Point to source code and set breakpoints. Output in the cf264b8f andemulator-5554 is serialNumber. Such as: adb devices List of devices attached cf264b8f device emulator-5554 device.
The emulator and process should be listed. In the case of multiple devices / simulators are connected to the more common -sA daemon, which runs as a background process on each emulator or device instance.
In Android Studio menu options, select Run->Attach debugger. The server manages communication between the client and the adb daemon running on an emulator or device. You will need to re-run the set debug each time (or use -persistent option). You will get a popup that the app is waiting for a debug to attach. Run adb shell am set-debug-app -w .samples.masterdetail. Set the app to debug at startup (note the -w) Debug with ADB commandsįollow these steps to debug using ADB commands: You can also simulate app spanning and other gestures as part of UI Testing. When the server has set up associations with all devices, you can utilize ADB commands to link to those gadgets. For example: emulator Nexus5XAPI23 -cache /.android/avd/Nexus5XAPI23.avd/cachepersistent.img -cache-size size: Set the cache partition size in MBs. For more information, see AVD data directory.
If you don't use this option, the default is a temporary file named cache.img. The time is important because if you drag too fast, the app is “flung” to the other screen rather than spanned. etc thus, the emulator native to ADB on port 5555 is identical to the emulator whose base tunes in on port 5554. If the file doesn't exist, the emulator creates it as an empty file. The first four values are the start and end coordinates of the drag gesture, and the final value is elapsed time (milliseconds).
You can simulate this gesture with ADB, using the following command: adb shell input touchscreen swipe 675 1780 1350 1500 3000 These screenshots illustrate the process of spanning by grabbing the handle at the bottom of the window, and dragging it towards the hinge until the span indicator covers both screens:
