Re: [android-developers] Re: My Newbie problem with compiling the HelloAndroid App

[Mukesh Srivastav]

Dude,

Very simple problem u have it. Please look at my below statment that would
help in resolving.

1. open the Activity ( I mean Java source code)

2. in your Java File, you might added the following import statment

import android.R;

3. Remove that import statment and add your package statment, see below

  import.helloworld.R --->  Example, you add your packagename.

[android-developers] Re: How to READ a MODE_WORLD_READABLE file from ANOTHER application

[Saied]

Now I learn that the .txt asset files get compressed, and openAssetFd
fails on compressed files!

Wow.

is there a workaround for this?

I just changed the extension to .jpg and it worked, but that's UGLY.

Any thoughts?

Thanks.

If you store it as a raw resource instead of an asset, it won't get
compressed. I *think* there is a sample on how to this from a CP
in the SDK sample code, but not 100% sure.

Re: [android-developers] Re: Not able to get full App logs

[Mukesh Srivastav]

1. Close the emulator.

2. Got to ADB, Delete the existing emulator

3.Create a New Emulator.

4.Restart the Eclipse... (Please try this step first, if  you still not
able to see the logs, then do the above four steps).

[android-developers] Reg: Crash in the native while allocating memory

[Aluvala Suman]

Hi All,

I am facing a crash issue while trying to allocate a dynamic memory of size
1150 bytes in the android native.
Its crashing in-consistently at malloc() function in the android native and
some times at free().

The native code which I am using is fully developed and tested (using
purify) as well.
I am trying to port that code (in c) to Android.

I have already posted this in stackoverflow (Link for stackoverflow
post).
But I didn't got any answer from any one.
Do I need to set any flags specially for andorid-ndk?

I am using r7 NDK.
Android 2.3.3 API Level 10 Emulator.

Please help me in resolving the same.

Thanks & Regards,
SSuman185

[android-developers] Re: User cannot install an update

[mot12]

There may be a permission problem so the userID given to the app does
not match the userID of the app data directory. If your user has root,
tell him/her to delete the directory /data/data/com.yournamespace...
Then reinstall the app.

Unfortuantely, only root can do this. Uninstalling the app should
delete the app directory but doesn't sometimes if there's a permission
problem.

It turns out that raw resources are also compressed, and therefore

Is there a sure way to prevent this?

Well, you are opening in READWRITE mode, and it tries to create a
table. If it's not your own DB, open it in READONLY mode.

If you mean compressing resources, the only thing I've seen used
is changing the extension. You might want to check the source
for details. BTW, are your resources that big? Why not just return
them as byte blobs?

[android-developers] Re: SurfaceHolder.Callback.surfaceCreated not being triggered when surface is re-created

[Thomas Fjellstrom]

So I've managed to fix that particular problem. I'm not sure exactly
what fixed it, but I assume it was a result of a couple different
problems. I needed to set the manifest to only ever launch one
instance at a time (I was seeing more than one activity object be
created which messed things up). And I can't remember the second issue
at the moment for some reason. I fixed up a lot of different issues
trying to figure things out. It's not locking up anymore or waiting
for an event that never comes, but on a resume, its not rendering
anything any more. I am completely re-creating the SurfaceView and the
GL ES context, and surface, with the same code that creates it the
first time. things should be identical, but all I get is a black
screen (instead of the white that I'm clearing it to). I'm getting
input just fine, the rendering thread isn't locked up or anything, but
nothing will draw once the app is restarted.

Anyone have any idea what would cause this?

[Raghav Sood]

I'd say that your error is coming from one of lines 74, 30, 28 or 88. At
least that's what the LogCat says. If you look closer, you will notice that
your prepare() method has failed to work and has given you an exception.

[android-developers] Alarm manager problem

[Hassy]

I'm creating an alarm application and I already created the basic
alarm activity
and receiver class.now I want to repeat the alarm on specific day of
week.

I set DAY_OF_WEEK to 1 to set the alarm repeat on sunday but it
doesn't work.

  Calendar calendar = Calendar.getInstance()
  calendar.set(calendar.DAY_OF_WEEK, 1);
  calendar.set(calendar.HOUR_OF_DAY, sHour);
  calendar.set(calendar.MINUTE, sMin);
  calendar.set(calendar.SECOND, 0);
  calendar.set(calendar.MILLISECOND, 0);

Please tell me how to set the alam on specific day.


