Question

尝试在我的应用中添加声音作为铃声时出现写入错误。我尝试过不同的东西，但不断出现不同的错误。不知道该怎么办。

将mp3作为URL示例传递给声音：

sound = {"http://www.sound.com/file.mp3"}



 public void setRingToneInApp() {

        File k = new File(sound[+position]); // path is a file to /sdcard/media/ringtone
        ContentValues values = new ContentValues();
        values.put(MediaStore.MediaColumns.DATA, k.getAbsolutePath());
        values.put(MediaStore.MediaColumns.TITLE, "My Song title");
        values.put(MediaStore.MediaColumns.SIZE, 215454);
        values.put(MediaStore.MediaColumns.MIME_TYPE, "audio/mp3");
        values.put(MediaStore.Audio.Media.ARTIST, "Annoying Sound");
        values.put(MediaStore.Audio.Media.DURATION, 230);
        values.put(MediaStore.Audio.Media.IS_RINGTONE, true);
        values.put(MediaStore.Audio.Media.IS_NOTIFICATION, false);
        values.put(MediaStore.Audio.Media.IS_ALARM, false);
        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);

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
            Log.i("", "Build.VERSION.SDK_INT=" + Build.VERSION.SDK_INT);
            if (Settings.System.canWrite(context)) {
                Log.i("", "Settings.System.canWrite=true");
                RingtoneManager.setActualDefaultRingtoneUri(context.getApplicationContext(), RingtoneManager.TYPE_RINGTONE, newUri);
            } else {
                Log.i("", "try to get write permissin from user");
                RingtoneManager.setActualDefaultRingtoneUri(context.getApplicationContext(), RingtoneManager.TYPE_RINGTONE, newUri);
            }
        }
    }

logcat显示：

编辑：

我在清单中也有这个：

 <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
    <uses-permission-sdk-23 android:name="android.permission.WRITE_SETTINGS" />

Answer 1

首先是关于安全性的例外情况。

使用Setting.System.canWrite()

首先它应该出现在清单文件中。

第二你应该根据你是否被允许写作canWrite()来回复真或假。

如果false返回InputStream input = new BufferedInputStream(url.openStream()); File sdCard = Environment.getExternalStorageDirectory(); File dir = new File (sdCard.getAbsolutePath() + "/myfoldername/dir3"); dir.mkdirs(); File file = new File(dir, myringtonename + ".mp3"); FileOutputStream output = new FileOutputStream(file); setringtone(file);开始AWS documentation on creating custom AMIs for Elastic Beanstalk，则为第三。在这种情况下，用户将允许写入。

现在，对于铃声，您可以将铃声保存在手机记忆库中，然后可以将其设为铃声。具体如下：

private void setringtone(File file) {
            ContentValues values = new ContentValues();
            values.put(MediaStore.MediaColumns.DATA, file.getAbsolutePath());
            values.put(MediaStore.MediaColumns.TITLE, "My Song title");
            values.put(MediaStore.MediaColumns.SIZE, 215454);
            values.put(MediaStore.MediaColumns.MIME_TYPE, "audio/mp3");
            values.put(MediaStore.Audio.Media.ARTIST, "You");
            values.put(MediaStore.Audio.Media.DURATION, 230);
            values.put(MediaStore.Audio.Media.IS_RINGTONE, true);
            values.put(MediaStore.Audio.Media.IS_NOTIFICATION, false);
            values.put(MediaStore.Audio.Media.IS_ALARM, false);
            values.put(MediaStore.Audio.Media.IS_MUSIC, false);
            Uri uri = MediaStore.Audio.Media.getContentUriForPath(file.getAbsolutePath());
            Uri newUri = getContentResolver().insert(uri, values);
 RingtoneManager.setActualDefaultRingtoneUri(getApplicationContext(),RingtoneManager.TYPE_RINGTONE,newUri);

        }

然后你可以调用你的功能将其设置为铃声

#cup { z-index: -1; }
/* or */
#registration_form { position: relative; }

我希望它有所帮助。
