无法分配JNI Env

Question

我每2秒更新一次我的API，
但我收到此错误，并且我的应用程序关闭。

FATAL EXCEPTION: main Process: com.application.toweeloasep, PID: 6681 java.lang.OutOfMemoryError: Could not allocate JNI Env at java.lang.Thread.nativeCreate(Native Method) at java.lang.Thread.start(Thread.java:730) at com.android.volley.RequestQueue.start(RequestQueue.java:145) at com.android.volley.toolbox.Volley.newRequestQueue(Volley.java:66) at com.android.volley.toolbox.Volley.newRequestQueue(Volley.java:78) at com.application.toweeloasep.fragments.Jobs$5$1.run(Jobs.java:260) at android.os.Handler.handleCallback(Handler.java:751) at android.os.Handler.dispatchMessage(Handler.java:95) at android.os.Looper.loop(Looper.java:154) at android.app.ActivityThread.main(ActivityThread.java:6077) at java.lang.reflect.Method.invoke(Native Method) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:865) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:755)

大约一分钟后，它开始崩溃并收到该错误。
我是否用Volley做得太过分了？

OutOfMemoryError ... at com.android.volley.toolbox.Volley.newRequestQueue

为什么你需要创建一个新的请求队列或StringRequest每两秒钟？

试着只做一个。

private final Response.ErrorListener errorListener = new Response.ErrorListener() { 
    @Override 
    public void onErrorResponse(VolleyError error) { 
     Log.e("ERR", String.valueOf(error)); 
    } 
}; 

private void setRepeatingVolleyTask() { 
    final RequestQueue mRequestQueue = Volley.newRequestQueue(getActivity()); 

    final StringRequest trackRequest = new StringRequest(Request.Method.POST, "http://api.toweelo.com/booking/track", new Response.Listener<String>() { 
     @Override 
     public void onResponse(String response) { 
      Log.d("RESPONSE:TRACK", response); 
      try { 
       JSONObject json = new JSONObject(response); 
       String mStatus = json.getString("status"); 
       if (mStatus.equalsIgnoreCase("0")) { 
        Log.d("STATUS", mStatus); 
       } else if (mStatus.equalsIgnoreCase("1")) { 
        JSONArray infos = json.getJSONArray("data"); 
        booking_id = infos.getJSONObject(0).getString("id"); 
        user_address_location = infos.getJSONObject(0).getString("user_address_location"); 
        mTxtBatteryInfo.setText(infos.getJSONObject(0).getJSONObject("battery").getString("model")); 
        mTxtUserLocation.setText(user_address_location); 
        checkRequests = false; 
        mJobsHome.setVisibility(View.GONE); 
        mJobRequest.setVisibility(View.VISIBLE); 
        if (!onTick) { 
         mCountDownTimer.start(); 
         onTick = true; 
        } 
       } 
      } catch (Exception e) { 
       Log.e("ERR", e.toString()); 
      } 
     } 
    }, errorListener); 

    final StringRequest trackRequest2 = new StringRequest(Request.Method.POST, "http://api.toweelo.com/booking/track", new Response.Listener<String>() { 
     @Override 
     public void onResponse(String response) { 
      Log.d("RESPONSE", response); 
     } 
    }, errorListener) { 
     @Override 
     protected Map<String, String> getParams() throws AuthFailureError { 
      Map<String, String> params = new HashMap<>(); 
      params.put("booking_id", booking_id); 
      params.put("rider_long", String.valueOf(lng)); 
      params.put("rider_lat", String.valueOf(lat)); 
      return params; 
     } 
    }; 

    Timer timer = new Timer(); 
    TimerTask task = new TimerTask() { 
     @Override 
     public void run() { 
      handler.post(new Runnable() { 
       public void run() { 
        // What are you trying to catch here?? 
        try { 
         if (checkRequests) { 
          mRequestQueue.add(trackRequest); 
         } else { 
          mRequestQueue.add(trackRequest2); 
        } catch (...) { 
         .... 
        } 

注意：您可以使用JsonObjectRequest而不是从StringRequest
