应用程序只能在仿真器/手机的重启显示了强制关闭。它有两个广播接收器1来检查电话状态并接听电话和其他通知图标。接收机监控手机状态仅在启动时才会出现以下异常，否则应用程序可以正常工作。日志如下所示

请帮

public class AnsTheCallReceiver extends BroadcastReceiver { 

public static final String TAG = "Andros:AnsTheCall:receiver"; 
public selectedTabType attentFlag = selectedTabType.TYPE_INVALID; 

private Intent AnsTheCallServiceIntent = null; 
public String contactName = null; 
public String contactEmail = ""; 
public int PhoneNumberCount= 0; 

@Override 
public void onReceive(Context context, Intent intent) { 

    SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(context); 
    SharedPreferences.Editor editor = prefs.edit(); 
    // Check phone state 
    String phone_state = intent.getStringExtra(TelephonyManager.EXTRA_STATE); 
    String phoneNumber = intent.getStringExtra(TelephonyManager.EXTRA_INCOMING_NUMBER); 
    String lastPhoneNumber = null; 
    Log.i(TAG,"initialised the receiver"); 

    if (phone_state.equals(TelephonyManager.EXTRA_STATE_RINGING) && prefs.getBoolean("appEnabled", false)) { 
     int is_starred = isStarred(context, phoneNumber);

检查什么是com.andro.AnsTheCall.AnsTheCallReceiver.onReceive(AnsTheCallReceiver.java:37这是造成您服务，强制关闭。
