• Task type: Normal

---

Compatibility

• Minimum AndroMate version: 1.1.0

• Maximum AndroMate version: 1.1.0

• Minimum Android: Android 13 (API 33)

• Maximum Android tested: Android 16 (API 36)

• Required permissions: None

Detailed description

The Get Charging Type task reads the charger type from the Android battery broadcast (ACTION_BATTERY_CHANGED). The result indicates whether the device is connected via USB, an AC wall adapter, wireless charging, or is not connected to any charger. The result is stored as a string in value_output.

No special permissions are required — ACTION_BATTERY_CHANGED is a protected system broadcast available to all apps.

Input parameters

This task has no input parameters.

Output parameters

Field	Type	Trigger condition	Android Compatibility	AndroMate Compatibility	Default
value_output	String	Always on success — one of USB, AC, Wireless, None	Android 13 (API 33) → Android 16 (API 36)	1.1.0 → 1.1.0	<ANDROMATE_NULL_VALUE>

Possible output values

Value	Description
USB	Device is charging via a USB connection
AC	Device is charging via an AC wall adapter
Wireless	Device is charging wirelessly (Qi or similar)
None	No charger is connected

Special variables

When comparing the output of this task in a condition (e.g. Compare Strings), you can use the built-in AndroMate special variables instead of hardcoded strings. This avoids typos and keeps your workflow readable.

Special variable	Resolved value
${CHARGING_TYPE_USB}	"USB"
${CHARGING_TYPE_AC}	"AC"
${CHARGING_TYPE_WIRELESS}	"Wireless"
${CHARGING_TYPE_NONE}	"None"

Example — compare $charging_type against ${CHARGING_TYPE_AC} in a Compare Strings task instead of typing "AC" manually.

---

Exceptions

This task does not throw exceptions. If no charger is connected, "None" is stored in value_output.

    style Register fill:#fff9c4
    style ReadPlugged fill:#f3e5f5
    style StoreResult fill:#c8e6c9

How it works:

1. Register battery receiver: registers a one-shot receiver for ACTION_BATTERY_CHANGED
2. Read plugged state: extracts EXTRA_PLUGGED and maps the integer constant to a charger type string
3. Store result: sets value_output with the charger type string
4. Result: returns StrTaskResult

Output parameter details

value_output — Charger type

Stores the connected charger type as a string in the specified workflow variable.

• One of USB, AC, Wireless, None
• None means no charger is connected
• Tip: compare against the ${CHARGING_TYPE_*} special variables instead of hardcoded strings
