我目前正在使用Android Studio开发Android应用程序，在我的Windows机器上工作了很长时间之后，我正在尝试在MacBook Air上运行它。
我复制了项目文件并在Mac上创建了一个模拟器（API 25）。该项目编译得很好，但由于以下错误，它会立即在仿真器上崩溃：

我（希望）目前已经实现了Android支持库（v7），您可以在我的build.gradle中看到：
apply plugin: 'com.android.application'
android {
compileSdkVersion 25
buildToolsVersion "25.0.3"
defaultConfig {
applicationId "com.lennartschoch.partytime"
minSdkVersion 19
targetSdkVersion 25
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:design:25.3.1'
compile 'com.android.support.constraint:constraint-layout:1.0.2'
compile 'com.android.support:support-v4:25.3.1'
compile 'com.android.support:recyclerview-v7:25.3.1'
compile 'com.android.support:cardview-v7:25.3.1'
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:25.3.1'
}
我已经尝试过清理和重建项目，但我无法摆脱这个问题。有什么建议吗？
谢谢！

将Android项目移动到旧目录的子目录后，我遇到了同样的问题。首先，当我尝试在早期的同一设备上运行项目时，我收到以下错误：
DELETE_FAILED_INTERNAL_ERROR
Error while Installing APKs
我通过执行Build -> Clean Project摆脱了这一点，但后来我得到了这些ClassNotFound例外，应用程序立即崩溃了。这是通过在项目根目录中的终端中运行gradlew clean并再次构建来解决的。
