無法啓動服務Intent {flg = 0x4 cmp = com.org.sample/.TipActivity（has extras）} U = 0：未找到

Question

我知道很多人都遇到過這個問題，但我嘗試了所有的堆棧溢出建議。

1. 使封裝名小

2. 在清單驗證的服務和更多的，但仍然我不能夠解決這個問題。

3. 應用程序清潔和構建。

但沒有任何工作。點擊startservice按鈕，服務啓動，警報設置和意圖不調用。無法啓動服務意圖。

這是我的代碼。

MainActivity.java

public class MainActivity extends AppCompatActivity { 

    Button btnStartService; 
    Button btnStopService; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 
     btnStartService = (Button)findViewById(R.id.btn_startService); 
     btnStopService = (Button)findViewById(R.id.btn_stopService); 

     btnStartService.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       startService(); 
      } 
     }); 

     btnStopService.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       stopService(); 
      } 
     }); 
    } 

    // Method to start the service 
    public void startService() { 
     startService(new Intent(getBaseContext(), Backgroundservice.class)); 
    } 

    // Method to stop the service 
    public void stopService() { 
     stopService(new Intent(getBaseContext(), Backgroundservice.class)); 
    } 

    @Override 
    public boolean onCreateOptionsMenu(Menu menu) { 
     // Inflate the menu; this adds items to the action bar if it is present. 
     getMenuInflater().inflate(R.menu.menu_main, menu); 
     return true; 
    } 

    @Override 
    public boolean onOptionsItemSelected(MenuItem item) { 
     // Handle action bar item clicks here. The action bar will 
     // automatically handle clicks on the Home/Up button, so long 
     // as you specify a parent activity in AndroidManifest.xml. 
     int id = item.getItemId(); 

     //noinspection SimplifiableIfStatement 
     if (id == R.id.action_settings) { 
      return true; 
     } 

     return super.onOptionsItemSelected(item); 
    } 
} 

後臺服務

public class Backgroundservice extends Service { 

    private AlarmManager alarmManager; 
    private PendingIntent pendingIntent; 

    public Backgroundservice() { 
    } 

    @Override 
    public IBinder onBind(Intent intent) { 
     // TODO: Return the communication channel to the service. 
     throw new UnsupportedOperationException("Not yet implemented"); 
    } 

    @Override 
     public int onStartCommand(Intent intent, int flags, int startId) { 
     Toast.makeText(this, "Service Started!", Toast.LENGTH_LONG).show(); 
     DateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss"); 
     Date date = new Date(); 
     System.out.println("*****" + dateFormat.format(date)); 
     startAlarm(); 
     return START_STICKY; 
    } 

    @Override 
    public void onDestroy() { 
     super.onDestroy(); 
     stopAlarm(); 
     Toast.makeText(this,"Service Stopped!",Toast.LENGTH_LONG).show(); 
    } 

    public void startAlarm() 
    { 
     Calendar calendar = Calendar.getInstance(); 
     calendar.setTimeInMillis(System.currentTimeMillis()); 
     calendar.set(calendar.HOUR_OF_DAY,13); 
     calendar.set(calendar.MINUTE,20); 
     calendar.set(Calendar.SECOND,10); 

     alarmManager = (AlarmManager)getSystemService(Context.ALARM_SERVICE); 
     Intent intent = new Intent(this,TipActivity.class); 
     pendingIntent = PendingIntent.getService(this,0, intent, 0); 

     alarmManager.setInexactRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pendingIntent); 
     Toast.makeText(this, "Alarm Set", Toast.LENGTH_SHORT).show(); 
    } 

    public void stopAlarm(){ 

     if (alarmManager != null) 
     { 
      alarmManager.cancel(pendingIntent); 
      Toast.makeText(this, "Alarm Cancelled", Toast.LENGTH_SHORT).show(); 
     } 
    } 

} 

TipActivity，JAVA

public class TipActivity extends AppCompatActivity { 

    Button btnDismiss; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_tip); 

     btnDismiss = (Button) findViewById(R.id.dismiss); 

     btnDismiss.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       finish(); 
      } 
     }); 
    } 

    @Override 
    public boolean onCreateOptionsMenu(Menu menu) { 
     // Inflate the menu; this adds items to the action bar if it is present. 
     getMenuInflater().inflate(R.menu.menu_tip, menu); 
     return true; 
    } 

    @Override 
    public boolean onOptionsItemSelected(MenuItem item) { 
     // Handle action bar item clicks here. The action bar will 
     // automatically handle clicks on the Home/Up button, so long 
     // as you specify a parent activity in AndroidManifest.xml. 
     int id = item.getItemId(); 

     //noinspection SimplifiableIfStatement 
     if (id == R.id.action_settings) { 
      return true; 
     } 

     return super.onOptionsItemSelected(item); 
    } 
} 

的AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?> 
<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
    package="com.org.sample" > 

    <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:name=".Backgroundservice" 
      android:enabled="true" 
      android:exported="true" > 
     </service> 

     <activity 
      android:name=".TipActivity" 
      android:label="@string/title_activity_tip" 
      > 
     </activity> 
    </application> 

</manifest> 

我在這方面做了很多工作以解決問題，但徒勞無功。

您的幫助真的很感謝。

用PendingIntent.getActivity（）複製PendingIntent.getService。
