VerifyError＆amp;找不到类twitter4j.TwitterFactory错误

标签： android twitter4j verifyerror

我现有的Twitter集成代码正在运行，但现在却抛出了这个错误： - 

11-11 02:30:34.835: E/dalvikvm(2278): Could not find class 'twitter4j.TwitterFactory', referenced from method com.myapp.TwitterApp.<init>

然后强制关闭此错误： - 

11-11 02:30:35.265: E/AndroidRuntime(2278): FATAL EXCEPTION: main
11-11 02:30:35.265: E/AndroidRuntime(2278): java.lang.VerifyError: com/myapp/TwitterApp

这是在这句话上抛出错误： - 

mTwitter = new TwitterApp(this, Share.twitter_consumer_key,
            Share.twitter_secret_key);

我的TwitterApp类代码是： -

我已经实现了在此stackoverflow问题上接受的相同代码： why TwitterApp give VerifyError?

即时通讯使用最新的twitter4j-core-3.0.5.jar和项目我的构建目标是API 8。

包括的罐子是： -

请帮我弄清楚问题。感谢
