I was working with some libraries so I had to edit Gradle settings. Since my app wasn't working, I restored it with Local history in Android studio but It still doesn't work. Errors returned are reported here

You may have updated to AndroidX support library and the layout is referencing the old ConstraintLayout version. So you have to update the android.support.constraint.ConstraintLayout
tags to androidx.constraintlayout.widget.ConstraintLayout
in your layout XML.
Changes you have made earlier corrupted your Gradle File (the module one). It should look like this:
apply plugin: 'com.android.application'
android {
compileSdkVersion 25
buildToolsVersion "25.0.2"
defaultConfig {
applicationId "***" /*Your package name*/
minSdkVersion 15
targetSdkVersion 25
versionCode 5
versionName "1.4"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
vectorDrawables.useSupportLibrary = true
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
repositories {
jcenter()
maven { url "https://jitpack.io" }
}
dependencies {
//Your Dependencies
//Don't forget to add dependency of constraint-layout
compile 'com.android.support.constraint:constraint-layout:1.0.2'
}
Add dependency for constraint-layout. See Code
NOTE : compile has become obsolete and replaced with 'implementation' keyword so replace 'compile' with 'implementation'
so the code will be
dependencies {
//Your Dependencies
//Don't forget to add dependency of constraint-layout
implementation 'com.android.support.constraint:constraint-layout:1.1.0'
}
UPDATE: If you have upgraded to AndroidX now. Then you need to use androidx.constraintlayout.widget.ConstraintLayout instead of android.support.constraint.ConstraintLayout
use androidx.constraintlayout.widget.ConstraintLayout replace android.support.constraint.ConstraintLayout, then it worked
