  • Why would JmDNS service discovery work on a Motorola Droid running Android 2.1-update1 and not on an

    - by Churlbong
    I have successfully gotten JmDNS working on Android 2.1 testing on a Motorola Droid by using MulticastLock, but recently got an HTC Incredible as second test device, and JmDNS discovery doesn't work at all. I should mention that broadcasting a service still works and everything appears to run normally, but serviceAdded() never gets called. Does anyone have thoughts on why this might be? I was thinking it might be a permission issue, but I don't get any exceptions...

  • Creating a drawable rectangle in xml with one gradient on the top half and another on the bottom hal

    - by synic
    I'm trying to create a drawable in xml, a rectangle with one gradient on the top half, and another on the bottom half. This is NOT the way to do it, apparently: <?xml version="1.0" encoding="utf-8"?> <layer-list xmlns:android="http://schemas.android.com/apk/res/android"> <item> <shape android:shape="rectangle"> <gradient android:startColor="#5a5a5a88" android:endColor="#14141488" android:angle="270" android:centerX="0.25"/> </shape> </item> <item> <shape android:shape="rectangle" android:top="80px"> <gradient android:startColor="#5aff5a88" android:endColor="#14ff1488" android:angle="270" android:centerX="0.25"/> </shape> </item> </layer-list> How can I do this, preferably in a way that makes it stretchable to any height?

  • SurfaceView for Camera Preview won't get destroyed when pressing Power-Botton

    - by for3st
    I want to implement a camera preview. For that I have a custom View CameraView extends ViewGroup that in the constructor programatically creates an surfaceView. I have the following components (higly simplified for beverity): ScannerFragment.java public View onCreateView(..) { //inflate view and get cameraView } public void onResume() { //open camera -> set rotation -> startPreview (in a thread) -> //set preview callback -> start decoding worker } public void onPause() { // stop decoding worker -> stop Preview -> release camera } CameraView.java extends ViewGroup public void setUpCalledInConstructor(Context context) { //create a surfaceview and add it to this viewgroup -> //get SurfaceHolder and set callback } /* SurfaceHolder.Callback */ public void surfaceCreated(SurfaceHolder holder) { camera.setPreviewDisplay(holder); } public void surfaceDestroyed(SurfaceHolder holder) { //NOTHING is done here } public void surfaceChanged(SurfaceHolder holder, int format, int w, int h) { camera.getParameters().setPreviewSize(previewSize.width, previewSize.height); } fragment_scanner.xml <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent"> <com.myapp.camera.CameraView android:id="@+id/cameraPreview" android:layout_width="match_parent" android:layout_height="match_parent"/> </RelativeLayout> I think I have set the lifecycle correct (getting resources onResume(), releasing it onPause() roughly said) and the following works just fine: pressing home and returning pressing Taskswitcher and returning rotation But one thing doesn't work and that is when I press the power-button on the device and then return to the camera-preview. The result is: the preview is stuck with the image that was last captured before button was pressed. If I rotate it works fine again, since it will get through the lifecycle. After some research I found out that this is probably due to the fact that surfaceView won't get destroyed when the power-button is pressed, i.e. SurfaceHolder.Callback.surfaceDestroyed(SurfaceHolder holder) won't be called. And in fact when I compare the (very verbose) log output of the home-button-case and the power-button-case it's the same except that 'surfaceDestroyed' won't get called. So far I found no solution whatsoever to work around it. I purposely avoid any resource cleaning code in my surfaceDestroyed(), but this does not help. My idea was to manually destroy the surfaceView like asked in this question but this seems not possible. I also tested other applications with surfaceViews/cameras and they don't seem to have this issue. So I would appreciate any hints or tips on that.

  • non-latin email address validation

    - by Eric Di Bari
    Now that ICann is allowing non-latin-character domain names, should I be concerned about e-mail validation? Currently, my sites are using php functions to ensure some alpha-numeric character set in each segment of an email address. Will these other character sets, such as Cyrillic, Arabic, and Chinese, pass validation? Are there recommended php functions to utilize for this?

