我没有对Android Studio生成的模板应用程序进行任何更改。

为什么生成模板应用程序无法正常启动？

我尝试了迁移到androidX，但是问题仍然完全相同。

为什么Android Studio无法生成“干净的”模板应用程序？

我的gradle文件类似于：-

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'
}

Answer 1

有时，升级后，您需要使缓存无效并清除缓存。

3.2中存在一些已知问题，因此请确保您还没有使用Kotlin工具 org.jetbrains.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，请删除您的Google插件行和支持库，进行同步，然后再次添加它们并进行同步。有时，缓存目录会变得不正常。

Answer 2

遇到了类似androidx依赖的问题

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;

通过在Gradle文件中添加如下配置来解决

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

Answer 3

我解决了类似的问题

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'

Answer 4

此错误可能是诱饵。在我的情况下，实际错误证明是堆栈跟踪中某处的Resources$NotFoundException。当我将<androidx.appcompat.widget.AppCompatImageView替换为ImageView时，出现了一个易于阅读的错误，易于解决。

Answer 5

我的问题是在build.gradle中缺少被夸大的布局中的视图元素之一的androidx导入。添加implementation 'androidx.drawerlayout:drawerlayout:1.0.0 '解决了我的特定问题。我想您的主要活动的布局中有一些androidx视图没有导入。所有不同的软件包和版本都位于https://maven.google.com/web/index.html，只需找到您缺少的项目并将其添加到模块的build.gradle中的依赖项中即可。

Answer 6

如果您使用的是android x，请尝试将此操作（将此代码段添加到应用级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，请尝试以下代码段。

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

Answer 7

我为同样的异常而苦苦挣扎，但只有在真实设备（三星Galaxy S9）上测试我的应用程序时才这样做。同一应用程序在虚拟设备上运行良好。 由于build.gradle配置更改未解决，因此通过将主要活动从AppCompatActivity移至Activity来解决此问题。我听起来好像在降低您的活动等级，但是如果您不使用高级活动功能-请参阅（https://developer.android.com/reference/androidx/appcompat/app/AppCompatActivity）-这不是真正的问题。

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

public class MainActivity /*extends AppCompatActivity*/ extends Activity

Answer 8

将此内容添加到gradle将解决此问题，对我有用：

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

请注意1.2.0甚至不起作用

Answer 9

我通过将其粘贴到build.gradle文件的底部来解决了类似的问题

drives_a = [chr(x) + ':' for x in range(65, 90) if os.path.exists(chr(x) + ':')]

Answer 10

为我工作，感谢顶部的阿莫斯

将此添加到 Gradl 的依赖项中

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