我没有对 Android Studio 生成的模板应用程序进行任何更改。

为什么不生成模板应用程序启动干净？

我尝试迁移到 androidX，但问题仍然完全相同。

为什么 Android Studio 不能生成一个“干净”的模板应用程序？

我的档案就像这样:-

buildscript {


repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.2.0'




// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}


allprojects {
repositories {
google()
jcenter()
}
}


task clean(type: Delete) {
delete rootProject.buildDir
}

====

apply plugin: 'com.android.application'


android {
compileSdkVersion 28
defaultConfig {
applicationId "com.manacle.secondmanacle"
minSdkVersion 21
targetSdkVersion 28
versionCode 1
versionName "1.0"
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}


dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'androidx.appcompat:appcompat:1.0.0'
implementation 'androidx.constraintlayout:constraintlayout:2.0.0-alpha2'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'androidx.test:runner:1.1.0-alpha4'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.0-alpha4'
}

最佳答案

有时在升级之后，您需要使缓存失效并清除缓存。

enter image description here

在3.2中有一些已知的问题，所以还要确保您不使用 Kotlin 工具 Kotlin: kotlin-gradle-plugin: 1.2.70

因为这也会导致冻结问题。 如果这不起作用，删除您的谷歌插件行和支持库，同步和添加他们再次和同步。有时候缓存目录会出错。

我在 build.gradle 文件的底部粘贴了这个文件，从而解决了一个类似的问题

configurations.all {
resolutionStrategy.eachDependency { DependencyResolveDetails details ->
def requested = details.requested
if (requested.group == "com.android.support") {
if (!requested.name.startsWith("multidex")) {
details.useVersion "26.+"
}
}
}
}

如果您正在使用 android x，请尝试这个(将此代码段添加到应用程序级别的 Gradle 文件中)

configurations.all {
resolutionStrategy.eachDependency { DependencyResolveDetails details ->
def requested = details.requested
if (requested.group == "androidx") {
if (!requested.name.startsWith("multidex")) {
details.useVersion "${targetSdk}.+"
}
}
}}

如果您不使用 android x，请尝试这段代码。

configurations.all {
resolutionStrategy.eachDependency { DependencyResolveDetails details ->
def requested = details.requested
if (requested.group == "com.android.support") {
if (!requested.name.startsWith("multidex")) {
details.useVersion "26.+"
}
}
}}

这个错误可能是个诱饵。在我的示例中，实际错误是堆栈跟踪中的某个 Resources$NotFoundException。当我用 ImageView代替 <androidx.appcompat.widget.AppCompatImageView时，我得到了一个可读的错误，这个错误很容易解决。

My problem was missing the androidx import in the build.gradle for one of the view elements in the layout that was being inflated. Adding implementation 'androidx.drawerlayout:drawerlayout:1.0.0 ' fixed my specific problem. I imagine there is some androidx view that is inside your Main Activity's layout that is not imported. All of the different packages and versions are at https://maven.google.com/web/index.html, simply find the item you are missing and add it to the dependencies in your module's build.gradle.

我挣扎在同样的例外，但只有当测试我的应用程序在一个真正的设备(三星 Galaxy S9)。同样的应用程序在虚拟设备上运行良好。 由于 build.gradle 配置更改没有得到解决，我通过将主要活动从 AppCompatActivity 移动到 Activity 来解决这个问题。我听起来像是降低你的活动级别，但是如果你没有使用高级活动特性-看这个(https://developer.android.com/reference/androidx/appcompat/app/AppCompatActivity)-这不是一个真正的问题。

//import androidx.appcompat.app.AppCompatActivity;
import android.app.Activity;


public class MainActivity /*extends AppCompatActivity*/ extends Activity

在 androidx 依赖性方面也有类似的问题

Rejecting re-init on previously-failed class java.lang.Class<androidx.core.view.ViewCompat$2>: java.lang.NoClassDefFoundError: Failed resolution of: Landroid/view/View$OnUnhandledKeyEventListener;

Resolved by adding configurations in Gradle files as below

configurations.all {
resolutionStrategy.eachDependency { DependencyResolveDetails details ->
def requested = details.requested
if (requested.group == "androidx.appcompat") {
if (!requested.name.startsWith("multidex")) {
details.useVersion "1.+"
}
}
}
}

我解决了一个类似的问题

Rejecting re-init on previously-failed class java.lang.Class<androidx.core.view.ViewCompat$2>: java.lang.NoClassDefFoundError: Failed resolution of: Landroid/view/View$OnUnhandledKeyEventListener;
 

Caused by: java.lang.ClassNotFoundException: Didn't find class "android.view.View$OnUnhandledKeyEventListener"

在 build.gradle (应用程序级别)中添加依赖项

implementation 'androidx.core:core:1.5.0-alpha04'
小开

Add this to gradle will resolve the issue, works for me:

implementation 'androidx.appcompat:appcompat:1.3.0-alpha02'

请注意1.2.0甚至不工作

小开

对我有用，谢谢 Amos 在最上面

将此添加到 Gradl 中的依赖项中

    implementation 'androidx.core:core:1.5.0-alpha04'
