Guide: Steps for adding Xiaomi devices to STF (e.g. Xiaomi Redmi 4A , MIUI 8.2.6.0) #603

Open sorccu opened 7 years ago

sorccu commented 7 years ago

To add Xiaomi devices to STF, there are extra steps that must be taken.

  1. To enable Developer options, to go Settings → About phone and tap on MIUI version until it says developer mode has been turned on.
  2. Go to Settings → Mi Account and create or log in to a Mi account. This is required for the next step.
  3. Go to Settings → Additional settings → Developer options. Turn USB debugging (for ADB access), Install via USB (needed for installing STFService.apk) and USB debugging (Security settings) (needed for running minitouch) on. You must have a MI account set up to enable USB debugging (Security settings), otherwise it won't let you.
    • Note: there are reports that some versions of MIUI may require a SIM card or these settings can't be turned on.
  4. Connect the device to your computer. Allow the ADB key and select "Always allow."
  5. Run STF. A dialog will pop up on the device confirming installation of STFService. You must allow the installation to go through. Note that you may need to do this again in the future if the service is updated.
  6. If STF fails to start after installing STFService.apk, go to Settings → Permissions → Autostart and enable STFService.
  7. The device should now work in STF.

Common errors:

If you see an error that says:

Setup had an error Error: /data/local/tmp/STFService.apk could not be installed [INSTALL_CANCELED_BY_USER]

It means that you haven't enabled the Install via USB option.

Steps tested on:

Redmi 4A

iqianxing commented 6 years ago

The device requires sim card in the device. If doesn't, Install via USB (needed for installing STFService.apk) and USB debugging (Security settings) (needed for running minitouch) can't on.

sorccu commented 6 years ago

Hmmmm that's weird, I don't have a SIM card in mine. Which device and MIUI version is it?

iqianxing commented 6 years ago

MIUI 8.5.1.0

sorccu commented 6 years ago

Strange... does it actually tell you that you need a SIM card?

iqianxing commented 6 years ago

Yes , perhaps the os is different in China.

sorccu commented 6 years ago

Possible. I've added your findings to the guide.

lukassos commented 6 years ago

Any update on this matter ? Same issue here. I need sim card inside the phone to install/dev apps on the phone too. I have unpacked new Redmi Note 5A with android 7.1.2 N2G47H (2017-12-01) and MUIU 9.2.1.0 NDFMIEK and the issue persist . In android studio INSTALL_FAILED_USER_RESTRICTED, which implies the admin app has not permitted such operation. And in Xiaomi phone it is part of MIUI as I recall.

sorccu commented 6 years ago

What kind of an update are you looking for? If the manufacturer forces you to set up a SIM card there’s nothing we can do about that.

lukassos commented 6 years ago

You're right. There is nothing you can add to this matter. I have researched about it a bit more and this is really an issue of MIUI 8+. They have added verification on chinese servers and gather unique id (UUID) of the phone on unlock of unknown souce apk. This UUID is generated from sim card secure element and thus you need a sim card indeed. Foremost thanks for really fast answer 😉 So for anybody else reading this, you need any sim card inside. There is no need for sim card to be active on cellular. On the other hand internet connection is required too.

Linux机器使用docker搭建STF，Windows安装SDK后，使用USB连接安卓设备 首先在Windows暴露5037端口 然后在Linux使用命令：stf provider --name localhost.localdomain --min-port 7400 --max-port 7700 --connect-sub tcp://172.50.1.159:7114 --connect-push tcp://172.50.1.159:7116 --group-timeout 900 --public-ip 172.50.1.159 --storage-url http://172.50.1.159:7100/ --adb-host 172.17.244.11 --adb-port 5037 --vnc-initial-size 600x800 --mute-master never --allow-remote

就一直停在“ tcp://172.50.1.159：7114”接收输入，过了几分钟就报错了，这个是什么原因? 2021-05-26_104418 2021-05-26_105530

It seems MI OS's power saving strategy produce this error. I chose no restriction strategy for power saving, and it works.
