Check if file exists on Android SD card

Question

I want to check if a text file exists on the SD card. The file name is mytextfile.txt. Below is the code:

FileOutputStream fos = openFileOutput("sdcard/mytextfile.txt", MODE_WORLD_WRITEABLE); 

How to check if this file exists?

Answer 1

This should do the trick, I replaced the hardcode link SDcard with the recommended API call getExternalCacheDir () :

 File file = new File(getExternalCacheDir(), "mytextfile.txt" ); if (file.exists()) { //Do action } 

Answer 2

See this file System in android: Working with the SDCards file system in Android

you just check

 if(file.exists()){ // } 

Answer 3

* With this you can check whether a file exists or not in sdcard *

 File file = new File(sdcardpath+ "/" + filename); if (file.exists()) { } 

Answer 4

You need to create a file and install it as the necessary file and check if it exists.

 String FILENAME="mytextfile.txt"; File fileToCheck = new File(getExternalCacheDirectory(), FILENAME); if (fileToCheck.exists()) { FileOutputStream fos = openFileOutput("sdcard/mytextfile.txt", MODE_WORLD_WRITEABLE); } 

Good luck

Answer 5

The FileOutputStream constructor FileOutputStream exception if the specified file does not exist. See the Oracle documentation for more information.

Also, make sure you have permission to access the SD card .

Answer 6

check if condition with boolean type

 File file = new File(path+filename); if (file.exists() == true) { //Do something }