Thank you
Hassy

For your own devices, you can decline to install them.

For other people's devices, no, this is not possible.

[android-developers] RectF: float parameters in pixelated canvas???

[John Goche]

Hello,

Can someone explain to me how come there is a RectF class that
takes float parameters when the pixel coordinates take integer values?
How can I draw a pixel at location (3.5,8.777) for instance instead of
at location (3,7). Does this just make sense because of antialiasing?

Thanks for clarification on this subtle issue
and why things have been designed this way in the Canvas related API,

Regards,

John Goche

[android-developers] How to create a bitmap from binary data?

[Vincent]

Hi,

I want to create images from binary data.

e.g.
If the binary data is：

0110 1110 0011 1010
1000 0001 1011  1100
0110 1101   
0100 0011 1001 0011


which is store in 4*4 bytes
{
6 14  3  10
8  1  11 12
6 13 15  0
4  3   9   3
}

I want to create a image(might be bitmap) from the binary data,

if 1, draw a black pixel, if 0, draw a white pixel
so the image would be
 .. ...   ... .
.  .. 
 .. .. .
 ....  .  ..

And I will receive new data and refresh the image frequently.

Could you give me some hints/suggestions?

Re: [android-developers] Alarm manager problem

[Kostya Vasilyev]

If the current day of week is > Sunday, your code moves the calendar
back in time, to most recent Sunday before now.

Add a check for this case, and move the calendar forward one week if needed.

Fractional coordinates are normally used for rendering with sub-pixel
accuracy.  I'm not as familiar with Canvas because I mostly use GL but
I would assume that would be the reason.

There are multiple ways of implementing sub-pixel accurate rendering
but one common usage would be, if a fractional-coordinates primitive
only covers say a quarter of a pixel then that pixel would be filled
with the colour of the primitive with alpha of 0.25.

In my experience this doesn't often matter much for static renderings
but can make your animations look much smoother (depending on context
however).

Do a bunch of other smaller apps that will help teach you what you need to
know to do this.
If you're "new to android" and have to ask how to do what vaguely sounds
like a major task, you're asking for trouble.

[android-developers] Re: getString in a class with no context <- Runtime Error Resource Not Found

[Streets Of Boston]

It's great you got it to work.
But why do you need a separate class (LanguagePack) to get localized 
strings/resources?

In a method of your activity or another context, you could just do: 
getString(R.string.some_string)?

If you want to access localized resources/strings in code that does not 
have a Context readily available, you could create a static singleton of 
your LanguagePack class in the Application object of your app:

public class MyApp extends Application {
  private static LanguagePack myLanguagePack = null;

  ...
  ...

  public LanguagePack getLanguagePack() {
if (myLanguagePack == null) {
  myLanguagePack = new LanguagePack(this);
}
return myLanguagePack;
  }
  ...
  ... 
}


public class LanguagePack {
  private final Context context;
  public LanguagePack(Context context) {
this.context = context.getApplicationContext();
  }

  public String getString(int resID) {
return context.getString(resID);
  }
  ...
  ...
}

And everywhere in your code, you could do 
MyApp.getLanguagePack().getString(R.string.some_string);

[android-developers] Re: list actvity is scrolling

[Streets Of Boston]

Don't use a ListActivity. You only have a small and fixed amount of 
elements (8). Use a regular Activity with a layout that has a vertical 
LinearLayout or a TableLayout as the top element. These two don't scroll.

[android-developers] Re: Unique ID, but not IMEI, IMSI, MAC, AndroidID

[Streets Of Boston]

http://android-developers.blogspot.com/2011/03/identifying-app-installations.html
This link suggests and advises identifying accounts, not specific devices.

However, sometimes you can't get around it. E.g. if you have an app that 
publishes digital content under DRM, you usually have to be able to 
identify individual devices.

This is what we do at my company:


   1. First, try to read one that you have saved in the last step of this 
   procedure. If found, return this one.
   2. Read the telephony id.
   This will work for every phone and tablet with a SIM card and such. 
   Since most Android devices that have Android 2.3 or lower are phones, you 
   have covered a big chunk of your install base.
   If available, use this one. Save it somewhere for point (1.)
   3. Read the Serial number (android.osb.Build.SERIAL)
   This one is only available on 2.3x devices and higher. This means you'd 
   have to use java reflection to get at it if your app must run on Android 
   2.2 or lower.
   If available, use this one. Save it somewhere for point  (1.)
   4. Now you have covered a laaarge chunk of your install-base. 100% of 
   all devices running 2.3x and higher. The only devices that are still can be 
   problematic are Android 2.2. (or lower) devices that are WiFi only:
   5. Read the MAC address of the device
   Since the device is WiFi only, it is their only way to get a 
   data-connection and they just downloaded your app: It is likely that the 
   WiFi is enabled and querying the MAC address very likely succeeds.
   If available, use this one. Save it somewhere for point  (1.)
   6. If everything else fails, generate a Random number/string and use 
   this as your unique-id.
   Save it somewhere for point  (1.)
   
