Unsure, trace based JIT, so optimizes based on what code is actually *used*.

Some of it is mirrored on github, but even if you read dalvik, finding
the answer to this question might take a long time (because it's just
plain complicated to understand the source.)

Re: [android-developers] suspend a Thread

[Kristopher Micinski]

Unrelated to onPause, that's just for UI threads.  (Well,
specifically, Activity and friends (subclasses))

Do a Thread.sleep()?

Handlers, and Timers seem to be good (I'd recommend Handler.)

[android-developers] Re: LVL - Checking licence validity from a server

[Ben]

For anyone else having this problem, the issue was with the response
data.

Signed data comes in looking like this if it's a TEST EMAIL account:-
0|136040138|com.foo.bar|1|ANlOHQOShF3uJUwv3Ql+fbsgEG9FD35Hag==|
123456789012

if it is a genuine MARKET account
0|136040138|com.foo.bar|1|ANlOHQOShF3uJUwv3Ql+fbsgEG9FD35Hag==|
123456789012:GR=10&VT=0987654321>=1234567890

When the signed data is validated, the data after the ':' is stripped,
so trying to re-validate the data will fail in the case of the market
account, and pass in the case of the test email account.

Ben

You don't need to draw the whole Activity over.  If you set a bitmap
into an ImageView, Android will render that after your code completes
its current run and allows the UI thread to process that change.  You
need to put each frame into the ImageView followed by some delay.  You
can use a Handler to schedule delays on the UI thread.

Or you could put it on the sd card, right?  That makes more sense than

If you have to create your sqlite database outside of Android to use
it inside Android, you have to create the android_metadata table that
it would normally create for you.

Re: [android-developers] Re: How do I report a bug to htc?

[Miguel Morales]

You need to use a Lock such as:
http://developer.android.com/reference/java/util/concurrent/locks/ReentrantLock.html
This sounds like a race conditions, as others have pointed out.  These
are usually the hardest to narrow down.

Static variables are not a good idea in general unless you know
exactly what you're doing.

Try adding a lock around your static object, like:

private static Object mMyProtectedVar;
private final Lock mLock = new ReentrantLock();

Then before touching the variable, ALWAYS use the lock like so:

mLock.lock();
mMyProtectedVar.something = something;
mLock.unlock();

Java provides some keywords for making variables and methods thread
safe, although I find a lock to be really clear as to its intended
purpose.

The line of code threw an exception and you didn't catch it, so it
jumped to the finally block.  After that, the caller of this function
would have to handle the exception because you declared this method as
"throws Exception" (which is usually a bad idea unless you really know
what you're doing).  Try taking out the "throws Exception" and
handling exceptions in the method itself.

What do you mean by "fake audio recording"?

You can do real audio recording from the NDK using JNI to instantiate
and operate a java AudioRecord object.  The source code you're looking
at is not part of the exposed NDK API so you are asking for trouble if
you try to dig around in there in your app.

Are you sure you were really using private static final?  Static
finals are initialized when the class loads and will never change as
long as that class remains loaded.  All threads would be seeing the
same value the entire time.

The other code you showed can have a race condition in that first
thread that assigns status may not have reconciled its local copy of
the new Status object by the time the second thread tries to access
it.  You would need to synchronize both accesses or use volatile to
keep them in sync.

You are almost certainly not running into an HTC error.

I figured it out.  It was a combination of not accessing the correct

(hope this helps someone else):


public void parseCharXmlFile(){
Chars myCh;
String nameTag= "";

try {
Resources res = getResources();
int eventType = parser.getEventType();
boolean done = false;

while (eventType != XmlPullParser.END_DOCUMENT && !done 
){
switch (eventType){
case XmlPullParser.START_DOCUMENT:
chars.clear();
break;
case XmlPullParser.START_TAG:
nameTag = parser.getName();
System.out.println("Reading start tag " + 
nameTag);
if (nameTag.equalsIgnoreCase("ch") ) {
myCh = new Chars(' ',0);

myCh.setTheChar(parser.nextText().charAt(1));
}  else if 
(nameTag.equalsIgnoreCase("count")) {

myCh.setCount(Integer.parseInt(parser.nextText()));
}
 break;
case XmlPullParser.END_TAG:
nameTag = parser.getName();
if (nameTag.equalsIgnoreCase("Chars") ){
done = true;
} else if (nameTag.equalsIgnoreCase("ChPair"))
{
chars.add(myCh);
}
break;
}  // event switch end
eventType = parser.next();
} // end while
} catch (XmlPullParserException ex) {

Sure. Toast.makeText(context, int, ...) takes a string resource id as 
its second parameter.