However, i'm getting to the point where i'm reaching the limit of 500 sent emails per day using gmail's SMTP. Is there any SMTP service's that I can use instead?

  • Why does Event intent in android not return a result?

    - by dhaval
    I am creating a event using Intent intent = new Intent(Intent.ACTION_EDIT); intent.setType("vnd.android.cursor.item/event"); And invoking the intent using startActivityForResult(intent, Constants.LINK_CALENDER); There is nothing returned to call in onActivityResult(int requestCode, int resultCode, Intent data) It always returns data=null ie., returned intent result is always null. I am trying to retrieve the "Done/Revert" state of calender event just created and some identity so that i can open the event again in future from elsewhere in code.

    - by kknight

  • How can I send email attachment without using an additional library in Perl?

    - by CheeseConQueso
    Hey, I was wondering if there is a way to attach files (specifically .csv files) to a mail message in Perl without using MIME::Lite or any other libraries. Right now, I have a 'mailer function' that works fine, but I'm not sure how to adapt it into attaching files. Here is what I have: open(MAIL, "|/usr/sbin/sendmail -t"); print MAIL "To: cheese\@yahoo.com\n"; print MAIL "From: queso\@what.com\n"; print MAIL "Subject: Attached is $filename\n\n"; print MAIL "$message"; close(MAIL); I think this is specific for UNIX.

  • Android: roatating images in a loop.

    - by user573736
    Hello, I am trying with no success to modify the code example from: http://www.inter-fuser.com/2009/08/android-animations-3d-flip.html so it will rotate the images in a loop, when clicking on the image once. (second click should pause). I tried using Handler and threading but cannot update the view since only the main thread can update UI. Exception I get from the code below: android.view.ViewRoot$CalledFromWrongThreadException: Only the original thread that created a view hierarchy can touch its views. [in 'image1.startAnimation(rotation);' ('applyRotation(0, 90);' from the main thread)] package com.example.flip3d; import android.app.Activity; import android.os.Bundle; import android.view.View; import android.view.animation.AccelerateInterpolator; import android.widget.ImageView; public class Flip3d extends Activity { private ImageView image1; private ImageView image2; private boolean isFirstImage = true; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); image1 = (ImageView) findViewById(R.id.image01); image2 = (ImageView) findViewById(R.id.image02); image2.setVisibility(View.GONE); image1.setOnClickListener(new View.OnClickListener() { public void onClick(View view) { if (isFirstImage) { applyRotation(0, 90); isFirstImage = !isFirstImage; } else { applyRotation(0, -90); isFirstImage = !isFirstImage; } } }); } private void applyRotation(float start, float end) { // Find the center of image final float centerX = image1.getWidth() / 2.0f; final float centerY = image1.getHeight() / 2.0f; // Create a new 3D rotation with the supplied parameter // The animation listener is used to trigger the next animation final Flip3dAnimation rotation = new Flip3dAnimation(start, end, centerX, centerY); rotation.setDuration(500); rotation.setFillAfter(true); rotation.setInterpolator(new AccelerateInterpolator()); rotation.setAnimationListener(new DisplayNextView(isFirstImage, image1, image2)); if (isFirstImage) { image1.startAnimation(rotation); } else { image2.startAnimation(rotation); } } } How can I manage to update the UI and control the rotation within onClick listener? Thank you, Oakist

  • Maximum size of email X-Headers

    - by Spike Williams
    We are looking at sticking some metadata into the X-Headers of email messages. These emails are for consumption by internal systems, and will be hosted on an Exchange server. Is there a maximum size for the ammount of data that we can store in an X-Header? Are there any limitations, such as special characters, that I should know about?

