 Hi

 I'm doing enhancement to Android recovery feature for Freescale's i.MX
 platform.
 Main target is to add EXT3 partition support based on the original MTD
 partition, and let android rootfs running on movi-nand or SD card can
 do recovery.

 As the normal recovery procedure, recovery service unpacks the
 update.zip after reading update command. It reads the public key in /
 res/keys from rootfs into a structure before apply the update-script:
 typedef struct RSAPublicKey {
int len;  /* Length of n[] in number of uint32_t
 */
uint32_t n0inv;   /* -1 / n[0] mod 2^32 */
uint32_t n[RSANUMWORDS];  /* modulus as little endian array */
uint32_t rr[RSANUMWORDS]; /* R^2 as little endian array */
 } RSAPublicKey;
 This public key is used to decrypt the .SF file's signature stored
 in .RSA file, and compare to the .SF file's SHA-1 digest. This makes
 sure .SF file is correct.
 So in our recovery implement, we will have own keystore, and create
 own /res/keys.
 But I can not find the res/keys file in the android source or, in the
 recovery image which used to hack G1 to get root permission.

 My question is:
 1. Does the hacked recovery rootfs image remove this verification
 codes? (As I dump the recovery binary, seems no res/keys symbol)
 2. What's key file's format, and how to generate it from a
 certification file?


 Thanks.

[android-developers] Re: Bug in activity stack if launching from Home icon?

This is just an issue with how ADT launches the application, effectively
under a different identity so resulting in two instances running if you also
try to launch it from home.

 I've noticed some strange behaviour with resuming a task from a Home
 icon.

 Very easy to replicate, just create a new bare bones android project
 using eclipse, don't need to add anything. Then follow these steps:

 1. In eclipse, Run the project on a emulator or device.
 2. Once the app installs and launches the first activity, press Home
 key.
 3. Launch the app again by pressing its icon.
 4. Press Back key.

 Now this part seems wrong, you'll go back to the original activity in
 the stack, instead of the Home screen, even though its been previously
 launched and what you expect is it to bring back the stack as it was
 left, with one activity. If you repeat steps 2-3, it will just keep
 adding the same activity to the stack. That is until you press Back
 all the way through the stack to the Home screen.

 Now this behaviour will never again replicate. It will be the correct
 (?) behaviour of bringing back the stack history at the state it was
 when Home was pressed. Note there are no behavioural modifications,
 this is just a default application. However, I tried many combinations
 of launchModes and stack clearing, they had no effect on the first
 run.

 Unless I'm interpreting the documentation wrong, when the user presses
 the Home key, the task is moved in to the background and simply
 brought back the next time they press the app icon? Why is the app
 icon altering the task it creates, if it already exists (with no flag
 modifications)?

[android-developers] Re: Protocol Buffers (protobuf)

I don't know anything about protobufs, just that these are the classes the
developers use.

 Further investigation into com.google.common.io.protocol makes me
 believe that a custom Protocol Buffers compiler would be needed to

 a compiler exist?  Is it publicly available? Does it let me use a
 custom package name?

 I took a look at com.android.internal.location.protocol files and they
 look too uniform to be written by hand, though perhaps Google is just
 really hard on it's employees when it comes to standardizing coding
 style. ;)  If there isn't a compiler then there is little reason left
 for me to use Protocol Buffers over some of the alternatives since
 half the point was that I could write one .proto file and compile it
 for multiple platforms.

I also had trouble getting the GLUtils.texImage2D function to work on

recommend using the glTexImage2D function directly. You can look at my
Gears4Android demo (http://www.jeffboody.net/gears4android.php) for an

[android-developers] Re: ALL DEVELOPERS PIRATED APPLICATION ALL OVER!

2009-07-24 Thread Kaj Bjurman


What didn't you understand in my last reply? It is trivial unless I
have misunderstood something.

I guess you got unit tests? Now take the code below. Replace the
download/decrypt code in your unit tests with something like what I
posted previously:

Properties license = new Properties();
license.put(p, TelephonyMgr.getLine1Number());
license.put(d, Settings.System.getString(getContentResolver(),
Settings.System.ANDROID_ID);
license.put(e, aDateInTheFuture);

Then run your unit tests again. Downloading won't fail since we have
_replaced_ the download code, and no decryption would fail, since we
aren't decrypting anything. We replaced that code as well. You don't
even need to find all license check snippets that the developer has
springled his code with, since they all will check against our valid
license that we created above.

I really can't believe that you don't see this. Please tell me in what
way it fails given my description above.



On 23 Juli, 23:07, Al Sutton a...@funkyandroid.com wrote:
 We're going to update the page, but we'd kind of assumed it was an
 obvious thing to check.

 As for your latest idea, the download code downloads an encrypted file
 so an error would be thrown during decryption which would show up
 problmes with a spoof server or modified download code.

 I think you get my point. You may think it's trivial to circumvent,
 but when you get down to it there are various things we've done to
 make it a lot trickier than an initial inspection would make you
 believe, which is why you've still not come up with a reproducable
 system for cracking it. Even if you did crack a version of an
 application, the steps you took wouldn't be easily reproduced for
 other applications and even other versions of the application if the
 developer moved the decryption/test code around.

