The article explains why UIAutomator 1.0 scripts fail on the Android R emulator due to a missing android.test.RepetitiveTest class, analyzes the stack trace to locate the error in UiAutomatorTestRunner, and provides a workaround by manually initializing the test framework via app_process.
This article introduces Appium's basic element locating techniques—including id, name, class name, XPath, UIAutomator, and relative coordinates—explains how to handle non‑unique elements through iteration or OCR, and demonstrates image‑based locating with OpenCV and screenshot code examples.
This article demonstrates how to capture a video progress bar in an Android app with UiAutomator, extract its bitmap, analyze the red channel values, and compute the playback percentage for automated test assertions.
This article shows how to implement a post‑test reminder for UiAutomator by using screen sleep and wake‑up logic, providing Java code that checks the screen state, re‑activates it if needed, and optionally sets screen brightness via an ADB command.
The author shares a practical UiAutomator solution that captures screenshots, extracts bitmap data, and analyzes pixel colors to programmatically determine whether a UI element appears blue, including reusable helper methods for retrieving individual red, green, blue, or full RGB values.
This article explains how to automate the login process for multiple Android channel packages by packaging a Java UiAutomator script into a JAR, pushing it to the device, iterating over each APK, executing ADB commands, and logging success or failure for each login method.
This article presents a customizable Java helper class for Android UiAutomator that streamlines test project creation, build modification, APK deployment, and test execution, complete with detailed code, command explanations, and logging utilities for flexible mobile UI testing.
This guide shows how to create reusable UiAutomator helper methods that perform long‑press actions on Android UI elements—by resource ID, visible text, or explicit coordinates—using a swipe call with a 300‑step duration, and mentions extending the approach to custom gesture paths.
This article explains how to use UiAutomator scripts combined with Java multithreading to continuously refresh an Android app’s home page while capturing logs and performance metrics, including full code examples for command execution, timestamp handling, and test loops.
This article shares a comprehensive collection of reusable UiAutomator methods—including swipe gestures, screenshot handling, image analysis, UI element lookup, waiting strategies, click actions, scrolling, app launch/stop commands, and miscellaneous helpers—providing Android developers with ready‑to‑use Java code for robust UI automation testing.
This guide shows how to automatically change the Android input method to UTF‑7 or any other IME during UiAutomator tests by executing ADB commands, listing available IMEs, and handling command output on both macOS and Windows environments.
When using UiAutomator on macOS you must prepend the full path to the Android command and adjust slash handling, otherwise you encounter "Cannot run program" errors; this guide shows the errors, the required fixes, and provides a complete Java helper class for automated testing.
When UiAutomator reports controls with bounds [0,0][0,0] and they cannot be clicked, you can compute click positions from a previously‑found element’s size and use those coordinates to tap the left or right half of the target control.
This tutorial shows how to use the polar equation of a heart, convert mathematical coordinates to screen coordinates, and employ UiAutomator's swipe method to draw a heart shape on an Android device using Java.
The author encountered unexpected security‑warning pop‑ups during Android UIAutomator testing and created a UiWatcher that automatically clicks "Do not remind" and "Allow" to keep the test flow uninterrupted, sharing the full code for others to use.
This guide explains how to use Java's Runtime API within a UiAutomator test to start, filter, and safely terminate an adb logcat process, including a complete Logcat thread implementation and tips for preventing oversized log files.
The article demonstrates a simple Java ThreadTest class that enables concurrent database updates during Android UIAutomator and Selenium‑Java test cases, showing how to control execution with key flags, integrate the thread into test methods, and optionally use join() to avoid exceptions.
This article explains how to perform ordered UI traversal of an Android application with UIAutomator on the 360 Open Testing platform, covering required parameters, a seven‑step implementation process, UI change listening via AccessibilityService, element dumping, sorting, comparison methods, interaction automation, and termination conditions.
The article details how Baidu MTC designed and implemented a universal Android script testing platform that combines UIAutomator, a custom Clean‑SDK for popup handling, image‑recognition algorithms, and a recording‑playback tool to enable robust, non‑native mobile automated testing across thousands of devices.
This article introduces SmartMonkey, a custom Android testing solution that overcomes the randomness and inefficiency of the built‑in Monkey tool by using UIAutomator to parse UI hierarchies, select meaningful nodes, and execute controlled actions for more effective stability and functional testing.
This article describes how to employ UIAutomator to automate data extraction from K12 education mobile apps, handling device identity spoofing, image input normalization, and UI control reverse‑engineering to overcome encryption, token checks, and non‑standard input challenges.
