I need to pick PDf file instead if the image

public void getPhoto() {
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("file/*");
startActivityForResult(intent, 1);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 1 && resultCode == RESULT_OK && data != null) {
Uri selectedImage = data.getData();
try {
if(clicked==true){
Bitmap bitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), selectedImage);
Log.i("Photo", "Received");
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.PNG, 100, stream);
byte[] byteArray = stream.toByteArray();
ParseFile file = new ParseFile("image.png", byteArray);
}
I'm struggling to sort out this problem somebody tell how to get pdf file and convert into Byte array

use this code to get pick pdf file and get the name, path, file, and Byte[];
public void getPhoto() {
Intent intent = new Intent();
intent.setAction(Intent.ACTION_GET_CONTENT);
intent.setType("application/pdf");
startActivityForResult(intent, 1);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 1 && resultCode == RESULT_OK && data != null) {
Uri selectedImage = data.getData();
try {
if(clicked==true){
Uri uri = data.getData();
String uriString = uri.toString();
File myFile = new File(uriString);
String path = myFile.getAbsolutePath();
String displayName = null;
Byte[] fileToByteArray=org.apache.commons.io.FileUtils.readFileToByteArray(myFile);
if (uriString.startsWith("content://")) {
Cursor cursor = null;
try {
cursor = getActivity().getContentResolver().query(uri, null, null, null, null);
if (cursor != null && cursor.moveToFirst()) {
displayName = cursor.getString(cursor.getColumnIndex(OpenableColumns.DISPLAY_NAME));
}
} finally {
cursor.close();
}
} else if (uriString.startsWith("file://")) {
displayName = myFile.getName();
}
}

Use below code and declare provider in your manifest.xml. and also create a provider.xml in your xml folder and provide the desired path in provider.xml and use the byte array for following code.
File pdf = new File(Environment.getExternalStorageDirectory(), "Download" +"/"+ fileName+ ".pdf");
Uri fileURI = FileProvider.getUriForFile(MainActivity.this, "your package name" + ".provider", file1);
Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
intent.setDataAndType(fileURI, "application/pdf");
intent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION | Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);

Path of selected image is null

I am trying to get the real path of a URI.
First I start the gallery app through an intent:
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, "Select picture"), SELECT_IMAGE );
After that the onActivityResult gets called, where I try to get the absolut path of the URI.
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
try {
if (resultCode == RESULT_OK) {
Uri uri;
if (requestCode == SELECT_IMAGE) {
final Uri uri_data = data.getData();
// Get the path from the Uri
final String path = getPathFromURI(uri_data);
if (path != null) {
File f = new File(path);
uri = Uri.fromFile(f);
}
}
}
} catch (Exception e) {
Log.e("FileSelectorActivity", "File select error", e);
}
}
The uri_data contains "content://com.android.providers.media.documents/document/image%3A67", but the resulting path is null.
The pathFromUri method looks like this:
private String getPathFromURI(Uri contentUri) {
String res = null;
String[] proj = {MediaStore.Images.Media.DATA};
Cursor cursor = getContentResolver().query(contentUri, proj, null, null, null);
if (cursor.moveToFirst()) {
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
res = cursor.getString(column_index);
}
cursor.close();
return res;
}
Here the column_index is 0, but cursor.getString returns null.
Why does this happen?
I have the permission android.permission.READ_EXTERNAL_STORAGE
EDIT:
So I want to take a picture through the camera app, and the user then chooses the image. So the file should be acutally stored on the phone (which is, since I am testing it on my phone)
EDIT:
Okey, the solution was to request the permissions at runtime...sorry guys

trying to save images Using existing camera apps

i am new to android and trying to make an app using existing camera.

thanks in advance
======================== CAMERA ===============================
public static class App {
public static File file;
public static File directory;
}
private void CreateDirectoryForPictures() {
File path= Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES);
App.directory = new File(path,"Mahapach_Images");
if (!App.directory.exists()) {
App.directory.getParentFile().mkdirs();
}
}
private void takeAPicture(){
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
String imageFileName = "JPEG_" + timeStamp + "_";
CreateDirectoryForPictures();
Intent intent =new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
App.file = new File(App.directory,imageFileName);
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(App.file));
startActivityForResult(intent,1);
}
private void choosePhotoFromGallery() {
Intent intent = new Intent(Intent.ACTION_PICK,android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(intent, 2);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) {
if (requestCode == 1) {
//make it available in the gallery
Intent mediaScanIntent = new Intent (Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
Uri contentUri = Uri.fromFile(App.file);
mediaScanIntent.setData(contentUri);
sendBroadcast(mediaScanIntent);
}
else if (requestCode == 2) {
Uri selectedImage = data.getData();
String[] filePath = {MediaStore.Images.Media.DATA};
Cursor c = getContentResolver().query(selectedImage, filePath, null, null, null);
c.moveToFirst();
int columnIndex = c.getColumnIndex(filePath[0]);
String picturePath = c.getString(columnIndex);
c.close();
Bitmap thumbnail = (BitmapFactory.decodeFile(picturePath));
Log.e("path image from gallery", picturePath + "");
infoWindowImageView.setImageBitmap(thumbnail);
}
}
}

You can easily find many tutorial by just google, and that can do your task like this one i found here
OR
There is better way, use Easy Image library which can do your task with ease click here but remember you have to take care of permission for marshmallow and above android versions.

Save Capture Image in SD card android

I call camera intent and try to save capture image in sd card.but camera intent give me null data.what is the problem i can't understood.my code is as follow
imgBtnPicture.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
String fileName="ashraful.jpg";
String root = Environment.getExternalStorageDirectory().toString();
new File(root + "/photofolder").mkdirs();
File outputfile=new File(root+"/photofolder/", fileName);
Uri outputFileUri = Uri.fromFile(outputfile);
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
startActivityForResult(cameraIntent, CAMERA_REQUEST);
}
});
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == CAMERA_REQUEST && resultCode == RESULT_OK) {
if(data!=null)
{
Bitmap photo = (Bitmap) data.getExtras().get("data");
Bitmap icon1=ResizeBitmap(photo,200,200);
imgBtnPicture.setImageBitmap(icon1);
}
}
}
but i get null data? how to solve my problem?plz help

private void takeNewPicture() {
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
ContentValues values = new ContentValues(3);
values.put(MediaStore.Images.Media.MIME_TYPE, "image/jpeg");
cameraImagePath = getContentResolver().insert(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, cameraImagePath);
startActivityForResult(takePictureIntent, CAMERA_REQUEST);
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == CAMERA_REQUEST && resultCode == RESULT_OK) {
String[] filePathColumn = { MediaStore.Images.Media.DATA };
Uri imageFilePathUri = null;
if (cameraImagePath != null) {
Cursor imageCursor = getContentResolver().query(
cameraImagePath, filePathColumn, null, null, null);
if (imageCursor != null && imageCursor.moveToFirst()) {
int columnIndex = imageCursor.getColumnIndex(filePathColumn[0]);
String filePath = imageCursor.getString(columnIndex);
imageCursor.close();
imageFilePathUri = filePath != null ? Uri
.parse(filePath) : null;
}
}
}
}
cameraImagePath is a Uri object

Read this Android Training post carefully to figure things out. As the post says,
The Android Camera application saves a full-size photo if you give it a file to save into.
so if you did pass the Uri of a file, you should access the image using this Uri.
