I was trying to save text file using below code
try {
FileOutputStream fos = new FileOutputStream(TXT_FILE_NAME, true);
FileWriter fWriter;
try {
fWriter = new FileWriter(fos.getFD());
fWriter.write(binding.tvExtractedResult.getText().toString());
fWriter.close();
} catch (Exception e) {
e.printStackTrace();
} finally {
fos.getFD().sync();
fos.close();
Toast.makeText(this, "File Saved Successfully", Toast.LENGTH_LONG).show();
}
} catch (Exception e) {
Toast.makeText(this, "Error while saving file", Toast.LENGTH_LONG).show();
e.printStackTrace();
}
But the problem is this code doesn't work with Android Q.
After this I tried to search the solution and I did this
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
ContentValues myContentValues = new ContentValues();
myContentValues.put(MediaStore.MediaColumns.DISPLAY_NAME, TXT_FILE_NAME);
String myFolder = "Download/MY_PROJECT";
myContentValues.put(MediaStore.MediaColumns.RELATIVE_PATH, myFolder);
myContentValues.put(MediaStore.MediaColumns.MIME_TYPE, "text/plain");
myContentValues.put(MediaStore.MediaColumns.IS_PENDING, 1);
Uri extVolumeUri = MediaStore.Files.getContentUri(MediaStore.VOLUME_EXTERNAL);
ContentResolver contentResolver = getContentResolver();
Uri uri = contentResolver.insert(extVolumeUri, myContentValues);
if (uri == null) {
Log.e(TAG, "uri is null");
return;
}
Log.e(TAG, "uri=" + uri);
try {
FileOutputStream fos = new FileOutputStream(new File(uri.toString()));
fos.write(binding.tvExtractedResult.getText().toString().getBytes());
fos.close();
} catch (Exception e) {
Log.e(TAG, "error occurred" + e.getMessage());
e.printStackTrace();
} finally {
myContentValues.clear();
myContentValues.put(MediaStore.MediaColumns.IS_PENDING, 0);
contentResolver.update(uri, myContentValues, null, null);
}
}
In above code I'm getting uri == null
Appreciate your help.
Thanks.
Please have a look at this code, it will allow you to save text file below and higher versions of Android Q.
public static void saveFile(Context context, String fileName, String text, String extension) throws IOException{
OutputStream outputStream;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
ContentValues values = new ContentValues();
values.put(MediaStore.MediaColumns.DISPLAY_NAME, fileName + extension); // file name
values.put(MediaStore.MediaColumns.MIME_TYPE, "text/plain");
values.put(MediaStore.MediaColumns.RELATIVE_PATH, DIRECTORY);
Uri extVolumeUri = MediaStore.Files.getContentUri("external");
Uri fileUri = context.getContentResolver().insert(extVolumeUri, values);
outputStream = context.getContentResolver().openOutputStream(fileUri);
}
else {
String path = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOCUMENTS).toString() + FOLDER_NAME;
File file = new File(path, fileName + extension);
Log.d(TAG, "saveFile: file path - " + file.getAbsolutePath());
outputStream = new FileOutputStream(file);
}
byte[] bytes = text.getBytes();
outputStream.write(bytes);
outputStream.close();
}
The answer provided by #SheikhHasib is correct.
Here, however, is the Kotlin version of his code with small adjustments. This will save "backup.txt" file in the "Download" directory, and the file will contain "Example content". I've tested in on Android 11 and it works perfectly.
#Throws(IOException::class)
private fun saveFile(context: Context, fileName: String, text: String, extension: String) {
val outputStream: OutputStream? = if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
val values = ContentValues()
values.put(MediaStore.MediaColumns.DISPLAY_NAME, fileName)
values.put(MediaStore.MediaColumns.MIME_TYPE, "text/plain")
values.put(MediaStore.MediaColumns.RELATIVE_PATH, Environment.DIRECTORY_DOWNLOADS)
val extVolumeUri: Uri = MediaStore.Files.getContentUri("external")
val fileUri: Uri? = context.contentResolver.insert(extVolumeUri, values)
context.contentResolver.openOutputStream(fileUri!!)
