我最近一直对此感到困惑，在 2.3.5 之前，这似乎工作正常（在我同事的设备上）。然而，在我的身上，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来查看发生了什么。基本上 onReceive 代码似乎永远不会触发，即使 adb/logcat 似乎确实显示了 BroadcastReveiver 的寄存器确实发生了。
这是我使用的简单代码：
<?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");
}
}
}
所以这是一个相当简单的应用程序，它应该只记录并告诉我何时触发 BroadcastReceiver，但它根本不会触发。
任何人都可以提出什么问题吗，我检查了各种教程，检查了我知道 IceCreamSandwich 是不同的，但也尝试合并这些修复程序，这也没有什么不同。
提前致谢！
