Re: [android-developers] Share data between an activity and an event listener (separate class file)

[StSch]

I maybe should have said:
Can I access attributes/member variables of my activity in my event 
listener? That is: Manipulate the date in my listener and have the updated 
data in my activity?

Depends on which app/process u were monitoring. If you monitor the zygote

[android-developers] Re: C2DM is deprecated from june26th

[Mek Rama]

okay, I see the 
https://developers.google.com/android/c2dm/ 

*Important:* C2DM has been officially deprecated as of June 26, 2012. At 
that time C2DM stopped accepting new users and quota requests. C2DM has 
been replaced byGoogle Cloud Messaging for 
Android (GCM). 
The C2DM service will continue to be maintained in the short term, but 
developers must use GCM for new development. We also encourage developers 
to move existing C2DM applications to GCM to take advantage of GCM 
features. See the C2DM-to-GCM 
Migration document 
for more information

That is true. Its still the same. But then as a developer (assuming u have 
the N1), would'nt getting power consumption details on one model still give 
u a fair and reasonably consistent view of how it would perform on most 
models ? If the intent is to understand the consumption pattern of ones 
application, this is reasonably good enough right ?

Looks like the Trepn profiler is currently being redesigned and is not 
available 
(https://developer.qualcomm.com/mobile-development/development-devices/trepn-profiler),
 
but then as u mentioned it needs to be used with their expensive MDP 
devices.

[android-developers] How do I set up the project in the Android site's “Managing the Activity Lifecycle” training exercise?

[Jason Hsu]

 

I'm trying to implement the project in the Android site's "Managing the 
Activity Lifecycle" training exercise at 
http://developer.android.com/training/basics/activity-lifecycle/index.html .

The instructions don't say how to set it up. A *.zip file is provided, but 
I can't figure out how to get it to work. No matter what I do, there are 
errors that keep the project from running.

What is the proper procedure for getting this project to work?

Yes, I have not only completed the Building Your First App tutorial but 
also published an app on Google Play. (It's a fun little app called Upgrade 
Your Cereal.)  So I have experience in starting and completing projects, 
but this is the first time I've tried to start a project SOLELY from a 
*.zip file.

[android-developers] Re: How to prevent the layout from getting reset when the screen orientation changes?

[Nobu Games]

As someone in your other thread already mentioned: you need to keep track 
of these layout changes you do and save this information in the 
onSaveInstanceState method. You could save a boolean value for example that 
indicates that "Button 2" has been added. In onCreate you need to read the 
savedInstanceState Bundle and check whether that "Button 2" flag is 
present. If that is the case you have to re-create Button 2 then.

Some pseudo code:

onSaveInstanceState(Bundle outState) {
outState.putBoolean("button2", true);
}

onCreate(Bundle savedInstanceState) {
if(savedInstanceState != null) {
if(savedInstanceState.getBoolean("button2")) {
 // Add button 2 to your layout
}
}
}

If that email says that your account has been suspended because of previous 
account violations, then it has something to do with you and your account 
and not with the person you bought that app from, methinks.

Was it the first time that you bought an existing app and uploaded it as 
your own?

Judging this piece of code you are a complete beginner and may want to pick 
up some basic programming classes / books / tutorials. This group is not 
the right place for that.

Anyway. You have syntax errors in it (missing commas between 
"Enter...Value" and 3000), the method "Toast.makeTest" does not exist. It 
should be "Toast.makeText" instead. The number 3000 should be either 
Toast.LENGTH_SHORT or Toast.LENGTH_LONG and in the end you need to call the 
show() method on the resulting Toast object which is returned by 
Toast.makeText.

Re: [android-developers] Re: Trying to set toggleButton at right of text view

[Justin Anderson]

Why do you have so many LinearLayouts inyour XML?  You don't need to wrap
your TextView or your ToggleButton in a LinearLayout.  That being said, the
problem is that you are declaring your LinearLayout to be VERTICAL...
Hence, the TextView would be added, and then the ToggleButton would be
added VERTICALLY beneath the TextView...

