清除数据并在android中卸载应用程序后如何清除计数标志？ [英] How to clear count badge after clearing data and uninstall application in android?

问题描述

问题是当我安装应用程序并使用它时，它在应用程序图标上显示计数标志。现在，当我卸载应用程序（当计数徽章显示在应用程序图标上）并重新安装该应用程序时，它再次在应用程序图标上显示徽章计数。

The problem is when I install application and use it, it shows count badge on application icon. Now when I un-install application (while count badge is being displayed on application icon), and re-install the application, it again shows badge count on application icon.

（注意：-这是在卸载应用程序时显示的最新徽章计数）

我的问题是：

1. 为什么重新安装应用程序后会显示徽章计数？

推荐答案

您链接的问题/答案实际上具有如何清除徽章的答案。

The question/answer you link actually has the answer on how to clear badges.

ContentValues cv = new ContentValues();
cv.put("badgecount", 0);
getContentResolver().update(Uri.parse("content://com.sec.badge/apps"), cv, "package=?", new String[] {getPackageName()});

因此，只需调用此方法即可清除徽章。

So just call this method appropriately to clear the badge.

例如，检查是否是从全新安装以来第一次加载应用，然后应用。

For example, check if first time loading app since fresh install, then apply.

  // CHECK IF FIRST LOAD
  if(!PreferenceManager.getDefaultSharedPreferences(this).contains("NOTFIRSTLOAD"))
 {
       ContentValues cv = new ContentValues();
       cv.put("badgecount", 0);
       getContentResolver().update(Uri.parse("content://com.sec.badge/apps"), cv, "package=?", new String[] {getPackageName()});  

       // Store that its not first load 
       PreferenceManager.getDefaultSharedPreferences(this).edit().putInt("NOTFIRSTLOAD", 1).commit();
  }
