Re: [mono-android] Available images list is empty on starting emulator dialog

[Mike Child]

After you install all the sdk software you still need to create an
emulator image to use. Go to the following link and towards the bottom
it shows how to create a emulator device...
http://docs.xamarin.com/android/getting_started/installation/Installation_for_Windows

Re: [mono-android] howto install / move apk on sdcard

I believe it is because of this.android:minSdkVersion="7"  Install
to SD wasn't added until API 8(I think). I know it didn't exist in 7.

Re: [mono-android] Disk Full error while copying DB to emulator

[Mike Child]

Check to see how much space is available on your device. If your app & data
is being deployed to your internal memory and not an SD card you may
actually be out of space.

Re: [mono-android] Debugging in VS2010 is unusable!

[Mike Child]

That's pretty much the way it is if you are using the emulator. Not really
anything you can do about it. The android emulator is notoriously slow and
google admits it. It has nothing to do with monodroid. Google is emulating
the arm instructions so it is much closer to the the phone architecture
where as the iPhone simulator is compiled as an x86 app.

Re: [mono-android] Honeycomb Emulator and "Hello World"

[Mike Child]

Try this suggestion that Jonathan Pryor said in a previous posting.

Mono for Android provides two runtimes (VS: Project Properties > Application
tab > Supported architectures), armeabi and armeabi-v7a.

The armeabi architecture is for ARMv5, which has no notion of multi-procesor
support.

The armeabi-v7a architectures is for ARMv7a, which does have a notion of
multi-processor support (and hardware FPU support, and...).

By default, only armeabi is included with your app, meaning that the armeabi
runtime will be used everywhere. However, the armeabi runtime appears to
crash (hard!) on multi-processor systems. For example, if I take the project
attached tohttp://bugzilla.xamarin.com/show_bug.cgi?id=245, comment out the
GC.Collect() call on line 39 (as described in Comment 2), and deploy a
Release build to a Xoom, it crashes in the manner you described.

If I rebuild a Release build and include the armeabi-v7a architecture, it
runs normally.

So is there a bug here? Yes: armeabi shouldn't crash on multi-core
architectures. (We should instead modify it so that it'll only run code on a
single core.) This has been filed as
http://bugzilla.xamarin.com/show_bug.cgi?id=281.

Is there a workaround? Yes: include the armeabi-v7a architecture with your
app.

Re: [mono-android] ZXing port to mono for Android

[Mike Child]

If you already have the app "Barcode Scanner" (made by zxing) then reading
barcodes can be as simple as passing an Intent to their app.

  Intent intent = new Intent("com.google.zxing.client.android.SCAN");
  intent.setPackage("com.google.zxing.client.android");
  StartActivityForResult(intent,0);

[mono-android] Failed to get device space on disk using MonoDevelop

[Mike Child]

I'm having trouble trying to run/debug and application on my device(Epic
4G). I am using MonoDevelop 2.8 and Mono 4 Android 1.9.1 on a MacBook Pro.

When I try the Run & Debug commands this is the error I'm getting when it
tries to Deploy to Device.
Not enough space on install location. Failed to get device space on disk.

This happens with any app I try, even the sample button click app. For
internal device storage I have 271 MB available and an SD card with 13 GB
free.

For further testing, everything works correctly in MonoDevelop when I use my
Galaxy Tab. On That device I have over 1 GB of internal device storage free.
When I'm on my Windows computer and use Visual Studio, the apps run and
debug correctly on both devices.

Has anybody seen this before or have any things to look for. I have looked
in logcat and nothing stands out as being abnormal.

Re: [mono-android] VS not recognizing Samsung GALAXY Tab

[Mike Child]

My Tab also works fine in Windows 7. I did not have download any drivers to
get it to work. As someone else said, make you have the Tabs usb debugging
turned on. If you can see it in mass storage mode, then usb debugging is
probably not on, our not working.
One thing I have noticed on my Tab though is that the usb debugging keeps
turning off on its own after a certain amount of time.

Re: [mono-android] debugging in Visual Studio w/ 1.9.1

[Mike Child]

I have also noticed the issue when starting the debug, the app deploys, but
never starts. Usually I deploy the app first then I hit debug. I have not
had the problem since when doing it like that. It seemed to happen the most
when I make code changes and hit debug. I don't remember it ever happening
yet if I hit debug, but have not made any code changes.

