How to parse a zipped file completely from RAM?

QUESTION

How to parse a zipped file completely from RAM?

Asked 2020-May-16 at 16:53

Background

I need to parse some zip files of various types (getting some inner files content for one purpose or another, including getting their names).

Some of the files are not reachable via file-path, as Android has Uri to reach them, and as sometimes the zip file is inside another zip file. With the push to use SAF, it's even less possible to use file-path in some cases.

For this, we have 2 main ways to handle: ZipFile class and ZipInputStream class.

The problem

When we have a file-path, ZipFile is a perfect solution. It's also very efficient in terms of speed.

However, for the rest of the cases, ZipInputStream could reach issues, such as this one, which has a problematic zip file, and cause this exception:

You can steal LWJGL's native memory management functions. It is BSD3 licensed, so you only have to mention somewhere that you are using code from it.

Step 1: given an InputStream is and a file size ZIP_SIZE, slurp the stream into a direct byte buffer created by LWJGL's org.lwjgl.system.MemoryUtil helper class:

Android Studio | CPP file errors error: undefined reference to 'AndroidBitmap_unlockPixels' In bitmap library

Asked 2020-May-15 at 10:00

I'm trying to use AndroidJniBitmapOperations library. But I'm a Junior Dev, with no knowledge in the NDK, JNI world.

I succeed to resolve a few errors like 'UnsatisfiedLinkError', but Now I'm getting a new one when I trying to build:

error: undefined reference to 'AndroidBitmap_unlockPixels'

Also I get a few errors inside the CPP file:

1."Incorrect type for parameter 'prarmeterName', which should have type 'jint'.

2."Add extern 'C'"

But I don't sure if the last 2 are important.

Help me to update this library, because its important and talked in SO several times, like: here.

The link for the library it self: https://github.com/AndroidDeveloperLB/AndroidJniBitmapOperations

You need to link the library that provides that API. In https://github.com/LiorA1/MyRevApp/blob/master/app/src/main/cpp/CMakeLists.txt, copy the code that you have for the logging library like so:
