我正在尝试使用 cordova build android 命令构建 APK，但在构建期间发生错误并且无法生成构建。错误与 PICASSO 库有关。请在下面找到所有相关详细信息。 ionic 信息:

 Ionic:
 ionic (Ionic CLI) : 4.8.0 (/usr/lib/node_modules/ionic)
 Ionic Framework   : ionic1 1.3.1
 @ionic/v1-toolkit : not installed
 Cordova:
 cordova (Cordova CLI) : 8.1.2 (cordova-lib@8.1.1)
 Cordova Platforms     : android 6.4.0
 Cordova Plugins       : cordova-plugin-ionic-webview 1.2.1, (and 19 
 other plugins)

 System:

 Android SDK Tools : 26.1.1 (/home/user/Android/Sdk)
 NodeJS            : v8.11.3 (/usr/bin/node)
 npm               : 5.6.0
 OS                : Linux 4.15

platforms/android/com-sarriaroman-photoviewer/abc123photoviewer.gradle 有以下代码

repositories{
jcenter()
}
dependencies {
implementaion 'com.commit451:PhotoView:1.2.4'
implementaion 'com.squareup.picasso:picasso:2.5.2'
}
android {

}

因此错误

最佳答案

这是插件 1.20 版的问题。

您可以使用 1.1.18，它与它配合得很好。

这里是如何移动到 1.1.18

$ ionic cordova plugin rm com-sarriaroman-photoviewer
$ ionic cordova plugin add com-sarriaroman-photoviewer@1.1.18

构建并运行

cordova build android 

...
...
...
:app:transformResourcesWithMergeJavaResForDebug
:app:packageDebug
:app:assembleDebug
:app:cdvBuildDebug

如果这仍然给您带来与之前相同的错误，请尝试删除一次 android 平台并再次添加，

$ cordova platform rm android

$ cordova platform add android

关于android - 由于找不到符号 picasso.fit()，无法构建 apk；，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/54341974/
