Pushing without compiling

Here you go, just put this in a C# script in Assets/Editor.

The first time it asks you for the locations of the android debug bridge exe and the apk file. These are stored in the PlayerPrefs for subsequent runs.

P.S. I tried to post this as a comment, but the formatting was crap.

 using System;
 using System.Diagnostics;
 using System.IO;
 using UnityEditor;
 using UnityEngine;
 using Debug = UnityEngine.Debug;
 
 public class BuildPlayer : MonoBehaviour {
  [MenuItem("Build/Push To Android")]
  public static void PushToAndroid() {
  string apkLocation = PlayerPrefs.GetString("APK location");
  if (string.IsNullOrEmpty(apkLocation) || !File.Exists(apkLocation))
  apkLocation = EditorUtility.OpenFilePanel("Find APK", Environment.CurrentDirectory, "apk");
  if (string.IsNullOrEmpty(apkLocation) || !File.Exists(apkLocation)) {
  Debug.LogError("Cannot find .apk file.");
  return;
  }
  PlayerPrefs.SetString("APK location", apkLocation);
 
  string adbLocation = PlayerPrefs.GetString("Android debug bridge location");
  if (string.IsNullOrEmpty(apkLocation) || !File.Exists(adbLocation))
  adbLocation = EditorUtility.OpenFilePanel("Android debug bridge", Environment.CurrentDirectory, "exe");
  if (string.IsNullOrEmpty(apkLocation) || !File.Exists(adbLocation)) {
  Debug.LogError("Cannot find adb.exe.");
  return;
  }
  PlayerPrefs.SetString("Android debug bridge location", adbLocation);
 
  ProcessStartInfo info = new ProcessStartInfo {
  FileName = adbLocation,
  Arguments = string.Format("install -r \"{0}\"", apkLocation),
  WorkingDirectory = Path.GetDirectoryName(adbLocation),
  };
  Process.Start(info);
  }
 }

Neat script. Makes it really fast to test an apk-only build on the phone.

Has anyone made a script that installs an obb-expansion file as well? I tried adding code for .obb to be handled the same as the apk-file, but that did not work out. ,Neat script. Makes it so fast to install an apk-only build.

How would I go about to install a build with an .obb-expansion file? I tried adding an obb-file the same way as the .apk-file was handled, but that did not work. The obb file is disregarded.

Has anyone made a script to install both apk and obb files?

macOS fixed script (Unity 2019.4):

 using System;
 using System.IO;
 using System.Diagnostics;
 
 using UnityEngine;
 using UnityEditor;
 
 public class AndroidAPKInstaller: MonoBehaviour
 {
     [MenuItem("File/Install APK to Android")]
     public static void PushToAndroid()
     {
         string apkLocation = PlayerPrefs.GetString("APK location");
         if (string.IsNullOrEmpty(apkLocation) || !File.Exists(apkLocation))
         { 
             apkLocation = EditorUtility.OpenFilePanel(
                 "Find APK", Environment.CurrentDirectory, "apk");
         }
 
         if (string.IsNullOrEmpty(apkLocation) || !File.Exists(apkLocation))
         {
             UnityEngine.Debug.LogError("Cannot find .apk file.");
 
             return;
         }
 
         PlayerPrefs.SetString("APK location", apkLocation);
 
         string adbLocation = EditorPrefs.GetString("AndroidSdkRoot")
             + "/platform-tools/adb";
 
         string command = "install -r " + apkLocation;
 
         print($"{adbLocation} {command}");
 
         ProcessStartInfo info = new ProcessStartInfo
         {
             FileName = adbLocation,
             Arguments = command,
             WorkingDirectory = Path.GetDirectoryName(adbLocation),
         };
 
         Process.Start(info);
     }
 }
