遇到 java.io.IOException: open failed: ENOENT (No such file or directory)

Question

我目前正在關注此https://developer.android.com/training/camera/photobasics.html教程，使用此方法時出現該錯誤

private File createImageFile() throws IOException {
    // Create an image file name
    String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
    String imageFileName = "JPEG_" + timeStamp + "_";
    File storageDir = getExternalFilesDir(Environment.DIRECTORY_PICTURES);
    File image = File.createTempFile(
        imageFileName,  /* prefix */
        ".jpg",         /* suffix */
        storageDir      /* directory */
    );

    // Save a file: path for use with ACTION_VIEW intents
    mCurrentPhotoPath = image.getAbsolutePath();
    return image;
}

我在網上嘗試過其他解決方案，但沒有一個對我有用。 我還添加了適當的權限

Answer 1

您是否嘗試添加此權限？

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