What you want is:

Toast.makeText(context, "The value is: " + String.valueOf(msg.arg1), ... );

Or msg.arg2, or msg.what, depending on what exactly you'd like to log.

And, as a debugging aid, you might as well use logging:

Log.i("MyApp", "The value of x is " + String.valueOf(x));

This will get printed into the logcat, which can be viewed in Eclipse's 
DDMS perspective (or outside: "adb logcat" in your operating system's 
command line window).

[android-developers] Re: LVL and InApp Billing

[Phil H]

The only thing I would say is that, in my recent investigation into
LVL, you can see how many devices are using a single purchased
licence, which may be useful.

[android-developers] Re: LVL, DeviceLimiter and userId

[Phil H]

OK after playing with two different accounts across three different
devices... the userId passed to DeviceLimiter is maintained across
devices and between wipes. So, if a user has purchased an LVL licenced
application, DeviceLimiter will always receive the same userId
string.

Therefore, it is possible to tell how many devices an application is
being used across by using, for example, a cookie type approach.

[android-developers] Inapp billing question

[androidmediadeveloper]

We already have a free app in the market which is doing fairly well.
We now want to offer a newer version of the app, this with the ability
to go Pro via Inapp billing. I've run several tests with the static
requests and they all seem to work well. When I tried to upload the
app to market to test, it does not let me upload with the same package
name and says "you need to upgrade existing app". And, when I try to
see if I can upgrade without publishing the existing app, it has
messaging which says "Clicking 'Save" will make the app live on
Android Market".

I'd like to test the inapp billing piece, not make it live at this
point. I dont want to change package names just to test because it is
a very elaborate process needing sweeping structure and code changes
where there are references to package names.

Any help ?

[android-developers] LVL and InApp Billing

[androidmediadeveloper]

Have noticed several posts on this issue but no specific resolution,
so, trying again. We are going to market with a paid app built using
Google's InApp billing infrastructure. We've secured the purchase
database with all the security best practices and it seems to be
working well. Is there anything specific to gain in terms of security
or performance, or any advantages in general that people see in
additionally implementing the license verification via LVL ?

At this point I am thinking no, but if people have advice to share,
I'd appreciate it and will help us make a better informed decision.

Thanks!

True. However, RAD tools are intended to complement development of
real applications, not serve as a fallback because you don't know the
real development process.  I've got nothing against the use of these
tools for experienced developers, but the point stands:  if you're
learning Android development (or any kind of development) it would be
just plain wrong to recommend a tool other than the official SDK.
This is for multiple reasons: future employment possibilities, a much
larger userbase for the official tools (implies faster response to
questions a newcomer may have), and lots of available source.

So again, nothing against basic4android, but as the first thing you
learn I feel that you would be much better to sticking to the sdk,
possibly supplemented by these tools if they become useful later down
the road.

Perhaps simpler in terms of less overwhelming with respect to general
language features.  But again, I think this is probably because there
is a lot less to their language than java (where in eclipse you have
lots of popups for documentation, test cases, etc..., most of which
many people never use..)

Again, not bad, but not a clear reason why someone wouldn't want to
use eclipse, especially being a CS major you've probably experienced
something very similar before.

Re: [android-developers] NEWBIE needs help with Android Tab Widget tutorial

[Joel Witherspoon]

Chris,

You should only add the  into one activity. Intents are
communication channels between the layout and the code (to put it roughly).
When you have an intent in an activity, that activity is the main
communication point of the app.

