Sherlock runs on android 2.1 and above.

Not sure what you mean by "other youtubes" - AFAIK, there is only one.

Why?  If I want an app that turns off the data connection on a timer
function or reading location manager information or I just don't like
digging through a settings menu, why should I be at the mercy of an
OEM's implementation?

And if turning off the APN is "not good" why are there APIs that let
you catch the NEW_OUTGOING_CALL intent and consume it so
the call isn't dialed, or the incoming SMS messages, or holding a
wake lock.

1) "ur" is not a word.  I'm assuming you were trying to spell "your".

2) No.  If you can't be bothered to ask your questions here, don't expect
   anyone else to bother with them, either.  Nothing personal...just how
   it generally works, and has worked for decades on e-mail lists, Usenet
   newsgroups, etc.   You MIGHT get answers by posting this way, but you
   are FAR more likely to get them if you post your question correctly.

And if you find the above advice (intended only to be helpful) offensive,
well, that's a personal problem (yours).

Re: [android-developers] APP2Friend ?

Now it seems that this particular app has been removed from the Play Store.

But after I was made aware of this problem, I see that there are SEVERAL 
other apps doing the same thing.
I tried a few of them, and they work, enabling users to send paid apps to 
friends - for free.

Why Google doesn't remove these apps I don't understand.

[android-developers] Integrating Android build system with Test tool

[CharuhasV]

Hi,

Is there is any way I can integrate Android build system with Android 
testing framework?
i.e When I build my android project, It would automatically run my unit 
test cases and if any unit test case fails the build would give the error.

The straight forward way can be to write a script which does this. But I 
wanted to know if similar utility is already available in Android.

Thanks,
Charuhas Vidwans.

[android-developers] ListFragment not retaining scroll position after orientation change

[havexz]

After struggling with it for a day, this is what i found.

I am using ListFragment and Loaders with support library.

If I used same/standard Loaders code in a normal Activity it ListView 
maintains its scroll position very precisely. 

If I am using same/standar Loaders code in ListFragment then if I scroll 
position is complete lost afte orientation change. And it ListView is 
scrolled to top.

I also noticed that 'savedInstanceState' is coming as 'null' to for 
'onCreate', 'onViewCreated' and 'onActivityCreated', even though I am 
saving some state in 'onSaveInstanceState'.

Attached is the code for fragment.

I am just wondering...am I alone..:-/...?

[android-developers] Re: Is it possible to reduce the variability of camera shutter lag time?

[gjs]

Hi,

I am curious about how you are performing & measuring timings between 
subsequent shots as there may also be some variability according to your 
method(s). For example, I found that using a Timer object there was some 
variability in when the task was actually run, sometime by a few hundred 
milliseconds. I had done some related work a while back trying to closely 
synchronise the cameras shutters of multiple Android devices connected via 
Bluetooth. This was successful to a degree but would sometimes lock up a 
Nexus S entirely, if the intershot delay was less than a few seconds.

Regards, the other gjs.

Re: [android-developers] slick button?

For a button?  You don't want to do that, that is a huge amount of overhead
just for a button.

No, don't.  That doesn't fix the problem, just hides it in some of the
common situations.  (This also breaks many behaviors around configuration,
such as selecting the right value for any resource that varies based on one
of these configurations.)

The correct solution is to write your activity correctly so that it does
the right thing when it is re-created from a previous saved state.

Re: [android-developers] Scanning root of SDcard does not work on 4.1

[Dianne Hackborn]

If you are running on a non-user build, as of JB you need to require the
new read external storage permission.  On a user build, you may have
enabled this restriction in developer settings.

Re: [android-developers] Is setting invalid APN the only way to disable mobile network connection?

[CJ]

Hi, I understand. There are many popular app that automate system task with 
big user base.
APNDroid, JuiceDefender, Motorola SmartAction etc so many. So likely there 
is no answer other than using what APNDroid is using and it is likely going 
to be future version proof.

[android-developers] Re: Scanning root of SDcard does not work on 4.1

[Doug]

In JB, they changed the mount point for external storage to 
/storage/sdcard0.  At least this is the case for the Galaxy Nexus and Nexus 
7.  So if you're not seeing the directory, double check it.  Still, 
/mnt/sdcard should be a symlink to /storage/sdcard0.

