[android-developers] Android native process pauses after 10 to 15 seconds

[Put_tiMe]

[I'm not sure if I have to ask this question in the NDK forum]

I have an Android Java app, and also a native app. The native app is 
launched from the Java app, like this:

mProcess = Runtime.getRuntime().exec(cmdLaunch, null, new File(files_dir));

The native process actually runs in a loop, and sleeps once in a while to 
yield.

Here's what is happening. After the native process is launched, it runs for 
about 10 to 15 seconds. After that it just pauses. The Java app is still in 
the foreground. I know this from the logcat logs. There is nothing that'll 
make it resume.

Because I'm developing it, I start a new debugging session. This kills the 
previous Java app, and starts a new one.

Now the native process, which was paused, resumes and continues running as 
expected. Now this runs indefinitely without pausing.

What is happening here?

When the parent process (Java app) was killed, should the child process 
(native app) also have been killed? And how come as soon as the parent 
process was killed, the native process started to run without any issues.

Re: [android-developers] Release notes and official info.

[Put_tiMe]

Thanks for your inputs. I went through them, and there is a lot of 
information, but I did not find the ones I was looking for.

I'm specifically looking at: 
Post 4.1, we get logcat logs only from our process  andWRITE_APN_SETTINGS  
permission has been elevated to system level permission.

[Put_tiMe]

Where can I find some official information, like: POST 4.1, we get logcat 
logs only from our process  andWRITE_APN_SETTINGS  permission has been 
elevated to system level permission.

I tried looking, but didn't find any. All I found were forum posts.

[android-developers] How to launch a process as a different user?

[Put_tiMe]

I want to launch a native process, from Java code, using 
RuntimeInstance.exec. But the problem is, the new native process gets 
launched under user "me".

I want the new process to run as user "shell".

How do I do it?

[android-developers] Re: Nexus 7, onCreate is getting called multiple times.

[Put_tiMe]

Aaargh, it was this option that was doing this: *Developer Options -> Don't 
keep activities.*

Switched it off, and it's all fine now.

[android-developers] Re: Nexus 7, onCreate is getting called multiple times.

[Put_tiMe]

Actually when "A" calls "B", "A"'s onDestroy is immediately called.

And I *don't* have the FLAG_ACTIVITY_NO_HISTORY set.

[android-developers] Nexus 7, onCreate is getting called multiple times.

[Put_tiMe]

Nexus 7 - Jelly Bean

I have an activity A.

The usual callbacks are called: onCreate, onResume, etc.

Now I launch B, from A.

Again the  usual callbacks are called, this time for "B": onCreate, 
onResume, etc. 

I close "B". Now "A"'s onResume should get called.
But onCreate is getting called.


This issue is only on the Nexus 7 tablet, and not on Motorola XOOM, running 
Jelly Bean.

How do I fix this?

[android-developers] Activity stack question (another one, I'm afraid) SDK 8

[Put_tiMe]

I'm using Android SDK 2.2.

Activity stack -> A -> B -> C -> D -> E

Now I press "Home" key.
And I press the notification area to goto "A" again.

Because of the stack issue, I make sure that I close "B", "C", "D" and "E", 
using the static "Instance".
Now, the new activity stack::
A -> B -> C

Now when I'm at "C", "E"  appears in front of it.
How is it possible, cause I had closed "C" and "D" earlier?

[android-developers] Multiple e-mail attachments of arbitrary files.

[Put_tiMe]

Surprisingly, this topic seems to be still in it's infancy. There are very 
few posts, and those who have given it a shot have given up since it didn't 
work.

I need to attach multiple files of different types in a single e-mail. File 
types could be image, audio, video, zip, doc, and so on.
I did give it a shot. 


// List filePaths;

Intent emailIntent = new 
Intent(android.content.Intent.ACTION_SEND_MULTIPLE);

// I tried both the following lines
emailIntent.setType("*/*"); 
emailIntent.setType("vnd.android.cursor.dir/email");

// has to be an ArrayList
ArrayList uris = new ArrayList();
//convert from paths to Android friendly Parcelable Uri's
for (String file : filePaths)
{
 File fileIn = new File(file);
 Uri u = Uri.fromFile(fileIn);
 uris.add(u);
}

emailIntent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, uris);
context.startActivity(Intent.createChooser(emailIntent, "blah blah"));


Overall, it looks like it's working. The 'createChooser' gives me a list of 
available e-mail apps.
 If I choose "GMail" app from the list, in the 'compose' activity, I can 
see the attachments also. I then hit 'send'.
But when I receive the mail, I find no attachments.

