当我使用“getPackageInfo”方法时，包管理器因 DeadObjectException 而死亡

Question

例外

我的代码

    public int isSystemApp(String packageName) {
    int systemApp = 1;
    int notSystemApp = 2;
    int unKnown = 3;
    if (TextUtils.isEmpty(packageName)) {
        return unKnown;
    }
    if (mContext == null) {
        return unKnown;
    }
    try {
        PackageManager packageManager = mContext.getPackageManager();
        if (packageManager != null && packageName != null) {
            PackageInfo packageInfo = packageManager.getPackageInfo(packageName, 0);
            if (packageInfo != null && packageInfo.applicationInfo != null && ((packageInfo.applicationInfo.flags & ApplicationInfo.FLAG_SYSTEM) != 0)) {
                return systemApp;
            } else {
                return notSystemApp;
            }
        }
    } catch (PackageManager.NameNotFoundException e) {
        e.printStackTrace();
    }
    return unKnown;
}

我发现了一些其他问题“包管理器已死”，由 TransactionTooLargeException 引起，答案是 Binder 事务的 1MB 限制。如何解决这个问题呢？