I'm noticing that you're taking the file object from 
Environment.getExternalStorageDirectory, then turning that into a string, 
then turning it into a File again.  That's not necessarily wrong, but you 
might want to reconsider that.

cameraBitmap.getHeight(), Bitmap.Config.ARGB_);
Canvas cam = new Canvas(back);
cam.drawBitmap(cameraBitmap, matrix, null);

You have better chances of find help on such issue on Eclipse ADT forum.

Re: [android-developers] Re: Change the textcolor of a listview item in onCreate method.

[Justin Anderson]

And... you are going about it the wrong way...  You don't want to change
the listview's children directly.  Make the state part of your data model,
write a custom adapter and implement the getView() method to change the
color of the text based on the state of the item in the adapter.  If you
need to change the state of an item, change it in the adapter and call the
adapter's notifyDataSetChanged() method...

Since you requested the default sound, does your device have a

@your second comment: I kind of doubt that if you require a shared

to have problems.

As for using monodroid, I don't really feel like that's a viable
option, but even if it is, you'll have to check with another forum,
this group is exclusively the SDK.

If it's in C#, it probably requires .NET, and you can't do .NET on Android.

[android-developers] Re: RotateAnimation wrong in android 4.0

[bob]

 

Sounds more like a "change in dpi" issue.


The 4.0 phone is probably xhdpi, and your stuff is in the hdpi folder, so 
it gets scaled.

Re: [android-developers] Is setting invalid APN the only way to disable mobile network connection?

[Kristopher Micinski]

This goes in the category of "apps modifying the system."

Your app shouldn't be able to modify the system.  While this sounds
funny, it's true.  Sure, you can write such apps and hack around
things below 2.3.3, but do you really expect your app will really be
used for that long, then?

 Hi,

 I have been googling for a while able the best or right way to

 I tried the following code which is all over Stackoverflow and is
 working fine for gingerbread and higher:

 private void setMobileDataEnabled(Context context, boolean enabled)
 throws Exception {
 final ConnectivityManager conman = (ConnectivityManager) context
 .getSystemService(Context.CONNECTIVITY_SERVICE);
 final Class conmanClass =
 Class.forName(conman.getClass().getName());
 final Field iConnectivityManagerField = conmanClass
 .getDeclaredField("mService");
 iConnectivityManagerField.setAccessible(true);
 final Object iConnectivityManager = iConnectivityManagerField
 .get(conman);
 final Class iConnectivityManagerClass = Class
 .forName(iConnectivityManager.getClass().getName());
 final Method setMobileDataEnabledMethod = iConnectivityManagerClass
 .getDeclaredMethod("setMobileDataEnabled", Boolean.TYPE);
 setMobileDataEnabledMethod.setAccessible(true);

 setMobileDataEnabledMethod.invoke(iConnectivityManager, enabled);
 }

 Somehow I didn't find a way to do the same thing for Android 2.2 and
 below. Many mentioned to change the APN name to something invalid like 
 what
 app APNDroid did but is that the only way?

[android-developers] RotateAnimation wrong in android 4.0

[Faust Nijhuis]

Hello ,

There is a problem when using RotateAnimation in android 4.0.
On all pre  android 4.0 versions it works ok.

The RotateAnimation is good on a android device with a HVGA screen.

The RotateAnimation is not good, the center point is shifted, on devices
with a other screen size.

This is my code:

*final RotateAnimation animRotate =*
* new RotateAnimation(0.0f, 360.0f,*
* RotateAnimation.RELATIVE_TO_SELF , 0.5f,*
* RotateAnimation.RELATIVE_TO_SELF , 0.5f);*


I can make the RotateAnimation working correctly for WVGA, i have to change
0.5f to 0.f:

*final RotateAnimation animRotate =*
* new RotateAnimation(0.0f, 360.0f,*
* RotateAnimation.RELATIVE_TO_SELF , 0.f,*
* RotateAnimation.RELATIVE_TO_SELF , 0.f);*

I think it has something to do with scaling but can not find anywhere what
the solution is.

