Android: how to read html files from internal storage and load in webview

Question

i've searched alot but nothing solves my problem. i want to build an app which reads html files from tab's internal folder. the path of html files is /file manager/device storage/Android/data/K1.html.
The problem is that the number of web pages may increase or decrease by user and i want to build the functionality that app can read all the webpages placed in that folder. i used following code for reading file from internal storage but it doesn't point to the path. I know it is not difficult please guide me how to obtain this functionality, thanks in advance.

File tabFolder = getFilesDir();
String root = tabFolder.toString();
File myFile = new File(root + "/Android/data/K1.html");
    if(myFile.exists()){
    Toast.makeText(MainActivity.this, "exists", Toast.LENGTH_SHORT).show();

    }
    else{
        Toast.makeText(MainActivity.this, "does not exists", Toast.LENGTH_SHORT).show();
    }

yes i used this permission but it for external storage is there any other permission for internal storage? — konain ali, Feb 26 '15 at 05:52

try now...

String fileName = "K1.html";
String content = "K1 html file content here";
FileOutputStream outputStream = null;
try {
outputStream = openFileOutput(fileName, Context.MODE_PRIVATE);
outputStream.write(content.getBytes());
outputStream.close();
} catch (Exception e) {
e.printStackTrace();}

String path=getApplicationContext().getFilesDir().getAbsolutePath()+"/K1.html";
File file = new File ( path ); 
if ( file.exists() ) 
{
 // Toast File is exists
}
else
{
 // Toast File is not exists
}

getAbsolutePath points to this path /data/data/com.example.html/files/K1.html and the 'files' folder is empty, that is why it does not read the file because k1.html does not exist in this path.. could you please suggest me how to place file in this folder, i tried but i'm unable to paste K1.html here. – konain ali Feb 26 '15 at 07:21
