Answer 1

第一个变体

您的问题是由错误使用multidex引起的。所以你的应用会在21+接口下正常工作，并且会导致低接口下的NoClassDefFoundError。

您的build.gradle文件中包含以下内容

defaultConfig {
applicationId "com.example.binarystore.project1"
minSdkVersion 16
targetSdkVersion 25
versionCode 1
versionName "1.0"
multiDexEnabled true
testInstrumentationRunner 
"android.support.test.runner.AndroidJUnitRunner"
}

您知道，multiDexEnabled true选项仅适用于21+接口，对于较旧的API，您需要在依赖项中包含此行compile 'com.android.support:multidex:1.0.1'。并将此代码添加到您的应用程序代码中

@Override
protected void attachBaseContext(Context base) {
 super.attachBaseContext(base);
 MultiDex.install(this);
}

有关使用multidex的详细信息，请查看here。

第二个变种

您正在调用使用@TargetApi(..M)注释在手机上声明的方法，该方法与版本要求不匹配。将版本检查添加到代码中，然后调用另一个方法，或者不调用任何方法。看一下这一行，当你想在19. Method refference上使用它时，你会发现错误，你可以找到只在23api中引入的"setOnScrollChangeListener“方法。

我建议你不要使用compile 'com.google.android.gms:play-services:....'，因为它会将所有的播放服务添加到你的项目中，并显著增加你的代码库和应用程序的大小。试着只添加你正在使用的模块。有关详细信息，请阅读this文章

Answer 2

在依赖项中使用compile 'com.android.support:multidex:1.0.1'
