List intent available android wear

I try to start activity from a watchface or a app android.
I able to start the view to choose watchface when user tap on watchface :
#Override
public void onTapCommand(
#TapType int tapType, int x, int y, long eventTime) {
Intent intent = new Intent(Intent.ACTION_SET_WALLPAPER));
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
}
I want start other activities like Google Agenda, Google fit, or other ...
It's possible to list all intents available on the device ?
Thanks

This will return all of the launcher activities on a device:
public static List<ResolveInfo> gatherApps(Context context) {
if(allApps == null) {
final PackageManager packageManager = context.getPackageManager();
final Intent mainIntent = new Intent(Intent.ACTION_MAIN, null);
mainIntent.addCategory(Intent.CATEGORY_LAUNCHER);
List<ResolveInfo> infoList = context.getPackageManager().queryIntentActivities(mainIntent, 0);
Collections.sort(infoList, new Comparator<ResolveInfo>() {
#Override
public int compare(ResolveInfo lhs, ResolveInfo rhs) {
return lhs.loadLabel(packageManager).toString().compareTo(rhs.loadLabel(packageManager).toString());
}
});
allApps = infoList;
}
return allApps;
}

Share image to only twitter by intent.action_send error

"com.handmark.tweetcaster", "com.thedeck.android" };
Intent tweetIntent = new Intent();
tweetIntent.setType("image/jpeg");
tweetIntent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(myFile));
final PackageManager packageManager = mContext.getPackageManager();
List<ResolveInfo> list = packageManager.queryIntentActivities(
tweetIntent,0);
for (int i = 0; i < twitterApps.length; i++) {
for (ResolveInfo resolveInfo : list) {
String p = resolveInfo.activityInfo.packageName;
if (p != null && p.startsWith(twitterApps[i])) {
tweetIntent.setPackage(p);
}
}
}
mContext.startActivity(tweetIntent);
}
How must I do.

create shortcut for thrid-party app, is that possible?

I use code below to create shortcut for my own app, and I wonder if I can create a shortcut for third-party app? If that's possible, Where could I get the icon(Parcelable)?
Intent shortcut = new Intent("com.android.launcher.action.INSTALL_SHORTCUT");
shortcut.putExtra("duplicate", false);
shortcut.putExtra(Intent.EXTRA_SHORTCUT_NAME, name);
shortcut.putExtra(Intent.EXTRA_SHORTCUT_ICON_RESOURCE, icon);
shortcut.putExtra(Intent.EXTRA_SHORTCUT_INTENT, new Intent().setComponent(new ComponentName(className, activity)));
context.sendBroadcast(shortcut);

public static void createShortcutForPackage(Context context, String packageName, String className) {
Intent intent = new Intent();
intent.setComponent(new ComponentName(packageName, className));
PackageManager pm = context.getPackageManager();
ResolveInfo ri = pm.resolveActivity(intent, 0);
String shortcutName = ri.loadLabel(pm).toString();
String activityName = ri.activityInfo.name;
int iconId = ri.activityInfo.applicationInfo.icon;
Context pkgContext = PackageUtil.createPackageContext(context, packageName);
if (pkgContext != null) {
ShortcutIconResource sir = Intent.ShortcutIconResource.fromContext(pkgContext, iconId);
installShortcut(pkgContext, packageName, activityName, shortcutName, sir);
}
}
public static void installShortcut(Context context, String packageName, String componentName, String shortcutName, Parcelable icon) {
Intent shortcut = new Intent("com.android.launcher.action.INSTALL_SHORTCUT");
ComponentName cn = new ComponentName(packageName, componentName);
shortcut.putExtra(Intent.EXTRA_SHORTCUT_INTENT, new Intent(Intent.ACTION_MAIN).setComponent(cn));
shortcut.putExtra(Intent.EXTRA_SHORTCUT_NAME, shortcutName);
shortcut.putExtra(Intent.EXTRA_SHORTCUT_ICON_RESOURCE, icon);
shortcut.putExtra("duplicate", false);
context.sendBroadcast(shortcut);
}
public static Context createPackageContext(Context context, String pkgName) {
Context result = null;
try {
result = context.createPackageContext(pkgName, Context.CONTEXT_IGNORE_SECURITY | Context.CONTEXT_INCLUDE_CODE);
} catch (NameNotFoundException e) {
Log.d(TAG, "createPackageContext(): " + e.getStackTrace());
}
return result;
}

