Question

我正在尝试使用它：

RingtoneManager.setActualDefaultRingtoneUri(this, RingtoneManager.TYPE_RINGTONE, newUri);

...设置默认铃声。类似SecurtyException的例外情况就会消失。

我看了看这个：

RingtoneManager.setActualDefaultRingtoneUri(this, RingtoneManager.TYPE_RINGTONE, newUri);

...看看是否有任何权限可以在menefest文件中设置与铃声相对应的内容，找不到任何内容。

以下是我的代码：

// make it a ring tone
    void   MakeRingtune( String name)
    {

    File newSoundFile = new File("/sdcard/", "myringtone.oog");

    String strUri = "android.resource://"+getPackageName()+  "/" + "raw/"+name;
    Uri mUri = Uri.parse(strUri);

    ContentResolver mCr = getContentResolver();
    AssetFileDescriptor soundFile;
    try {
           soundFile= mCr.openAssetFileDescriptor(mUri, "r");
       } catch (FileNotFoundException e) {
           MessageBox("Ringtone Manager ","System Error cannot add ringtone ");
           return;  
       }

       try {
          byte[] readData = new byte[1024];
          FileInputStream fis = soundFile.createInputStream();
          FileOutputStream fos = new FileOutputStream(newSoundFile);
          int i = fis.read(readData);

          while (i != -1) {
            fos.write(readData, 0, i);
            i = fis.read(readData);
          }

          fos.close();
       } catch (IOException io) {
           MessageBox("Ringtone Manager ","Could not copy Ringtone, may be due to no sd card");
           return;
       }

           MessageBox("Ringtone Manager ","Could not set as your default ringtone ");
           return;
       }

“android.permission.WRITE_SETTINGS”是您需要的。

尝试设置默认铃声会获得SecurityException
