Question

当我调试我的代码时，我面临内存不足错误，它在下面的代码行中失败：

 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>

我尝试过很多东西，例如我使用编译器VM选项将堆大小增加到-Xmx2048m -XX：MaxPermSize = 512m。
另外，我检查了选项＆＃34;并行编译独立模块＆＃34;在Settings =＆gt;内显示构建，执行，发展环境=＆gt;编译器但没有成功..任何帮助？

Answer 1

如果您的图片太大而无法加载（导致OutOfMemoryError，则通常会发生此类错误。

我建议缩小你的图像，或使用较低分辨率的图像，这样它就可以更容易地加载到内存中。

您还可以访问各种来源，包括带有示例应用的Android developer docs以及this one等YouTube视频。
