ClipboardMonitor 2 | 3 | This is a sample Android project that monitors the system's ClipboardManager 4 | for changes and logs the clipboard text to a file. 5 | 6 | ## Update (2019-11-26) 7 | 8 | This issue is completely mitigated in Android 10 with this change: 9 | 10 | > **Limited access to clipboard data** 11 | > 12 | > Unless your app is the default input method editor (IME) or is the app that currently has focus, your app cannot access clipboard data on Android 10 or higher. 13 | 14 | https://developer.android.com/about/versions/10/privacy/changes#clipboard-data 15 | 16 | ## Security 17 | 18 | An electronic clipboard is insecure by nature. Such a system is designed to 19 | facilitate the sharing of data between applications. However, the Android 20 | ClipboardManager is so mind blowingly insecure that any application can 21 | log every piece of data that you copy. This project is designed to illustrate 22 | how trivial this is. 23 | 24 | Android developers need to be aware that anything they add to the system 25 | clipboard should be considered public data. 26 | 27 | ## Recommendations 28 | 29 | ~~The Android platform should implement a `READ_CLIPBOARD` permission or a 30 | `PasswordEditText` with a supported `PICK_PASSWORD` intent action so users 31 | have more control over what apps have access to the system clipboard.~~ 32 | 33 | The new [Autofill Framework](https://developer.android.com/guide/topics/text/autofill.html) solves these concerns in Android 8.0. 34 | 35 | ## License 36 | 37 | This code is released under the Apache 2.0 license.