} else {
val path = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS).toString()
val file = File(path, "$fileName.$extension")
FileOutputStream(file)
}
val bytes = text.toByteArray()
outputStream?.write(bytes)
outputStream?.close()
}
And to run it:
CoroutineScope(Dispatchers.IO).launch {
runCatching{
val content: String = "Example content"
saveFile(requireContext(), "backup", content, "txt")
}
}
when I upload my captured webveiw(bitmap image), I use this :
public static void saveBitmaptoPng(Bitmap bitmap, String folder, String name) {
String ex_storage = Environment.getExternalStorageDirectory().getAbsolutePath();
// Get Absolute Path in External Sdcard
String foler_name = "/" + folder + "/";
String file_name = name + ".png";
String string_path = ex_storage + foler_name;
File file_path;
try {
file_path = new File(string_path);
if (!file_path.isDirectory()) {
file_path.mkdirs();
}
FileOutputStream out = new FileOutputStream(string_path + file_name);
**bitmap.compress(Bitmap.CompressFormat.PNG, 90, out);**
out.close();
} catch (FileNotFoundException exception) {
Log.e("FileNotFoundException", exception.getMessage());
} catch (IOException exception) {
Log.e("IOException", exception.getMessage());
}
}
It is working well. but when I change 90 to 100 of Bitmap.CompressFormat,
I got an error whe getresponseCode
int serverResponseCode = connection.getResponseCode();
if (serverResponseCode == HttpURLConnection.HTTP_OK) {
is = new BufferedInputStream(connection.getInputStream());
} else {
is = new BufferedInputStream(connection.getErrorStream());
return null;
}
when changing from 90 to 100, process flow errorStream.... but I don't know any reasons.... even 95 is also not working well..
This code is running an apkfile after download from webserver.
But..
When the apkfile runs, it prints this message.
-Parse error
"There is a problem parsing the package."
When i run apkfile after copy to device, it did not print message.
How can I solve this ?

You probably need to flush the stream before closing it:
fos.flush();
fos.close();
Hi i have a string that contains html and css that i want to load into a WebView as a file. so i want to create a Directory on the internal storage i don't really want to store it on an SDCard as the file i'm saving contains important information. I then want to create a mFile.html not that directory. And the final step is then return the file to load into a WebView. Does anyone know how to do this?
heres what i have tried so far
public static void writeFileToDirectory(Context activityContext, String writableString,String folderName, String fileName){
File myDir = activityContext.getFilesDir();
try {
File secondFile = new File(myDir + "/" + folderName + "/", fileName);
if (secondFile.getParentFile().mkdirs()) {
secondFile.createNewFile();
FileOutputStream fos = new FileOutputStream(secondFile);
fos.write(writableString.getBytes());
fos.flush();
fos.close();
}
} catch (Exception e) {
e.printStackTrace();
}
try {
File secondInputFile = new File(myDir + "/html/", fileName);
InputStream secondInputStream = new BufferedInputStream(new FileInputStream(secondInputFile));
BufferedReader r = new BufferedReader(new InputStreamReader(secondInputStream));
StringBuilder total = new StringBuilder();
String line;
while ((line = r.readLine()) != null) {
total.append(line);
}
r.close();
secondInputStream.close();
Log.d("File", "File contents: " + total);
} catch (Exception e) {
e.printStackTrace();
}
try this
File myDir = activityContext.getFilesDir();
try {
File secondFile = new File(myDir + "/" + folderName);
if(!secondFile.exists())
{
secondFile.mkdir();
}
FileOutputStream fos = new FileOutputStream(secondFile.getAbsolutePath()+"/"+fileaName);
fos.write(writableString.getBytes());
fos.flush();
fos.close();
}
} catch (Exception e) {
e.printStackTrace();
}
I have a little issue with creating a directory and saving a file to it on my android application. I'm using this piece of code to do this :
String filename = "MyApp/MediaTag/MediaTag-"+objectId+".png";
File file = new File(Environment.getExternalStorageDirectory(), filename);
FileOutputStream fos;
fos = new FileOutputStream(file);
fos.write(mediaTagBuffer);
fos.flush();
fos.close();
But it's throwing an exception :
java.io.FileNotFoundException: /mnt/sdcard/MyApp/MediaCard/MediaCard-0.png (No such file or directory)
on that line : fos = new FileOutputStream(file);
If I set the filename to : "MyApp/MediaTag-"+objectId+" it's working, but If I try to create and save the file to an another directory it's throwing the exception. So any ideas what I'm doing wrong?
