Question

我使用android studio创建了简单的hello world应用程序。它在Lollipop和Marshmallow上运行但在Kitkat没有。我将targetSDKversion更改为19后尝试运行应用程序。但是，它也没有运行。消息就像是一样 ＆＃34;遗憾的是应用停止了＃34; 。这是我的build.gradle文件：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.2"

    defaultConfig {
        applicationId "com.example.vivek.myhelloworldapp"
        minSdkVersion 14
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:24.0.0-alpha1'
}

这是我在kitkat设备上进行USB调试时遇到的错误

我希望有人能帮助我摆脱这个问题。

Android应用程序不适用于Kitkat版本，但适用于Lollipop和Marshmallow
