android - Android 构建中的 libnativehelper 缺少变体

Question

我正在尝试在 Android 产品分区中编译 JNI。为此，我添加了属性 product_specific: true在 Android.bp 如:

cc_library_shared {
    name : "..."
    ...
       shared_libs: [
            "libandroidicu",
            "libnativehelper",
            "libcutils",
            "libutils",
            "liblog",
        ],
    proprietary : false;
    product_specific: true

不幸的是，在编译时出现以下错误:

Android.bp:1:1: dependency "libnativehelper" of "libTest_jni" missing variant:
  os:android, image:product.30, arch:arm64_armv8-a, sdk:, link:shared, version:1

available variants:
  os:android, image:, arch:arm64_armv8-a, sdk:, link:shared, version:
  os:android, image:, arch:arm64_armv8-a, sdk:, link:shared, version:1
  os:android, image:, arch:arm64_armv8-a, sdk:, link:static, version:
  os:android, image:, arch:arm64_armv8-a, sdk:, link:static, version:1
  os:android, image:, arch:arm_armv8-a, sdk:, link:shared, version:
  os:android, image:, arch:arm_armv8-a, sdk:, link:shared, version:1
  os:android, image:, arch:arm_armv8-a, sdk:, link:static, version:
  os:android, image:, arch:arm_armv8-a, sdk:, link:static, version:1

如何将产品变体添加到 libnativehelper？

Answer 1

libnativehelper 是非 SDK 接口(interface)的一部分。所以我们不能在产品分区中使用它。如果您进行逆向工程，系统将给出使用非 sdk 接口(interface)的确切库...
