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

I have the following code on my button, which allows me to click a button and choose a PDF file. How do I get the path of the PDF file, and actually do something with the file (because right now I can only click on the file and nothing happens). I want the image to be put in an API do to something to the image.
final Intent galleryIntent = new Intent(Intent.ACTION_GET_CONTENT);
galleryIntent.setType("*/*");
startActivityForResult(galleryIntent, RESULT_LOAD_IMAGE);
You must override the onActivityResult in order to get what you need.
You will be able to get what you want (the file path) with the resulting intent. Like this:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent intent)
{
if(resultCode == RESULT_OK) {
Uri fileUri = intent.getData();
}
}
I'm making a program that asks the user to find a file which could be stored on the sdcard or the internal card of the phone. I know that in order to open the default file explorer in the phone I must use this code:
Intent intent = new Intent();
intent.setAction(Intent.ACTION_GET_CONTENT);
intent.setType("file/*");
startActivity(intent);
However, my problem is related with the communication with the File Explorer, how can I get the address of the file the user selected.
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("file/*");
startActivityForResult(intent, YOUR_REQUEST_CODE);
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
switch (requestCode) {
case YOUR_REQUEST_CODE:
//get the uri from data's extras
break;
}
//do whatever you want with uri
} else {
Toast.makeText(this, "Wrong result", Toast.LENGTH_SHORT).show();
}
}
When I click a button,show a file browser,I can choose a folder and return it's path.I get this path to copy file to that path.
But I have no idea of How I could implement this.
I have yet looking for this question in Stackoverflow but I haven't find a clear answer to my question.
I saw some libary of filebrowserview like "https://github.com/psaravan/FileBrowserView",but not work.
Use intent for that!
First start start activity for result like this:
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("file/*");
startActivityForResult(intent, PICKFILE_REQUEST_CODE);
Override this method in your activity, it will get called when activity you just started returns. You can handle result codes such as canceled or successful.
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
String Fpath = data.getDataString();
//TODO handle your request here
super.onActivityResult(requestCode, resultCode, data);
}
Another approach is to use library such as NoNonsense-FilePicker.
I am trying to use an intent to import a file form the device to my app. I am using Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
My question is... I know for the intent I need to have onActivityResult() method, but I already have one for another intent being used the the class, is there a way I can have two onActivityResult() methods for two intents.
onActivityResult(int requestCode, Result resultCode, Intent data)
use differnet requestCode for different intents
startActivityForResult(intent, requestCodeForIntentOne);
startActivityForResult(intent, requestCodeForIntentTwo);
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
if(requestCode==requestForIntentOne)
{}
if(requestCode==requestForIntentTwo)
{}
}
when you call startActivityForResult(), you supply a requestCode. That will match the value of the same name you get in onActivityResult()
So you can do :
if (requestCode == requestCodeA) {
//handle case 1
} else if (requestCode == requestCodeB) {
//handle case 1
}
I am attempting to launch the built-in camera to take a picture, a picture that will have a name specified by the activity launching the camera. (code below)
When the camera returns, onActivityResult() goes straight to resultCode == Activity.RESULT_CANCELED. Any explanation for this and solutions would be greatly appreciated.
The camera indeed does take the image, I can see it in my sdcard with a file viewer, but its name is the stock one from the camera. How can I get the name of this taken image to be the one supplied by the activity?
Camera intent code
Intent camera = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File image = new File("Team image.jpg");
camera.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
camera.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(image));
camera.putExtra(MediaStore.Images.Media.TITLE, "Team image");
startActivityForResult(camera, PICTURE_RESULT);
activityresult code
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data){
if(requestCode == PICTURE_RESULT){
if(resultCode == Activity.RESULT_OK) {
if(data!=null){
Bitmap image = BitmapFactory.decodeFile(data.getExtras().get(MediaStore.Images.Media.TITLE).toString());
grid.add(image);
images.addItem(image);
}
if(data==null){
Toast.makeText(Team_Viewer.this, "no data.", Toast.LENGTH_SHORT).show();
}
}
else if(resultCode == Activity.RESULT_CANCELED) {
Toast.makeText(Team_Viewer.this, "Picture could not be taken.", Toast.LENGTH_SHORT).show();
}
}
}
Have you mark the launch mode of your activity as "singleInstance"?
That may cause your first problem.
My camera goes normal when I remove the "singleInstance".
The two issues are likely related, having to do with the way you are creating the file reference that passes to the camera. If you want your image file to save to the SD Card, you need to create a file reference that includes a full-path to that location, not just a filename. For example, this code would save the image file on the SD card root:
Intent camera = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File image = new File(Environment.getExternalStorageDirectory(),"TeamImage.jpg");
camera.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(image));
startActivityForResult(camera, PICTURE_RESULT);
I also changed your filename to not include a space; only because I'm not certain that the Camera application won't blow up on that piece also. Since the Camera is getting confused trying to open and write to your file location, that is likely why you always return with RESULT_CANCELED. You don't need the WRITE_EXTERNAL_STORAGE permission here, since the Camera app is doing the SD Card access.
One more note: I don't believe other MediaStore extras can be passed with this Intent. Typically, if you want metadata to be attached to your image, you have to insert the Uri reference with that metadata into the MediaStore ContentProvider prior to saving the image to disk.
Hope that helps!
Not sure what's wrong with your code, here's what works for me:
Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, CAMERA_PIC_REQUEST);
and
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == Activity.RESULT_OK) {
switch (requestCode) {
case CAMERA_PIC_REQUEST:
Bitmap b = (Bitmap) data.getExtras().get("data");
if (b != null) {
updateThumbnail(b);
if (mBitmap != b) {
b.recycle();
}
}
break;
}
}
