我有两个问题:铃声设置了Android 2.3的沉默,但适用于4.0.3
当我打电话给我的
saveas(ressound);
的是Android 4.0.3设备上(由stealthcopter.com启发)铃声作为铃声很好地激活,但在2.3.3设备上,选定的铃声是无声的。我的代码在哪里出错?我想知道的第二件事是如何删除文件。更重要的是,如何将其从媒体商店中解脱出来,如果我从sd中删除它,它会自动发生吗?
UPDATE:
添加的代码删除整个文件夹加内容,做工不错,干净! (见下文)
尝试调用此代码时,我按下按钮:
sendBroadcast(new Intent(Intent.ACTION_MEDIA_MOUNTED, Uri.parse("file://" + Environment.getExternalStorageDirectory())));
但它不会清理出mediastore,它与重新启动。 我也尝试了开发工具内的媒体扫描,但这不起作用。他们提到有些应用程序需要重新启动,但是如何重新启动负责显示可用铃声列表的服务,而无需重新启动整个设备?
变量:
String soundname;
int ressound;
int savetype;
String path="/sdcard/mysounds/";
savetype = RingtoneManager.TYPE_RINGTONE;
ressound = R.raw.sound1;
soundname = "sound1";
另存为(ressound);
//save as
public boolean saveas(int ressound){
byte[] buffer=null;
InputStream fIn = getBaseContext().getResources().openRawResource(ressound);
int size=0;
try {
size = fIn.available();
buffer = new byte[size];
fIn.read(buffer);
fIn.close();
} catch (IOException e) {
return false;
}
String filename= soundname +".mp3";
boolean exists = (new File(path)).exists();
if (!exists){new File(path).mkdirs();}
FileOutputStream save;
try {
save = new FileOutputStream(path+filename);
save.write(buffer);
save.flush();
save.close();
} catch (FileNotFoundException e) {
return false;
} catch (IOException e) {
return false;
}
sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, Uri.parse("file://"+path+filename)));
File k = new File(path, filename);
ContentValues values = new ContentValues();
values.put(MediaStore.MediaColumns.DATA, k.getAbsolutePath());
values.put(MediaStore.MediaColumns.TITLE, soundname);
values.put(MediaStore.MediaColumns.MIME_TYPE, "audio/mp3");
values.put(MediaStore.Audio.Media.ARTIST, "Elvis");
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);
//Insert it into the database
Uri newUri = this.getContentResolver().insert(MediaStore.Audio.Media.getContentUriForPath(k.getAbsolutePath()), values);
// set as ringtone
RingtoneManager.setActualDefaultRingtoneUri(this, savetype, newUri);
return true;
}
delete();
public void delete() {
File a = new File(path, "sound1.mp3");
a.delete();
File b = new File(path, "sound2.mp3");
b.delete();
}
deleteFiles(String path);
public static void deleteFiles(String path) {
File file = new File(path);
if (file.exists()) {
String deleteCmd = "rm -r " + path;
Runtime runtime = Runtime.getRuntime();
try {
runtime.exec(deleteCmd);
} catch (IOException e) { }
}
}
目前市场上有更多的应用程序有这个问题,我不知道它是否可以修复? – John 2012-04-12 19:53:58
也许是因为它覆盖,如果文件已经到位。不知道如何修复.... – John 2012-04-12 19:56:27
我做了删除功能,其中整个地图加内容被删除。因此,我检查了上述假设,没有运气。 – John 2012-04-12 19:59:33
