Question

我是Android开发的新手。我在android中开发了一个应用程序并设置了我的minSdkVersion 16和targetSdkVersion 16，但它仍然没有在软糖上运行，但在棉花糖上工作正常。

我无法找到错误。

我的gradle文件是：

apply plugin: 'com.android.application'

android {
compileSdkVersion 23
buildToolsVersion "24.0.3"
defaultConfig {
    applicationId "com.theakshaynaik.pocketambulance"
    minSdkVersion 16
    targetSdkVersion 16
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    multiDexEnabled true
}
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 files('libs/httpclient-4.0.3.jar')
compile 'com.android.support:appcompat-v7:23.4.0'
compile 'com.firebaseui:firebase-ui:0.5.1'
compile 'com.google.firebase:firebase-storage:10.0.1'
compile 'com.google.firebase:firebase-database:10.0.1'
compile 'com.google.android.gms:play-services:10.0.1'
compile 'com.android.support:multidex:1.0.0'
testCompile 'junit:junit:4.12'
}
apply plugin: 'com.google.gms.google-services'

我的logcat是：

看起来您已达到64K方法限制并需要启用multidex。 5.0以下的Android版本使用Dalvik，默认情况下只支持64K方法（包括库），Android 5.0及以上使用ART，默认情况下支持64K以上的方法。您可以在Android Developer网站上阅读有关multidex here的所有内容。

应用程序在Marshmallow上运行，但不在Jellybean上运行
