Infinum Android Talks #15 - Garfield Android Studio Plugin - Be Smart, Be Lazy
1 like560 views
The document discusses the Garfield Android Studio plugin, which aims to reduce boilerplate code through code automation and generation. It allows developers to save templates for common code patterns that can be inserted with auto-complete. This helps avoid writing repetitive code manually and saves development time. The plugin is created using the IntelliJ platform and its action system and UI components. It also utilizes the Android facet and libraries like JavaPoet to programmatically generate code.
![How about this…
public static void sendEmail(String email, String subject,
String emailBody, List<Uri> images) throws
ActivityNotFoundException {
Intent intent = new Intent(Intent.ACTION_SEND_MULTIPLE);
intent.putExtra(Intent.EXTRA_EMAIL,
new String[]{email});
intent.putExtra(Intent.EXTRA_SUBJECT, subject);
intent.putExtra(Intent.EXTRA_TEXT, emailBody);
intent.putParcelableArrayListExtra(Intent.EXTRA_STREAM,
(ArrayList<Uri>) images);
intent.setType(TEXT_PLAIN);
startActivity(intent);

![SETUP
• git clone IntelliJ community edition
• run sh getPlugins.sh from the terminal (android studio
plugin included into community project)
• create a new Java SDK “IDEA jdk” (and add libtools.jar
to the classpath if needed)
• make project
• create a new Intellij Platform Plugin

Infinum Android Talks #15 - Garfield Android Studio Plugin - Be Smart, Be Lazy
- 1. Garfield Android Studio Plugin MIROSLAV POPOVIC Be smart, be lazy
- 2. PROBLEM Lot’s of boiler plate code out there
- 3. BOILERPLATES • Send email • Send sms • Mark pin on a map • Dagger • … Lot’s of lines of code needed for one logical operation
- 4. SOLUTION
- 5. CODE AUTOMATION Let the machine do the dirty work
- 6. SOLUTION
- 8. How about this… private static void setMarkerOnMap(@DrawableRes int resMarkerIcon, LatLng latLng, GoogleMap map) { MarkerOptions marker = new MarkerOptions().position(latLng) .icon(BitmapDescriptorFactory .fromResource(resMarkerIcon)); map.addMarker(marker); }
- 9. How about this… public static void sendEmail(String email, String subject, String emailBody, List<Uri> images) throws ActivityNotFoundException { Intent intent = new Intent(Intent.ACTION_SEND_MULTIPLE); intent.putExtra(Intent.EXTRA_EMAIL, new String[]{email}); intent.putExtra(Intent.EXTRA_SUBJECT, subject); intent.putExtra(Intent.EXTRA_TEXT, emailBody); intent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, (ArrayList<Uri>) images); intent.setType(TEXT_PLAIN); startActivity(intent); }
- 10. • Save a template • Auto complete • Export is possible LIVE TEMPLATES
- 11. android.content.Intent view = new Intent(); view.setAction(Intent.ACTION_VIEW); view.setData(android.net.Uri.parse($url$)); startActivity(view); LIVE TEMPLATES
- 12. Can - static code - variables - modification scripts LIVE TEMPLATES Cannot - generate packages - generate classes - check members
- 14. ANDROID STUDIO PLUGIN - GARFIELD Dagger, MVP, helper code…
- 15. WRITING CODE THAT GENERATES CODE Garfield Android Studio plugin 1) 2) 3) 4) with Garfield 5) Garfield exported
- 16. SETUP • git clone IntelliJ community edition • run sh getPlugins.sh from the terminal (android studio plugin included into community project) • create a new Java SDK “IDEA jdk” (and add libtools.jar to the classpath if needed) • make project • create a new Intellij Platform Plugin [1] git://git.jetbrains.org/idea/community.git 1
- 17. CREATING AN ACTION • Define an Action • Package com.intellij.openapi.actionSystem • Register in plugin.xml public class NewAction extends AnAction { public void actionPerformed(AnActionEvent e) { Project project = e.getProject(); Module module = e.getData(DataKeys.MODULE); NewForm form = new NewForm(project, module); form.show(); } }
- 18. CREATING UI • Common Swing UI components • You will most probably use a dialog • DialogWrapper used with UI Designer form @Nullable @Override protected JComponent createCenterPanel() { return rootPanel; }
- 19. ANDROID FACET • Needed to get base project name • IntelliJ Facets: Android, GWT, EJB, Hibernate public static String getPackageName(Project project, Module module) { AndroidFacet facet = getCurrentFacet(project, module); VirtualFile manifestFile = AndroidRootUtil.getPrimaryManifestFile(facet); Manifest manifest = AndroidUtils.loadDomElement(facet.getModule(), manifestFile, Manifest.class); return manifest.getPackage().getValue(); //get package }
- 20. GENERATING CODE ← JAVAPOET MethodSpec main = MethodSpec.methodBuilder("main") .addModifiers(Modifier.PUBLIC, Modifier.STATIC) .returns(void.class) .addParameter(String[].class, "args") .addStatement("$T.out.println($S)", System.class, "Hello, JavaPoet!") .build(); TypeSpec helloWorld = TypeSpec.classBuilder("HelloWorld") .addModifiers(Modifier.PUBLIC, Modifier.FINAL) .addMethod(main) .build(); public final class HelloWorld { public static void main(String[] args) { System.out.println("Hello, JavaPoet!"); } }
