1- Android Device Monitor

Android Device Monitor is a tool to manage Android devices, it is a tool for the development of Android applications, can explore your Android device.

If you are a programmer, sometimes you needs to see the file system on the simulation device , copy the files in your simulation Android device to computer  and vice versa.
In this document I guide you to use the  "Android Device Monitor" tool.
Note: Android Device Monitor is a tool available on Android Studio versions older than 3.1. If you use Android Studio 3.1 or newer, use a similar tool, Device File Explorer.

There are several functional simulator is supported by "Android Device Monitor".

3.1- Create a message

Switch to "Emulator Control" TAB .

Here I simulate a phone number "01234567" to send messages to your simulation phone.
After clicking "Send" you will receive a message on the  simulation device. Same illustrated below:

3.2- Make a call

Assuming phone number 01234567  call to simulation device.
The simulation mobile has received calls.

4- Explore file system

Switch to the "File Explorer"  TAB,  you can see files and folders of simulation equipment.
The file system as you can see in the illustration below, it is a lot and confusing. However you need to pay attention to the  "storage"  folder  stored by the user.
See a snippet of code:

File dir = Environment.getExternalStorageDirectory();

if (!dir.exists()) {

// file:///storage/emulated/0/myvideo.mp4
String videoPath = dir.getAbsolutePath() + "/myvideo.mp4";
