How to get file path for pdf in android Marshmallow

I tried to get path from
Intent intent = new Intent();
intent.setType("application/pdf");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(
Intent.createChooser(intent, "Complete action using"), 2);
But I did't get path from Marshamallow, I can get path from lollipop.
How I can get file path from internal storage?

I think you will have to use file provider for that.
Refer this.
https://developer.android.com/reference/android/support/v4/content/FileProvider

When you start an activity using startActivityForResult, the calling activity will get the results (if any) in onActivityResult. You should override that method in your calling activity...
#Override
protected void onActivityResult(int requestCode, int resultCode, #Nullable Intent data) {
}
This will method will get called as soon as the results are returned from the activity started by startActivityForResult. You can use the requestCode parameter to match (or filter out) the results you are expecting. In your case, you should check that requestCode is equal to 2 which is the value you provided in startActivityForResult.
If the requestCode is equal to 2, then you know that you need to process a PDF file. The intent parameter "could" have the path of that PDF file...
#Override
protected void onActivityResult(int requestCode, int resultCode, #Nullable Intent data) {
if(requestCode == 2 && data != null){
//This is the uri to the file (which could be null)
Uri uri = data.getData();
if(uri != null){
Log.i("LOG_TAG", String.format("uri path = %s", uri));
}
}
}
Now, to browse and select files you will do it the following way (Android Kitkat and above...I think)...
Intent intent = new Intent(Intent.ACTION_OPEN_DOCUMENT);
intent.addCategory(Intent.CATEGORY_OPENABLE);
intent.setType("application/pdf");
startActivityForResult(intent, SELECT_FILE_REQUEST_CODE);
Then you receive the selected PDF uri as mentioned above

how to pick a file in SD card?

I'm trying to make an app with Android Studio that can select a file in SD card and get its path, like an OpenFileDialog, I've tried this:
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("file/*");
startActivityForResult(intent, PICKFILE_REQUEST_CODE);
However, it does not work, how can I do it ?

Try this:
Intent mediaIntent = new Intent(Intent.ACTION_GET_CONTENT);
mediaIntent.setType("*/*"); //set mime type as per requirement
startActivityForResult(mediaIntent,0);
You can change type according to your need.
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
// TODO Auto-generated method stub
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 0
&& resultCode == Activity.RESULT_OK) {
Uri uri = data.getData();
Log.d("", "Video URI= " + videoUri);
}
}

Call method when intent closes

I am making a music player application, and I am trying to implement playlists. I have a file chooser in another intent, and I would like the ListView in the mainActivity to update when the file chooser intent closes. how can I call my UpdateListView method when it closes?
start intent:
Intent intent = new Intent(this, FileChooser.class);
startActivity(intent);
Closing intent
public void closeButton(View view){
finish();
}
Any help would be appreciated! thanks!

I assume you are using your own FileChoser class, not a standard Android one:
private static final int FileChooserRequestCode = 666;
Intent intent = new Intent(this, FileChooser.class);
startActivityForResult(intent, FileChooserRequestCode);
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == FillChooserRequestCode) {
if (resultCode == Activity.RESULT_OK) {
// ... file is chosen
String fileName = data.getStringExtra("FileName");
} else {
... dialog is closed
}
}
}
in FileChoser you do
Intent intent = new Intent();
intent.putStringExtra("FileName", fileName);
SetResult(Activity.RESULT_OK, intent);
finish();
and
SetResult(Activity.RESULT_CANCELED);
finish();

You can use startActivityForResult() please refer the link Getting Results From Activity
static final int FILE_CHOOSER_INTENT = 1; // The request code
...
private void chooseFile() {
Intent intent = new Intent(this, FileChooser.class);
startActivityForResult(intent, FILE_CHOOSER_INTENT);
}
Call setResult pass your result data as Intent. for details refer link SetResult function
Override this in your calling activity
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// Check which request we're responding to
if (requestCode == FILE_CHOOSER_INTENT) {
// Make sure the request was successful
if (resultCode == RESULT_OK) {
// The user picked a contact.
// The Intent's data Uri identifies which contact was selected.
// Do something with the contact here (bigger example below)
}
}
}

