The Java-Eeditor has a simple Android interface.
As a teacher you can use the Android Studio to create a hull project for your students and make it available for further work in the Java-Editor. The students can then expand the hull project in their familiar development environment Java Editor.
Android Studio install installs the Android SDK automatically.
Install the Android SDK only. On the page Install Android Studio scroll to Get just the command line tools and install the command line tools. These contain the SDK- manager with which you can install these components after:
sdkmanager "build-tools;25.0.2" sdkmanager "platforms;android-25" sdkmanager "platform-tools"
If no install happens even though a device is connected:
In case of the error message Cannot resolve symbol 'R' reduce the Graddle version to 2.0.0 in the file build-gradle, which is located in the project folder of the app.
In case of the error message signatures do not match the previously installed version; Ignoring delete the old version of the app on the phone.
The demo app MyFirstApp shows what is possible in the Java-Editor with Android mode.
For code completion download the file AndroidDocs.zip, unzip it and open the configuration via the Window menu. On the Java/Interpreter page, invoke Edit for JavaDoc-Folders and select the appropriate file from the unzipped zip file via allclasses-frame.html and save the changed settings.
