RuntimeException: cannot create output directory dir: / storage / emulated / 0 / app_spoon-screenshots

I am configuring Spoon for Android UI Testing using the gradle-spoon-plugin using the Spoon 2.0.0 snapshot. My project is configured using the Android Gradle 3.0.1 plugin.

When spoonRule.screenshot(activity, "hello")taking screenshots using spoonRule.screenshot(activity, "hello")I get the following RuntimeException:

java.lang.RuntimeException: Unable to create output dir: /storage/emulated/0/app_spoon-screenshots
at com.squareup.spoon.SpoonRule.createDir(SpoonRule.java:167)
at com.squareup.spoon.SpoonRule.createDir(SpoonRule.java:164)

at com.squareup.spoon.SpoonRule.obtainDirectory(SpoonRule.java:108)
at com.squareup.spoon.SpoonRule.screenshot(SpoonRule.java:66)

Everything works well if I run it on the Nexus 4 API 19 emulator, but it does not work on the Pixel 2 API 27 emulator. Permissions changed from 19 to 27, so this is not entirely unexpected.

I have tried most of the tips currently available, including adding a manifest to my directory androidTestwhich provides external storage for reading and writing (with maxSdkVersionand without maxSdkVersion):

<?xml version="1.0" encoding="utf-8"?>
<manifest
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    package="tv.twitch.android.test">

    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" android:maxSdkVersion="18"/>
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" android:maxSdkVersion="18"/>

    <uses-sdk tools:overrideLibrary="android.support.test.uiautomator.v18"/>

</manifest>

I see that these permissions are combined in my last manifest of my AndroidManifest application (you don’t know how to check the manifest of the test application) in both cases.

I tried to grant permissions through UIAutomator for both the application and the test suite:

val device = UiDevice.getInstance(getInstrumentation())
device.executeShellCommand("pm grant tv.twitch.android.test android.permission.READ_EXTERNAL_STORAGE")
device.executeShellCommand("pm grant tv.twitch.android.debug android.permission.READ_EXTERNAL_STORAGE")
device.executeShellCommand("pm grant tv.twitch.android.test android.permission.WRITE_EXTERNAL_STORAGE")
device.executeShellCommand("pm grant tv.twitch.android.debug android.permission.WRITE_EXTERNAL_STORAGE")

This outputs Permission deniedLogcat, and results in the same exception described above.

If I try to use GrantPermissionRulelike:

@get:Rule var runtimePermissionRule = GrantPermissionRule.grant(Manifest.permission.READ_EXTERNAL_STORAGE, Manifest.permission.WRITE_EXTERNAL_STORAGE)

I get another exception:

junit.framework.AssertionFailedError: Failed to grant permissions, see logcat for details
at junit.framework.Assert.fail(Assert.java:50)
at android.support.test.runner.permission.PermissionRequester.requestPermissions(PermissionRequester.java:110)
at android.support.test.rule.GrantPermissionRule$RequestPermissionStatement.evaluate(GrantPermissionRule.java:108)

GrantPermissionCallable: Permission: android.permission.WRITE_EXTERNAL_STORAGE cannot be granted!

Removing Manifest.permission.WRITE_EXTERNAL_STORAGEand leaving only what is read returns us to the original exception:java.lang.RuntimeException: Unable to create output dir: /storage/emulated/0/app_spoon-screenshots
