问题
I've been puzzling over this one recently, prior to 2.3.5 this seems to work fine (on my colleagues devices). However on mine it now never triggers.
I've stripped the code right back and made a very simple test application to see what's going on. Basically the onReceive code doesn't ever appear to trigger, even though adb/logcat does seem to show the register of the BroadcastReveiver does take place.
Here's the simple code I've gone for:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.broadcasttech.testsmsreceive"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk android:minSdkVersion="9" />
<application
android:icon="@drawable/ic_launcher"
android:label="@string/app_name" >
<activity
android:label="@string/app_name"
android:name=".TestSMSReceiveActivity" >
<intent-filter >
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<receiver android:name=".mysmstestcall">
<intent-filter>
<action android:name="android.provider.Telephony.SMS_RECEIVED"></action>
</intent-filter>
</receiver>
</application>
<uses-permission android:name="android.permission.INTERNET"></uses-permission>
<uses-permission android:name="android.permission.RECEIVE_SMS"></uses-permission>
</manifest>
Then:
package com.broadcasttech.testsmsreceive;
import android.app.Activity;
import android.content.BroadcastReceiver;
import android.content.IntentFilter;
import android.os.Bundle;
import android.util.Log;
public class TestSMSReceiveActivity extends Activity {
private BroadcastReceiver receiver;
private static final String TAG = "TestSMSApp";
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Log.i(TAG, " App has started up");
IntentFilter filter = new IntentFilter();
filter.addAction("android.provider.Telephony.SMS_RECEIVED");
Log.i(TAG, " Filter SMS_RECEIVED has been added");
//Extends BroadcastReceiver
receiver = new mysmstestcall();
registerReceiver(receiver,filter);
Log.i(TAG, " registerReceiver sorted");
}
//Also, to save headaches later
@Override
protected void onDestroy() {
Log.i(TAG, " unregistering Receiver");
unregisterReceiver(receiver);
Log.i(TAG, " done");
}
}
And finally
package com.broadcasttech.testsmsreceive;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.util.Log;
public class mysmstestcall extends BroadcastReceiver {
private static final String SMS_RECEIVED = "android.provider.Telephony.SMS_RECEIVED";
private static final String TAG = "TestSMSApp";
@Override
public void onReceive(Context context, Intent intent) {
Log.i(TAG, "Intent recieved: " + intent.getAction());
if (intent.getAction() == SMS_RECEIVED) {
//any action you want here..
Log.i(TAG, "SMS received has triggered");
}
}
}
So it is a fairly simple app that should just log and tell me when the BroadcastReceiver is triggered, but it just won't fire at all.
Can anyone suggest whats wrong, I've checked various tutorials, checked as I know IceCreamSandwich is different, but tried to incorporate those fixes too and this doesn't make a difference either.
Thanks in advance!
回答1:
The main problem is that this line in "mysmstestcall" is wrong:
if (intent.getAction() == SMS_RECEIVED)
should be changed to this:
if (intent.getAction().equals(SMS_RECEIVED))

Is there a reason that you have two recievers? You have a programatic listener and you have an XML listener
Programatic:
filter.addAction("android.provider.Telephony.SMS_RECEIVED");
Log.i(TAG, " Filter SMS_RECEIVED has been added");
//Extends BroadcastReceiver
receiver = new mysmstestcall();
XML Listener:
<receiver android:name=".mysmstestcall">
<intent-filter>
<action android:name="android.provider.Telephony.SMS_RECEIVED"></action>
</intent-filter>
Are you sure you want these two? If you have two you will RECEIVE the same broadcast 2 times...
As for another ISSUE that I see is this line
if (intent.getAction() == SMS_RECEIVED)
When comparing strings you DO NOT compare them like this instead you'd have something like this:
if (intent.getAction().equalsIgnoreCase(SMS_RECEIVED))

I've got this once. It can be network's issue. These were my question and answer. You can add a sending intent and catch the result code. In my case, it was RESULT_ERROR_GENERIC_FAILURE. I tried to find other solutions for months but no luck, so I accepted that even though I don't want to :-(
