这是一个敏捷问题.在Android 4.4中

It was a Dex problem. in android 4.4

1-在应用程序gradle中，在defaultConfig内启用multidex

1 - in app gradle, inside defaultConfig enable multidex

defaultConfig{
  ....
  multiDexEnabled true
}

2-要在其他版本中支持multidex，请将此依赖项添加到您的应用gradle中

2 - to support multidex in other versions, add this dependency to your app gradle

implementation 'com.android.support:multidex:1.0.3' 

3-如果您有一个扩展Application的类，请使其扩展

3 - if you have a class that extends Application, make it extend

MultiDexApplication

MultiDexApplication

如果不这样做，请将其添加到应用程序标记内的清单文件中

if you don't, add this to your manifest file inside application tag

android:name="android.support.multidex.MultiDexApplication" 

此外，如果您创建了一个新应用程序，请不要忘记将以下内容添加到您的app/build.gradle

Besides, if you created a new application, dont forget to add the following to your app/build.gradle

android {
    defaultConfig {
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
}

就是这样.为我工作
