在基本模块中找不到动态功能模块中的Android提供程序 [英] Android Provider in Dynamic Feature module not found in Base Module

问题描述

我在动态功能模块中使用了一些库.这些库正在为清单添加一些提供程序.

I am using some libraries in my dynamic feature module. These libraries are Adding some providers to the manifest.

例如，在动态模块的build.gradle文件中:

For example in my build.gradle file in the dynamic module:

dependencies {
    ...
    implementation 'com.github.esafirm.android-image-picker:imagepicker:1.11.1'
    ...
}

该库将以下标记添加到清单中:

This library adds the following tag to the manifest:

<provider
        android:name="com.esafirm.imagepicker.helper.ImagePickerFileProvider"
        android:authorities="{$applicationId}.imagepicker.provider"
        android:exported="false"
        android:grantUriPermissions="true" >
        <meta-data
            android:name="android.support.FILE_PROVIDER_PATHS"
            android:resource="@xml/image_picker_provider_paths" />
</provider>

问题是当我构建基本模块时，应用程序崩溃，因为它找不到提供程序.我该如何解决?

The problem is when I build my base module the app crashes because it cannot find the provider. How can I solve this?

如此处所述:

您应用基本模块的清单与其他任何应用模块的清单相似.请记住，当Google Play生成您应用的基本APK时，它将所有模块的清单合并到基本APK的清单中.

The manifest for your app’s base module is similar to that of any other app module. Keep in mind, when Google Play generates your app’s base APK, it merges manifests for all modules into that of the base APK.

但是为什么只有提供者会受到影响?活动会被忽略吗?

But why only providers are affected? Are activities ignored?

这是我得到的堆栈跟踪:

This is the stacktrace I get:

推荐答案

尝试此解决方案.

在应用程序build.gradle中添加带有 tools:node ="remove" 的提供程序

Add provider with tools:node="remove" in you app build.gradle

<provider
        android:name="com.esafirm.imagepicker.helper.ImagePickerFileProvider"
        android:authorities="{$applicationId}.imagepicker.provider"
        android:exported="false"
        android:grantUriPermissions="true"
        tools:node="remove" >
        <meta-data
            android:name="android.support.FILE_PROVIDER_PATHS"
            android:resource="@xml/image_picker_provider_paths" />
</provider>

在Android Studio中，它将标记为红色，但是当您使用进行构建时

In Android Studio it will be marked as red but when you build bundle with

./gradlew clean bundleRelease 

它应该成功完成.

现在，您可以生成.apks文件并将其解压缩:

Now you can generate .apks file and unzip it:

java -jar bundletool-all-0.10.2.jar build-apks --bundle=app.aab --output=release.apks --ks=release.keystore --ks-pass=pass:xxxxxx --ks-key-alias=xxxxxxkey --key-pass=pass:xxxxxx

unzip release.apks

此后，您可以解码.apk文件(例如，使用apktool)以查看其清单.现在，在base-master.apk中，您应该看不到提供程序条目，而在{dynamic-module} master.apk中，它应该可用.

After this you can decode your .apk files (for example with apktool) to take a look at their manifests. Now in base-master.apk you shouldn't see your provider entries, and in {dynamic-module}master.apk it should be available.

java -jar apktool_2.4.0.jar d release/splits/base-master.apk
