Android的图像不会保存在使用Nexus S的原生相机应用 [英] Android Image doesn't save using native camera app on Nexus S

问题描述

因此​​，这是一种奇怪的，因为出了三个设备我测试上，我只得到这个问题的谷歌Nexus S采用4.0.3。我开始原生相机应用拍照，我不在乎保存图像，所以我不指定，希望它会被保存到默认位置，但没有位置被保存在所有！

是否在Galaxy S 2和三星扶摇直上做工精细（都与2.3.something）。

code我使用来启动应用程序

 意图camIntent =新意图（MediaStore.ACTION_IM​​AGE_CAPTURE）;
startActivityForResult（camIntent，TAKE_PHOTO）;
返回true;
 

我保持它很简单，这就是为什么我很困惑！有谁知道具体到歌Nexus S的摄像头的问题？

编辑：这似乎是可能的歌Nexus S的摄像头应用程序可以节省一些的onActivityResult的文件，因为我启动本机摄像头的应用程序，不保存在返回的形象，这不是T保存。有谁知道这这是真的吗？看到这种行为？

编辑：没有人见过这个？我很难相信我碰到这个第一人......

编辑：好吧，它的工作多一些好后，我尝试添加一个URI到意图EXTRA_OUTPUT像这样：

  camIntent.putExtra（MediaStore.EXTRA_OUTPUT，
                            Uri.parse（FOLDERPATH +的String.format（％D.JPG，返回System.currentTimeMillis（））））;
 

而现在我看到这里所描述的行为：的Andr​​oid ACTION_IM​​AGE_CAPTURE意图相机进行应用程序没有做任何事情，当我点击确定，并创建文件事先也不管用，因为我想是这样的：

 文件f =新的文件（FOLDERPATH，文件名）;
f.createNewFile（）;
camIntent.putExtra（MediaStore.EXTRA_OUTPUT，Uri.parse（FOLDERPATH +文件名））;
 

解决方案

好吧，理解了它。奇怪的是，我不知道为什么，但改变这一行：

  camIntent.putExtra（MediaStore.EXTRA_OUTPUT，Uri.parse（FOLDERPATH +文件名））;
 

到

  camIntent.putExtra（MediaStore.EXTRA_OUTPUT，Uri.fromFile（文件））;
 

固定它。不知道是不是我应该明白为什么......但不管，它的工作原理。我也尝试了十亿其他的事情...

不指定EXTRA_OUTPUT在所有 - >相机会像一切都很好...除了它不会保存图像ANYWHERE

过得去intent.getExtras（）采取的位图获取（数据） - >回做一个位图，但它并不像很多错误报告广泛记录了全尺寸图片

使用上述方法Uri.parse

- >使原生相机应用的勾号按钮点击时没有做任何事情。

希望这可以帮助别人。

So this is kind of weird because out of the three devices I'm testing on, I only get this issue on the Google Nexus S with 4.0.3. I'm starting the native camera app to take a picture, and I don't care where the image is saved to, so I don't specify, hoping that it will get saved to the default location, but no location is saved at all!

Does work fine on the Galaxy S 2 and Samsung Skyrocket (both with 2.3.something).

Code I'm using to start the app

Intent camIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(camIntent, TAKE_PHOTO);
return true;

I'm keeping it really simple, that's why I'm confused! Does anyone know of any issues specific to the Nexus S's camera?

EDIT: It would seem that maybe the Nexus S's camera app saves the file in some onActivityResult, and since I start up the native camera app and don't save the image upon return, it doesn't save it. Does anyone know this this to be true? Seen this behavior?

EDIT: No one has seen this? I find it hard to believe I'm the first person to run into this...

EDIT: Alright, well after working on it some more, I tried adding a URI into the EXTRA_OUTPUT of the intent like so:

camIntent.putExtra(MediaStore.EXTRA_OUTPUT,
                            Uri.parse(folderPath + String.format("%d.jpg", System.currentTimeMillis())));

And now I see the behavior described here: Android ACTION_IMAGE_CAPTURE Intent where the camera app doesn't do anything when I hit ok, and creating the file beforehand doesn't work either, as I tried like this:

File f = new File(folderPath, filename);
f.createNewFile();
camIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.parse(folderPath + filename));

解决方案

Alright, figured it out. Oddly, and I have NO idea why, but changing this line:

camIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.parse(folderPath + filename));

to

camIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(file));

fixed it. Don't know if I should understand why... but whatever, it works. I did try a billion other things...

not specifying an EXTRA_OUTPUT at all -> camera would act like everything was good... except it wouldn't save the image ANYWHERE

getting the bitmap taken by intent.getExtras().get("data") -> did return a bitmap, but it was not the full size image as documented extensively in many bug reports

using the above Uri.parse method -> causes the native camera app checkmark button to not do anything when clicked

Hope this helps someone..
