If anyone from Google is reading: for the love of God, please put a
toast or audible notation
or similar in when this key combination is registered. Since it takes
about 10 seconds
to do anything you have no idea if you've hit the right key
combination or not.

You've just made debugging super-hard by reducing the system logging
access,
please at least make the workarounds usable.

Trying to get the users to use this key combo or attempt to unlock the
secret developer options
(after you've found out if they're on 4.2 or not) is just
embarrassing.

[android-developers] Bluetooth input stream buffer overflows

[Elvira]

I try to read a file via Bluetooth with HTC Desire.

The code for connection is similar to BluetoothChat sample 
http://developer.android.com/tools/samples/index.html.

The problem is in the ConnectedThread when reading files with size greater 
than 5 KB.

This is the run() method of this thread (I removed the code that is 
unnecessary for the understanding of the problem):

public void run() {
  // Keep listening to the InputStream while connected
int bufferSize = 2048;
byte[] buffer = new byte[bufferSize];
int num = 0;
int offset = 0;
while (true) {
try {
// Read from the InputStream

offset = mmInStream.read(buffer, num, 1024);
num = num + offset;

Log.d("Read", "offset = " + offset);

if(num > bufferSize - 1024)
{

num = 0;
offset = 0;
}

} catch (IOException e) {

connectionLost(mAddress);
break;
}
}
}

The local variable *offset* is never greater than 127. And when I try to 
read a 7K file mmInStream.read method blocks after a few seconds and 
doesn't return.

I attempted to use different buffer sizes and read(buffer,0, bufferSize) 
method instead of the one given above. But it doesn't help.

It seems like the inputstream internal buffer is overflowed before the 
reading completed.

Does anyone have an idea how to prevent it?

[android-developers] Bad View Behavior with Changing ListViews

[Evan Ruff]

Hey guys,

I'm having some funny issues with my ListViews. Generally, I have a 
ListView activity where the list view takes up the entire activity. The 
list views are using a custom SimpleCursorAdapter and are using the 
supportLoaderManager to load in the data. The Loaders are connected to 
Observers and the data can be changed by background services. I'm getting 
some weird behavior when the data changes.

When the data changes, I am doing an adapter.swapCursor( null ) while the 
new data is loading.

When the list gets shorter, I'm getting black areas where the previous 
views where, and sometime I'm getting ~ghosting of older views if the 
removed views are at the bottom of the list. Is there some way to enforce 
invalidation or removal of these views?

Is there some step I'm missing?

Thanks!

E

[android-developers] Re: android drag and drop gridview ordering using OnDragListener

[Spiral123]

Hi Frank

I'm not sure I fully understand what effect you are trying to achieve withe 
drag and drop on a gridview (do you have an example to look at by any 
chance?).  I may have done something similar with a custom listview though.

To do drag and drop on my custom listview I don't make a space for my 
dragged object: instead I double the height of the row that is currently 
underneath the dragged object (which I assume is the shadow object in your 
email).  In this way the touch events should continue to be registered. 
 Once the dragged row is dragged more than 50% over the covered row I flip 
the location of the text so that it remains visible.  As soon as the 
dragged object touches the next row I reset the previous one to the 
original height and double the size of the new 'covered' view.

In addition you need to change the height of the original dragged view down 
to 1 pixel rather than changing the visibility of it.

In this way my dragged object always has the listview under it and is never 
'between' two items.

Much as I'd like to claim that I came up with this clever trick myself I'm 
afraid I cannot: if you study the source for Google Music you can see it in 
action therealso if I recall correctly I think the estimable Mark 
Murphy extracted the useful bits from that app to build a custom listview 
class that you should be able to download from his site.

Apologies if I completely misunderstood your problem!

Best,

Nick

An alternative is integrate ACRA in your app which can use the logcat
command to read you app's log entries, no need for adding permissions.

However, it will not work on Android 4.1 and higher. aLogCat can only
report its own LogCat messages, not ones from other processes. That's
because READ_LOGS can no longer be held by normal SDK apps (it is
signatureOrSystem now).

The hidden Developer Options on a 4.2+ device has a "Take bug report"
option that emits the same report as does the magic key combination.

Other than POWER + VOLUME UP + VOLUME DOWN, I am unaware of a way to
collect the bug report on 4.1 without a copy of the Android SDK

[android-developers] Re: SyncAdapter exception that I can't seem to trace.

[Brill Pappin]

I'm actually not calling any AsyncTasks at all in any part of the 
application *yet* and thats why the error was confusing me.
That exception appears to be inside the Android API and popped up when I 
made the provider multiprocess (via the manifest).

When you have that setting true, you are essentially telling the OS that it 
can create threads as needed for the provider, but the new threads don't 
have a proper environment.
So, my guess its a bug in android, but I never had the time to go and try 
and find out if that is the case or not. I can tell you it was happening in 
ICE but not JB, which makes me think it was eventually fixed.

[android-developers] Send bug report from 4.1

Hi 

>From discussions previously here, I am aware that Android 4.1 has rendered 
tools such as Sendlog worthless for collecting log cat logs. 

There was also mention of some secret keystrokes that might produce an 
error log. Something like power + volume up+ volume down. On Galaxy Nexus. 
I can't really push both volume up and volume down at the same time sine 
they are on a rocker type switch. I think I got it right once but I was 
lucky, and I think the method will be . There was also talk of making a 
more user friendly way in settings to do this. 

Is there any procedure that will work on, say, Razr Maxx HD, or ASUS 
Transformer TF700T.

