ここでは、json
からデータを取得するのに非常に時間がかかります。削除して再度インストールすると、1分以内にjson
が表示されます。json
のボタンをもう一度クリックすると、時間がかかり、データが取得されませんlistview
これが私の例外コードです

Java file:にjsonコードがあります
progress = ProgressDialog.show(MainActivity.this, "dialog title", "dialog message", true);
Toast.makeText(MainActivity.this, "ok", Toast.LENGTH_LONG).show();
if (isNetworkAvailable()) {
String url = "ConstantValue.URL";
RequestBody formBody = new FormBody.Builder()
.add(employeeId, value)
.build();
try {
post(url, formBody, new Callback() {
@Override
public void onFailure(Call call, IOException e) {
Log.e("JSONDemo", "IOException", e);
}
@Override
public void onResponse(final Call call, final Response response) throws IOException {
String JSON = response.body().string();
Log.e("res", " " + JSON);
try {
JSONObject jsonObj = new JSONObject(JSON);
JSONArray resultarr = jsonObj.getJSONArray("result");
final JSONArray resultarr1 = jsonObj.getJSONArray("result1");
if (resultarr1.length() == 0) {
showAlertDialog("API", "Data Unavailable");
} else {
for (int i = 0; i < resultarr1.length(); i++) {
Employee emp = new Employee();
JSONObject result1obj = resultarr1.getJSONObject(i);
String result1Id = result1obj.getString("ID");
String result1Name = result1obj.getString("NAME");
String result1Value = result1obj.getString("VALUE");
Log.e("result", " " + result1Name);
Log.e("result", " " + result1Value);
Log.e("result", " " + result1Id);
emp.setValue(result1Value);
emp.setName(result1Name);
emp.setId(result1Id);
arr.add(emp);
}
}
runOnUiThread(new Runnable() {
@Override
public void run() {
// you can access all the UI componenet
if (progress.isShowing())
progress.dismiss();
cu.notifyDataSetChanged();
}
});
} catch (Exception e) {
Log.e("JSONDemo", "onResponse", e);
showAlertDialog("API","Something went wrong");
}
}
});
} catch (Exception e) {
Log.e("JSONDemo", "Post Exception", e);
}
} else {
Toast.makeText(MainActivity.this, "Internet not available", Toast.LENGTH_LONG).show();
}
}
その他のコード:
private final OkHttpClient client = new OkHttpClient();
Call post(String url, RequestBody formBody, Callback callback) throws IOException {
Request request = new Request.Builder()
.url(url)
.post(formBody)
.build();
client.setConnectTimeout(30, TimeUnit.SECONDS);
client.setReadTimeout(30, TimeUnit.SECONDS);
client.setWriteTimeout(30, TimeUnit.SECONDS);
Call call = client.newCall(request);
call.enqueue(callback);
return call;
}
IOExceptiojava.net.SocketTimeoutExceptionが次の条件で発生しています。
OkHttpClient client = new OkHttpClient();
client.setConnectTimeout(30, TimeUnit.SECONDS);
client.setReadTimeout(30, TimeUnit.SECONDS);
client.setWriteTimeout(30, TimeUnit.SECONDS);
Okhttp3を使用している場合は、ビルダーを使用して実行する必要があります。
OkHttpClient.Builder builder = new OkHttpClient.Builder();
builder.connectTimeout(30, TimeUnit.SECONDS);
builder.readTimeout(30, TimeUnit.SECONDS);
builder.writeTimeout(30, TimeUnit.SECONDS);
client = builder.build();