If I see the "sent" folders of Gmail, this email doesn't have attachments.

So what do I need to do?

[android-developers] ListView and check box.

[Put_tiMe]

I'm using a list view with a custom adapter. And the row contains a check 
box.

Without the check box, everything works fine.
If I use a check box inside a list-view row, then I basically don't get a 
on-item-click callback.
The other side effect is, the "click" or "press" visual feedback is also 
not shown.


For the callback, in the "getView" of the adapter, I can register for a 
callback for the "row". Like this:
row.setOnClickListener(mOnItemClickListener);

But I couldn't figure out any way of getting the visual feedback to work.
Is there anyway I can get the visual feedback to work?

[android-developers] Play Store kind of UI interface

[Put_tiMe]

(I'm using 2.2 SDK)

Play store app has a UI in which you can scroll vertically to look for 
content in the current category.
If you want another category, you can swipe left or right. There is also a 
smooth transition into the resulting category.

Is this UI control/view already available in native SDK, or is it something 
that is built into the app?

I've seen similar UI in "ES File Explorer".

[android-developers] How to unlock device programmatically and launch apps?

[Put_tiMe]

I want to run a few tests on the device. The device should *NOT* be 
connected through USB. i.e. no ADB.
So basically my app/service should be stand alone.
And this app is purely for internal purpose. So even a horrible hack that 
works consistently well is fine.


Let's say I want this app/service to wake up (probably using alarm manager) 
every N minutes and do the following:


   - Turn the display on
   - Unlock the device
   - launch youtube app (and play a video)
   - Since youtube app holds a display lock, the screen won't go off as 
   long as the video is playing.
   - Once the video has finished playing,  youtube app itself releases the 
   display lock, and hence the screen should go off on it's own.


Now how do I do this? Do I use a test framework? The most important thing 
here is that I *don't* want to use ADB.


Looks like testing tools, like MonkeyRunner, work only on ADB.

I tried using AlarmManager, with the "RTC_WAKEUP", and the PowerManager 
"wake lock". But it's too inconsistent.

Re: [android-developers] Fails to delete row from "content://call_log/calls"

[Put_tiMe]

Ok, here's the issue. On some devices, the "sms" entries are also listed 
under  "content://call_log/calls". 
I don't know why. And they don't get deleted, if I call delete (which is 
good).
Is there anyway I can differentiate between a call and an SMS?

I have a ListView, and a custom adapter.
I have setup listeners for click, and long-click.

[android-developers] A very strange issue, while launching an activity.

[Put_tiMe]

I have two activities, "A" and "B".
By default, "A" shows up, and upon pressing a button, "B" is shown.

What happens sometimes is that, in "A", when I press the button to bring up 
"B", the transition happens, I even see the "B's title".
But it immediately exits.

I don't do any code changes. I just reinstall the APK file, by using *adb 
install -r "c:\ABC.apk"*.

And it works. 
I've connected to logcat, but no messages there also.

What could be happening?

Re: [android-developers] Can I have a service run as a seperate process?

[Put_tiMe]

Hmm, this is surprising. If I give my service another name, then I can't 
pass commands to it by calling 'setAction'.
i.e. my service never invokes "startCommand".

Any reason why?
Or any other work around for this?
i.e. I don't want to do IPC.

Re: [android-developers] Can I have a service run as a seperate process?

[Put_tiMe]

There are two services. Out of them one is a work horse. While the other 
one is not.
And the work horse service is something that the user chooses to turn on or 
off.

If on, then when I see battery usage, my whole package comes up on top.
I don't want that. If the work horse service is running, then I want to 
show it as that, not the entire package.

[android-developers] Can I have a service run as a seperate process?

[Put_tiMe]

I have a package, in which I have "n" activities and "2" services.

Out of the two services, I want one service to run as part of the package, 
whereas the other service, I want to run as part of a different process.
Is this possible?

[android-developers] Which is better, one trigger receiver and multiple services -- or -- one trigger receiver per service.

