我登錄了uri.getpath，它返回file:///mnt/sdcard/1358731920220.jpg。此鏈接似乎有額外的/。但是，我不確定爲什麼會這樣？java.io.FileNotFoundException：/mnt/sdcard/1358731920220.jpg（沒有這樣的文件或目錄）

它是一個文件：// uri。路徑是/ mnt/sdcard ...當你把它們放在一起時，你會得到file：/// mnt/sdcard –

@GregS如何解決它？ –

請根據標題詢問更具體的問題。 – herbertD

添加此權限清單文件，如果你還沒有加入，

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

已經添加了，如果不是不會得到路徑 –

看看[這個鏈接]（http://stackoverflow.com/questions/8845534/getting-file-not-found-exception）。 – abhi

cropIntent.putExtra("return-data", true);

變化

cropIntent.putExtra("return-data", false);

將裁剪後的圖片保存到SD卡。
