如何为使用flutter构建的多个架构apk分配不同的versionCode

Question

我的

pubspec.yaml

的版本代码为11。

使用

flutter build apk

构建胖 apk 会按预期提供

versionCode

11 的 apk。但是构建一个

armeabi-v7a-release

apk 会得到一个

versionCode

1011 而不是 11 的 apk。

我想将armeabi-v7a的versionCode递增1000的行为更改为android的文档中提到的（感谢@Varun Kumar指出它）。我希望

armeabi-v7a

apk 的版本代码与

pubspec.yaml

中提到的版本代码相对应。如何编辑 this build.gradle 来实现相同的效果？

Answer 1

发现可以通过向

versionCode

添加代码来覆盖输出 .apk 文件的

build.gradle(:app)

，如 android 文档中所述，这允许我们显式修改为每个 abi 分配

versionCode

所遵循的逻辑。

为了避免单独对armeabi-v7a进行1000增量，我将内部if块的逻辑修改为以下内容：

        if (baseAbiVersionCode != null ) {
            output.versionCodeOverride =
                    baseAbiVersionCode * 1000 + variant.versionCode

            if (baseAbiVersionCode == 1) { // Matches armeabi-v7a in ext.abiCodes
                // Uses the default versionCode for armeabi-v7a APKs.
                output.versionCodeOverride = variant.versionCode
            }
        }

注意：这部分有点hacky，因为您最终可能会为 fat apk 和armeabi-v7a ABI 提供相同的

versionCode

。我建议仅当您只想专门针对一个 ABI 时才使用此选项。

根据android文档 像这样更改 app/build.gradle :

android {
    ...
}
...
// -- > add these lines :
// For each APK output variant, override versionCode with a combination of
// ext.abiCodes * 1000 + variant.versionCode. In this example, variant.versionCode
// is equal to defaultConfig.versionCode. If you configure product flavors that
// define their own versionCode, variant.versionCode uses that value instead.
android.applicationVariants.all { variant ->

    // Assigns a different version code for each output APK
    // other than the universal APK.
    variant.outputs.each { output ->

        // Stores the value of ext.abiCodes that is associated with the ABI for this variant.
        def baseAbiVersionCode =
                // Determines the ABI for this variant and returns the mapped value.
                project.ext.abiCodes.get(output.getFilter(com.android.build.OutputFile.ABI))

        // Because abiCodes.get() returns null for ABIs that are not mapped by ext.abiCodes,
        // the following code doesn't override the version code for universal APKs.
        // However, because you want universal APKs to have the lowest version code,
        // this outcome is desirable.
        if (baseAbiVersionCode != null) {

            // Assigns the new version code to versionCodeOverride, which changes the
            // version code for only the output APK, not for the variant itself. Skipping
            // this step causes Gradle to use the value of variant.versionCode for the APK.
            output.versionCodeOverride = variant.versionCode
        }
    }
}
...
flutter {
    ...
}

我改变了：

if (baseAbiVersionCode != null) {

  // Assigns the new version code to versionCodeOverride, which changes the
  // version code for only the output APK, not for the variant itself. Skipping
  // this step causes Gradle to use the value of variant.versionCode for the APK.
  output.versionCodeOverride =
          baseAbiVersionCode * 1000 + variant.versionCode
}

至：

if (baseAbiVersionCode != null) {

  // Assigns the new version code to versionCodeOverride, which changes the
  // version code for only the output APK, not for the variant itself. Skipping
  // this step causes Gradle to use the value of variant.versionCode for the APK.
  output.versionCodeOverride = variant.versionCode
}
