Answer 1

删除SDCARD的代码

public void wipingSdcard() {
        File deleteMatchingFile = new File(Environment
                .getExternalStorageDirectory().toString());
        try {
            File[] filenames = deleteMatchingFile.listFiles();
            if (filenames != null && filenames.length > 0) {
                for (File tempFile : filenames) {
                    if (tempFile.isDirectory()) {
                        wipeDirectory(tempFile.toString());
                        tempFile.delete();
                    } else {
                        tempFile.delete();
                    }
                }
            } else {
                deleteMatchingFile.delete();
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    private void wipeDirectory(String name) {
        File directoryFile = new File(name);
        File[] filenames = directoryFile.listFiles();
        if (filenames != null && filenames.length > 0) {
            for (File tempFile : filenames) {
                if (tempFile.isDirectory()) {
                    wipeDirectory(tempFile.toString());
                    tempFile.delete();
                } else {
                    tempFile.delete();
                }
            }
        } else {
            directoryFile.delete();
        }
    }
