QUESTION

There was a problem saving the text in EditText to a file

Asked 2021-Jun-16 at 01:47

This code receives information from an acquaintance you want to register in editText, and then clicks finButton to save the information you receive as a file called friendlist.txt. However, the Toast message is outputted from the try-catch statement that is currently performed when finButton is pressed. Also, the checkpermission does not work, which is wrapped in a try~catch statement, but does not have output on the logcat.

And manifest.

uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"

uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"

is written.

Please let me know the solution. And this content is written with a translator, so the sentence can be strange.

when you press finButton, the logcat is shown below.

The code corresponding to the 116th line is this.

FileOutputStream outstream = openFileOutput("friendList.txt", Activity.MODE_WORLD_WRITEABLE);

The problem is that your CSS selectors include parentheses () and dollar signs $. These symbols already have a special meaning. See:

() - Are parentheses allowed in CSS selectors?
$ - [attribute$=value] Selector

You can escape these characters using a backslash \.

The issue you are having has nothing to do with templates. You cannot invoke std::async() on a member function without binding it to an instance. Wrapping the call in a lambda does the trick.
