我的应用程序是关于通过短信收到铃声模式的手机,但它的工作完成后崩溃显示"不幸的是,你的应用程序已停止响应.."。这是我的manifest和receiver.java文件

MYReceiver.java
public class MyReceiver extends BroadcastReceiver{
LocationManager lm;
LocationListener locationListener;
String sender;
@Override
public void onReceive(Context context, Intent intent) {
SmsMessage[] sms = null;
Bundle b = intent.getExtras();
String str = " SMS From ";
if (b != null) {
Object[] pdus = (Object[]) b.get("pdus");
sms = new SmsMessage[pdus.length];
for (int i = 0; i < sms.length; i++) {
sms[i] = SmsMessage.createFromPdu((byte[]) pdus[i]);
if (i == 0) {
sender += sms[i].getOriginatingAddress();
str += ":"+sms[i].getMessageBody().toString();
if (sms[i].getMessageBody().equals("Ring")) {
AudioManager am = (AudioManager)context.getSystemService(Context.AUDIO_SERVICE);
int maxVolume = am.getStreamMaxVolume(AudioManager.STREAM_RING);
am.setRingerMode(AudioManager.RINGER_MODE_NORMAL);
am.setStreamVolume(AudioManager.STREAM_RING, maxVolume,AudioManager.FLAG_SHOW_UI + AudioManager.FLAG_PLAY_SOUND);
}
}
}
Toast.makeText(context, str, Toast.LENGTH_SHORT).show();
Log.d("Receiving", str);
}
}
}
在日志中导致的更多内容显示为NULLPOINTEREXCEPTION(),但我没有得到没有引发异常的代码。 但它工作正常,只要我在其他应用程序上收到消息,它就会显示不幸的消息。
