加載動態功能時出錯。 應用程式套件Android

Question

在Android API級別（26（奧利奧）及以上）中，我遇到此錯誤。 如果我從android studio直接向設備運行動態功能，則動態功能可以正常運行，但是當我在Play商店上載應用捆綁銷售商品並嘗試從Play商店下載的應用中運行動態功能時，

運行時異常：每個資源（string.xml，atrr.xml等）上的Resources $ NotFoundException。

在Android API級別以下，其26正常工作。

錯誤日志：

Answer 1

如果活動是在動態功能中定義的，則需要在attachBaseContext方法中調用SplitCompat.install(this)以確保所有新資源可用於您的應用程序。

Answer 2

您可以看一下此示例中如何實現動態功能。

有關如何從基本模塊中打開動態模塊中的某些資源的示例代碼。

另外，樣本還包括其他動態模塊，這些模塊具有以Java / Kotlin和本機實施的活動。

請記住，playcore v1.3.4包含一個類似錯誤的修復程序。 確保使用v1.3.4或更高版本。 另一個要求是在動態模塊中的活動中覆蓋attachBaseClassContext ：

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

這是在帶有此抽象類的示例中顯示的。

Answer 3

我可以確認@pfmaggi提供的解決方案是正確的。

當您傳遞應用程序上下文時，它可以工作，因此您需要執行以下操作：

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

然后在基礎模塊的清單中添加應用程序名稱（注意：將應用程序名稱添加到名為“ app”的模塊的清單文件中，或在build.gradle文件中的帶有Apply apply plugin: 'com.android.application'的模塊中）
