This is a follow up CL to my previous CLs [1][2] that introduced
InputConnection#commitContent(InputContentInfo, Bundle) API to enable
IMEs to send a content to the target application.
With this CL, IME developers are able to temporarily expose
InputContentInfo object to the target package without permanently
granting URI permission. Although calling IMS#exposeContent() is
allowed only for the IME that is currently selected, the client is able
to request a temporary read-only access even after the current IME is
switched to any other IME as long as the client keeps InputContentInfo
object.
Here is a sample code snippet about how to use this mechanism.
[IME]
InputContentInfo contentInfo = new InputContentInfo(
contentUri,
new ClipDescription(description, new String[]{mimeType}),
linkUrl);
exposeContent(contentInfo, getCurrentInputEditorInfo());
getCurrentInputConnection().commitContent(inputContentInfo, null);
[App]
try {
contentInfo.requestPermission();
// Load inputContentInfo.getContentUri() here.
} finally {
contentInfo.releasePermission();
}