I think this will cover 99.% of your install base. However, it is not 
full-proof. This means that you'd have to design a way to allow the users 
to reset their device-id on your servers, either through some online form 
or through customer service.

[android-developers] Can the LVL check for Paid app be done from my free app ?

[androidmediadeveloper]

I have a Free app with pro features "locked". I also have a paid app
that is basically a stub, an "unlocker". My question is this, can I
run the LVL check to see if user has purchased the unlocker/stub app
from inside of my free app ? It'd be great if this were possible, but
from my experiments until now, isnt the case.

Any advice ? thoughts ?

Thanks!

Re: [android-developers] Re: Unique ID, but not IMEI, IMSI, MAC, AndroidID

[Mark Murphy]

Do you use any sort of a naming convention, so you can identify what's
what for later comparison purposes? I'm thinking something a bit along
the lines of URL schemes (imsi:... or even imsi-v10:... for an IMSI
reported by API Level 10, where the ... is the actual IMSI value).

For example, it may be that an upgrade to the OS changes which of the
rules fires for that device, because they added support for something
they didn't have earlier.

[android-developers] ICS Hardware Acceleration crash

[webmonkey]

In my AndroidManifest.xml I have:



And the Application and Activities all have
android:hardwareAccelerated="false"

So the app should not be hardware accelerated. But in the Android
Developer console I am getting the following crash report from Galaxy
Nexus users with ICS:

I have never seen anything like this in nearly 3,000,000 installs of our

Re: [android-developers] Re: Unique ID, but not IMEI, IMSI, MAC, AndroidID

[Streets Of Boston]

We use the generated device-id for DRM purposes. The generated device-id is 
not used as-is. The DRM code creates encrypts it and creates a hash. The 
hash is used for identifying the device on the DRM server.

It is true that an upgrade from 2.2. to 2.3 can trigger a different result 
if the device-id calculation is called again. This would happen if the user 
upgrades the device to 2.3 and 'clears the data' of our app. 

There are also other ways to have the device-id generate a different 
calculation if the user chooses to 'clear data' of our app later (e.g. on a 
WiFi only device running 2.2: download our app, never open it, then open it 
for the first time in airplane mode (by accident), clear data and then open 
it again at some later point with WiFi enabled). 

These two scenarios are possible, although they are very unlikely. We have 
customer support to deal with this issue (when the user finds he or she 
can't read a book due to a device limit being reached incorrectly).

Re: [android-developers] Re: Unique ID, but not IMEI, IMSI, MAC, AndroidID

[lbendlin]

The vast majority of our support issues is from users that have reflashed 
the ROM on their device which results in a different Android_ID more often 
than not. We also decided to use the fallback scenarios of either IMEI or 
MAC address. (can't use the fancy 2.3 stuff as most users are still on 2.2 
and lower)

Re: [android-developers] Re: Unique ID, but not IMEI, IMSI, MAC, AndroidID

[Raghav Sood]

In my apps, I assign the user a username, and then generate a UUID (v4) and
associate it with the user name. That way I can maintain it across
installs, as long as the user uses the same account,

Thanks

That's probably a problem. Take that out and change your constructor to

or

In the first post, the author describes how he ended up with an app
having a different user ID than the app data directory.

@John Coryat : If you read the original post in this thread and his

[android-developers] Gravity virtual sensor source code

[markus]

Hi all!

Now that Ice Cream Sandwich is out, I thought I'd have a look at how
the "virtual" sensors have their data calculated, in particular
TYPE_GRAVITY. Of course it will involve data from some or all of the
real sensors (accelerometer, gyroscope, and magnetic field), but I've
read somewhere (can't find where just now) that from Android 4 ICS,
the virtual sensors, and TYPE_GRAVITY in particular, will be more
accurate, because they involve the gyroscope, if it's available in
the
phone.

