image_picker 在构建中抛出的异常

Question

我现在两天都在与 image_picker 搏斗。当我试图调试我的应用程序时，它从昨天中午开始。之前它会调试得很好，据我所知，在那段时间我没有改变任何东西。它unexpected element <queries> found in <manifest>.抛出错误，就像今天下面的错误日志一样，它启动了Jetfier来解决不兼容问题。Jetfier 昨天抛出的错误类似于SDK location not found. Define location in local.properties or with an ANDROID_SDK_ROOT environment variable. 但是 SDK 位置是在 local.properties 中定义的，我还创建了ANDROID_SDK_ROOTenv。SDK 位置的变量，但错误保持不变。

今天我彻底清除了flutter文件夹并重新安装了它。在那之后，我在设备信息方面遇到了一些问题，但最终得到了解决。现在我被困在这里，我没有任何进展。如果我删除<queries>in AndroidManifest.xml，它会在尝试运行程序时再次放在那里，所以这不是解决方案。

我把它pubspec.yaml作为file_picker: ^2.0.10下依赖和我试过pub get，pub cache repair，pub clean在不同的订单。如果我删除项目中的file_picker和所有它的用途，应用程序的其余部分运行得很好。我file_picker在另一个项目中尝试了一些更基本的东西，它也在那里抛出了同样的异常。

下面是错误代码。如果您需要更多详细信息，请告诉我。

The built failed likely due to AndroidX incompatibilities in a plugin. The tool is about to try using Jetfier to solve the incompatibility.

Answer 1

对于那些不知道的人（包括我自己）有两个build.gradle文件

1. android/build.gradle
2. android/app/build.gradle

步骤 1 里面 android/build.gradle

buildscript {
    ext.kotlin_version = '1.3.50'
    repositories {
        google()
        jcenter()
    }

    dependencies {
        // classpath 'com.android.tools.build:gradle:3.5.0' before
        classpath 'com.android.tools.build:gradle:4.0.1' // after
    }
}

里面的第2步 android/gradle/wrapper/gradle-wrapper.properties

distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists

# BEFORE
# distributionUrl=https\://services.gradle.org/distributions/gradle-5.6.2-all.zip
# AFTER
distributionUrl=https://services.gradle.org/distributions/gradle-6.1.1-all.zip

第 3 步重建项目

可能需要一段时间，因为它会下载新的 gradle

Answer 2

这是因为在 Android 11 及更高版本 (SDK 30+) 中引入了新的包可见性选项。因此，您需要使用包含此更改的版本更新 build.gradle。以下是支持的 gradle 选项列表。

'3.3.3'、'3.4.3'、'3.5.4'、'3.6.4'、'4.0.1'

不要忘记更新 gradle-wrapper.properties 中的 ditributionUrl。例如，对于 gradle 4.0.1，你应该有：

distributionUrl=https://services.gradle.org/distributions/gradle-6.1.1-all.zip

参考： https : //github.com/miguelpruivo/flutter_file_picker/wiki/Troubleshooting#android

Answer 3

** 最新更新 **

android/build.gradle 中的步骤 1

buildscript {
ext.kotlin_version = '1.3.50'
repositories {
    google()
    jcenter()
}

dependencies {
    // change to build:gradle:3.6.3
    classpath 'com.android.tools.build:gradle:3.6.3'
    classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    classpath 'com.google.gms:google-services:4.3.3'
}

}

android/gradle/wrapper/gradle-wrapper.properties 中的步骤 2

distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
// change distributionUrl to gradle-6.5-all.zip
distributionUrl=https\://services.gradle.org/distributions/gradle-6.5-all.zip