Checking if Facebook is installed on Android

How can I check that? Do i have to use PackageManager? Thank you :D

I check it this way (check if the returned value is unequal to null):
public static Intent findFacebookClient(Context con)
{
final String[] FacebookApps = {"com.facebook.android", "com.facebook.katana"};
Intent facebookIntent = new Intent();
facebookIntent.setType("text/plain");
final PackageManager packageManager = con.getPackageManager();
List<ResolveInfo> list = packageManager.queryIntentActivities(facebookIntent, PackageManager.MATCH_DEFAULT_ONLY);
for (int i = 0; i < FacebookApps.length; i++)
{
for (ResolveInfo resolveInfo : list)
{
String p = resolveInfo.activityInfo.packageName;
if (p != null && p.startsWith(FacebookApps[i]))
{
facebookIntent.setPackage(p);
return facebookIntent;
}
}
}
return null;
}

final PackageManager pm = getPackageManager();
List<ApplicationInfo> packages = pm
.getInstalledApplications(PackageManager.GET_META_DATA);
for (ApplicationInfo packageInfo : packages) {
Log.d(TAG, "Installed package : " + packageInfo.packageName);
}
Then you can check if packageInfo.packageName is equal to some string which contains the package name of that application.

Get list of installed applications that can be launched

I have a custom listPreference I would like to display a list of apps that can be launched (contain an activity with CATEGORY_LAUNCHER). The selection will be used later to launch the application. When I did a search for the solution, the list also contained apps that could not be launched. Is there any way to narrow this down?
public class AppSelectorPreference extends ListPreference {
#Override
public int findIndexOfValue(String value) {
return 0;
//return super.findIndexOfValue(value);
}
public AppSelectorPreference(Context context, AttributeSet attrs) {
super(context,attrs);
PackageManager pm = context.getPackageManager();
List<PackageInfo> appListInfo = pm.getInstalledPackages(0);
CharSequence[] entries = new CharSequence[appListInfo.size()];
CharSequence[] entryValues = new CharSequence[appListInfo.size()];
try {
int i = 0;
for (PackageInfo p : appListInfo) {
if (p.applicationInfo.uid > 10000) {
entries[i] = p.applicationInfo.loadLabel(pm).toString();
entryValues[i] = p.applicationInfo.packageName.toString();
i++;
}
}
} catch (Exception e) {
e.printStackTrace();
}
setEntries(entries);
setEntryValues(entryValues);
}
}

Solved:
final Context context = getBaseContext();
final Intent mainIntent = new Intent(Intent.ACTION_MAIN, null);
mainIntent.addCategory(Intent.CATEGORY_LAUNCHER);
final List<ResolveInfo> pkgAppsList = context.getPackageManager().queryIntentActivities( mainIntent, 0);
CharSequence[] entries = new CharSequence[pkgAppsList.size()];
CharSequence[] entryValues = new CharSequence[pkgAppsList.size()];
int i = 0;
for ( ResolveInfo P : pkgAppsList ) {
entryValues[i] = (CharSequence) P.getClass().getName();
entries[i] = P.loadLabel(context.getPackageManager());
++i;
};

#Frazerm63 i think you are missing this thing in Your Code
Intent localIntent = new Intent("android.intent.action.MAIN", null);
localIntent.addCategory("android.intent.category.LAUNCHER");
List localList = localPackageManager.queryIntentActivities(localIntent, 0);
Collections.sort(localList, new ResolveInfo.DisplayNameComparator(localPackageManager));
you have to pass your PackageManager object in above code .means this localPackageManager
i have not much idea how you can use this in user Code but this will help to get you idea to filter only some category application.
