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“包管理器已经死了”，由TransactionTooLargeException引发，答案是Binder事务的1MB限制。但是我还没有找到原因“包管理器已经死亡导致By DeadObjectException”，是PackageManagerServeice死了吗？如何解决这个问题？

当我使用“getPackageInfo”方法
