I tried adding an instant app feature to my app, but when launching my app as an instant app I'm getting this error :

RuntimeException: Unable to get provider android.support.v4.content.FileProvider: java.lang.SecurityException: Provider must grant uri permissions

Here is how it's used in my feature Manifest:

<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>

And my 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
}

What is wrong? Thanks for your help.

It looks like the FileProvider isn't supported on O either because other apps aren't allowed to see its ContentProvider.

I have a test app that works as an installed app but not as an instant app. It looks like instant apps aren't allowed to use grantUriPermission(grant URI permissions) (which makes sense given the policy that instant apps can't be visible to installed apps and ContentProvider is not visible).

This means that instant apps can't retrieve pictures taken with ACTION_IMAGE_CAPTURE (because they can't read external storage and the camera app can't write to instant apps' private storage).

  • It seems to be the actual problem, I solved it by removing this part of the base `Manifest` and putting it in the APK's `Manifest`. – Rob Feb 15 '18 at 09:36

Add grantUriPermissions and exported in your AndroidManifest.xml file.

        <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>
