推荐答案

• 运行 apksigner验证-v< apk> ，并在输出中查找使用v2方案(APK签名方案v2):true 验证的.apksigner可以在Android SDK构建工具24.0.3中找到.apksigner的源代码在这里: https://android.googlesource.com/platform/tools/apksig/.

  • Run apksigner verify -v <apk> and look for Verified using v2 scheme (APK Signature Scheme v2): true in the output. apksigner can be found in Android SDK build tools 24.0.3. apksigner's source code is here: https://android.googlesource.com/platform/tools/apksig/.

    对于Android Nougat上已安装的软件包: adb shell pm dump< package name>|grep apkSigningVersion . 1 表示常规的JAR签名方案， 2 表示APK签名方案v2.

    For an already installed package on Android Nougat: adb shell pm dump <package name> | grep apkSigningVersion. 1 means conventional JAR signing scheme, 2 means APK Signature Scheme v2.

    您还可以运行 grep'APK Sig Block 42'app.apk ，但这可能会有误报.只有在没有匹配项的情况下，才能确定未使用APK签名方案v2对APK进行签名.

    You can also run grep 'APK Sig Block 42' app.apk but this may have false positives. Only if there is no match is it certain that the APK is not signed using APK Signature Scheme v2.
