Android WiFi ADB

Is it annoying to debug your app often by plugging in and out of USB? The charging port of your phone can be damaged easily after a long time. Use this plug-in to debug your app over WiFi. The method is very simple, the steps are as follows:

  1. First, make sure your computer and phone are on the same wifi LAN

  2. For the first time, connect the cable to your computer and make sure your device is visible to Android Monitors. The diagram below:

  3. Open the Android WiFi ADB panel and clickConnectAfter the button, you can unplug the data line.

    When the data cable is unplugged, “No devices Connected” is displayed in the “Android WiFi ADB” panel, but our device will still be displayed in the “Android Monitors”. All subsequent operations will be the same as when we connected the data cable.

What is Instant Run?

Instant Run is a feature of Android Studio 2.0, and with this feature, Android Studio has made a quantum leap in the speed at which applications can be compiled.

  • Previous Compilation process

  • Compilation process after 2.0

Since 2.0, Android Studio has selectively used hot Swap, Warm Swap, code Swap and other compilation schemes to speed up compilation.

After running the application for the first time, there is a lightning bolt next to the running triangle, indicating that Instant Run is now ready to use.

hot swap

Just change the internal code or instructions of the method, Android Studio will adopt the Hot Swap solution, the whole compilation and deployment is very fast.

Note: The default Hot Swap mode will also restart Activey, you need to go to the Settings, as shown below:

warm swap

In the case of modifying or deleting resources, Android Studio will adopt a warm swap scheme and you can see Activey being restructured.

cold swap

The whole process of Cold Swap took a little longer. Android Studio automatically recorded every change we made to our project and uploaded the change to the phone as a dex. The entire app was then restarted and the new dex was reloaded.