Does anyone know of this problem, is it a bug?

Faust

[android-developers] Re: CAN-SPAN?

[Nobu Games]

As far as I understand the first argument: it is whatever object you want 
to use for tagging that span of text. It's up to your app to come up with 
the right interpretation. If you want to use the span for formatting you 
can use one of the 
CharacterStyleobjects
 as first argument.

Here is a tutorial about rich style formatting with spannable strings:

[android-developers] CAN-SPAN?

[bob]

I'm trying to learn about SpannableStrings, and it is boiling down to this 
setSpan method:

http://developer.android.com/reference/android/text/SpannableString.html#setSpan(java.lang.Object,
 
int, int, int)

However, of course, the method is completely undocumented, and it is not 
clear what ought to be passed into the first

Re: [android-developers] android:accessibilityFocusable attribute in a layout-xml produces an error

[Streets Of Boston]

Thank you Mark.

I've been trying to update our app to the latest and greatest in JellyBean 
accessibility. This is one issue I encountered.

I've also been trying to implement some AccesibilityDelegate 
and AccessibilityNodeProvider implementations of our own custom views to 
establish a virtual view hierarchy, but without any success. Even the 
samples (ApiDemos) for accessibility can't handle the accessibility-focus 
events well (hover events seem to work somewhat better). I wish there were 
some proper examples - that work! - of how to make a fully accessible (also 
on JellyBean) custom view with a custom virtual view hierarchy.  Do you 
know of any?

Seriously it's a mobile computer with compromises between

If you try to maximize (remove the limits from) any one of the above 
you adversely affect the others.

Re: [android-developers] Is setting invalid APN the only way to disable mobile network connection?

[CJ]

The permission needed is 
Android 2.3 and above can do that with the code I supply. I am asking a 
question how to do it for version below 2.3.

Many apps are doing it, the most popular one I mentioned was JuiceDefender:

Re: [android-developers] android:accessibilityFocusable attribute in a layout-xml produces an error

[Streets Of Boston]

hi Mark,

I found it in the layout editor (using Eclipse). It shows up as a property 
and you can select 'auto', 'yes' or 'no'. 

If this is not the way to do it, how would one prevent accessibility focus 
to a particular control?

Re: [android-developers] Is setting invalid APN the only way to disable mobile network connection?

[Robert Greenwalt]

How to do the permission?  That's not your issue - the platform needs to do
it.

How to turn data on/off?  It looks like you'll need a mix of methods.
 You're using undocumented methods from the past and present and they may
change in the future.  You can do different things dependent on the version
of the platform.

There should not be arbitrary limits mandated by an opaque entity who

Re: [android-developers] Is setting invalid APN the only way to disable mobile network connection?

[Joven Chiew]

Well, yes and no. I do understand it is a little weird because an app can
turn on mobile data out of user will. But we are Android :) user can decide
to uninstall ill intention app. Think of it in another way, if my phone
battery is critically low I would want to turn off my data so I can still
receive sms/phone and the battery will last a lot longer. If I keep it in
my pocket and didn't realise that my battery is low, I wouldn't have a
change to switch data off. There are many app such as the famous Juice
Defender that control what happen when battery is low etc, and many apps
has ability to control it. I am sure it is there just not being documented.

 private void setMobileDataEnabled(Context context, boolean enabled)
 throws Exception {
  final ConnectivityManager conman = (ConnectivityManager) context
  .getSystemService(Context.**CONNECTIVITY_SERVICE);

Re: [android-developers] Is setting invalid APN the only way to disable mobile network connection?

[Robert Greenwalt]

If the app is granted permission by the user it would be ok.  And apps that
do intelligent things in this area may be useful and welcome.  Without
permission limits though, yeah this could be a problem.

Re: [android-developers] Is setting invalid APN the only way to disable mobile network connection?

[Nick Kralevich]

Hmm  From the platform's point of view, this sounds like a denial of
service attack against other applications on the device. One application
shouldn't be able to interfere with another application's network
connectivity without the user being involved.

First, I'm 99.% certain that you can't "convert" a DLL to a
shared library (.so).  You'll have to recompile the library in the NDK.

Second, for NDK questions, the correct group to ask your question in is
android-...@googlegroups.com, NOT this group.  This group is for
developing apps for Android using the SDK (or for a project with both,
for the SDK side of the app).

[android-developers] onSaveInstance state in activity and fragments

[user123]

Hi,
I have an activity which contains 2 fragments. I want to save certain state 
of the activity and also of the fragments, in order to restore if the 
activity, or the fragments, are destroyed.

So I'm using onSaveInstanceState both in the fragments and in the activity, 
and take the data of the bundle passed to onCreate or onCreateView.

This works well besides, when the activity is destroyed. Then in restores 
it's own data, but, since in onCreate() I instantiate the adapter and the 
fragments again, they get no state.

How do I solve this?

Thanks in advance.

[android-developers] xmlns

[bob]

So, in all my layout files I have this:

xmlns:android="http://schemas.android.com/apk/res/android";

Admittedly, I only semi-understand that.

Here's one thing that confuses me:

When I go to http://schemas.android.com/apk/res/android, there is nothing 
there.

Is this just some magic fake URL that's built into Android?

I was just going to point you to the right page in the dev guide, but I
don't remember if there even is one (I learned this from a book, "Pro
Android Media").  Be advised that with larger bitmaps, you can easily
cause an Out Of Memory error and, if that isn't caught, a force close,
so if you need to do this with LARGE bitmaps, you'll have to use the NDK.

   // blend src1 and src2 into dest (must be same size and, I think they
   // have to be the same configuration, too, e.g., both ARGB_)

   Bitmap dest = Bitmap.createBitmap(width, height, src1.getConfig());
   Canvas canvas = new Canvas(src2);
   Paint paint = new Paint();

   canvas = new Canvas(src2);
   paint = new Paint();
   canvas.drawBitmap(src1, 0, 0, paint);
   paint.setXfermode(new 
PorterDuffXfermode(android.graphics.PorterDuff.Mode.SRC_OVER));
   canvas.drawBitmap(dest, 0, 0, paint);

PorterDuff has quite a few different modes, so check out the dev guide's
page on PorterDuff.Mode for more information.

[android-developers] convert dll to so and include into android project

[Károly Holczhauser]

Hello developers ! 

 I have a huge problem, and I don`t get over it, so please if you are able 
give me some help.:
we have a microcontroller library in c# which has been converted out into a 
DLL file. It is okay, and nice. I have to write an Android "remote 
controller" applicaiton for the microcontroller, so I have to include the 
DLL into my Eclipse project, to be able call functions in it. It is not 
possible ( i was not able to do :) ) so I`m trying to convert the dll by 
the android NDK, because it is product and .so file. 

My first question is it a good way ?

After i have an so file, I woud like to include in to my Eclipse project, 
but I was not able to do it :( 

Is anyone have any idea, or do you know any solution ? 
Thank you so much, 
Karoly

Re: [android-developers] Is setting invalid APN the only way to disable mobile network connection?

Hi, I am working on a app to automate some setting eg. to perform certain 
action such as disable mobile data when battery is low or night mode etc.
There are app in the market that able to disable/enable mobile data 
connection like SmartAction and a few more. I also dislike the alter APN 
method so I am looking for better alternatives.

[android-developers] Re: Audio Capture

[bob]

The problem is likely that your app is still dormant.  It has not exited.

What has happened is that it is paused, and when you go back to it, 
onResume is called…  not onCreate.

You can make your app truly exit when the back button is pressed by adding 
this to your Activity class.

@Override
public void onBackPressed() {

System.exit(0);
}

Some people consider this bad, so I'm only recommending it as a diagnostic 
aid.

Maybe a wake lock will help you?

PowerManager.WakeLock wl = pm.newWakeLock(PowerManager.FULL_WAKE_LOCK,

wl.acquire();


Or maybe this?

[android-developers] Is setting invalid APN the only way to disable mobile network connection?

[CJ]

Hi,

I have been googling for a while able the best or right way to 
disable/enable mobile network.