And another question: Is there any way to make my files private in external storage so user can't see them in gallery, only if he connect his device as Disk Drive?
Use this function to save your bitmap in SD card
private void SaveImage(Bitmap finalBitmap) {
String root = Environment.getExternalStorageDirectory().toString();
File myDir = new File(root + "/saved_images");
if (!myDir.exists()) {
myDir.mkdirs();
}
Random generator = new Random();
int n = 10000;
n = generator.nextInt(n);
String fname = "Image-"+ n +".jpg";
File file = new File (myDir, fname);
if (file.exists ())
file.delete ();
try {
FileOutputStream out = new FileOutputStream(file);
finalBitmap.compress(Bitmap.CompressFormat.JPEG, 90, out);
out.flush();
out.close();
} catch (Exception e) {
e.printStackTrace();
}
}
and add this in manifest
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
EDIT: By using this line you will be able to see saved images in the gallery view.
sendBroadcast(new Intent(Intent.ACTION_MEDIA_MOUNTED,
Uri.parse("file://" + Environment.getExternalStorageDirectory())));
look at this link also http://rajareddypolam.wordpress.com/?p=3&preview=true
The code presented by RajaReddy no longer works for KitKat
This one does (2 changes):
private void saveImageToExternalStorage(Bitmap finalBitmap) {
String root = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES).toString();
File myDir = new File(root + "/saved_images");
myDir.mkdirs();
Random generator = new Random();
int n = 10000;
n = generator.nextInt(n);
String fname = "Image-" + n + ".jpg";
File file = new File(myDir, fname);
if (file.exists())
file.delete();
try {
FileOutputStream out = new FileOutputStream(file);
finalBitmap.compress(Bitmap.CompressFormat.JPEG, 90, out);
out.flush();
out.close();
}
catch (Exception e) {
e.printStackTrace();
}
// Tell the media scanner about the new file so that it is
// immediately available to the user.
MediaScannerConnection.scanFile(this, new String[] { file.toString() }, null,
new MediaScannerConnection.OnScanCompletedListener() {
public void onScanCompleted(String path, Uri uri) {
Log.i("ExternalStorage", "Scanned " + path + ":");
Log.i("ExternalStorage", "-> uri=" + uri);
}
});
}
Update 2018, SDK >= 23.
Now you should also check if the user has granted permission to external storage by using:
public boolean isStoragePermissionGranted() {
String TAG = "Storage Permission";
if (Build.VERSION.SDK_INT >= 23) {
if (this.checkSelfPermission(android.Manifest.permission.WRITE_EXTERNAL_STORAGE)
== PackageManager.PERMISSION_GRANTED) {
Log.v(TAG, "Permission is granted");
return true;
} else {
Log.v(TAG, "Permission is revoked");
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, 1);
return false;
}
}
else { //permission is automatically granted on sdk<23 upon installation
Log.v(TAG,"Permission is granted");
return true;
}
}
public void saveImageBitmap(Bitmap image_bitmap, String image_name) {
String root = Environment.getExternalStorageDirectory().toString();
if (isStoragePermissionGranted()) { // check or ask permission
File myDir = new File(root, "/saved_images");
if (!myDir.exists()) {
myDir.mkdirs();
}
String fname = "Image-" + image_name + ".jpg";
File file = new File(myDir, fname);
if (file.exists()) {
file.delete();
}
try {
file.createNewFile(); // if file already exists will do nothing
FileOutputStream out = new FileOutputStream(file);
image_bitmap.compress(Bitmap.CompressFormat.JPEG, 90, out);
out.flush();
out.close();
} catch (Exception e) {
e.printStackTrace();
}
MediaScannerConnection.scanFile(this, new String[]{file.toString()}, new String[]{file.getName()}, null);
}
}
and of course, add in the AndroidManifest.xml:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
You need a permission for this
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
and method:
public boolean saveImageOnExternalData(String filePath, byte[] fileData) {
boolean isFileSaved = false;
try {
File f = new File(filePath);
if (f.exists())
f.delete();
f.createNewFile();
FileOutputStream fos = new FileOutputStream(f);
fos.write(fileData);
fos.flush();
fos.close();
isFileSaved = true;
// File Saved
} catch (FileNotFoundException e) {
System.out.println("FileNotFoundException");
e.printStackTrace();
} catch (IOException e) {
System.out.println("IOException");
e.printStackTrace();
}
return isFileSaved;
// File Not Saved
}
Make sure your app has the proper permissions to be allowed to write to external storage: http://developer.android.com/reference/android/Manifest.permission.html#WRITE_EXTERNAL_STORAGE
It should look something like this in your manifest file:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

Probably exception is thrown because there is no MediaCard subdir. You should check if all dirs in the path exist.
