You're required to select a category for your application. On December 22, 2010, the available category types changed in the Developer Console. The original categories were renamed, merged, or split into new categories. We believe this will enhance the user experience significantly; the new categories will rolling out to users over the course of a week.

Moreover I am not one of top developers nor any of my apps have been promoted by Android Market. I am just an one among of thousands of Android developers with not to well known apps. And what may be really surprising all my apps are free as Google do not allow developers from my country (Poland) to sell apps via Android Market!

So keep in mind these facts: None of my apps has been ever promoted in Top of Android Market I am providing only free apps (mostly due of Android Market limitations) Even if I would be able to sell apps I would not use it as main income source… (I believe that you still can make more from ads…)

Current Instapaper and former Tumblr developer Marco Arment wonders out loud if Google Android phones can ever achieve the levels of usability and polish Apple’s iPhone has arguably had since day one

Android will continue to exhibit what Google does best: great low-level engineering and tight integration with Google’s other services. But it’s never going to be Apple-like in user experience, polish, or design. Attention to detail, like most facets of truly good design, can’t be (and never is) added later. It’s an entire development philosophy, methodology, and culture

The question is: How do I reference the Android default icons? In XML this would be: android:icon="@android:drawable/ic_menu_info_details

android.R.drawable.ic_menu_info_details

Apple tends to do that a lot. It’s deeply ingrained in their culture, priorities, and product development practices. In brief, their philosophy seems to be to ship only what’s great and leave out the rest. That’s why, instead of having a bad copy-and-paste implementation for the iPhone’s first two years, we just didn’t have one at all

Android as a platform, both in hardware and software, doesn’t reflect this. Nearly every hardware and software release has major shortcomings or rough edges. Many details and design decisions are lacking, wrong, or inexplicable. Neither Google nor the current Android device manufacturers embody the part of Apple’s culture that allows them to release a great product on day one. They have a different pattern: It’s always getting better. We’re always supposedly one or two releases from it being really great.

I never make technology-buying decisions based on future promises, rumors, or potential. I let other people be the bleeding-edge extremely early adopters, and I stick with what I know will work and stay out of my way. I don’t buy things that are “getting better”, because they usually don’t. Whatever caused them to be lacking in their current release will usually prevent them from being great in future releases. I buy things that are great today. They’re usually things that have been great since day one. And, more often than not, they’re Apple products.

Intent picMessageIntent = new Intent(android.content.Intent.ACTION_SEND);  picMessageIntent.setType("image/jpeg");    File downloadedPic =  new File(      Environment.getExternalStoragePublicDirectory(      Environment.DIRECTORY_DOWNLOADS),      "q.jpeg");    picMessageIntent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(downloadedPic));  

Path for me should have been file:///sdcard/DumbDumpers/DumbDumper.jpg

So in my example you need: emailIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse("file://"+ sPhotoFileName));

PhoneGap is an open source development framework for building cross-platform mobile apps. Build apps in HTML and JavaScript and still take advantage of core features in iPhone/iPod touch, iPad, Google Android, Palm, Symbian and Blackberry SDKs.

This article describes a technique you can use to find out whether the system contains any application capable of responding to the intent you want to use. The example below shows a helper method that queries the system package manager to determine whether there's an app that can respond to a specified intent. Your application can pass an intent to the method and then, for example, show or hide user options that the user would normally use to trigger the intent.

/** * Indicates whether the specified action can be used as an intent. This * method queries the package manager for installed packages that can * respond to an intent with the specified action. If no suitable package is * found, this method returns false. * * @param context The application's environment. * @param action The Intent action to check for availability. * * @return True if an Intent with the specified action can be sent and *         responded to, false otherwise. */public static boolean isIntentAvailable(Context context, String action) {    final PackageManager packageManager = context.getPackageManager();    final Intent intent = new Intent(action);    List<ResolveInfo> list =            packageManager.queryIntentActivities(intent,                    PackageManager.MATCH_DEFAULT_ONLY);    return list.size() > 0;}

@Overridepublic boolean onPrepareOptionsMenu(Menu menu) {    final boolean scanAvailable = isIntentAvailable(this,        "com.google.zxing.client.android.SCAN");    MenuItem item;    item = menu.findItem(R.id.menu_item_add);    item.setEnabled(scanAvailable);    return super.onPrepareOptionsMenu(menu);}

The Android Market engineering team has been hard at work on improving the Android Market experience for users and developers. Today, I’m pleased to announce a significant update to the Android Market client. Over the next two weeks, we’ll be rolling out a new Android Market client to all devices running Android 1.6 or higher.This new Market client introduces important features that improve merchandising of applications, streamline the browse-to-purchase experience, and make it easier for developers to distribute their applications.

To make it easier for developers to distribute and manage their products, we will introduce support for device targeting based on screen sizes and densities, as well as on GL texture compression formats. We are also increasing the maximum size for .apk files on Market to 50MB, to better support richer games.

To streamline the browse-to-purchase experience, users can now access all the information about an application on a single page without the need to navigate across different tabs.
