Connecting to your test device
Repeato uses ADB (Android Debug Bridge) to communicate with your device.
To use ADB with a device connected over USB, you must enable USB debugging in the device system settings, under Developer options.
On Android 4.2 and higher, the Developer options screen is hidden by default. To make it visible, go to Settings > About phone and tap Build number seven times. Return to the previous screen to find Developer options at the bottom.
On some devices, the Developer options screen might be located or named differently.
When you connect a device running Android 4.2.2 or higher, the system shows a dialog asking whether to accept an RSA key that allows debugging through this computer. This security mechanism protects user devices because it ensures that USB debugging and other adb commands cannot be executed unless you're able to unlock the device and acknowledge the dialog.
