我不知道这里有什么问题。我正在使用以下代码：
@Override
protected void onHandleIntent(Intent intent) {
Intent broadcastIntent = new Intent();
int count;
String full_url = URL + intent.getStringExtra(VIDEOS);
// TODO Auto-generated method stub
try {
URL url = new URL(full_url);
URLConnection conexion = url.openConnection();
conexion.connect();
int lenghtOfFile = conexion.getContentLength();
Log.d("ANDRO_ASYNC", "Lenght of file: " + lenghtOfFile);
InputStream input = new BufferedInputStream(url.openStream());
OutputStream output = new FileOutputStream(new File(root.getPath(),intent.getStringExtra(VIDEOS)));
byte data[] = new byte[1024];
long total = 0;
contentView.setTextViewText(R.id.status_text,"Downloading " + intent.getStringExtra(VIDEOS));
while ((count = input.read(data)) != -1) {
total += count;
notification.contentView.setProgressBar(R.id.status_progress, 100,(int)((total*100)/lenghtOfFile), false);
notificationManager.notify(1,notification);
Log.e("INTENT-FLAGS:","Percentage Downloaded: " + (int)((total*100)/lenghtOfFile) + " file: " + intent.getStringExtra(VIDEOS));
output.write(data, 0, count);
}
output.flush();
output.close();
input.close();
} catch (Exception e) {}
}
缓冲区很小，所以不应该是一个问题。下载第一个文件，大约140 KB，第二个文件开始下载，然后最终崩溃整个应用程序和整个电话会话（从电话中取出）。另一件事是使用带有进度条的通知栏，当文件开始下载时，它会冻结通知栏。
这是它开始崩溃的地方：
