Hail is a free-as-in-freedom software to freeze Android apps. [GitHub Releases](https://github.com/aistra0528/Hail/releases)
[
](https://f-droid.org/packages/com.aistra.hail/)
## Freeze
Freeze is a word that describes the action of **blocking (immediately stopping) apps when they are not needed/in-use (on-demand request)** which in turn helps the device to cut down on the usage of RAM and save power. Users can also unfreeze them to revert to their original state.
In general, "freeze" means disable, but also Hail can "freeze" apps by hiding and suspending them.
### Disable
Disabled apps will not be shown in the launcher and will be shown as "Disabled" in the installed apps list. Enable them to revert the action.
### Hide
Hidden apps will not be shown in the launcher and in the installed apps list. Unhide them to revert the action.
> While in this state, which is almost like an uninstalled state, the package will be unavailable, however, the application data and the actual package file will not be removed from the device.
### Suspend (Android 7.0+)
Suspended apps will have their icons shown in grayscale within the device's launcher. Unsuspend them to revert the action.
> While in this state, the application's notifications will be hidden, any of its started activities will be stopped and it will not be able to show toasts, dialogs or even play audio. When the user tries to launch a suspended app, the system will, instead, show a dialog to the user informing them that they cannot use this app while it is suspended.
Suspend only prevents the user from interacting with the app, it does **NOT** prevent the app from running in the background.
## Working mode
**Any app that has been frozen on Hail will need to be unfrozen by the same working mode.**
1. For devices supporting wireless debugging (Android 11+) or rooted devices, `Shizuku` is recommended.
2. For rooted devices, `Root` is an alternative. **It is slower.**
| Privilege | Force Stop | Disable | Hide | Suspend | Uninstall/Reinstall (System Apps) |
|---------------------------------------------------------------------------------------------------|------------|---------|------|---------|-----------------------------------|
| Root | ✓ | ✓ | ✓ | ✓ | ✓ |
| Device Owner | ✗ | ✗ | ✓ | ✓ | ✗ |

### Device Owner
**You must remove Hail as a device owner before you can uninstall it**
#### Set device owner by adb
[Android Debug Bridge (adb) Guide](https://developer.android.com/studio/command-line/adb)
[Download Android SDK Platform-Tools](https://developer.android.com/studio/releases/platform-tools)
Issue adb command:
```shell
adb shell dpm set-device-owner com.aistra.hail/.receiver.DeviceAdminReceiver
```
In response, adb prints this message if device owner has been successfully set:
```
Success: Device owner set to package com.aistra.hail. Active admin set to component {com.aistra.hail/com.aistra.hail.receiver.DeviceAdminReceiver}
```
Search the message by search engine otherwise.
#### Remove device owner
Settings > Remove Device Owner
### Privileged System App
The following privapp-permissions is required:
```xml
```
To use this mode, you should install Hail as a privileged system app.
The recommended approach is to import Hail when building your ROM, here's an example for `Android.bp`:
```bp
android_app_import {
name: "Hail",
apk: "Hail.apk",
privileged: true,
dex_preopt: {
enabled: false,
},
presigned: true,
preprocessed: true,
required: ["privapp-permissions_com.aistra.hail.xml"]
}
prebuilt_etc {
name: "privapp-permissions_com.aistra.hail.xml",
src: "privapp-permissions.xml",
sub_dir: "permissions",
}
```
## Revert
### By adb
Replace com.package.name to the package name of target app.
```shell
# Enable app
adb shell pm enable com.package.name
# Unhide app (root required)
adb shell su -c pm unhide com.package.name
# Unsuspend app
adb shell pm unsuspend com.package.name
```
### Modify file
Access `/data/system/users/0/package-restrictions.xml`, this file stores the restrictions about apps. You can modify, rename or just delete it.
- Enable app: Modify the value of `enabled` from 2 (DISABLED) or 3 (DISABLED_USER) to 1 (ENABLED)
- Unhide app: Modify the value of `hidden` from true to false
- Unsuspend app: Modify the value of `suspended` from true to false
### Wipe data by recovery
**None of my business :(**
## API
```shell
adb shell am start -a action -e key value
```
`action` can be one of the following constants:
- `com.aistra.hail.action.LAUNCH`: Unfreeze and launch target app. If it is unfrozen, it will launch directly. `key="package"` `value="com.package.name"`
- `com.aistra.hail.action.FREEZE`: Freeze target app. It must be checked at Home. `key="package"` `value="com.package.name"`
- `com.aistra.hail.action.UNFREEZE`: Unfreeze target app. `key="package"` `value="com.package.name"`
- `com.aistra.hail.action.FREEZE_TAG`: Freeze all non-whitelisted apps in the target tag. `key="tag"` `value="Tag name"`
- `com.aistra.hail.action.UNFREEZE_TAG`: Unfreeze all apps in the target tag. `key="tag"` `value="Tag name"`
- `com.aistra.hail.action.FREEZE_ALL`: Freeze all apps at Home. `extra` is not necessary.
- `com.aistra.hail.action.UNFREEZE_ALL`: Unfreeze all apps at Home. `extra` is not necessary.
- `com.aistra.hail.action.FREEZE_NON_WHITELISTED`: Freeze all non-whitelisted apps at Home. `extra` is not necessary.
- `com.aistra.hail.action.FREEZE_AUTO`: Auto freeze apps at Home. `extra` is not necessary.
- `com.aistra.hail.action.LOCK`: Lock screen. `extra` is not necessary.
- `com.aistra.hail.action.LOCK_FREEZE`: Freeze all apps at Home and lock screen. `extra` is not necessary.
