关于启动新活动的OutOfMemoryError

Question

我正尝试通过以下方式从其他活动启动活动：

Intent loginActivity = new Intent(mainAppContext,LoginActivity.class);
loginActivity.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
loginActivity.putExtra("Message", mainAppContext.getResources().getString(R.string.RegisteringUserAPIFailure));
mainAppContext.startActivity(loginActivity);

新活动布局只有两张图片，其中一张ImageView为7kb，另一张ImageButton为11kb。哪个不应该生成OutOfMemoryError？

但这会产生以下错误：

Answer 1

看起来你正在使用矢量绘图。

确保它们具有合理的固有尺寸（宽度和高度）

e.g：

<vector xmlns:android="http://schemas.android.com/apk/res/android" 
    android:viewportWidth="512" android:viewportHeight="512"
    android:width="64dp" android:height="64dp">

如果您将尺寸设置得太大，当系统尝试显示它们时，它们将抛出内存不足错误，因为它将首先尝试以您设置的尺寸创建它们。

Answer 2

可能图像非常大，试着让它们变小。或者阅读this article http://developer.android.com/intl/es/training/displaying-bitmaps/load-bitmap.html

Answer 3

只需添加更高的HeapSize，大多数应用都无法使用默认堆，在app / buid.gradle中添加：

android { 
    ...
    dexOptions {
        javaMaxHeapSize "8g"
        incremental true
    }
    ...
}
