How to create and write data a text file in android programatically? [duplicate]

Question

I am creating a sample application in my android phone to create a new text file and write some data on to that text file.

Same like java. Just you have to mention where to keep that file. e.g. Environment.getExternalStorageDirectory()+"/text/" — Kush Patel

Use these code you can write a text file in SDCard along with you need to set permission in android manifest

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

for device having os >= LOLIPOP you need to ask permissions runtime, this is the code :

public void generateNoteOnSD(Context context, String sFileName, String sBody) { try { File root = new File(Environment.getExternalStorageDirectory(), "Notes"); if (!root.exists()) { root.mkdirs(); } File gpxfile = new File(root, sFileName); FileWriter writer = new FileWriter(gpxfile); writer.append(sBody); writer.flush(); writer.close(); Toast.makeText(context, "Saved", Toast.LENGTH_SHORT).show(); } catch (IOException e) { e.printStackTrace(); } }
