Filter out Intents you don"t want to show from a IntentChooser dialog. For example your own app, competing apps or just apps you have a share integration by SDK already :) Based on http://stackoverflow.com/questions/5734678/custom-filtering-of-intent-chooser-based-on-installed-android-package-name/8550043#8550043

gistfile1.java

// Usage:
// blacklist
String[] blacklist = new String[]{"com.any.package", "net.other.package"};
// your share intent
Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("text/plain");
intent.putExtra(Intent.EXTRA_TEXT, "some text");
intent.putExtra(android.content.Intent.EXTRA_SUBJECT, "a subject");
// ... anything else you want to add
// invoke custom chooser
startActivity(generateCustomChooserIntent(intent, blacklist));

// Method:
private Intent generateCustomChooserIntent(Intent prototype, String[] forbiddenChoices) {
	List<Intent> targetedShareIntents = new ArrayList<Intent>();
	List<HashMap<String, String>> intentMetaInfo = new ArrayList<HashMap<String, String>>();
	Intent chooserIntent;

	Intent dummy = new Intent(prototype.getAction());
	dummy.setType(prototype.getType());
	List<ResolveInfo> resInfo = getPackageManager().queryIntentActivities(dummy, 0);

	if (!resInfo.isEmpty()) {
		for (ResolveInfo resolveInfo : resInfo) {
			if (resolveInfo.activityInfo == null || Arrays.asList(forbiddenChoices).contains(resolveInfo.activityInfo.packageName))
				continue;

			HashMap<String, String> info = new HashMap<String, String>();
			info.put("packageName", resolveInfo.activityInfo.packageName);
			info.put("className", resolveInfo.activityInfo.name);
			info.put("simpleName", String.valueOf(resolveInfo.activityInfo.loadLabel(getPackageManager())));
			intentMetaInfo.add(info);
		}

		if (!intentMetaInfo.isEmpty()) {
			// sorting for nice readability
			Collections.sort(intentMetaInfo, new Comparator<HashMap<String, String>>() {
				@Override
				public int compare(HashMap<String, String> map, HashMap<String, String> map2) {
					return map.get("simpleName").compareTo(map2.get("simpleName"));
				}
			});

			// create the custom intent list
			for (HashMap<String, String> metaInfo : intentMetaInfo) {
				Intent targetedShareIntent = (Intent) prototype.clone();
				targetedShareIntent.setPackage(metaInfo.get("packageName"));
				targetedShareIntent.setClassName(metaInfo.get("packageName"), metaInfo.get("className"));
				targetedShareIntents.add(targetedShareIntent);
			}

			chooserIntent = Intent.createChooser(targetedShareIntents.remove(targetedShareIntents.size() - 1), getString(R.string.share));
			chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, targetedShareIntents.toArray(new Parcelable[]{}));
			return chooserIntent;
		}
	}

	return Intent.createChooser(prototype, getString(R.string.share));
}

This line:

info.put("simpleName", String.valueOf(resolveInfo.activityInfo.loadLabel(getPackageManager())));

doesn't always produce the expected label. For example, when using Intent.createChooser() I normally have these options: "ES Save to..." and "Send by LAN". but the above code produces in both cases the label "ES File Explorer". Also, it produces "Picasa Uploader" instead of "Picasa". For Picasa, even the icon is wrong (the generic android icon). What can be done to produce the normal labels and icons in all cases?

Thanks! I made a Kotlin version => https://gist.github.com/Kevinrob/fef4359f68228ae0bcb803402e7715fa

Can anybody explain to me what is significance of this "targetedShareIntents.remove(targetedShareIntents.size() - 1)"
