i want to browse all Audio files, but i am getting error like No application can perform this action.. this is my code for browse activity...
--> private static final int SELECT_MUSIC = 1;
String selectedImagePath;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
((Button) findViewById(R.id.browse)).setOnClickListener(new OnClickListener() {
public void onClick(View arg0) {
// in onCreate or any event where your want the user to
// select a file
Intent intent = new Intent();
intent.setType("music/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent,"Select File"), SELECT_MUSIC);
}
});
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
if (requestCode == SELECT_MUSIC) {
Uri selectedImageUri = data.getData();
selectedImagePath = getPath(selectedImageUri);
}
}
}
public String getPath(Uri uri) {
String[] projection = {MediaStore.Images.Media.DATA};
Cursor cursor = managedQuery(uri, projection, null, null, null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Audio.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
and i have also added permission to menifest file:: READ_PHONE_STATE
what's problem? any idea?
Thanks..
It means that No Application perform that action. Why? because None of the installed Applications perform that action. It has nothing to do with permissions.
You are probably running this on an emulator, which does not include any directory browser application.
The setType method is working with MIME type values only.
If you really just need the handling of music files "audio/" should be ok (as mentioned before). To be more flexible, you should try to detect the MIME code of the file.
Here is a code snippit how this may look like:
FileNameMap fileNameMap = URLConnection.getFileNameMap();
type = fileNameMap.getContentTypeFor("file://" + file.getPath());
Or (pre Gingerbread)
if (!file.getName().contains("."))
return null;
String ext = (String) file.getName().subSequence(
file.getName().lastIndexOf(".") + 1,
file.getName().length());
MimeTypeMap mimeMap = MimeTypeMap.getSingleton();
type = mimeMap.getMimeTypeFromExtension(ext);
I usually use the combination of both methods (use the pre Gingerbread version if the first approach fails).
You can use:
intent.setType("audio/*"); instead of intent.setType("music/*");
Then you can choose a track, not a playlist.
Could you find a way to choose a playlist?
I have the same problem, looking for a way to open and choose a playlist.

I am trying to fetch a file this way:
final Intent chooseFileIntent = new Intent(Intent.ACTION_GET_CONTENT);
String[] mimetypes = {"application/pdf"};
chooseFileIntent.setType("*/*");
chooseFileIntent.addCategory(Intent.CATEGORY_OPENABLE);
if (chooseFileIntent.resolveActivity(activity
.getApplicationContext().getPackageManager()) != null) {
chooseFileIntent.putExtra(Intent.EXTRA_MIME_TYPES, mimetypes);
activity.startActivityForResult(chooseFileIntent, Uploader.PDF);
}
Then in onActivityResult :
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
}
According to many threads I'm supposed to fetch the file name from the intent with data.getData().getPath(), the file name I'm expecting is my_file.pdf, but instead I'm getting this :
/document/acc=1;doc=28
So what to do? Thanks for your help.
I am trying to fetch a file
Not with that code. That code is asking the user to pick a piece of content. This may or may not be a file.
According to many threads I'm supposed to fetch the file name from the intent with data.getData().getPath()
That was never correct, though it tended to work on older versions of Android.
So what to do?
Well, that depends.
If you wish to only accept files, integrate a file chooser library instead of using ACTION_GET_CONTENT. (UPDATE 2019-04-06: since Android Q is banning most filesystem access, this solution is no longer practical)
If you are willing to allow the user to pick a piece of content using ACTION_GET_CONTENT, please understand that it does not have to be a file and it does not have to have something that resembles a filename. The closest that you will get:
If getScheme() of the Uri returns file, your original algorithm will work
If getScheme() of the Uri returns content, use DocumentFile.fromSingleUri() to create a DocumentFile, then call getName() on that DocumentFile — this should return a "display name" which should be recognizable to the user
To get the real name and to avoid getting a name that looks like "image: 4431" or even just a number, you can write code as recommended by CommonsWare.
The following is an example of a code that selects a single pdf file, prints its name and path to the log, and then sends the file by email using its uri.
private static final int FILEPICKER_RESULT_CODE = 1;
private static final int SEND_EMAIL_RESULT_CODE = 2;
private Uri fileUri;
private void chooseFile() {
Intent fileChooser = new Intent(Intent.ACTION_GET_CONTENT);
fileChooser.setType("application/pdf");
startActivityForResult(Intent.createChooser(fileChooser, "Choose one pdf file"), FILEPICKER_RESULT_CODE);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, #Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == FILEPICKER_RESULT_CODE) {
if (resultCode == RESULT_OK) {
fileUri = data != null ? data.getData() : null;
if (fileUri != null) {
DocumentFile d = DocumentFile.fromSingleUri(this, fileUri);
if (d != null) {
Log.d("TAG", "file name: " + d.getName());
Log.d("TAG", "file path: " + d.getUri().getPath());
sendEmail(fileUri);
}
}
}
}
}
private void sendEmail(Uri path) {
String email = "example#gmail.com";
Intent intent = new Intent(android.content.Intent.ACTION_SEND);
intent.setType("application/octet-stream");
intent.putExtra(android.content.Intent.EXTRA_SUBJECT, "PDF file");
String[] to = { email };
intent.putExtra(Intent.EXTRA_EMAIL, to);
intent.putExtra(Intent.EXTRA_TEXT, "This is the pdf file...");
intent.putExtra(Intent.EXTRA_STREAM, path);
startActivityForResult(Intent.createChooser(intent, "Send mail..."), SEND_EMAIL_RESULT_CODE);
}
hope it helps.
