There are customized parameters that are available for various devices (each OEM and its own parameters), which can be set here and maybe even via JNI ( here and here), but I don't get where to get this information from (meaning which pairs of key-value are available). It stays on the value of "2" during call, which is MODE_IN_CALL. I was thinking of maybe change the "channel" of where the call is being used, this way, but it doesn't work. There is an API of "setMode" here, but it doesn't seem to change upon calling it. Or, it's just too complicated for everyone (especially for users), so they generalize the names. Those apps probably do not want others to understand what those configurations mean, so they put general names. One example is " Automatic Call Recorder" which has "configuration" (10 values to choose from, first is "default") and "method" (5 vales to choose from, first is "default"). Most third party apps only offer the AudioSource tweaking, but some (like "boldbeast") do offer more.

The second doesn't even seem to work on Android 6.0.1 device, which it's supposed to support.Īykuttasil - CallRecorder sample and axet - android-call-recorder sample - both, just like on my POC, don't have any tweaking except for AudioSource, and because of this they fails to record on some cases, such as OnePlus 2 output-audio of outgoing calls. These 2 old sample projects : rvoix, esnyder-callrecorder, both fail to actually record. This "ViktorDegtyarev - CallRecLib" SDK, which doesn't seem to work at all, and crashes on various Android versions To let you try my POC of call recording, I've published an open source github repository here, having a sample that will record a single call, and let you listen to the most recent one, if all works well. On Galaxy S7 with Android 8, I've failed to get sound of the other side for outgoing calls AND incoming calls (even with MIC and speaker), no matter what I did, yet the app I've mentioned worked fine. The comment that was written there is "Sometimes prepare takes some time to complete". It works fine, and when I did something similar (wait using Handler.postDelayed for 1 second), it worked fine too. Update: I've found this sample project (also here), which for some reason sleeps for 2 seconds on the UI thread between prepare and start calls of the mediaRecorder. I'm sure I will see other issues with other Android devices, as I've tried to address this whole topic in the past. Somehow, the app I've mentioned succeeds recording it without any issues. On OnePlus 2 with Android 6.0.1, incoming calls can be recorded using VOICE_CALL, but I can't make outgoing calls be recorded there, unless I use MIC as audio source together with speaker turned on.
For some, VOICE_CALL works, and for some, others. There are some Audio recording sources we can use while preparing the recording (docs here), but sadly in each device it might be different.

Other than tons of questions of how to record calls on Android, showing that it doesn't work on all devices, I could find some interesting things. I can't find any of those of the app I've mentioned, for example. If I'm in need to create a call recording app, there is no other way than to find the various workarounds for various devices, but as it seems other apps use terms that don't appear in the API.
"change audio driver" (change audio drive settings to enable record mode 21,22,23,24,31,32,33,34") "change audio controls" ("auto change audio controls")
Has "Tune Audio Route", with the possible values of "Disabled", "Group1", "Group2", "Group3" Has "Tune Audio Effect ("auto tune a groupd of parameters"). Also shows "Alsa mode" as an option for it, for rooted devices. Shows 14 modes for non-rooted devices, and up to 34 for rooted. One such example is boldbeast Call Recorder app, which offers a lot of various configurations to change: This made various call recording apps gather as much possible information about devices and what should be done to them, and decide upon this what to do. Phone recording is not really supported on Android, yet some devices support it to some extend.
