我尝试在我的应用程序中添加一个即时应用程序功能，但是在启动我的应用程序作为即时应用程序时，我会遇到此错误：
runtimeException：无法获得提供商Android.support.v4.content.fileprovider：java.lang.securityexception：提供商必须授予URI Permissions
这是我的feature清单中使用的方式：
<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>
和我的Instant-App 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
}
怎么了？感谢您的帮助。

看起来像 FileProvider 不支持O 要么因为其他应用程序不允许看到其 ContentProvider 。
我有一个测试应用程序，可以用作已安装应用程序，但不作为 Instant App 。看起来 Instant Apps 不允许使用grantUriPermission(Grant URI权限((考虑到即将安装的应用程序无法看到即时应用程序，并且ContentProvider不可见，这是有意义的。(。
这意味着即时应用程序无法检索ACTION_IMAGE_CAPTURE拍摄的图片(因为它们无法读取外部存储，而相机应用程序无法写入即时应用程序的私人存储(。
在您的AndroidManifest.xml文件中添加grantUriPermissions和exported。
<provider
android:exported="false"
android:grantUriPermissions="true"
android:authorities="${applicationId}.fileprovider"
android:name="androidx.core.content.FileProvider">
<meta-data
android:resource="@xml/file_paths"
android:name="android.support.FILE_PROVIDER_PATHS"
/>
</provider>
