本文详细阐述了如何通过编程实现启动特定应用的功能，包括检查应用是否存在、获取应用信息及启动应用的过程。

private void startOtherAPP(int index) {
    if(index <= ITEM_NUM_INVALID || index >= ITEM_NUM_MAX) return;
     String class_name;
    String package_name = app_list_packageName[index];
        if(app_list_className[index].startsWith("."))
    {
      class_name = package_name + app_list_className[index];
    }
    else
    {
      class_name = app_list_className[index];
    }

     if(index==1)
    {
      class_name = app_list_className[index];
    }
    if(checkApkExist(getApplicationContext(),package_name))
    {
      Intent intent = new Intent();
        ComponentName cn = new ComponentName(package_name,class_name);
        intent.setComponent(cn);
        intent.setAction("android.intent.action.VIEW");
        startActivity(intent);

    }
    else
    {
    Uri u = Uri.parse("market://details?id="+ package_name);
  Intent i = new Intent(Intent.ACTION_VIEW,u);
  startActivity(i);
    }

    }
      public boolean checkApkExist(Context context, String packageName) {
        if (packageName == null || "".equals(packageName))
                return false;
        try {
                ApplicationInfo info = context.getPackageManager()
                                .getApplicationInfo(packageName,
                                                PackageManager.GET_UNINSTALLED_PACKAGES);
                return true;
        } catch (NameNotFoundException e) {
                return false;
        }
      }