  Shouldn't the code on the page say that in that case, and it's still

  and so on.

  I think you get the point. We have enabled all settings. Remember I'm
  not a hacker/cracker and I have already shown you that it's very easy
  to crack your system. You aren't protecting the code. Applications
  will still be pirated very easy, and it's even possible to write an
  application that does it automatically.
  Users of the applications will also be very frustrated if they for

   that property isn't present.

Sorry to say, but there's a huge flaw in your examples. The snippet
below is taken from your link:

X509EncodedKeySpec keySpec = new X509EncodedKeySpec
(ANDAPPSTORE_APP_KEY);
KeyFactory factory = KeyFactory.getInstance(RSA);
PublicKey key = factory.generatePublic(keySpec);
Cipher cipher = Cipher.getInstance(RSA/ECB/PKCS1Padding);
cipher.init(Cipher.DECRYPT_MODE, key);
byte[] original = cipher.doFinal(LICENSE);

Properties props = new Properties();
props.clear();

ByteArrayInputStream bis = new ByteArrayInputStream(original);
try {
  props.load(bis);

} finally {
  bis.close();
}

Very few classes are using using e.g X509EncodedKeySpec, so it's very
easy to find all classes that are using it, and it's thus very easy to
find that section of code. Now replace all operands in the class file
with no operation instead, except this part:

Properties props = new Properties();

I.e. we are creating an empty license.

Now read all your other code snippets with this in mind.

E.g.

4(c)(i). Testing the phone number

String licensePhoneNumber = license.getProperty(p);
if( licensePhoneNumber != null ) {   //Uh, uh. An empty license
returns null, we won't do any checks.

  TelephonyManager TelephonyMgr =
      (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);

  String devicePhoneNumber = TelephonyMgr.getLine1Number();

  if(licensePhoneNumber.equals(devicePhoneNumber) == false) {
    throw new RuntimeException(** Phone Number Check Failed **);
  }

}

Remember that license now is an empty instance

[android-developers] Re: Is there a way to auto-power on the phone?

2009-07-24 Thread Cédric Berger


Would be a good addition for future.
But note that compared to most other phones, power on from total
shutdown is quite long.

What would be good is an option to go to hibernate (not only sleep).
Even without programmed wake up, this would allow to shutdown your
phone and start it up again without :
1-waiting for whole boot process (if you need to make an emergency
call I imagine how frustrating this would be ! -Maybe an easy boot

[android-developers] Re: Android Toast Duration

2009-07-24 Thread Mohamed Amir


Thank you for all those who replied.

But Toast is the only UI component I could find that appears over the
incoming call dialog.  I need to show some information when an
incoming call arrives.  This is why I am using the Toast.




On Jul 24, 1:34 am, Dianne Hackborn hack...@android.com wrote:
 It sounds like you are abusing toasts.  How about just showing your own
 dialog that is set up to not get focus or be touchable?  You can use this
 background to make it look like a toast:

 And this animation style for the same fade effect:

                         t.setView(v);

  Is there some limit to the number of times that show() method can be

  Any ideas to increase that duration?

If you aren't programming with the SDK, you are in the wrong group -- you
probably want android-porting.

Also, as I said, this function isn't there for you to just call.  You
haven't said what you are trying to do, so there's not much I can do to
help, but you  probably want to look at PhoneWindowManager and
WindowManagerService for the code that manages the screen orientation.

[android-developers] Re: ALL DEVELOPERS PIRATED APPLICATION ALL OVER!


The confusion arose because your previous post said Replace the code
that downloads the certificate and encrypts it, in this post you're
talking about the download/decrypt code, the first is a combination
of client code (download) and server code (encryption), the latter is
client-only code.

Referring to the download/decrypt replacement, the problem here is the
amount of time it would take to find where the download/decrypt code
resides in a compiled app, replace it, and recompile it. If you had
the original source code then yes, you could do a drop in replacement,
but if you had the source code you could easily strip out any
protection mechanism.

Seriously, try it on a compiled application, you'll find it takes you
a lot longer than you think, and longer than many crackers would be
willing to spend on a low-cost app.

 I guess you got unit tests? Now take the code below. Replace the

 Properties license = new Properties();
 license.put(p, TelephonyMgr.getLine1Number());
 license.put(d, Settings.System.getString(getContentResolver(),
 Settings.System.ANDROID_ID);
 license.put(e, aDateInTheFuture);

 Then run your unit tests again. Downloading won't fail since we have
 _replaced_ the download code, and no decryption would fail, since we
 aren't decrypting anything. We replaced that code as well. You don't
 even need to find all license check snippets that the developer has
 springled his code with, since they all will check against our valid
 license that we created above.

 I really can't believe that you don't see this. Please tell me in what

  I think you get my point. You may think it's trivial to circumvent,
  but when you get down to it there are various things we've done to
  make it a lot trickier than an initial inspection would make you
  believe, which is why you've still not come up with a reproducable

[android-developers] Dealing with CPU-hogging processes

2009-07-24 Thread sasq


This is not strictly a developer question, but it's technical enough
that I don't know where else to ask it.

