Arggh! it seems to be a random error, it just happned again a few
times. If I debug and step through it works fine. If i run normally it
fails.
the code fails when builder.create().show(); is called on the
dialogue
Here's the snippets( i'm using the template pattern to build different
loading objects)
in the activity packbuilder is the xml loader, buildJamPacks is the
method i am updating
private void showWelcomeMessage(){
if (mPackBuilder == null) {
mPackBuilder = new JamPackBuilderAssets(this);
mPackBuilder.buildJamPacks();
}
AlertDialog.Builder builder = new AlertDialog.Builder(this);
//builder.setTitle("Please choose a loop pack");
//builder.setIcon(R.drawable.alert_dialog_icon)
builder.setTitle("Welcome to MicroJam!");
builder.setMessage(R.string.instructions);
builder.setPositiveButton("Ok", new
DialogInterface.OnClickListener
() {
public void onClick(DialogInterface dialog, int
whichButton) {
openJamPack(mPackBuilder.getPack(0));//default
pack House 1
}
});
builder.create().show();
}
//Working code:
// Loops through each folder in the root.
// Load the song definition file for each song(default_song.xml)
public void buildJamPacks() {
mJamPacks = new ArrayList<JamPack>();
File[] packs = new File(mRootFolder).listFiles();
int l = packs.length;
for (int i = 0; i < l; i++) {
File pack = packs[i];
File defaultSongFile = new
File(pack.getAbsolutePath() + "/"
+ SONG_FILE_NAME);
if(defaultSongFile.exists()){
Document songXml =
parseSongFile(defaultSongFile);
JamPack JamPack =
buildPackFromXml(pack.getAbsolutePath(),
songXml);
mJamPacks.add(JamPack);
}else{
//TODO: handle this gracefully
}
}
}
protected Document parseSongFile(File file) {
try {
DocumentBuilder docBuilder =
DocumentBuilderFactory.newInstance()
.newDocumentBuilder();
InputStream fis = new FileInputStream(file);
Document songXml = docBuilder.parse(fis);
return songXml;
} catch (FileNotFoundException e) {
//Not working code
public void buildJamPacks() {
mJamPacks = new ArrayList<JamPack>();
AssetManager manager = mCtx.getAssets();
String[] packs;
try {
packs = manager.list(mLoopsDir);
int l = packs.length;
for (int i = 0; i < l; i++) {
String pack = packs[i];
String fullpath = mLoopsDir + "/" + pack ;
Document songXml = parseSongAsset();
JamPack JamPack = buildPackFromXml(fullpath,
songXml);
mJamPacks.add(JamPack);
songXml = null;
}
}
catch(IOException e){
e.printStackTrace();
}
}
protected Document parseSongAsset() {
try {
InputStream filestream = null;
filestream = mCtx.getResources().openRawResource
(R.raw.default_song);
DocumentBuilder docBuilder =
DocumentBuilderFactory.newInstance()
.newDocumentBuilder();
Document songXml = docBuilder.parse(filestream);
return songXml;
} catch (FileNotFoundException e) {
Thanks, please help! this is driving me nuts ;)
