私は、ボタンのクリックで、最初の1から2番目の活動を呼び出そう

、それは例外を与えて、強制的に活動を終了させます。私はAndroidManifest.xmlと両方のActivityクラスの関連部分を貼り付けた理由は、Android開発の初心者です。だから私が間違って何かをしている場合、または私が何かを逃している場合は、指摘します。 あなたのlogcatが完了していないので、あなたの第二の活性について

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

をカテゴリを追加：

Answer 1

YourClass.this.startActivity(callHttp);は仕事

編集を行います。私が推測することができます。

Intent callDownloadPage = new Intent(YOURCLASS.this, EasyUploadSendLink.class); 
      startActivityForResult(callDownloadPage, 0); 

はあなたが起動し、各意思のためのあなたのマニフェストに<activityを持っていることを確認してください。それは非常に重要です。