For a while now I have been running top on my HTC Magic whenever I
suspect it of using more CPU then normal, and often I see some process
constantly using CPU (From 10% to 80% in some cases). Sometimes its
system_server, sometimes it's com.android.browser or com.htc.album.

Is there any way to deal with this except restarting? Because a
program I write is not allowed to kill other applications I suspect?

Is there something that can be done by Android itself and if so will
this problem be fixed in later versions? Or is it only a matter of
application developers writing better code?

No, Not need to change the movie file. You have to modify your

Hello fellows,
I’ve already tried to find the solution in other POSTS but none of
the solutions worked.
The problem that I have is that the loaded texture not displayed in
the real device (G1, firmware 1.5). If I turn of the texture and put a
color in the geometry, it works fine.
Details: the file that I’m loading has width and height power of 2.
And I tried with .bmp and .png files, for both I had the same
problem.
Let me know if you know what is going wrong and what I should do.
My code works fine in the emulator but not in the real device.
(This

Thanks a lot for your attention.

[android-developers] Re: Soft references freed too early

2009-07-24 Thread brian.schimmel


Hi fadden,

thanks for your answer and for looking things up in the dalvik source.
Sounds very much like you are right.

I didn't know of dalvik.system.VMRuntime.setMinimumHeapSize() but now
tried it. Invoking that with 4 MB or 5MB has no visible effect. But
invoking it with 8MB solves my problem.

So while my needs are fullfilled now, at least until Android 1.6 or
2.0 comes out and dropps support for setMinimumHeapSize, I had some
insights I want to share:

Interestingly, while doing some benchmarking it turned out that the
real heap size and heap usage is not increased by this. I called
setMinimumHeapSize jsut before the caching/prebuffering starts. I've
compiled my app with different values and used the eclipse DDMS view
to query the heap usage at three important times in my application
life cycle:

Step 1: Start the application and wait for the caching to be done,
then GC
Step 2: Open up another activity that displays a visual list, showing
the first 9 objects, then GC
Step 3: Scroll several times up and down through the list, until
scrolling is smooth, then GC

Without using setMinimumHeapSize:
Step 1: 3,258 used: 2,473
Step 2: 3,445 used: 2,571
Step 3: 3,508 used: 2,639

runtime.setMinimumHeapSize(400);
runtime.setTargetHeapUtilization(0.9f);
Step 1: 3,195 used: 2,485
Step 2: 3,508 used: 2,580
Step 3: 3,508 used: 2,583

runtime.setMinimumHeapSize(500);
Step 1: 3,250 used: 2,386
Step 2: 3,258 used: 2,517
Step 3: 3,383 used: 2,595

runtime.setMinimumHeapSize(800);
Step 1: 3,320 used: 2,480
Step 2: 3,320 used: 2,519
Step 3: 3,320 used: 2,531

As you can see, there is now big difference in those values. Anyway,
only when setting the heap to 8MB, none of my weakly referenced
objects where thrown away, and in Step 3 I instantly get a smooth
scrolling list.

The usage is always around 76%. I noticed there is a method
setTargetHeapUtilization and tried it once, supplying 0.9f as
parameter. As you can see in the above numbers, doing it results in
the same actual usage around 76%.

with best regards,
Brian schimmel

  Object 6 is cached

  and so on.

 I don't believe this is the desired behavior.  Looking at tryMalloc()
 in dalvik/vm/alloc/Heap.c, it initially calls gcForMalloc(false),
 which should not be attempting to collect soft references.  Only
 later, when confronted with the possibility of throwing OOM, does it
 call gcForMalloc(true).

 Hmm.  In dvmHeapSizeChanged() there's a SOFT_REFERENCE_GROWTH_SLACK
 value that appears to be trying to strike a balance between expanding
 without limit and collecting objects.  If there's no cap we might fill
 16MB with softly-reachable objects before we discard any of them,
 which isn't desirable on a device that has multiple applications
 resident in memory.  It appears the function wants the GC to collect
 some of the soft references, which sounds good, but it looks like
 SR_COLLECT_SOME doesn't receive special treatment during the mark 
 sweep.  In the current implementation, it's all or nothing.

 So my guess is you've got more than 128KB of softly-reachable objects
 (i.e. the things that are softly referenced, and the things that are
 only reachable through them).  When the GC has to choose between
 expanding the current heap size and chucking the soft references, it's
 choosing to discard some, which in the current implementation means
 all.

 The observed behavior changes after you have a bunch of other stuff
 allocated, because the soft limit is higher, and the GC doesn't have
 to choose between expanding the heap and collecting the soft
 references.

 You might be able to work around this behavior by calling
 dalvik.system.VMRuntime.setMinimumHeapSize() (which really shouldn't
 be exposed in the API, but there it is).  If you start it out at 4MB
 that might prevent you from thrashing like this right after the app
 starts up.  I think the issue will come back if you manage to get
 close to the soft limit again, but I don't think that's avoidable
 without a change to the GC behavior.  (There are some kluges you could
 employ to suppress the behavior, like periodically grabbing hard
 references to all cached items, allocating something large, discarding
 it, and un-refing the cache entries, but that's ugly and might not
 work anyway.)

