I'm trying to make a call with AT COMMAND, but i cannot open port of neither of COM1,COM2,COM4,COM9,COM10.
Source Code:
System.IO.Ports.SerialPort m_serialPort;
m_serialPort = new System.IO.Ports.SerialPort();
m_serialPort.PortName = "COM1";
m_serialPort.BaudRate = 115200;
m_serialPort.DataBits = 8;
m_serialPort.StopBits = System.IO.Ports.StopBits.One;
m_serialPort.Parity = System.IO.Ports.Parity.None;
m_serialPort.Handshake = System.IO.Ports.Handshake.None;
m_serialPort.DtrEnable = true;
try
{
m_serialPort.Open();
MessageBox.Show("COM port is ready.");
}
catch
{
MessageBox.Show("Error opening the COM port.");

Is it possible to customize the XDA's today screen (i.e. by using XML) as you can do with the Orange's SPV ?
Download Microsoft's Theme Generator...
http://www.microsoft.com/mobile/pocketpc/downloads/powertoys.asp
There are some other goodies on that page aswell.
Good luck!
Powertoy is not what I am looking for: the idea is not only changing the background image but to organize all the datas on the screen as and where you wish (date, time, numbers of emails received, fonts, etc.) as you can do on smarphone 2002 changing the today screen's script in XML.
For examples what you can do with Smartphone 2002:
http://www.smartphony.org/stories.php?topic=32
It's a bit more complicated with PPC 2002. Unlike smartphone, it is an API to change the contents of 'Today'. Each line is loaded as a type of 'snap in' dll.
Do you I could find some examples of that kind of work ?
It is really a pain in the ass
But this works fine... 8)

Is there somewhere a technical documentation about that ?
I looked all over the net and I couldn't find something that works.
First there is this:
Code:
File wave1 = new File(wavFile1);
if(!wave1.exists())
throw new Exception(wave1.getPath() + " - File Not Found");
AudioInputStream clip1 = AudioSystem.getAudioInputStream(wave1);
AudioInputStream clip2 = AudioSystem.getAudioInputStream(new File(wavFile2));
AudioInputStream emptyClip =
AudioSystem.getAudioInputStream(new File(emptyWavPath));
AudioInputStream appendedFiles =
new AudioInputStream(
new SequenceInputStream(clip1, emptyClip),
clip1.getFormat(),
clip1.getFrameLength() + 100
);
clip1 = appendedFiles;
appendedFiles =
new AudioInputStream(
new SequenceInputStream(clip1, clip2),
clip1.getFormat(),
clip1.getFrameLength() + clip2.getFrameLength()
);
but android dosen't support java.sound.sampled
there is also this:

but is also dosen't work.
In all cases the result sound file is empty without sound.
How can I merge two *.wav files?
I m also searching for months like MP3 EDITOR LIKE software..which can combine two or more sound file and make one..
But all apps i found is just mp3 cutter..
There is one app in symbian os my friend have in his c6
Which do editing i forgot the name but for sure in android i have not found one since six months
we all should be polite enough to press thanks for anyone who helped US.

From the error, I can tell that .val isn't declared, or something similar, but I need help from an expert to fix it.
Faced with same problem for Alcatel OT Fire E 6015X. My solution:
- Install Android NDK (ArchLinux):
Code:
pacman -S android-ndk
- Add path:
Code:
export PATH=/opt/android-ndk/toolchains/arm-linux-androideabi-4.6/prebuilt/linux-x86_64/bin:${PATH}
- Run build:
Code:
make CROSS_COMPILE=arm-linux-androideabi- ARCH=arm zImage
need to replace every .val for .cur.val, the problem is that the val variable is declared within a union named cur inside the v4l2_ctrl structure. So in order for the Compiler to recognize it should be addressed thru the union var
I'm starting to build an app that needs 2D drawing on Android Studio and even after some search I still have some troubles understanding some things. My intention is to draw Balls as objects, so that I can specify its radius and locations to draw. That ball should be a filled circle.
So here are my questions:
1. How to create the ball class in the most organized way? (Its constructors, methods, and stuff like that)1. Where to call that class to create balls?(what should I do on the onCreate() method? My coding should go in my MainActivity class?)1. How to draw them by a timer?(create a ball with a random radius and position and draw it on screen)1. Where to draw them? (container)
I saw a lot of things using canvas, the mysterious onDraw() method and I didn't get much of it.
I didn't understand how to control when to draw it.
I used this code for leaning and kinda control the drawing of objects , but It seems too messy and dont feel right.
Its a sensor controlled ball.

Hi all,
I know how to set proxy in a webview under Android 4.4 and less, using java reflection.
But anyone knows how to set a webview proxy under Android 6.0 ? Unfortunatly my methods don't work on this Android version ...
Thanks a lot in advance !
[EDIT] Solved, see post #2
Solved by projection :
Code:
private static boolean setProxyKKPlus(WebView webView, String host, int port, String exclusion, String applicationClassName) {
LOG.warn("try to setProxyKKPlus");
Context appContext = webView.getContext().getApplicationContext();
System.setProperty("http.proxyHost", host);
System.setProperty("http.proxyPort", port + "");
System.setProperty("http.nonProxyHosts", exclusion);
System.setProperty("https.proxyHost", host);
System.setProperty("https.proxyPort", port + "");
System.setProperty("https.nonProxyHosts", exclusion);
try {
Class applictionCls = Class.forName(applicationClassName);
Field loadedApkField = applictionCls.getField("mLoadedApk");
loadedApkField.setAccessible(true);
Object loadedApk = loadedApkField.get(appContext);
Class loadedApkCls = Class.forName("android.app.LoadedApk");
Field receiversField = loadedApkCls.getDeclaredField("mReceivers");
receiversField.setAccessible(true);
ArrayMap receivers = (ArrayMap) receiversField.get(loadedApk);
for (Object receiverMap : receivers.values()) {
for (Object rec : ((ArrayMap) receiverMap).keySet()) {
Class clazz = rec.getClass();
if (clazz.getName().contains("ProxyChangeListener")) {
Method onReceiveMethod = clazz.getDeclaredMethod("onReceive", Context.class, Intent.class);
Intent intent = new Intent(Proxy.PROXY_CHANGE_ACTION);
Bundle extras = new Bundle();
List<String> exclusionsList = new ArrayList<>(1);
exclusionsList.add(exclusion);
ProxyInfo proxyInfo = ProxyInfo.buildDirectProxy(host, port, exclusionsList);
extras.putParcelable("android.intent.extra.PROXY_INFO", proxyInfo);
intent.putExtras(extras);
onReceiveMethod.invoke(rec, appContext, intent);
}
}
}
} catch (Exception e) {
LOG.warn("setProxyKKPlus - exception : {}", e);
return false;
}
return true;
}
parameters
what is exclusion and applicationClassName parameters? Im trying to setup proxy on Api 21+
Is anyone able to use buildPacProxy method instead of buildDirectProxy method of ProxyInfo to set the proxy of webview?
