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。
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。
撸主你这个问题我之前也遇到过,纠结了一天才解决。
![](http://img.php.cn/upload/image/000/000/000/3a278f4aee135b8213fac4454a8db7ac-0.jpg)
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。
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
