Question

我使用以下代码为各个联系人设置铃声

String contact_number = "MOBILE_NUMBER";
        Uri lookupUri = Uri.withAppendedPath(ContactsContract.PhoneLookup.CONTENT_FILTER_URI, contact_number);

        // The columns used for `Contacts.getLookupUri`
        String[] projection = new String[]{
                ContactsContract.Contacts._ID, ContactsContract.Contacts.LOOKUP_KEY
        };

        // Build your Cursor
        Cursor data = getContentResolver().query(lookupUri, projection, null, null, null);

        if (data != null && data.moveToFirst()) {
            data.moveToFirst();
            try {
                // Get the contact lookup Uri
                long contactId = data.getLong(0);
                String lookupKey = data.getString(1);
                Uri contactUri = ContactsContract.Contacts.getLookupUri(contactId, lookupKey);
                if (contactUri == null) {
                    // Invalid arguments
                    return;
                }

                String ringtoneUri = Environment.getExternalStorageDirectory().getAbsolutePath() + "/Test";
                File filePath = new File(ringtoneUri, "Bhar.MP3");

                Log.e("filePath", filePath.toString());

                String value = Uri.fromFile(filePath).toString();

                // Apply the custom ringtone
                ContentValues values = new ContentValues();
                values.put(ContactsContract.Data.RAW_CONTACT_ID, contactId);
                values.put(ContactsContract.Contacts.CUSTOM_RINGTONE, value);
                getContentResolver().update(contactUri, values, null, null);


            } finally {
                // Don't forget to close your Cursor
                data.close();
            }
        }

此代码适用于大多数设备，但它在Samsung j5（Android版本6.0.1）中无效，我也检查了相同版本的设备（如Moto G3），在这些设备中它＆＃39;工作正常。

注意：

我提供了与Marshmallow相关的所有权限
当我将铃声分配给J5手机时。它将铃声名称分配给特定联系人，但它没有播放指定的铃声。有关了解，请查看附件

关注this question我尝试检查媒体URI而不是文件URI。看起来像某些（甚至大多数）设备，不喜欢设置实际文件而不先为文件创建铃声媒体条目。

这是我的“铃声下载”代码，适用于所有代码，后面是对某些代码无效的代码：

URLConnection cn = new URL（mediaUrl）.openConnection（）;

        cn.connect();
        InputStream stream = cn.getInputStream();

        final File dir = new File(Environment.getExternalStorageDirectory().toString() + donloadedFilesDir);
        dir.mkdirs(); //create folders where write files
        final File file = new File(dir, getFileName(mediaUrl));

        FileOutputStream out = new FileOutputStream(file);
        byte buffer[] = new byte[1024];
        int dataSize;
        while ((dataSize = stream.read(buffer)) != -1) {
            out.write(buffer, 0, dataSize);
        }

        stream.close();
        out.flush();
        out.close();
        //Getting the file again to have the size after write
        File k = new File(dir, getFileName(mediaUrl));

        ContentValues values = new ContentValues();
        values.put(MediaStore.MediaColumns.DATA, k.getAbsolutePath());
        values.put(MediaStore.MediaColumns.TITLE, "vCallRingtone");
        values.put(MediaStore.MediaColumns.MIME_TYPE, "audio/" + getFileExtention(mediaUrl));
        values.put(MediaStore.MediaColumns.SIZE, k.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, false);

        Uri uri = MediaStore.Audio.Media.getContentUriForPath(k.getAbsolutePath());
        context.getContentResolver().delete(uri, MediaStore.MediaColumns.DATA + "=\"" + k.getAbsolutePath() + "\"", null);
        Uri newUri = context.getContentResolver().insert(uri, values);

        return newUri.toString();

以下是旧代码无效：

URLConnection cn = new URL(mediaUrl).openConnection();

        cn.connect();
        InputStream stream = cn.getInputStream();

        final File dir = new File(Environment.getExternalStorageDirectory().toString() + donloadedFilesDir);
        dir.mkdirs(); //create folders where write files
        final File file = new File(dir, getFileName(mediaUrl));

        FileOutputStream out = new FileOutputStream(file);
        byte buffer[] = new byte[1024];
        int dataSize;
        while ((dataSize = stream.read(buffer)) != -1) {
            out.write(buffer, 0, dataSize);
        }

        stream.close();
        out.flush();
        out.close();

        return Uri.fromFile(file).toString();

不在某些设备中分配铃声
