Samsung Flowを他のデバイスにインストールしたい（軌跡その1）

普段遣い端末とLINE専用端末（rooted）の2台持ちをしている。原因はLINEのトーク履歴のフルバックアップにはrootedであることが最低条件である、というクソ設計なのだが…それは置いとくとして。
2台持ちしているけれど、ズボンのポケットに2台必ず入れとくのも面倒なので、トイレに籠るときとかコンビニにちょっと行くときは、普段遣い端末のみ持っていったりするのだ。通知の同期についてはIFTTTで対応して、操作についてはAnyDeskというのを使っている。それなりに快適だったのだが、ちょっと動きのカクカクがしんどいのもあり、何か代替はないかな〜と思っていた。
すまほんにて、Samsung Flowというのが紹介されていた。
LINE Lite難民に朗報！Galaxy Tab S8+でスマホアプリが起動できる「Samsung Flow」
これはSamsungのタブレットからSamsungスマホを操作するためのアプリなので、別メーカーとか別端末で使えたら嬉しいのう、今の自分の需要にマッチするのう、と思ったわけ。
なので、今回は手元のLINE専用端末にSamsung Flowを導入したい、というお話。
結論としては、次回持ち越しという感じ…試行錯誤の軌跡である。

環境

操作端末（普段遣い）
- Galaxy S20（SC-51A）
  - Android12
  - 非root
被操作端末（LINE専用端末）
- LG-H930DS
  - Android8
  - rooted

試行錯誤

インストールしたい

被操作端末でPlayストアを開くと、非対応端末ということでインストールできない。
しょうがないのでApkpureを使ってSamsung Flowのapkをダウンロード。
取り敢えず何も考えずadb installすると、

$ adb install ./Samsung\ Flow_v4.8.07.4_apkpure.com.apk 
Performing Streamed Install
adb: failed to install ./Samsung Flow_v4.8.07.4_apkpure.com.apk: Failure [INSTALL_FAILED_MISSING_SHARED_LIBRARY: Package couldn't be installed in /data/app/com.samsung.android.galaxycontinuity-ka_8-Jhi5299MOONkEgP-w==: Package com.samsung.android.galaxycontinuity requires unavailable shared library com.samsung.device; failing!]

必要なライブラリが無いぜ、という感じ。

`com.samsung.device`を移植したい

ぐぐってると、10年前の記事だが似た話を発見
[DEV] Samsung Smart View (Welcoming more help) | XDA Forums

操作端末はSamsung端末で、こちらは普通にインストールできるので、ここからデータを抜き出して移植してみる。

$ adb pull /system/framework/com.samsung.device.jar ./
$ adb pull /etc/permissions/com.samsung.device.xml ./
$ adb push ./com.samsung.device.jar /storage/emulated/0/
$ adb push ./com.samsung.device.xml /storage/emulated/0/

/systemを読み書きでマウントしたい

TWRPを起こしてマウントメニューからsystemを読み取り専用チェックボックスを外した状態で選ぶ…選べない。
ログを見ると、

\'/system\'をマウントできませんでした (Structure needs cleaning)

と言われる…かなしい。
ぐぐって見つけた以下によると、systemを一旦Wipeして入れ直せば良いとのこと。
failed to mount /system structure needs cleaning

TWRPで、
消去→高度な消去→Systemを選んでスワイプ！
restore→てきとうなバックアップ→systemのみチェックして実施

死んでたら嫌なので一旦普通に起動して動作確認。
うまくいった気配があるので、ここでもう一度念の為のフルバックアップをとっておく。

`com.samsung.device`を移植

TWRPで、マウント→Systemにチェック

$ adb shell mount | grep system
/dev/block/sda18 on /system type ext4 (rw, seclabel,relatime,data=ordered)

読み書きでマウントいけてそう。
データねじ込み。

$ adb shell
$ cp /sdcard/com.samsung.device.jar /system/framework/
$ cp /sdcard/com.samsung.device.xml /system/etc/permissions/
$ chmod 644 /system/framework/com.samsung.device.jar
$ chmod 644 /system/etc/permissions/com.samsung.device.xml
$ reboot

apkインストールしてリベンジ

$ adb install ./Samsung\ Flow_v4.8.07.4_apkpure.com.apk

ほんでアプリを起動してみるとダメでした状態…
まずrootedだよという警告が出たので、Magisk ManagerでHideしてみたところ、エラー落ち。

てな感じで落ちる。データが見つかんねーよという落ち方だが…

順番に見ていこう

先頭の方でDMA not foundcom.sec.android.diagmonagent, non-samsung deviceみたいなメッセージがあるので、これも入れてあげないとかな〜？

〜〜SC-51A〜〜
$ adb shell pm list packages -f | grep diagmonagent
package:/system/priv-app/DiagMonAgent8/DiagMonAgent8.apk=com.sec.android.diagmonagent
$ adb pull /system/priv-app/DiagMonAgent8/DiagMonAgent8.apk ./

〜〜LG-H930DS〜〜
$ adb install DiagMonAgent8.apk
adb: failed to install DiagMonAgent8.apk: Failure [INSTALL_FAILED_OLDER_SDK: Failed parse during installPackageLI: /data/app/vmdl1411168067.tmp/base.apk (at Binary XML file line #8): Requires newer sdk version #28 (current version is #26)]

ｵｲｯｽ〜そういやGalaxy S20はAndroid12、移植先はAndroid8なので、さすがにこれ離れすぎだなという…

一旦おわり

午前2時を超えるともう眠い。
このままじゃダメなので、移植先のAndroidバージョンを上げるのが良さそう。
稼働しているLINEインスタンスがいるので、これのバックアップやデータ移行の手順を確立してから実施しないといけないね。ていうかLG-H930DS用の新しいバージョンのROMがあれば良いけれども、無ければ自分で作ることになるのか…？
