Question

应用程序仅在重启模拟器/手机时显示强制关闭。它有两个广播接收器1来检查电话状态并接听电话，另一个用于保持通知图标在上面。接收器监视电话状态仅在启动时提供以下异常，否则应用程序正常工作。日志如下所示

请帮忙

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com.andro.AnsTheCall.AnsTheCallReceiver.onReceive(AnsTheCallReceiver.java:37这导致您的服务强制关闭的内容。

12：48：15.827：ERROR / AndroidRuntime（218）：引起： java.lang.NullPointerException 05-20 12：48：15.827：错误/ AndroidRuntime（218）：at com.andro.AnsTheCall.AnsTheCallReceiver.onReceive（AnsTheCallReceiver.java:37） 05-20 12：48：15.827：

应用程序显示强制关闭仅在启动模拟器/电话时，因为广播接收器显示异常
