找不到Android活动异常

Question

I am receiving this erro message in my logcat:

10-19 21:00:08.672: E/AndroidRuntime(808): FATAL EXCEPTION: main
10-19 21:00:08.672: E/AndroidRuntime(808): java.lang.RuntimeException: Unable to instantiate activity ComponentInfo{com.minyanapp.activities/com.minyanapp.activities.SplashActivity}: java.lang.ClassNotFoundException: com.minyanapp.activities.SplashActivity

also, before the above message I get this error:

10-19 22:07:13.003: E/Trace(1157): error opening trace file: No such file or directory (2)

Here is my Manifest.xml file:

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name="com.minyanapp.activities.SplashActivity"
        android:label="@string/title_activity_splash" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity
        android:name="com.minyanapp.activities.MainActivity"
        android:label="@string/title_activity_main" >
    </activity>
    <activity
        android:name="com.minyanapp.activities.Dummy"
        android:label="@string/title_activity_dummy" >
    </activity>
</application>

I tried to delete gen and bin folders, restart eclipse and emulator. Nothing helped.

Help please!!!

Answer 1

I just reproduced the problem on my machine. Here is what I did :

In file MyAndroid\\bin\\AndroidManifest.xml my class is com.example.myandroid.MainActivity . While in MyAndroid\\AndroidManifest.xml my class is com.example.myandroid.LunchActivity

Then I get :

10-19 21:21:15.180: E/AndroidRuntime(1103): java.lang.RuntimeException: Unable to instantiate activity ComponentInfo{com.example.myandroid/com.example.myandroid.MainActivity}: java.lang.ClassNotFoundException: Didn't find class "com.example.myandroid.MainActivity" on path: /data/app/com.example.myandroid-1.apk

Changing both Manifest.xmls would resolve the issue.

In splashactivitie.java the first line of code is package com.minyanapp.activities ; right? The class file splasplashactivites.class is in the bin folder,right? Meaning it is compiling, probably is if you got logcat message.

我决定删除项目并复制所有类，布局等。
