我正在用女巫开发一个应用程序，我需要不断检查数据库更改
因此，我创建了一个处理程序，并在处理程序内部使用了一个函数来检查数据库更改。
它运作良好，但是在我的旧版android 6手机中，该应用在运行2-3分钟后崩溃。
有人有线索吗？
public void search4driver(){
final Handler handler = new Handler();
Runnable runnable = new Runnable() {
@Override
public void run() {
if (driver_id==0) {
****** checktaxiorder(Maghadir.getUserphone());
}else if (driver_id!=0&&condition==0){
condition=1;
driverditails(driver_id);
}else {
}
handler.postDelayed(this, 1000);
// handler.removeCallbacks(Runnable runnable);
}
};
handler.postDelayed(runnable, 10000);
}
我在与********一起显示的行中收到错误
这是我的checktaxiorder函数
public void checktaxiorder(final String phone) {
final StringRequest request = new StringRequest(Request.Method.POST, "http://violet-app.ir/user-taxi-req-check.php",
new Response.Listener<String>() {
@Override
public void onResponse(String response) {
if (response != null) {
try {
JSONArray jsonArray = new JSONArray(response);
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject c = jsonArray.getJSONObject(i);
String rannandeid = c.getString("ranandeid");
driver_id=Integer.parseInt(rannandeid);
}
} catch (Exception e) {
}
} else {
Toast.makeText(getApplicationContext().getApplicationContext(), "no data", Toast.LENGTH_SHORT).show();
}
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
}
}) {
@Override
protected Map<String, String> getParams() throws AuthFailureError {
Map<String, String> params = new HashMap<>();
params.put("phone", phone);
return params;
}
};
******* Volley.newRequestQueue(getApplicationContext()).add(request);
}

最佳答案
问题是我正在为每个请求创建一个新的RequestQueue。
那就是原因。解决方案：
私有RequestQueue requestQueue;
public void uploadData(String s) {
if (requestQueue == null) {
requestQueue = Volley.newRequestQueue(context);
}
}
