安卓：附加圖像以電子郵件的意圖 - 錯誤

我試圖附加圖像文件發送意圖（如Gmail等）這裏是我的代碼：安卓：附加圖像以電子郵件的意圖 - 錯誤

public void mail(ReadableMap options, Callback callback) { 
Intent i = new Intent(Intent.ACTION_SEND); 
    i.setType("application/image"); 

    if (options.hasKey("subject") && !options.isNull("subject")) { 
    i.putExtra(Intent.EXTRA_SUBJECT, options.getString("subject")); 
} 

if (options.hasKey("body") && !options.isNull("body")) { 
    i.putExtra(Intent.EXTRA_TEXT, options.getString("body")); 
} 

if (options.hasKey("recipients") && !options.isNull("recipients")) { 
    ReadableArray r = options.getArray("recipients"); 
    int length = r.size(); 
    String[] recipients = new String[length]; 
    for (int keyIndex = 0; keyIndex < length; keyIndex++) { 
    recipients[keyIndex] = r.getString(keyIndex); 
    } 
    i.putExtra(Intent.EXTRA_EMAIL, recipients); 
} 

if (options.hasKey("attachment") && !options.isNull("attachment")) { 
    ReadableArray r = options.getArray("attachment"); 
    Uri uri = Uri.fromFile(new File(Environment.getExternalStorageDirectory(), r.getString(0))); 
//  Log.e("FILE", r.getString(0)); 
    i.putExtra(Intent.EXTRA_STREAM, uri); 
} 

Intent chooser = Intent.createChooser(i, "Send Mail"); 

chooser.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); 
try { 
    reactContext.startActivity(chooser); 
} catch (Exception ex) { 
    callback.invoke("error"); 
} 
}

圖像在設備上有效，但返回錯誤：無法附加空文件。其他電子郵件字段在GMail應用程序中運行良好。

下面是Android Studio中的輸出：

當你說'記錄返回：'時，你說什麼日誌？ Log.e（）？ – greenapps

是的，這就是我的意思...... –

Uri uri = Uri.fromFile(new File(Environment.getExternalStorageDirectory(), r.getString(0)));

更改爲：

Uri uri = Uri.parse(r.getString(0));

R.getSting已經包含完整路徑所以沒必要弄添加外部存儲。
