打开失败：将图像上传到服务器时在棉花糖中出现 EACCES（权限被拒绝）

Question

我正在处理我想将图像发送到服务器的项目。当我将图像发送到服务器时，除棉花糖外的所有版本都可以正常工作。

我在从图库中选择图片时获得了许可。是否有任何特殊权限可以发送图像？

private static int PICK_IMAGE_REQUEST = 1;

if (Build.VERSION.SDK_INT <= 19) {
                Intent i = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
                startActivityForResult(i, PICK_IMAGE_REQUEST);
            } else if (Build.VERSION.SDK_INT > 19) {
                Intent i = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
                startActivityForResult(i, PICK_IMAGE_REQUEST);

            }

Answer 1

您需要请求用户的运行时权限。检查这个 link https://developer.android.com/training/permissions/requesting.html

Answer 2

可能还缺少一项 Internet 权限。

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

还要转到设置并检查是否已授予权限，因为在棉花糖中需要在运行时授予权限..

检查下方 link... https://developer.android.com/training/permissions/requesting.html

希望您的问题得到解决...

AndroidManifest.xml

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

在Activity

  private static final int REQUEST_STORAGE = 112;


  if (Build.VERSION.SDK_INT >= 23) {
    String[] PERMISSIONS = {android.Manifest.permission.WRITE_EXTERNAL_STORAGE, android.Manifest.permission.READ_EXTERNAL_STORAGE};
    if (!hasPermissions(mContext, PERMISSIONS)) {
        ActivityCompat.requestPermissions((Activity) mContext, PERMISSIONS, REQUEST_STORAGE );
    } else {
        Intent i = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
        startActivityForResult(i, PICK_IMAGE_REQUEST);
    }
} else {
    Intent i = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
    startActivityForResult(i, PICK_IMAGE_REQUEST);
}

 /*get Permissions Result*/
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    switch (requestCode) {
        case REQUEST_STORAGE: {
            if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {

               Intent i = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
               startActivityForResult(i, PICK_IMAGE_REQUEST);
            } else {
                Toast.makeText(mContext, "The app was not allowed to write to your storage.", Toast.LENGTH_LONG).show();
            }
        }
    }
}

   /*check permissions  for marshmallow*/

private static boolean hasPermissions(Context context, String... permissions) {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M && context != null && permissions != null) {
        for (String permission : permissions) {
            if (ActivityCompat.checkSelfPermission(context, permission) != PackageManager.PERMISSION_GRANTED) {
                return false;
            }
        }
    }
    return true;
}
