安卓：恒内存消耗/ dumpGfxInfo（） [英] Android: Constant memory consumption / dumpGfxInfo()

问题描述

假设：使用Android工作室向导，创建一个简单的活动，而不在任何自定义code，永远消耗内存调用dumpGfxInfo（）

Given: A simple Activity created with the Android Studio Wizard, without any custom code inside, consumes perpetually memory calling dumpGfxInfo().

而Android Studio的建立在分配追踪器至少揭示了的三的做同样的主题：

The Android Studio's build in Allocation Tracker reveals at least three threads doing the same:

 --- 8< ------------------------------------------------------------------

 * < Thread 12 > 
   * execTransact():446, Binder (andoroid.os)   
     * onTransact():545, ApplicationThreadNative (android.app)
       * dumpGfxInfo():1107, ActivityThread$ApplicationThread (android.app)

 --- 8< -------------------------------------------------------------------

显然dumpGfxInfo（）通过为空字符串分配内存消耗内存。编译唯一相关的依赖，是的 com.android.support:appcompat-v7:22.2.1 的

随着这种内存消耗，以下异常（有时）出现了：

Along with this memory consumption, following exception (sometimes) arises:

15331-15364/ W/Binder﹕ Caught a RuntimeException from the binder stub implementation.
    java.lang.NullPointerException: Attempt to read from field 'android.view.HardwareRenderer android.view.View$AttachInfo.mHardwareRenderer' on a null object reference
            at android.view.WindowManagerGlobal.dumpGfxInfo(WindowManagerGlobal.java:466)
            at android.app.ActivityThread$ApplicationThread.dumpGfxInfo(ActivityThread.java:1107)
            at android.app.ApplicationThreadNative.onTransact(ApplicationThreadNative.java:548)
            at android.os.Binder.execTransact(Binder.java:446)

问：如何修复/关闭此行为，并摆脱它

Question: How to fix/turn off this behaviour and get rid of it?

推荐答案

好像它是最新的Andr​​oid工作室的bug。 较早的版本没有这个问题。 请参阅<一href="https://$c$c.google.com/p/android/issues/detail?can=2&start=0&num=100&q=&colspec=ID%20Type%20Status%20Owner%20Summary%20Stars&groupby=&sort=&id=182869&">this链接

Seems like it's latest Android Studio bug. Older versions don't have this issue. See this link