Here's an example from the Dashboard Demo at this site:
http://blahti.wordpress.com/2011/03/14/build-dashboard-ui-for-android/. The
application then calls the other activities from within the code.


http://schemas.android.com/apk/res/android";
  package="com.wglxy.example.dash1"
  android:versionCode="1"
  android:versionName="1.0">

[android-developers] Re: hello

[clark]

As Kristopher said, you will be much better off sticking with Java and
the Android SDK.  BASIC is fine for those that don't do a lot of
programming but as a CS major you'll be doing quite a bit and you will
benefit more from using Java than BASIC.  I'm not knocking BASIC, I'm
just letting you know that you will be doing yourself a huge favor by
going the Java/Android SDK route.  It will pay off later on down the
road and you would be doing yourself a disservice by using
Basic4android.


And there you have my $0.02.

[android-developers] Variable instruction counts of Android applications

[Jack Harvard]

Hi,

I find that the same application running on Android has different
instruction counts every time it's run, and the difference in
instruction counts can be 2x or ~10 billion instructions, and I'm
trying to understand the reasons for that?

Obvious reasons might be JIT and JVM, maybe Android browser has any
time dependent code as well? The Android source code tree is down for
some time, I don't have access to the source code.

Thanks,
Jack

Note that Basic4android is much more than a watered down version of
the Android SDK. It is a RAD tool for building Android applications.
Just as an example Basic4android supports many advanced features such
as USB host, SMTP, POP3, home widgets, services, web services and many
more.

The IDE is built from scratch for Android development and is therefore
much simpler than Eclipse.

[android-developers] Re: NEWBIE needs help with Android Tab Widget tutorial

[Studio LFP]

Make sure to re-read the Appwidget section: 
http://developer.android.com/guide/topics/appwidgets/index.html

There is no widget defined in your manifest.

A widget is a  element and needs a few other supporting files in 
the res/xml and res/layout directories.

Also, you are defining them all with:






which is used to make the activity show up in the launcher. You only want to 
use that on the activities you want the users to launch directly.

Check out: 
http://developer.android.com/guide/topics/manifest/manifest-intro.html

You probably want to post more code and the error for people to help you 
resolve the issues.

[android-developers] Re: Always-on GPS: widget or app?

[Studio LFP]

I hoping this was fixed along the way and the issue not updated.  I had to 
drop a part of an internal application for a company because of this bug.

And like lbendlin said, you could just check the last known and see if it 
was recent enough to use.

private static final int TIME_WINDOW = 1; // 10 Second window

LocationManager lmMgr = (LocationManager)getSystemService( 
Context.LOCATION_SERVICE );
Location lLast = lmMgr.getLastKnownLocation( LocationManager.GPS_PROVIDER );

if( System.currentTimeMillis() - lLast.getTime() < TIME_WINDOW )
{
// Use last known. 
}

You can always do this first and if something else is using the GPS you 
could get a good fix fairly quickly.  Just know that this can be VERY old 
and you would want to do proper checking on it.

[Studio LFP]

If your app is crashing, I wouldn't worry about how to keep your 
notifications up after a crash, I would worry about figuring out how to 
prevent the crash.

It's not a good experience for your users if the app is going to crash.

If you want to show us the error and where it is crashing in your code, I'm 
sure someone could help you prevent the crash and eliminate the need for you 
to figure out how to keep a notification up after a crash.

[android-developers] Re: Always-on GPS: widget or app?

[lbendlin]

I haven't seen the issues with concurrent GPS access that you describe.  
nevertheless you may want to anticipate a situation when another program is 
currently actively using the GPS. In such a case you could ask the passive 
provider first, and only if that location is too old or to imprecise then 
you would fire up your own locationlistener.

[android-developers] Re: real time gps tracking

[Studio LFP]

Google has a application like this in most Android phones. Check out Google 
Latitude.

It will give you an idea of how they use their servers to keep up with 
people. It allows you to check-in at places and send faster updates to 
certain people if you want to let them follow you more actively.

[android-developers] Re: Hide few fields of database OR hide a table in the database from being accessed from other applications

[Studio LFP]

If you implement a CotentProvider, you control what data you pass to the 
requesting application.

Just filter the data before you pass it back to the requesting application.

[android-developers] Re: Thanks, Android Developers are the BEST! Another question about databases?

[Studio LFP]

Android, along with most mobile OSes, don't excel at printing quite yet. I'm 
seeing movement toward more printing functions, but I doubt we'll see an all 
out print manager style functionality any time soon. I guess they might 
surprise us with it in the next version, but we'll have to wait and find out 
there.

