Adb

Un toot sur Mastodon a attiré mon attention sur adb qui permet apparemment de supprimer les applications qu'on ne sait pas supprimer depuis l'interface d'android (mais uniquement désactiver) comme Facebook, les Google Apps, etc..

Mettre son smartphone en "mode debug"

Frandroid nous indique comment activer le “mode développeur”.

Il faut aller dans les Paramètres, puis dans À propos du téléphone et toucher 7 fois la case Numéro de build. Le menu Options pour les développeurs apparaît alors dans les paramètres systèmes. (Ça donne l'impression d'être une mauvaise astuce pour un jeux vidéo, mais ça marche…)

Dans le menu pour les développeurs, on trouve une option “Débogage USB” qu'on peut activer.

Installer adb

$ sudo apt install adb

J'ai eu des erreurs de permissions dans certains cas :

$ adb devices
List of devices attached
ZY909667	no permissions (user in plugdev group; are your udev rules wrong?); see [http://developer.android.com/tools/device.html]

J'ai trouvé la solution là : https://www.janosgyerik.com/adding-udev-rules-for-usb-debugging-android-devices/

Jouer avec adb

Liste des appareils branchés

J'ai du lancer plusieurs fois la commande :

$ adb devices
List of devices attached
* daemon not running. starting it now on port 5037 *
free(): invalid next size (fast)
ADB server didn't ACK
* failed to start daemon *
error: cannot connect to daemon
 
$ adb devices
List of devices attached
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
BJ030262	unauthorized

Un pop-up apparait sur le téléphone pour demander si on autorise l'accès à cet ordinateur. Une fois qu'on a validé, on peut relancer la commande :

$ adb devices
List of devices attached
BJ030262	device

Voir les logs du téléphone

La commande “logcat” permet de voir les logs du téléphone mais ça spamme vraiment beaucoup…

$ adb logcat

Se connecter sur le téléphone

$ adb shell

    -f: install application on internal flash
    -d: allow version code downgrade (debuggable packages only)
    -p: partial application install
    -g: grant all runtime permissions
    -S: size in bytes of entire session
 
pm install-write: write a package into existing session; path may
  be '-' to read from stdin
    -S: size in bytes of package, required for stdin
 
pm install-commit: perform install of fully staged session

  these commands change the enabled state of a given package or
  component (written as "package/class").
 
pm grant, revoke: these commands either grant or revoke permissions

    and the app targeting SDK greater than Lollipop MR1.
 
pm reset-permissions: revert all runtime permissions to their default state.
 
pm get-install-location: returns the current install location.
    0 [auto]: Let system decide the best location
    1 [internal]: Install on internal device storage
    2 [external]: Install on external media
 
pm set-install-location: changes the default install location.
  NOTE: this is only intended for debugging; using this can cause
  applications to break and other undersireable behavior.
    0 [auto]: Let system decide the best location
    1 [internal]: Install on internal device storage
    2 [external]: Install on external media
 
pm trim-caches: trim cache files to reach the given free space.
 
pm create-user: create a new user with the given USER_NAME,
  printing the new user identifier of the user.
 
pm remove-user: remove the user with the given USER_IDENTIFIER,
  deleting all data associated with that user

L'option “–user 0” semble indispensable. Il y a également l'option “-k” qui permet de garder les données et caches du programme.

Après avoir désinstallé Chrome, j'étais à 8,78 Go utilisé par les applications. On continue! Hop, on vire “Google Musique” :

bardock:/ $ pm uninstall --user 0 com.google.android.music                                               
Success

Le plus compliqué reste de trouver le nom du package à supprimer. On peut chercher avec dumpsys, comme par exemple pour Google Vidéos :

$ dumpsys | grep -A 50 "Package .*videos" 
(...)
versionName=4.1.6.13

On peut alors comparer dans le menu et vérifier que la version correspond.

Upgrade LineageOS

Mettre à jour LineageOS : https://wiki.lineageos.org/devices/bardock/upgrade

$ adb root
$ adb reboot sideload
$ adb sideload lineage-17.1-20210316-nightly-bardock-signed.zip 
serving: 'lineage-17.1-20210316-nightly-bardock-signed.zip'  (~47%)    adb: failed to read command: Success

La dernière fois, je n'ai pas réussis à lancer la commande “adb sideload …”, j'ai du copier le fichier sur le téléphone et lancer l'installation directement depuis TWRP.
