优化后使用apkzlib读取apk文件报错，请问有什么办法可以兼容吗

Cannot read entry '**/test.apk' (offset: 6460432, size: 137274417) because it overlaps with 'lib/arm64-v8a/libALBiometricsJni.so'

某些原始apk so文件数据复用优化后会无法安装

两个 && 应该改成 ||

这样改也可以：

                // 必须4k对齐
                if (innerEntry.getMethod() == ZipMaker.METHOD_STORED || innerEntry.getDataOffset() % 4 != 0) {
                    String name = innerEntry.getName();
                    if (name.equals("resources.arsc") || name.endsWith(".so")) {
                        System.out.println(name + " getDataOffset: " + (innerEntry.getDataOffset() % 4));
                        System.out.println(name + " getMethod: " + (innerEntry.getMethod() == ZipMaker.METHOD_STORED));
                        continue;
                    }
                }

输出：

lib/armeabi/libxxx.so getDataOffset: 0
lib/armeabi/libxxx.so getMethod: true

经过打印 innerEntry.getDataOffset() % 4 发现是启用了 4k 对齐，但是 innerEntry.getMethod() 是 METHOD_STORED 。这样改就正常了。

进行复用优化后，APK无法安装

进行复用优化后，APK内文件压缩后大小都变成了0kb，导致APK无法被安装


安装报错：

Failure [INSTALL_FAILED_INVALID_APK: INSTALL_FAILED_INVALID_APK: Failed to extract native libraries, res=-2]

对大apk进行数据复用会有问题

使用V1 + V2 / V3 签名的apk进行数据数据复用：

1、测试在800多MB的apk是正常的

2、测试在2.2G的apk（com.studiowildcard.wardrumstudios.ark），安装会报错
Failure [INSTALL_PARSE_FAILED_NO_CERTIFICATES: Failed to collect certificates from /data/app/vmdl1215474834.tmp/base.apk using APK Signature Scheme v3: integer overflow]
而只使用apksig 进行 V1 + V2 / V3 签名，没有数据复用，可以正常安装，能否提供点帮助，非常感谢

弱弱问下，这行代码是不是写错了

if (name.equals("resources.arsc") || name.startsWith(".so")) {
是不是应该为
if (name.equals("resources.arsc") || name.endsWith(".so")) {

Storage APK does not work

I made a simple command line tool on PC for this. I repackaged original APK as storage, assuming it means no compression but I'm still getting error that it must be packaged with the stored method, regardless what zip utilities. What I am doing wrong?

Exception in thread "main" java.io.IOException: Entry must be packaged with the stored method: assets/test.apk
	at bin.zip.DataMultiplexing.openEntryAsZipFile(DataMultiplexing.java:156)
	at bin.zip.DataMultiplexing.collectChildren(DataMultiplexing.java:113)
	at bin.zip.DataMultiplexing.optimize(DataMultiplexing.java:44)
	at bin.zip.DataMultiplexing.optimize(DataMultiplexing.java:30)
