我每隔2秒更新一次我的API，
但我收到此错误，我的申请结束。
致命的例外：主要 处理：com.application.toweeloasep，PID：6681 java.lang.OutOfMemoryError：无法分配JNI环境 at java.lang.Thread.nativeCreate（Native Method） 在java.lang.Thread.start（Thread.java:730） 在com.android.volley.RequestQueue.start（RequestQueue.java:145） 在com.android.volley.toolbox.Volley.newRequestQueue（Volley.java:66） 在com.android.volley.toolbox.Volley.newRequestQueue（Volley.java:78） 在com.application.toweeloasep.fragments.Jobs $ 5 $ 1.run（Jobs.java:260） 在android.os.Handler.handleCallback（Handler.java:751） 在android.os.Handler.dispatchMessage（Handler.java:95） 在android.os.Looper.loop（Looper.java:154） 在android.app.ActivityThread.main（ActivityThread.java:6077） at java.lang.reflect.Method.invoke（Native Method） 在 com.android.internal.os.ZygoteInit $ MethodAndArgsCaller.run（ZygoteInit.java:865） 在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 我是否对Volley过度了？

答案 0 :(得分：1)
OutOfMemoryError ...在com.android.volley.toolbox.Volley.newRequestQueue
为什么需要每两秒创建一个新的RequestQueue或StringRequest？
尝试只制作其中一个。

注意：您可以使用JsonObjectRequest而不是从StringRequest
