我尝试在我的应用程序中添加一个即时应用程序功能，但当作为即时应用程序启动我的应用程序时，我得到了以下错误：

RuntimeException:无法获得提供者android.support.v4.content.FileProvider: java.lang.SecurityException: provider必须授予uri权限

下面是它在我的feature声明中的用法：

<manifest>

    <application>

        <provider
            android:name="android.support.v4.content.FileProvider"
            android:authorities="${applicationId}.provider"
            android:exported="false"
            android:grantUriPermissions="true">

            <meta-data
                android:name="android.support.FILE_PROVIDER_PATHS"
                android:resource="@xml/provider_paths" />

        </provider>

    </application>

</manifest>

我的即时应用程序build.gradle：

apply plugin: 'com.android.instantapp'

android {
    compileSdkVersion rootProject.compileSdk

    defaultConfig {
        applicationId "applicationId" // same than my app's APK module
        minSdkVersion rootProject.minSdk
        targetSdkVersion rootProject.compileSdk
        versionCode rootProject.versionCode
        versionName rootProject.versionName
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }

    }
}
dependencies {
    implementation project(':feature') // app's feature
}

怎么啦？谢谢你的帮助。

看起来https://developer.android.com/training/secure-file-sharing/setup-sharing.html 在O上也不受支持，因为其他应用程序不允许查看它的ContentProvider。

我有一个测试应用程序，作为一个安装的应用程序，而不是作为一个https://developer.android.com/topic/instant-apps/faqs.html。看起来即时应用程序不允许使用grantUriPermission(授予URI权限)(考虑到即时应用程序对安装的应用程序不可见且ContentProvider不可见的策略，这是有意义的)。

这意味着即时应用程序不能检索使用ACTION_IMAGE_CAPTURE拍摄的照片(因为它们不能读取外部存储，而相机应用程序不能写入即时应用程序的私有存储空间)。
