我正在构建一个Android应用程序,我想向当前用户发送短信,然后使用BroadcastReceiver读取此短信的内容。目前短信已成功发送,但我的BroadcastReceiver无法正常工作。 我确实在manifest.xml中输入了正确的权限:
<uses-permission android:name="android.permission.SEND_SMS" />
<uses-permission android:name="android.permission.RECEIVE_SMS" />
以下是我片段的代码:
public class GetOtpFragment extends Fragment {
private SMSReceiver mSMSreceiver;
private VerificationActivity mActivity;
private EditText mPhoneNumber;
private Button mVerifyButton;
public GetOtpFragment() {
// Required empty public constructor
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mActivity = (VerificationActivity) getActivity();
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
return inflater.inflate(R.layout.fragment_get_otp, container, false);
}
@Override
public void onViewCreated(View view, Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
Bundle b = getArguments();
mPhoneNumber = (EditText) view.findViewById(R.id.phone_number);
mVerifyButton = (Button) view.findViewById(R.id.verify_phone_number_button);
// I register my receiver
IntentFilter intentFilter = new IntentFilter("android.provider.Telephony.SMS_RECEIVED");
mSMSreceiver = new SMSReceiver();
mActivity.registerReceiver(mSMSreceiver, intentFilter);
// verify phone number
mVerifyButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// this works
SmsManager sms = SmsManager.getDefault();
sms.sendTextMessage(mPhoneNumber.getText().toString(), null, "test", null, null);
}
});
}
@Override
public void onStop() {
super.onStop();
mActivity.unregisterReceiver(mSMSreceiver);
}
}
我的BroadcastReceiver:
public class SMSReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
// never called
Toast.makeText(context, "SMS received", Toast.LENGTH_LONG);
Log.d("---- smsreceiver ---", "in smsreceiver");
}
}
就像我说的那样,短信真的被发送了,我可以在短信应用中找到它,但是没有通知。问题是我的接收器从未被呼叫,没有日志,也没有吐司,我不知道为什么。是因为sendTextMessage
没有创建任何通知吗?
答案 0 :(得分:-1)
尝试注册清单上的意图,而不是以编程方式注册,看看您是否能够接收广播。
<receiver
android:name="com.example.SMSReceiver"
android:permission="android.permission.BROADCAST_SMS">
<intent-filter>
<action android:name="android.provider.Telephony.SMS_RECEIVED"/>
</intent-filter>
</receiver>
如果这不起作用,可能是因为某些其他应用程序在您执行之前捕获广播并使用它(因为SMS_RECEIVED
广播是有序广播),如果是这种情况则尝试添加{{1像这样的intent-filter:
android:priority="2147483000"
如果它确实有效,您可能会遇到 <intent-filter android:priority="2147483000">
<action android:name="android.provider.Telephony.SMS_RECEIVED"/>
</intent-filter>
的问题,请确保您的活动保持有效,直到收到短信为止。
