我想反编译一个现有的Android应用程序，修改后重新编译并签名，但我无法在Android 11上安装.我在Emulator上收到了这样的错误消息:
错误代码:'—124'，消息='—124:在安装过程中解析失败PackageLI:目标R+(版本30及以上)需要将已安装APK的资源. arsc存储为未压缩的并在4字节边界上对齐'
我使用的方法:
Manual Process:
Step 1: Generate Keystore (only once)
You need to generate a keystore once and use it to sign your unsigned apk. Use the keytool provided by the JDK found in %JAVA_HOME%/bin/
keytool -genkey -v -keystore my.keystore -keyalg RSA -keysize 2048 -validity 10000 -alias app
Step 2 or 4: Zipalign
zipalign which is a tool provided by the Android SDK found in e.g. %ANDROID_HOME%/sdk/build-tools/24.0.2/ is a mandatory optimization step if you want to upload the apk to the Play Store.
zipalign -p 4 my.apk my-aligned.apk
Note: when using the old jarsigner you need to zipalign AFTER signing. When using the new apksigner method you do it BEFORE signing (confusing, I know). Invoking zipalign before apksigner works fine because apksigner preserves APK alignment and compression (unlike jarsigner).
You can verify the alignment with
zipalign -c 4 my-aligned.apk
Step 3: Sign & Verify
Using build-tools 24.0.3 and newer
Android 7.0 introduces APK Signature Scheme v2, a new app-signing scheme that offers faster app install times and more protection against unauthorized alterations to APK files (See here and here for more details). Therefore, Google implemented their own apk signer called apksigner (duh!) The script file can be found in %ANDROID_HOME%/sdk/build-tools/24.0.3/ (the .jar is in the /lib subfolder). Use it like this
apksigner sign --ks-key-alias alias_name --ks my.keystore my-app.apk
and can be verified with
apksigner verify my-app.apk
The official documentation can be found here.
Using build-tools 24.0.2 and older
Use jarsigner which, like the keytool, comes with the JDK distribution found in %JAVA_HOME%/bin/ and use it like so:
jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore my.keystore my-app.apk my_alias_name
and can be verified with
jarsigner -verify -verbose my_application.apk
我应该用什么工具来解决这个问题呢？当我读到这篇由Android 11引起的文章时.
