完全释放此活动持续的所有内存后，从此活动开始活动

我从活动A开始活动B.并且希望活动A被完全销毁并释放所有持有的内存以释放活动B开始就好像它首先开始。我有一个onClick方法按钮，它完成了这个活动，并使用从here复制的方法unbindDrawables。完全释放此活动持续的所有内存后，从此活动开始活动

//inside activity A 

public void onClickMethod(View v){ 
     Intent intent = new Intent(this, EarthRoomActivity.class); 
     intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); 
     startActivity(intent);// starting activity B 
     unbindDrawables(findViewById(R.id.water_room_flipper)); 
     this.finish(); 
} 

static void unbindDrawables(View view) { 
try{ 
System.out.println("UNBINDING"+view); 
    if (view.getBackground() != null) { 
     ((BitmapDrawable)view.getBackground()).getBitmap().recycle(); 
     view.getBackground().setCallback(null); 
     view=null; 
    } 
    if (view instanceof ViewGroup) { 
     for (int i = 0; i < ((ViewGroup) view).getChildCount(); i++) { 
     unbindDrawables(((ViewGroup) view).getChildAt(i)); 
     } 
    ((ViewGroup) view).removeAllViews(); 
    } 
}catch (Exception e) { 
// TODO: handle exception 
e.printStackTrace(); 
}}

但nevertheles我得到这个错误：

我不得不提的是，当我开始从Android清单活动B成为首个应用程序被启动，它将启动没有错误。

活动B的xml：

<?xml version="1.0" encoding="utf-8"?> 
<FrameLayout android:layout_width="fill_parent" android:id="@+id/earth_room_layout" 
    android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android"> 

    <ViewFlipper android:id="@+id/water_room_flipper" 
     android:layout_width="fill_parent" android:layout_height="fill_parent"> 
     <include layout="@layout/earth_room_wall1" android:id="@+id/first" /> 
     <include layout="@layout/earth_room_wall2" android:id="@+id/second" /> 
     <include layout="@layout/earth_room_wall3" android:id="@+id/third" /> 
     <include layout="@layout/earth_room_wall4" android:id="@+id/fourth" /> 
    </ViewFlipper> 

    <com.example.room.CustomView android:id="@+id/customView" 
     android:layout_width="fill_parent" android:layout_height="fill_parent" /> 
</FrameLayout>

如果我从它的工作ViewFlipper删除最后。即它必须做OutOfMemory错误。但是，我确实发布了A持有的所有活动，对吗？或者我可能错过了smth？

'android.view.InflateException：二进制XML文件行＃1：错误'看起来问题在于您的'XML'，您没有发布。 – nhgrif

我已将它添加到编辑中。请看一看。 – Nazerke

就像一个评论，[FrameLayouts]（http://developer.android.com/reference/android/widget/FrameLayout.html）不应该正常地用于存储多个子视图。 –

似乎是坏了活动B的布局，似乎错误是线＃1，也许你忘了在顶部加入

<?xml version="1.0" encoding="utf-8"?>

。如果您发布布局，我可以进一步帮助您。