[Put_tiMe]

I have a situation where in I need to have 5 or more services running in 
the same package.
Let's call it service "A", "B", "C", "D" and "E"

Which is a better way of doing this? Better in terms of memory and CPU 
usage (and hence battery usage and efficiency).

1. Have 1 main service running, apart from the 5 mentioned above.
Have only one trigger receiver and a the main service is linked with 
this trigger receiver.
This will listen to all intents that are required.
When an intent goes off, then we check if "A" needs this intent. If it 
needs, then we call startService("A", intent);
Same with the other 4 services.

2. Have 1 trigger receiver linked with each of the 5 services.
Handle intents 1 on 1 basis.

Re: [android-developers] How to create an ongoing notification, without the icon in the top bar.

I kind of figured that out, it shows a blank icon. But the draw back is it 
still uses up real estate.

Is there no way we can knock off our icon from the bar, but still have the

[android-developers] Service not re-starting on time, on a Samsung Galaxy Note device.

[Put_tiMe]

I am running my service on a Galaxy Note device. When I switch off the 
screen, and after a while (2 mins) switch it on and go to :: Settings -> 
Applications -> Running Services::

then I see that there are lots of services that have the "Restarting" tag.
For my service, it restarts after a very long time. And sometimes it 
doesn't restart even after 5 minutes. I have the "restarting" tag 
continuously.

Is there any way I can restart my service as soon as the screen is switched 
on.

BTW, I have registered for Screen-on intent.

If I launch my activity, which in turn starts my service, I immediately see 
that the service has started.

How do I sort this out?

Nothing actually, here's my gallery definition.

[android-developers] Activity stack.

I have an activity that launches another activity, like let's say

Let's say facebook app was already running, and you were in "what's on your

When my app launches the facebook's  "post to wall" activity, and in that 
activity I press 'Back", then the facebbok's  "what's on your mind" 
activity is now on top of stack.

But I want my activity to be on top. What should I do?

I'm using the following flags while I'm launching   facebook's  "post to 
wall" activity.

Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET 
| 
 Intent.FLAG_ACTIVITY_PREVIOUS_IS_TOP |

The idea is the "embed" the activity inside my tab-view.

[android-developers] Sub folders under 'layout'

[Put_tiMe]

The number of XML's in my layout folder is growing and is becoming 
difficult to manage.

So I want to create sub folders, under layout, to better manage this.

Is there any way the resource compiler can handle this?

So instead of *R.layout.layout_a* I want to refer it as  *
R.layout.folder_1.folder_x.layout_a*.

Re: [android-developers] Re: Directly accessing the e-mail app.

[Put_tiMe]

I'm looking at this: if *com.android.email* package exists, then I want to 
open the "compose" activity, and automatically fill up the fields, such as 
'to', 'subject', etc...

If the default mail package doesn't exist, then I don't mind showing the 
chooser.

The reason I want to do this is:
I know I want to send an e-mail. I don't want the user to choose 
'bluetooth'.
Because I know I don't want to use the 'bluetooth'.

I need to do at least this: the chooser should should only the e-mail 
capable apps. is that possible?

[android-developers] Directly accessing the e-mail app.

[Put_tiMe]

How do I directly choose the default e-mail app, without going through the 
chooser?

I would also like to set some of the values through the intent, like:

emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL, recipients);
emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "blah");
emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, "Wow! direct email 
works");
emailIntent.setType("text/plain");


Is there any way I can do it, without going through the chooser?

Re: [android-developers] List view row background.

[Put_tiMe]

Ok, I kind of got it together.
 
For the row, I'm setting the background to my bitmap image.
For selection, I'm setting the ListView attribute:
android:listSelector="@drawable/xxx"
 
 
It kind of works. But I can't see the selection.
i.e. when a row is selected (or clicked) I don't see the color change.
This happens when I set the background for the rows.
 
To counter that I tried setting this attr: android:drawSelectorOnTop="true"
 
But the problem with that is that the row contents are completely hidden.
 
What should I do in this case?

Re: [android-developers] Relative layout : how to horizontally center align 2 children.

[Put_tiMe]

My layout is a little bit complex. 
I think centerHorizontal centers it w.r.t the parent.
 
But my UI elements parent is the layout itself.
And I did try "centerHorizontal" on the 2 UI child elements that I want to 
center align, and it didn't work.
 
