                jo.put("packageName", p.applicationInfo.packageName);

推荐答案

下面是一个片段说明你想做什么：

Here's a snippet illustrating what you want to do:


    public InstalledPackage(PackageManager pm, ApplicationInfo ai, Drawable defaultIcon) {
        name = ai.packageName;
        icon = defaultIcon;
        pkg = ai.packageName;
        if (ai.labelRes != 0) {
            name = (String) pm.getText(ai.packageName, ai.labelRes, ai);
        }
        if (ai.icon != 0) {
            icon = pm.getDrawable(ai.packageName, ai.icon, ai);
        }
    }

请记住很多的包不会有一个标签。

Keep in mind many packages won't have a label.
