Of course the proof of the pudding is that it should run on actual devices, andĮmulators do a fairly good job but not a perfect one of simulating actualĭevices, so ultimately you want to test on real devices. That your program performs robustly across the variety of platforms on which it This is extremely useful in being certain You can configure many different virtual devices having differentĬharacteristics (for example, running different versions of Android with variousĪsumptions about SD card size, size of the screen, available input devices, For example, when I first started programming Android I developed apps for a number of months before I was able to obtain an Android phone.
You don't have to have actual hardware running Android to begin developing Testing with Android Virtual Devices (AVD) has Simulate various actual Android devices on your development computer. That, but for rapid development it is very useful to configure In Installing on a Device we will see how to do Programs can be installed and tested directly on an Android device through a USB connectionīetween the development computer and the device.