 I'll file a bug against the GC.

When are you calling getCurrentPosition()?

I am using getCurrentPosition() to update an elapsed-time counter in a
video player, and it definitely works. I use MediaPlayer rather than
VideoView, so it could be that this explains the difference in behavior.
 However, if you are calling getCurrentPosition() too late, it may be
the video has stopped and, therefore, is actually at position 0.

As I said previously. I have tried to protected java applications, and
I have done what I described with pure java applications, without
having the source code (I have even done it in assembler/machine code
on non java applications). I don't know much about the dex format and
what tools that are available to modify compiled classes, but it's
only a matter of time before they are here, if they don't exist right
now.

Crackers don't think about if a program is expensive or not. They only
want to get known for their talents, and they crack all popular
applications, even if they are almost for free. So all popular
applications get cracked, regardless of price, and time isn't an issue
for the cracker. He doesn't think in economical terms.

 Referring to the download/decrypt replacement, the problem here is the
 amount of time it would take to find where the download/decrypt code
 resides in a compiled app, replace it, and recompile it. If you had
 the original source code then yes, you could do a drop in replacement,
 but if you had the source code you could easily strip out any
 protection mechanism.

 Seriously, try it on a compiled application, you'll find it takes you
 a lot longer than you think, and longer than many crackers would be
 willing to spend on a low-cost app.

Ah, I've now run into this issue also, it seems. Strangely, it works

 I tried it twice and ended up in the exact same place both times.
 With the bug fix in place it started up every time.
 
 This problem will go away in a future release, but for now you can
 work around it by forcing initialization to happen earlier.  The
 easiest way to do this is to call Class.forName(String className)

 $LoadedAnnouncement and see if that cures it.

[android-developers] App opens previous activity - but only intermittently

2009-07-24 Thread Anna PS


Hi all,

This is an intermittent bug in one of my apps. I don't expect anyone
to solve it immediately, but I'd appreciate any thoughts on how to
start debugging!

So, my app lets users edit an item (in the EditPage activity). When
they press the Back key, the desired behaviour is that it saves their
edits and returns them to the home page (the HomeList activity). The
code for this is below. It works fine. Except...

The bug is this. Some users report that sometimes when they reopen the
application after a pause, they are seeing *not* the home page, where
they left the application - but the previous edit activity. Crucially,
they are also seeing the edit activity without their saved edits -
effectively losing their most recent edits :(

I've been able to reproduce this myself. It only happens after the
application hasn't been opened for a while. If I save something,
minimize the application and reopen it straight away, it shows the
HomeList activity just fine, and the edits have all been saved. But if
I save something, leave it for a couple of hours and then reopen it,
it shows the previous EditPage activity, without the saved edits (i.e.
in the state that the EditPage activity was previously launched).

Any ideas, anyone? I had wondered whether it was due to the Back
button being used to return the user to the HomeList activity - maybe
Android thinks that the Back button means that the HomeList is not the
most recent activity, instead the EditPage is. I'd like to carry on
using the Back button if possible, though. And in particular, I'm
puzzled why it only happens after the app has been idle for an hour or
so, and not immediately? Is it something to do with Android's memory
management?

As I say, would appreciate any tips on how to debug - quite baffled at
the moment!

Thanks very much,

Anna

--

Code used in the EditPage activity to save edits when the Back key
gets pressed. Works fine, apart from bug described above.

// Save everything when the Back key gets pressed
public boolean onKeyDown(int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_BACK) {
if (saveEdits()) {
Context context = getApplicationContext();
CharSequence text = ' + title + ' has been 
saved;
int duration = Toast.LENGTH_SHORT;
Toast toast = Toast.makeText(context, text, 
duration);
toast.show();
Intent i = new Intent(EditPage.this, 
HomeList.class);
startActivity(i);
} else {
// failed to save!
showDialog(SAVE_WARNING);
}
}
return false;
}

[android-developers] Re: How to open or register a new file extension in Android?

2009-07-24 Thread alex


I see. Something as simple as
intent-filter
action android:name=android.intent.action.VIEW /
category android:name=android.intent.category.DEFAULT /
category android:name=android.intent.category.BROWSABLE /
data android:scheme=file /
data android:mimeType=*/* /
data android:pathPattern=.*epub /
/intent-filter
would catch all file downloads from browser. I'll dig more into this.
The only thing I can suggest so far is:
1) have a wildcard intent filter to catch all files
2) check the file extension in onCreate(), onNewIntent(). if matches,
handle it, pass the received intent with startNextMatchingActivity()
otherwise.
This is ugly but at least will work.

   I have problem with adding a new file type to android(the file  type

   I know that I need to write a special intent-filter for that,but I
   don't know how,because this format hasn't any special,registered  MIME
   type.
   I tried to write in AndroidManifest.xml to open a file test.comap:
                      intent-filter
                                   action
   android:value=android.intent.action.VIEW /

   android:host=* android:path=sdcard/test.comap /
                       /intent-filter
   But this doesn't work.
   How to do it right?

[android-developers] Re: Pausing VideoView when launching a new intent...

