How to create a file in an SDCARD directory
Solution 1
Try the following example:
if (!Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED)){
//handle case of no SDCARD present
} else {
String dir = Environment.getExternalStorageDirectory()+File.separator+"myDirectory";
//create folder
File folder = new File(dir); //folder name
folder.mkdirs();
//create file
File file = new File(dir, "filename.extension");
}
Don't forget to add the permission to your AndroidManifest:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
Solution 2
The problem is that mkdirs() is called on a File object containing the whole path up to the actual file. It should be called on a File object containing the Path (the directory) and only that. Then you should use another File object to create the actual file.
Solution 3
You should also have to add permission to write to external media. Add following line in the application manifest file, somewhere between <manifest> tags, but not inside <application> tag:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
Solution 4
Use This:
DocumentFile tempDir = DocumentFile.fromSingleUri(context,targetDirectoryUri);
DocumentFile newDocumentFile = tempDir.createFile(type,name);
"targetDirectoryUri" is uri of the directory you want to put the file into it. This is the only solution! After Api 19 you can not write on SDCard, so you must use DocumentFile instead File. In addition, you must also take SDCard permission. To learn how to do this and get the targetDirectoryUri, please read this.