  • Scrolling RelativeLayout- white border over part of the content

    - by Tanis.7x
    I have a fairly simply Fragment that adds a handful of colored ImageViews to a RelativeLayout. There are more images than can fit on screen, so I implemented some custom scrolling. However, When I scroll around, I see that there is an approximately 90dp white border overlapping part of the content right where the edges of the screen are before I scroll. It is obvious that the ImageViews are still being created and drawn properly, but they are being covered up. How do I get rid of this? I have tried: Changing both the RelativeLayout and FrameLayout to WRAP_CONTENT, FILL_PARENT, MATCH_PARENT, and a few combinations of those. Setting the padding and margins of both layouts to 0dp. Example: Fragment: public class MyFrag extends Fragment implements OnTouchListener { int currentX; int currentY; RelativeLayout container; final int[] colors = {Color.BLACK, Color.RED, Color.BLUE}; @Override public View onCreateView(LayoutInflater inflater, ViewGroup fragContainer, Bundle savedInstanceState) { return inflater.inflate(R.layout.fragment_myfrag, null); } @Override public void onActivityCreated(Bundle savedInstanceState) { super.onActivityCreated(savedInstanceState); container = (RelativeLayout) getView().findViewById(R.id.container); container.setOnTouchListener(this); // Temp- Add a bunch of images to test scrolling for(int i=0; i<1500; i+=100) { for (int j=0; j<1500; j+=100) { int color = colors[(i+j)%3]; ImageView image = new ImageView(getActivity()); image.setScaleType(ImageView.ScaleType.CENTER); image.setBackgroundColor(color); LayoutParams lp = new RelativeLayout.LayoutParams(100, 100); lp.setMargins(i, j, 0, 0); image.setLayoutParams(lp); container.addView(image); } } } @Override public boolean onTouch(View v, MotionEvent event) { switch (event.getAction()) { case MotionEvent.ACTION_DOWN: { currentX = (int) event.getRawX(); currentY = (int) event.getRawY(); break; } case MotionEvent.ACTION_MOVE: { int x2 = (int) event.getRawX(); int y2 = (int) event.getRawY(); container.scrollBy(currentX - x2 , currentY - y2); currentX = x2; currentY = y2; break; } case MotionEvent.ACTION_UP: { break; } } return true; } } XML: <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="fill_parent" android:layout_height="fill_parent" tools:context=".FloorPlanFrag"> <RelativeLayout android:id="@+id/container" android:layout_width="fill_parent" android:layout_height="fill_parent" /> </FrameLayout>

  • Android - what's the difference between the various methods to get a Context?

    - by Alnitak
    In various bits of Android code I've seen: public class MyActivity extends Activity { public void method() { mContext = this; // since Activity extends Context mContext = getApplicationContext(); mContext = getBaseContext(); } } However I can't find any decent explanation of which is preferable, and under what circumstances which should be used. Pointers to documentation on this, and guidance about what might break if the wrong one is chosen, would be much appreciated.

  • How do you iterate through each email in your inbox using python?

    - by djblue2009
    I'm completely new to programming and I'm trying to build an autorespoder to send a msg to a specific email address. Using an if statement, I can check if there is an email from a certain address in the inbox and I can send an email, but if there are multiple emails from that address, how can I make a for loop to send an email for every email from that specific address. I tried to do use this as a loop: for M.search(None, 'From', address) in M.select(): but I get the error: "can't assign to function call" on that line

  • Email SMTP validator

    - by Hrvoje
    I need to send hundreds of newsletters, but would like to check first if email exists on server. It's called smtp validation, at least i think so, based on my research on net. There's several libraries that can do that, and also a page with open-source code in asp (http://www.coveryourasp.com/ValidateEmail.asp#Result3), but I have hard time reading classic asp, and it seams that it uses some third-party library... Does someone have code for smtp validation in c#, and/or general explanation of how it works?

  • .NET Generate email text in Outlook from Word

    - by Chapso
    I am attempting to generate the body of an email in Outlook 2007 from the text of a Word 2007 document in VB. I have access to both the Word and Outlook object libraries, and I can read from the Word document to get a string and write it to Outlook, but I need to keep the formatting from the Word document intact. The purpose will be to allow users to edit the word document and always have the emails my program generates be in sync with the document. Does anyone know how to do this?
