在2.3.5之前,我一直对此问题感到困惑,在我的同事的设备上,这似乎很好用。但是,就我而言,它现在永远不会触发。

我已经剥离了代码,并制作了一个非常简单的测试应用程序以查看发生了什么。基本上,即使adb / logcat似乎表明BroadcastReveiver的寄存器确实发生了,onReceive代码也似乎从未触发过。

这是我去过的简单代码:

<?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>


然后:

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");
}
}


最后

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");
     }
}
}


因此,这是一个非常简单的应用程序,应该只记录日志并告诉我什么时候触发BroadcastReceiver,但它根本不会触发。

任何人都可以建议出什么问题了,我检查了各种教程,检查了一下,因为我知道IceCreamSandwich是不同的,但是也尝试合并这些修复程序,但这也没有任何区别。

提前致谢!

最佳答案

主要问题是“ mysmstestcall”中的这一行是错误的:

if (intent.getAction() == SMS_RECEIVED)

应该更改为:

if (intent.getAction().equals(SMS_RECEIVED))
