应用程序在模拟器上工作但不是真正的 phone，同时从存储（专辑艺术）设置位图图像
app works on the emulator but not real phone while setting bitmap images from the storage(Album arts)
我在图像视图上设置专辑封面（位图图像）时遇到问题，但令人惊讶的是它只在我的 phone 上崩溃，而 运行 在模拟器上完全正常。我不知道问题是什么，因为我无法获得崩溃报告。但我很确定问题仅出在这些行上：-
try {
MediaMetadataRetriever mmr = new MediaMetadataRetriever();
mmr.setDataSource(songPath);
byte[] data = mmr.getEmbeddedPicture();
bitmap = BitmapFactory.decodeByteArray(data, 0, data.length);
} catch (NullPointerException e) {
bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.round); //Converting resource image into bitmap
e.printStackTrace();
}
因为，删除这些行会使它 运行 完美..
从外部存储中检索数据的完整方法是：
public ArrayList<Data> GetPlaylist() {
Bitmap bitmap=null;
ContentResolver contentResolver = getActivity().getContentResolver();
Uri songUri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
Cursor songCursor = contentResolver.query(songUri, null, null, null, MediaStore.Audio.Media.TITLE + " ASC");
if (songCursor != null && songCursor.moveToFirst()) {
do {
int songId = songCursor.getInt(songCursor.getColumnIndex(MediaStore.Audio.Media._ID));
String songTitle = songCursor.getString(songCursor.getColumnIndex(MediaStore.Audio.Media.TITLE));
String songArtist = songCursor.getString(songCursor.getColumnIndex(MediaStore.Audio.Media.ARTIST));
String songPath = songCursor.getString(songCursor.getColumnIndex(MediaStore.Audio.Media.DATA));
try {
MediaMetadataRetriever mmr = new MediaMetadataRetriever();
mmr.setDataSource(songPath);
byte[] data = mmr.getEmbeddedPicture();
bitmap = BitmapFactory.decodeByteArray(data, 0, data.length);
} catch (NullPointerException e) {
bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.round); //Converting resource image into bitmap
e.printStackTrace();
}
songList.add(new Data(songTitle, songArtist,bitmap));
}
while (songCursor.moveToNext());
}
songCursor.close();
return songList;
}
