我得到活动未找到异常。它与我一起使用 f9 具有相同的意图和表现。但是当我在联系活动代码中进行更改时，就会开始出现异常。
现在联系活动代码如下

public class Contact extends Activity {



   // @TargetApi(5)
    @Override
    public void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);

            setContentView(R.layout.contactlist);



            Button btnSimple = (Button) findViewById(R.id.btnSimple);

            btnSimple.setOnClickListener(new OnClickListener() {



                public void onClick(View v) {



                    Toast.makeText(getApplicationContext(),

                            " You clicked Simple ListView button", Toast.LENGTH_SHORT).show();



                    Intent intent = new Intent(v.getContext(), Upload_Contacts.class);
            });
    }}
                    startActivityForResult(intent, 0);

                }

这是我的日志猫

12-03 03:42:50.952: W/ActivityManager(61): Activity idle timeout for HistoryRecord{407eb998 com.fyp.smb/.Contact}

这是我的意图。

Intent contact = new Intent("com.fyp.smb.CONTACTS");
                startActivity(contact);

这是清单

<activity
            android:name=".Contact"
            android:label="@string/title_activity_login" >
            <intent-filter>
                <action android:name="com.fyp.smb.CONTACTS" />

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

为什么会发生错误，请提供任何解决方案

不管你如何写意图？

Intent contact = new Intent(getApplicationContext(), Contact.class);
            this.startActivity(contact);