Maybe because those controls already have a horizontal-align flag set???

[android-developers] Re: ScrollView and programmatically scrolling

[Put_tiMe]

It's actually quite crazy.
 
I had similar problems with scroll view.
 
But from what you are saying, you are interested in scrolling the text-view.
I would presume that the text-view has scroll-view bundled in it.
 
If things are not working out, then try this (at least this is what I did):
Derive scrollview and write your own class. Override scrollTo and other 
similar function with which you have control over scrolling.

Re: [android-developers] Difference between user-induced "screen on" and programmatically induced "screen on".

[Put_tiMe]

I have registered for SCREEN_ON intent.
 
In the alarm-manager, I grab a wake_lock with 

*FULL_WAKE_LOCK* flag and that switches on the screen.
 
This sends a SCREEN_ON intent.
 
In the meanwhile, the user could also have switched on the screen.
 
I want to handle this intent in different ways, depending on where it 
originated from.

[android-developers] Difference between user-induced "screen on" and programmatically induced "screen on".

[Put_tiMe]

Screen-on can be done in two ways:
 
1. User pressing the power (or home button)
2. Through code: by using power manager -> wake lock -> with screen-on flag.
 
Either ways, I get a 'Intent.ACTION_SCREEN_ON' intent.
Is there anyway I can distinguish between the two intents?

[android-developers] Re: Sleep mode

[Put_tiMe]

Sorry, I missed Dianne's post above.
 
So according to Dianne's post, CPU is indeed completely switched off.
And in Android, there is no CPU under clock mode.
And it can be woken up only by external interrupts. Got that.
 
But then how does Alarm-manager timers work?
Is it some kind of delayed interrupt or something like that? i.e an 
interrupt that will be raised after some time???
I thought at least the alarm-manager will need the CPU running.

[android-developers] Re: Sleep mode

Ok, to clear some confusion, does CPU off means that CPU is completely

If CPU is completely off, then how does the AlarmManager even work, and how 
does the phone receive an incoming call or an SMS?
 
I'm sure CPU will be required to run some basic OS services, right? Like 
the phone and SMS, and the alarm-manager itself.

During that alarm-manager handler, if I acquire a wifi-lock and a 
wakeup-lock.
 
Still, if I enable/disable wifi programmatically, it doesn't work.
 
But the moment I switch on the screen manually, it works fine.
Any ideas why?

[android-developers] PowerManager WakeLock is inconsistent.

[Put_tiMe]

On an AlarmManager intent, I am trying to switch on the device screen. And 
I am relying on the system to switch off the screen after some duration of 
no user activity.
 
I use:  PowerManager.XXX| PowerManager.ON_AFTER_RELEASE | 
PowerManager.ACQUIRE_CAUSES_WAKEUP

flags.

PowerManager.XXX is either 
*SCREEN_DIM_WAKE_LOCK*
 or 
*FULL_WAKE_LOCK*
.

 

Screen does indeed come on in the 
*FULL_WAKE_LOCK*.
 
But each time, and on different devices, the duration it stays on is very 
inconsistent.

Example, sometimes it's 1 second, whereas sometimes it's 25 seconds.

Why is this? Is there anyway I can make it consistent?

 

If I use 
*SCREEN_DIM_WAKE_LOCK*
 flag, 
then on each device the behaviour is different. Like on some devices, the 
screen never comes on, but on some devices, it comes on and is dimmed.

[android-developers] Wake-lock instance.

[Put_tiMe]

The PowerManager.newWakeLock() will return a new instance of a wake 
lock every time.
 
If I have an intent service or an alarm manager service, then I won't have 
an "instance" to store this wake lock.
 
Whereas I want to work on one instance of the wake-lock object.
 
How do I handle this situation in an intent-service or an alarm manager 
service?

Re: [android-developers] Sleep mode

[Put_tiMe]

On some devices, like the Sony Erricson Experia, if I long press the power 
button, I get a UI menu, with a sleep mode option.
 
What would be the difference between that sleep mode and the screen-off 
sleep mode?
 
 
On screen-off, i.e. when it hits the sleep mode, are the wifi radios and 
CPU disabled/switched-off?

[android-developers] Re: Wifi lock question

[Put_tiMe]

Another question, if a particular app has acquired the wifi-lock.
Another app goes and switches off the wifi.
 
