Content Resolver: Need some real help on a basic app

[Pol Denais]

Hi All,
Need some big help on a basic app.

I have the content URI for a content provider and in a toast popup that displays the content from the URI.

I need to change this to a text view, and also I need to put in some code to AES decrypt (256 bytes) the PASSWORD values. I have the key already.

public void showAllpasswords(View view) {

        // Show all usernames & Passwords

        String URL = "content://com.my.pwd.contentprovider/pwds";

        Uri pwd = Uri.parse(URL);

        Cursor c = getContentResolver().query(pwds, null, null, null, "_id");

        String result = "PwdManager Results:";



        if (!c.moveToFirst()) {

            Toast.makeText(this, result+" no content yet!", Toast.LENGTH_LONG).show();

        }else{

            do{

                result = result + "\n" + c.getString(c.getColumnIndex(Passwordprovider.NAME)) +

                " with id " +  c.getString(c.getColumnIndex(Passwordprovider.ID)) +

                " has password: " + c.getString(c.getColumnIndex(Passwordprovider.PASSWORD));

            } while (c.moveToNext());

            Toast.makeText(this, result, Toast.LENGTH_LONG).show();
            
            }

I'll try to answer.

(A)
In the line 9: Cursor c = getContentResolver().query(pwds, null, null, null, "_id");

In this line the variable pwds should be pwd, I think. The first argument the method takes is a Uri. Or, is pwds altogether another variable defined elsewhere.

(B)

I have the content URI for a content provider and in a toast popup that displays the content from the URI.
I need to change this to a text view,

The value of the result in the Toast is displayed using the code in line 31: Toast.makeText(this, result, Toast.LENGTH_LONG).show();

To show the result in a TextView:

- Define a TextView in the UI XML / layout file. For example,
<TextView            android:id="@+id/result_text"            android:layout_height="wrap_content"            android:layout_weight="wrap_content"  />

- In the Java code:
TextView resultTextView = (TextView) findViewById(R.id.result_text);
resultTextView.setText(result);

In case you need the output as a list, you need to work with a ListView.

(C)

also I need to put in some code to AES decrypt (256 bytes) the PASSWORD values. I have the key already.

I found this link which has some example code, AES encrypt/decrypt example: https://howtodoinjava.com/security/java-aes-encryption-example/

Thanks Prasad. I will try the above. In regards to printing a file that is stored by another application would you know how? I have the file path.

Thanks Prasad.

You are welcome.

In regards to printing a file that is stored by another application would you know how? I have the file path.

I think you should post a new message with the question. Also, you may want to provide more information regarding that: like what are the contents of the file and what is it you are planning to print, etc.
