Android API Levels

To set al these levels, go to File > Project Structure from
the menu bars at the top of Android Studio:

You can set API levels for your apps. The idea is that you set a minimum
API level that your app runs on, and the version that your app was compiled
for (this is the Target SDK Version). You can also set something called
the Build Tools version.

To set al these levels, go to File > Project Structure from
the menu bars at the top of Android Studio:

From the dialog box that appears, Click on Modules, then app
in the middle. On the Properties tab, look for the Compile
Sdk Version
and the Build Tools Version:

Android Studio 3.5 only goes up to API 28, which is fine. But this is Android
9.0 (Pie). Android 10 is out, though, and this is API 29. You need Android
Studio 3.3 or higher to test your apps for Android 10. Even then, you
may get errors about Gradle sync failures and warnings about outdated
dependencies. Furture versions of Android Studio versions will probably
have full support for 10. When it does, you’ll see it API 29 in the
dropdown box.

For both of these dropdown boxes, Compile Sdk Version and Build Tools
Version, select the highest ones. Click Apply and OK and you’re done.

Now have a look at the build.gradle file in the project files
area on the left:

Double click the build.gradle to open it up. You should see
something like this:

You can actually type in the various API and Build levels here, rather
than open up the dialog box. (The dialog box just adds the values here,
in this file.) In the image above, you can see that the compileSdkVersion
is 28, while the buildToolsversion is 29.0.1. The minimum SDK
version is set to 15 while the targetSdkVersion is 28,

Click the Open Project Structure link in the top right to see the dialog
box again.

Notice the dependencies area at the bottom. You can add your own here,
if you need to.


And that’s it for this section. Try to adapt the app. Add some content for
the webpages. Or change the grid view images and headings to something
of your own choosing. You’ll probably see lots of apps in the Google
Play store that use a GridView and WebView. You can now add your own!
