Now that we know how to properly save content to external storage, we will allow our users to save their text to their phone's internal storage, in order to protect it even more.. :)
If you have Termux:API application and termux-api package installed, you can use Android file picker to get any file from either shared or external storage by using utility termux-storage-get. Example: termux-storage-get filename.txt File that has been chosen through file picker will be saved as 'filename.txt'. When files are stored in internal storage these file can only be accessed by the application itself not by other applications. This is a reserved directory that Android uses for raw files that your app may need access to (i. How to Save a text file into the internal Storage of an android device.

Now I imagine that we will still need to ask the user’s permission to use their internal storage, right?
Actually, we don't! When you save information on the internal storage of your users’ phone, you do not need their permission since this space is allocated only to your app.. ;)
So in this chapter, we will allow our users to save their text (and consequently the file tripBook.txt) in the internal memory of their phone:
Updating the activity
Now let's get really serious! Since we created a rather general class utility in the previous chapter, StorageUtils, we’ll be reusing it here (but without editing it, obviously!).
Let’s update our activity in order to call the appropriate methods when the user clicks on the radio buttons dedicated to storage in internal memory.

Android Save File To Internal Storage Example
Explanations: We've added a method (1) dedicated to writing in our file in internal storage, which will be called by the
save method (3) when the user clicks on the 'Save' button on the Toolbar. We've also edited (2) the method readFromStorage in order to read the file from internal storage whenever the activity is run or when the user clicks on the radio buttons.
And what’s more, all this should remind you of something.. ;) Yes, we used the same approach to write and read to our external storage in the previous chapter, by calling the methods
getTextFromStorage and setTextInStorage , changing only the parameter corresponding to the root directory to match that of the internal storage:
Now run your app and try saving text in the internal storage space! :)
Note, you will not be able to see the two files created, simply because you do not have access as a user (unless your phone is rooted). That’s what internal storage is good for! ;)
Since this chapter is shorter, take the time to read and reread your code, in order to understand the logic behind it. And don't forget the golden rule of any good developer, Practice Makes Perfect! Good luck.. How to get snapchat on computer. :ange:
