ActivityNotFoundException:无法找到显式活动类服务 [英] ActivityNotFoundException: Unable to find explicit activity class service

问题描述

这是MainActivity和RecorderService Java类文件的外观.我也添加了AndroidManifest文件.

This is how my MainActivity and RecorderService Java class files looks like. I'm adding the AndroidManifest file too.

MainAcitivity.java

protected void onCreate(Bundle savedInstanceState) {

      btnSendSOS.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                sendSMS();

                Intent intent = new Intent(getBaseContext(), RecorderService.class);
                intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                startActivity(intent);

                finish();

                new CountDownTimer(5000, 1000) {

                @Override
                public void onTick(long millisUntilFinished) {

                }

                @Override
                public void onFinish() {
                    stopService(new Intent(getApplicationContext(), RecorderService.class));
                }
            }.start();
      });


}

RecorderService.java

public class RecorderService extends Service {
     // Service code here
}

AndroidManifest.xml

<application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name=".MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

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

        <service android:enabled="true"
            android:name=".RecorderService" />
</application>

我已将服务添加到清单文件中.但仍然出现错误:android.content.ActivityNotFoundException: Unable to find explicit activity class {.RecorderService}; have you declared this activity in your AndroidManifest.xml?

I have added the service to the Manifest file. But still I'm getting the error: android.content.ActivityNotFoundException: Unable to find explicit activity class {.RecorderService}; have you declared this activity in your AndroidManifest.xml?

请帮帮我.预先感谢

推荐答案

RecorderService是服务.不是Activity.和Start Service一样

  Intent i = new Intent(MainActivity.this, RecorderService.class);
  startService(i);