2009-07-24 Thread junker37


I call getCurrentPosition on the onPause method of my activity.  So,
what you're saying is maybe before onPause is called, the video has
been stopped already?  That makes sense.  I'll look at th activity
lifecycle again and see if there is another method I should use to
pause the video.

 When are you calling getCurrentPosition()?

 I am using getCurrentPosition() to update an elapsed-time counter in a
 video player, and it definitely works. I use MediaPlayer rather than
 VideoView, so it could be that this explains the difference in behavior.
  However, if you are calling getCurrentPosition() too late, it may be
 the video has stopped and, therefore, is actually at position 0.

2009-07-24 Thread junker37


I took a look at the activity lfiecycle again and it seems onPause
would be the only place I could get the current position before the
activity is paused.

The video has definitely not finished playing before onPause has been
called.  Is it possible that videoView.getCurrentPosition has not been
implemented yet?

 implemented yet?

No, it is implemented. Search Google Code Search for:

package:android videoview

and you will see the implementation. Most likely, by the time onPause()
is called, the underlying MediaPlayer instance is stopped.

The two differences in my case:

1. I'm using MediaPlayer directly, rather than VideoView, so I get
finer-grained control over matters. You can see a sample video player
using MediaPlayer over here:

https://github.com/commonsguy/vidtry/tree

2. I am simply using postDelayed() to get control once a second and am
updating a visual elapsed-time counter at that point based on
getCurrentPosition() (note: this is in a separate project than the
vidtry app I link to above). You could do the same thing, caching the
last-known position for use when onPause() is called. You might be a
second off, but I would hope that users would be amenable to that.

[android-developers] Re: ALL DEVELOPERS PIRATED APPLICATION ALL OVER!


And as I've said before they would need to do a crack per app and
potentially per version of the app if the developer so desired.  Its'
a technique I've used for several years on various applications and
I've always offered up the source code so people see for themselves
it's not a trivial thing to crack.

Anyway, we're getting way off topic, so unless you're actually going
to try and do what you think is possible I can't see any benefit in
continuing this discussion, because from what you're saying you're
putting across an opinion that a task is relatively trivial without
any knowlege of the tools needed to do the job or having ever tried to
do it.

[android-developers] Save onDraw canvas

2009-07-24 Thread doubleslash


I want to to animation as follows. The first call of onDraw, I will
draw the scene. Subsequent times, I want to translate the scene, by
doing canvas.translate(dx, dy), but the canvas returned by onDraw is
always blank. Thus, I have to redraw the whole scene again.

public void onDraw(Canvas canvas){
canvas.translate(dx, dy);
drawScene(canvas);
}
 Is there anyway I can save the scene drawn on to canvas from the
first time so that subsequent times, I just need to translate? This
will improve performance significantly.

method of MapView class it's giving Null Pointer Exception .  I even
tried other constructor of MapView class like

MapView( this, 02OwWVKUsUMSUwUZPEOHkWSQge2bW6FOISMYvDw) ;

I even checked whether mapv contains null or not [ using mapv.equals
(null)] . But it's not null either.

But problem remains the same .  Please help .

  I've noticed some strange behaviour with resuming a task from a Home

  Very easy to replicate, just create a new bare bones android project
  using eclipse, don't need to add anything. Then follow these steps:

  1. In eclipse, Run the project on a emulator or device.
  2. Once the app installs and launches the first activity, press Home
  key.
  3. Launch the app again by pressing its icon.
  4. Press Back key.

  Now this part seems wrong, you'll go back to the original activity in
  the stack, instead of the Home screen, even though its been previously
  launched and what you expect is it to bring back the stack as it was
  left, with one activity. If you repeat steps 2-3, it will just keep
  adding the same activity to the stack. That is until you press Back
  all the way through the stack to the Home screen.

  Now this behaviour will never again replicate. It will be the correct
  (?) behaviour of bringing back the stack history at the state it was
  when Home was pressed. Note there are no behavioural modifications,
  this is just a default application. However, I tried many combinations
  of launchModes and stack clearing, they had no effect on the first
  run.

  Unless I'm interpreting the documentation wrong, when the user presses
  the Home key, the task is moved in to the background and simply
  brought back the next time they press the app icon? Why is the app
  icon altering the task it creates, if it already exists (with no flag
  modifications)?

[android-developers] Re: Android BUG....

2009-07-24 Thread dotclick


As a IT Architect working for several fortune companies, I can very
well appreciate the prioritization process that is required to manage
defects.

My concerns here is that this was low-hanging fruit and should have
only take one (1) developer about an hour or so to resolve.

My clients concerns regarding this it affect their ability to manage
customers with the same phone numbers.  All they really wanted was an
ETA on the resolution.  They might have been fine if it was another
6-9 months, however, what was not acceptable to them was the Google's
inability to provide basic communication on a defect that affected
them.

Again, don't get me wrong... I want Android to succeed.  I think its
got great potential, but someone has to pay attention to functional
and usability aspects so something this dumb doesn't doesn't end up in
release software again.

  It seems curious that you seem to have made the same error that you are

  Of course, it is also curious that you appear to think this is an
  end-user tech support forum (which it is not) and that it is Google's
  primary responsibility to respond to you here (which it is not).

