sorry for the very late response, i couldn't really understand what was i supposed to do in the blog could you explain to me on what to do? (my honor phone is not andriod 13 and yet it doesn't work) |

@blazeking101 Please test this version and report if this works for you: #3862 (comment) |

So on current AOSP public void startRecording()
throws IllegalStateException {
if (mState != STATE_INITIALIZED) {
throw new IllegalStateException("startRecording() called on an "
+ "uninitialized AudioRecord.");
}
// start recording
synchronized(mRecordingStateLock) {
if (native_start(MediaSyncEvent.SYNC_EVENT_NONE, 0) == SUCCESS) {
handleFullVolumeRec(true);
mRecordingState = RECORDSTATE_RECORDING;
}
}
}On your device, the code has been modified by the vendor: public void startRecording() throws IllegalStateException {
if (this.mRecordSource != 5) {
try {
Context context = ActivityThread.currentApplication();
Objects.requireNonNull(context);
String appName = context.getPackageManager().getPackageInfo(context.getPackageName(), 0).applicationInfo.loadLabel(context.getPackageManager()).toString();
String action = this.mRecordSource == 4 ? "开启通话录音" : "本地录音";
HwFrameworkFactory.getHiLog().authPrintf(3, 218114827, TAG, appName, "android.audiorecord", ActivityThread.currentPackageName(), "AudioRecord.startRecording", action, new Object[0]);
} catch (PackageManager.NameNotFoundException e) {
Log.e(TAG, "appName not found");
}
}
if (this.mState != 1) {
throw new IllegalStateException("startRecording() called on an uninitialized AudioRecord.");
}
if (HwDeviceManager.disallowOp(30)) {
HnMediaFactory.getHnAudioRecord().showDisableMicrophoneToast();
throw new IllegalStateException("microphone has been disabled.");
}
synchronized (this.mRecordingStateLock) {
if (native_start(0, 0) == 0) {
handleFullVolumeRec(true);
this.mRecordingState = 3;
HwAudioServiceManager.checkRecordActive(this.mRecordSource);
HwAudioServiceManager.sendRecordStateChangedIntent(this.mRecordingState);
} else {
HwAudioServiceManager.sendRecordStateChangedIntent(-1);
}
}
}It attempts to get information about the application package 😕 Scrcpy could not be run as an application (otherwise it would not get shell permissions), so it fails. For now, I don't see any solution to bypass this piece of code and make it work on your device. |

I think it will work. I tried this minimal code: Looper.prepareMainLooper();

var systemMain = systemMainMethod.invoke(null);
Objects.requireNonNull(systemMain);
var getSystemContextMethod = systemMain.getClass().getDeclaredMethod("getSystemContext");
var systemContext = (Context) getSystemContextMethod.invoke(systemMain);
Objects.requireNonNull(systemContext);
var packageManager = systemContext.getPackageManager();
var packageInfo = packageManager.getPackageInfo("com.android.shell", 0);
System.out.println(packageInfo.applicationInfo.loadLabel(packageManager));It prints |

Thanks very much! and This time it report this: |

OK, the result is as expected 👍 Thank you for the test. I'll work on a proper fix on |
|
Aha, this is what i should do, and I'm very happy, It also made the process of my first bug report enjoyable. Dalao, I am extremly grateful for the effort you had done for a better sortware user experience! (my English is poor , sorry for that) |

Arf, passing the system context as base in (That's just a log in the system code, nothing is thrown.) Maybe I should pass it only if the manufacturer is not Xiaomi 😕 @TheTouYu By the way, could you post the result of: |

@yume-chan Oh, providing a base context might also impact Vivo phones: #3757 (comment) |

Thank you for your quick test. I'm surprised that it does not work. Does #4015 (comment) work for you? |

let me try, wait a moment |

oh no, |
Audio did not work on Honor devices. To make it work, a system context must be set as a base context of FakeContext (so that a PackageManager is available), and a current Application must be initialized. These workarounds must not be applied for all devices, because they might cause other issues.

OK, there was some confusion because the first patches were applied on So, maybe this one will work (1c2d4b1 branch

sorry, this version still no work ( |

Ok, I will need more time then (maybe this evening or tomorrow) :/ Could you just confirm that #4015 (comment) still works (if you replace the binary in your v2.0 release)? |

congratulations！ it‘s ok! ( $ ^^ $ ) |

So it works for Honor devices and also for Vivo devices (#3805 (comment)). Let's merge it: fb21bbf |

FakeContext used ActivityThread.getSystemContext() as base context only in some cases, because it caused problems on some devices: - warnings on Xiaomi devices [1], which are now fixed by b8c5853 - issues related to Looper [2], which are solved by just calling Looper.prepare*() Therefore, we can now always assign a base context, which simplifies and helps to solve camera issues on some devices (#4392).

Hi, I have the same issue on my Realme phone. Here's the console output: |

Sorry for the trouble, audio works when I start scrcpy after unlocking my phone. |
