imageio.IIOException：无法读取输入文件（无法读取或写入核外文件）

我一周前开始使用Java，现在我想在窗口中插入一个图像。无论我尝试什么，我都会在Eclipse中继续使用它：
javax.imageio.IIOException：无法读取输入文件！

package graphics;import java.awt.Color;import java.awt.Graphics;import java.awt.Image;import java.io.File;import java.io.IOException;import javax.imageio.ImageIO;import javax.swing.JFrame;import javax.swing.JPanel;import src.Common;public class Window extends JFrame{public class Panel extends JPanel{    public void paintComponent(Graphics g)    {        Image img;         try         {        img = ImageIO.read(new File("/logo.jpg"));        g.drawImage(img, 0, 0, this);        }         catch (IOException e)         {        e.printStackTrace();        }    }}public Window(String title, int width, int height){    this.setTitle(title);    this.setSize(width, height);    this.setLocationRelativeTo(null);    this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);    this.setContentPane(new Panel());     this.setVisible(true);}

}

我认为代码很容易解释。我试图解决这个问题

我想做的是一个桌面程序，我的源代码存储如下：training / src / graphics / Window training / src / src
/ main

我确实将要读取的图像放在每个文件夹中，仍然出现问题：/

我做错什么了？

编辑终于解决了，这里的答案

nICECOWW给了我帮助的链接。因此，我确实将图像放入文件夹中，并按照链接中所述更改了访问图像的方式。

getClass().getResource("/images/yourImageName.extension");

答案1

小编典典

您是否尝试过使用new File("logo.jpg");（没有前导/）？

并且确定将logo.jpg复制到输出中吗？（某些IDE不会将每个文件从源目录复制到输出（或目标）目录。）

/src|-> Window.java|-> Logo.jpg

变成

/out|-> Window.class

（请注意，IDE /编译器不会将映像复制到输出目录中，因此尽管您指定了正确的路径，但是编译后的代码无法找到该映像）

Android FATAL EXCEPTION MAIN：java.lang.RuntimeException：无法启动活动ComponentInfo

我是编程android的nubie,我知道这里有4m是很多页面为我的问题打乱解决方案,但现在我输了2天仍然没有得到解决方案.请帮我！

解决方法:

您的活动名称是WifiScan但您已将其声明为.activity_wifi_scan更改它并重试.

更改<活动>要素：

<activity android:name=".WifiScan">
         <intent-filter>
                 <action android:name="android.intent.action.MAIN"></action>
                 <category android:name="android.intent.category.LAUNCHER"></category>
                 <data />
         </intent-filter>
     </activity>

Android Studio – java.io.IOException：无法生成v1签名

我将Android Studio更新到3.0 Canary 4之后的所有新版本后出现此错误.(我使用的是v3.0,因为它更快,并且不需要为Kotlin插孔.)

看起来构建流程存在问题,它无法为调试版本和发布版本生成或签署我的APK文件.

我也尝试删除我的debug.keystore,重新启动AndroidStudio和系统(!!!),但它没有解决.

这是一个完整的Gradle日志：

BUILD Failed in 2m 49s

解决方法:

在使用gradle assemble –stacktrace命令进行更多调查后,我发现问题与APK压缩过程有关：

Error:org.gradle.tooling.BuildException: Failed to generate v1
signature Error:java.io.IOException: Failed to generate v1 signature
Error:com.android.apksig.apk.ApkFormatException: Unsupported character
0x0d in ZIP entry name “assets/Icon?”

有一个名为“Icon？”的文件.在我的项目中,这是一个MacOS文件,指示文件夹的图标,里面包含CR,LF字符.

我删除了文件,现在一切正常.

此问题出现在Android Studio Canary 4之后的所有版本中,我在此线程https://issuetracker.google.com/issues/63885809上向Android Studio团队报告此问题

他们提到：

3.0 Canary 4 is about the time we added that “Unsupported character” check, so that’s why it happens from that version forward.

他们正在调查更多以解决这个问题,我希望这个答案可以帮助其他人不浪费一个月不更新他们的Android Studio.

android – 解压缩zip文件给出“java.util.zip.ZipException：无法读取版本”或“java.util.ZipException无法读取本地标题版本45”

我想提取一个普通的zip文件,但它仍然失败.
这是我现在使用的代码：

private File downloadpath = new File(Environment.getExternalStorageDirectory() + "/Test/file.zip");
private File unzipLoc = new File(Environment.getExternalStorageDirectory() + "/Test/");
        FileInputStream fin = new FileInputStream(downloadpath); 
        ZipInputStream zin = new ZipInputStream(fin);
        ZipEntry ze = null; 
        while ((ze = zin.getNextEntry()) != null) 
        { 
            FileOutputStream fout = new FileOutputStream(unzipLoc + ze.getName()); 
            for (int c = zin.read(); c != -1; c = zin.read()) 
            { 
                fout.write(c); 
            } 

            zin.closeEntry(); 
            fout.close(); 
        } 
        zin.close();

它在’zin.getNextEntry()’部分失败.
错误：java.util.zip.ZipException：无法读取版本
有任何想法吗？谢谢！

解决方法:

看起来你的zip文件比你的’解压缩库’更新.

如果您阅读来源：

ZipInputStream(搜索新的ZipException(“无法读取版本”))

它显示它检查zip文件版本.然后查看Wikipedia它显示这是提取zip所需的最低版本.

检查您的zip文件并使用较低版本的zip软件重新保存/再次压缩,无需压缩即可测试

或者更新你的Zip库(你不能使用内部的android zip库).

android – 错误：任务’：app：packageRelease’的执行失败. > java.io.IOException：无法读取zip文件

当我尝试构建发布版本时,我收到以下错误.我正在使用 android studio 2.3.我已经在下面添加了我的gradle和proguard规则文件,我使用mac与mac os X.

Error:Execution Failed for task ':app:packageRelease'.

解决方法

此问题在项目中引用 here,包括非ASCII类名称.该问题将从Gradle Android插件版本2.4(目前尚未发布)中解决.

另一种方法是降级到2.2.3：

classpath 'com.android.tools.build:gradle:2.2.3'
