我在循环到 stringbuilder 的 asynctask 中出现内存不足错误。我的目标是使用它从服务器下载图像并存储在我的 sd 卡中。我的代码如下:
HttpClient httpclient = new DefaultHttpClient();
httpclient.getParams().setParameter(CoreProtocolPNames.PROTOCOL_VERSION, HttpVersion.HTTP_1_1);
HttpPost httppost = new HttpPost(severPath);
httppost.setEntity(params[0]);
System.out.println("executing request " + httppost.getRequestLine());
HttpResponse response = null;
try {
response = httpclient.execute(httppost);
} catch (ClientProtocolException e6) {
// TODO Auto-generated catch block
e6.printStackTrace();
} catch (IOException e6) {
// TODO Auto-generated catch block
e6.printStackTrace();
}
String output;
System.out.println("Output from Server .... \n");
BufferedReader br = null;
try {
br = new BufferedReader(
new InputStreamReader((response.getEntity().getContent())));
} catch (IllegalStateException e5) {
// TODO Auto-generated catch block
e5.printStackTrace();
} catch (IOException e5) {
// TODO Auto-generated catch block
e5.printStackTrace();
}
OutputStreamWriter outputStreamWriter = null;
try {
outputStreamWriter = new OutputStreamWriter(context.openFileOutput("LargeImages.txt", context.MODE_PRIVATE));
} catch (FileNotFoundException e6) {
// TODO Auto-generated catch block
e6.printStackTrace();
}
int i = 0;
StringBuilder builder = new StringBuilder();
String Result = "";
try {
for (String line = null; (line = br.readLine()) != null ; ) {
builder.append(line.toString());
}
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
outputStreamWriter.close();
我正在摆脱内存分配错误。请帮忙。我尝试了很多方法,但也没有得到正确的方法。