I've got the Android 4 source code downloaded, but I can't find the
place where this data is calculated. It's not in the Java code, as
far
as I can tell, so it must be in native code somewhere. I'm new to
looking at the Android source code, so maybe someone could point me
in
the right direction?

Thank you very much!

[android-developers] Re: Can the LVL check for Paid app be done from my free app ?

[b0b]

Yes this is doable if both app have  the same userId

You can implement a remote service in the unlocker paid app that check the 
license.
Then your free app invoke binds to that remote service to do the check.

If both of your apps share the same android:sharedUserId  you're not forced 
to make the service public.
If you don't have already have set a android:sharedUserId don't change it 
afterwards or it will cause problems (file permissions).

[android-developers] Re: ICS Hardware Acceleration crash

[webmonkey]

Thanks Romain

Anyway to force if off from the app in code? Or how to detect it so
that I can display a message to the user?

I see now that there are some websites that advise people to turn it
on because it makes everything run smoother. I don't think people
realize that not all things can be hardware accelerated. Unfortunately
I have no way of responding to these users who report this issue.

Got any links? At least we can work on trying to get these posts
updated, particularly if there's no SDK means of telling Android "no
means no" when it comes to the Force GPU setting (and I see nothing in
the SDK that looks promising).

[android-developers] Re: Can the LVL check for Paid app be done from my free app ?

[androidmediadeveloper]

sorry, not clear. the free app can check if the paid app was
purchased ? it is the same publisher.

also, seems like i can use the android:sharedUserId and write the
license into shared prefs from one app and have the other read from
it. Is this a security issue ?

thanks

Re: [android-developers] Re: Can the LVL check for Paid app be done from my free app ?

[Kostya Vasilyev]

Let the free app (main) ask the paid app (the unlocker) run the LVL
check and report results using any of the available inter-application
communication options available on Android.

As far as security goes - encrypting / signing the communication is
one option, signing both apps with the same key and using a
signature-protected permission is another.

[android-developers] Re: User cannot install an update

[John Gaby]

Thanks for the suggestions.  I had the user try taking out the battery
but it didn't help (I HAD previously had him reboot his phone which
didn't work either).  I am beginning to think that there is something
screwed up with the permissions as you suggest.  I have actually had a
similar problem on my HTC Hero phone running 2.1 (he is running 2.2).
It gets into a state where I can no longer install my app and it
clearly appears to be a permissions problem (I can't remember the
exact message, but it fails to install something complaining that the
folder doesn't exist).  I have had this happen a number of times and
it usually occurs when I have installed a debug signed apk, un-
installed and then tried to install a signed apk.  However my user has
only ever had properly signed apks.

Ultimately the only way I was able to get it to work again on my HERO
was to reset the entire phone to the factory settings (which deletes
everything), which is not something that my user is wanting to do.

Re: [android-developers] Re: ICS Hardware Acceleration crash

[Romain Guy]

This setting is unfortunately a double-edged sword, it was intended for
developers so they could easily test their application with hardware
acceleration turned on.

You can easily check whether your app is hardware accelerated on startup
and warn the user it's not supported.

[android-developers] Re: ICS Hardware Acceleration crash

[webmonkey]

http://www.theverge.com/2011/12/1/2604136/apps-which-crash-on-galaxy-nexus-when-force-gpu-rendering-is-on

The first comment there is:

"I can only surmise that if the app crashes then the developer MAY
have deviated from the official API and not followed proper
programming practices."

Which is of course incorrect.

It is a partial repost of:

http://forum.xda-developers.com/showthread.php?t=1372007

Where some people do actually suggest to leave it off but they say
that they should wait until the developer updates it for ICS. But for
some apps Hardware Acceleration is never going to work.

Then there is:

http://www.slashgear.com/android-4-0-ics-demo-facial-recognition-battery-life-gpu-rendering-and-more-18196674/

Which says:

"You can turn this option off, effectively, by heading to your
Settings, then to your Developers options, then scrolling down and
tapping the “Force GPU Rendering” option. Though why you’d want to do
that, I do not know, because with this option ON, all of your apps
will run more efficiently."

[android-developers] Re: User cannot install an update

[John Coryat]

You'll have to decide what level of support you want to offer. For me, once 
I've determined it isn't a problem with the app, the user has to look 
elsewhere for support. I can't help solve problems with the countless 
versions of Android/carrier/manufacturer OS's and devices. I'd rather spend 
my time staring off into empty space than do that.