Have you tried something simple like this?

http://schemas.android.com/apk/res/android";
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:padding="4px">

Re: [android-developers] Using Implicent Intent to open system application

[Justin Anderson]

You already asked this question and you received an answer... What more do
you want?  The problem is that nothing is calling your LaunchComponent()
method...

As you were told before, override the onCreate() method and call your
LaunchComponent() method from there.

Re: [android-developers] GoogleCalendarSyncAdapter - any limit on syncing calendar events from google server

[Michael Chan]

Hi,

The GoogleCalendarSyncAdapter's sync window is currently one month
back and one year forward. It won't sync any event that ended earlier
than a month ago.

GoogleCalendarSyncAdapter does not have a limit on the number of
event. Of course, there storage limits and the database will be slow
and unusable at some point.

Thanks,
Mike

You've defined a method, "LaunchComponent" ... and that's it. How do you
expect it to get called?

Override onCreate(), which is called when your app is launched, and call
your method from there.

Re: [android-developers] Re: AccountManager undocumented exception returns "unknown authTokenType"

[Sandeep Dhameshia]

thanks mate for reply.

am using nexus device, so shouldn't be that issue. and I see it not that
frequently. bit strange but it's happening at particular time in a day, say
between 18-21IST. I know it's weird but I've observed this. rest of the
times it's as expected!!

[android-developers] I really Need help guys

[Jaison Brooks]

Ok, im feeling really stupid right now, for some reason i cannot figure out 
how to create just a signal application that when the user clicks the icon 
from the home screen, it opens a different application. For instance, you 
click on my app and it takes you to your email icon, or settings or 
something along those lines.

Here is some code i got so far, but its not doing anything when i open the 
application, just showing blank white screen with the label of my 
application.

JAVA File

package com.xxx.xxx.xxx;

import android.app.Activity;
import android.content.Intent;
import android.content.pm.
PackageManager;


public class MainActivity extends Activity {

public void  LaunchComponent (String packageName, String name){
Intent task = new
Intent(Intent.ACTION_MAIN);
PackageManager manager =
getPackageManager ();
task = manager.getLaunchIntentForPackage("com.xxx.xxx.xxx");
task.addCategory(Intent.CATEGORY_HOME);
startActivity(task);

}
}

i do NOT have a layout file, i didnt think i would need one, since i am not 
creating a UI at all.
Any recommendations would help alot, i've tried a few links, and i just 
cannot get something to compile right.

Re: [android-developers] Share data between an activity and an event listener (separate class file)

[Justin Anderson]

This is a basic java question, not related to Android in any way...

To do that you can create a constructor that takes as parameters the data
you want you're listener to have access to.  Alternatively you can add
getters/setters to add that data you want separately. ..

The difference is one is add in onCreate, which is called again when the
Activity is recreated, and the other is called dynamically on click of a
button, which of course does not get called again.

Unfortunately, that's how it's done. Either that or handle the
configuration changes yourself, which is a whole other can of worms.

What I would do is have a business model object that describes your UI.
Instead of modifying your UI on clicking a button, you update your model
and build your UI off of that. When you change configuration, persist the
model (as a Bundle, as a static, whatever) and recreate your UI from it as
necessary.

Re: [android-developers] Preferred way to prevent the layout (example included) from getting reset when the screen orientation changes?

[StSch]

I add one button programatically to my layout and would have expected 
Android to keep the layout, especially since the documentation of the 
onSaveInstanceState()-method says:

The default implementation takes care of most of the UI per-instance state 
for you by calling onSaveInstanceState() on each view in the hierarchy that 
has an id, and by saving the id of the currently focused view (all of which 
is restored by the default implementation of 
onRestoreInstanceState(Bundle)).

And in the source code of one of the examples I find this comment:

The system takes care of saving a view's state as long as an id has been 
assigned to the view.

My layout changes heavily in the event listeners and it would be very 
time-consuming and tiring to save the state and restore it again.