  But I digress.

   No status updates or responses on the bug report from 7+ months ago.

  Please point out the official public bug trackers for Windows Mobile,
  Blackberry, iPhone, and Palm WebOS. I'm not even sure there's one up for
  Symbian, and they're at least on the road to open source.

  Please point out where you get detailed, bug-level information months in

  Please point out how you -- whether via your own engineering efforts, or
  by hiring somebody, or by collecting interested people to raise money to
  hire somebody -- have a chance to fix bugs in Windows Mobile,
  Blackberry, iPhone, or Palm WebOS, as you can with Android. I'll give
  Symbian a mulligan here, since they're in progress on this issue.

  Had this same bug, or an equivalent one, affected you on one of these
  other platforms, the best-case scenario is that, after sitting in
  indefinite tech support queues, you would be told it is a bug and it may
  get fixed someday. Here, not only were you able to file the bug report
  without much effort (albeit with no better of a response), but you have
  options for spearheading a fix, which you lack with any other
  commercial-grade smartphone platform.

  Now, you may not elect to use any of those options to accelerate a fix,
  but that's your decision, not Google's. Regardless, you are no worse off
  than you would have been with any other platform with the same sort of bug.

  If you want to whine about how Android has bugs, be my guest, just don't
  whine about the lack of response, since that's all you'll get from anyone.

  Note: once Symbian gets a-rollin' in earnest on the open source front,
  the bar for Google and Android may get raised a fair bit, but we're not
  there yet.

[android-developers] Re: finish() won't close activity

2009-07-24 Thread Lewis Z.


After more debugging, it seems to me that some MotionEvent events
don't like no handling and are acting up.


On Jul 23, 6:26 pm, Lewis Z. lzh...@gmail.com wrote:
 I have an EditText field and I want to pop up a new window/activity
 whenever a user touches/clicks the field. The new window has some

 Everythings work fine until I click the Apply and Cancel buttons. The

 one more time. Calling popMaskEditor() from a button's OnClick event
 handler doesn't have this problem.

 Can someone please tell me why? How to fix this problem? Thanks a lot.

[android-developers] Re: Launching a Service at the startup

2009-07-24 Thread Nmix


First, I have no desire to be evil. Yet I have an app that must listen
for events, and it seems that the only way to hear those events is
with a listener in a persistent service that starts up on device boot.
The reason is that not all those events have a corresponding
broadcast. There are also efficiency and UI issues in that data
structures need to be rebuilt every time the service must start to
deal with events. A particular example of interest to me is
PhoneStateListener, and in particular incoming phone calls. I see no
way around having a persistent service at this time, and in fact I
need to take some special action to fairly quickly get the service
going again should the system kill it. After all, the user downloaded
the app and expects it to do what we say it does.

Is there a better approach that meets the requirement yet also plays
well with resource contention? Will there at least be more broadcasts
in future that will complement additional listener events? I know this
is asking for a lot, so perhaps being evil for now is in fact the
lesser evil. I really do want the app to cooperate with the Android
environment.

 Mark answered how to do this, but please: think again about whether you

 On current Android devices, we can keep only a small handful of applications
 running at the same time.  Having your application do this is going to going
 to take resources from other things that at any particular point in time
 would be better used elsewhere.  And in fact, you can be guaranteed that
 your service will -not- stay running all of the time, because there is so
 much other stuff that wants to run (other background services that are only
 running when needed will be prioritized over yours), or needs more memory
 for what the user is actually doing (running the web browser on complicated
 web pages is a great way to kick background stuff out of memory).

 We have lots of facilities for implementing applications so they don't need
 to do this, such as alarms, and various broadcasts from events going on in
 the system.  Please please please use them if at all possible.  Having a
 service run forever is pretty close to the side of evil.

I run into this on occasion as well with Ubuntu, where the emulator
launch seems to stall on the Android-with-animated-gleam screen. I've
just been assuming there's some race condition bug in the emulator/qemu
interaction. As you indicate, closing the emulator and trying again
seems to work for me.

[android-developers] expected apps for...

2009-07-24 Thread LT


video playback
music playback
file compression/decompression
internet browsing

in these categories, are there standard applications that will be part
of the OS?  if so, what are they and what are the capabilities?

i am assuming Chrome will be the browser for internet browsing.  but
what about file compression/decompression?

and of course video and music playback?

will Picasa be available for Android?

[android-developers] Re: Show notification dialog during incoming call.

2009-07-24 Thread Arno Becker


Hi Ronald,

try to use a builder for the dialog in the onCallStateChanged-method
of your PhoneStateListener.It has to know the Context of your Activity
the PhoneStateListener runs in.

AlertDialog.Builder builder = new AlertDialog.Builder(context);
builder.setMessage(Are you sure you want to exit?)
  .setCancelable(false)
  .setPositiveButton(Yes, new DialogInterface.OnClickListener
() {
   public void onClick(DialogInterface dialog, int
id) {
   Log.d(TAG, onClick(): entered...);
   }
   })
   .setNegativeButton(No, new DialogInterface.OnClickListener
() {
   public void onClick(DialogInterface dialog, int
id) {
dialog.cancel();
   }
   });

AlertDialog alert = builder.create();
alert.show();

[android-developers] Floating button ... ?

