MANIFEST FILE，错误在活动中保存：

`

 </manifest> `

JAVA文件我开始活动的块，必须打开的java文件是SAve.java：

    ` Show.setOnClickListener(new View.OnClickListener() {

                  @Override
                  public void onClick(View arg0) {
                  // TODO Auto-generated method stub

                     Intent i= new Intent("shurukaro");
                     startActivity(i);


        }
    });`

Answer 1

尝试删除。您是否希望每次启动应用时都将.SAve作为主要活动开始？

<intent-filter>
              <action android:name="shurukaro" />

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

        </intent-filter>

无法实例化活动componentinfo;已检查android清单
