comparing two apk files to check the difference between then(size difference of 1 kb)

Question

I have two apks, which basically are exactly the same but their size differs by 1 KB. I would like to check what this difference is. Is there any tool available for this purpose?

When i unzip the apk's , the size turns out to be exactly the same.

Answer 1

这就是你要找的apkanalyzer

Answer 2

APK 文件本质上是一个存档，因此尝试在您感兴趣的 apk 上运行zipcmp命令。它显示存档中不同文件的大小和哈希值。

Answer 3

Here is how to compare the content of apks.

1. Unzip apks and compare META-INF/MANIFEST.MF files - it will show which file differs. If none, the zip structure differs (not suremaybe zip headers?).

2. apktool decode both apks to folders - it will result in files with decoded resources, manifest and classes to folders.

3. directory compare (ie meld ) bot folders to investigate the difference in file content.
