问题描述
当我从应用程序中设置铃声时,它只能运行一次,但是当再次运行代码时,它将尝试在媒体存储中创建重复条目,这会产生问题.在不为每个声音文件创建单独的唯一文件名的情况下,我想解决此问题.
我在以下答案中找到了此解决方案: http://stackoverflow.com/Questions/4603941/problem-in-setting-audio-file-as-铃声 [ ^ ]
当我在下面的代码中尝试时,出现两个错误.一个是SQLiteException,另一个是RuntimeException,它是由squlite错误引起的,该错误在Java代码之后.
When I set a ringtone from my app, it works once, but when running the code again it tries to create a duplicate entry in the media store, which creates problems. Without creating seperate unique file names for every sound file, I want to fix this problem.
I found this solution posted in an answer here: http://stackoverflow.com/questions/4603941/problem-in-setting-audio-file-as-ringtone[^]
When I try it in my code below, I get two errors. One is an SQLiteException and the other is a RuntimeException which is caused by the squlite error, which is after the Java code.
String TAG = "CFFS";
File dir = new File(Environment.getExternalStorageDirectory()+ "/ringtones"); // Set base DIR where new ringtone will live
dir.mkdirs(); // create if directors don't exist
File outputFile = new File(dir, "College Fight Song.mp3"); // Define out new output file
Uri inURI = null;
try {
inURI = Uri.parse(getIntent().getStringExtra("com.carboni.fightsongs.FILE_RES_ID"));
} catch (Exception e) {
e.printStackTrace();
Log.e(TAG, "Could not get URI " + e);
}
// If we didn't parse a good URI then don't execute the code below
if (inURI != null) {
InputStream in = null;
// Get the input stream
try { in = new BufferedInputStream(this.getContentResolver().openInputStream(inURI)); }
catch (Exception e) { Log.e(TAG, "Exception getting input stream " + e); }
// Get the output stream
OutputStream out = null;
try { out = new FileOutputStream(outputFile); }
catch (Exception e) { Log.e(TAG, "Exception getting output stream " + e); }
// Again, if we don't have 2 good handles then don't try to read/write them
if ((in != null) && (out != null)) {
byte[] buf = new byte[1024]; // Define our buffer size
int bytesRead = 0;
while (bytesRead >= 0) {
try {
bytesRead = in.read(buf, 0, buf.length); // Read max of 1024 bytes
if (bytesRead > 0)
out.write(buf); // Write buffer to new file if we got a good read
} catch (Exception e) {
Log.e(TAG,"Exception reading " + e);
e.printStackTrace();
}
}
}
// Close out handles and proceed
try {
in.close();
out.close();
}
catch (Exception e) { Log.e(TAG, "Exception closing streams " + e); }
ContentValues v = new ContentValues();
v.put(MediaStore.MediaColumns.DATA, outputFile.getAbsolutePath());
v.put(MediaStore.MediaColumns.TITLE, "College Football Fight Song");
v.put(MediaStore.MediaColumns.SIZE, outputFile.length());
v.put(MediaStore.MediaColumns.MIME_TYPE, "audio/mp3");
v.put(MediaStore.Audio.Media.IS_RINGTONE, true);
Uri pURI = MediaStore.Audio.Media.getContentUriForPath(outputFile.getAbsolutePath());
// remove entry every time so we don't get duplicate entries and have a problem setting a 2nd time
getContentResolver().delete(pURI, MediaStore.MediaColumns.DATA + "\"" + outputFile.getAbsolutePath() + "\"", null);
Uri nURI = this.getContentResolver().insert(pURI, v);
Log.i(TAG, "Setting ringtone URI to " + nURI);
// Set ringtone
RingtoneManager.setActualDefaultRingtoneUri(this, RingtoneManager.TYPE_RINGTONE, nURI);
Toast.makeText(this, "Ringtone set", Toast.LENGTH_LONG).show();
错误:
ERROR:
09-03 14:16:08.343: ERROR/DatabaseUtils(11968): android.database.sqlite.SQLiteException: near ""/mnt/sdcard/ringtones/College Fight Song.mp3"": syntax error: , while compiling: DELETE FROM audio_meta WHERE _data"/mnt/sdcard/ringtones/College Fight Song.mp3"
