我正在尝试在应用程序上创建。我需要检测我是否接到任何电话,然后获取号码,但是这个过程应该在后台进行。
后台工作是后期工作,但现在我正在尝试启动我的应用程序,但它崩溃了。
你能告诉我如何在背景中调用broadcastreciver吗? 这里是我的MainActivity.java如何检测后台来电
public class MainActivity extends Activity
{
@Override
public void onCreate(Bundle savedInstancestate)
{
super.onCreate(savedInstancestate);
setContentView(R.layout.activity_main);
}
public void broadcastIntent(View view)
{
Intent intent = new Intent();
intent.setAction("com.app.callrecord.MyBroadcastReceiver");
sendBroadcast(intent);
}
}
Broadcastreceiver.java
public class MyBroadcastReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
Bundle bundle = intent.getExtras();
if (bundle == null)
return;
String phoneNumber = null;
// Incoming call
String state = bundle.getString(TelephonyManager.EXTRA_STATE);
if ((state != null) && (state.equalsIgnoreCase(TelephonyManager.EXTRA_STATE_RINGING))) {
phoneNumber = bundle.getString(TelephonyManager.EXTRA_INCOMING_NUMBER);
// callToast(phoneNumber);
}
// Outgoing call
else if (state == null) {
Intent i = new Intent(context,RecordHistory.class);
intent.putExtra("phonenumber", phoneNumber);
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(i);
// Here: do something with the number
}
}
}
这里是我的清单文件
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<receiver android:name="com.app.callrecord.MainActivity">
<intent-filter>
<action android:name="android.intent.action.PHONE_STATE"></action>
<action android:name="android.intent.action.NEW_OUTGOING_CALL"></action>
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".RecordHistory"></activity>
</application>
而且这里是我的例外日志

给我任何参考。
谢谢您的回答,但是当我启动的应用程序可以在我的手机打电话我没拿到,我用它来显示号码的任何祝酒。 .. – 2013-02-18 08:22:45
这可能是由于缺少权限。我编辑了答案。 – Tomik 2013-02-18 08:49:08
