Question

I get this error everytime I try to use my content provider to insert a URI. Here is the method:

private void sample() {
    ContentValues values;

    values = new ContentValues();
    values.put(Formulas.TITLE, "Formula1");
    values.put(Formulas.FORMULA, "someformula");
    getContentResolver().insert(getIntent().getData(), values);

    values = new ContentValues();
    values.put(Formulas.TITLE, "Formula2");
    values.put(Formulas.FORMULA, "someformula");
    getContentResolver().insert(getIntent().getData(), values);

    values = new ContentValues();
    values.put(Formulas.TITLE, "Formula3");
    values.put(Formulas.FORMULA, "someformula");
    getContentResolver().insert(getIntent().getData(), values);
}

Previously I set the Intent data here:

Intent intent = getIntent();
if (intent.getData() == null)
    intent.setData(Formulas.CONTENT_URI);

Here is my content URI and authority:

public static final String AUTHORITY = "com.mohit.provider.FormulaProvider";
public static final Uri CONTENT_URI = Uri.parse("content:\\" + AUTHORITY + "\formulas");

Here is the provider tag:

<provider android:name="com.mohit.provider.FormulaProvider" 
        android:authorities="com.mohit.provider.FormulaProvider" />

And finally the Logcat log:

What could be the problem?

Answer 1

backslashes \ look strange in a URI, try // resp. /
