Use a flag to grant a temporary URI permission.
It turns out that we can let the system to call
InputMethodService#exposeContent(InputContentInfo, EditorInfo), which
added in my previous CL [1], during the IME is calling
InputConnection#commitContent() as follows.
[IME]
InputContentInfo contentInfo = new InputContentInfo(
contentUri,
new ClipDescription(description, new String[]{mimeType}),
linkUrl);
getCurrentInputConnection().commitContent(
inputContentInfo,
InputConnection.INPUT_CONTENT_GRANT_READ_URI_PERMISSION,
null);
[App]
try {
contentInfo.requestPermission();
// Load inputContentInfo.getContentUri() here.
} finally {
contentInfo.releasePermission();
}
This gives us flexibility to let InputConnection#commitContent() do all
the magic for IME developers like other APIs such as
Context#startActivity(), rather than asking them to call one more API to
grant a temporary URI permission like a scenario where
Context#grantUriPermission() is used.
