Android SDcard Permissopn denied while writing a file?

Question

In my application, while writing a file sdcard it shows Permission denied. But i give permission in sdcard. Please help?

Writing file code:

 File sdcard = Environment.getExternalStorageDirectory();
            File f = new File(sdcard, "/abc.txt");
            if (f.exists()) {
                f.delete();
            }

Manifest :

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

Thanks in advance!!

Answer 1

it requires permissions in manifest file, add this line to your manifest file

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/> 

Look at this Question Android saving file to external storage

You need add use-permission in AndroidManifest file, and you should better check if you can r/w the file use canWrite() canRead() before use it.

Answer 4

I think your SD card is currently connect to your computer so it will cause problem. I get in this situation before. You need to unmount sd card first