What happens now?
Will the wifi-lock prevent the wifi from switching it off?
Or is the wifi lock ignored, and the wifi radio is still switched off.

[android-developers] Wifi lock question

[Put_tiMe]

I want to know if I can do this:
 
I have two alarm managers, to trigger once every X minutes.
 
Alarm A: every 10 minutes
Alarm B: every 12 minutes.
 
I start both of them at once. So "A" should hit every 10 mins, and "B" 
should hit every 12 mins.
 
Now in "A", I create a wifi lock, and acquire it.
Because intents raised by alarm-manager won't have a concept of instance, I 
can't save this wifi-lock object anywhere.
 
In "B", How can I use the same wifi lock object to release the wifi lock?
 
Is it possible?

2. I switch off the screen, and the phone goes to sleep in a few minutes.
3. After 15 mins, the alarm manager kicks in.

[android-developers] Wifi and phone sleep state

[Put_tiMe]

I have a situation where in I use AlarmManager to wake up once in a few 
minutes, and switch on/off wifi.
If I don't use the device for a while, then the wifi never connects to the 
preferred wifi network.
Is there anything happening with the wifi if the phone is in a sleep state?
 
And how exactly does the phone reach the "sleep" state?
 
In a sleep state, will the phone not connect to wifi?

[android-developers] Sizing a custom 'GridView'.

[Put_tiMe]

I have a situation where I need to have a GridView on the top part and 
buttons below it.
 
If it was the other way around, then, it would have been easy. i.e. buttons 
on top and gridview below it.
For the gridview, I could have mentioned:
 
android:layout_width="wrap_content"
android:layout_height="wrap_content"
 
and it would have worked just fine.
 
 
But I got to have the buttons below the grid view.
So now, how do I size the grid view? Can I mention it in screen height 
percentage?
 
Cause if I use "wrap_content", then the gridview takes up the entire screen 
and the buttons are not visible.
 
And I want it to look even on all screen sizes.

[android-developers] Re: Broadcast receiver execution.

[Put_tiMe]

Hmm, that is actually quite surprising to me. Especially if I want to do 
something on screen-on and off.
 
So in the above case, if I get the intents in this order Off, On, On, Off   
instead of the right sequence Off, On, Off, On, then all my logic will go 
horribly wrong.
 
 
Are you sure about the system intents being delivered not in the sequence 
they were generated?

[android-developers] Wifi manager woes

[Put_tiMe]

Based on some events, I'm trying to switch on or off wifi.
 
 
Switching wifi off works well. But while switching on wifi, 95% of the 
time, it can't reconnect to my previous wifi network.
If I goto the settings -> wifi, then I see that it's trying to connect, and 
after a while it'll disconnect.
But wifi service is on.
 
Sometimes 'reconnect' call returns false.
 
 
I went to the extent of waiting until the wifi service is switched on, 
before reconnecting.
 
Any idea as to how I can reconnect to my previous (or any) wifi network.
 
 
onEvent_SwitchOn()
{
 WifiManager wifiManager = 
(WifiManager)context.getSystemService(Context.WIFI_SERVICE);
android.text.format.Time cTime = new android.text.format.Time();
 android.text.format.Time nTime = new android.text.format.Time();
   
 if(!wifiManager.setWifiEnabled(true)) {
  Log.e("Err", "setWifiEnabled - true, failed");
 }
 
// wait for about 5 seconds until wifi service is actually switched on
cTime.setToNow();
 nTime.setToNow();
 while(true)
 {
  long diff = nTime.toMillis(true) - cTime.toMillis(true);
  if(diff > 5000)
  {
   break;
  }
  int  state = wifiManager.getWifiState();
  
  if(wifiManager.WIFI_STATE_ENABLED == state)
  {
   break;
  }
  
  try {
   Thread.currentThread().sleep(100);
  } catch (InterruptedException e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
  }
  
  nTime.setToNow(); // update to the latest time
 }
 

if(!wifiManager.reconnect()) {
  Log.e("Err", "Wifi manager (reconnect) failed");
 }

}
 
}

[android-developers] Broadcast receiver execution.

[Put_tiMe]

I have a class which is derived from 'BroadcastReceiver'.
Here I've signed up for screen-off, screen-on, battery-changed and 
user-present intents.
 
I want to know how my class receives messages.
 
Are they received in the order they were raised?
 
Or is there a chance that messages could arrive out of order.
 
Ex. assume the screen was on. Now I switch it off, and immediately switch 
it back on. Then I switch it off immediately. Then I switch it on 
immediately.
I'm talking about this whole sequence of events happening in less than a 
second.
 
In this case will I be receiving the messages in this order:
1. Off
2. On
3. Off
4. On
 
 
Is there any chance they can be out of order?
 
 
Thanks

[android-developers] How is 'onHandleIntent' handled in an IntentService

[Put_tiMe]

I have an intent service.
>From another class, I create 3 different intents at 3 different times, like 
this:
 
At Time X:
Intent aIntent = new Intent(context, abcd.service.ABCD_Processor.class);
aIntent.setAction("Do_A");
context.startService(aIntent);
 
At Time X + 50 milliseconds:
Intent bIntent = new Intent(context, abcd.service.ABCD_Processor.class);
bIntent.setAction("Do_B");
context.startService(bIntent);
 
At Time X + 100 milliseconds:
Intent cIntent = new Intent(context, abcd.service.ABCD_Processor.class);
cIntent.setAction("Do_C");
context.startService(cIntent);
 

 
In the *abcd.service.ABCD_Processor* class, the 
protected void *onHandleIntent*(Intent intent)
 
function will be called 3 times.
 
I want to know how the onHandleIntent callback will be invoked?
 
Will they be invoked one after the other, in the order they were raised.
Is there any chance that 'onHandleIntent' will be called in parallel, to 
handle more than one intent simultaneously.
 
 
Thanks

My problem is that I'm not able to place the image on the extreme RHS.
 
 
My XML file for the row looks like this:
 





 

 
how can I fix this issue? How can I place the image to the extreme RHS of 
the list view row.

[android-developers] Handling different icon dimensions from Apps.

[Put_tiMe]

I have a requirement wherein I have to enumerate all the installed apps and 
show their names along with their icons.
 
I'm using a grid view for this.
 
Inside the grid view, I have an imageview for showing the app's icon and a 
textview to show the app name.
I have a problem, in the sense every app has got different icon dimensions.
So some icons appear huge, whereas others appear normal.
 
How do I ensure that all icons are of the same width and height?
 
I'm using the following properties for ImageView:

<

ImageView android:id=*"@+id/icon"*

android:layout_width=*"75.0dip"*

android:layout_height=*"75.0dip"*
* *

android:maxWidth=*"75.0dip"*

android:maxHeight=*"75.0dip"*

android:width=*"75.0dip"*
* *

android:height=*"75.0dip"*

android:scaleType=*"centerInside"*

android:adjustViewBounds=*"true"*

android:paddingLeft=*"5dp"*

android:paddingTop=*"0dp"*

android:paddingRight=*"10dp"*

android:paddingBottom=*"10dp"*

android:gravity=*"left"*

android:src=*"@drawable/defaulticon"*/>

[android-developers] Check box inside of a GridView

[Put_tiMe]

I have a gridview, inside which I have a check-box and imageview and 
textview.
 
I need to use the check box to determine whether a particular row is 
selected or not.
 
All the other controls work as expected, except for the check-box.
When I toggle the check box, the corresponding checkboxes in the other 
pages also get toggled.
 
For example, I see 4 rows in one view (i.e. page).
When I select the 1st row check box, then the 5th, 9th, 13th, 17th, etc 
rows are also selected.
 
How can I correct this. I want each row's check box to be independent.
 
 
The contents of the row is coming in from a XML file, and I refer like 
this:  
 

public View getView(*int* position, View convertView, ViewGroup parent)
{
  CheckBox  cbox;
 
 
  cbox = convertView.findViewByID(R.id.checkBoxID);
 
}

[android-developers] Extending ScrollView

[Put_tiMe]

I might have to extend ScrollView and I would like to call it *myScrollView*
.
Is it possible to specify this *myScrollView* in the XML file itself?
Or can it be done only programmatically?
 
 
If it can be done only through code, then, can I squeeze in a layout 
specified in the XML file into *myScrollView?*
So that *myScrollView* becomes the parent.

