AAPT2 error: check logs for details AppThene

Question

I am facing an AAPT2 error, this is due to the upgrade of Android Studio.

After a lot of Internet Search, i figured it must be something with the xml in the Android Manifest. I tried different things, chanching the structre, but not sucessful yet. Do have experience with the AndroidManifest.xml and AAPT2? Here's mine

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="ch.workouttracker"
    android:versionCode="1"
    android:versionName="1.0" >

I can't find the problem. Maybe you can.

Add `android.enableAapt2=false` in gradle file for quick fix. — Abhi, Apr 07 '18 at 12:16
this is not a fix, just a workaround and it is deprecated by now — Christian Bohli, Apr 07 '18 at 12:19
Yes it is a workaround. You can run `assembleDebug` in gradle console to find the specific line in XML causing the error. — Abhi, Apr 07 '18 at 12:21

Try @style/Apptheme instead of just Apptheme.

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

Does the style `AppTheme` exist in your styles.xml? – Abhi Apr 07 '18 at 12:35
No, like before the upgrade – Christian Bohli Apr 07 '18 at 12:37
Post your styles.xml – Abhi Apr 07 '18 at 12:40
– Christian Bohli Apr 07 '18 at 12:43
There you go. Just change the style name to `AppTheme` from login. – Abhi Apr 07 '18 at 12:44
Or instead use `android:theme="@style/login"` in your Manifest. – Abhi Apr 07 '18 at 12:50
