Get original app name without localize

I need get app's names but without local language, only in original language.
I'm from Poland and I need apps names list in original ENGLISH!
I have that code:
final PackageManager packageManager = context.getPackageManager();
final Intent intent = new Intent("android.intent.action.MAIN");
intent.addCategory("android.intent.category.LAUNCHER");
final List<ResolveInfo> activities = packageManager.queryIntentActivities( intent, 0 );
final int size = activities.size();
for (int i = 0; i < size; i++){
final ResolveInfo info = activities.get(i);
final String label = info.loadLabel(packageManager).toString();
final String pkgName = info.activityInfo.packageName;
final String className = info.activityInfo.name;
Log.d("INFO", label);
}

You can use getResourcesForApplication() from package manager. You can set resource culture and get values.
Please check the code below
PackageManager packageManager = getPackageManager();
final String packageName = "com.android.wallpaper.livepicker";
try {
ApplicationInfo applicationInfo = packageManager.getApplicationInfo(packageName, PackageManager.GET_META_DATA);
if (null != applicationInfo) {
CharSequence label = packageManager.getApplicationLabel(applicationInfo);
Log.d("MyTag", "Default app label is " + label);
Configuration configuration = new Configuration();
configuration.setLocale(new Locale("en"));
Resources resources = packageManager.getResourcesForApplication(packageName);
resources.updateConfiguration(configuration, getBaseContext().getResources().getDisplayMetrics());
String localizedLabel = resources.getString(applicationInfo.labelRes);
Log.d("MyTag", "Localized app label is " + localizedLabel);
}
} catch (PackageManager.NameNotFoundException e) {
Log.e("MyTag", "Failed to obtain app info!");
}

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.

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.

How to display list of application names from package names

I am developing an application which show all current applications. I am getting the apps package names, thats good but not specific applications name How should I do it, I am using following code:
Context context = this.getApplicationContext();
ActivityManager mgr = (ActivityManager)context.getSystemService(ACTIVITY_SERVICE);
List<RunningTaskInfo> tasks = mgr.getRunningTasks(30);
List<ActivityManager.RunningAppProcessInfo> tasksP = mgr.getRunningAppProcesses();
int numOfTasks = tasks.size();
for(int i = 0; i < numOfTasks; i++){
ActivityManager.RunningAppProcessInfo task = tasksP.get(i);
PackageInfo myPInfo = null;
try {
myPInfo = getPackageManager().getPackageInfo(task.processName, 0);
} catch (NameNotFoundException e) {
e.printStackTrace();
}
Toast.makeText(location.this,
task.processName,
Toast.LENGTH_LONG).show();
}
Also please tell me how to display these apps name in check boxes, so that I can kill my desired app.

Try this code for getting Installed Application in your phone :
final Intent mainIntent = new Intent(Intent.ACTION_MAIN, null);
mainIntent.addCategory(Intent.CATEGORY_LAUNCHER);
final List<ResolveInfo> pkgAppsList = this.getPackageManager().queryIntentActivities( mainIntent, 0);
List<String> componentList = new ArrayList<String>();
for (ResolveInfo ri : pkgAppsList) {
if (ri.activityInfo != null) {
String app_name=ri.activityInfo.loadLabel(getPackageManager()).toString();
Log.d("Apps Name", ""+ri.activityInfo.loadLabel(getPackageManager()).toString());
}
}
}

Installed Application Details

Intent filter = new Intent(Intent.ACTION_MAIN);
filter.addCategory(Intent.CATEGORY_LAUNCHER);
Context context = getApplicationContext();
PackageManager manager = getPackageManager();
List<ResolveInfo> infos = getPackageManager().queryIntentActivities(filter,0);
List<Intent> filters = new ArrayList<Intent>();
filters.add(filter);
ComponentName component = new ComponentName(context.getPackageName(), MainActivity.class.getName());
List<ComponentName> activities = new ArrayList<ComponentName>();
//ComponentName[] components = new ComponentName[] {new ComponentName("//com.neo.application", "com.neo.application.Application"), component};
try {
manager.getApplicationInfo(//PACKAGE_NAME);//just Ctrl+space it u'll get the package names.
} catch (NameNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

How do I start another application (downloaded or preinstalled) from an activity?

Basically, I want to get a list of all installed apps and pick one to run from an activity.
I've tried ACTION_PICK with Intents but that seems to leave out apps that were downloaded and it has a bunch of junk in it.
Thanks

// to get the list of apps you can launch
Intent intent = new Intent(ACTION_MAIN);
intent.addCategory(CATEGORY_LAUNCHER);
List<ResolveInfo> infos = getPackageManager().queryIntentActivities(intent, 0);
// resolveInfo.activityInfo.packageName = packageName
// resolveInfo.activityInfo.name = className
// reusing that intent
intent.setClassName(packageName, className);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED);
startActivity(intent)
Hope that's enough to help you figure out.

final File favFile = new File(Environment.getRootDirectory(), DEFAULT_FAVORITES_PATH);
try {
favReader = new FileReader(favFile);
} catch (FileNotFoundException e) {
Log.e(LOG_TAG, "Couldn't find or open favorites file " + favFile);
return;
}//gives the path for downloaded apps in directory
private void loadApplications(boolean isLaunching) {
if (isLaunching && mApplications != null) {
return;
}
PackageManager manager = getPackageManager();
Intent mainIntent = new Intent(Intent.ACTION_MAIN, null);
mainIntent.addCategory(Intent.CATEGORY_LAUNCHER);
final List<ResolveInfo> apps = manager.queryIntentActivities(mainIntent, 0);
Collections.sort(apps, new ResolveInfo.DisplayNameComparator(manager));
if (apps != null) {
final int count = apps.size();
if (mApplications == null) {
mApplications = new ArrayList<ApplicationInfo>(count);
}
mApplications.clear();
for (int i = 0; i < count; i++) {
ApplicationInfo application = new ApplicationInfo();
ResolveInfo info = apps.get(DEFAULT_KEYS_SEARCH_LOCAL);
application.title = info.loadLabel(manager);
application.setActivity(new ComponentName(
info.activityInfo.applicationInfo.packageName,
info.activityInfo.name),
Intent.FLAG_ACTIVITY_NEW_TASK
| Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED);
application.icon = info.activityInfo.loadIcon(manager);
mApplications.add(application);
}
}
This will help u to load all the apps downloaded.
