5. Let’s Talk about the problem
6. Let’s Talk about the problem ચાલો શરૂ કરીએ ?
8. Module Bug Release Android Development Graph Feature
9. Solution to this ??
10. Multi - Modules
11. What and Whys of Multi Modules
12. Let’s talk about What
13. Let’s Talk about What Why
15. Library Modules Dynamic Delivery Modules
16. Library Modules Dynamic Delivery Modules
17. Let’s start with the code
18. Let’s start with the code
19. Create an Android Project (App Module)
20. Create an Android Project (App Module)
22. Create an Android Project (App Module) Goto File-> New -> New Module and select Dynamic Feature Module (>Kitkat)
24. On the next screen, you will get a few options to configure your module.
25. On the next screen, you will get a few options to configure your module.
26. Press Finish :)
27. Final Project Looks like :)
28. What we want to achieve ?
29. <RelativeLayout> <Button android:id="@+id/buttonClick"/> <Button android:id="@+id/buttonOpenNewsModule android:visibility="gone"/> <Button android:id="@+id/buttonDeleteNewsModule" android:visibility="gone"/> </RelativeLayout>
30. android { ....... dynamicFeatures = [":news_feature"] } In app’s build.gradle file
31. apply plugin: 'com.android.dynamic-feature' dependencies { ..... implementation project(':app') } In new_feature’s build.gradle file
32. <dist:module dist:instant="false" dist:onDemand="true" dist:title="@string/title_news_feature"> <dist:fusing dist:include="true"/> </dist:module> In the manifest of the dynamic Module,
33. <dist:module dist:instant="false" dist:onDemand="true" dist:title="@string/title_news_feature"> <dist:fusing dist:include="true"/> </dist:module>
34. <dist:module dist:instant="false" dist:onDemand="true" dist:title="@string/title_news_feature"> <dist:fusing dist:include="true"/> </dist:module>
35. implementation 'com.google.android.play:core:1.6.3' To make your module downloadable on demand add the following in the app-module's build.gradle,
36. Pro Tip #1 • Treat the dynamic-module as the individual app itself
37. dependencies { ..... api 'androidx.appcompat:appcompat:1.0.2' api 'androidx.constraintlayout:constraintlayout:1.1.3' implementation 'com.google.android.play:core:1.6.1' } In the manifest of the app’s module,
38. This is our project
39. dependencies { ..... api 'androidx.appcompat:appcompat:1.0.2' api 'androidx.constraintlayout:constraintlayout:1.1.3' implementation 'com.google.android.play:core:1.6.1' } In the manifest of the app’s module,
40. dependencies { ..... api 'androidx.appcompat:appcompat:1.0.2' api 'androidx.constraintlayout:constraintlayout:1.1.3' implementation 'com.google.android.play:core:1.6.1' } In the manifest of the app’s module,
41. Let's learn how to make the dynamic-feature downloadable from the app's module.
42. class MainActivity : AppCompatActivity() { lateinit var splitInstallManager: SplitInstallManager lateinit var request: SplitInstallRequest val DYNAMIC_FEATURE = "news_feature" override fun onCreate(savedInstanceState: Bundle?) { .... } } In App’s MainActivity
43. override fun onCreate(savedInstanceState: Bundle) { .... initDynamicModules() } private fun initDynamicModules() { splitInstallManager = SplitInstallManagerFactory.create(this) request = SplitInstallRequest .newBuilder() .addModule(DYNAMIC_FEATURE) .build(); } In App’s MainActivity
44. Implement Clicks :)
45. In App’s MainActivity override fun onCreate(savedInstanceState: Bundle) { ........ buttonClick.setOnClickListener { if (!isDynamicFeatureDownloaded(DYNAMIC_FEATURE)) { downloadFeature() } else { buttonDeleteNewsModule.visibility = View.VISIBLE buttonOpenNewsModule.visibility = View.VISIBLE } } }
46. In App’s MainActivity private fun isDynamicFeatureDownloaded(feature: String): Boolean = splitInstallManager.installedModules.contains(feature)
47. In App’s MainActivity private fun downloadFeature() { splitInstallManager.startInstall(request) .addOnFailureListener { //on Failure Handle } .addOnSuccessListener { buttonOpenNewsModule.visibility = View.VISIBLE buttonDeleteNewsModule.visibility = View.VISIBLE } .addOnCompleteListener { } }
49. Let’s Open the News Activity
50. In App’s MainActivity buttonOpenNewsModule.setOnClickListener { val intent = Intent() .setClassName(this, "com.mindorks.news_feature.newsloader.NewsLoaderActivity") startActivity(intent) }
51. In App’s MainActivity buttonOpenNewsModule.setOnClickListener { val intent = Intent() .setClassName(this, "com.mindorks.news_feature.newsloader.NewsLoaderActivity") startActivity(intent) }
52. In App’s MainActivity buttonDeleteNewsModule.setOnClickListener { val list = listOf(DYNAMIC_FEATURE) splitInstallManager.deferredUninstall(list) .addOnSuccessListener { buttonDeleteNewsModule.visibility = View.GONE buttonOpenNewsModule.visibility = View.GONE } }
53. Library Modules
54. Create an Android Project (App Module) Goto File -> New -> New Module
56. And Use it how you use other libraries :)
57. Pro Tip #2 • Checkout Darshan’s Talk to understand this module for the library creation