If you want to be 100% support for any problem a user encounters, that's 
strictly up to you but if your app ever gets popular, then you'll be 
swamped. Better to send them to Android support and let them deal with it.

-John Coryat

@martin - I pasted the text I send to users, it wasn't modified to fit the 
poster's experience already. I have found this text to either solve all 
these problems or send the user to a place where they should seek help. 
That's why I posted it.

I interpreted the setting as an aggressive move to make developers
update their apps for ICS. Of course users are going to check a box
marked "Acceleration", especially the first wave of ICS users, Galaxy
Nexus early-adopters or the CM9-alpha crowd.

Also it appears that view.setLayerType(View.LAYER_TYPE_SOFTWARE,
null); still works as intended.

[android-developers] Re: Mobile app discovery

[Jose_GD]

Kenneth, I think you are putting discoverability with testability in the 
same bag. Or have misunderstood you?

Discoverability is the real big deal IMO, a very difficult problem to solve.
Testability perhaps can be solved (at least partially) if Google helps us 
with more flexibility in the buying process, i.e. extending the 15 minute 
time to get a refund por apps users don't want to keep. Or maybe if we have 
some kind of trial mechanism so we don't resort to free - paid apps when we 
don't want to.

Best regards,

José

[android-developers] customer retention

[bob]

I'm having problems with customer retention.  Basically, they download
an app, fiddle around, and leave, I think.  Is there any canned
solution for getting them to sign up for an e-mail list like
mailchimp?  I want to be able to tell them about new products.

[John Gaby]

You are, of course, correct.  I just wanted to understand what is
happening here so that I can determine whether it is my fault or not,
and whether I am going to have others that have this problem.  The
reality is that for every person that takes the time to report a
problem there are probably dozens (or hundreds?) who don't bother.

[android-developers] Re: User cannot install an update

[John Coryat]

That's pretty simple. If they have problems with the installing, updating, 
launching, downloading, uninstalling or (my favorite) the icon has 
disappeared, it's not your problem, it's an Android issue. 99.9% of those 
problems can be simply solved by rebooting or by uninstalling and 
reinstalling.  The rest are going to be oddities that affect only a very 
few and unless you have the actual device in your hands, probably 
unsolvable.

Re: [android-developers] Why doesn't layout_alignCenterInParent work?

[Christopher Van Kirk]

I struggled with this for a few hours then gave up on it. Apparently 
people have been asking this question for several years without a 
meaningful solution. I ended up using the much-maligned nested linear 
layouts approach instead.


Anyway, the issue wasn't related to height, but width. I'm fine with the 
grid view scrolling vertically, but when I specify that it has only 3 
columns, I want to be able to center those three in its parent, 
otherwise it looks awful. Seems like there's no good way to do that.


Next, I don't want to give it fixed dimensions because the range of 
devices causes the stuff I put inside it to grow and shrink with screen 
sizes. As far as I'm aware, there's no way to specify a percentage in 
either dimension.


Anyway, the problem is solved for the moment, although I'm not terribly 
excited about how I had to do it.

Try it with a GridView with fixed dimensions and see what happens.

My problem is that I can't find an explanation for the use of the

I would agree with John that this is not worth your time as a support

Otherwise, factory reset :(.

[android-developers] Re: Mobile app discovery

[klewelling]

I want a service separate from testing. Running an app without
installing reduces friction, there is no steps getting in the way of
using the app. Your comment about trials is exactly the type of
feedback I want. The nature of the solution I had in mind lends itself
to trials or timelimits in apps. This would encourage users to try an
app and if they like it to buy it from the android market.

Thanks for the feedback

It's certainly not part of the Android SDK. AFAIK, that exclamation
point will be ignored.

Note that the STATUS_BAR permission is unavailable to standard SDK applications.

[android-developers] Re: how to retrieve connected bluetooth headset battery strength

[lbendlin]

let me copy and paste that for you

/**
* Get battery usage hint for Bluetooth Headset service.
* This is a monotonically increasing integer. Wraps to 0 at
* Integer.MAX_INT, and at boot.
* Current implementation returns the number of AT commands handled since
* boot. This is a good indicator for spammy headset/handsfree units that
* can keep the device awake by polling for cellular status updates. As a
* rule of thumb, each AT command prevents the CPU from sleeping for 500 ms
* @return monotonically increasing battery usage hint, or a negative error

So the short answer would be "No".

Thanks for all your help, the user does not have root access and is
