[Solved] Android Studio not installing App on device

by


The reason why you re getting the error is because you have no activity to launch the app , so in your manifest file , you should specify the launcher activity

  • This is the code
 <activity
            android:name=".activities.ControlActivity"  activity
            android:label="@string/title_activity_control"
            android:theme="@style/AppTheme.NoActionBar"></activity>
        <activity android:name=".activities.ConnectActivity"> // here specify the the
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

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