Question

我的android studio突然停止构建之前运行良好的应用，但现在我什至无法运行基本的空应用。

同步并且一切正常，没有错误，但仅在我侧载（运行）应用程序或生成签名的APK时显示错误

已经尝试过

使缓存无效/重新启动
重新启动
更改Java版本
清理所有文件

什么都没做

build.gradle（app）

apply plugin: 'com.android.application'

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "in.alpha.test"
        minSdkVersion 21
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:28.0.0'
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
    implementation 'com.android.support:support-v4:28.0.0'
    implementation 'com.android.support:design:28.0.0'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
    implementation 'com.google.android.gms:play-services-vision:16.2.0'
    implementation 'com.google.android.gms:play-services-ads:18.0.0'
    implementation "com.android.support:support-core-utils:28.0.0"
}

build.gradel：

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {

    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.4.1'


        // 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
}

您的问题在于这段代码：

    dependencies {
        implementation fileTree(dir: 'libs', include: ['*.jar'])
        implementation 'com.android.support:appcompat-v7:28.0.0'
        implementation 'com.android.support.constraint:constraint-layout:1.1.3'
        implementation 'com.android.support:support-v4:28.0.0'
        implementation 'com.android.support:design:28.0.0'
        testImplementation 'junit:junit:4.12'
        androidTestImplementation 'com.android.support.test:runner:1.0.2'
        androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
        implementation 'com.google.android.gms:play-services-vision:16.2.0'
        implementation 'com.google.android.gms:play-services-ads:18.0.0'
        implementation "com.android.support:support-core-utils:28.0.0"
    }

基于此，您还没有fully migrated to AndroidX。

如果您要查找具有正确依赖项的复制/粘贴，请用以下内容替换依赖项块：

    dependencies {
        implementation fileTree(dir: 'libs', include: ['*.jar'])
        implementation 'androidx.appcompat:appcompat:1.0.2'
        implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
        implementation 'androidx.legacy:legacy-support-v4:1.0.0'
        implementation 'com.google.android.material:material:1.1.0-alpha07'
        testImplementation 'junit:junit:4.12'
        androidTestImplementation 'androidx.test:runner:1.2.0'
        androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
        implementation 'com.google.android.gms:play-services-vision:18.0.0'
        implementation 'com.google.android.gms:play-services-ads:18.0.0'
        implementation 'androidx.legacy:legacy-support-core-utils:1.0.0'
    }

还可以在defaultConfig块中更改testInstrumentationRunner。然后将compileSdkVersion和targetSdkVersion从28更改为29。

旧

    compileSdkVersion 28
    defaultConfig {
        applicationId "in.alpha.test"
        minSdkVersion 21
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }

新

    compileSdkVersion 29
    defaultConfig {
        applicationId "in.alpha.test"
        minSdkVersion 21
        targetSdkVersion 29
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }

Android Studio无法突然构建任何应用
