SD卡的内容不可见DDMS文件浏览器的Andr​​oid 6.0 [英] Sdcard Content not visible in DDMS File Explorer Android 6.0

问题描述

在Android 6.0已经改变了它的方式来管理SD卡安装，并且不会让节目的权利。

Android 6.0 has changed its way to manage sdcard-mounting and that doesn't let show right.

直到5.x中，我们可以在层次结构下获得通过DDMS透视（Eclipse中）和SD卡内容

Until 5.x we could access to the SDCard Contents via DDMS Perspective (Eclipse) under the hierarchy

到/ mnt /壳/...

/mnt/shell/...

和现在根据在

/ SD卡/

我看不到DDMS下，但在PC或其他应用程序（如天文）此目录的任何内容。

I can't see any content of this directory under DDMS but in the PC or other Apps (like Astro).

我应该在Eclipse（DDMS），以便能够看到的内容？设置

推荐答案

启动的Andr​​oid 6.0，第三方应用程序都没有能够看到SD卡的内容。

Starting Android 6.0, third-party apps have no ability to see SDCard content.

在Android的6.0，第三方应用没有访问sdcard_r和
  sdcard_rw的GID。相反，可通过仅安装控制
  在地方，该应用相应的运行时视图。跨用户
  交互使用的是大家GID受阻。

In Android 6.0, third-party apps don’t have access to the sdcard_r and sdcard_rw GIDs. Instead, access is controlled by mounting only the appropriate runtime view in place for that app. Cross-user interactions are blocked using the everybody GID.

至于其他信息，在Android 6.0推出的 可采用的存储 和 运行权限 这施加限制上与存储装置之间的相互作用。

As additional information, Android 6.0 introduces Adoptable Storage and Runtime Permissions which impose restrictions on the interaction with a storage of device.

至于是如何从DDMS可以访问一个文件到Android 6.0。这个动作是不允许的。如果你需要从你的应用程序可以访问文件，您可以使用此源$ C ​​$ C例如：

Regarding how get access to a file from DDMS to Android 6.0. This action is not allowed. If you need to get access to file from your app you can use this source code example :

   @Override

        mPermissions = new String[] { Manifest.permission.WRITE_EXTERNAL_STORAGE };
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
           boolean isAllow = ContextCompat.checkSelfPermission(this, mPermissions[0]) == PackageManager.PERMISSION_GRANTED;
           if (!isAllow) {
              if (shouldShowRequestPermissionRationale(mPermissions[0])) {
                 // There is you need to display confirmation dialog about why you need to get this permission. 
                 if (confirm("You need to copy database to  device's storage") == YES) {
                     requestPermissions(mPermissions, REQUEST_CODE_ASK_PERMISSIONS)   
                  } else {
                     // User does not agree with your requirements
                     // You should decide how the app will work in this case.

                  return;
              }
              requestPermissions(mPermissions, REQUEST_CODE_ASK_PERMISSIONS);
           }

        } else {
          runTheApp();
        }
   }

 @Override
 public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
            switch (requestCode) {
                case REQUEST_CODE_ASK_PERMISSIONS:

                        if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
