Answer 1

I had same problem by using Android Studio 2.3.2 and solved the issue by adding these codes in gradle file.

defaultConfig {
    ...
    minSdkVersion 15
    targetSdkVersion 25
    ...

    // Enabling multidex support.
    multiDexEnabled true
}

 dependencies {
     compile 'com.android.support:multidex:1.0.0'
 }

In case you are running a device with MIUI, go to Developer Settings > Turn on MIUI optimization and turn it off.

You will then need to restart your device and recompile the code.

Instant Run should then work again

Answer 3

Instant Run Documentation:

To start using Instant Run, you also need to change the build variant to a debug version of your app and deploy it to a target device running Android 5.0 (API level 21) or higher. To learn about more techniques that speed up your build, read Optimize Your Build Speed

so make sure your build variant is set to 'debug'.
