[android-developers] Re: Please help me to get a rid of this error - The type android.app.Fragment cannot be resolved

[Jonathan S]

android.support.v13 is for API Level 13+ only

If you are doing Minimum API Level 8, you have to remove 
android.support.v13

[Manas Shah]

Thanks Nobu for reply

Yes, I have set minSdkLevel = 8 and targetSdkVersion =15 but still no
luck...

I am not able to understand why code is referring to android.app.Fragment
class as I am no where using it.

Thanks again,
Manas

[Nobu Games]

If you compile the app with API level 8 (Android 2.2) then the class 
Fragment cannot be found because it does not exist there. It has been 
introduced with API level 11. Make sure to set the target API level to the 
highest your app can support and minSdkLevel to 8.

Sounds like you will want to launch the Adobe PDF Reader.  I'm guessing you

intent.setPackage("com.adobe.reader");
intent.setDataAndType(Uri.parse(doc), "application/pdf");

Rename your 5MB database file to something Android does not recognize by the 
extension ( I used .db.jet ) and then use that raw resource as the source when 
copying. Works for me.

Then copy the corrupted file to your desktop and do a binary compare with 
the original. This may give you some clues about what is going wrong.

nope, I can check which file read in which order by logs. They are in

I would very strongly advise you against doing this.  There is 
no guarantee that the binary database file will be compatible across 
Android version and much less across all custom ROMs.

If you believe that the user truly wants a service to run forever --
say, a music player -- use startForeground(). The user will see a
Notification and know that your service is running. The Notification
should provide a means for the user to shut down your service.

Better yet, reorganize your project to avoid the everlasting service
in the first place, such as using AlarmManager to get control
periodically.

Thanks for the reply. I realized this that I had Login activity 2

Thanks a lot for the reply, how come the catlog do not show property
error message here. Anyway the problem is resolved and thanks to all.

Re: [android-developers] Re: Please help me with calculating direction from point A to B

[Frank Weiss]

Sounds like writing some unit test cases would help. Of course, you may need
to refactor the code to make it testable.

The advantage would be that you will see more clearly the input parameters
and the constraints. It would divide and conquer the problem. The test
cases would be the theory of what the sensors say and what the algorithm
should output. If either of these theories needs adjustment, it is then
easier to fix the algorithm.

[android-developers] Re: Please help me with calculating direction from point A to B

[Per]

hmm..

Have you checked the numerical values that you get (mHeading,
mBearing, angleDegrees) ?
Log them and check if they look reasonable (assuming that you know
where north is :). Expect some deviation caused by your surroundings.
Not only the Earth is magnetic...

If that looks ok, I'd suggest to recehck your line drawing code.
I took a simpler way (having some arrow bitmap to draw):

Drawable d = get_your_bitmap();
canvas.save();
canvas.rotate(angleDegrees, centerX, centerY);
d.draw(canvas);
canvas.restore();

Re: [android-developers] Re: Please help me with calculating direction from point A to B

[Pedro Teixeira]

Per can you explain your example a little bit further?
My code seems fine but the direction of the arrow doesnt seem accurate:


public void onSensorChanged(SensorEvent event) {
	double mLatitude  =  (mLocation.getLatitude()); // lat1 location  
manager
	double mLongitude =  (mLocation.getLongitude()); // long1 locationg  
manager
	double picLatitude = Double.parseDouble(picLatitudeString); //lat2  
fixed
	double picLongitude = Double.parseDouble(picLongitudeString); //long2  
fixed

float mHeading = event.values[0]; // azimuth value
float[] results = new float[1];
Location.distanceBetween(mLatitude, mLongitude, picLatitude,  
picLongitude, results);

float mBearing = results[1]; // bearing
float angleDegrees =  ((mBearing - mHeading)+360) % 360;

myCompass.updateDirection(angleDegrees);
}

The update method goes simply like this:

public void updateDirection(float dir)
{
firstDraw = false;
direction = dir;
invalidate();
}

And this is how I draw the compass:

public static class compassLook extends View {

private Paint paintPointer = new Paint(Paint.ANTI_ALIAS_FLAG);
private Paint paintCircle = new Paint(Paint.ANTI_ALIAS_FLAG);
private Paint paintLeters = new Paint(Paint.ANTI_ALIAS_FLAG);
private boolean firstDraw;
private float direction;

protected void onDraw(Canvas canvas) {
int cxCompass = (getMeasuredWidth()/2);
int cyCompass = (getMeasuredHeight()/2);
float radiusCompass;
if(cxCompass > cyCompass){
 radiusCompass = (float) (cyCompass * 0.9);
}
else{
 radiusCompass = (float) (cxCompass * 0.9);
}
// circle drawing
canvas.drawCircle(cxCompass, cyCompass, radiusCompass, 
paintCircle);
if(!firstDraw){ 

