How To Read From The Internal Storage (subfolder Download)?

After intensive search I could not find out how to read a configuration file (xml) from the internal storage (sub-folder download). I tried to access /mnt/sdcard/Download/config.xm

Solution 1:

1. Set the Read-Permission in your AndroidManifest.xml:

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

2. Use the following code:

   Stringfilename= Environment.getExternalStorageDirectory().getPath() + File.separator + "download" + File.separator + "config.xml";
   

3. Use filename for whatever you want to do.

Solution 2:

You may try following code when you face a condition to read a file from a subfolder in internal storage. Sometimes you may get problems with openFileInput whey you trying to passing context. here is the function.

publicStringgetDataFromFile(File file){  
     StringBuilder data= newStringBuilder();  
    try {
        BufferedReader br = newBufferedReader(newFileReader(file));
        String singleLine;
        while ((singleLine= br.readLine()) != null) {
            data.append(singleLine);
            data.append('\n');
        }
        br.close();
        return data.toString();
    }
    catch (IOException e) {
        return""+e;
    }
}
