Activity class {.....SplashActivity} does not exist

Question

I got these error while run project on device:

Launching application:.Splash_Activity.
DEVICE SHELL COMMAND: am start -n ".Splash_Activity" -a android.intent.action.MAIN -c android.intent.category.LAUNCHER
Starting: Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] cmp=.Splash_Activity }
Error type 3
Error: Activity class {.Splash_Activity} does not exist.

I check my Android-Manifest file it is like

 <activity
        android:name=".SplashActivity"
        android:screenOrientation="portrait"
        android:theme="@android:style/Theme.NoTitleBar.Fullscreen">

        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
        
</activity>

and Gradle is like:

apply plugin: 'com.android.library'

android {
    compileSdkVersion 21
    buildToolsVersion "21.0.2"

    defaultConfig {
        minSdkVersion 14
        targetSdkVersion 21
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}
allprojects {
    tasks.withType(JavaCompile) {
        options.compilerArgs << "-Xlint:deprecation" << "-Xlint:unchecked"
    }
}

repositories {
    jcenter()
}


dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    compile 'com.android.support:cardview-v7:+'
    compile 'com.google.android.gms:play-services:4.3.+'
    compile files('libs/GraphView-3.1.3.jar')
    compile files('libs/google-play-services.jar')
    compile files('libs/android-support-v4.jar')
    compile files('libs/bolts-android-1.1.2.jar')
    compile 'com.github.navasmdc:MaterialDesign:1.+@aar'
    compile files('libs/nineoldandroids-2.4.0.jar')
    compile 'com.android.support:appcompat-v7:22.0.0'
}

I also try so much by changing the package name and so on.. What should I do to solve this issue?

Answer 1

2018... make sure the device has the app completely uninstalled. Go to your Apps in your settings and delete the reference to the app your trying to install.

Answer 2

To resolve this issue:

1. Clean the Project
2. Deleted the Build directory
3. Restart Android studio
4. Rebuild the Project
5. Run

I think the key is to restart your IDE.

Or Try adding

com.package.name.SplashActivity

Here change the package name accordingly

Answer 3

If app was installed before then you need to be sure app deleted for all users. (Old versions of Android cause that error.)

You could check it from phone Settings -> Apps and Notifications -> Application Informations -> Your App Name then click delete for all users button from right up corner menu.
