【安卓】Android Studio 2.0 最简单的纯图片程序闪退 为什么？

升级Android Studio 新建项目，默认Hello World 运行没有问题，删掉TextView，换成ImageView，只加载一个图，编译运行，程序闪退，下变为源码。

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 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:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context="com.example.android.happybirthday.MainActivity">
<ImageView
android:src="https://segmentfault.com/q/1010000004913671/@drawable/androidplay"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</RelativeLayout>

图片为1.19MB，2880*1800分辨率，放在drawable目录下，图片没有问题，在另一个同学的那里相同代码可以编译并顺利运行，相同代码和图片放在eclipse没有问题。
闪退后错误信息

换一张小图，1254*1254分辨率的就能够顺利运行，仅仅换了张图，将那张大图放在mipmap目录下，使用@mipmap就能运行。

想着是编译器出问题了，重装了整个AS，但还是不行，并且有时候错误信息是内存泄漏或者OOM

请各路大神帮忙！感激不尽。

回答

撸主你这个问题我之前也遇到过，纠结了一天才解决。
如楼上所说，2880*1800的argb会占20m内存。但就算一张图20m内存，也不应该每次都出现oom，因为现在的机器几乎没有16m默认堆的情况了，比如我现在这个mxpro，前年的机器，默认256，largeheap是512。
如果情况特殊，可以在manifest文件中申请largeheap，但这不是本问题的所在。
问题出在drawable文件夹上，这个文件夹是对dpi敏感的。
如果你屏幕分辨率是1920*1080，那么，屏幕dpi是480，drawable文件夹下的图片，据我推测会当做120dpi的处理，也就是说，会将图片放大四倍，1w+的尺寸，爆内存是肯定的了。

上图是一个project的res文件夹，对于drawable也可以有相应的dpi级别，你这张图，最好的选择是放在xxxhdpi下，这样如果在低dpi机器上时会自动缩放，还是你这个1920*1080,480dpi的机器上，实际图片大小会缩放为480/640，也就是四分之三，很大程度上优化了内存使用。
最不济，你得放在nodpi文件夹下，这样起码它不会自动放大。
最后上个Google官方的dpi对应数据
A set of six generalized densities:
ldpi (low) ~120dpi
mdpi (medium) ~160dpi
hdpi (high) ~240dpi
xhdpi (extra-high) ~320dpi
xxhdpi (extra-extra-high) ~480dpi
xxxhdpi (extra-extra-extra-high) ~640dpi

http://developer.android.com/intl/zh-cn/...
Google对于这方面的官方指导，顺便补充下，我上面对于默认dpi的猜测是错误的，默认是160dpi。

我想你应该恶补一下图片在内存中存储的方式，简单的说吧，不是编译的问题，是内存爆了所以崩溃了。
给你计算你一下你这张图片所占用的内存：
2880 * 1800 = 5148000 (px)
5148000 * 4Byte = 20736000 (Byte) = 19.78 (MB)
一张图片占用近20MB的内存空间，而Android标配给一个App的内存空间只有16MB，能不爆吗？

我看错了 不是2.0问题

你看看你的activity里有没有下面这个函数，有的话删了。

@Override public void onSaveInstanceState(Bundle outState, PersistableBundle outPersistentState) { 
    super.onSaveInstanceState(outState, outPersistentState); 
}

不是吧，就是内存溢出了吧。之所以其他可以和手机有关吧，低内存自然就爆了，和AS无关，我这边也今天升级的，跑原来的应用没有问题

楼上正解，图片大小要控制啊。一个像素可是4个字节的哦

不是 AS 的问题，是图片太大，内存溢出的问题，就行楼上几位所说的。

关于显示大图片，可以参考官方的文档：Loading Large Bitmaps Efficiently