I use this code to use Intent to select any type of file and get it's path in my application
//this when button click
public void onBrowse(View view) {
Intent chooseFile;
Intent intent;
chooseFile = new Intent(Intent.ACTION_GET_CONTENT);
chooseFile.addCategory(Intent.CATEGORY_OPENABLE);
chooseFile.setType("file/*");
intent = Intent.createChooser(chooseFile, "Choose a file");
startActivityForResult(intent, ACTIVITY_CHOOSE_FILE);
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode != RESULT_OK) return;
String path = "";
if(requestCode == ACTIVITY_CHOOSE_FILE)
{
Uri uri = data.getData();
String FilePath = getRealPathFromURI(uri); // should the path be here in this string
System.out.print("Path = " + FilePath);
}
}
public String getRealPathFromURI(Uri contentUri) {
String [] proj = {MediaStore.Images.Media.DATA};
Cursor cursor = getContentResolver().query( contentUri, proj, null, null,null);
if (cursor == null) return null;
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
the problem when the file browser open i can't select a file it seems like it's not enable when i pressed on a file nothing happend so what is the wrong with this code
i upload a screenshot from my android mobile
image
Thanks in advance
the type of a file is .txt
Then use text/plain as a MIME type. As Ian Lake noted in a comment, file/* is not a valid MIME type.
Beyond that, delete getRealPathFromURI() (which will not work). There is no path, beyond the Uri itself. You can read in the contents identified by this Uri by calling openInputStream() on a ContentResolver, and you can get a ContentResolver by calling getContentResolver() on your Activity.
Change the line :
chooseFile.setType("file/*");
to
chooseFile.setType("*/*");
This will help you choose any type of file.
Hello friends I am using the following code to pic a video from gallery..
private static final int SELECT_VIDEO = 3;
Intent intent = new Intent();
intent.setType("video/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent,"Select a video"), SELECT_VIDEO);
On activity result:
#Override
protected void onActivityResult( int requestCode, int resultCode, Intent data)
{
try{
if (resultCode == RESULT_OK) {
if (requestCode == SELECT_VIDEO)
{
Uri selectedImageUri = data.getData();
videopath = getPath(selectedImageUri);
}
}
}catch(Exception e){
// MLog.e("On Activity result.", "Error: "+e);
}
}
//get path method
public String getPath(Uri uri) {
String[] projection = { MediaStore.Video.Media.DATA, MediaStore.Video.Media.SIZE, MediaStore.Video.Media.DURATION};
Cursor cursor = managedQuery(uri, projection, null, null, null);
cursor.moveToFirst();
String filePath = cursor.getString(cursor.getColumnIndexOrThrow(MediaStore.Video.Media.DATA));
int fileSize = cursor.getInt(cursor.getColumnIndexOrThrow(MediaStore.Video.Media.SIZE));
long duration = TimeUnit.MILLISECONDS.toSeconds(cursor.getInt(cursor.getColumnIndexOrThrow(MediaStore.Video.Media.DURATION)));
return filePath;
}
Now using above code I am getting null for video path in android 4.4. Can any one help me and let me know what should I have to use that I can pic the video from gallery successfully in android 4.4.
Now using above code I am getting null for video path in android 4.4.
You will get null in many cases, but particularly on Android 4.4+. That is because there does not have to be a file that you can access that corresponds to the video. A Uri is not necessarily a File.
You need to get rid of getPath() and use the Uri properly. For example, MediaPlayer and VideoView can work with the Uri directly. If you need the bytes of the video, use openInputStream() on ContentProvider to read in the video.
I want to play a video file recorded to be played in the mediaplayer of android.I want to call the media player through the intent and want to play the corresponding file of the passed uri.When I was trying I am getting an exception ActivityNotFound can anyone help me with a code.