2009-07-24 Thread Emre A. Yavuz



Hi,

 

I was wondering whether anyone has written any code to implement a customized 
button that can be placed anywhere on the device screen (probably based on 
coordinates etc.) which will sit on top of a layout.

 

Say, you have a LinearLayout with a couple of vertical sublayouts drawn on a 
background and you want to add a button somewhere on the display.

 

Cheers,

 

Emre

[android-developers] Have ListView and other widgets scroll as a whole

2009-07-24 Thread MarcoAndroid

Hello all,

I'm trying to achieve the following with my Android search app:

- 2 input boxes where the user can enter criteria to search for
- 1 search button
- when the search button is clicked, a search is performed and on the
same page the matches are shown *below* the 2 input boxes and search
button.
- the results can be quite a few (say up to 50), which won't fit all
on the viewable part of the screen, so the user has to be able to
scroll down in the results.
- when the user scrolls down over the results, the 2 input boxes +
search button should of course also scroll up out of sight.

Basically the behaviour you get when you for example do a google
search on google.com. But, for clarity: I don't want to use the
WebView.

Note that there should be no scrollbar for the results only (that can
be done easily with a standard ListView), the all needs to scroll as a
whole.

The reason I want this behavior is that I don't want to direct the
user to a next screen with the search results; that would be so
annoying having to go back to the search screen all the time if you
want to enter another search criteria, like if you figured out you
made a typo.

Now I've read most posts about possible solutions, quite a few people
asked for this before, like:

http://groups.google.com/group/android-developers/browse_thread/thread/b7d2b7c275ac730f/803f40201920c6d9?lnk=gstq=scrollview+listviewpli=1
http://groups.google.com/group/android-developers/browse_thread/thread/3bfb013704d886fb/a556ab75f22c8dd1?lnk=gstq=scrollview+listview
http://groups.google.com/group/android-developers/browse_thread/thread/af85d0ccddfd10d7/b4d705341719382c?lnk=gstq=scrollview+listview
http://groups.google.com/group/android-developers/browse_thread/thread/77acd4e54120b777/00fe963ec94d78ad?lnk=gstq=scrollview+listview
http://groups.google.com/group/android-developers/browse_thread/thread/a05227c317c8ad8d/86e6f054fba30828?lnk=gstq=scrollview+listview
http://groups.google.com/group/android-developers/browse_thread/thread/fd0da00fe94ffed8/1d3bd9b81dd7d3e3?lnk=gstq=scrollview+listview

But I haven't been able to find the real solution for my requirements.
I've also not seen any apps yet that do implement anything like this,
though I haven't seen all apps.

This what I already tried on the emulator:

a) ListView inside a Scrollview. Thus:

Scrollview
EditText
EditText
Button
ListView
/ScrollView

The app looks like I want it; I calculate the total height of the
ListView items and set the ListView's height to that. This way there's
no scrollbar on the ListView itself, only the Scrollview's scrollbar
shows. And I can scroll down in the ListView entries using the down
key.
Problems: multiple posts mention to NOT do this, scrolling gets
confused. And indeed, although the result is exactly how I want it to
look, scrolling acts up: stepping through the entries in the list
below what's visible, scrolling of the whole (performed by the
ScrollView) stops until the last entry is reached!
So unless I maybe make my own custom ListView that doesn't perform any
scrolling (or whatever fixes this behaviour), this solution is a dead
end. Any tips would be most welcome.

b) Fixed listviewheader in a ListView (no ScrollView) containing the 2
boxes and searchbutton, more or less like
http://jsharkey.org/blog/2008/08/18/separating-lists-with-headers-in-android-09/
and in the API demo Views/Lists/8. photos. Thus:

LinearLayout
ListView
/LinearLayout

In the code I then set the header of the list to this separate view:
LinearLayout
EditText
EditText
Button
/LinearLayout

Problems: Firstly: the user has to scroll a lot more to see all
results because the header keeps occupying the top of the screen.
Secondly, with the emulator up-key I can't step (focus) onto the
Search button or input boxes anymore! If I turn on focusability for
the header, I can only step up onto the whole header, not the
separate fields. If I turn it off, nothing happens, I can only scroll
up to the top entry in the resultlist.
Thus this might work (though not completely matching my requirements),
but only if is it possible to make the inputboxes + searchbutton part
of the scrolling up focus sequence. Is this possible?

c) Inputboxes + search button separate from the ListView, having the
inputboxes + search button fixed on top, ListView below them,
scrollable (e.g. in a FrameLayout). Got this to work, but I don't want
the inputfields to be fixed, so just like b) dismissed.

- Other solutions mentioned in posts but not tried yet:
1) use a LinearLayout per entry and attach an adapter to it, having
listeners on the adapter to reload the layout. Could this give me the
behaviour I want?
2) use tabs. Nope that's a completely different look and feel than
what I'm trying to achieve.
3) use ViewFlipper or one of its kin and create your own setup for
flipping between the list and the rest of the contents of the
ScrollView. Sounds interesting, but are there any examples of this or

[android-developers] Security application needs developer.

