Answer 1

No Launcher activity found! 

Votre fichier manifeste doit avoir une activité en tant que lanceur d'applications ...

<activity 
android:name=".MainActivity" 
android:label="@string/title_activity_main" > 

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

</activity> 

Answer 2

Je pense que vous devez définir une activité de lancement.

<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
    package="main.java" 
    android:versionCode="1" 
    android:versionName="1.0" > 

    <uses-sdk 
     android:minSdkVersion="16" 
     android:targetSdkVersion="15" /> 

    <application 
     android:icon="@drawable/ic_launcher" 
     android:label="@string/app_name" 
     android:theme="@style/AppTheme" > 
     <activity 
      android:name=".MainActivity" 
      android:label="@string/title_activity_main" > 
     <intent-filter> 
      <action android:name="android.intent.action.MAIN" /> 
      <category android:name="android.intent.category.LAUNCHER" /> 
     </intent-filter> 
     </activity> 
    </application> 

</manifest> 

Answer 3

Insérer <category android:name="android.intent.category.LAUNCHER" /> dans votre balise d'activité, cela prendra soin de question que je suppose.
