How

Google added some restrictions if you want to sideload the app to install it on other Android devices.

The Google Recorder app checks for the com.google.android.feature.PIXEL_2017_EXPERIENCE system feature to ensure that it is running on Pixel 2 or later phones.

If the system feature doesn't exist, it throws an error and the app exits immediately.

  • pseudocode by decompiling / analysing the com/google/android/apps/recorder/ui/application/RecorderApplication.java file
package com.google.android.apps.recorder.ui.application;

import android.app.Application;

public class RecorderApplication extends Application {
    // …
    public void onCreate() {
        super.onCreate();
        if (isDevBuild() || getPackageManager().hasSystemFeature("com.google.android.feature.PIXEL_2017_EXPERIENCE")) {
            // …
            return;
        }
        throw new IllegalStateException("Cannot start Recorder on unsupported device");
    }
    // …
}

This patch replaces the com.google.android.feature.PIXEL_2017_EXPERIENCE string with android.hardware.microphone that every phone / Android device should have this system feature if the device can record audio,
so that the patched app will only check for the android.hardware.microphone system feature, and won't exit immediately.

STR1="com.google.android.feature.PIXEL_2017_EXPERIENCE"
STR2="android.hardware.microphone"