I tried the following code which is all over Stackoverflow and is working 
fine for gingerbread and higher:

private void setMobileDataEnabled(Context context, boolean enabled)
throws Exception {
final ConnectivityManager conman = (ConnectivityManager) context
.getSystemService(Context.CONNECTIVITY_SERVICE);
final Class conmanClass = Class.forName(conman.getClass().getName());
final Field iConnectivityManagerField = conmanClass
.getDeclaredField("mService");
iConnectivityManagerField.setAccessible(true);
final Object iConnectivityManager = iConnectivityManagerField
.get(conman);
final Class iConnectivityManagerClass = Class
.forName(iConnectivityManager.getClass().getName());
final Method setMobileDataEnabledMethod = iConnectivityManagerClass
.getDeclaredMethod("setMobileDataEnabled", Boolean.TYPE);
setMobileDataEnabledMethod.setAccessible(true);

setMobileDataEnabledMethod.invoke(iConnectivityManager, enabled);
}

Somehow I didn't find a way to do the same thing for Android 2.2 and below. 
Many mentioned to change the APN name to something invalid like what app 
APNDroid did but is that the only way?

[android-developers] android:accessibilityFocusable attribute in a layout-xml produces an error

[Streets Of Boston]

Hi,

I have a text-view next to a seekbar. The seekbar is accessible and 
announces its current value. The text-view also shows this value. 
For accessibility, I'd like to make the text-view not 
accessibility-focusable, since the seekbar already is (no use in stating 
the same thing twice).

However, when adding *android:accessibilityFocusable="no"* to the layout 
xml, I get this error:
*No resource identifier found for attribute 'accessibilityFocusable' in 
package 'android' page_slider_layout.xml /KnfbBlio/res/layout line 37 Android 
AAPT Problem*

The project build target is 4.1 (api level 16). 
The targetSdk in the AndroidManifest.xml is set to 16 as well.

Any idea what the problem could be?

Thanks!

It doesn't matter. They can load you app with malware, put it on some 'sharing'
site and it will look like it came from you. It will even update
cleanly on top of
your own app.

So:

 * put a good password on your keystore
 * put your keystore in a safe :)
 * put a copy in another safe, not in the same building

And you should be relatively safe :)

[android-developers] Re: Is it possible to reduce the variability of camera shutter lag time?

[greg]

Thanks for the suggestions. Based on them I tried disabling all the camera 
auto parameters. There is still a range of about 0.2 s in the shutter lag 
time. In this application (and perhaps there are others), I'm more 
concerned about the variability and not the average duration of the lag 
time. I have posted a feature request to the Android issue tracker to add 
an optional minimum shutter time argument in Camera.takePicture() that 
would delay the shutter if it were ready before the specified minimum. If 
you think you might find that extra control helpful in a future 
application, "star" the feature request at 
http://code.google.com/p/android/issues/detail?id=35785

Thanks! --Greg

 Given a known periodic motion (e.g., walking), I'd like to take a full 
 resolution snapshot at the same point in the motion (i.e., the same time 
 offset within different periods). However on the Nexus S (currently 
 running 
 OS 4.1.1 but the same was true of previous OS versions), I'm seeing so 
 much 
 variability in the shutter lag that I cannot accurately plan the timing of 
 the snapshot. Is there anything I can do in the application to reduce this 
 shutter lag variability? (In this application, the mean lag can be any 
 duration but the standard deviation must be small ... much smaller than 
 the 
 0.5 s standard deviation I am seeing.) I'm hoping someone has a clever 
 suggestion. If I don't get any suggestions, I'll post a feature request in 
 the Android bug tracker.

 I've posted the same question (and showing a histogram of camera 
 shutter lag times) at

[android-developers] Re: Use of weak password to protect Android keystore

[howa]

But suppose they don't have the login into my Android Developer Console, I 
don't need to worry?

Re: [android-developers] Re: Transporting to Server Problems

[Evan Ruff]

Right, the thing is, I NEVER get the the problem when I'm testing. It's
only happening in the field.

What's really weird is that it's just not THAT much data. I mean, I'd say
the average payload size is <200kb!

Thanks!
