It is possible however you will need to select the sim and then send a message, it also depends on the hardware implementation by the manufacture. Android has no default way of doing this.

I would change the code to

while (toRotation < 0.0f) {
toRotation += 360.0f;
}
while (toRotation >= 360.0f) {
toRotation -= 360.0f;
}

That should work and give you a bearing.

did you try my fix ?

if (toRotation < 0)
{ toRotation = toRoatation + 360 ;}

You mentioned 3-4 minutes, if you double the buffer size does it take half the time to get the delay ? Thinking it could be something like heap size and the GC jumping in. Other than that I don't see a problem with the code.

So the rotation is calculated from

final float toRotation = prevLocation.bearingTo(location);

The documentation says
https://developer.android.com/reference/android/location/Location.html#bearingTo(android.location.Location)

Returns the approximate initial bearing in degrees East of true North when traveling along the shortest path between this location and the given location. The shortest path is defined using the WGS84 ellipsoid. Locations that are (nearly) antipodal may produce meaningless results.

While (toRotation < 0)
{ toRotation = toRoatation + 360 ;}

My desktop also has powered USB even when shutdown, not sure how you would measure this without an external device. Just another dimension to think about.

pubnub appears to be just a relay system, driver gps data -> pubnub -> user. Still you need to check that the app is getting good valid data.

How are you getting the location (GPS/WIFI/BOTH) ?
Is that data 100% accurate or does it drop sometimes ?

Work out if locations are correct, and then you can start looking for a coding issue. if locations are dropped or bad data then you can correct the code and ignore them.

I mapped a push bike rides the other day and it reported I hit 56 mph for about 1 second. I know this is bad data because I would have remembered hitting that speed or pulled the breaks well before. It should be ignored.

this may sound like madness but try a smaller buffer say 40 bytes.

That is what I thought I had been doing, helping. If you are saying I've been of no help then I guess you are entitled to your opinion. If you are asking me to write the code for you then I would have to decline. If I wrote the code i would rob you of the chance to improve and learn.

The code you found gets you 90% of the way, come on I know you can do it. Read a little, try things, look at the code and understand it.

When you have a pet project and that's the best time to learn, you want something so go out and get it. We are here to help chat, not write the application for you. That would be cheating and take me away from my real job which pays the bills so I can help chat to you on here.

Well that depends on the specs, does the user have to select a video or could they just play one after the other ?

Do you want the application to remember which video has been played and continue from the last one seen ?

I could ask more questions and the answer may change what I recommend.

Is this a pet project or something commercial ?

/Darren

The code from stackoverflow is only one part and is missing the playing the routine. If you was able to put that together yourself then you can solve this with the pointers I gave

keep saying the same thing over and over doesn't make it happen, perhaps you should read up on intents and passing between them.

ok so this is the code

http://www.androiddevelopersolutions.com/2013/12/android-play-video-from-sd-card.html



/Darren

Its not hard coding, You already have the call vv.setvideopath() in the code you provided, You present a listview the user selects one of the items. You then load the intent extra and call the intent to play the video. However my passing just the filename of the selected item from the listview you sort of shoot yourself in the foot for playing any more. Why don't you pass the media store ?

Your code looks a lot like http://stackoverflow.com/questions/20007342/how-to-get-list-of-video-files-in-a-specific-folder-in-android have you been working on this for two years ?

/Darren

https://developer.android.com/reference/android/media/MediaCodec.html

No one is going to write the code for you, unless you are willing to pay with beer and bacon.

This will get you started it will play one video from the sd card. So you will have to work out how to scan a directory and loop around.

String SrcPath = "/sdcard/Video/how_to_use_google.mp4";

setContentView(R.layout.main);
VideoView myVideoView = (VideoView)findViewById(R.id.myvideoview); //This is a videoview in the xml
myVideoView.setVideoPath(SrcPath);
myVideoView.setMediaController(new MediaController(this));
myVideoView.requestFocus();
myVideoView.start();

With this basic example you should be able to research the rest.

Make setListAdapter(listAdapter); the last call

Are you talking about an application you have written ? Since Android 4.1 (Jelly Bean version), Android seems to provide access to hardware accelerated decoders at application level through JAVA APIs.

