I wrote this short tutorial because extending my internal storage using my new micro SD card on my Retroid Pocket 2+ failed all the time. Only setting it up as portable/external worked. However, this instructions should work in any Android 5.0+ device.

So, in case you have problems setting up your SD card on your Android device via graphical interface (setting up storage as extended internal memory or portable), and you get a corrupted SD card or any other error, follow these steps to fix it via adb shell:

Make sure you have adb access to your Android device: Settings > System > About, touch/click on Build number until Developer options are enabled:
Go to Settings > System > Developer options and enable USB debugging.
Assuming you have adb installed on your remote terminal run the following:

adb shell

Connecting to Cloudflare WARP with WireGuard

Cloudflare's WARP VPN uses a slightly modified version of the WireGuard protocol, but it remains backwards compatible with the normal WireGuard client software. This means you can connect to it on platforms which don't yet have an official WARP client, e.g. your computer or EdgeOS-based router.

Step 1

Generate a WireGuard keypair, as usual:

wg genkey | tee private.key | wg pubkey > public.key

None of these suggestions worked for me, because Android was appending a sequence number to the package name to produce the final APK file name (this may vary with the version of Android OS). The following sequence of commands is what worked for me on a non-rooted device:

Determine the package name of the app, e.g. com.example.someapp. Skip this step if you already know the package name.

adb shell pm list packages

Look through the list of package names and try to find a match between the app in question and the package name. This is usually easy, but note that the package name can be completely unrelated to the app name. If you can't recognize the app from the list of package names, try finding the app in Google Play using a browser. The URL for an app in Google Play contains the package name.
