Pick any file using intent in android

I'm using following method to call pick any file but it doesn't work properly.
private void fileIntent(int file)
{
if ((ActivityCompat.checkSelfPermission(ICShowFileCabinetDetails.this, Manifest.permission.WRITE_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) && Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
requestPermissions(new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, file);
} else {
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("*/*");
startActivityForResult(Intent.createChooser(intent, "Select File"), file);
}
}
Following permissions are set in manifest
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
OnActivtyresult
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == SELECT_FILE && data != null) {
try {
mProPic = MediaStore.Images.Media.getBitmap(getApplicationContext().getContentResolver(), data.getData());
Uri selectedImage = data.getData();
String[] filePathColumn = {MediaStore.Images.Media.DATA};
Cursor cursor = getContentResolver().query(selectedImage,
filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
String picturePath = cursor.getString(columnIndex);
// String filename = selectedImage.getLastPathSegment();
String[] filenames = picturePath.split("\\/");
int count = filenames.length;
String name = filenames[count - 1];
imagepickerselected = 1;
UploadIamgeinServer(1, name);
} catch (IOException e) {
e.printStackTrace();
}
}
}
Choose file getting open whenever i click to choose file in button click. But all files are shown like hidden except images, Click doest work. Without method in it button click works fine. If anyone found errors in code please let me know.
Thanks

try this code this my code only for .xls use yours.
or add read and write permission in manifest file
oncreate declare permission
if (ContextCompat.checkSelfPermission(this,
Manifest.permission.WRITE_EXTERNAL_STORAGE)
!= PackageManager.PERMISSION_GRANTED) {
if (ActivityCompat.shouldShowRequestPermissionRationale(this,
Manifest.permission.WRITE_EXTERNAL_STORAGE)) {
} else {
ActivityCompat.requestPermissions(this,
new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE},23
);
}
}
onclick of you button write this code
path= String.valueOf(Environment.getExternalStorageDirectory());
File file = new File(path);
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setDataAndType(Uri.fromFile(file), "application/vnd.ms-excel");
try {
startActivityForResult(pdfOpenintent.createChooser(intent, "Select file"), 0); }
catch (ActivityNotFoundException e) {
}
onactivityresult yud get file path
public void onActivityResult(int requestCode, int resultCode, Intent result){
if (resultCode == RESULT_OK){
if (requestCode == 0) {
Uri data = result.getData();
else{
// CommonMethods.ShowMessageBox(CraneTrackActivity.this, "Invalid file type");
Toast.makeText(Import_act.this,"Wrong File Selected ", Toast.LENGTH_SHORT).show();
}
}
}
}

I think you should add like this intent.addCategory(Intent.CATEGORY_OPENABLE);

How to upload particular image on particular imageView click from gallery and camera in android

i have 4 diffrent imageview and try to click on all to upload diffrent images like LIcence,Rc,Profile etc . I want to uploaded image from gallery or camera dialog..

Please check my updated answer. This is just an example. Hope you understand from this
ImageView profile_pic;

Log.d("picUri", picUri.toString());
Log.d("filePath", filePath);
imageView.setImageURI(picUri);
}
if (requestCode == CAMERA_REQUEST && resultCode == Activity.RESULT_OK) {
Bitmap photo = (Bitmap) data.getExtras().get("data");
imageView.setImageBitmap(photo);
}
}
}

EDIT
Since you are using recyclerview or listview kind of view, you can associate tag to each viewholder and then use that tag for resolving imageview. Now you can get unique tag based on position in view. For eg in recyclerview you can use getAdapterPosition().
Associate OnClicks of each imageview with a request code. In onActivityResult resolve them and put images accordingly.

I would like to suggest to refer this site, It's implementation is easy and straight forward...
http://www.coderzheaven.com/2012/04/20/select-an-image-from-gallery-in-android-and-show-it-in-an-imageview/

In addition to the perfectly working answer by #paras, if someone wants to include the Camera option also then please refer to the below steps:
Add a dialog box which pops-up on image click and asks to chose either Camera or Gallery:
final CharSequence[] items = {"Camera", "Gallery", "Cancel"};
AlertDialog.Builder builder = new AlertDialog.Builder(PhotoActivity.this);
builder.setTitle("Add Photo!");
builder.setItems(items, new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int item) {
if (items[item].equals("Camera")) {
openCamera();
} else if (items[item].equals("Gallery")) {
openGallery();
} else if (items[item].equals("Cancel")) {
dialog.dismiss();
}
}
});
builder.show();
Use this method to open the Camera intent:
private void openCamera() {
Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, REQUEST_CAMERA);
}
Now in the onActivityResult() method, include this to check whether the intent is from Camera:
if (requestCode == REQUEST_CAMERA) {
Bundle bundle = data.getExtras();
final Bitmap bitmap = (Bitmap) Objects.requireNonNull(bundle).get("data");
imageView.setImageBitmap(bitmap);
}

