包名称 - 应用包的名称.

名称 - 与应用程序关联的文本标签.您不能只使用 appInfo.name，因为它会返回 null.使用 appInfo.loadLabel(packageManager) 您会得到实际应用的名称，例如 Speech Recorder，而不是包名称 com.android.speechrecorder.

Name - text label associated with the application. You can't use just appInfo.name as it will return null. Using appInfo.loadLabel(packageManager) you get the actual app's name like Speech Recorder instead of package name com.android.speechrecorder.

final PackageManager packageManager = getPackageManager();
List<ApplicationInfo> installedApplications = 
   packageManager.getInstalledApplications(PackageManager.GET_META_DATA);

for (ApplicationInfo appInfo : installedApplications)
{
    Log.d("OUTPUT", "Package name : " + appInfo.packageName);
    Log.d("OUTPUT", "Name: " + appInfo.loadLabel(packageManager));
}