If you are talking about application from the play store or already pre built then I would say probably.

In the link provided you will see

for printing an image the coder does

byte[] sendData = null;
PrintPic pg = new PrintPic();
pg.initCanvas(384);
pg.initPaint();
pg.drawImage(0, 0, "/mnt/sdcard/myimage.jpg");
sendData = pg.printDraw(); !<--- render data first
mService.write(sendData);

You will need to render the PDF before printing

configuring the wireless camera is the key, with that setup displaying the data should be easy. with 100's of wireless cameras available it would be foolish for me to give advise on its setup. Google or youtube maybe your friend.

HttpResponse httpResponse = httpclient.execute(httpPost);

Should be called asynchronously, but I'm not sure if that is the problem.

Hacks or users ? for hack web site you visit then https://play.google.com/store/apps/details?id=org.mulliner.telstop

users on the other hand will always find a way unless you replace the dialler I feel.

google says...

http://www.codeforge.com/article/220087

Maybe you might get more help on https://groups.google.com/forum/?fromgroups#!forum/android-ide Id never heard of ide until I read this.

A guess but on the tablet did you change the SERVER address ?

try displaying the file with the font "Arial Unicode MS" this should work for both English text and Tamil.

I've not reviewed the code but the comment

/**
* This is where we can add markers or lines, add listeners or move the camera. In this case, we
* just add a marker near Africa.
* <p/>
* This should only be called once and when we are sure that {@link #mMap} is not null.
*/


Notice the near Africa ?

There are plenty of ways to debug your phonegap code on android:

o logcat
o Weinre: http://people.apache.org/~pmuellr/weinre/docs/latest/Home.html
o Chrome Remote Debugging (only Android 4.4+): https://developer.chrome.com/devtools/docs/remote-debugging

I have no knowledge of the tools or application but if I had to guess it could be folder names causing a failure when it fails to find the .exe

example:
C:\PROGRAM FILES\FILENAME.EXE
If you have another folder called
C:\PROGRAM it will look in that location and fail, you need to put the original execution line in double quotes "C:\PROGRAM FILES\FILENAME.EXE"

or rename the folders if you have no control over the execution location.

so it works but you don't know what to do with the returned barcode scan ?

I would have to ask why ? is it important to low memory usage ? if so then java may not be the best language.

You can call repeatedly

System.gc();

this should reduce the heap and return memory and the number of times it needs to be called depends on the GC algorithm.

Is zxing (barcode scanner) installed ?
Does it work standalone ?

what are you expecting to happen when the image is made larger ? why do you feel this is a problem ?

Whilst it looks old, this may help you

https://groups.google.com/forum/#!topic/android-ndk/pUfqxURgNbQ

not sure on the version of gcc you are using but the thread mentions a patch is needed.

is this the problem

https://tracker.crystax.net/issues/833

Using your part number one web site reports "RJ45 and WiFi optional" and the manufacturers site didn't even mention it. Every site reported demo code and SDK but no link, do you have the code/SDK ?

I'm the same as Richard with regards to encryption but reading the java code it looks like its using padding whilst the c# has PaddingMode.None;

What are you saying, this code sample doesn't work ? the SMS is delivered even when abc123 is in the message ? what is the real problem ?

You need to put more effort into the question before any meaningful answer is going to come out.

You say secure do you mean all three systems are in the same room with a locked door and only you hold the key ?

Secure as in they need to login ?

Secure as in the data needs encrypting ?

Chat program is this text or voip ?

Do you really only need 2 clients or is that the minimum ?

Have you even search here on code project

http://www.codeproject.com/Articles/524120/A-Java-Chat-Application

Might not cover all your needs but its a start and may help you understand what might be needed.

Can't see anything else wrong, what happens if you debug the routine ?

have you tried to call repaint()

should have re read the above ignore ^^^^ (the idiot above asking questions)

is this when you change the combo box ?

could you post the exception

SMB = Server Message Block and it maybe Mozilla implements it, you could use JCIFS if all else fails https://jcifs.samba.org/

You could try

new File("\\\\server\\path\\to\\file.txt")
// (double-backslashes required for backslashes in path)

Not 100% but this could be windows only

and the problem is ?