Re: [mono-android] Custom IListAdapter works on 1.9.0, fails on 1.9.1

[Mike Child]

If this is similar to a situation I had then you also need to inherit from
Java.Lang.Object. This will implement the Handle property for you. In
researching my issue I was told that you should never implement the Handle
property yourself. So I believe it should go something like this...

class YourListAdapter : Java.Lang.Object, IListAdapter

Hope that helps

Re: [mono-android] Webservice Deserialization Error

[Mike Child]

This may or may not be any help for you, but could be something to look
into/test. In your webservice are you passing any DateTime objects back to
they client?

My setup is a bit different. I'm using WCF that is returning json. I'm just
using httpwebrequest to hit my services and then I deserialize the object in
MonoDroid. It was always crashing on me until I removed the DateTime object.
Haven't found a way around it yet as it wasn't an important field so I
haven't looked into it.

So like I said, my setup is different but it may be something to test.

You would use DataContractJsonSerializer. It is under the
System.Runtime.Serialization.Json namespace.

Re: [mono-android] Passing information between tabs

[Mike Child]

Multiple inheritance is not possible. But looking at the msdn example, it's
implementiing INotifyPropertyChanged, which is an interface. You can
implement multiple interfaces.

Are you sure the phone and computer our on the same network and subnet. If
they are then check the firewall on you're computer. There should be no

checkout.

Re: [mono-android] HTTPs problems

[Mike Child]

The first time I tried this it was on an actual device, but I just tried
again on the emulator just to make sure it wasn't something goofy with that
and it still worked.

 var wc = new WebClient ();
 var test2 = wc.DownloadString("https://www.google.com";)

So it could be a bug in the version 1.2.2 of MonoDroid(which is the current
release version). Being on the 1.9.2 beta version it does work. As far as
getting the beta version, I don't know that you can without having a
license. Hopefully someone with more knowledge on that could answer for you.

Re: [mono-android] Being driven insane....

[Mike Child]

I found this code through some searching. I am using json in my code
but using xml should be relatively simple change in the code.

public static byte[] ToJson(T instance)  --> it's converted to
byte[] because i'm using it in httpwebrequest, you could just return
the string.
{
  DataContractJsonSerializer ser = new
DataContractJsonSerializer(typeof(T));
  MemoryStream ms = new MemoryStream();
  ser.WriteObject (ms,instance);
  String json = Encoding.UTF8.GetString (ms.ToArray ());
  return UTF8Encoding.UTF8.GetBytes (json);
}

public static T FromJson(string json)
{

  DataContractJsonSerializer ser = new
DataContractJsonSerializer(typeof(T));
  using(var tempStream = new MemoryStream(Encoding.UTF8.GetBytes (json)))
return (T)ser.ReadObject(tempStream);

}

Re: [mono-android] App Crashes on Samssung Galaxy SGH-1897 - Uncatchable Exception thrown by mono

[Mike Child]

I'm not sure if this is the issue or not but from the device specs I
take it that they device is running Android 2.1. There is a known
issues with 2.1 where Samsung release a broken kernel. The following
text is taking from the Xamarin web site

"Warnings
Warning: Samsung shipped a broken kernel with Android 2.1, which is
not able to support JIT compilation. If you possess a Galaxy-class
device with Android 2.1, you will get unexpected results, this is
caused by a kernel bug that breaks cache coherency, rendering any
engine doing JIT compilation useless. Check with your
manufacturer/carrier for an Android 2.2 update."


Since I see some calls to Reflection.Emit, this may be this issue.
Hopefully someone better at reading the log and more knowledgeable
than me can help answer.

Re: [mono-android] MonoDroid 4.0.1, APP Crash when debugging

Do you have the HTC sync software installed on your computer? If you
do that could be the issue.

Re: [mono-android] Using DatePickerDialog

[Mike Child]

yes, the month value is 0 based, so 12 is not valid. You would want to use 11.

Re: [mono-android] Gesture listener subclass no longer works with V4

[Mike Child]

Like Tomasz said, Inherit from Java.Lang.Object. You should never
implement the Handle property yourself.
