Java を使用して zip ファイルを作成していますが、コードを動作させることができません。Java 7 および Java 8 に固有の方法をさらに多く試しましたが、それらのすべてに何らかのエラーが表示されます。コードに間違いがあるのでしょうか、それとも改善が必要ですか?
File destination = null;
JFileChooser chooser1 = new JFileChooser();
chooser1.setDialogTitle("Select a directory with APK file contents");
chooser1.setCurrentDirectory(new java.io.File("."));
chooser1.setAcceptAllFileFilterUsed(false);
chooser1.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);
int returnVal = chooser1.showOpenDialog(getParent());
if (returnVal == JFileChooser.APPROVE_OPTION) {
destination = chooser1.getSelectedFile();
JFileChooser chooser2 = new JFileChooser();
FileNameExtensionFilter filter = new FileNameExtensionFilter("APK Files", "apk");
chooser2.setFileFilter(filter);
chooser2.setDialogTitle("Save APK as");
int userSelection = chooser2.showSaveDialog(parentFrame);
if (userSelection == JFileChooser.APPROVE_OPTION) {
File apksavedestination = chooser2.getSelectedFile();
String apkname = chooser2.getSelectedFile().getName() + ".apk";
String zipFile = apksavedestination + apkname;
String zipfileSource = destination.getAbsolutePath();
try {
ZipFile zipFileAtLast = new ZipFile(zipFile);
ArrayList<File> inFolder = new ArrayList<File>();
inFolder.add(new File(destination.getAbsolutePath()));
ZipParameters parameters = new ZipParameters();
parameters.setIncludeRootFolder(false);
parameters.setCompressionMethod(Zip4jConstants.COMP_DEFLATE);
parameters.setCompressionLevel(Zip4jConstants.DEFLATE_LEVEL_NORMAL);
zipFileAtLast.addFolder(inFolder, parameters);
} catch (ZipException e1) {
e1.printStackTrace();
}
この行でエラーが発生しますzipFileAtLast.addFolder(inFolder, parameters);
私を案内してください:)
実行時のエラー:
