How to Unlock Android Devices Before Appium Execution

Overview

This guide explains how to unlock Android devices before starting an Appium session to help avoid application installation failures caused by locked device screens.

Prerequisites

Before unlocking the device, ensure the following:

• ADB is installed and accessible.

• The Android device is connected successfully.

• Appium execution environment is configured.

Steps

Step 1: Unlock Android Device Before Appium Session

The issue may occur if the device screen is locked during the installation process.

To prevent this, unlock the device screen before the Appium session starts.

Java Example

1. Add the following method in your Java implementation:

public void unlockPixelScreen() throws IOException, InterruptedException {    // Wake up the device    Runtime.getRuntime().exec("adb shell input keyevent KEYCODE_WAKEUP");    Thread.sleep(1000);     // Unlock the screen (simulate swipe up/unlock key event)    Runtime.getRuntime().exec("adb shell input keyevent 82");    Thread.sleep(1000); }