// line pointer
 canvas.drawLine(cxCompass, cyCompass,
		   (float)(cxCompass + radiusCompass * Math.sin((double)(-direction)  
* 3.14/180)),
		   (float)(cyCompass - radiusCompass * Math.cos((double)(-direction)  
* 3.14/180)),

   paintPointer);
double mLatitude  =  (mLocation.getLatitude()); //lat1
double mLongitude =  (mLocation.getLongitude());//long1
double picLatitude = 
Double.parseDouble(picLatitudeString); //lat2
double picLongitude = 
Double.parseDouble(picLongitudeString); //long2


 // Distance formula (harversin)
float R = 6371; // km
float dLat = (float) 
Math.toRadians(picLatitude-mLatitude);
float dLon = (float) 
Math.toRadians((picLongitude-mLongitude));
float a = (float) (Math.sin(dLat/2) * Math.sin(dLat/2) +
			Math.cos(Math.toRadians(mLatitude)) * Math.cos 
(Math.toRadians(picLatitude)) *

Math.sin(dLon/2) * Math.sin(dLon/2));
float c = (float) (2 * Math.atan2(Math.sqrt(a), 
Math.sqrt(1-a)));
float distancia = R * c;

		 canvas.drawText(String.valueOf(distancia*1000) + "m", cxCompass-30,  
cyCompass+20, paintLeters);

}

}

I didn't wrote all the methods on compssLook since they are not  
relevant..

Now about the compass

There are two ways you can think about this:

First, take the value you get from the algorithm and make it into a
vector in 3D space (i.e. think of the arrow you're going to draw to
indicate direction). Then:

One: Compute the device's orientation matrix using sensor data.  
Take the
inverse of this matix, and multiply the "arrow" vector by this  
matrix.


Two: Compute the device's orientation matrix using sensor data.  
Rather

than interpreting it as a rotation matrix, think of it as defining a
plane in space (aligned with the device's screen).  Then project the
"arrow" vector onto this plane, in the plane's coordinates.

You might want to start with compensating just for the vertical axis
(the device's rotation from the true north direction), it might be  
enough.

Pedro,



If I understand you correctly, you are having difficulties with the
device's orientation.



The bearing angle seems to be computed in the horizontal plane. If
you wish to adjust for the device's orientation, you need to
concatenate it with the bearing angle.



Google for "quaternions".



This is a (relatively) simple math technique to work with rotations
the same way you can work with vectors: add / subtract,  
interpolate.

Hi everyone...


I'm back with the same issue for the last couple of days… I'm  
trying

to create a compass for my application BUT the difference is that,
instead of having a line always pointing to north, I want this  
line to
point for a specific point. I've been trying dozens of  
algorithms and

nothing works..
I've finally found one that points me exactlly to the point I  
want..
BUT it doesn't move if I change the position of the device which  
is my
objective.. basicly, what I want is that no matter the direction  
I'm

using my device.. the line always point me to the point
(picLatitude,picLongitude)…


I understood that for the line to move, I can't use static  
variables…
I need to use the values offered by the onSensorChanged 
(SensorEvent

event).



This are the data I have available:



event.values[0]: azimuth, rotation around the Z axis (device in
relation to north, 0º)
event.values[1]: pitch, rotation around the X axis
event.values[2]: roll, rotation around the Y axis
mLatitude: device current latitude gottern from GPS (variable)
mLongitude: device current longitude gotten from GPS (variable)
picLatitude: static picture latitude established previously
picLongitude: static picture longitude established previously
distance: distance in Km from device to the picture calculated
previously



And this the formula that works correct, and gives me the correct
angle.. ( BUT IT DOESN'T USE ANY OF THE SENSOR DATA SO THE LINE
COMPASS DOESNT MOVE):



double dLong = picLongitude - mLongitude;
double y =  (Math.sin(dLong) * Math.cos(picLatitude));
double x =  (Math.cos(mLatitude) *

Use SystemClock and the uptimeMillis() method. Quoting the SystemClock
documentation:

"This clock is guaranteed to be monotonic, and is the recommended
basis for the general purpose interval timing of user interface
events, performance measurements, and anything else that does not need
to measure elapsed time during device sleep."

