Get application name android package name from all application which have launcher (Not all app in device)

app_listing.java

PackageManager pm = getPackageManager();
Intent main = new Intent(Intent.ACTION_MAIN, null);
main.addCategory(Intent.CATEGORY_LAUNCHER);
List<ResolveInfo> packages = pm.queryIntentActivities(main, 0);
		
ArrayList<String> app_name_list = new ArrayList<String>();
ArrayList<String> app_package_list = new ArrayList<String>();
		
for(ResolveInfo resolve_info : packages) {
    try {
        String package_name = resolve_info.activityInfo.packageName;
	String app_name = (String)pm.getApplicationLabel(
	        pm.getApplicationInfo(package_name
		, PackageManager.GET_META_DATA));
        boolean same = false;
	for(int i = 0 ; i < app_name_list.size() ; i++) {
	    if(package_name.equals(app_package_list.get(i)))
	    same = true;
	}
	if(!same) {
	    app_name_list.add(app_name);
	    app_package_list.add(package_name);
	}
	//Log.i("Check", "package = <" + package_name + "> name = <" + app_name + ">");
    } catch(Exception e) { }
}

Good practice!

add get versionName and get appIcon function

String versionName = pm.getPackageInfo(packageName, 0).versionName;
Drawable appIcon = pm.getApplicationIcon(packageName);
