Making new file in android
Question
I have a problem, I want to set a ringtone inside my main acivity, I read this tutorial: http://androidgenuine.com/?tag=set-as-ringtone-android , but function save is not working, to be more specific I can't create a file, function is returning false. I write again only a part with creating new File but even this part is not working, here is the code, what's wrong (it;s returning false and non file was created) ?
public boolean save2(int ressound){
String path="/sdcard/sounds/";
String filename="ring.mp3";
byte[] buffer = null;
FileOutputStream save;
InputStream fIn = getBaseContext().getResources().openRawResource(ressound);
int size=0;
try {
size=fIn.available();
buffer = new byte[size];
fIn.read(buffer);
fIn.close();
} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
try {
save = new FileOutputStream(path+filename);
save.write(buffer);
save.flush();
save.close();
return true;
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
return false;
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
return false;
}
}
Thanks for your help
Solution
I can only guess that directory you specified might not exist or that you do not have the appropriate permission set in your manifest.
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
You should be constructing it with the following from documentation found at
http://developer.android.com/reference/android/os/Environment.html#getExternalStorageDirectory()
File path = Environment.getExternalStoragePublicDirectory(
Environment.DIRECTORY_PICTURES);
File file = new File(path, "DemoPicture.jpg");
// Make sure the Pictures directory exists.
path.mkdirs();
You also must check if the external storage is even mounted.
String state = Environment.getExternalStorageState();
if (Environment.MEDIA_MOUNTED.equals(state)) {
mExternalStorageAvailable = mExternalStorageWriteable = true;
} else if (Environment.MEDIA_MOUNTED_READ_ONLY.equals(state)) {
mExternalStorageAvailable = true;
mExternalStorageWriteable = false;
} else {
mExternalStorageAvailable = mExternalStorageWriteable = false;
}
