Android: Write Text To Txt

With the following code, I try to write to my sdcard: public void writedata(String data) { //BufferedWriter out = null; System.out.println(data); try

Solution 1:

Try with this code:

File sdCard = Environment.getExternalStorageDirectory();
File dir = new File (sdCard.getAbsolutePath() + "/dir");

File file = new File(dir, "tsxt.txt");

FileOutputStream f = new FileOutputStream(file);

So the path to the file is not correct. You should remove directory name:

File dir = new File (sdCard.getAbsolutePath() + "/");

Solution 2:

Try this:

BufferedWriter out;         
try {

FileWriter fileWriter= new FileWriter(Environment.getExternalStorageDirectory().getPath()+"/tsxt.txt")

out = new BufferedWriter(fileWriter);

out.write("Your text to write");

out.close(); 

}catch (FileNotFoundException e) {
 e.printStackTrace();
}catch (IOException e) {
 e.printStackTrace();
}

Solution 3:

  try{
    File myFile = new File("/sdcard/tsxt.txt");
    myFile.createNewFile();
    FileOutputStream fOut = new FileOutputStream(myFile);
    OutputStreamWriter myOutWriter = new OutputStreamWriter(fOut);
    myOutWriter.append("your data here");
    myOutWriter.close();
    fOut.close();
}catch(Exception e){}

Solution 4:

Try this

 FileOutputStream fOut =openFileOutput(Environment.getExternalStorageDirectory().getPath()+"/tsxt.txt",MODE_WORLD_READABLE);
 OutputStreamWriter osw = new OutputStreamWriter(fOut);
//---write the string to the file---
 osw.write(str);
 osw.flush();
 osw.close();

Solution 5:

Before writing any file on sd card you need to check that is sdcard mounted or not, if not then just mount it and then write the file on it using external storage path.

you may use following code to check is sdcard mount or not

static public boolean hasStorage(boolean requireWriteAccess) {
    //TODO: After fix the bug,  add "if (VERBOSE)" before logging errors.
    String state = Environment.getExternalStorageState();
    Log.v(TAG, "storage state is " + state);

    if (Environment.MEDIA_MOUNTED.equals(state)) {
        if (requireWriteAccess) {
            boolean writable = checkFsWritable();
            Log.v(TAG, "storage writable is " + writable);
            return writable;
        } else {
            return true;
        }
    } else if (!requireWriteAccess && Environment.MEDIA_MOUNTED_READ_ONLY.equals(state)) {
        return true;
    }
    return false;
}

if(hasStorage(true)){

//call here your writedata() function



}
