    To launch other application from your app, you need to have it’s package name and you can start other app thru;

    ResolveInfo info;
packageName = info.activityInfo.applicationInfo.packageName;

Intent mIntent = getPackageManager().getLaunchIntentForPackage(packageName);
        mIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        mIntent.addFlags(Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED);
        if (null != mIntent) {
            try {
                startActivity(mIntent);
            } catch(Exception e) {      }
        }

    you can get installed package thru:

    ArrayList<PackageInfo> res = new ArrayList<PackageInfo>();
        PackageManager pm = context.getApplicationContext().getPackageManager();
        List<PackageInfo> packs = pm.getInstalledPackages(0);