2009-07-24 Thread Eric Lee Elliott


This application is yours for taking.

Phone camera would detect intruder movement, photograph intruder, send 
photograph to remote storage, send text messages asking help, send 
current phone GPS position  resume camera motion detection after 30 
more seconds.  Phone would not indicate security app is operative or 
available.  If thief steals phone, owner would continue to get pictures 
 location of thief.  Application would include all Find My Iphone 
functions except needing subscription to external service.

Comparable service at fixed location would cost me $1200 plus $45 per 
month.  For $10 per month, I could add a phone to my account  use it 
for 24 hour security anywhere is cellular service.  Also could use 
existing phone while I sleep.

Please develop this application so I can use it.

I have seen for example the Payforit solution in UK, but it is not

[android-developers] Re: run app after installation using PACKAGE_ADDED or other mechanism?

I don't understand what you mean about persistent alarms -- alarms are
persistent, until a reboot, at which point yes if you want to have alarms
scheduled you need to handle BOOT_COMPLETED.

Also the next version of the platform should allow an app to be told when it
is updated, though you still will deliberately not be launched when first
installed.

On Tue, Apr 14, 2009 at 5:39 AM, M. Dodd intern...@gmail.com wrote:


 All nice and well - if the API for AlarmManager supported persistent
 alarms.

 Currently, if you update an application your alarms will go bye bye
 until the phone reboots - no?

 Requiring a reboot just to reset a few silly alarms seems quite
 excessive to me - and definitely prevents us from taking full
 advantage of the platform.

 So my question: has anybody implemented this in some way?

Yes.

You should be able to use my recently-released MergeAdapter:

https://github.com/commonsguy/cwac-merge/tree

You would hand the MergeAdapter your initial set of ordinary views, plus
an empty Adapter of some form for your search results. When your search
is complete, populate your formerly-empty adapter with the results, and
they should show up.

If that doesn't work, it's a scenario I need to support myself within
the next couple of weeks, so we should be able to get it going for you
one way or another.

I'll be adding more documentation about it in the coming weeks, both in

[android-developers] Re: App opens previous activity - but only intermittently

2009-07-24 Thread nEx.Software


Well, I'd say if you are done with the EditPage activity, then you'd
want to call finish() on it. I assume that the way this this works is:
User is on HomeList, hits some button (or other trigger) to open
EditPage, makes edits on EditPage, hits Back to go back to HomeList?
If that is the workflow, I'd say you would want not to use
startActivity(i) to go back to HomeList, but rather simply finish()
EditPage.

 Hi all,

 This is an intermittent bug in one of my apps. I don't expect anyone

 So, my app lets users edit an item (in the EditPage activity). When
 they press the Back key, the desired behaviour is that it saves their
 edits and returns them to the home page (the HomeList activity). The
 code for this is below. It works fine. Except...

 The bug is this. Some users report that sometimes when they reopen the
 application after a pause, they are seeing *not* the home page, where
 they left the application - but the previous edit activity. Crucially,
 they are also seeing the edit activity without their saved edits -
 effectively losing their most recent edits :(

 I've been able to reproduce this myself. It only happens after the
 application hasn't been opened for a while. If I save something,
 minimize the application and reopen it straight away, it shows the
 HomeList activity just fine, and the edits have all been saved. But if
 I save something, leave it for a couple of hours and then reopen it,
 it shows the previous EditPage activity, without the saved edits (i.e.
 in the state that the EditPage activity was previously launched).

 Any ideas, anyone? I had wondered whether it was due to the Back
 button being used to return the user to the HomeList activity - maybe
 Android thinks that the Back button means that the HomeList is not the
 most recent activity, instead the EditPage is. I'd like to carry on
 using the Back button if possible, though. And in particular, I'm
 puzzled why it only happens after the app has been idle for an hour or
 so, and not immediately? Is it something to do with Android's memory
 management?

 As I say, would appreciate any tips on how to debug - quite baffled at
 the moment!

 Thanks very much,

[android-developers] Re: How can i show email notification?

2009-07-24 Thread Yusuf T. Mobile


The Android SDK has a feature for notification:
http://developer.android.com/reference/android/app/Notification.html

That would not only make your job easier, but would make the
notification consistent with the standard Android UI.

[android-developers] Re: App opens previous activity - but only intermittently

2009-07-24 Thread Yusuf T. Mobile


That's a creative way to work with Android lifecycle management. In
fact you don't need to tell Android to go to the Home page when the
user presses the back button. If you did nothing special when the user
pressed the back button, Android would call onPause() and go to the
previous Activity.

Activities are like a stack. So when you call startActivity(), you are
telling Android put this activity on top of mine. Instead, just wait
for Android to tell your Edit activity that it's about to go away
(from the back button which pops one activity off the stack, or the
home button which pops them all, or other causes), and save your data
in onPause(). You can then reload it in onResume() when Android tells
your activity to start back up. Incidentally, Android also calls
onResume() the very first time your activity is launched.

In case you've not seen the activity lifecycle description, here it
is: http://developer.android.com/guide/topics/fundamentals.html#actlife
