I have a problem
I created my progress dialog
dialog = new ProgressDialog(InstallerActivity.this);
I have 12 apk files in my assets folder. I am trying to copy all 12 assets to sdcard with this function
private void CopyAssets() {
AssetManager assetManager = getAssets();
String[] files = null;
String[] files2 = null;
try {
files2 = assetManager.list("");
List<String> sb = new ArrayList();
for (String curfile : files2) {
if (curfile.endsWith("apk")) {
sb.add(curfile);
}
}
files = sb.toArray(new String[sb.size()]);
} catch (IOException e) {
Log.e("tag", e.getMessage());
}
dialog.setMax(files.length);
dialog.setProgress(0);
for(String filename : files) {
InputStream in = null;
OutputStream out = null;
try {
in = assetManager.open(filename);
out = new FileOutputStream(externalPath + "/" + appsdir + "/" + filename);
copyFile(in, out);
in.close();
in = null;
out.flush();
out.close();
dialog.incrementProgressBy(1);
out = null;
} catch(Exception e) {
Log.e("tag", e.getMessage());
}
}
}
private void copyFile(InputStream in, OutputStream out) throws IOException {
byte[] buffer = new byte[1024];
int read;
while((read = in.read(buffer)) != -1){
out.write(buffer, 0, read);
}
}
But my app always crashes on 10 files, with an error: Window leaked. If I delete Log.e, it wont crash, but still copy only 10 files, not 12!
After googling I found that I need to use dialog.dismiss(), but I dont want to dissmiss it now, it is needed to show progress of 2 more elements!

Edit:
Seems like this is not a progressdialog issue. Fixed log.e line and got new error:

Why it cant copy after 10th element from assets?
Thanks
Excuse me for that misunderstanding.
The problem was with assets. I folowed this blog post http://ponystyle.com/blog/2010/03/26/dealing-with-asset-compression-in-android-apps/ and renamed files to .jpg. now it works.
Seems that it is an android bug that does-not allow to handle assets-files bigger than 4mb.
Thanks everyone for you help!