About visibility of your files: if you put file named .nomedia in your dir you are telling Android that you don't want it to scan it for media files and they will not appear in the gallery.
For API level 23 (Marshmallow) and later, additional to uses-permission in manifest, pop up permission should also be implemented, and user needs to grant it while using the app in run-time.
Below, there is an example to save hello world! as content of myFile.txt file in Test directory inside picture directory.
In the manifest:
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
Where you want to create the file:
int permission = ActivityCompat.checkSelfPermission(MainActivity.this, Manifest.permission.WRITE_EXTERNAL_STORAGE);
String[] PERMISSIONS_STORAGE = {Manifest.permission.READ_EXTERNAL_STORAGE, Manifest.permission.WRITE_EXTERNAL_STORAGE};
if (permission != PackageManager.PERMISSION_GRANTED)
{
ActivityCompat.requestPermissions(MainActivity.this,PERMISSIONS_STORAGE, 1);
}
File myDir = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES), "Test");
myDir.mkdirs();
try
{
String FILENAME = "myFile.txt";
File file = new File (myDir, FILENAME);
String string = "hello world!";
FileOutputStream fos = new FileOutputStream(file);
fos.write(string.getBytes());
fos.close();
}
catch (IOException e) {
e.printStackTrace();
}
Old way of saving files might not work with new versions of android, starting with android10.
fun saveMediaToStorage(bitmap: Bitmap) {
//Generating a dummy file name
val filename = "${System.currentTimeMillis()}.jpg"
//Output stream
var fos: OutputStream? = null
//For devices running android >= Q
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
//getting the contentResolver
context?.contentResolver?.also { resolver ->
//Content resolver will process the contentvalues
val contentValues = ContentValues().apply {
//putting file information in content values
put(MediaStore.MediaColumns.DISPLAY_NAME, filename)
put(MediaStore.MediaColumns.MIME_TYPE, "image/jpg")
put(MediaStore.MediaColumns.RELATIVE_PATH, Environment.DIRECTORY_PICTURES)
}
//Inserting the contentValues to contentResolver and getting the Uri
val imageUri: Uri? =
resolver.insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, contentValues)
//Opening an outputstream with the Uri that we got
fos = imageUri?.let { resolver.openOutputStream(it) }
}
} else {
//These for devices running on android < Q
//So I don't think an explanation is needed here
val imagesDir =
Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES)
val image = File(imagesDir, filename)
fos = FileOutputStream(image)
}
fos?.use {
//Finally writing the bitmap to the output stream that we opened
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, it)
context?.toast("Saved to Photos")
}
}
Reference- https://www.simplifiedcoding.net/android-save-bitmap-to-gallery/
since android 4.4 file saving has been changed. there is
ContextCompat.getExternalFilesDirs(context, name);
it retuns an array.
when name is null
the first value is like /storage/emulated/0/Android/com.my.package/files
the second value is like
/storage/extSdCard/Android/com.my.package/files
android 4.3 and less it retuns a single item array
parts of little messy code but it demonstrates how it works:
/** Create a File for saving an image or video

private File getOutputMediaFile(int type) throws Exception{
// Check that the SDCard is mounted
File mediaStorageDir;

}
// Create the storage directory(MyCameraVideo) if it does not exist
if (! mediaStorageDir.exists()){
if (! mediaStorageDir.mkdirs()){
output.setText("Failed to create directory.");
Toast.makeText(this, "Failed to create directory.", Toast.LENGTH_LONG).show();
Log.d("myapp", "Failed to create directory");
return null;
}
}
// Create a media file name

} else {
