the two exemples of the signature. The XML suggests you are using the same key and signing the same hash (digest value). However, the most plausible explanation for getting a different signature value is using different keys. Or maybe you keys are interpreted differently on both platforms? How do you read/pass the key on .NET and Java?

Re: [android-developers] Correct way to implement Activity onDestroy()?
I considered IntentService before; however, I did not found a way to abort IntentService like the AsyncTask#cancel() mechanism. It is why I adapt to Asynctask and wonder about the memory leak issue. If I try to null out the member variables and the activity reference in AsyncTask in onPause(), is it safe? Or, I do not have to null out them unless they are static. I know that onPause() is guaranteed to be called before the Activity becomes killable. G. Blake Meike於 2013年1月14日星期一UTC+8下午11時37分16秒寫道： After spending considerable time looking at this issue, I strongly suggest that you look into an Intent Service, for any long running task. Using AsyncTasks is just fraught. First of all, onDestroy is only called best effort. If you care about getting it done, you can't do it in onDestroy. Further, as kris points out, onDestroy is, often, called just as your *process* is about to be destroyed. Worrying about allocation of memory in your process, just as it is destroyed, is pretty pointless. There are two issues you need to consider: making your program correct according to Java (If mutable state is referenced from more than one thread, all references must take place holding a single lock - B. Goetz, paraphrased). You also have to be sure that the lifecycles of unmanaged objects (e.g. AsyncTasks) don't interfere with the lifecycles of managed objects (Activities). Nulling out pointers and AsyncTasks that survive screen reorientation (despite the fact that I proposed it myself, at one point) are just Voodoo. G.

The main activity will be thrown away upon its destruction, at which point the Activity will be thrown away: along with its contents. Of course, if you're holding onto Views elsewhere that's bad (i.e., don't hold static refs). kris On Mon, Jan 14, 2013 at 1:42 AM, Greenhand coopera...@gmail.com wrote: I read http://android-developers.blogspot.tw/2009/01/avoiding-memory-leaks.html about avoiding memory leaks.

[android-developers] Re: JUnit, TouchUtils, DragDrop and INJECT_EVENTS permission

It turns out the exception is thrown on the first MOVE type motion event - the DOWN before the move works successfully. This brings me to an assumption: Does the new DragDrop framework somehow use a window above the current activity to perform the drag action? Is this window owned by another process than the currently running one? This would at least explain why my tests are failing... Is there a way to fix this and have my tests work properly under these circumstances? Or am I missing something obvious here?
