我正在尝试显示通过存储的相机意图(触发内置相机应用程序)捕获的图片external SD-card.

文件路径和文件名存储在String变量中'mCurrentPhotoPath'.

我已经验证捕获的图像存储在'mCurrentPhotoPath'使用ES File Explorerapp 指定的位置,但BitmapFactory.decodeFile(mCurrentPhotoPath, bmOptions)始终返回FileNotFoundException.这是我存储捕获图像的代码:

    private void addPicToGallery() {

    File f = new File(mCurrentPhotoPath);
    //for debug purpose only
    Log.i(MYTAG, "value of mCurrentPhotoPath in addPicToGallery: " +mCurrentPhotoPath);
    Log.i(MYTAG, "value of f in addPicToGallery:  " +f);

    Uri contentUri = Uri.fromFile(f);

    //for debug only
    Log.i(MYTAG, "value of contentUri in addPicToGallery: " +contentUri);

    Intent mediaScanIntent = new    Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
    mediaScanIntent.setData(contentUri);
    sendBroadcast(mediaScanIntent);

}

解码缩放图像的代码,用于显示ImageView:

    private void setFullImageFromFilePath() {

    Log.i(MYTAG, …