#Override

Toast.makeText(VedioRecording.this, uriVideo.getPath(),
Toast.LENGTH_LONG).show();
}
} else if (resultCode == RESULT_CANCELED) {
uriVideo = null;
Toast.makeText(VedioRecording.this, "Cancelled!", Toast.LENGTH_LONG)
.show();
}
if (requestCode == 2) {
selectedImageUri = data.getData();
// OI FILE Manager
filemanagerstring = selectedImageUri.getPath();
// MEDIA GALLERY
selectedImagePath = getPath(selectedImageUri);
Intent intent1 = new Intent(android.provider.MediaStore.INTENT_ACTION_MUSIC_PLAYER).setData(selectedImageUri);
startActivityForResult(intent1, 3);
// videoviewPlay.setVideoURI(selectedImageUri);

private String getPath(Uri uri) {
String[] projection = { MediaStore.Video.Media.DATA };
Cursor cursor = managedQuery(uri, projection, null, null, null);
if (cursor != null) {
// HERE YOU WILL GET A NULLPOINTER IF CURSOR IS NULL
// THIS CAN BE, IF YOU USED OI FILE MANAGER FOR PICKING THE MEDIA
int column_index = cursor
.getColumnIndexOrThrow(MediaStore.Video.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
} else {
return null;
}
}
}
this is my code i am geting activitynotfound exception
The most common scenario in which you get an ActivityNotFound exception is when you attempt to launch an Activity you have created without declaring it in the manifest.
Post your code that you use to launch the Activity to be sure. If you're trying to use an activity that should be provided by the framework externally from your application, you may just be setting up the Intent incorrectly
Update after code posted...
Your code seems to be using the intent action INTENT_ACTION_MUSIC_PLAYER and passing an image url as data (is it the path to an image or are your variables just misnamed?). You get an ActivityNotFoundException because the system doesn't have any intent receivers registered to handle that scenario. Also, if you look at the documentation for this constant, you'll see that they marked it deprecated at some point:
http://developer.android.com/reference/android/provider/MediaStore.html#INTENT_ACTION_MUSIC_PLAYER
I would normally use Intent.ACTION_VIEW and pass a mime type along with the data. Something like the following...
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.parse(pathToVideoFile), "video/*");
startActivity(intent);
By passing the mime type of "video/*" to setDataAndType, you're being more specific with your request to the system.
If you want to query the system to find out if an Intent can be handled (meaning that the user's device running your code has an Activity registered that can handle the Intent), you can use the PackageManager.queryIntentActivities method:
queryIntentActivities
String extension = MimeTypeMap
.getFileExtensionFromUrl(selectedImagePath);
String mimeType = MimeTypeMap.getSingleton()
.getMimeTypeFromExtension(extension);
Intent mediaIntent = new Intent(Intent.ACTION_VIEW);
mediaIntent.setDataAndType(Uri.parse(selectedImagePath),
mimeType);
startActivity(mediaIntent);
this is the code that helped me
How can I get a user to select from the native gallery in Android, rather than other gallery-like applications such as ASTRO File Manager?
The following code gives a list of activities that can select an image:
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
List<ResolveInfo> infos = activity.getPackageManager().queryIntentActivities(intent, 0);
If I then do something like this:
activity.startActivityForResult(Intent.createChooser(intent, "Select Picture"), REQUEST_CHOOSE_IMAGE);
then if the user has more than one application that can act like a gallery (such as ASTRO File Manager), s/he is prompted to select one of them, with no "set as default" option.
I don't want the user to be prompted to choose between them each time, so I'd like to just use the native gallery.
The hacky code sample below uses a whitelist to test for known native gallery names:
for (ResolveInfo info : infos) {
if ( 0==info.activityInfo.name.compareTo("com.cooliris.media.Gallery")
|| 0==info.activityInfo.name.compareTo("com.htc.album.CollectionsActivity")
) {
// found the native gallery
doSomethingWithNativeGallery();
}
}
Feels kinda dirty. Is there a better way? I suspect I'm missing something in my intent.
I didn't get last part of your code.
To start the native gallry what i did is -
public void upload(){
Intent photoPickerIntent = new Intent(Intent.ACTION_GET_CONTENT);
photoPickerIntent.setType("image/jpg");
photoPickerIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse("file:///sdcard/Pictures/image.jpg"));
startActivityForResult(photoPickerIntent, 1);
}
Call the upload() where you like to start the native gallery.
Then to get that image info i did -
/**
* Retrieves the returned image from the Intent, inserts it into the MediaStore, which
* automatically saves a thumbnail. Then assigns the thumbnail to the ImageView.
* #param requestCode is the sub-activity code
* #param resultCode specifies whether the activity was cancelled or not
* #param intent is the data packet passed back from the sub-activity
*/
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent intent) {
super.onActivityResult(requestCode, resultCode, intent);
if (resultCode == RESULT_CANCELED) {
return;
}
else if(resultCode == RESULT_OK) {
Uri uri = intent.getData();
String path = getPath(uri);
Log.i("PATH", path);
data = path;
return;
}
uplad();
}
public String getPath(Uri uri) {
String[] projection = { MediaStore.Images.Media.DATA };
Cursor cursor = managedQuery(uri, projection, null, null, null);
int column_index = cursor
.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
If you wouldn't get your answer, clear what you like to do
