我是靠谱客的博主土豪煎饼，最近开发中收集的这篇文章主要介绍解决“java.lang.OutOfMemoryError: Failed to allocate a allocation until OOM”错误，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

1.参考:解决“java.lang.OutOfMemoryError: Failed to allocate a allocation until OOM”错误_SEVENY_的博客-CSDN博客

“java.lang.OutOfMemoryError: Failed to allocate a allocation until OOM”内存溢出错误是在Android app运行的时候出现的，这可能是因为app RAM中缓存太多文件或反复实例化相同的位图和视频造成的内存不足现象，下面是我在运行时候所出现的错误。

java.lang.OutOfMemoryError: Failed to allocate a 29859852 byte allocation with 3827656 free bytes and 3MB until OOM

可以在androidmenifest.xml文件中更改application配置，将hardwareAccelerated设置为false，largeHeap设置为true。

android:largeHeap = "true"
android:hardwareAccelerated = "false"
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:roundIcon="@mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="@style/AppTheme">

android:hardwareAccelerated = "true"的时候会牺牲内存来加快图片的加载速度。

android:largeHeap = "false"会限制app应用申请的内存大小。