[android-developers] progress bar too small

[bob]

I'm trying to make a large indeterminate progress bar for my tablet.  When 
I do this

style="?android:attr/progressBarStyleLarge"

it still is fairly small.  If I force it to be larger, it gets real grainy. 
 Is there a way to get a big progress bar that isn't all grainy?

Everything is intended for the online database. The local one is temporary
storage in case an internet connection is unavailable. The best solution
I've come up with so far is to use string values in the local database, and
process them into credits on the server. So in the local database I can
have a string like "CreditA" which corresponds to 100 credits on the
server. That way, even a rooted user can only boost their credits by a limit

Thanks

You do not have to sign up on your Web site to make in-app purchases,
AFAIK. If you choose to make this a requirement, that is your
decision, but then please don't complain when users get frustrated

People who root their phones and elect to tinker with the innards of
your database perhaps won't make in-app purchases, or will make one
(to seed the database) and that's it. Rooted users should represent a
tiny percentage of your user base, so this should represent a tiny
loss of revenue. Personally, I think you have already spent more time
worrying about it than it is worth, but that's just me. Or, as
Kristopher pointed out, if you can detect this condition during game
play, nuke 'em from orbit.

So store the currency in an online database?  Or use some form of
encryption... Or understand that pretty much nobody will do this, and
if they do, simply boot their account from your system.

Wow. Mark Murphy hasn't tried something related to Android :-) Anyways,
since all of my items are managed items, I can verify with Google if the
user has purchased them or not, but the local database might also have in
app currency values. A rooted user could exploit this to give himself

Re: [android-developers] Android ICS VpnService

[Robert Greenwalt]

You say you found some applications "that use VpnService, but without using
a remote server".  Are the providing VPN capabilities?  i don't think so.
 Yes, you can create a client-side VpnService without network connectivity,
but it's clearly not providing a vpn.

I think if you want to create a real VPN and a custom VpnService you should
educate yourself on what a
VPNis.

Not really. Moreover, other than the in-app purchases, it should not

yours. And while I have not implemented in-app purchasing, I would

I think this really depends on how you want your menus to look and/or
whether you're familiar with developing using Android widgets. If you
want your game to have its own look & feel and/or you aren't familiar
with widgets it's probably easier to use a single activity and use
similar methods to what your game screen uses to draw things and respond
to input. This is the approach used in the book Beginning Android Games.
The activity owns an object implementing a Screen interface to render
the screen and respond to input, so by replacing the Screen object you
can display all sorts of different screens. I think that's a better
design than having an enum and switch for different states.

If you'd prefer your menu screens to use familiar Android widgets then
use separate activities.

[android-developers] Remote database for users' game data - Best Practices

[Raghav Sood]

Hi all,

I'm working on a game. My game has a bunch of things like In app purchases,
in game credits, unlocked content etc. To allow users to move their
progress and purchases across devices, I've decided to have them sign up
for an account at the beginning. This account will store all of their data.
Additionally, this account can be used by the same user with my future
games as well. Now I had a few questions about the best practices when
using a system like this. Here's what I've come up with so far. If
something can be done better, or I've left out something that'll help me,
please tell me.


   - User signs up at first run. Email is verified etc.
   - User account is stored online in Database A, so that I can use the
   accounts for future games
   - After this, purchase information etc is stored in Database B, which is
   different on a game to game basis.
   - In case internet is not available when the user does something that
   needs to be saved, it is stored to a local database, which is synced with
   the online one when an internet connection is found

Potential problems with this approach:

   - Some users may not appreciate having to sign up for an account
   - A rooted user could edit the local database and insert their own data
   to it. Is it possible to prevent/make this difficult?
   - While I have a certification in PHP/MySQL, I'm not too familiar with
   databases on Android.

Is there something I've left out/ignored? Do any of you have a better
approach to solve this problem?

Thanks

Re: [android-developers] may i declare in the AndroidManifest.xml of the test project?

I would *strongly* discourage you from using shared user IDs.  Once you
publish your app like this, you can't change it.  This has lots of subtle
repercussions for your app.  Just please stay away from it.  Definitely do
not use it just for testing.

