I am checking to see if my app has a network connection Whenever I rotate my screen between landscape and portrait this method returns false. It makes me wonder if Network connections are getting killed during the rotation?

After reading the forums and changing settings and doing a few battery cycles, I had been getting really good battery life of at least two days on medium usage and 3 days on light with my connection not having any real issues. Then, 2 days ago I installed weatherbug and beautiful widgets. While I enjoy both, it seems like my network connection goes down fairly often now and I need to turn on wifi to check email or do anything else web related. Has anyone else lost their network connection and been able to narrow down the cause? I'm hoping it's not one of these two, but I can't imagine what else it would be.

View 2 Replies View RelatedI'm developing an App that sends keep-alive packets to its server to ensure the connection is still alive.
The server is java based and thus easily to run. I run the server on a virtual machine (Windows 7). After my App is connected and the first keep-alive packet is received (it displays a message in its console output) I disable the network interface in Windows. This step is very important because by disabling it, there is no way to send any packet back to the client informing it about network changes.
The clients are configured to send every 25 seconds a keep-alive packet, so you don't need to wait long.
When you use the sample JavaClient on Windows 7 it takes less than a minute after the keep-Alive packet and an exception is thrown which triggers reconnection (which currently can't occur). This is the expected behaviour.
When you use the sample Android App on an emulator (tested Android version 2 and 4) it is the same behaviour. So in less than a minute after the keep-alive packet it recognises that the connection is dead, throws an exception, this triggers reconnection.
Problem is now when this App runs on a real device (tested several, Xpearia Arc S, one Cyanogen Mod 4 on Galaxy S3 and my Galaxy S3). I've waited 5 minutes, but there was no exception. This behaviour is reproducable.
Since this is a sample App, it uses no wakelock or service, so to test it is important to have it in foreground all the time (don't switch to other Apps or homescreen) and increase your display timeout to a few minutes to ensure that it doesn't go off. Use Logcat-Output to get informed whats happening, because there is no output in the App itself.
Now Sample-Code is in the attachement. Something had gone wrong. The Code consists of 3 Eclipse projects which you can easily import.
You can use the 3G network for surfing the Internet and at the same time the wifi network to move files only?

Also how could I obtain the parent of an activity created in such a way ? Can a reference of the activity below the current activity in the activity stack be obtained ?
If my screen locks while I have a wifi connection, then the connection is lost when I unlock the phone.First, is this perhaps deliberate, to save power? Also, either way, when I unlock the screen and go into wifi settings, I see that the phone is trying to make a wifi connection, but it never succeeds, even though it's my home network and I'm in the same room as the router. It just states 'Obtaining address.
View 10 Replies View RelatedI have been looking at the ConnectivityManager class documented at http://developer.android.com/reference/android/net/ConnectivityManage... .
I would like to know if an Android application can open a network connection (socket) on a specified network interface [on a device supporting multiple network interface types WiFi, Cellular, WiMax etc] ? I am looking for the capability for an application to open a socket on a given type of network for example over WiFi network or over 3G Cellular Data network.
If this is possible in Android, how would I code this requirement within the API Framework ? The ConnectivityManager enables an application to learn about available network connections and currently categorises them as either TYPE_WIFI or TYPE_MOBILE.
There is a member function in the ConnectivityManager class called requestRouteToHost(int,int) [url] which "Ensure that a network route exists to deliver traffic to the specified host via the specified network interface. An attempt to add a route that already exists is ignored, but treated as successful." Sounds like this would install an IP routing table entry to reach a given host via a specified network interface type (WiFi or Mobile). After calling this would it be sufficient for an application to open a socket and connect to the desired destination address ?
Or perhaps the application needs to bind() a socket to a local address of a network interface of the desired type (WiFi or Mobile) Or by setting a socket-level socket option of SO_DONTROUTE ?
I'm looking for a way to provide to the Notification Manager an icon which was not statically created, but rather created at run-time by the application.
I want to write a very simple weather application, which shows the current conditions icon and temperature at the notification bar, all packed into a small icon. So, I would like to know how to superimpose text onto an icon, and how to display the new icon in the notification bar, which, as you know, takes resource ID only.
I have a ImageView acting as a top banner on top of a webview. The image of this banner is created in execution time dependending on the resolution of the device. The height of the banner is always the same for each resolution. The only thing that changes is the width, which changes according to the orientation. But, since the width changes and the height doesn't, I end up having sort of 2 images with different proportion. And this is way the scale down/up won't work out for me.
Another problem is that everytime the user rotates the screen, the banner image is created again but Android seems not to update the image and thus I have a banner missing part of it.
I thought about having a real big image that will fit for both landscape and portrait orientation. But this seems not to be a good idea since Android keeps resizing the image everytime so it will fit on the space of the ImageView.
I'm running out of ideas here. Can someone suggest something?
When i'm connected to my router at home via wifi, the connection randomly drops from time to time. My laptop and TV is fine which are both running via the internet. The setting is set to stay connected always, even when the screen goes black.
Does anyone have a resolution for this? Perhaps static IP? if this is the answer, what should the settings be?
I create a local file in my activity like this: How can I pass the URI of this file to another Activity? And do I need to set any permission (file permission, manifest permission) to allow other Activity to use that file?

I'm using an intent-filter on URLs for my activity:
CODE:...............
the launchMode attribute is set to "singleTop", but it looks like a new activity is created every time I click a matching url. I thought that if the activity is already alive somewhere, it would simply be brought to the front of my activity stack?
I tried this on the emulator/device, same behavior, a new activity instance is always created.
I am trying to apply an animation to a view in my Android app after my activity is created. To do this, I need to determine the current size of the view, and then set up an animation to scale from the current size to the new size. This part must be done at runtime, since the view scales to different sizes depending on input from the user. My layout is defined in XML. This seems like an easy task, and there are lots of SO questions regarding this though none which solved my problem, obviously. So perhaps I am missing something obvious. I get a handle to my view by: ImageView myView = (ImageView)getWindow().findViewById(R.id.MyViewID);
This works fine, but when calling getWidth(), getHeight(), getMeasuredWidth(), getLayoutParams().width, etc., they all return 0. I have also tried manually calling measure() on the view followed by a call to getMeasuredWidth(), but that has no effect. I have tried calling these methods and inspecting the object in the debugger in my activity's onCreate() and in onPostCreate(). How can I figure out the exact dimensions of this view at runtime?
I have an application where I navigate from Activity A to Activity B and back to A and then B. I want to resume the activity B (which has a Bundle passed to it ) from Activity A. The documentation says that OnSaveInstance() is called only when the activity is killed, so how do i use OnPause which does not have the Bundle to resume the activity B.
