In one of my apps, I want to add the possibility for the user to set a ringtone with a sound from my res/raw folder.
As I had no idea about how to do it, I found a piece of code on this website.
I created clone of my project and I want to test this piece of code before adapting it to my app.
here is the code :
File file = new File(Environment.getExternalStorageDirectory(),
"/myRingtonFolder/Audio/");
if (!file.exists()) {
file.mkdirs();
}
String path = Environment.getExternalStorageDirectory()
.getAbsolutePath() + "/myRingtonFolder/Audio/";
File f = new File(path + "/"+ name + ".mp3");
Uri mUri = Uri.parse("android.resource://"
+ context.getPackageName() + "/raw/" + name);
ContentResolver mCr = context.getContentResolver();
AssetFileDescriptor soundFile;
try {
soundFile = mCr.openAssetFileDescriptor(mUri, "r");
} catch (FileNotFoundException e) {
soundFile = null;
}
try {
byte[] readData = new byte[1024];
FileInputStream fis = soundFile.createInputStream();
FileOutputStream fos = new FileOutputStream(f);
int i = fis.read(readData);
while (i != -1) {
fos.write(readData, 0, i);
i = fis.read(readData);
}
fos.close();
} catch (IOException io) {
}
ContentValues values = new ContentValues();
values.put(MediaStore.MediaColumns.DATA, f.getAbsolutePath());
values.put(MediaStore.MediaColumns.TITLE, name);
values.put(MediaStore.MediaColumns.MIME_TYPE, "audio/mp3");
values.put(MediaStore.MediaColumns.SIZE, f.length());
values.put(MediaStore.Audio.Media.ARTIST, R.string.app_name);
values.put(MediaStore.Audio.Media.IS_RINGTONE, true);
values.put(MediaStore.Audio.Media.IS_NOTIFICATION, true);
values.put(MediaStore.Audio.Media.IS_ALARM, true);
values.put(MediaStore.Audio.Media.IS_MUSIC, true);
Uri uri = MediaStore.Audio.Media.getContentUriForPath(f
.getAbsolutePath());
Uri newUri = mCr.insert(uri, values); //errror here
try {
RingtoneManager.setActualDefaultRingtoneUri(context,
RingtoneManager.TYPE_RINGTONE, newUri);
Settings.System.putString(mCr, Settings.System.RINGTONE,
newUri.toString());
} catch (Throwable t) {
}
The problem is I get this error :
FATAL EXCEPTION: main

I know that the problem come from this line : Uri newUri = mCr.insert(uri, values);. I tried to add the permission in my manifest but I still get this error.
Can you help me to find the problem please.