Unable To Open Images and Video Using onActivityResult - Edited / Updated

I'm trying to accomplish a very simple task:
I need to be able to click the imageButton for video, select from gallery and play, and click the imageButton for images, select an image and view it - ALL USING THE GALLERY
How might this be accomplished?
I believe I'll need to modify my onActivityResult since it does not currently perform as expected.
Current Source:
ImageButton pb = (ImageButton) findViewById(R.id.photos);
pb.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Intent intent = new Intent(Intent.ACTION_PICK);
intent.setType("image/*");
startActivityForResult(intent, SELECT_PHOTO);
}
});
ImageButton vb = (ImageButton) findViewById(R.id.video);
vb.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
.show();
Intent intent = new Intent(Intent.ACTION_PICK);
intent.setType("video/*");
startActivityForResult(intent, SELECT_VIDEO);
}
});
}
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 1) {
if (resultCode == Activity.RESULT_OK) {
Uri selectedVideo = data.getData();
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(selectedVideo, "video/*, image/*");
startActivity(Intent.createChooser(intent,
"Complete action using"));
}
}
;
}
}
Edit:
I have updated my source to reflect the most recent answer - however I am still unable to open images - I continue to get the "unable to play video" when attmempting to view an image.

checkout this for video:
Intent intent = new Intent(Intent.ACTION_PICK);
intent.setType("video/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent,"Select Video"), SELECT_VIDEO);
and this for images:
Intent intent = new Intent(Intent.ACTION_PICK);
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent,"Select Images"), SELECT_PHOTO);
and in onActivityResult try this :
if (requestCode==SELECT_VIDEO) {
//take whatever video action
}else if(requestCode==SELECT_PHOTO){
//take whatever image action
}

Building a Camera App - Receive

I am new to Android programming and I'm writing an application in Java that opens the camera take a photo and save it. I made it via Intents but I can't see onActivityResult running.
I have tested it into my phone (Samsung Galaxy S) and when I take the photo I receive a preview of that photo having two buttons one Save and the other Cancel. I haven't added something to my code to do this so I think it's something that camera does. I want after capturing the image to run onActivityResult (after I press the Save button on the preview).
But how I'm going to return a result to start onActivityResult after pressing the Button Save on the preview?
I FORGOT to tell that after i press save my entire app is terminated.
Here is my Code
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
TakePicButton = (Button) findViewById(R.id.TakePicture);
TakePicButton.setOnClickListener((android.view.View.OnClickListener) this);
}
#Override
public void onDestroy(){
super.onDestroy();
}
#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();
} else if (resultCode == RESULT_CANCELED) {
Toast.makeText(this, "Picture was not taken", Toast.LENGTH_SHORT);
} else {
Toast.makeText(this, "Picture was not taken", Toast.LENGTH_SHORT);
}
}
public void onClick(View v) {
// TODO Auto-generated method stub
if(v.getId() == R.id.TakePicture){
// create Intent to take a picture and return control to the calling application
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
fileUri = getOutputMediaFileUri(MEDIA_TYPE_IMAGE); // create a file to save the image
intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri); // set the image file name
// start the image capture Intent
startActivityForResult(intent, CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE);
}
}

try the below code, you will have to modify it a bit, it will help you get From Library and From Camera both, the SELECT_PICTURE is used for getting image from library
public void onActivityResult(int requestCode, int resultCode, Intent data) {
switch (requestCode) {
case SELECT_PICTURE:
Uri selectedImageUri = data.getData();
filemanagerstring = selectedImageUri.getPath();
selectedImagePath = getPath(selectedImageUri);
if (selectedImagePath != null)
myFile = new File(selectedImagePath);
else if (filemanagerstring != null)
myFile = new File(filemanagerstring);
if (myFile != null) {
Bitmap bmp_fromGallery = decodeImageFile(selectedImagePath);
break;
case CAMERA_REQUEST:
Bitmap bmp_Camera = (Bitmap) data.getExtras().get("data");
break;
default:
break;
}
}
