通过系统广播，获得apk的packageName以后，如何仅通过packageName获取其他信息

PackageManager pm = context.getPackageManager();

ApplicationInfo ai = pm.getApplicationInfo(packageName, 0);

String appName = pm.getApplicationLabel(ai).toString();

Drawable icon = pm.getApplicationIcon(packageName);

Drawable logo = pm.getApplicationLogo(packageName);
