java - 未知 URL 内容 :Unknown URL content:\com. mohit.provider.FormulaProvider\formulas

Question

每次我尝试使用我的内容提供程序插入 URI 时都会收到此错误。方法如下:

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);
}

之前我在这里设置 Intent 数据:

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

这是我的内容 URI 和权限:

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

这是提供者标签:

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

最后是 Logcat 日志:

可能是什么问题？

Answer 1

反斜杠\在 URI 中看起来很奇怪，尝试//resp。/
