首先通过adb查看含有fingerprint的属性值

lahaina:/ $ getprop | grep finger

 修改方法如下：

最后通过adb可以看到属性修改符合客户需求的了。

 

注意，高通的SDK是有两套android源码的。然后ro.build.fingerprint 在QCM6490_apps_qssi13/LINUX/android/system/core/init/property_service.cpp 下面有设置。代码如下，build.prop 中添加ro.build.fingerprint属性，init会根据上面的系统属性自动拼接

所以我直接在sysprop.mk里面添加了ro.product.brand 等属性。

 

// If the ro.build.fingerprint property has not been set, derive it from constituent pieces
static void property_derive_build_fingerprint() {
    std::string build_fingerprint = GetProperty("ro.build.fingerprint", "");
    if (!build_fingerprint.empty()) {
        return;
    }

    build_fingerprint = ConstructBuildFingerprint(false /* legacy fingerprint */);
    LOG(INFO) << "Setting property '" << FINGERPRINT_PROP << "' to '" << build_fingerprint << "'";

    std::string error;
    uint32_t res = PropertySet(FINGERPRINT_PROP, build_fingerprint, &error);
    if (res != PROP_SUCCESS) {
        LOG(ERROR) << "Error setting property '" << FINGERPRINT_PROP << "': err=" << res << " ("
                   << error << ")";
    }
}


static std::string ConstructBuildFingerprint(bool legacy) {
    const std::string UNKNOWN = "unknown";
    std::string build_fingerprint = GetProperty("ro.product.brand", UNKNOWN);
    build_fingerprint += '/';
    build_fingerprint += GetProperty("ro.product.name", UNKNOWN);
    build_fingerprint += '/';
    build_fingerprint += GetProperty("ro.product.device", UNKNOWN);
    build_fingerprint += ':';
    build_fingerprint += GetProperty("ro.build.version.release_or_codename", UNKNOWN);
    build_fingerprint += '/';

    std::string build_id =
            legacy ? GetProperty(LEGACY_ID_PROP, UNKNOWN) : GetProperty(ID_PROP, UNKNOWN);
    build_fingerprint += build_id;
    build_fingerprint += '/';
    build_fingerprint += GetProperty("ro.build.version.incremental", UNKNOWN);
    build_fingerprint += ':';
    build_fingerprint += GetProperty("ro.build.type", UNKNOWN);
    build_fingerprint += '/';
    build_fingerprint += GetProperty("ro.build.tags", UNKNOWN);

    return build_fingerprint;
}
