我写了一个可以接收短信的android应用程序。该应用程序正在工作。它可以接收短信，但每次安装时都是新鲜的。每次我从模拟器发送短信到应用程序（无需手动打开）它崩溃或强制关闭，但如果我手动打开它可以接收短信没有问题自定义短信接收器首次收到短信崩溃[Android]
这里是我的代码，如果应用程序接收短信它会这样做代码
public void onReceive(Context context, Intent intent) {
Bundle bundle = intent.getExtras();
SmsMessage [] msgs = null;
String messageReceived = "";
String senderPhoneNumber = null;
long senderTimestamp = 0;
String strTimestamp = null;
if (bundle != null) {
Object[] pdus = (Object[]) bundle.get("pdus");
msgs = new SmsMessage[pdus.length];
for (int i=0; i<msgs.length; i++) {
msgs[i] = SmsMessage.createFromPdu((byte[])pdus[i]);
messageReceived += msgs[i].getMessageBody().toString();
messageReceived += "\n";
}
senderPhoneNumber = msgs[0].getOriginatingAddress();
senderTimestamp = msgs[0].getTimestampMillis()/1000L;
strTimestamp = senderTimestamp + "";
if(MainActivity.active){
MainActivity.populateView(senderPhoneNumber, messageReceived, strTimestamp);
} else {
Intent i = new Intent(context,MainActivity.class);
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
MainActivity.populateView(senderPhoneNumber, messageReceived, strTimestamp);
context.startActivity(i);
}
}
}
请有人帮我这个。我想收到短信而无需手动打开它。

你可以提供堆栈跟踪，放置吗？ –
好吧，先生，我会重新启动我的模拟器 – something
@EuryPérezBeltré我包括堆栈跟踪 – something
