Android 6.0写入外部SD卡 [英] Android 6.0 Write to external SD Card

问题描述

我已尝试将所有内容写在Android 6.0上的外部SD卡上，但无法在上面写.

I tried everything to write on external SD card on Android 6.0, but I am not able to write on it.

我对stackoverflow进行了研究，发现了很多东西，但是没有用.这是我的代码

I did research on stackoverflow and found lot of things but none works. Here is my code

String extPath = System.getenv("SECONDARY_STORAGE") + "/Android/data/com.gvm.externalstorage.externalstoragetest/";
File file = new File(extPath,"myFiles");

            if (!file.exists()) {
                boolean dirResult = file.mkdirs();
                Log.e("Directory Exist", dirResult + " Directory created");
            } else {
                Log.e("Directory Exist", "Exist");
                Log.e("Direcotry Path",file.getAbsolutePath());
            }
            //String displayname = fileName.replace("%20", " ");
            File outputFile = new File(file, "mytest5.txt");
            outputFile.createNewFile();

此代码在Android 5.0上有效，但在Android 6.0上无效.

This code works on Android 5.0 but not on Android 6.0.

然后我也尝试了该路径，这给了我权限错误，我还为运行时权限设置了所有权限和托管代码.

Then I tried this path as well, and that gives me permission error, I have set all permission and managed code for runtime permission as well.

/mnt/media_rw/6AC9-083B

File write failed: java.io.IOException: open failed: EACCES (Permission denied)

如果有人可以帮助我，那将是非常棒的事情，因为自最近三天以来我一直在尝试这样做.

If anyone can help me it would be great as I am trying this since last 3 days.

谢谢， Anvesh

推荐答案

经过长时间的努力，我找到了解决方案.在Android 6.0中，不会始终使用以下命令为您提供SD卡路径:

After long hard work I figured out a solution. In Android 6.0 it's not going to give you SD Card path always using this:

System.getenv("SECONDARY_STORAGE") 

或这个

Environment.getExternalStorageDirectory()

所以我使用此文件检索了外部SD卡路径

So I retrieved external SD Card path using this

File[] fs = context.getExternalFilesDirs(null);
            String extPath = "";
            // at index 0 you have the internal storage and at index 1 the real external...
            if (fs != null && fs.length >= 2)
            {
                extPath = fs[1].getAbsolutePath();
                Log.e("SD Path",fs[1].getAbsolutePath());
            }

其余所有内容均应保持许可状态.

Rest everything will remain same for permission and all.

感谢那些帮助过我的人.