That being said, do you have a support infrastructure planned with your 
application? Or are you planning on it being stand-alone on the 
phone/tablet?

I ask that because there are a lot of good ways to get files into certain 
formats if you have a server planned. Pushing the data to the server and 
asking it to format and print would produce significantly better results in 
speed and ease of use.

If not, a quick and easy way to get "pretty" formatted output would be a 
bitmap backed canvas. You could just toss text, lines and images all over 
and save it to a JPG or PNG.  It wouldn't produce the best printing results, 
but it would be a start.

Canvas: http://developer.android.com/reference/android/graphics/Canvas.html
Bitmap: http://developer.android.com/reference/android/graphics/Bitmap.html
Bitmap Factory: 
http://developer.android.com/reference/android/graphics/BitmapFactory.html

For nicer printed output, you could also look up the PDF spec and implement 
a slimmed down version of it in your code. Also, SVG may be an option as it 
is something that more and more browsers are supporting. You could then use 
a browser on a desktop to view and print them.

PDF: http://www.adobe.com/devnet/pdf/pdf_reference.html
SVG: http://www.w3.org/Graphics/SVG/

Hope that helps.

However it should be noted that this group is concerned explicitly
with the SDK, which is based on Java code.

If you want to learn how to program (for real) then you should learn
Java and the Android SDK.  If you are a computer science student, this
shouldn't be difficult, and is very typical of the workload expected
throughout an undergraduate course.

Using a basic variant for Android would have a number of drawbacks,
perhaps the biggest being: if you want to learn a skill that you can
use in a professional (or even hobbyist) manner, you're going to want
to use the actual framework, not a watered down version intended to
make it easier.

So go through the examples, and learn it for real, like I said, it
shouldn't be too difficult if you're a CS student already :-).

[KK]

Hi All,
I just copied this code from the web and trying to run it in Eclipse gives
me errors, the R.id.listView and R.layout.main are not getting resolved. No
idea whats going wrong here.
Please find the code for Java and mail.xml file as below:
---MyContentResolver .java
file is below:
package com.sailo.contentresolverdemo;

import java.util.ArrayList;

import android.R;
import android.app.Activity;
import android.content.ContentResolver;

import android.os.Bundle;
import android.provider.ContactsContract;
import android.provider.ContactsContract.PhoneLookup;
import android.util.Log;
import android.widget.ArrayAdapter;
import android.widget.ListView;

public class MyContentResolver extends Activity {
 private static final String TAG = "MyContentResolver";
private ArrayList list;

/** Called when the activity is first created. */
@Override
 public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
 setContentView(R.layout.main);

// Get content provider and cursor
 ContentResolver r = getContentResolver();
Cursor cursor = r.query(ContactsContract.Contacts.CONTENT_URI, null,
 null, null, null);

// Let activity manage the cursor
startManagingCursor(cursor);
 Log.d(TAG, "cursor.getCount()=" + cursor.getCount());

// Get value from content provider
 int nameIndex = cursor.getColumnIndexOrThrow(PhoneLookup.DISPLAY_NAME);
int numberIndex = cursor
 .getColumnIndexOrThrow(ContactsContract.CommonDataKinds.Phone.NUMBER);

cursor.moveToFirst();
 list = new ArrayList();
do {
String name = cursor.getString(nameIndex);
 String number = cursor.getString(numberIndex);
list.add(name + ": " + number);
 } while (cursor.moveToNext());

// Get the list view
ListView listView = (ListView) findViewById(R.id.listView);
 ArrayAdapter aa = new ArrayAdapter(this,
android.R.layout.simple_list_item_1, list);
 listView.setAdapter(aa);
}
}

Re: [android-developers] Re: Extracting RGB data from Bitmap

[New Developer]

Curious

ByteArrayOutputStream bos = new ByteArrayOutputStream(); 
bmp.compress(CompressFormat.JPEG, 100 , bos);

bos.toString();

and also

ByteArrayOutputStream bos = new ByteArrayOutputStream(); 
bmp.compress(CompressFormat.PNG, 100 , bos);

bos.toString();


the string result from bos.toString();   is this the raw or encoded 
version of the  image ?  I would guess encode because bos.size()  is 
much less than  bmp.getWidth() * bmp.getHeight().



