Executing PowerShell script

1. Check your execution policy:
   PS> Get-ExecutionPolicy
2. The execution policy is "Restricted" by default
3. Change it to "Unrestricted"
   PS> Set-ExecutionPolicy Unrestricted
4. Then you can run your script
   e.g. PS> .\scriptfile.ps1

ESRI ArcGIS JS API version 3.4 hiding the Dojo Dnd style "dojoDndAvatar"

For ArcGIS JS API v3.4, if you include "esri.css" in your project, then your Dojo Dnd Avatar (the floating hints while you're doing drag and drop) will be disappeared.

Why? Because in "esri.css", esri.css got the following style:

     .dojoDndAvatar {display: none;}

God... What the hell ESRI guys are doing ?!

Avoid Android drawable resource to be scaled automatically

You know, you can have drawable images in Android (e.g. /res/drawable), you normally have it rescaled automatically according to your device dpi (e.g. ldpi, mdpi, hdpi, etc).

If you just don't want Android to scale it for, put your graphic files in /res/drawable-nodpi.

Customize your ACTION_CHOOSER Intent

For an Android Intent chooser, it is possible to either remove an Intent or add an custom Intent, this is how we do it:

List<Intent> targetedShareIntents = new ArrayList<Intent>();

Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("text/plain");
intent.putExtra(Intent.EXTRA_TEXT, "http://www.blogspot.com");

List<ResolveInfo> resInfo = this.getPackageManager().queryIntentActivities(intent, 0);

for (ResolveInfo resolveInfo : resInfo) {
   String packageName = resolveInfo.activityInfo.packageName;

   Intent targetedShareIntent = new Intent(android.content.Intent.ACTION_SEND);
   targetedShareIntent.setType("text/plain");
   targetedShareIntent.putExtra(Intent.EXTRA_TEXT, "http://www.blogspot.com");
   targetedShareIntent.setPackage(packageName);

   if (!packageName.equals("com.facebook.katana")) { // Remove Facebook Intent share
      targetedShareIntents.add(targetedShareIntent);
   }
  }

// Add my own activity in the share Intent chooser
Intent i = new Intent(this, NextActivity.class);
targetedShareIntents.add(i);

Intent chooserIntent = Intent.createChooser(
   targetedShareIntents.remove(0), "Select app to share");

chooserIntent.putExtra(
   Intent.EXTRA_INITIAL_INTENTS, targetedShareIntents.toArray(new Parcelable[]{}));

startActivity(chooserIntent);

Side notes on Android Dev

1. To make your subclassed ViewPager (android.support.v4.view.ViewPager) work, prepare both the constructors in your class:
• ViewPager(Context context)
• ViewPager(Context context, AttributeSet attrs)
2. In ActionBarSherlock, if you can't get the loading icon work, i.e. setSupportProgressBarIndeterminateVisibility( ) just got no effect at all, then you are very likely have a wrong Window class (android.view.Window) imported. You should include the ActionBarSherlock Window class instead.
• com.actionbarsherlock.view.Window

Activity com.android.internal.app.ChooserActivity has leaked IntentReceiver error

If you ever come up with the error using ChooserActivity with the Android emulator, you probably don't need to be worried.

It's basically because you only have a single choice to start the intent (e.g. send a message, choose a audio file, choose a picture, etc., in the emulator).

There is just no way to show you the option dialog, and the exception raised. Read the explanation in the following:

Android 2.2 SDK with strings.xml having multiple %s

When building the SearchableDictionary examples using 2.2 SDK, the strings.xml contains the following which fails the compilation:

<plurals name="search_results"> 
  <item quantity="one">%d result for \"%s\": </item>
  <item quantity="other">%d results for \"%s\": </item>
</plurals>

We need to change them to the following in order make it compiled:


<plurals name="search_results"> 
  <item quantity="one">%1$d result for \"%2$s\": </item>
  <item quantity="other">%1$d results for \"%2$s\": </item>
</plurals>

Quick notes on Dojo 1.8

Just a quick notes on dojo 1.8. For example, if I want to use the Color object in dojo. I will:

   var Color;

   require(["dojo/_base/Color"], function(c) {
      Color = c;
   });

Then I can use the variable Color after the initialization is done. Am I correct? Should it be used in another way? :-)
