[android-developers] Re: [Applications signed by manufacturer/Permissions not granted] Correct approach to develop appliations for device manufacturers

2011-11-29 Thread cpphool

Hi!

Thank you for your response!

Ok, I understand that it would be quite a difficult task and I should
get familiar with Android source code in the first place.

Just say no.

First of all, there are a lot of Android permissions that are not
granted to 3rd party apps unless they are signed with manufacturer
certificate, f.e. android.permission.READ_FRAME_BUFFER.

http://developer.android.com/reference/android/Manifest.permission.ht...

Android documentation says: Allows an application to take screen
shots and more generally get access to the frame buffer data. Ok, so
how can I take this screen shot? Is there some API?

No.

Or should I
directly access framebuffer (like many applications that work on
rooted devices do)?

Your guess is as good as mine.

1) Where can I find out how these permissions exactly work?

Read through the source code onhttp://source.android.com. Searching
on the name of the permission frequently comes up with interesting
stuff.

2) Should not there be some information if permissions are accessible
by normal 3rd party applications or not?

There isn't in the documentation.

However, in frameworks/base/core/res/AndroidManifest.xml in the source
code, you will see declarations like:

!-- Allows an application to take screen shots and more generally
get access to the frame buffer data --
permission android:name=android.permission.READ_FRAME_BUFFER
android:label=@string/permlab_readFrameBuffer
android:description=@string/permdesc_readFrameBuffer
android:protectionLevel=signature /

The android:protectionLevel tells you what is required. In this case,
signature means that it must be signed with the same signing key as
is used with the firmware. You will also sometimes see
signatureOrSystem, which (from what I can tell) allows both
signature-based apps and ones that reside in /system/app.

3) Secondly, is there a way of testing an applications that uses these
non-public permissions? I assume that you would have rooted device in
order to do so. But can you switch something in the rooted Android
operating system so that it would grant all permissions for all
applications?

Not that I am aware of, but that's a far better question for some
firmware-related Google Group, hosted over onhttp://source.android.com.

[android-developers] [Applications signed by manufacturer/Permissions not granted] Correct approach to develop appliations for device manufacturers

2011-11-28 Thread cpphool

Hi!

I was wondering what is the correct approach when developing
applications with non-public functionality for Android device
manufacturers.

First of all, there are a lot of Android permissions that are not
granted to 3rd party apps unless they are signed with manufacturer
certificate, f.e. android.permission.READ_FRAME_BUFFER.

http://developer.android.com/reference/android/Manifest.permission.html#READ_FRAME_BUFFER

Android documentation says: Allows an application to take screen
shots and more generally get access to the frame buffer data. Ok, so
how can I take this screen shot? Is there some API? Or should I
directly access framebuffer (like many applications that work on
rooted devices do)?

So, to make long story short:

1) Where can I find out how these permissions exactly work?
2) Should not there be some information if permissions are accessible
by normal 3rd party applications or not?

3) Secondly, is there a way of testing an applications that uses these
non-public permissions? I assume that you would have rooted device in
order to do so. But can you switch something in the rooted Android
operating system so that it would grant all permissions for all
applications? I understand that this might be some low level question,
but I wasn't able to find any documentation concerning this subject.

I would be grateful for any reponse!

[android-developers] Cannot always launch DevicePolicyManager activity from another activity

2011-03-04 Thread cpphool

Hi,

I have some strange problem. When I try to launch DevicePolicyManager
activity from my main activity, it loads properly. However, when I
make a notification, call QuestionActivity (if user clicks the
notification), and then try to call DevicePolicyManager activity from
QuestionActivity, I get (logcat):

INFO/ActivityManager(104): Starting activity: Intent
{ act=android.app.action.ADD_DEVICE_ADMIN
cmp=com.android.settings/.DeviceAdminAdd (has extras) }
WARN/InputManagerService(104): Window already focused, ignoring focus
gain of: com.android.internal.view.IInputMethodClient$Stub
$Proxy@4514a2d0

And nothing appears. This is strange for me, cause I'm able to launch
different Android OS activity from QuestionActivity:

//This works
Intent intent = new Intent(Settings.ACTION_BLUETOOTH_SETTINGS);
startActivity(intent);

But I cannot launch the DevicePolicyManager with:

//This works from main activity, but not from QuestionActivity
MyDeviceAdmin admin = new MyDeviceAdmin(this);
Intent intent = new
Intent(DevicePolicyManager.ACTION_ADD_DEVICE_ADMIN);
intent.putExtra(DevicePolicyManager.EXTRA_DEVICE_ADMIN,
 admin.getDeviceAdminComponent());
intent.putExtra(DevicePolicyManager.EXTRA_ADD_EXPLANATION,
Additional text explaining why this needs to be
added.);
startActivityForResult(intent, 234234234);

I would be very grateful for any help, cause I'm completely stuck.

