I’m making a stock count app and it needs to import a txt and export the same with the quantities read in the count, the problem is that searching found the library android studio to load the file from storage:
private static final int READ_REQUEST_CODE = 42;
/**
* Fires an intent to spin up the "file chooser" UI and select an image.
*/
public void performFileSearch() {
// ACTION_OPEN_DOCUMENT is the intent to choose a file via the system's file
// browser.
Intent intent = new Intent(Intent.ACTION_OPEN_DOCUMENT);
// Filter to only show results that can be "opened", such as a
// file (as opposed to a list of contacts or timezones)
intent.addCategory(Intent.CATEGORY_OPENABLE);
// Filter to show only images, using the image MIME data type.
// If one wanted to search for ogg vorbis files, the type would be "audio/ogg".
// To search for all documents available via installed storage providers,
// it would be "*/*".
intent.setType("text/plain");
startActivityForResult(intent, READ_REQUEST_CODE);
}
in onActivityResult this way
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
IntentResult result = IntentIntegrator.parseActivityResult(requestCode, resultCode, data);
if (result != null){
String barcode = result.getContents();
if (barcode != null && !"".equals(barcode)){
createFragment.setBarCode(barcode);
}
} else {
super.onActivityResult(requestCode, resultCode, data);
}
// The ACTION_OPEN_DOCUMENT intent was sent with the request code
// READ_REQUEST_CODE. If the request code seen here doesn't match, it's the
// response to some other intent, and the code below shouldn't run at all.
if (requestCode == READ_REQUEST_CODE && resultCode == Activity.RESULT_OK) {
// The document selected by the user won't be returned in the intent.
// Instead, a URI to that document will be contained in the return intent
// provided to this method as a parameter.
// Pull that URI using resultData.getData().
Uri uri = null;
if (data != null) {
uri = data.getData();
Log.i("resultado", "Uri: " + uri.toString());
File file= new File(uri.getPath());
String conteudoArquivo = file.getName();
salvarArquivo(conteudoArquivo);
}
}
}
I am trying to load the txt file in an array that is loaded on the home screen, I have tried it in several ways and could not. By clicking the button it opens the storage and I can search and load the txt in the variableUri after that I cannot read the file and load in the Array
Where is txt stored? I recently created a library that handles incoming Uri via result. Handlepathoz, if you are interested in using it. The output of the methods I created return the actual file path string, with it it is possible to access the desired file. Inside the repository there are also examples of using the library.