If the information is good enough to show to the user, it should be good 
enough for
the user to gather up with an app to look at later.  All this hand waving 
about "ever
evolving" and "device specific" just pushes people to re-implement what 
they can
see done by the UI in the AOSP code (which, IMO is worse because it won't be
able to track the evolution/device specific changes.)

Hiding it in dumpsys output or forcing the user to click through menus and 
not exporting
it to the public API looks like either lazyness or some plot to put 
application developers
at a disadvantage if they want to be able to let users have the choice to 
track things in
a way Google may not have thought of.

There are plenty of other APIs that provide "rough estimates" (like 
RunningAppInfo) so
I don't see why there would be an issue with making it public and saying 
"rough estimate"
in the docs.

Anyway, the default implementation of Activity when it gets the back key is
to call finish().  If it is not finishing, you are overriding this behavior

Use a device bolted to the roof of the truck cab then; those have been
on the market for a long time.   Saves the privacy issue since you are
tracking the company asset (the vehicle), saves the reliability issue
since it gets vehicle power and isn't dependent on the employee

Doing it via a customized android build would not be all that

Yes, but only in a customized android installation.  This group is

[android-developers] Re: Need help - hidden GPS monitoring app

[Nobu Games]

You got your answers by programmers who are familiar with the Android SDK 
and platform. What you are requesting is not possible without firmware 
modifications (which is out of the scope of this group). And I agree with 
Daniel's remarks. The idea itself is a bit flawed. What happens if there is 
no data connectivity, or the battery is dying? Or the user just turns off 
the device? Or the user is making a phone call (I don't think that you can 
have data connectivity and phone calls simultaneously, but I'm not sure 
about that). In the end of the day your customer / the employer has to put 
a bit of trust into their employees for making that big brother system work:

   1. The employees need to know and agree on that they are spied on
   2. The employees agree not to temper with that app, neither are they 
   allowed to stop it nor are they allowed to temper with its data storage or 
   functionality
   3. The employees agree to keep the phone and GPS feature turned on as 
   long as possible

Your app could still cache the collected data and upload it to the server 
as soon as connectivity is available. If there are anomalies this can be 
figured out on the server side by the end of the day and traced back to a 
particular employee.

Furthermore you could make your spy app the default home launcher app, just 
to make sure it gets started as first app and every time the home button 
gets pressed. Still: the user could revert back to the default home 
launcher.

Only via your own custom firmware, for obvious privacy and security
reasons. Discussion of that is off-topic for this list -- see
http://source.android.com to learn about the Android firmware.

Thanks a  lot for your reply!

So, is there any way to montior all the communication channels between
Android apps inside the devices?
Any existed mechanism or reference or codes?

Thanks a lot.

Well, seeing as you aren't telling us the exact problem, we can't really

Your app can run as root, and the user can still stop the app. The

They can simply uninstall your app. The only way to stop this would be

Yes, for some definitions of "open the 3G/GPRS connection".

[android-developers] Re: Need help - hidden GPS monitoring app

[Mihai Popescu]

First of all: Google's idea about design seems to evade me :)
I didn't see most of your replies.

1. Legal issues
The software (application, service or custom OS) will be used on employee 
handsets. I assume our customer can get them to sign some papers for this, 
it is not really my problem :)
The client is not a seller, it is a large company and its activity involves 
mostly transporting goods throughout the country. The purpose of the 
software is to monitor truck driver location, thus enforcing some policies 
to save money. Can't have a truck driver get paid for telling lies about 
being stuck 2 hours in traffic, while watching TV at home, and getting paid 
for that, right?

2. The custom OS solution
I know this is the best option, but I'm not sure the customer will be 
interested in spending that much money.
Also, I think buying car tracking devices might exceed their budget and 
also cost them some monthly fee for them. They do own over a thousand 
trucks,  and buying GPS trackers for them would go up to 200k, while they 
plan to invest only half of that in software in general, and not only for 
the tracking app.
Besides, this would mean no profit for us :)

3. More questions regarding Android and having the app run in background
Android is based on Linux, so doesn't it have some low-level user 
management? You know, somewhat like a regular Linux distribution.
I am thinking maybe my app/service can run as root, and require root 
permissions to be shut down (maybe password protected?).
Also, I assume that services are the only type of sotware capable of 
starting on phone power-up, so probably this will be the best solution.
The next obvious question would be: can I prevent the user from changing 
the service start-up settings?
And of course: can the service open the 3G/GPRS connection at any time 
without generating additional dialogs?

