이것은 내 로그캣 오류이며 아래는 안드로이드 매니페스트 파일입니다. 어제 작동하고 단일 문자를 변경하지 못하고 오류가 계속 발생합니다.

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

    <uses-sdk 
     android:minSdkVersion="8" 
     android:targetSdkVersion="18" /> 

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

      android:label="@string/app_name" >

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

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

      android:noHistory="true" 
      android:screenOrientation="portrait" > 
     </activity> 
    </application> 
</manifest> 

나는 어디에서 잘못 된지 여기에서 볼 수 있습니다. Tnx에게 도움을 요청합니다.

문제는 구성이 아닌 Java 클래스에 있습니다. 대부분의 액티비티 클래스는 public 빈 생성자가 없거나 추상 클래스입니다.
