無法在清單

Question

當使用「使用-SDK」我創建一個應用程序來記錄語音保存文件的SD卡，當我試圖存儲在SD卡文件，

<uses-sdk android:minSdkVersion="8" 

它給我的錯誤「不這樣的文件或目錄「，但是當我從清單註釋掉」uses-sdk「部分時，它工作正常。我不確定實際的問題是什麼，但似乎是由於在清單中設置sdk-version。 我也嘗試增加/減少minSdkVersion，但仍然是相同的錯誤。

下面是錯誤日誌。

我的代碼來創建文件

private String getFilename(){ 
     String filepath = Environment.getExternalStorageDirectory().getPath(); 
     File file = new File(filepath,AUDIO_RECORDER_FOLDER); 

     if(!file.exists()){ 
      file.mkdirs(); 
     } 

     return (file.getAbsolutePath() + "/" + AUDIO_FILE_NAME + ".3gp"); 
    } 

Answer 1

您在清單正在做的事情做的正確的方法是：

<uses-sdk 
    android:minSdkVersion="8" 
    android:targetSdkVersion="15" /> <!-- You need a target 

而且這部分應該來的<uses-sdk>標籤後：

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

Answer 2

你已經創建了你是storring文件的文件夾？ （使用mkdirs()）
