Question

I wanted to ask,… What would be the most efficient way to detect the Google Voice Search (app id: com.google.android.voicesearch) installation on Android device?
And is there any way of subsequently installing it without taking user to Play Market and back to application?

You can use the below method

private boolean voiceSearchExists() {
    final Intent mainIntent = new Intent(Intent.ACTION_MAIN, null);
    mainIntent.addCategory(Intent.CATEGORY_LAUNCHER);
    List<PackageInfo> packs = getPackageManager().getInstalledPackages(0);
    final List<ResolveInfo> pkgAppsList = getPackageManager().queryIntentActivities( mainIntent, 0);
    boolean packageExists = false;
    boolean activityExists = false;
    for(PackageInfo r:packs){
        String pkg = r.applicationInfo.packageName;
        if(pkg != null && pkg.equals("com.google.android.googlequicksearchbox")){
            packageExists = true;
            break;
        }
    }
    if(packageExists == false)
        return false;

    for(ResolveInfo r:pkgAppsList){ 
        ActivityInfo info = r.activityInfo;
        if(info!=null && info.name!=null && info.name.equals("com.google.android.googlequicksearchbox.VoiceSearchActivity")){
            activityExists = true;
            break;
        }
    }
    return activityExists;
}
