我已經(jīng)加入uses-permission包括WRITE_EXTERNAL_STORAGE，MOUNT_UNMOUNT_FILESYSTEMS，READ_EXTERNAL_STORAGE來AndroidManifest.xml。當(dāng)我嘗試在Nexus5（Android 6.0）中運(yùn)行我的應(yīng)用程序時(shí)，它引發(fā)了如下異常：java.io.IOException: open failed: EACCES (Permission denied)然后我嘗試了另一部Android手機(jī)（Android 5.1），一切正常。代碼如下：private File createImageFile() throws IOException {    String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());    String imageFileName = "JPEG_" + timeStamp + "_";    File storageDir = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES);    File image = File.createTempFile(imageFileName, ".jpg", storageDir);    currentPhotoPath = image.getAbsolutePath();    return image;}Android 6.0在權(quán)限方面有區(qū)別嗎？
