我正在嘗試將JPG圖像寫入外部SD卡。但是,我得到System.err FileNotFoundException: /mnt/sdcard/test.images/temp/savedImage (no such file or directory)
。創建該目錄似乎也失敗了,並在LogCat中給出了false
,而且在我的SD卡上查看時也無法看到該文件夾。嘗試寫入外部SD的Android錯誤
我的代碼如下:
if(Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED)) {
File folder = new File(Environment.getExternalStorageDirectory() + "/test.images/temp");
try {
if(!folder.exists()){
boolean dir = new File(Environment.getExternalStorageDirectory() + "/test.images/temp").mkdir();
Log.v("creating directory", Boolean.toString(dir));
}
File imageOutputFile = new File(Environment.getExternalStorageDirectory() + "/test.images/temp", "savedImage");
FileOutputStream fos = new FileOutputStream(imageOutputFile);
Image.compress(Bitmap.CompressFormat.JPEG, 100, fos);
fos.close();
} catch (Exception e) {
e.printStackTrace();
}
}
我有權<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
在清單中,並已清理和重建。
