For automated testing 21 // labs and similar other uses, adbd contains a watchdog that can be enabled 22 // to reboot the device if no client is connected for a configurable duration. 23 // 24 // To enable it, set the system property `persist.adb.watchdog` to "1". 25 // The timeout can be configured by `persist.adb.watchdog.timeout_secs`, 26 // with a default of 600 seconds. 27 // 28 // Additionally, the watchdog is automatically enabled when the device is in 29 // test harness mode (https://source.android.com/compatibility/cts/harness). 30 // Note that if `persist.adb.watchdog` is set, it will override the default 31 // in test harness mode, and `persist.adb.watchdog.timeout_secs` isn't 32 // preserved across factory reset. 33 34 #if defined(__ANDROID__) 35 namespace watchdog { 36 37 void Initialize(); 38 void Start(); 39 void Stop(); 40 41 } // namespace watchdog 42 #endif 43
