Android：启动抽屉布局时出现内存不足错误

Question

我在调试代码时遇到内存不足错误，它在以下代码行中失败：

 setContentView(R.layout.activity_drawer);

错误如下：

我的 activity_drawer XML 代码如下所示：

<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
    android:layout_height="match_parent" android:id="@+id/drawer_layout"
    tools:context=".ActivityDrawer">
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical">
        <android.support.v7.widget.Toolbar
            android:id="@+id/tool_bar"
            theme="@style/MyToolbarThemeSimple.Base"
            android:layout_height="wrap_content"
            android:layout_width="match_parent"
            android:minHeight="?attr/actionBarSize"
            android:background="@color/colorPrimary"
            >
        </android.support.v7.widget.Toolbar>
        <FrameLayout
            android:id="@+id/container"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            >

        </FrameLayout>
    </LinearLayout>
    <!--  The Navigation drawer      -->
    <RelativeLayout
        android:layout_width="240dp"
        android:layout_height="match_parent"
        android:background="@color/windowBackground"
        android:id="@+id/drawer"
        android:layout_gravity="start">

        <android.support.v7.widget.RecyclerView
            android:layout_width="match_parent"
            android:layout_height="fill_parent"
            android:id="@+id/cardview_drawer"
            />

    </RelativeLayout>
</android.support.v4.widget.DrawerLayout>

我已经尝试了很多事情，比如我通过使用编译器 VM 选项将堆大小增加到 -Xmx2048m -XX:MaxPermSize=512m。
另外，我检查了设置中存在的选项 "compile independent modules in parallel" => 构建、执行、开发环境 => 编译器但是没有任何结果..有帮助吗？？

如果您的图像太大而无法加载（导致OutOfMemoryError。

，通常会出现此类错误

我建议缩小您的图像，或使用较低分辨率的图像，以便更容易将其加载到内存中。

您还可以访问各种资源，包括 Android developer docs with a sample app, as well as YouTube videos such as this one。
