SO在成为iOS开发人员8年半之后,我在4个月前开始学习andorid,并获得了Cordova andorid项目进行研究。任务是集成指纹和面部ID登录。
我当前项目(非常旧的项目)中的内容:
构建gradle:2.3.3 gradle版本:3.3 cordova-android版本:5.1.4
我知道这些都很老。
最近10天来我一直在尝试什么:
我试图将以上版本升级到最新的build gradle和gradle版本。一堆又一堆的错误出现了。
我尝试在build.gradle和build-extra.gradle中一个接一个地添加生物识别支持库..但是没有任何效果...
我的问题:
为什么我不能添加生物识别支持库,当我在编译gradle 2.3.3和gradle 3.3时一切都可以编译并正常工作时?
我是否必须将gradle和每个支持库版本更新为最新版本?如果是,那么它将导致代码问题吗?可以说我曾经使用过任何旧的UI组件,当我尝试将旧的支持库与新的生物统计API合并时,它将生成编译时错误。我尝试过这个。
谁能告诉我逐步升级该项目的步骤,以便即使存在编译时错误,我也可以将其删除,然后,在一切正常的情况下,我可以添加生物识别支持库。
最近,生物识别技术支持库可以集成到任何旧项目中,这就是为什么它们被称为支持库。如果我错了请纠正我。

是的,它是一个混合应用程序。使用Cordova-android。
我已经尝试过像任何东西一样在Google上进行搜索,但是找不到使用最新生物识别支持库的简单演示Android(Cordova android)项目。
好的,所以上面的链接是一个可以正常运行的演示android应用。
只有一个问题困扰我:为什么我不能在build.gradle中添加此行(或者我需要在何处添加此行),或者如何添加它以便我在AS中的当前项目开始使用用于面部识别码登录的生物识别API。 依赖项{ 实现'androidx.biometric:biometric:1.0.0-alpha03'
注意:赏金将颁发给将逐步提供解决方案的人,该解决方案如何将我的生物识别支持API集成到我的当前项目中,该项目使用build-extra.gradle文件中所示的旧支持库。
答案 0 :(得分:1)
因此,经过14天的努力,终于使我3岁的代码正常工作了。
如果有人在寻找相同的东西,这里是详细的步骤。
所以我有一个Cordova android混合应用旧代码。使用Android Studio 3.2。构建gradle版本非常旧,为2.8,而gradle版本为3.3。
我首先将Android Studio升级到最新版本3.3.2
现在,我决定将整个项目迁移到androidX。记住,它甚至不会让我使用以前版本的Android Studio来做到这一点,我不知道为什么。
当我单击Refactor-> Migrate to AndroidX时。出现一个弹出窗口,提示“升级gradle版本。因此,现在我将gradle版本更新为4.10.1,如果将其升级到5.2,它仍然给我错误(我不知道为什么,我仍然是Android的新手。)建立gradle到3.3.2
5。我的build.gradle(模块:应用程序)如下所示:
apply plugin: 'com.android.application'
buildscript {
repositories {
jcenter{ url "http://jcenter.bintray.com/" }
google()
}
// Switch the Android Gradle plugin version requirement depending on the
// installed version of Gradle. This dependency is documented at
// http://tools.android.com/tech-docs/new-build-system/version-compatibility
// and https://issues.apache.org/jira/browse/CB-8143
dependencies {
classpath 'com.android.tools.build:gradle:3.3.2'
classpath "com.google.gms:google-services:3.0.0" //FCM Config
}
}
现在,App可以正常同步,构建正常。我再次尝试了Refactor-> Migrate to androidX。这次Android Studio开始重构代码,并向我提供了70条代码更改建议。
这些代码更改主要是头文件更改,例如:import“”。因此,我打开了此链接-https://developer.android.com/jetpack/androidx/migrate,并将每个导入语句更改为相等的androidx语句。
在复制粘贴所有更改之后,我再次编译并同步了代码。经过3个资源和代码编译错误,我能够构建代码。整个过程耗时1.2个小时。
最后,我能够将生物识别支持API导入build-extras.gradle(模块:app)中,查看文件:
dependencies {
api 'androidx.appcompat:appcompat:1.0.2'
api "com.squareup.picasso:picasso:2.4.0"
api "com.google.android.material:material:1.1.0-alpha04"
api "com.google.firebase:firebase-messaging:9.2.0" //FCM Config
api 'com.rmtheis:tess-two:6.0.2'
api 'com.github.bumptech.glide:glide:3.8.0'
api 'androidx.legacy:legacy-support-v4:1.0.0'
api "androidx.biometric:biometric:1.0.0-alpha03"
}
}
最后,我能够构建完整的代码并对其进行同步。很高兴终于做到了。现在,我只需要使用生物特征API函数将其集成到我的代码中(请注意,此代码是3年前编写的,并已提供给我用于集成最新的生物特征API)。
是的,我需要逐步回答这样的问题。
仍然感谢所有帮助过的人。

您需要在根项目的invalid literal for int() with base 10: '+'
中定义存储库:
build.gradle
这些版本是a)完全过时且b)请勿将allprojects {
repositories {
google()
}
}
与com.android.support
混合使用。并且您不能将Java依赖项添加到androidx
依赖项中,因为这会产生错误消息buildscript
。
,也许是本网站的read the manual,以便提供程序员期望的输入。仅仅是因为您拥有Mac,并不会将您排除在这些指导之外……确实存在是有原因的。
请勿张贴代码,数据,错误消息等的图像。-将文本复制或键入问题中。请保留将图片用于图表或演示渲染错误,这些错误无法通过文本准确描述。
我也可以简单地修复依赖关系...但是我太懒了,无法从屏幕截图中键入内容。
