Through my application the user can choose a file from the filemanager and process the choosen file ( Example: A PDF document ) for other steps like printing or to email.
To do this I used the below code to display the intent, from which the user can choose a file from file-manager option.
protected void showFileChooser(String title, String type) {
Log.i(TAG, "FileChooserActivity showFileChooser(title,type)");
if (TextUtils.isEmpty(title)) title = getString(R.string.select_file);
if (TextUtils.isEmpty(type)) type = "*/*";
// Implicitly allow the user to select a particular kind of data
final Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
// Specify the MIME data type filter (Must be lower case)
intent.setType(type.toLowerCase());
// Only return URIs that can be opened with ContentResolver
intent.addCategory(Intent.CATEGORY_OPENABLE);
// Display intent chooser
try {
startActivityForResult(
Intent.createChooser(intent, title),6384);
} catch (android.content.ActivityNotFoundException e) {
Log.i(TAG,"FileChooserActivity showFileChooser(title,type) Exception" +Log.getStackTraceString(e));
onFileError(e);
}
}
Problem in Android Kitkat version ( 4.4 ) :
Using the above code , I can access all files from the file manager ( i.e., both sub folder's and root folder) in android 4.3 and all android versions except Android 4.4.
In Android 4.4 , I can access files from the root folder, where as I cant access the files from the subfolders. I get java.io.FileNotFoundException as exception.
Note: I installed Astro File Manager and through this I can access both root and sub-folders in Android 4.4. But I cant access the sub-folder files through Androids default file manager.
