Command Line Interface and APIs for Surelock

Applies to:
Product SureLock
Platform Android

Surelock uses a BroadcastReceiver to allow 3rd party applications to send specific commands to SureLock. Command can be send using Intent. (See examples below). To execute any command Administrator password is necessary.

Currently SureLock supports the following commands:

exit_surelock - This command exits the device from lock down mode.

public synchronized void exitSurelock()


/* Intent Action MUST be 'com.gears42.surelock.COMMUNICATOR' */

final Intent intent = new Intent("com.gears42.surelock.COMMUNICATOR");

/* the command to execute is 'exit_surelock' */

intent.putExtra("command", "exit_surelock");

/* optional parameter to identify the sender application */

intent.putExtra("sender", "com.gears42.test.kill_surelock");

/* SureLock's password. Command will NOT execute if password mismatches */

intent.putExtra("password", editText.getText().toString());



apply_settings - Apply SureLock settings using XML data.

final Intent intent = new Intent("com.gears42.surelock.COMMUNICATOR");

intent.putExtra("command", "apply_settings");

intent.putExtra("sender", context.getPackageName()); // optional intent.putExtra("password", surelockPassword);

intent.putExtra("setting_xml", surelockSettingFileContents);


change_password - Change SureLock password required to enter into Admin Settings.

final Intent intent = new Intent("com.gears42.surelock.COMMUNICATOR");

intent.putExtra("command", " change_password ");

intent.putExtra("sender", context.getPackageName()); // optional

intent.putExtra("password", surelockPassword);

intent.putExtra("new_password", newSureLockPassword);



final Intent intent = new Intent("com.gears42.surelock.COMMUNICATOR");

intent.putExtra("command", " force_apply_settings ");

intent.putExtra("sender", context.getPackageName()); // optional

intent.putExtra("password", surelockPassword);

intent.putExtra("settings_path", pathToSurelockSettingsFile);



You can also send SureLock commands from Command Line Interface:


To password change -

adb shell am broadcast -a com.gears42.surelock.COMMUNICATOR -e "command" "change_password" -e "password" "0000" -e "new_password" ""

To exit SureLock -

am broadcast -a com.gears42.surelock.COMMUNICATOR -e password 0000 -e command exit_surelock

To force apply changes -

adb shell am broadcast -a com.gears42.surelock.COMMUNICATOR -e "command" "force_apply_settings" -e "password" "0000" -e "settings_path" "/sdcard/SureLock.settings"

The challenges of aggregating data from consumer-oriented devices, such as wearable technologies and smart thermostats, are fairly well-understood.

Cell networks have the advantage of long-range communications, reaching an estimated 90% of the world. But cell networks such as 2G, 3G and LTE consume lots of power and were designed for connecting people.

Cell IoT modules that support narrow-band IoT and 4G cell networks will enable cell connectivity, device management, and app enablement for low-power wide-area network IoT. B...

When talking IoT we often focus on the devices, the sensors, the hardware itself. The new smart appliances, the new smart or self-driving cars (which are amalgamations of many ‘things'). When we are looking at the world of IoT, we should take a step back, look at the big picture. What value are these devices providing. IoT is not about the devices, its about the data consumed and generated. The devices are tools, mechanisms, conduits. This paper discusses the considerations when dealing with the...
