[mono-android] API 11/12

2011-05-13 Thread andi 
I am going to develop an application for tablets. So my question is how long
will it take until Mono for Android will support API 11 and API 12
respectively?

Thanks
Andi

[mono-android] App crashes

2011-07-28 Thread andi 
Hi my app crashes often when switching between activities. The logging
provides the following message:

InputDispatcher channel ….. ~ Consumer closed input channel or an error
occurred. Events= 0x8
InputDispatcher channel ….. ~ Channel is unrecoverably broken and will be
disposed!
Any ideas?

Best
Andi

There are two warnings:

InputManagerService Window already focused, ignoring focus gain of:
com.android.internal.view.IInputMethodClient$Stub$Proxy$@41337ce8

InputManagerService Window already focused, ignoring focus gain of:
com.android.internal.view.IInputMethodClient$Stub$Proxy$@4148e610

After the tow error messages (InputDispatcher) another error message is
logged:

InputDispatcher Received spurious received callback for unknown input
channel. fd=275, events=0x8

Re: [mono-android] App crashes

2011-07-28 Thread andi 
I am able to reproduce the error.

Following situation:

The layout of a list view row is defined as followed:



http://schemas.android.com/apk/res/android";
  android:layout_height="wrap_content" android:id="@+Id/row"
android:layout_width="match_parent" android:weightSum="15"
android:orientation="horizontal">







The linear layout (grid) has to be filled dynamic - it depends on the amount
of data items. Hence the view is produced somehow in the GetView method of
an adapter.

The view which is added to the linear layout is like a grid. A similar code
like the following is used to create this layout. This layout is added to
the linear layout (grid) of the list view row by calling AddView(layout);:


var layout = new LinearLayout(this.context)
{
Orientation = Orientation.Vertical, 
WeightSum = rows
};

for (int row = 0; row < rows; row++)
{
var view = new LinearLayout(this.context)
{
Orientation = Orientation.Horizontal, 
WeightSum = columns
};

var layoutParameters = new LinearLayout.LayoutParams(0,
ViewGroup.LayoutParams.MatchParent, 1f);

for (int i = 0; i < columns; ++i)
{
view.AddView(
new NoteTextView(this.context)
{
LayoutParameters = layoutParameters,
Gravity = GravityFlags.CenterHorizontal,
Text = "My text"
});
}

layout.AddView(view, row);
}


This code is executed several times but after some time it crashes at line
*layout.AddView(view);*. A try catch around this line does not work - no
exception. The application crashes with the log messages I posted before.

Did I make a mistake? Or is this a problem of Mono for Android? Does anyone
has any idea?

Andi

2011-08-06 Thread andi 
After investigated four days in finding the bug, I am quite sure that the
problem is the garbage collector. After some time (memory was allocated) I
tried to call the garbage collector - GC.Collect(). The result is - the
application crashes. It is reproducible. I will file a bug report at
bugzilla.xamarin.com.

Re: [mono-android] 1.9.2 Packaging - InvalidCastException

2011-10-29 Thread andi 
Hello,

I had the same problem. In my case I added in the AndroidManifest.xml file
attributes of the application like Label, Logo. However, I also implemented
that information as attributes of my application class and that is the
problem (twice the same attributes). So I am removed the attributes in the
AndroidManifext.xml file, but you can also remove the attributes of the
application class instead in the xml file, both works.

[mono-android] TaskScheduler.FromCurrentSynchronizationContext()

2011-11-14 Thread andi 
Hi folks,

I am trying to use the the SynchronizationContext in order to synchronize
background threads with the UI thread. There are a couple of similar
examples (cf. 
http://reedcopsey.com/2009/11/17/synchronizing-net-4-tasks-with-the-ui-thread/
link ) like this working with WPF and Winforms (here I use m4a):



Unfortunately, it does not work. The actions, which have to run on the UI
thread running on background threads and the button text is not updated.

Have anyone an idea?

Thank you Wally,

I know RunOnUIThread and of course that works. However I try to build a
platform independent library in which I can use the TaskScheduler.

Meanwhile I found a working solution for me:



I create the TaskScheduler as followed:
