At the moment i'm trying to save a response to the internal storage in the phone. Everything works fine up until i try and retrieve the data again. When i log out the retrieved data it only logs out one small section of the response and the rest isn't there. Ive tried deleting the file and calling it again just incase it was using an old one.
Saving Code
try {
String response = apiResponse.getRawResponse();
Log.e("Response", response);
FileOutputStream userInfo = openFileOutput("personal_profile", MODE_PRIVATE);
userInfo.write(response.getBytes());
userInfo.close();
} catch (Exception e) {
e.printStackTrace();
Retrieving Code
String response = "";
try {
FileInputStream fis = getActivity().openFileInput("personal_profile");
DataInputStream isr = new DataInputStream(fis);
BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(isr));
StringBuilder sb = new StringBuilder();
String line;
while ((line = bufferedReader.readLine()) != null) {
sb.append(line);
}
line = response;
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
Log.e("Saved File", response);
Any kind of suggestions would be great!
REASON
The problem was that the line variable is assigned again in every iteration
Try this:
String response = "";
try {
FileInputStream fis = getActivity().openFileInput("personal_profile");
DataInputStream isr = new DataInputStream(fis);
BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(isr));
StringBuilder sb = new StringBuilder();
String line;
while ((line = bufferedReader.readLine()) != null) {
sb.append(line);
}
line = response;
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
CHANGE LAST LINE
Log.e("Saved File", sb.toString());
Have you got this in your AndroidManifest.xml file?
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
Also, this link has everything you need to know about reading and writing files:
http://www.anddev.org/working_with_files-t115.html
Code::
String response = "";
try {
FileInputStream fis = getActivity().openFileInput("personal_profile");
DataInputStream isr = new DataInputStream(fis);
BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(isr));
StringBuilder sb = new StringBuilder();
String line;
while ((line = bufferedReader.readLine()) != null) {
sb.append(line);
}
line = response;
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
Log.e("Saved File", sb.toString());

I'm new to using the Checkmarx tool and just checking for security flaws in code in general. I have a method which is supposed to read from an input stream. The method works, however I am getting XXE and SSRF errors.
public static String getStringFromInputStream(InputStream is) {
BufferedReader br = null;
StringBuilder sb = new StringBuilder();
String line;
try {
br = new BufferedReader(new InputStreamReader(is));
while ((line = br.readLine()) != null) {
sb.append(Normalizer.normalize(line, Normalizer.Form.NFD));
}
} catch (IOException e) {
LOG.error(
"********************",
e);
} finally {
if (br != null) {
try {
br.close();
} catch (IOException e) {
LOG.error(
******************,
e);
}
}
}
return sb.toString();
}
Below I have the following code to read in a file and go through it line by line.. This is using java's BufferedReader class. That I am fine with.
String filename = "C:\\test.txt"
String line = null;
FileReader fileReader = new FileReader(filename);
BufferedReader bufferedReader = new BufferedReader(fileReader);
try {
while (((line = bufferedReader.readLine()) != null)) {
//do the following....
}
} catch (IOException) {
e.printStackTrace();
}
However I want to now start using InputStreamReader in Spring / Java. I have the below code written but I am unsure how I can step through my file line by line. Really confused over this part. Anyone have any ideas or know how this can be done?
String filepath= "C:\\test.txt"
File filename= new File(filepath);
try {
InputStream fileInputStream = new BOMInputStream(new fileInputStream(filename));
// now want to step through the file, line by line..
} catch (IOException) {
e.printStackTrace();
}
Thanks
This is how you can read your input file byte by byte using InputStreamReader.
char[] chars = new char[100];
try {
InputStream inputStream = new FileInputStream("C:\\test.txt");
InputStreamReader inputStreamReader = new InputStreamReader(inputStream,"UTF-8");
inputStreamReader.read(chars);
System.out.println(new String(chars).trim());
} catch (IOException e) {
e.printStackTrace();
}
Check this out -
String filename = "C:\\test.txt"
String line = null;
FileInputStream fileInputStream = new FileInputStream(filename);
BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(fileInputStream));
try {
while (((line = bufferedReader.readLine()) != null)) {
//do the following....
}
} catch (IOException) {
e.printStackTrace();
}
public static void main(String[] args) {
try (BufferedReader reader = new BufferedReader(new InputStreamReader(new FileInputStream("c:\\test.txt")))) {
reader.lines().forEach(line -> {
// do what you want with the line
});
} catch (IOException e) {
throw new RuntimeException(e);
}
}
I have a simple text viewer class that opens text file and reads the strings. But the problem is, when the file is large >0.5Mb, opening takes quite a while. Is there a way to load small part first and then load all others or any other way to make this process faster ? Here is my code:
InputStream inputStream = null;
String str = "";
StringBuffer buf = new StringBuffer();
TextView txt = (TextView)findViewById(R.id.textView);
try {
inputStream = getContentResolver().openInputStream(uri);
} catch (FileNotFoundException e) {
e.printStackTrace();
}
BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));
if (inputStream!=null) {
try {
while ((str = reader.readLine()) != null) {
buf.append(str + "\n");
}
} catch (IOException e) {
e.printStackTrace();
}
try {
inputStream.close();
} catch (IOException e) {
e.printStackTrace();
}
txt.setText(buf.toString());
}
}
I want to read the text from a text file. In the code below, an exception occurs (that means it goes to the catch block). I put the text file in the application folder. Where should I put this text file (mani.txt) in order to read it correctly?
try
{
InputStream instream = openFileInput("E:\\test\\src\\com\\test\\mani.txt");
if (instream != null)
{
InputStreamReader inputreader = new InputStreamReader(instream);
BufferedReader buffreader = new BufferedReader(inputreader);
String line,line1 = "";
try
{
while ((line = buffreader.readLine()) != null)
line1+=line;
}catch (Exception e)
{
e.printStackTrace();
}
}
}
catch (Exception e)
{
String error="";
error=e.getMessage();
}
Try this :
I assume your text file is on sd card
//Find the directory for the SD Card using the API
//*Don't* hardcode "/sdcard"
File sdcard = Environment.getExternalStorageDirectory();
//Get the text file
File file = new File(sdcard,"file.txt");
//Read text from file
StringBuilder text = new StringBuilder();
try {
BufferedReader br = new BufferedReader(new FileReader(file));
String line;
while ((line = br.readLine()) != null) {
text.append(line);
text.append('\n');
}
br.close();
}
catch (IOException e) {
//You'll need to add proper error handling here
}
//Find the view by its id
TextView tv = (TextView)findViewById(R.id.text_view);
//Set the text
tv.setText(text.toString());

