I am using Android studio 2.3.1 on windows 10. When I tried to run the app on device, when my device is connected to android studio, then I am able to run the app. But when I tried to install its debug or release apk on android phone then it is getting installed but while opening the app it gives following error:

Any help will be appreciated. My gradle code

apply plugin: 'com.android.application'

android {
    compileSdkVersion 25
    buildToolsVersion "25.0.2"
    defaultConfig {
        applicationId "package_Name"
        minSdkVersion 15
        targetSdkVersion 25
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support:appcompat-v7:25.3.1'
    compile 'com.android.support.constraint:constraint-layout:1.0.2'
    compile 'com.android.support:design:25.3.1'
    testCompile 'junit:junit:4.12'
}

May be the _"package Name"_ that should be `com.example.SomeClassName` instead of the package name containing white spaces. — Shashanth, Apr 27 '17 at 04:52
@ASK refer [this](http://stackoverflow.com/q/27698287/5180017) StackOverflow thread. — Shashanth, Apr 27 '17 at 05:00
Please check that it is searching for the path package_name/SplashActivity, But in zip file of apk the path is changing "package_name-1/SplashActivity" `Caused by: java.lang.ClassNotFoundException: Didn't find class **"com.packagename.fb.SplashActivity"** on path: DexPathList[[zip file **"/data/app/com.packagename.fb-1/base.apk"]**,nativeLibraryDirectories=[/vendor/lib, /system/lib]]` — ASK, Apr 27 '17 at 05:05
@DileepPatel Thank you .. Your Solution worked... (Uncheck instant run) — ASK, Apr 27 '17 at 05:42

You can solve this with just "Build (tab) / Build APK" instead of Run 'app'

@ASK could you please clean your project and rebuild it. This is the error mostly obtained when your apk is not properly created

Your package name should not contain space as from your code their is space in the package name

Please change it to like package.name

The problem might have occurred because you have you might have exceeded the 64k method limit.

You should consider enabling multidex in your app.

defaultConfig {
    ...
    ...

    // Enabling multidex support.
    multiDexEnabled true
}

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

Also add this to manifest

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
   package="com.example.android.multidex.myapplication">
   <application
       ...
       android:name="android.support.multidex.MultiDexApplication">
       ...
   </application>
</manifest>

I apply your solution but it is not working. Please look at line: `Caused by: java.lang.ClassNotFoundException: Didn't find class ** "com.packagename.fb.SplashActivity" ** on path: DexPathList[[zip file ** "/data/app/com.packagename.fb-1/base.apk"] **,nativeLibrary‌Directories=[/vendor‌/lib, /system/lib]]` – ASK Apr 27 '17 at 05:18
Your package name seem to have some anomaly here. Didn't find class ** **"com.packagename.fb.SplashActivity"** and **"/data/app/com.packagename.fb-1/base.apk"** – Chetan Ashtivkar Apr 27 '17 at 05:29

Uncheck Instant Run.. How to do this:

Open the Settings or Preferences dialog: On Windows or Linux, select File > Settings from the menu bar. On Mac OSX, select Android Studio > Preferences from the menu bar.
Navigate to Build, Execution, Deployment > Instant Run.
Uncheck the box next to Restart activity on code changes.