Thank you!

[android-developers] IAP Error RESULT_SERVICE_UNAVAILABLE - Unexpected response code 429

[Joel Martinez]

Strange error that I'm seeing when trying to restore transactions:

06-29 11:57:06.255: E/Volley(16498): [13] BasicNetwork.performRequest: 
Unexpected response code 429 for 
https://android.clients.google.com/vending/api/ApiRequest
06-29 11:57:06.265: E/Finsky(16498): [1] 
NotifyingErrorListener.onErrorResponse: Server error on 
InAppPurchaseInformationRequest: com.android.volley.ServerError

which comes back in response to the request to RESTORE_TRANSACTIONS. 
According to some other threads I've come across on stack overflow, this 
seems related to potentially sending too many restore requests, which could 
potentially happen during development. 

Is there any definitive documentation about this behavior/response? How 
does one recover from receiving this error after it has been encountered 
... I first noticed this yesterday, and then when I tried it again this 
morning am still receiving it. 

Question was also posted on SO (albeit in an earlier form, before I had 
more info about the problem):

[android-developers] Android Device Emulator

[Zan]

Hello all,

Just developed a fast application in Adobe Flash CS5, and I published
it as an "Emulator Release" for Android 2.2. Adobe compiled & created
the .apk, and also installed on the emulator, but when I start the
application on the emulator, it seems nothing happens but a black
blank screen comes up. I already installed AIR.apk on the emulator,
and tried Android 2.3.3 which's not worked neither.
Could you give me some advice please?

Thank you,
~Zan.

[android-developers] Re: Process 8769 terminated by signal (7)

[Andrei Buneyeu]

I had very similar issue - ffmpeg caused crash of my app by signal 7 
(SIGBUS) after decoding several hundreds of frames. It was not very device 
specific - on some devices app crashed more often, on other less often.

It was very incomprehensible issue for me cause it could happen at any time 
of video encoding/decoding and I couldn't find any conditions that causes 
failures.
But I recompiled ffmpeg with `-malign-double` flag according to this useful 
article:
http://software.intel.com/en-us/blogs/2011/08/18/understanding-x86-vs-arm-memory-alignment-on-android/.
 
And it helped! So my full "configure" line is (of course not all of these 
flags are useful for you):

> ./configure --target-os=linux --cross-prefix=arm-linux-androideabi-
> --disable-asm --arch=arm --cpu=cortex-a9 --sysroot=${SYSROOT} 
--enable-neon --disable-avdevice --enable-decoder=mjpeg 
--enable-demuxer=mjpeg --enable-parser=mjpeg --enable-demuxer=image2

-L../android-libs -Wl,-rpath-link,../android-libs' 
--extra-cxxflags='-Wno-multichar -malign-double -fno-exceptions -fno-rtti'

Hope it'll help you.

[android-developers] adb, ant and emulator devices

[kosie99]

When I start an emulator, I see that adb has 2 devices listed, one that 
look something like this STOJKDHY and another one that has a name like 
emulator-5554. When I do a ant install, it tells me that there are more 
that one emulator running and it fails. I then need to specify 
emulator-5554 explicitly. Is this something new, because I never had to do 
it before? Or am I doing something wrong (most probable cause ;))

I actually had the exact same question.  The original post, the question,

[android-developers] How to use gwtp dispatch actions on android

[Bery]

Hello.

This is the link from the stackoverflow question if you would like to 
answer there also: 
http://stackoverflow.com/questions/11151996/how-to-use-dispatch-actions-on-android/11152042#comment14622740_11152042

I am working on a project hosted on AppEngine, and for the browser client I 
am using the GWTP platform which implies using GIN (on the client) and 
GUICE on the server. Also, it uses Models, presenters, actions and events.