Have you looked at

It may answer your question

What make of phone ?

Some manufacturers have specific USB drivers. Try googling

samsung usb driver
htc usb driver

or whatever the phone is...

This may help you get started

http://www.codelearn.org/android-tutorial/twitter/introduction

I know and I don't know what happened, when I looked the post was unanswered I went to mock up the code and noticed the return; so I posted. When I came back to look at the item your post was hours before mine so it made my post look dumb... perhaps I should refresh the tab just to make sure no one has answered in between.

This is an OS level operation and should have been performed before the user runs your application. So are you talking about listing all the available wifi hotspots and attempting to connect to one or just opening a socket that happens to be wifi ?

I've never seen it used like that, and looking at the docs http://docs.oracle.com/javase/tutorial/essential/io/pathOps.html I don't believe its possible

http://www.achartengine.org/content/javadoc/org/achartengine/renderer/XYMultipleSeriesRenderer.html#setYLabelsColor(int, int)

Are you sure ?

doesn't this depend on how the images are stored ? if they are stored as individual items that all need one request each then threading might be the answer. Of course store them in chunks of 10-15 and each request loads 10-15 items.

When you say run, you mean in the emulator or on a live phone ?
What is 192.168.1.16 the same system you run the emulator on ?

Are we talking Adobe flash player, if so then look at how to restrict playing or security at the Adobe site. it's also worth mentioning Android no longer supports Adobe Flash Player, since June 2012. Adobe hasn't made a new version since then, and on Android 4.4 the player will not function.

Are you asking to play the flash only on that phone is that the restriction ? or does the device have restrictions ?

Have you contacted the Author ?

Don't see any question

Perhaps provide people with an example of your code, if the file ends up in the adobe folder you are just using an intent to call whatever pdf reader is installed ? More information about how you are doing the action will help get you an answer....

What you describe can be normal, the filter is simple. If you have a list of names and none of them begin with "z" type that in and they will all disappear. This type of filter will only match the beginning of words.

example :

one
two
three

type r nothing will show
type t (two and three should be left)
type th (three should be left)

if you want something better than this simple filter you need to create your own adapter and write the code.

Or you may just have a bug in the implementation :-)

I will tidy up what I have and send you a link.

/Darren

Please check what you have posted and correct links if needed, adding code help people to understand what you are doing. As it stands this is unanswerable.

ok I tried, good luck

I noticed you added a few bugs to this, perhaps the problem lies in TextualMetaEvent.java or text.java

I'm unable to see the images the site times out, did you try PinyinTest I pointed out on the link above ?

So are you saying they don't appear, or because of a hardware limitation you can't press a button to get them to appear ?

Mexcromex showed up nothing in Google, does the phone go by any other name ?

Are you talking about the colours (theme used) then the answer is no, Someone on 2.3.3 could have an ICS theme and your picker would look like it does on 4.0.3.

Having a custom control picker should get you around any other issues

seems to have been cut off during the transfer

no you don't need a rooted phone, you have a wireless router that your pc is connected to ? then all you need to do is attach you phone to the wireless and reference the 192 address of the web server on your pc. failing that use the 3g network and use dynamic dns or something to present you pc on the internet.

so the API number for 1.5 is 3 and 15 is 4.0.3, set the manifest to 3 and see if the app still works. If you have called any API from a higher version the app will fail to compile.

http://www.codeproject.com/Articles/191930/Android-Usb-Port-Forwarding might be worth a read

so you need to get a network between the phone and website, wireless or 3g and change the address to that of the webserver

This works on the emulator and not on a phone and that is down to the address 10.0.2.2 (special loop back 127.0.0.1).

If you want this to work on a phone, you need to change the ip address. So if you are using wireless within your hub use the registered address from the hub. If your outside using 3g or another wireless network you will need to find the external address of your hub and allow a port forward)

what are you attempting to do, what code do you already have ?

Just plug the phone in via usb and from eclipse hit the debug, that will deploy and run the application on the phone.

When you say read a pdf, are you using a library or intent to fire up the application ?

did you click on the UI elements XML link ? I'm sure that answers the problem.

You need to override onSaveInstanceState not call it and the same goes for onRestoreInstanceState.

good call and worth 5
