对于我的项目,我所有的 java 类都在一个包中——com.example.android.bitmapfun
我的清单是:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.android.bitmapfun"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="15"
android:targetSdkVersion="15" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<application
android:description="@string/app_description"
android:hardwareAccelerated="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name" >
<activity
android:name="com.example.android.bitmapfun.ImageGridActivity"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name="com.example.android.bitmapfun.ImageDetailActivity"
android:label="@string/app_name"
android:theme="@style/AppTheme.FullScreen" >
</activity>
</application>
</manifest>
活动是:
package com.example.android.bitmapfun;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.FragmentTransaction;
public class ImageGridActivity extends FragmentActivity {
private static final String TAG = "ImageGridFragment";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if (getSupportFragmentManager().findFragmentByTag(TAG) == null) {
final FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
ft.add(android.R.id.content, new ImageGridFragment(), TAG);
ft.commit();
}
}
}

LogCat:这里
为什么 LogCat 在这里显示 ClassNotFoundException?我试过但无法清除错误。请任何想法来克服这个问题。
