On Android Studios. Open AVD Manager. Click Edit Icon to edit the AVD. Click Show Advanced settings. Change the Internal Storage, Ram, SD Card size as necessary. Confirm the popup by clicking yes. Wipe Data on the AVD and confirm the popup by clicking yes. Now start and use your Emulator with increased storage. To actually view the file open the Android Device Monitor from Tools-Android-Android Device Monitor. The file “mytextfile.txt” is found in the package name of the project i.e. Com.journaldev.internalstorage as shown below: Download the final project for android internal storage example from below link. When the app is uninstalled the data stored in the internal by that app is removed. To read and write in the android internal storage we have two methods. OpenFileOutput : used for creating and saving a file. This method returns a FileOutputStream instance. Syntax: OpenFileOutput (String filename,int mode).

Android provides many kinds of storage for applications to store their data. These storage places are shared preferences, internal and external storage, SQLite storage, and storage via network connection.
In this chapter we are going to look at the internal storage. Internal storage is the storage of the private data on the device memory.
By default these files are private and are accessed by only your application and get deleted , when user delete your application.
Writing file
In order to use internal storage to write some data in the file, call the openFileOutput() method with the name of the file and the mode. The mode could be private , public e.t.c. Its syntax is given below −
The method openFileOutput() returns an instance of FileOutputStream. So you receive it in the object of FileInputStream. After that you can call write method to write data on the file. Its syntax is given below −
Reading file
In order to read from the file you just created , call the openFileInput() method with the name of the file. It returns an instance of FileInputStream. Its syntax is given below −
Android Emulator Internal Storage Path App
After that, you can call read method to read one character at a time from the file and then you can print it. Its syntax is given below −
Apart from the the methods of write and close, there are other methods provided by the FileOutputStream class for better writing files. These methods are listed below −
Sr.No | Method & description |
---|---|
1 | FileOutputStream(File file, boolean append) This method constructs a new FileOutputStream that writes to file. |
2 | getChannel() This method returns a write-only FileChannel that shares its position with this stream |
3 | getFD() This method returns the underlying file descriptor |
4 | write(byte[] buffer, int byteOffset, int byteCount) This method Writes count bytes from the byte array buffer starting at position offset to this stream |
Apart from the the methods of read and close, there are other methods provided by the FileInputStream class for better reading files. These methods are listed below −
Sr.No | Method & description |
---|---|
1 | available() This method returns an estimated number of bytes that can be read or skipped without blocking for more input |
2 | getChannel() This method returns a read-only FileChannel that shares its position with this stream |
3 | getFD() This method returns the underlying file descriptor |
4 | read(byte[] buffer, int byteOffset, int byteCount) This method reads at most length bytes from this stream and stores them in the byte array b starting at offset |
Example
Here is an example demonstrating the use of internal storage to store and read files. It creates a basic storage application that allows you to read and write from internal storage.
To experiment with this example, you can run this on an actual device or in an emulator.
Steps | Description |
---|---|
1 | You will use Android Studio IDE to create an Android application under a package com.example.sairamkrishna.myapplication. |
2 | Modify src/MainActivity.java file to add necessary code. |
3 | Modify the res/layout/activity_main to add respective XML components |
4 | Run the application and choose a running android device and install the application on it and verify the results |
Following is the content of the modified main activity file src/MainActivity.java.
Following is the modified content of the xml res/layout/activity_main.xml.
In the following code abc indicates the logo of tutorialspoint.com
Following is the content of the res/values/string.xml.
Following is the content of AndroidManifest.xml file.
Let's try to run our Storage application we just modified. I assume you had created your AVD while doing environment setup. To run the app from Android studio, open one of your project's activity files and click Run icon from the tool bar. Android studio installs the app on your AVD and starts it and if everything is fine with your set-up and application, it will display following Emulator window −
Now what you need to do is to enter any text in the field. For example , i have entered some text. Press the save button. The following notification would appear in you AVD −
Now when you press the load button, the application will read the file , and display the data. In case of our, following data would be returned −
Note you can actually view this file by switching to DDMS tab. In DDMS , select file explorer and navigate this path.

By sd card, I am assuming that, you meant removable micro SD card.
In API level 19 i.e. in Android version 4.4 Kitkat, they have added File[] getExternalFilesDirs (String type)
in Context
Class that allows apps to store data/files in micro SD cards.
Android 4.4 is the first release of the platform that has actually allowed apps to use SD cards for storage. Any access to SD cards before API level 19 was through private, unsupported APIs.
Environment.getExternalStorageDirectory()
was there from API level 1
getExternalFilesDirs(String type) returns absolute paths to application-specific directories on all shared/external storage devices. It means, it will return paths to both internal and external memory. Generally, second returned path would be the storage path for microSD card (if any).
But note that,
Android Emulator Internal Storage Path Free
Shared storage may not always be available, since removable media can be ejected by the user. Media state can be checked using getExternalStorageState(File)
.
There is no security enforced with these files. For example, any application holding WRITE_EXTERNAL_STORAGE
can write to these files.

As some people indicated, the officially accepted answer does not quite return the external removable SD card. And i ran upon the following thread that proposes a method I've tested on some Android devices and seems to work reliably, so i thought of re-sharing here as i don't see it in the other responses:
Kudos to paresh996 for coming up with the answer itself, and i can attest I've tried on Samsung S7 and S7edge and seems to work.
Now, i needed a method that returned a valid path where to read files, and that considered the fact that there might not be an external SD, in which case the internal storage should be returned, so i modified the code from paresh996 to this :

- There is a buildin storage which is /storage/sdcard0 and an SD card which is /storage/sdcard1 in my phone( running android 4.1.2.) The Environment.getExternalStorageDirectory().getAbsolutePath() return /storage/sdcard0. Is there any way to get the path of SD card which is /storage/sdcard1? Hard code it?
- Environment.getExternalStorageDirectory() returns '/storage/emulated/0', while my SDCard actually lives at '/storage/extSdCard/'
- interesting answer, but you should, for completeness, include the class that your method getExternalFilesDirs exists in. dv for incompleteness.
- Nice workaround, are these all possible names for sd card?
- @SamvelKartashyan Sure not! :) For example, we had a device where the SD card was mounted on
'/storage/ext_sd/'
, and another where it is in '/mnt/sdcard/'
