EcoCtl (NW & SYNC control)

On Android 5.0 +, root authority is required.
On Android 6.0 +, it conflicts with Doze mode.

(Describe in notice from Google)
Ecoctl accesses android.permission.GET_ACCOUNTS to obtain synchronization account information. This information is used for synchronization control purposes. It is used only for display on the setting screen and saving settings.

1.
Automatically stop network (3G / LTE, WiFi selectable) when the screen turns off. Automatic restart by unlocking.
Since network is automatically restart periodically even when it is off, receive of e-mail etc. is also possible.
(Because network control is based on Android's security policy, it will not work on non-root Android 5.0 or later.)

2.
You can stop syncing in the battery mode. It will be back automatically by changing to the charge mode.
You can select the syncing items you want to stop in the battery mode.
For example, you can continue synchronization only GMail. (and stop the other synchronizations)

3.
EcoCtl itself consumes almost no battery.

・We have confirmed receipt of mail by Gmail, K - 9 Mail. Depending on the mailer, it may not be received successfully at the timing of network return.
・The network stop function is automatically disabled during tethering.

4.
You can change some settings with the shell command.
am startservice -n com.jp.ssipa.ecoctl/.MyService --es SERVICE_STATUS SET_SETTING --es SUB_STATUS {*1} --ez VALUEb {true|false}
*1
DATA_NW_CHECK Disable 3G/LTE in sleep mode.
WIFI_NW_CHECK Disable Wi-Fi in sleep mode.
BATTERY_NW_CHECK Keeping network connections ON while charging.
BATTERY_SYNC_CHECK SYNC on charging only.
WIFI_SYNC_CHECK SYNC on Wi-Fi only.

Example, Stop "disable 3G/LTE in sleep mode".
am startservice -n com.jp.ssipa.ecoctl/.MyService --es SERVICE_STATUS SET_SETTING --es SUB_STATUS DATA_NW_CHECK --ez VALUEb false
