加载动态功能时出错。 应用程式套件Android

Question

In Android API level, 26 (Oreo) and above I am getting this error. If I run dynamic feature from android studio direct to the device, the dynamic feature works fine, but when I upload app bundle on play store and try to run dynamic feature from the app which downloaded from play store I am getting

Runtime Exception: Resources$ NotFoundException on every resource (string.xml, atrr.xml etc).

Below Android API level, 26 its working fine.

Error Log:

Answer 1

如果活动是在动态功能中定义的，则需要在attachBaseContext方法中调用SplitCompat.install(this)以确保所有新资源可用于您的应用程序。

Answer 2

You can take a look at how Dynamic Features are implemented in this sample .

There's sample code on how to open some resources, located in a dynamic module, from the base module .

Plus, the samples includes others dynamic modules with activities implemented in Java/Kotlin and native.

Keep in mind that playcore v1.3.4 includes a fix a similar bug. Be sure to use v1.3.4 or newer. The other requirement is to override the attachBaseClassContext in the activities you've in the dynamic modules:

override fun attachBaseContext(newBase: Context?) {
    super.attachBaseContext(newBase)
    SplitCompat.install(this)
}

This is shown in the sample with this abstract class.

Answer 3

I can confirm that the solution provided by @pfmaggi is correct.

It works when you pass the application context, so you have do something like:

class MyApplication: SplitCompatApplication() {
...
    override fun attachBaseContext(newBase: Context?) {
        super.attachBaseContext(newBase)
        SplitCompat.install(this)
    }
...
}

and then add the application name in Manifest of your base module ( Note: add application name to the manifest file in your module named 'app' or the module with apply plugin: 'com.android.application' in its build.gradle file )
