推荐答案
我发现了此帮助，我正在测试完成后，我会来这里写作，如果它能奏效
I found this help, I'm testing It, when I finish, I will come here to write if It works
好吧，我以无限的周期对其进行了测试
Well I tested It with an infinite cycle
像这样
//global var
Boolean running = true;
Thread MyThread = new Thread(){//create thread
@Override
public void run() {
RequestQueue queue = Volley.newRequestQueue(MyActivity.this);// start one time no more...
String url = "http://192.168.1.78/testget.php?key=123456789"; // my URL
// Request a string response from the provided URL.
StringRequest stringRequest = new StringRequest(Request.Method.GET, url,
new Response.Listener<String>() {//where request return ...
@Override
public void onResponse(String response) {
System.out.println("Volley response: \"" + response +"\"");
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
System.out.println("There is an error: "+error.getMessage()); // on error, ex: URL bad... internet down, etc..
}
});
stringRequest.setShouldCache(false);// no caching url...
stringRequest.setRetryPolicy(
new DefaultRetryPolicy(
20000,//time to wait for it in this case 20s
20,//tries in case of error
DefaultRetryPolicy.DEFAULT_BACKOFF_MULT
)
);
int i=0;
while(running){
System.out.println("counter: "+i);
i++;
try {
Thread.sleep(500);
} catch (InterruptedException e) {
//e.printStackTrace();
System.out.println("Sleep interrupted");
}
// Add the request to the RequestQueue.
queue.add(stringRequest);
}
System.out.println("onEnd Thread");
}
};
MyThread.start(); // start thread
//in some button declare
running=false;
我测试了 130144次 〜18.07 hr，没有任何错误
I tested it 130144 times ~ 18.07 hr, without any error
System.out: Counter: 130141
System.out: Volley response: "something"
System.out: Counter: 130142
System.out: Volley response: "something"
System.out: Counter: 130143
System.out: Volley response: "something"
System.out: Counter: 130144
呼叫newRequestQueue多次出现错误
使用RequestQueue queue = Volley.newRequestQueue(MyActivity.this);调用多次进行测试
Getting Error with call newRequestQueue more than one time
Test with RequestQueue queue = Volley.newRequestQueue(MyActivity.this); calling more than one time
示例:
//global var
Boolean running = true;
Thread MyThread = new Thread(){//create thread
void getSomethingFromSite(){
RequestQueue queue = Volley.newRequestQueue(MyActivity.this);//calling request more than one time... error you not call more than one time
String url = "http://192.168.1.78/testget.php?key=123456789"; // my url
// Request a string response from the provided URL.
StringRequest stringRequest = new StringRequest(Request.Method.GET, url,
new Response.Listener<String>() {//where request return ...
@Override
public void onResponse(String response) {
System.out.println("Volley response: \"" + response +"\"");
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
System.out.println("There is an error: "+error.getMessage()); // on error, ex: URL bad... internet down, etc..
}
});
stringRequest.setShouldCache(false);// no caching url...
stringRequest.setRetryPolicy(
new DefaultRetryPolicy(
20000,//time to wait for it in this case 20s
20,//tries in case of error
DefaultRetryPolicy.DEFAULT_BACKOFF_MULT
)
);
// Add the request to the RequestQueue.
queue.add(stringRequest);
}
@Override
public void run() {
int i=0;
while(running){
System.out.println("counter: "+i);
i++;
try {
Thread.sleep(500);
} catch (InterruptedException e) {
//e.printStackTrace();
System.out.println("Sleep interrupted");
}
//call volley
getSomethingFromSite();
}
System.out.println("onEnd Thread");
}
};
MyThread.start(); // start thread
//in some button declare
running false;

结论
您最多不会拨打newRequestQueue电话...
您将收到错误out memory或OOM错误.
Conclusion
You do not call newRequestQueue more than one time...
you will get error of out memory or OOM error.
