Instant run doesn't work anymore for my phone

Question

I have 4.4.4 (19) Android and I can't use instant run with new version (2.3) of Android Studio:

Why did they do it? It worked on the version before this one.

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.3.0'

...

apply plugin: 'com.android.application'

android {
    compileSdkVersion 25
    buildToolsVersion "25.0.2"
    defaultConfig {
        applicationId ***
        minSdkVersion 16
        targetSdkVersion 25
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        vectorDrawables.useSupportLibrary true
        renderscriptTargetApi 25
        renderscriptSupportModeEnabled true
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    ***
}

@JasonC in his case this new button "instant run" is active, but app crashes on running, in my case the button isn't even active (I can't click it) — user25, Mar 11 '17 at 23:44
Add the Gradle file, please... The error is right there. Can't run on API 19 — OneCricketeer, Mar 11 '17 at 23:50

(emphasis mine)

In Android Studio 2.3 and higher, Instant Run significantly reduces the time it takes to update your app with code and resource changes. After deploying your app to a target device running Android 5.0 (API level 21) or higher, you can click Apply Changes to push certain code and resource changes to your running app without building a new APK—and, in some cases, without even restarting the current activity

Android | Instant Run

Note You can still set the targetSdkVersion and compileSdk version to the latest API levels without affecting the majority of your code. (minus any deprecated methods)

I don't understand what was slow in old "instant run" feature and why changed it so now it doesn't even support 4.* OS... – user25 Mar 12 '17 at 00:05
Because 5.0 introduced the ART runtime. https://developer.android.com/about/versions/android-5.0-changes.html – OneCricketeer Mar 12 '17 at 00:07
why didn't they left old "Instant run" for 4.* and just use new one for older versions... – user25 Mar 12 '17 at 00:14
I'm not on the Android Development team. You're asking the wrong person. – OneCricketeer Mar 12 '17 at 00:27
I know, I'm just saying it.. mb someone of them will see it. but what about gradle file? – user25 Mar 12 '17 at 00:30
I just wanted to see what versions you had set. But doesn't really matter, just that you are running API < 21 on the device is why it is disabled – OneCricketeer Mar 12 '17 at 00:44

If you still not find solution then just go one way.Probably it work for you.

Update your sdk with Platform tools whatever Device you want to run.

Instant need platform tools.

Like nougat need 24.

Thanks hope this will help you.
