Android opening a file with ACTION_GET_CONTENT results into different Uri's
Use below code.This will work for sure.
public static String getPath(Context context, Uri uri) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
// DocumentProvider
if (DocumentsContract.isDocumentUri(context, uri)) {
// ExternalStorageProvider
if (isExternalStorageDocument(uri)) {
final String docId = DocumentsContract.getDocumentId(uri);
final String[] split = docId.split(":");
final String type = split[0];
if ("primary".equalsIgnoreCase(type)) {
return Environment.getExternalStorageDirectory() + "/" + split[1];
}
// TODO handle non-primary volumes
}
// DownloadsProvider
else if (isDownloadsDocument(uri)) {
final String id = DocumentsContract.getDocumentId(uri);
final Uri contentUri = ContentUris.withAppendedId(Uri.parse("content://downloads/public_downloads"), Long.valueOf(id));
return getDataColumn(context, contentUri, null, null);
}
// MediaProvider
else if (isMediaDocument(uri)) {
final String docId = DocumentsContract.getDocumentId(uri);
final String[] split = docId.split(":");
final String type = split[0];
Uri contentUri = null;
if ("image".equals(type)) {
contentUri = MediaStore.Images.Media.EXTERNAL_CONTENT_URI;
} else if ("video".equals(type)) {
contentUri = MediaStore.Video.Media.EXTERNAL_CONTENT_URI;
} else if ("audio".equals(type)) {
contentUri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
}
final String selection = "_id=?";
final String[] selectionArgs = new String[]{split[1]};
return getDataColumn(context, contentUri, selection, selectionArgs);
}
}
}
// MediaStore (and general)
else if ("content".equalsIgnoreCase(uri.getScheme())) {
// Return the remote address
if (isGooglePhotosUri(uri))
return uri.getLastPathSegment();
return getDataColumn(context, uri, null, null);
}
// File
else if ("file".equalsIgnoreCase(uri.getScheme())) {
return uri.getPath();
}
return null;
}
public static String getDataColumn(Context context, Uri uri, String selection, String[] selectionArgs) {
Cursor cursor = null;
final String column = "_data";
final String[] projection = {column};
try {
cursor = context.getContentResolver().query(uri, projection, selection, selectionArgs, null);
if (cursor != null && cursor.moveToFirst()) {
final int index = cursor.getColumnIndexOrThrow(column);
return cursor.getString(index);
}
} finally {
if (cursor != null)
cursor.close();
}
return null;
}
public static boolean isExternalStorageDocument(Uri uri) {
return "com.android.externalstorage.documents".equals(uri.getAuthority());
}
/**
* @param uri The Uri to check.
* @return Whether the Uri authority is DownloadsProvider.
*/
public static boolean isDownloadsDocument(Uri uri) {
return "com.android.providers.downloads.documents".equals(uri.getAuthority());
}
/**
* @param uri The Uri to check.
* @return Whether the Uri authority is MediaProvider.
*/
public static boolean isMediaDocument(Uri uri) {
return "com.android.providers.media.documents".equals(uri.getAuthority());
}
/**
* @param uri The Uri to check.
* @return Whether the Uri authority is Google Photos.
*/
public static boolean isGooglePhotosUri(Uri uri) {
return "com.google.android.apps.photos.content".equals(uri.getAuthority());
}
Use the below code to browse the file in any format.
public void browseClick() {
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("*/*");
intent.addCategory(Intent.CATEGORY_OPENABLE);
//intent.putExtra("browseCoa", itemToBrowse);
//Intent chooser = Intent.createChooser(intent, "Select a File to Upload");
try {
//startActivityForResult(chooser, FILE_SELECT_CODE);
startActivityForResult(Intent.createChooser(intent, "Select a File to Upload"),FILE_SELECT_CODE);
} catch (Exception ex) {
System.out.println("browseClick :"+ex);//android.content.ActivityNotFoundException ex
}
}
Then get that file path in the onActivityResult like below.