[android-developers] Re: Please help me with permission problems

[Brion Emde]

Ok, I was wrong.

Apparently, changing the security on the ContentProvider resulted in a
new database being created. I was thrown off by the empty screen of my
ListView that I was getting a security failure. But there was no
message.

So, I can create, update, delete and read the data in the new
database.

Thanks!

[android-developers] Re: Please help me with permission problems

[Brion Emde]

I discarded the permissions on the Activities, as I didn't know why
they were there either, I was trying out that example.

If I go with a permission entry on my ContentProvider, I cannot query
the data. If I change the android:permission on my ContentProvider
like so:



I cannot query the data. I do have, as shown above, the uses-
permission element declared at the top of my manifest file.

Thanks Mark, that's helpful.

What I was trying to do was to get that example to work that I posted
a link to.

Then I was going to try to figure out what I actually need. So far,
I'm pretty stupid as far as Android permissions go.

[android-developers] Re: Please help me find documentation on actions for the manifest file

[Alberto]

I'm adding to this thread because I too was looking at using the Gmail
content provider. I understand it's not documented as part of the API
(and I think it should be) but that hasn't stopped popular apps like
SMS Popup from using and building apps on the undocumented SMS API for
example.

Of course, I haven't been able to get the GMail content provider to
work, every time I try to get a cursor I get back null with code like
this:

Cursor mailCursor = context.getContentResolver().query(Uri.parse
("content://gmail-ls/messages/myownem...@gmail.com/"), (new String[]
{"_id", "fromAddress", "subject"}), null, null, null);

Has anyone been able to get a cursor from the Gmail provider? Any help
would be appreciated as there are a few of us looking to try this.

[Samuh]

I think, one of the problems could be with the use of localhost in
your server URL:
"http://localhost:8080/J2ME/servlet/HelloServlet";

Try specifying the IP address of your machine instead and see if it
helps.

thanks

i will show you the code , i have try to connect httpserver with
j2me .it works.the httpserver is running in my tomcat.

part 1 :...i have created two TextView  to input userid and
password;so i try to get the InpustStream
code:
switch(v.getId()) {
case R.id.ok:
 //the code of  class PackMessage show you later
PackMessage pm = new PackMessage();
   //sendContent to get the message that have packed
sendContent = pm.login(id.getText().toString
(), pas.getText
().toString());
  //let sm get packedm.toString
SendMessage sm = new SendMessage
(sendContent.toString());
  //the class SendMessage have implemented Runnable
Thread smthread = new Thread(sm);
 //so turn to method run in class SendMessage
smthread.start();
break;


case R.id.cancel:
finish();
break;
   }


part2: this is the code of class PackMessage


public class PackMessage {
public StringBuffer  login(String userid,String password)
{


   //put the input from in sb


StringBuffer sb = new StringBuffer();
sb.append("login");
sb.append(""+userid+"" );
sb.append(""+password+"");
return sb;


}



}


part3:the constructor of  class SendMessage

   public SendMessage(String sendContent)
{
SendMessage.sendContent = sendContent;
}


part4:   the code of   run();


public void run() {


getHttpStream();
Intent Intent = new Intent();
// that is the point :getHttpStram();
Intent.putExtra("id", getHttpStream().toString());
Intent.setAction("com.google.lm.Main");
startActivity(Intent);


}


part5 : code of getHttpStram();and the


public static InputStream getHttpStream() {
HttpPost httppost = new HttpPost("http://localhost:
8080/J2ME/servlet/
HelloServlet");
DefaultHttpClient httpclient = new DefaultHttpClient
();
StringEntity reqEntity;
try {

Hi Ash,

I work for a company called PerfectoMobile (used to be Nexperience).
See www.perfectomobile.com.
We enable access to real mobile devices via the web.
You can install your app on the device and test it as if you were
holding the device
in your hands.

We just launched a campaign especially for our Android developers and
I thought that might be interesting for you. We offer you access to
over a dozen of the hottest Android devices for a special deal.

Just check out this campaign by following the link below:

http://www.perfectomobile.com/portal/cms/android.html

Have fun!

Unless you have 1000 students at a time to cater for, I see no need to
buy 20 phones.  Just buy one of each of the 5 most popular phones at
the time, and save the budget for future releases.

Developing on the emulator is perfectly fine and is easier than
transferring to the device each time.  You only need to test on a
device when you're ready to release, at which point you want to test
on as many different devices as possible.

