spoon: IllegalAccessException: Unable to create output dir: /storage/emulated/0/app_spoon-screenshots

Spoon fails since dir.mkdirs() returns false…

if(!dir.exists() && !dir.mkdirs()) {
    throw new IllegalAccessException("Unable to create output dir: " + dir.getAbsolutePath());
} else {
    Chmod.chmodPlusRWX(dir);
}

I’ve given WRITE_EXTERNAL_STORAGE permissions in the AndroidManifest.xml and also tried using the GrantPermissionRule, but it keeps failing at that same step. Any help would be greatly appreciated.

similar issue shows up when targeting api 29. I suspect the scoped storage changes are the cause.

Until this is fixed, you can use: android:requestLegacyExternalStorage="true"

Put it in the <application> tag in AndroidManifest.xml. This will only work when targeting API 29.

I hope this issue is fixed until API 30 targeting becomes a requirement.

Figured out my issue! My issue was caused by an external library merging in the maxSdkVersion with the WRITE_EXTERNAL_STORAGE permission. To get around this I removed the attribute and re-added the WRITE_EXTERNAL_STORAGE permission. This is only needed for my application manifest and not the test application manifest.

<!-- Strip away maxSdkVersion -->
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"
                 tools:remove="android:maxSdkVersion"/>
    
<!-- Add the permission with no maxSdkVersion defined -->
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

Then you can build, grant permissions, and run the tests:

# Uninstall existing APKs and install our app APK and test APK
./gradlew uninstallAll installDebug installDebugAndroidTest

# List all APKs installed with adb shell 'pm list packages -f'
# Grant the app APK write and read to external storage permissions
adb shell pm grant gg.mark.debug android.permission.WRITE_EXTERNAL_STORAGE
adb shell pm grant gg.mark.debug android.permission.READ_EXTERNAL_STORAGE

export APK=build/outputs/apk/debug/debug.apk
export TEST_APK=build/outputs/apk/androidTest/debug/debug-androidTest.apk

# TEST_APK and APK are positional arguments so keep them in this order
# Disable GIF generation because it's slow
java -jar spoon-runner-2.0.0.jar --debug --disable-gif "$TEST_APK" "$APK"

The pm grant commands will fail if the permissions for your app are not set up properly. Make sure those commands succeed!

Thanks for the help @tnainani! 😄

add the following to your test class:

@Rule public GrantPermissionRule mRuntimePermissionRule = GrantPermissionRule.grant(Manifest.permission.WRITE_EXTERNAL_STORAGE,
            Manifest.permission.READ_EXTERNAL_STORAGE);
