Resource Not Found Relaunch Application on-Demand Dynamic Feature Module

[Faisal-Naseer]

When I download the on demand dynamic feature module it works fine as soon as I restart application I get the crash "Resource not found" . Heres the code that i copied from google dynamic features sample repo

private fun onSuccessfulLoad(moduleName: String, launch: Boolean) {
    if (launch) {
        when (moduleName) {
           pagesfeatures -> launchActivity(mainActivity)
        }
    }

}

I have already overridden the code in BaseActivity and App class

 open class BaseActivity: AppCompatActivity() {
    override fun attachBaseContext(newBase: Context?) {
        super.attachBaseContext(newBase)
        SplitCompat.install(this)
    }
}
 public class App extends Application {
    @Override
    protected void attachBaseContext(Context base) {
        super.attachBaseContext(base);
        SplitCompat.install(base);
    }
}

But its crashing when i revisit the application

The Exception thats occurring in my logs Crashlytics

The same problem happened to our app. But still no solution.

There are some clues:

1. After call SplitCompat.install(context) at Application.attachBaseContext, the applicationContext.resource.asserts do have contain the dynamic module apk (on-demand)
2. Then the WebView apk loaded, it refreshed the ResourcesImpl instance. At then, applicationContext.resource.asserts don't contain the dynamic module apk (on-demand)
3. We guess that the installed dynamic module apk (on-demand) must be injected manually by calling SplitCompat.install every time the ResourcesImpl created, So after Step 2, the new ResoucesImpl instance don't contain the dynamic module apk (on-demand)

Don't know why Android team is no more interested in stability of such features... They always move to new stuff and leaving unresolved the old stuff

I have the same problem in my app, the resources of the third-party aar in the dynamic feature module cannot be found.

Our Solution: We monitor the property assert of resources(Application), and call SplitCompat.install() every time the assert changed in method getResources (Application)
