I am trying to open and read file that was been saved either on the sdCard or on the google drive or on the internal memory by using the android file chooser ...
after I successfully chosen the file and I get the file path as shown on the following code when I try to read it it keeps throwing me the that the file does not exist / no such file or directory ....
my code:
public class MainActivity extends AppCompatActivity {
private static final int CHOOSE_FILE_REQUEST_CODE = 1;
String[] ids;
TextView textView;
Button btnImport;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
textView = (TextView) findViewById(R.id.text_view);
btnImport = (Button) findViewById(R.id.btn_import);
btnImport.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.addCategory(Intent.CATEGORY_OPENABLE);
intent.setType("*/*");
Intent i = Intent.createChooser(intent, "File");
startActivityForResult(i, CHOOSE_FILE_REQUEST_CODE);
}
});
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (data == null) {
return;
}
switch (requestCode) {
case 1:
if (resultCode == RESULT_OK) {
String path = data.getData().getPath();
String url = data.getData().getPath();
File file = new File(url);
Log.i("***", path);
// InputStream inputStream = getResources().openRawResource(R.raw.sample);
InputStream inputStream = null ;
BufferedReader bufferedReader = null;
try {
inputStream = new FileInputStream(file);
bufferedReader = new BufferedReader(new InputStreamReader(inputStream));
String csvLine;
StringBuffer stringBuffer = new StringBuffer();
while ((csvLine = bufferedReader.readLine()) != null) {
ids = csvLine.split(",");
for (int i = 0; i < ids.length; i++) {
if (i % 19 == 1) {
stringBuffer.append(ids[i]);
stringBuffer.append("\n");
Log.i("***", stringBuffer.toString());
}
textView.setText(stringBuffer.toString());
}
}
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
}
}
}
this is the logs :
