android - Coverity - contentResolver.delete() 中的显式 null 取消引用 (FORWARD_NULL)

Question

使用 delete() 语句从 ContentProvider 中删除所有行会导致 Coverity 错误。

显式取消引用空 (FORWARD_NULL)
将空指针选择传递给删除，从而取消引用。

String selection = null;
String[] selectionArgs = null;

mContentResolver.delete(MyContentProvider.MY_CONTENT_URI, selection, selectionArgs);

有什么办法可以解决这个 Coverity 问题吗？

Answer 1

According to your code the issue seems right - you forward "null"... Can you post the code of your ContentResolver Implementation?

To remove the warning you may try to use:

String selection = "";
String[] selectionArgs = new String[0];

As you may see in the source code the selection (at least) for logging is set to:

selection != null ? selection : "",
