PackageManager死亡-DeadObjectException-小包裹事务失败

public static boolean isAppInstalled(String packageName) {
    PackageManager pm = MainApp.get().getPackageManager();
    try {
        pm.getPackageInfo(packageName, PackageManager.GET_ACTIVITIES);
        return true;
    } catch (PackageManager.NameNotFoundException e) {
        return false;
    }
}

有时会在线路上撞车 getPackageInfo 具有以下stacktrace:

java.lang.RuntimeException: Package manager has died
    at android.app.ApplicationPackageManager.getPackageInfo(ApplicationPackageManager.java:151)
    ... code in my app => getPackageInfo line above ...
Caused by: android.os.DeadObjectException: Transaction failed on small parcel; remote process probably died

    at android.app.ApplicationPackageManager.getPackageInfo(ApplicationPackageManager.java:145)
    ...

你知道为什么会这样吗?我以为这样的事情只有在同时安装/卸载应用程序时才会发生,但我有一个用户可以重复这个过程,并且总是得到这个异常。
