Android: save sound as ringtone / SQLiteConstraintException

问题

I'm trying to save a sound as a ringtone in Android using this code. It works like a charm but will fail if I try to save a ringtone that has already been inserted.

A "SQLiteConstraintException" occurs while saving but I'm not able to catch the exception, in fact, I can't catch any execption.

Here's the part of my code:

Uri uri = MediaStore.Audio.Media.getContentUriForPath(k.getAbsolutePath());

try {
  this.getContentResolver().insert(uri, values);
} catch (SQLiteConstraintException e) {
  Log.e("error", e.getMessage());
} catch (SQLiteException e) {
  Log.e("error", e.getMessage());
} catch (Exception e) {
  Log.e("error", e.getMessage());
}

So I'm trying to actually catch any possible exception, but none is caught.

This is the LogCat:

I found a workaround: I check if the soundfile exists before I call the .insert-method (and don't call it, if the file's already there), but I'd really like to understand why no exception is caught. Hope anybody can help me out.

Kind regards, Select0r

It is not caught because the exception is not in your code. It is not even in your process. It is in the process of the MediaStore content provider.

回答2:

I was having the same issue....it's because you don't have this permission in your manifest

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

Also, if you're using that tutorial, make sure you have this in your manifest as well...

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

I spent a good half an hour or so trying to figure out why the code wasn't working. I actually removed the try/catch just to see what type of error it would throw in the logcat, and it told me I was missing those permissions.
