服务无法启动其他应用程序的活动

我有一个应用程序“x”按钮单击启动服务（在某些其他程序包中）。此服务现在应该读取通话记录并将数据发送到应该将数据写入SD卡的应用程序“y”。目前，我的服务运行在点击按钮上，但应用程序“y”并不像我在应用程序“y”中拥有一杯祝酒，而且它永远不会出现。读取日志时会给出权限，并且因为使用自定义操作，所以应用程序“y”的意图过滤器中也包含相同的权限。有人能说出这个问题的原因吗？服务无法启动其他应用程序的活动

服务代码

public int onStartCommand(Intent intent, int flags, int startId) { 
     Log.d("TAG", "Service started."); 
     super.onStartCommand(intent, flags, startId); 
     StringBuffer sb = new StringBuffer(); 
     String strOrder = android.provider.CallLog.Calls.DATE + " DESC"; 
    /* Query the CallLog Content Provider */ 
     if (ActivityCompat.checkSelfPermission(this, Manifest.permission.READ_CALL_LOG) != PackageManager.PERMISSION_GRANTED) { 
      // TODO: Consider calling 
      // ActivityCompat#requestPermissions 
      // here to request the missing permissions, and then overriding 
      // public void onRequestPermissionsResult(int requestCode, String[] permissions, 
      //           int[] grantResults) 
      // to handle the case where the user grants the permission. See the documentation 
      // for ActivityCompat#requestPermissions for more details. 
      return 0; 
     } 
     Cursor managedCursor = getContentResolver().query(CallLog.Calls.CONTENT_URI, null, 
       null, null, strOrder); 
     int number = managedCursor.getColumnIndex(CallLog.Calls.NUMBER); 
     int type = managedCursor.getColumnIndex(CallLog.Calls.TYPE); 
     int date = managedCursor.getColumnIndex(CallLog.Calls.DATE); 
     int duration = managedCursor.getColumnIndex(CallLog.Calls.DURATION); 
     sb.append("Call Log :"); 
     int h = 0; 
     while (managedCursor.moveToNext() && h != 20) { 
      String phNum = managedCursor.getString(number); 
      String callTypeCode = managedCursor.getString(type); 
      String strcallDate = managedCursor.getString(date); 
      Date callDate = new Date(Long.valueOf(strcallDate)); 
      String callDuration = managedCursor.getString(duration); 
      String callType = null; 
      h++; 
      int callcode = Integer.parseInt(callTypeCode); 
      switch (callcode) { 
       case CallLog.Calls.OUTGOING_TYPE: 
        callType = "Outgoing"; 
        break; 
       case CallLog.Calls.INCOMING_TYPE: 
        callType = "Incoming"; 
        break; 
       case CallLog.Calls.MISSED_TYPE: 
        callType = "Missed"; 
        break; 
      } 
      sb.append("\nPhone Number:--- " + phNum + " \nCall Type:--- " 
        + callType + " \nCall Date:--- " + callDate 
        + " \nCall duration in sec :--- " + callDuration); 
      sb.append("\n----------------------------------"); 
     } 
     managedCursor.close(); 
     managedCursor.close(); 
    Intent sendIntent = new Intent(); 
    String CUSTOM_ACTION = "com.example.sonali.callreadingservice.CALL_LOGS"; 
    sendIntent.setAction(CUSTOM_ACTION); 
    sendIntent.putExtra(Intent.EXTRA_TEXT, (Serializable) sb); 
    sendIntent.setType("text/plain"); 
    startActivity(sendIntent); 
    this.stopSelf(); 
    return 0; 
    } 

    @Override 
    public void onDestroy() { 
     Log.d("slog", "onDestroy()"); 
     super.onDestroy(); 
    }

应用 “y” 的主要活动

``public class MainActivity extends AppCompatActivity { 
    TextView textView = null; 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 
     Toast.makeText(this, "Service Started", Toast.LENGTH_SHORT).show(); 
     textView = (TextView) findViewById(R.id.textview_call); 
     Intent intent = getIntent(); 
     String action = intent.getAction(); 
     String type = intent.getType(); 
     handleSendText(intent); 

     } 


    void handleSendText(Intent intent) { 
     String sharedText = intent.getStringExtra(Intent.EXTRA_TEXT); 
     try { 
      if (sharedText != null) { 
       textView.setText(sharedText); 
       File sdCard = Environment.getExternalStorageDirectory(); 
       FileWriter writer = new FileWriter(sdCard); 
// Writes the content to the file 
       writer.write(sharedText); 
       writer.flush(); 
       writer.close(); 
      } 
     } catch (Exception e) { 

     } 
    }

应用的意图过滤器 “Y” `

`<intent-filter> 
       <action android:name="com.example.sonali.callreadingservice.CALL_LOGS" /> 
       <category android:name="android.intent.category.LAUNCHER" /> 
       <data android:mimeType="text/plain" /> 
      </intent-filter>

您是否定义了要从服务清单内的应用程序Y运行的活动？ –

你需要什么服务？只是发送'Cursor'的数据？为什么不使用“ContentProvider”？ – pskink

@MuhammedRefaat不，我没有。你能告诉我怎么写吗？ –

您需要添加自定义操作在活动的清单中。

<activity 
     android:name="MainActivity"> 
     <intent-filter> 
      <action android:name="com.example.sonali.callreadingservice.CALL_LOGS"/> 
     </intent-filter> 
    </activity>

是的，我已经完成了这项工作 –

您还需要为意图过滤器添加默认类别。 –

有2个intent过滤器，并且在我已经添加了 –
