[android-developers] WiFi Direct connections drop during Bluetooth scan
Hello, I made an application (for work, not for public use) that constantly runs a bluetooth scan to detect any nearby devices. The next phase of the application was to connect a few android devices together so that could share the data they receive, to do this we purchased 3 Samsung Tabs to connect them via WiFi Direct. The problem is the WiFi Direct connections ALWAYS drop when my application is running (specifically running the bluetooth scan). When I do not run the bluetooth scan the WiFi Direct connections have not disconnected. Does anyone have any information that could help me here? Am I just out of luck and a bluetooth scan will always cause a WiFi Direct disconnect?

[android-developers] Re: WiFi Direct connections drop during Bluetooth scan
Thank you for the response. A constant bluetooth scan is necessary, that is what the application is designed to do - constantly detect nearby bluetooth devices. If your concern is battery drain well we have purchased numerous external power packs which will be able to power this for days. If there is another concern I am not aware with a constant scan please do share. A single scan does not cause a drop, no. The application I designed calls startDiscovery() every time the discovery is finished (unless manually stopped) to keep it constant. To verify my suspicion that bluetooth discovery was causing the drops I connected the devices via WiFi Direct, navigated to Android's bluetooth settings on the device and manually tapped Scan every time it finished. Sure enough one of the connections dropped off after about 8 consecutive scans. I am using a Samsung Galaxy Tab 2 10.1 as the WiFi Direct group owner, and 2 Samsung Galaxy Tab 2 7.0 tabs which should send data to the group owner. The 7.0 devices are running the scans.

[android-developers] Setting Background Image of View with onDraw Creates Finger Lag

[android-developers] 'E-Mail Developer' button creating a lot of spam?
Hello, I added an E-Mail Developer button to my application and ever since I get random e-mails throughout the day that either have an empty message body or just one or two words in a different language (looks like Russian or something similar, sometimes an Asian language). Occasionally I get one that just reads Good. At first I thought it was just a user complimenting me, but its happened to much to be a coincidence. For what its worth, just last night I updated to version X and already the e-mails I receive are from that version, barely 24 hours old. I'm worried this means my app has been hacked and decompiled.. but thinking about it more logically I'm not getting just extra general spam as if my e-mail had been 'stolen' and spread around, it's all originating from the E-mail Developer button. Plus, my app is barely equivalent in status to Angry Birds so I cant imagine it being at the top of a hackers To Do list. Is anyone else having this problem? If not, and you have an contact button installed, how did you set it up? Maybe I went about it the wrong way.. Thank you for your help!

Romain Guy states There's a compilation phase to embed extra information inside the PNG but it happens in aapt when the apk is built.. Since I need to create 9patch images after apk packaging, it looks like I need to replicate what the aapt does.

There's more info on the 9-patch at this linkhttp://developer.android.com/guide/topics/graphics/2d-graphics.html#n..., so you can know which pixels you want to set as black and which to keep clear. Here's the big caveat: I've never done this programmatically, but I have drawn all my 9-patch images by hand in the GIMP setting the 9 patch pixels myself, so I don't think it'd be too hard to do in code.

I was looking at 9patch because the images are being displayed on a home screen widget. They are designed for portrait display, so when orientation is changed to landscape the widget looks a bit distorted. If 9patch on device is possible that seems like the most efficient method, however if there is a way to detect orientation change in a home screen widget I would certainly accept that as the next best thing.

[android-developers] Creating 9-patch Images on Device
Hello, I am trying to create 9-patch images using bitmaps on the device.

I had the same error as well. startManagingCursor() was used in Activity A which launched Activity B. When Activity B was saved and Activity A returned to the forefront the app force closed. Calling stopManagingCursor() in Activity A solved it. Obviously my fault for not reading enough, but when I was learning the Android SDK and reading the dev guides I remember learning you should use startManagingCursor() so that the Cursor will be managed by the OS, implying nothing else was needed. Interesting that is not so! Matt. On Mar 3, 10:09 am, al achim.leub...@googlemail.com wrote: I saw the same error.

[android-developers] Undo Feature in Drawing App - Need best methodology, not looking for code
Hello, My application includes a drawing feature and I would like the add the ability to undo. The undo feature currently in place simply loads the bitmap from the last saved file, so no matter how many changes they make to their drawing undo will revert it back to the way it was before any changes were made. What I want to do now is make it more like the undo feature we are used to in modern applications, so that it does not go back to the way the file was when we first opened it, rather it goes back in various steps during our editing (which can be quite numerous). My idea is to save the current bitmap in a linked list after every occurrence of finger down, finger up. Thus every time the user lifts their finger from the screen the bitmap will be added to the linked list. Then of course when undo is selected the bitmap at the top of the stack will be loaded. The only problem is if the user makes 20, 30, 40+ changes to their drawing that is a lot of bitmaps to keep references to, am I right? I see out of memory errors coming. Any ideas for alternatives?

[android-developers] Hide Background ImageView from above Bitmap/Canvas
Hello,
I have an ImageView whose background is set to a drawable using
setBackgroundDrawable. On top of this ImageView is a custom view which
utilizes a Bitmap to allow the user to draw/paint. Currently the
Bitmap captures the background drawable so that every time the
onDraw method is called (which is frequently) the Bitmap with the
background image drawn onto it are constantly redrawn on the screen
thus creating a lot of lag (the tail of the paint is slow following
the user's finger).
protected void onDraw(Canvas canvas) {
canvas.drawBitmap(mBitmap, 0, 0, mBitmapPaint);
canvas.drawPath(mPath, mPaint);
}
So what I am trying to do is hide the ImageView from the Bitmap so
that it does not get captured. I want the ImageView to display so
the user sees it but not be drawn onto the Bitmap. How can I hide the
background drawable from the Bitmap?
I tried ImageView.setWillNotCacheDrawing(true) and
ImageView.setWillNotDraw(true) to no avail.
Any help would be greatly appreciated!
Matt.

paint_layout.xml

Hello,
My current painting activity is built off of FingerPaint.java from the

android:layout_width=fill_parent
android:layout_height=fill_parent /
!-- other buttons and text --
/FrameLayout
Can anyone inform me of why exactly? Am I missing an attribute for the
custom layout in the xml?
Thank you!
Matt.

[android-developers] Re: Redrawing Widget When Changing Orientation
I've discovered the method call that causes the problem but I still
don't understand why..
In an activity, after saving and exiting I make a static method call
MyAppWidget.forceUpdate(this, text);
Below is the method which updates the text of the widget
public static void forceUpdate(Context context, String note)
{
if (context != null)
{
ComponentName thisWidget = new
ComponentName(context,WhiteboardWidget.class);
AppWidgetManager manager =
AppWidgetManager.getInstance(context);
RemoteViews views = new
RemoteViews(whiteboard,R.layout.widget_layout);
views.setTextViewText(R.id.boardNote, note);
manager.updateAppWidget(thisWidget, views);
}
}
Any ideas now??

[android-developers] Redrawing Widget When Changing Orientation
Hello, I have a widget set up and it displays properly in both portrait and landscape when added to each. But when I change orientation it has the problem Problem Loading Widget. I delete this, re-add the widget, and it displays correctly. Thus, my widget can support both portrait and landscape but it doesn't survive an orientation switch. What am I missing? Do I need to redraw the widget when orientation is changed? Doesn't it do this automatically? Do I need to call onUpdate() somehow? Thank you!