I of course know that the real solution is to write my own log collection 
dialog which will read from my own apps log only on 4.1 and above.  But I 
am not inclined to tell a customer "Just wait till next month's release" if 
there are some alternate ways of diagnosing the problem.

You can use Android AlarmManager service to create alarm, you get a

I am not sure whether it suits your requirement with sqlite but in general

Why don't you not start the video and see if it updates once a second?

It sounds like what you want is a recording studio.  Maybe a soundproof

Make sure you don't let your brother in either.

Re: [android-developers] Re: UI getting slow on video playing

[Shashidhar]

I am not running the app on a mobile phone or a tablet. I am running it on
a smart android decive which has HDMI output and you can connect it to TV
and see the UI on the TV. Can the processing speed limitation of the device
be the reason for slow UI updates??

[android-developers] Re: Time Based Trigger in Android

[Kristopher Micinski]

You should not cross post: android-platform is for platform development only.

You can do this easily using an AlarmManager: you hand it a
PendingIntent, and it fires, you catch it in a receiver and
everything's fine.

   OrderDate : Yesterday
order 1
 Item1
  OrderDate : SomeDay

Explanation:  Many orders with their order numbers.

Single day can have multile orders.

Each order can have many items.

If the order date is same day , Order Date is displayed only once.

why don't you use Google for a basic socket stuff that has nothing to
do with android?

[android-developers] UI getting slow on video playing

[Shashidhar]

Hi,
 In my application, I am majorly doing 2 things.

1) some part of the screen plays video
2) The remaining part of screen has a set of text views and I am updating
them every one second.

For playing video, I am using surface view approach and for updating
textviews, I am using an async task which updates UI in onprogresschanged()
method every one second.

With this approach, the textviews are not getting refreshed with the latest
data every one second. The refresh rate is keep on changing. Some times
they update for 10 sec etc.

When I comment the video playing code, the textviews are getting updated
every 1 sec. properly.

Can any one suggest me a approach such that both the video playing and
textview updates on UI occur properly with out any delay?


Thanks,
Shashidhar

[android-developers] Re: Speaker Problem

[André Lima]

SOLVED.

Reading the jelly bean code source, i've found this code

// This is not an error but might cause users' confusion. Add log just in 
case.
Log.i(LOG_TAG, "Forcing speaker off when initiating a new outgoing 
call...");
PhoneUtils.turnOnSpeaker(app, false, true);

So that's it, in version 4.1 android forces speaker off in incoming and 
outgoing calls.
My solution is turn on the speaker in my call state broadcast receiver, 
after start to make a call

[android-developers] Re: what does it mean? - java.lang.SecurityException: Unable to find app for caller android.app. ApplicationThreadProxy@42b3bcc0 (pid=28461) when publishing content providers

[b0b]

This means there was an error communicating with another process handling 
an Intent. 

The stack trace here is confusing and doesn't show the real cause of the 
problem.

For example i've seen this error happen sending an intent with intent 
extras being too big, bigger than max transaction size (1Mb).

To debug this it can be interesting to look at earlier logcat stack trace 
to see where it really fails.

[android-developers] OnDragListener ACTION_DRAG_LOCATION called only a few times

[Frank]

I implemented an 'OnDragListener' and notice that 
'DragEvent.ACTION_DRAG_LOCATION' is called only a few times (2-4) when I 
drag my shadow around on top of a view (a view with this listener). After 
that, it keeps silent until I release my dragged item. 

The other 'DragEvents' (enter, drop, exited) I do receive as often as I 
expect them. But entered and exited are very slow. I get these events 
500-1000 ms after entering/exiting a view).

So:

 1. The drag listener is slow (the events arrive late)

 2. 'DragEvent.ACTION_DRAG_LOCATION' is called only a few times per
gesture.

Is this normal behaviour?

[android-developers] android drag and drop gridview ordering using OnDragListener

[Frank]

I created a drag and drop gridview (using an 'OnDragListener'). Grid items 
can be dropped upon one another. However, I also want to be able to 
re-order them. I implemented this, but there is a major issue left standing:

When I drag around my shadow object I want the items to make space for my 
dragged object while I am dragging it around. I already implemented the 
moving of the other items, but I cannot seem to figure out a way to find 
out IF/WHEN I am in between two items. I get drag events when I hoover 
ABOVE an item, but not in between then. The gridview does not get any 
'onTouchEvent' calls when I am dragging, not even 'onInterceptTouchEvent' 
calls.

Does anyone know a way in which I can implement this? 

I already tried:

1. Implementing 'onTouchEvent' and 'onInterceptTouchEvent' in the gridview. 
Problem: 
The gridview does not get any 'onTouchEvent' calls when I am dragging an 
item, not even 'onInterceptTouchEvent' calls.

2. Setting another 'draglistener' on the whole gridview. Problem: 
'ACTION_DRAG_LOCATION' gets only called a few times, not on every move 
(location change), as is documented (!!).

[android-developers] OpenGL ES 3.0 support on Android - timeframe?

[Henrik Rydgård]

Hi,

The OpenGL ES 3.0 specification was released this 
summer: http://www.khronos.org/opengles/

Does anyone know when we can expect to see it supported on Android?

Several newer mobile GPUs have the feature set required, and it would be 
nice to be able to access it.

Thanks,
Henrik

[android-developers] Re: How to delete app in new console

[Grzegorz Patynek]

in dungeons app data is stored in sqlite database. 
in order to get a fresh app, you have to increase version of database, then 
dungeons should work fine. 
If you want to delete app, you can do this in app manager and it uninstalls 
completely.
