[android-developers] Doubt Layout

[Diego N.]

Hello,

I would put two buttons on one line, so that they occupy the entire
horizontal space as possible with equal sizes.

I put these buttons in a grid layout, divided into two columns.

There is some property of the layout that can do this?

[android-developers] Doubt on setOnKeyListener

[Bins]

I've created 2layouts 'l1', 'l2'.
Included an EditText view 't1' in layout 'l1'.
I've set keyListener for 't1'.

KeyListener is working fine when the activity is invoked and 'l1' is
displayed first.
My problem is that when i navigate to 'l2' and come back to 'l1', the
keyListener for 'l1' stops working anymore.
What's the solution for this problem? How do i get the KeyListener to
work everytime i navigate to 'l1'?

have several of doubts regarding the application.
1. What is the exact purpose of Intent class?

startActivityForResult(i, ACTIVITY_CREATE); method.
3. What happens at the end of startActivityForResult(i,
ACTIVITY_CREATE); method, which method is getting called after that?
4. What is the purpose of  onActivityResult(int requestCode, int
resultCode,
   Intent intent) method??

Any explanation would be highly appreciated

[android-developers] Doubt about heap size

[Francisco M. Marzoa Alonso]

Hi there,

I have read that the maximum heap available for an app is 16M, despite
that there may be higher on newer devices.

Anyway on a 2.1 emulator with Eclipse/DDMS my available heap shown is
just about 3M, while in  my SGS2 real device shows about 5M of available
heap. As you see, a lot of lower than 16M.

My app runs fine on my SGS2, but it crashes complaining about not having
sufficient heap memory on the emulator, and I have received a few
reports with the same error on Google Play.

I am currently doing an effort to decrease heap consumption, but I
wonder why DDMS shows values so low and if some devices may actually
have less than 16M of heap memory.

My app is developed for Android 2.1+

Best regards,

The solution is to make sure you key listener is set, even when navigating
away from your Activity.
Considering you posted almost no information, that's the best I have for
you.

Consider posting a code snippet of where and how you set this listener if
you want some real help.

[android-developers] doubt in xmlns:android tag

[Sohan badaya]

Hi All,

In android xml files we define xmlns:android="http://
schemas.android.com/apk/res/android" in root tag, so then we use
android:attributes.  I want to know what is the location where these
attributes are defined. and if we want can we define our custom
attributes.

thanks,
sohan

Re: [android-developers] Doubt w.r.t content resolver

[Rui Wu]

All member functions in AppWidgetProvider have a Context type. I think you
can call Context's getContentResolver() to get an content resolver intance.

[android-developers] Doubt logcat log - program blocked

[David Muñoz]

Hi everybody!

This is my first message since I've just joined your mail list. So first of
all hi to everybody.

I am now developing for android and having some issues so I will directly
publish the problem:

I have developed one application which uses the bluetooth and transfers data
through a 3g connection. The problem is that, sometimes the application just
freezes for a while(maybe half an hour, one hour or just "forever"). I
connected the application to the computer and taken the log from logcat. the
moment where the phone seems to be blocked is here:



D/QCRIL_MSC (   73): "RIL"=>"AMSS" [ label = "cm_ph_cmd_get_ph_info()"];

It seems that the E/Sensors(133) referes to the bluetooth that seem to be
"away" for a while and that sending the information it launches a
SocketTimeoutException, but I am checking before sending any data that the
NetworkInfos have some wifi/mobile connection available.

Additionally, the phone sometimes just reboots alone(the program is running
for hours) and stays in the "PIN" request state.

Thank you in advance!

It seems that the E/Sensors(133) referes to the bluetooth that seem to
be "away" for a while and that sending the information it launches a
SocketTimeoutException, but I am checking before sending any data that
the NetworkInfos have some wifi/mobile connection available.

Additionally, the phone sometimes just reboots alone(the program is
running for hours) and stays in the "PIN" request state.

Thank you in advance!

[android-developers] Doubt about RingtoneManager and Soundpool class

[ankita.nhst]

Hi,

I wanted to understand that is there any method through which
Soundpool could communicate with the RingtoneManager class as
MediaPlayer can pass the reference of the songs from its storage place
to the ringtone list but, there is no well-documented method that is
doing it. (at least i have not encountered it so far after googling
for a while).

So, my query is do I need to dig deep into the code to understand it?
if so, kindly suggest me what possible areas to look into as I have
already seen MediaPlayer-related classes a bit but, in the end I got
lost into the maze.

And, if not so i.e. its documented, then kindly direct me to the
appropriate link.

TIA.

Regards,
Ankita

[android-developers] doubt in accessing database in /data folder

[Kruthika Shastry]

hi

i want to develop an app for synchronizing notes between an android app in
my android mobile and my PC. I want this app to be accessible for other
android users also. I am using android 2.3.6 and my mobile is samsung
galaxy ace. The IDE is eclipse and OS is windows 7.

i have rooted my phone. When i try to access  the database of this app
which is stored in /data/data/app_package_name/databases/app_database_name,
I get an error "Could not create or open database". I don't understand why
this is happening. I am able to access the same database from adb shell in
command prompt but when i want to access via eclipse it doesn't seem to
work. Also, I am not able to see the list of sub-folders of /data folder in
the file explorer of eclipse.

I even changed the access rights of /data/ folder and the relevant sub
folders but..alas..my phone crashed after that! So after recovering my
data, I changed the access rights of only the app_database to read-only.

Any help would be greatly appreciated!

Regards
Kruthika

[android-developers] Doubt regarding redirection of websites to mobile version and address bar of browser.

[sat]

Hi

1.

I am launching the browser in a normal way with URL supplied as
parameter,

Intent ln_intent = new Intent(Intent.ACTION_VIEW);
ln_intent.setDataAndType(Uri.parse(web_url), "text/html");
startActivity(ln_intent);

here web_url is any web url.

This opens the browser with the mobile version of the
url(website) ,i.e. from the normal version it gets redirected to
mobile version.

Problem is when I press back address bar shows url of normal version
of the website but the page is blank , How can I overcome this problem.
(i.e. back should directly take me to last activity avoiding showing
the blank page)

2.
Is there any flag by which I can tell the browser to hide the address
bar ? (without using webview)
