Given calling package android does not match caller's uid #4639

By any chance, is the device rooted? #1606 |

Nope |

Having exact same issue. OS: Windows 11 Note: DevTools Android App used to enable Developer options and USB debugging (https://play.google.com/store/apps/details?id=cn.trinea.android.developertools&pcampaignid=web_share) [server] INFO: Device: [ONYX] ONYX NoteAir2P (Android 11) ERROR: Could not retrieve device information |

Check in your system settings or developer options if there is an option to give a permission related to clipboard. |
|
Just had a dig through and can't find anything in any settings related to clipboard. |
|
It seems (if you don't need audio) |

Same as #4349 (comment) (I don't know the cause) |

I found a solution for this on my Vivo Y21T, I had to download the older version of scrcpy which is v2.2 for now! And fsr, the newer versions don't work on mine and I had this similar error too but this thingy worked for me ^w^ |
|
2.2 works for you, what about 2.3? |

Not professional android developer, just learning it for interest. The cause of all issues related to Because the manger is initialized somewhere(i don't look into it) with "android" system context, I tried to patch the context in the manger. But after changing context, it gives me that it can't find the app. Because scrcpy is not a app, it can't pass through the getContentResolver's permission check. But, after looking into the However, due to the lack of understanding of Android I still not override the release method in ApplicationContentResolver properly (even though it seems to work fine), so there might still be some issues in my code. And also i use special android sdk, I share the idea here first. If want to set image to clipboard, it also needs a contentResolver: There may be some mistakes in this paragraph, because I did it some time ago, and now I have forgotten it a little, and my English is not very good, I have tried to decrease mistakes. |

Today, I take a look at the process of invoking system services and made some additions. The system obtains system services through My solution here is to intercept and reflectively modify the internal context in the manager by overriding

thanks, your server binary is ok on Android15(Xiaomi 15),but when i use your code to compile my own server binary, audio is broken again, and i cannot use |
Any error output?
Maybe need to add scrcpy/server/build_without_gradle.sh Lines 53 to 61 in eff5b4b |

this is compile error I will provide the runtime error log for you later. It is probably still a uid 2000 problem. I guess it is a problem with the IContentProvider definition |
