Android：捕捉和存储图片

Question

我正在学习本教程，内容是拍摄图片，显示缩略图，并将完整的图片存储在本地公共存储空间中，仅供我的应用程序使用。

问题：尝试访问应用程序的本地存储时，EACCESS（权限被拒绝

11-12 10:36:30.765    3746-3746/com.test.example.photo W/System.err﹕ java.io.IOException: open failed: EACCES (Permission denied)
11-12 10:36:30.765    3746-3746/com.test.example.photo W/System.err﹕ at java.io.File.createNewFile(File.java:948)
11-12 10:36:30.765    3746-3746/com.test.example.photo W/System.err﹕ at java.io.File.createTempFile(File.java:1013)

</application>
    <!-- PERMISSIONS -->
    <permission
        android:name="android.hardware.Camera.any"
        android:required="true" />
    <permission
        android:name="android.permission.WRITE_EXTERNAL_STORAGE"
        android:required="true" />
    <!-- android:maxSdkVersion="18" seemingly does nothing-->
</manifest>

private File createImageFile() throws IOException {
    // Create an image file name
    String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
    String imageFileName = "JPEG_" + timeStamp + "_";

    //THIS IS WHERE IT CRASHES
    File storageDir = Environment.getExternalStoragePublicDirectory(
            Environment.DIRECTORY_PICTURES);
    File image = File.createTempFile(
        imageFileName,  /* prefix */
        ".jpg",         /* suffix */
        storageDir      /* directory */
    );

    // Save a file: path for use with ACTION_VIEW intents
    mCurrentPhotoPath = "file:" + image.getAbsolutePath();
    return image;
}

谢谢你抽出时间！

而不是permission标记use uses-permission在清单中添加这个

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