[android-developers] T-Mobile Android Firmware - Pulse device - Data SMS Messages

2010-03-29 Thread cpphool

Hi!

I am developing an Android aplication that receives data messages (it
is different than usual text messages and wap push). I have been
testing it with different platforms and devices (Htc G1, Magic, Hero,
Acer Liquid, Samsung Galaxy). It works on every device but T-Mobile
Pulse.

I am using this intent filter:

intent-filter
action android:name=android.intent.action.DATA_SMS_RECEIVED /
data android:scheme=sms /
data android:host=localhost /
data android:port=3 /
/intent-filter

The problem is that on T-Mobile Pulse these messages apear in the
inbox, but they are not catched by my app. I suppose it is connected
with Pulse firmware. Is there any way I could ask for support from a
team that had developed this firmware?

I would be very grateful for any response!

  Hi!
  I have some questions concerning importing contacts to the device,
  which is extremely slow.
  First of all, if you delete all your contacts, google sync will
  restore it very quickly. However, when my app is adding contacts to
  the device, it's very slow (a few contacts per second). Even if I add
  almost empty contacts (with name only), it is a time-consuming
  process.
  If I turn google sync off, importing 5000 contacts can take 1-2 hours
  (on HTC Magic). When google sync is on it can take up to 24hours. And
  this happens despite the fact, that application for the whole time is
  in the foreground, device is connected to charger and screen is on. I
  checked the logcat to make sure my app is adding the contacts the
  whole time, and it is.
  I tried different methods and different devices. The results differ of
  course, yet manually adding contacts is always significantly slower
  that google sync. Is there any way that I can speed up the process? So
  that importing 5000 contacts will take less than an hour.

Can you give us some example? As I understand, AsynTask is used for
threading. How should I use it to improve speed?

I suppose I could create an AsyncTask with a method doInBackground().
This method would add only one contact at a time. Then, I call execute

there were some changes to the contact api from 1.6 to 2.0...

and maybe give a short snippet of how you insert the contacts to the
database.
maybe you do some (wrong) very time-consuming database-queries or you
just missed something, because i have seen my code using the contact db
implementation run way faster.. even with vcard-parsing  full blown
contacts...on the htc magic

cheers

Hi!
I have some questions concerning importing contacts to the device,
which is extremely slow.
First of all, if you delete all your contacts, google sync will
restore it very quickly. However, when my app is adding contacts to
the device, it's very slow (a few contacts per second). Even if I add
almost empty contacts (with name only), it is a time-consuming
process.
If I turn google sync off, importing 5000 contacts can take 1-2 hours
(on HTC Magic). When google sync is on it can take up to 24hours. And
this happens despite the fact, that application for the whole time is
in the foreground, device is connected to charger and screen is on. I
checked the logcat to make sure my app is adding the contacts the
whole time, and it is.
I tried different methods and different devices. The results differ of
course, yet manually adding contacts is always significantly slower
that google sync. Is there any way that I can speed up the process? So
that importing 5000 contacts will take less than an hour.

[android-developers] Proper way of importing contacts to the device/contacts operations are very slow

[android-developers] Re: Proper way of importing contacts to the device/contacts operations are very slow

2010-03-23 Thread cpphool

Hi!

Currently, I'm using HTC Magic (1.5) and Acer Liquid (1.6) to test the
app.

my sample code snippet for API  2.0:

for (int i = 0; i  100; i++) {
Log.d(TAG,iteracja  + i);
ContentValues personValues = new ContentValues();
personValues.put(Contacts.People.NAME, Test + i);
personValues.put(Contacts.People.STARRED, 0);
Uri newPersonUri =
Contacts.People.createPersonInMyContactsGroup(getContentResolver(),
personValues);
}


I did a few tests. Each time I changed NAME String in order to avoid
duplicates.

Results:
1) Acer Liquid (sync off) - 12 sec
2) Acer Liquid (sync on) - 30 sec
3) Acer Liquid (sync on) - 55 sec
4) Acer Liquid (sync on) - 35 sec
5) Acer Liquid (sync off) - 13 sec

1) HTC Magic (sync off) - 27 sec
2) HTC Magic (sync off) - stuck. log from logcat:

ERROR/CursorWindow(13459): need to grow: mSize = 1048576, size = 279,
freeSpace() = 162, numRows = 2789
ERROR/CursorWindow(13459): not growing since there are already 2789
row(s), max size 1048576
ERROR/CursorWindow(13459): The row failed, so back out the new row
accounting from allocRowSlot 2788
ERROR/Cursor(13459): Failed allocating fieldDir at startPos 0 row 2788
DEBUG/Cursor(13459): finish_program_and_get_row_count row 2213

then I turned the sync off and my application started running again
(without restarting the app)!  took 30 sec to complete.

Even if we turn off sync on HTC Magic it takes a long time to simply
add empty contacts. Adding 5000 empty contacts (without any other
operations) would take 1500sec = 25min.
