Может ли кто-нибудь помочь в этом? Благодаря!

Answer 1

Похоже, вы переименовали свой класс Activity в «Test», не изменяя его в своем AndroidManifest.xml. Вы, вероятно, нужно изменить линию от этого:

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

Для этого:

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