我找到this帮助，我正在测试它，当我完成时，如果有效，我会来这里写
我用一个循环来测试它
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,//tryies 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小时，没有任何错误
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
Teste与RequestQueue queue = Volley.newRequestQueue(MyActivity.this);多次通话
例如
//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,//tryies 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;
Erro，475次

你不能多次拨打newRequestQueue ...
您将收到out memory或OOM错误的错误。
更多关于参考或信息的链接：
1.- Out of memory error when use volley library
2.- Volley give me Out of memory exception after I make a lot of request with big amount of data
3.- Volley slow and causing memory leak
4.- Volley framewok request keeps objects in memory

答案 2 :(得分：1)
当您尝试将大数据加载到超出可用RAM的应用程序内存中时，会发生OutOfMemoryError。我现在不知道你在使用凌空的是什么，但是尝试为volley see here禁用缓存或者不立即加载大文件或尝试压缩文件。如果您提供有关您要实现的内容的更多详细信息以及导致错误的代码部分，将会有所帮助。

尝试读取标题时会抛出此标题，标题应该相对较小。另请注意，DiskBasedCache大小仅为5MB。