If you want to read file from sd card. Then following code might be helpful for you.
StringBuilder text = new StringBuilder();
try {
File sdcard = Environment.getExternalStorageDirectory();
File file = new File(sdcard,"testFile.txt");
BufferedReader br = new BufferedReader(new FileReader(file));
String line;
while ((line = br.readLine()) != null) {
text.append(line);
Log.i("Test", "text : "+text+" : end");
text.append('\n');
} }
catch (IOException e) {
e.printStackTrace();
}
finally{
br.close();
}
TextView tv = (TextView)findViewById(R.id.amount);
tv.setText(text.toString()); ////Set the text to text view.
}
}
If you wan to read file from asset folder then
AssetManager am = context.getAssets();
InputStream is = am.open("test.txt");
Or If you wan to read this file from res/raw foldery, where the file will be indexed and is accessible by an id in the R file:
InputStream is = getResources().openRawResource(R.raw.test);
Good example of reading text file from res/raw folder
Put your text file in Asset Folder...& read file form that folder...
see below reference links...

Reading a simple text file
hope it will help...
Try this code
public static String pathRoot = "/sdcard/system/temp/";
public static String readFromFile(Context contect, String nameFile) {
String aBuffer = "";
try {
File myFile = new File(pathRoot + nameFile);
FileInputStream fIn = new FileInputStream(myFile);
BufferedReader myReader = new BufferedReader(new InputStreamReader(fIn));
String aDataRow = "";
while ((aDataRow = myReader.readLine()) != null) {
aBuffer += aDataRow;
}
myReader.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return aBuffer;
}
First you store your text file in to raw folder.
private void loadWords() throws IOException {
Log.d(TAG, "Loading words...");
final Resources resources = mHelperContext.getResources();
InputStream inputStream = resources.openRawResource(R.raw.definitions);
BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));
try {
String line;
while ((line = reader.readLine()) != null) {
String[] strings = TextUtils.split(line, "-");
if (strings.length < 2)
continue;
long id = addWord(strings[0].trim(), strings[1].trim());
if (id < 0) {
Log.e(TAG, "unable to add word: " + strings[0].trim());
}
}
} finally {
reader.close();
}
Log.d(TAG, "DONE loading words.");
}
Shortest form for small text files (in Kotlin):
val reader = FileReader(path)
val txt = reader.readText()
reader.close()
Try this
try {
reader = new BufferedReader(new InputStreamReader(in,"UTF-8"));
} catch (UnsupportedEncodingException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
String line="";
String s ="";
try
{
line = reader.readLine();
}
catch (IOException e)
{
e.printStackTrace();
}
while (line != null)
{
s = s + line;
s =s+"\n";
try
{
line = reader.readLine();
}
catch (IOException e)
{
e.printStackTrace();
}
}
tv.setText(""+s);
}
Hey I have the following code:

dis = new DataInputStream(yahoo.openStream());
while ((inputLine = dis.readLine()) != null) {
System.out.println(inputLine);
}
dis.close();

How can i save the source code i get from this to a XML file? Please help
Create a Connection:
DefaultHttpClient httpclient = new DefaultHttpClient();
HttpGet httppost = new HttpGet("http://www.google.com");
HttpResponse response = httpclient.execute(httppost);
HttpEntity ht = response.getEntity();
BufferedHttpEntity buf = new BufferedHttpEntity(ht);
InputStream is = buf.getContent();
Put inputstream in a buffer and read it:
BufferedReader r = new BufferedReader(new InputStreamReader(is2));
total = new StringBuilder();
String line;
while ((line = r.readLine()) != null) {
total.append(line);
}
Then put it in the file:
File file = new File("/sdcard", "report.xml");
if(!file.exists()){
file.createNewFile();
}
StringBuilder temp = null;
while ((inputLine = dis.readLine()) != null) {
temp.append(inputLine);
}
FileWriter fw = new FileWriter(file);
fw.write(temp.toString());
fw.flush();
Hope this helpes
Here is an example, where "iso" is you InputSrteam
try {
final File file = new File("/sdcard/filename.xml");
final OutputStream output = new FileOutputStream(file);
try {
try {
final byte[] buffer = new byte[1024];
int read;
while ((read = iso.read(buffer)) != -1)
output.write(buffer, 0, read);
output.flush();
}
finally {
output.close();
}
} catch (Exception e) {
e.printStackTrace();
}
}
catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} finally {
try {
iso.close();
System.out.println("saved");
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