So my question then is what is the encoding method used ?   and  to 
which  PDF filter do they correspond ?



Thanks in advance

[android-developers] Re: LVL, DeviceLimiter and userId

[Phil H]

In the developer console "active installs" is supposed to be the
number of devices that the software is currently installed on. I know
how many successful sales have gone through Google Checkout (this is
lower than the "total installs" on the developer console which I think
includes purchases cancelled inside the 15 minute returns window) and
the active installs figure is 40% higher than the total of successful
sales.

My conclusion, given that most of my sales are in the USA, is that
couples/families where at least a couple of people have an Android
phone may be sharing a generic Google Checkout account so that they
can buy an app once and share it around for free.

That's ok-ish when there is no ongoing cost of running a back end
server. It's going to destroy my business model if I need a back end
server though. I'm considering using the Google Order Number as a
licence key, thereby allowing multiple installations, but no
simultaneous use on different devices. And I'll write up a licence to
reflect that.

That is a convenience, not a requirement. The reason it works for
"other providers like contacts etc." is because those "other
providers" are part of the OS and classes with these symbols are made
part of the SDK.

[android-developers] Slidingdrawer hides last element of listview.

[charlie babitt]

Hallo!

In my activity I have a list view and I want to have a sliding drawer
at the bottom of the screen. The handle of the sliding drawer has a
solid image and the size of the whole screen width. The problem now
is, that the last row of the list is not visible anymore, since it is
below the sliding drawer's handle. What is the best solution to solve
it.
My layout looks as follows:

Activity layout:











My Handle Layout:


http://schemas.android.com/apk/res/android";>





Do you have any idea how I could fix this?
Thanks
Charlie

  http://www.reyburn.com/irct.html

This page from a competitor's website cites an accuracy of 0.01 cents
(which is musical terminology for 0.057).  This is the industry
standard for professional piano tuning devices.  So an uncorrected
10^(-5) would not be competitive.  That web page also mentions
automatic calibration through something he calls the "CyberCloud"
which I assumed was an NTP function through his server.  I can't
imagine how else he would do it.  Of course his product is on the
iPhone which does not have GC, so maybe that is the difference.

I am not sure what kind of instruments are you tuning, but since basic
crystal oscillator accuracy is in between 10^(-5) and 10^(-4) for
audible frequencies this seems as accurate as one would need.

Please keep in mind that A/C conversion delay and application jitter
caused by Garbage Collection will have effects of magnitude of tens of
milliseconds.

NTP over public networks will give you at most 10s of milliseconds
accuracy too and its main use is time synchronisation (making sure
that 2 timestamps by distributed machines are as close as possible),
rather than establishing how accurate your internal time source is.

I don't want to discredit your solution and as I said above, I don't
know much about the problem that you are trying to solve, but I simply
think that modern quartz oscillators will offer you as much accuracy
as you need for audio tuning.

[android-developers] authentication to the server

[arun kumar]

i want to connect to the sap server.
am posting my code


UsernamePasswordCredentials creds = *new* UsernamePasswordCredentials(
"username", "password");

AbstractHttpClient httpclient = *null*;

((AbstractHttpClient) httpclient).getCredentialsProvider().setCredentials(*
new* AuthScope(AuthScope.*ANY_HOST*, AuthScope.*ANY_PORT*),creds);



but it is not connecting ..can any one suggest me how to authenticate to the
serer

Hi,

Get UTC from GPS Location or NMEA.

[android-developers] Re: Embedding Activity from different Application, both applications using same library causing ClassCastException on inflating views

[smill]

Thanks Mark,
Using fragments would require to rewrite lot of code so for me it's
not a solution. I'll try to reproduce this problem with fragments
anyway.

I'm still waiting for an answer about the LayoutInflater job. It seems
my problem and the other refered in my previous post are related. If
we run 2 apps and use same library from both apps, only the first
app's layout resources inflated from library have view instantiated
correctly. The second activity gets the views from library
instantiated by the first app's classloader.

br,
smill