[android-developers] Re: Please help me to choose Android Phones (For Android development)

[PJ]

Pankaj, I'm in the same boat as you are: I'm an independent developer
that doesn't have funding to buy 20 phones.

The emulator comes with a lot of options, so that could be used to
some extent to simulate different devices.  You can simulate slower
devices with -cpu-delay, set the resolution with -dpi-device and -
scale, etc.:
http://developer.android.com/intl/fr/guide/developing/tools/emulator.html#startup-options

But, it's impossible to test for everything.  When I published my
first app, I found out the hard way that for Hero phone users, the
soft keyboard wouldn't pop out for them.  I got some bad reviews and I
had to publish a quick fix.

Neverthelss (I'm pre-empting the Android haters), I'd much rather an
app work on 80% of 20 different Android devices than 100% of a handful
of Apple devices.  No open platform is perfect, but Android rocks in
my book.

[Pankaj Godbole]

I agree that quality is priceless. I know this first-hand from
spending several years in testing and quality assurance.

It might be possible for an institution to purchase 20 different phone
models to test on. But how is an independent individual developer like
me supposed to purchase so many phones, when perhaps all of them would
be locked to a carrier and most would come with a 2yr service
agreement? I am also not based in the US.

Is there a more feasible way without compromising on quality?

Eric's spreadsheet is awesome! Here's another one I found pertaining
to US carriers:

I can't agree more with Eric.  Why get 20 phones that are all
identical?  Get some variety so that you write apps that work as
expected for multiple devices.  You can't put a price tag on quality.
It's not worth saving $50 per phone if you end up writing an app that
breaks on a particular device and you get a bunch of upset customers
and bad ratings/image.

You definitely want to vary things like:
* hard keyboard vs soft keyboard
* high-res screens vs low-res screens
* fast vs slow cpus

And Eric's link to that spreadsheet is freaking great.

[android-developers] Re: Please help me to choose Android Phones (For Android development)

[Eric Wong (hdmp4.com)]

I would say get at least one unit for each Android models out there?
Since every unit seems to have slight variation of Android
implementation and apk tested on one may not work on the other.

Hope this spreadsheet would help

Re: [android-developers] Re: Please help me to choose Android Phones (For Android development)

The ADP1 is a great phone, but essentially the same thing as a T-Mobile G1.
We've done most of our development on these phones, and they're powerful,
robust and reliable.

But, as I said, it's unlikely they'll get Android 2.0, and they are HVGA.

@Nightwolf: my understanding is that the Galaxy either has no hardware 3D
support, or that it's not properly enabled. I recently read an article about
how some people found a hack (stole a file from the G1 and put it on the
Galaxy) that enabled 3D HW, but this only worked on rooted phones.

Note: I have never laid my hands on one, let alone tested it. I am repeating
what I've read in various Android communities on this topic.

Warm regards,

If you are a university I would contact Motorola and HTC directly.

In general these sorts of large corporations have University liaison
programs in place.

In fact you might get it cheaper "for academic purposes" then you
could on the street or
through normal channels.

Thank you so much Scott, Patrick, Pankaj and others...
This thread is of great help to me and to others like me. Please  keep
this
thread going adding your viewpoints and comments.

 And also could you please help me find where can we order the
Motorola Droid
and some HTC phones. As we are ordering for the university, we do not
use the phone service
of any carrier. We just require the instrument without any service
plan or contract.

Thank you

[android-developers] Re: Please help me to choose Android Phones (For Android development)

[Pankaj Godbole]

This is a good analysis of which phones to consider for development.

I also am ready to purchase a phone for testing of real-world apps
(i.e. not for educational purposes). I have been advised by a couple
of people to consider purchasing the ADP1 from Google.

What are your views on using the ADP1 which is, moreover, an unlocked
phone.

Thanks

[android-developers] Re: Please help me to choose Android Phones (For Android development)

[Patrick]

There is one more thing to take in to account, are they just learning
to develop or will they actually produce software that others can use?
As it is now most Users have a HTC Magic or Hero which means for that
something the runs on a new phone might not do as well for the general
public also while a keyboard is nice it's in my opinion often better
while learning to develop not to start with something that might later
on require you to learn it all over again, many people will not have a
physical keyboard and forgetting that during development can lead to
trouble.
This ofc if it's more then just learning the basic idea of the system,
I would personally go for the HTC Magic since if you get stuff working
on that you can more or less count on it working well on all phones.

Please trya  clear title that rel;ates to ty7our problem. and in the
text describe what you ahve tried or read until this point, and why
that may not be working.