Confused about sending mail

I am trying to send an e-mail with a file attached,So I have downloaded sample project and working on it.The problem is everytime I get the same message "couldnt attach file (sorry for my english)
So far I have this .
public class MainActivity extends Activity implements OnClickListener {
EditText et_address, et_subject, et_message;
String address, subject, message, file_path;
Button bt_send, bt_attach;
TextView tv_attach;
private static final int PICK_IMAGE = 100;
Uri URI = null;
int columnindex;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
initializeViews();
bt_send.setOnClickListener(this);
bt_attach.setOnClickListener(this);
}
private void initializeViews() {
et_address = (EditText) findViewById(R.id.et_address_id);
et_subject = (EditText) findViewById(R.id.et_subject_id);
et_message = (EditText) findViewById(R.id.et_message_id);
bt_send = (Button) findViewById(R.id.bt_send_id);
bt_attach = (Button) findViewById(R.id.bt_attach_id);
tv_attach = (TextView) findViewById(R.id.tv_attach_id);
}
#Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.bt_attach_id:
openGallery();
break;
case R.id.bt_send_id:
try {
address = et_address.getText().toString();
subject = et_subject.getText().toString();
message = et_message.getText().toString();
String emailAddresses[] = { address };
Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL,
emailAddresses);
emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, subject);
emailIntent.setType("plain/text");
emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, message);
if (URI != null)
emailIntent.putExtra(Intent.EXTRA_STREAM, URI);
startActivity(emailIntent);
} catch (Exception e) {
e.printStackTrace();
}
break;
}
}
private void openGallery() {
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, "Select Picture"),
PICK_IMAGE);
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == PICK_IMAGE && resultCode == RESULT_OK) {
Uri selectedImage = data.getData();
String[] filePathColumn = { MediaStore.Images.Media.DATA };
Cursor cursor = getContentResolver().query(selectedImage,
filePathColumn, null, null, null);
cursor.moveToFirst();
columnindex = cursor.getColumnIndex(filePathColumn[0]);
file_path = cursor.getString(columnindex);
// Log.e("Attachment Path:", attachmentFile);
tv_attach.setText(file_path);
URI = Uri.parse("file://" + file_path);
cursor.close();
}
}

Your processing of the Uri returned from the gallery looks overcomplicated. You are taking a Uri and processing it to produce a Uri.
I think your onActivityResult() method should be more like:
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == PICK_IMAGE && resultCode == RESULT_OK) {
URI = data.getData();
}
}
This is better as it's also not good practice to pass a "file://" Uri to an external application in case the external email application doesn't have access to the file.

how to open the gallery?

I need to open the images gallery via code in my app.(only opening the gallery, the user is not going to select any image). I searched and found lots of ways but some of them worked only for selecting an image and other ways never worked.e.g.
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);//
startActivityForResult(Intent.createChooser(intent, "Select Picture"),SELECT_IMAGE);
or
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(
"content://media/internal/images/media"));
startActivity(intent);
how may I open the gallery?

public void pickPhoto(View view)
{
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, "Select Picture"),1);
}
Here:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE) {
if (resultCode == RESULT_OK) {
// Image captured and saved to fileUri specified in the Intent
Toast.makeText(this, "Image saved to:\n" +
data.getData(), Toast.LENGTH_LONG).show();
Uri curImageURI = data.getData();
Bitmap bit = getRealPathFromURI(curImageURI);
imageView.setImageBitmap(bit);
} else if (resultCode == RESULT_CANCELED) {
// User cancelled the image capture
} else {
// Image capture failed, advise user
}
}
and
public String getRealPathFromURI(Uri contentUri) {
String[] proj = { MediaStore.Images.Media.DATA };
#SuppressWarnings("deprecation")
android.database.Cursor cursor = managedQuery(contentUri, proj, null,
null, null);
int column_index;
try {
column_index = cursor
.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
} catch (Exception e) {
return null;
}
}
CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE is the final number in the "startActivityForResult(Intent.createChooser(intent, "Select Picture"),1);"
in this case '1' so you'd need to change it to 1 or declare it as a global variable

android - getpath method returns incorrect address

I used startActivityForResult to pick a picture from gallery and then used onActivityResult for bring the result.
when i use getPath() for the intent result to send the path to another activity to set the source of that picture , the path is incorrect and is another way that the picture is not located there .
the picture is located in sdcard and located at : "mnt/sdcard/pictures/lambo"---- but getpath() his returns : "external/images/media/17
photopicker :
private void photopicker() {
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, "Select Picture"), SELECT_PHOTO);
}
onActivityResult :
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent imageReturnedIntent) {
super.onActivityResult(requestCode, resultCode, imageReturnedIntent);
switch(requestCode) {
case SELECT_PHOTO:
if(resultCode == RESULT_OK){
Uri selectedImage = imageReturnedIntent.getData();
String add;
add = selectedImage.getPath(); // don't work
InputStream imageStream = null;
try {
imageStream = getContentResolver().openInputStream(selectedImage);
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
selectedPhoto = BitmapFactory.decodeStream(imageStream);
// add = selectedImage.getPath(); // don't work
Intent intent = new Intent(MainActivity.this, PicViewer.class);
intent.putExtra("add", add);
startActivity(intent);
}
}
}

You can try this:
public String getRealPathFromURI(Uri contentUri) {
String[] proj = { MediaStore.Images.Media.DATA };
Cursor cursor = managedQuery(contentUri, proj, null, null, null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
