[android-developers] Re: generating keypress
You have to use start() to execute instrumentation in its own thread.
This new thread will call onStart() where you can call your
sendKeyDownUpSync(int) method. If you are using this for testing
purposes only, you can create a separate test class that extends
ActivityInstrumentationTestCase2YourActivity and implement your
testing accordingly.

[android-developers] Re: MediaStore returning loop of images and not entire directory
Hi Jason,
Have you tried the updated version of my code (http://
mihaifonoage.blogspot.com/2009/11/displaying-images-from-sd-card-
in.html) ? I am curious if you'll encounter the same problem with it.
I am still using MediaStore, so you might. It would also be
interesting to know what is wrong with the above code. I remember
getting the same behavior on the emulator once, but I deleted the AVD,
created a new one, and could not reproduce it afterwards.
By the way, what phone are you using, and what version of the SDK do
you have on it?

What I need to figure out is how to grab that images URI so that I can
bind it to a simpleCursorAdapter. Does the image even have a URI

copying it to the file dir just reference the original image on the

[android-developers] Question regarding com.google.android.photostream.GridLayout
Hi, I have tried to extend the GridLayout class (http://code.google.com/p/ apps-for-android/source/browse/trunk/Photostream/src/com/google/ android/photostream/GridLayout.java) so as to make it scrollable, but with no success. In this regard, I tried initializing the scrollbars inside the GridLayout constructor but I get an unsupported operation exception saying Can't convert to dimension: type=0x10. In addition, in the xml layout file that uses the GridLayout class, I tried placing the FrameLayout (which has the GridLayout) inside a ScrollView but that causes the GridLayout cannot have UNSPECIFIED dimensions error message to be shown. I initially was using a GridView with an adapter, but I never got it to work 'smoothly'. When I changed the code and tried to use the addView(View view) method, the method is not supported, since it is encouraged the use of an adapter. Has anybody used the GridLayout class successfully with scrolling capabilities, or know how to implement them?

[android-developers] Re: Updating one view also causes another view to update
Thanks for the link String! I am trying to figure out what Drawable is shared between the Chronometer and my SecondView (which draws some bitmaps), but I cannot come with anything. Looking at my stack trace, there is nothing there to suggest anything similar. I will look more into that, but my feeling is that it might be another (though similar) problem.

[android-developers] Re: Updating one view also causes another view to update
@Mark I care because something needs to be drawn if the onDraw method is being called. If there are no actual changes to the view, then this is a waste of resources (probably unnoticeable) and I need to deal with this case specifically, which complicates my application logic a little (here though it is probably my fault - not a perfect design). @skink You are right, there is an issue with the layout, but while I can get it to work and not have onDraw called every second, the views are not displayed as I want to. I will play around with this layout issue some more and see if I can get a fix. Beside all this, I do find it unnecessary; characters representing numbers from 0 to 9 have the same height, so the layout height (which is set to wrap_content) should not change.

Your View should not care about how many times it is drawn. Relying on assumed behavior (e.g., onDraw() is only called in certain scenarios) is not safe. Otherwise, your code may break in future Android releases where your assumption is no longer valid. You are certainly welcome to figure out how to avoid onDraw() unnecessarily, but you really need to implement support for onDraw() occurring when you are not necessarily expecting it. That is what I ended up doing. I just found everything to be curious to say the least. Thank you all for the feedback!

[android-developers] Strange behavior when loading images from SDCard
Hi,
I have an activity that loads and displays images from the SDCard. I
create a new AVD, specify the desired image of the sd card (which has
all my pictures already loaded), specify that AVD for deployment, and
start the application. I noticed a strange behavior. At first, the
images are not loaded; the getView method is never called, although
the constructor of my adapter is called. If I close the application,
and open the Gallery app that comes pre-installed, I see that the sd
card folder has the correct number of images, and it 'displays' the
first four. If I start my application again, those four images are
displayed, and only those. If I go back to the Gallery application,
open the sd card folder so that it loads all images, and restart my
application, all images are successfully displayed. Any reason why
this happens? I am using version 1.6, and (part of) my code is below:
[code]
// Set up an array of the Thumbnail Image ID column we want
String[] projection = {MediaStore.Images.Thumbnails._ID};
// Create the cursor pointing to the SDCard
cursor = managedQuery
( MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI,
projection,
null,
null,
MediaStore.Images.Thumbnails.IMAGE_ID);
// Get the column index of the Thumbnails ID
columnIndex = cursor.getColumnIndexOrThrow
(MediaStore.Images.Thumbnails._ID);
sdcardImages = (GridView) findViewById(R.id.sdcard);
//new LoadImagesFromSDCard().execute();
imageAdapter = new ImageAdapter(getApplicationContext());
sdcardImages.setAdapter(imageAdapter);
[/code]
Thank you,

[android-developers] Re: Strange behavior when loading images from SDCard
Actually, the behavior is not strange at all; there are no thumbnail
images on the sd card. When loading the images for the first time,
Android creates thumbnails for those images.

[android-developers] Manifest Editor - Application tab shows empty page
I started playing around with the Android Editors, so I wrote a simple Todo List application (taken from a book), and I opened the AndroidManifest.xml file using the Manifest Editor. My problem is that the Application tab shows an empty page. All other tabs work correctly. I have the ADT and the Android Editors plugins installed on both Eclipse 3.4.1, and Eclipse JEE 3.3.2. I tried reinstalling the plugins but I get the same results. In the past I have not used Android Editors at all, but I can see their utility know. The AndroidManifest.xml file is shown below: ?xml version=1.0 encoding=utf-8? manifest xmlns:android=http://schemas.android.com/apk/res/android; package=todolist android:versionCode=1 android:versionName=1.0.0 application android:icon=@drawable/icon android:label=@string/ app_name activity android:name=.ToDoList android:label=@string/app_name intent-filter action android:name=android.intent.action.MAIN / category android:name=android.intent.category.LAUNCHER / /intent-filter /activity /application /manifest Any ideas why the empty page for the Application tab?

[android-developers] Displaying already existing activities
Hello everyone, I am trying to display activities that were already created but are currently in the background. The problem is that I use startActivity or startSubActivity from the current activity to display them, which will create a new instance of the background activity. When calling finish on this new instance, I would want all instances of that activity to be closed, which is not the case. I could use launchMode=singleInstance in the manifest file, but I don't like how the transition is done between different activities (i.e., when starting a new activity from my single instance one, an empty screen is displayed, then the single instance activity is displayed again for a couple of seconds, then the new (map) activity is shown -- this only happens when displaying a map activity). If I don't use single instance on my original activity, the transition is done smoothly. I tried using an approach mentioned in a previous thread, where I first have to get the task id for the activity and use that when trying to bring it to the foreground, but I get the same task id for every activity that I create. Single instance would have solved that also, but as mentioned above, I dislike the screen transition process. It would have been nice to be able to get a list of all existing (background) activities and close them manually, but I don't think it's possible. If I call finish() write after I start a new activity, an intermediate screen appears before showing the new activity, which I dislike also. I am implementing the whole onActivityResult concept, but this goes to waits (at least in my case) when more than one instance of an activity is running, since I want all instances to be closed when one is. Hence, exiting the application has become more cumbersome. How can I solve this problem?