I am thinking of also writing an android client for the service but I don't 
know how to start because I don't know how to connect and exchange data 
with the webservice. I would have to use Actions and Action Handlers ( 
http://code.google.com/p/gwt-platform/wiki/GettingStartedDispatch ) which I 
use for the browser client. From Android I only know how to do it with RPC, 
and I can't make the connection, I don't know how to map classes from the 
device to the server.

For example, by using GWTP, if on the browser client I want to do something 
on the server, I implement an Action class, an ActionResult class ( both on 
the client ) and an ActionHandler class (on the server). To dispatch an 
action, I use the DispatchAsync interface and to get the result I use 
AsyncCallback.

Action (on the client ) - SendRoadNotification.java :

public class SendRoadNotification extends
ActionImpl {

private RoadNotification roadNot;



@SuppressWarnings("unused")
private SendRoadNotification() {
// For serialization only
}

public SendRoadNotification(RoadNotification roadNot) {
this.roadNot = roadNot;
}

public RoadNotification getRoadNot() {
return roadNot;
}
}

ActionResult (on the client ) -- SendRoadNotfifcationResult.java :

public class SendRoadNotificationResult implements Result {

private RoadNotification roadNot;

@SuppressWarnings("unused")
private SendRoadNotificationResult() {
// For serialization only
}

public SendRoadNotificationResult(RoadNotification roadNot) {
this.roadNot = roadNot;
}

public RoadNotification getRoadNot() {
return roadNot;
}
}

ActionHandler ( on the server ) -- SendRoadNotificationActionHandler.java :

public class SendRoadNotificationActionHandler implements
ActionHandler {

static DataStore ds = DataStore.getDatastoreService();

@Inject
public SendRoadNotificationActionHandler() {
}

@Override
public SendRoadNotificationResult execute(SendRoadNotification action,
ExecutionContext context) throws ActionException {

//Here I am doing something with that action
}

@Override
public void undo(SendRoadNotification action,
SendRoadNotificationResult result, ExecutionContext context)
throws ActionException {
}

@Override
public Class getActionType() {
return SendRoadNotification.class;
}
}

The way I use those, is:

SendRoadNotification action = new SendRoadNotification(rn);
dispatchAsync.execute(action, sendRoadNotifCallback);

And the callback:

AsyncCallback sendRoadNotifCallback = new 
AsyncCallback() {

@Override
public void onSuccess(SendRoadNotificationResult result) {


}

@Override
public void onFailure(Throwable caught) {
Window.alert("Something went wrong");

}

};

How can I implement this in android ? Can somebody give me an example or 
had this problem before ?

I am using AppEngine sdk 1.6.4, GWT sdk 2.4.0, GWTP plugin for Eclipse and 
GPE plugin for Eclipse.

[android-developers] Activity Feed Within Native Android App

[Xiaoyang]

I am trying to build a feature in an Android app that allows a user to
post some combination of text and images onto a "news feed" that can
be 1) visible to all users or 2) visible to the user's friends (the
user decides this at each posting).

I have tried Google to no avail, so my question is, I guess, where
should I start? (What should I use for the database, etc.)

Thanks everyone.

Re: [android-developers] may i declare in the AndroidManifest.xml of the test project?

[Jagadish Vasarla]

Create a Service with aidl interface which uploads logs to server. Include
your "android.permission.INTERNET" permission  in the service. Call the
Service calls from ur test app. It is just like server and client.

With Regards,
V.Jagadish

[android-developers] Why Galaxy Tab 2 7.0 (GT-P3110) not found in supported device

[Tiger Ng]

Hi,

I am using Galaxy Tab 2 7.0 (GT-P3110) for development.
After I upload app to Google Play, it said "This app is incompatible with 
your Samsung GT-P3110".

Here is my settings in manifest.xml

 



Also I check with google play's support: 
http://support.google.com/googleplay/bin/answer.py?hl=en&answer=1727131#S
they are no GT-P3110 devices ? What is the problem ? I can use Google Play 
in my device to download other apps.
