This tool on every surface: CLI · MCP · Python · JavaScript · Go · Java · .NET

Read or set the device's network conditions: offline, latency and bandwidth. These call app_network.

network​

public Map<String, Object> network()

The network: airplane, online, and the shaping — latency_ms, download_kbps, upload_kbps, zero for none. Android only.

@return the network, read from the device

setOffline​

public Map<String, Object> setOffline(boolean offline)

Turns airplane mode on or off and waits for the network to follow — on an emulator or a real Android phone.

@param offline true for airplane mode @return the network, read back

shapeNetwork​

public Map<String, Object> shapeNetwork(int latencyMs, int downloadKbps, int uploadKbps)

Adds latency to each round trip and limits download and upload, in kbit/s, replacing any shaping set before; zero is none. Needs root, so an emulator.

@param latencyMs milliseconds added to each round trip @param downloadKbps the download limit @param uploadKbps the upload limit @return the network, read back

resetNetwork​

public Map<String, Object> resetNetwork()

Removes the shaping and turns airplane mode off.

@return the network, read back

Examples​

Go offline​

Map<String, Object> network = device.setOffline(true);   // read back once airplane mode holds

The same call from the command line, mobium network --offline, printed on an Android 15 emulator:

mobium network --offline on an Android 15 emulator

A slow connection, on an emulator​

device.shapeNetwork(300, 500, 0);   // 0: no upload limit

The same call from the command line, mobium network --latency 300 --download 500, printed on an Android 15 emulator:

online; 300ms added to each round trip, download 500 kbit/s
