AndroidAnnotations未找到活动

Question

Hi i've added the AndroidAnnotations and configured it; it generates the activity with the underscore _ as suffix, but when I try to lunch the app, it gives this error

   05-26 04:17:23.524: E/AndroidRuntime(5096): java.lang.RuntimeException: 
   Unable to instantiate activity
   ComponentInfo{android_app.candgo/android_app.candgo.HelloAndroidActivity_}:  
   java.lang.ClassNotFoundException: Didn't find class
   "android_app.candgo.HelloAndroidActivity_"    
   on path: /data/app/android_app.candgo-1.apk

Any suggestion about why it doesn't work

PD: I've ADT v22 PD: I've the HelloAndroidActivity_ registered at manifest

This is my manifest.xml (sorry for the delay)

  <uses-sdk android:minSdkVersion="8"
            android:targetSdkVersion="16" />

  <application android:icon="@drawable/icon" android:label="@string/app_name">
    <activity android:name="MainActivity_">
      <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
      </intent-filter>
    </activity>
  </application>
</manifest>

Answer 1

You need to add the ".apt_generated", or whichever folder AA outputs to, to your source directories listing. In Android Studio, you can find this in Project Settings -> Modules -> module_in_question -> Sources

Answer 2

you need to register the activity class(AndroidAnnotations) in your manifest.xml,like: <activity android:name = "com.your.packageName" android:screenOrientation="portrait" android:configChanges = "orientation"/>
then you can use it.

Answer 3

Check your manifest file for a entry of the activity. Check the name.

If you updated ADT to rev 22. you can try this java.lang.ClassNotFoundException after changing nothing in the project but upgrading eclipse android sdk .

Check the package name in manifest

    <manifest package="com.example.mypackaganame" //check the name

Check under application tag for the activity entry

    <activity
        android:name="com.example.mypackaganame.MainActivity"
        // this is the main activity
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

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

Say you have second Activity. This how you declare for implicit intents

     <activity
        android:name="com.example.mypackaganame.SecondActivity"
        // this is the Second activity
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="com.example.mypackaganame.SecondActivity" />

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

Foe explicit intents

      <activity
        android:name=".SecondActivity"
        // this is the Second activity
        android:label="@string/app_name" >
    </activity>           

Answer 4

If you are using Eclipse follow these steps :

Step 1. Go to Java Compiler and make sure that Compiler compliance level is set to 1.6, otherwise the processor won't be activated

Step 2. Go to Java Compiler > Annotation Processing and choose Enable annotation processing

step 3. Go to Java Compiler > Annotation Processing > Factory Path and add the processor JAR : androidannotations-XXXjar.

step 4 Confirm the workspace rebuild
