I was wondering if it was possible to specifically determine if an Android device was plugged into a computer or just power.

The main reason is I\'d like for my phon

Answer 1

I actually found the exact way to choose whether to keep the screen on when plugged into AC, USB or either by looking into the source at http://google.com/codesearch#409TP6F96yI/src/com/android/settings/DevelopmentSettings.java&l=95

Requires permission: android.permission.WRITE_SETTINGS

Settings.System.putInt(getContentResolver(), Settings.System.STAY_ON_WHILE_PLUGGED_IN,
                mKeepScreenOn.isChecked() ?
                (BatteryManager.BATTERY_PLUGGED_AC | BatteryManager.BATTERY_PLUGGED_USB) : 0);

For AC: BatteryManager.BATTERY_PLUGGED_AC

For USB: BatteryManager.BATTERY_PLUGGED_USB

For Either: (BatteryManager.BATTERY_PLUGGED_AC | BatteryManager.BATTERY_PLUGGED_USB)