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == FILE_SELECT_CODE) {
if (resultCode == RESULT_OK) {
try {
Uri uri = data.getData();
if (filesize >= FILE_SIZE_LIMIT) {
Toast.makeText(this,"The selected file is too large. Selet a new file with size less than 2mb",Toast.LENGTH_LONG).show();
} else {
String mimeType = getContentResolver().getType(uri);
if (mimeType == null) {
String path = getPath(this, uri);
if (path == null) {
filename = FilenameUtils.getName(uri.toString());
} else {
File file = new File(path);
filename = file.getName();
}
} else {
Uri returnUri = data.getData();
Cursor returnCursor = getContentResolver().query(returnUri, null, null, null, null);
int nameIndex = returnCursor.getColumnIndex(OpenableColumns.DISPLAY_NAME);
int sizeIndex = returnCursor.getColumnIndex(OpenableColumns.SIZE);
returnCursor.moveToFirst();
filename = returnCursor.getString(nameIndex);
String size = Long.toString(returnCursor.getLong(sizeIndex));
}
File fileSave = getExternalFilesDir(null);
String sourcePath = getExternalFilesDir(null).toString();
try {
copyFileStream(new File(sourcePath + "/" + filename), uri,this);
} catch (Exception e) {
e.printStackTrace();
}
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
}
private void copyFileStream(File dest, Uri uri, Context context)
throws IOException {
InputStream is = null;
OutputStream os = null;
try {
is = context.getContentResolver().openInputStream(uri);
os = new FileOutputStream(dest);
byte[] buffer = new byte[1024];
int length;
while ((length = is.read(buffer)) > 0) {
os.write(buffer, 0, length);
}
} catch (Exception e) {
e.printStackTrace();
} finally {
is.close();
os.close();
}
}
After this you can open this file from your application external storage where you saved the file with appropriate action.
URI from Intent.ACTION_GET_CONTENT into File
I've done this method to convert Uri from Intent.ACTION_GET_CONTENT to real path:
public static String getRealPathFromUri(Activity activity, Uri contentUri) {
String[] proj = { MediaStore.Images.Media.DATA };
Cursor cursor = activity.managedQuery(contentUri, proj, null, null, null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
Which in turn converted into File:
Uri filePathFromActivity = (Uri) extras.get(Intent.EXTRA_STREAM);
filePathFromActivity = Uri.parse(FileUtil.getRealPathFromUri( (Activity) IntentActivity.this, filePathFromActivity));
File imageFile = new File(filePathFromActivity.getPath());
Gallery returns different URI of media files for Intent.ACTION_GET_CONTENT for different Android Versions
I got simple answer, just encrypt path on basis of android SDK version.
public String getRealPathFromURI(Uri uri) {
if (Build.VERSION.SDK_INT < 19) {
String[] projection = {MediaStore.Images.Media.DATA};
@SuppressWarnings("deprecation")
Cursor cursor = getActivity().managedQuery(uri, projection, null, null, null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
} else {
String selectedImagePath = null;
String wholeID = DocumentsContract.getDocumentId(uri);
// Split at colon, use second item in the array
String id = wholeID.split(":")[1];
String[] column = {MediaStore.Images.Media.DATA};
// where id is equal to
String sel = MediaStore.Images.Media._ID + "=?";
Cursor cursor = getActivity().getContentResolver().query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, column, sel, new String[]{id}, null);
int columnIndex = cursor.getColumnIndex(column[0]);
if (cursor.moveToFirst()) {
selectedImagePath = cursor.getString(columnIndex);
}
cursor.close();
return selectedImagePath;
}
}
Android open text file to read after Intent.ACTION_GET_CONTENT
Step #1: Delete String filePathName = "WHAT TODO ?";
Step #2: Change LaterFunction(filePathName); to LaterFunction(uri);
Step #3: Change br = new BufferedReader(new FileReader("WHAT TODO ?")); to br = new BufferedReader(new InputStreamReader(getContentResolver().openInputStream(uri));
That is the minimum necessary to address your question.
However, a MIME type of */* will match any type of file, not just text files. Binary files should not be copied using readLine(). If you only want plain text files, use text/plain instead of */*.
Android Gallery on Android 4.4 (KitKat) returns different URI for Intent.ACTION_GET_CONTENT
Try this:
if (Build.VERSION.SDK_INT <19){
Intent intent = new Intent();
intent.setType("image/jpeg");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, getResources().getString(R.string.select_picture)),GALLERY_INTENT_CALLED);
} else {
Intent intent = new Intent(Intent.ACTION_OPEN_DOCUMENT);
intent.addCategory(Intent.CATEGORY_OPENABLE);
intent.setType("image/jpeg");
startActivityForResult(intent, GALLERY_KITKAT_INTENT_CALLED);
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode != Activity.RESULT_OK) return;
if (null == data) return;
Uri originalUri = null;
if (requestCode == GALLERY_INTENT_CALLED) {
originalUri = data.getData();
} else if (requestCode == GALLERY_KITKAT_INTENT_CALLED) {
originalUri = data.getData();
final int takeFlags = data.getFlags()
& (Intent.FLAG_GRANT_READ_URI_PERMISSION
| Intent.FLAG_GRANT_WRITE_URI_PERMISSION);
// Check for the freshest data.
getContentResolver().takePersistableUriPermission(originalUri, takeFlags);
}
loadSomeStreamAsynkTask(originalUri);
}
Probably need
@SuppressLint("NewApi")
for
takePersistableUriPermission
