try this

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.info.androidapp" >

    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="app"
        android:supportsRtl="true"
        android:theme="@style/AppTheme" >

        <activity
            android:name=".SplashActivity"
            android:label="app"
            android:theme="@android:style/Theme.Holo.Light.NoActionBar.Fullscreen">

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

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

        <!-- Login activity -->
        <activity
            android:name=".LoginActivity"
            android:label="app"
            android:theme="@android:style/Theme.Holo.Light.NoActionBar.Fullscreen">

        </activity>

        <activity
            android:name=".listActivity"

            android:theme="@android:style/Theme.Holo.Light.NoActionBar.Fullscreen">

        </activity>

</manifest>

your Main Launcher activity always should be only ONE Activity.

After searching it for so long what helped me was.

1) File -> Sync Project with Gradle Files.

Or

This helped me too.

2) Uninstalling the previous installed application from emulator/mobile and re-run it and install it again.

回答3:

I had to uninstall the app for all users.

If you have multiple users (e.g. a kids mode) on your device, uninstalling the app from homescreen only removes the app form the current user.

Go to Settings -> Apps -> (Your App) -> Open Popup Menu (by clicking on the three dots in top right corner) -> Uninstall for all Users

回答4:

Uninstall your app via 'adb' in the terminal: adb uninstall com.example.yourapp

回答5:

In build.gradle, the line:

 apply plugin: 'android-library'

needs changed to:

apply plugin: 'android'

Edit:

Solution is deprecated. Please use this:

apply plugin: 'com.android.application'

回答6:

Include the applicationId configuration in build.gradle if it doesn't already exist.

android {
    compileSdkVersion 18
    buildToolsVersion '19.0.0'

    defaultConfig {
        applicationId 'com.myapp.app'
        minSdkVersion 11
        targetSdkVersion 19
        versionCode 1
        versionName "1.0"
    }
}

回答7:

The solution to my problem was to uninstall an app from the app (Settings) folder in android because the app was just disabled.

回答8:

I thing other solutoions will work fine for few user in my case i am using android 9 and i have multi user option enabled for system, it automatically install application for guest user, so goto
Settings>Apps>Concern App
And you will see uninstall for all user option at the top Option Menu. Uninstall and everything will work fine.

回答9:

in my case this error sparsely appears in one project only and I can resolve it only uninstalling the app. the simplest way is to use Gradle:

ProjName->Tasks->install->uninstallAll
