Subject: [PATCH] Fix LaunchAnyWhere in AppRestrictionsFragment
|
|
|
|
If the intent's package equals to the app's package, this intent
|
|
will be allowed to startActivityForResult.
|
|
But this check is unsafe, because if the component of this intent
|
|
is set, the package field will just be ignored. So if we set the
|
|
component to any activity we like and set package to the app's
|
|
package, it will pass the assertSafeToStartCustomActivity check
|
|
and now we can launch anywhere.
|
|
|
|
Bug: 223578534
|
|
Test: robotest and manual verify
