android studio上的程序无法在旧设备（Android 6及更低版本）上运行，是否有功能指定最低版本？

Question

i wrote an application on Android Studio, news feed on firebase from google (i'm beginner in Android). The program works fine, but only on the lastest versions of Android. Is there a function to indicate the version (in the code i used ViewPager, TableLayout,, maybe they only work on new devices?)

Answer 1

Is there a function to indicate the version

This is controlled by minSdkVersion , set in your app module's build.gradle file (eg, app/build.gradle for a typical Android Studio starter project).

in the code i used ViewPager, TableLayout,, maybe they only work on new devices?

TableLayout has existed since Android 1.0. ViewPager works back to Android 4.0.

在android部分下的build.gradle文件中，有一个名为compileSdkVersion的字段，对其进行更改以更改最小的API