[android-developers] Problems with scroll view and orientation

[Put_tiMe]

I have a ScrollView. If the orientation is changed, then it's scroll 
position is automatically changing.
 
Is there any way to switch off automatic scrolling?
 
If I use any other view, like LinearLayout, then it works fine (except 
there is no manual scrolling also)

Re: [android-developers] Background and foreground image views

[Put_tiMe]

Ok, I tried the frame layout.
 
And my XML file is something like this:
 
http://schemas.android.com/apk/res/android";
android:layout_width="fill_parent"
android:layout_height="fill_parent" >

 
 
 
 



 
 
Now it did work on my phone.
But it still doesn't behave well on my 7" tablet.
 
My first problem is that it doesn't fill the entire screen. Why is that?
I have mentioned "fill_parent" for the frame layout.

[android-developers] Re: Scroll position is not the same when orientation changes.

[Put_tiMe]

I think I have a hint as to what is going on.
 
Basically my first focussable item is not right on top.
So when the layout changes, the current focussable item is brought into 
view. During this calculation, the scroll is set.
That is why my top portion of the layout is scrolled out.
 
How do I prevent this?

[android-developers] Scroll position is not the same when orientation changes.

[Put_tiMe]

I have a scroll view activity under which I have lot's of UI objects.
 
Now let's say when the activity starts up, the view is right on top.
 
Now if I change the orientation of the phone, I observe that my activity 
has automatically scrolled to a different position.
I don't want the scroll position to change, i.e. I want to see 
approximately the same content.
 
I tried fixing it by saving the scroll position in the 
'onSaveInstanceState' and then restoring it in 'onCreate'.
But didn't work.
 
How do I fix this?

[android-developers] Getting access to the cluster level data of an micro SD card.

[Put_tiMe]

In Android, is it possible to get access to the cluster level data of a 
micro SD card?
 
Like in Win32, you would do a CreateFile("\\.\\d:", );
or CreateFile("physicaldrive0\ ", );
 
That way I should be able to access the boot sector.
 
Does Android support SD cards with FAT file system only?
Or are there any more that are supported?
 
Thanks

[android-developers] Passing parameter in intent.

[Put_tiMe]

I'm trying to send a parameter to an activity. But the problem is that in 
the activity's 'onCreate' callback, the 'Bundle' parameter is always null.
 
 
 

Intent aintent = *new* Intent(android.content.Intent.*ACTION_VIEW*);
*try
*{

aintent = new Intent(getApplicationContext(), AAA.*class);*
aintent.putExtra(Intent.*EXTRA_TEXT*, *"whatever"*);

startActivity(aintent);

}

 

@Override

*public* *void* onCreate(Bundle savedInstanceState) {

'savedInstanceState' is always null
 
}

Ok, I got it to work.
I HAD to add a scroll view to the text view.

 android:layout_width="fill_parent"
 android:layout_height="fill_parent"
 android:orientation="vertical"
 android:isScrollContainer="true"

 android:scrollbarStyle="outsideOverlay" >
 

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:inputType="text|textMultiLine"
android:scrollHorizontally="false"

 
And for the word wrap to work, see the attributes for TextView above.

Re: [android-developers] Battery manager : temperature and voltage

[Put_tiMe]

Ok, by derived, I mean can I find out how long the battery will last?
This is because battery lasts longer at ideal temperature, 
 
Or if the voltage is not within a threshold, then does it mean anything?
If the voltage is high, then does it mean more power is being consumed, and 
thus the battery will not last as long as it should.

[android-developers] TextView scroll in an activity.

[Put_tiMe]

I have a main activity. Based on a button press, I have to launch a 'new' 
activity.
This 'new' activity has just one UI item, i.e a TextView.
I've added properties which will indicate that it is scrollable: *
android:scrollbars*
 (vertical), 
*android:scrollHorizontally*
 (true), 
android:layout_width="wrap_content"
android:layout_height="wrap_content"
 
The 'new' activity is started like this: 
getApplicationContext().startActivity(this, MyNewActivity.class);
 
The 'new' activity shows up fine, but my only issue is that the text view 
is not scrollable. There is enough content for the TextView to scroll.
I want to get it to scroll vertically.
 
 
Is there anything I'm missing?
 
 
 
Sub questions: 
And how do I enable word-wrap on a TextView?
How do I know if an activity has already started/running?
 
 
Thanks
