Activity class {} does not not exist android 3.5.1(Instant run is no longer available)

Question

I am trying to create application but while debugging after several time I am getting error. Error: Activity class {com.tectibet.loginapp/com.tectibet.loginapp.MainActivity} does not exist.I tried cleaning cache and restart,rebuild and clean.

I have tried changing manifest and build.gradle package name as well. also I went through Error type 3 Error: Activity class {} does not exist but it didt work out.

<application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity android:name=".HomeActivity"></activity>
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

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

Application is not launching at all displaying error like activity is does not exist(even though i does).

Error while executing: am start -n "com.tectibet.loginapp/com.tectibet.loginapp.MainActivity" -a android.intent.action.MAIN -c android.intent.category.LAUNCHER Starting: Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] cmp=com.tectibet.loginapp/.MainActivity } Error type 3 Error: Activity class {com.tectibet.loginapp/com.tectibet.loginapp.MainActivity} does not exist.

Option 1:

In build.gradle, the line:

apply plugin: 'android-library'

needs changed to:

apply plugin: 'com.android.application'

Option 2:

This is how i fixed it. go to gradle > Tasks > Install > UninstallAll
