【问题描述】:
我想在 android 中获取被叫号码,但是当我开始拨出电话时它失败了
Menifest.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.vampirepc.androidservice" >
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:supportsRtl="true"
android:theme="@style/AppTheme" >
<activity android:name=".MainActivity" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
<action android:name="android.intent.action.BOOT_COMPLETED">
<action android:name="android.intent.action.NEW_OUTGOING_CALL" />
</action>
</intent-filter>
</activity>
<service android:name=".MyService" />
<receiver
android:name="com.example.vampirepc.androidservice.OutgoingReceiver"
android:enabled="true"
android:exported="true" >
<intent-filter>
<action android:name="android.intent.action.NEW_OUTGOING_CALL" />
</intent-filter>
</receiver>
</application>
<uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS" />
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
</manifest>
BroadcastReceiver 类
@Override
public void onReceive(Context context, Intent intent) {
Toast.makeText(ctx,
"Inside broadcast",
Toast.LENGTH_LONG).show();
String phoneNumber = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);
Toast.makeText(context, "Outgoing call catched: " + phoneNumber, Toast.LENGTH_LONG).show();
}
服务
@Override
public void onCreate() {
Toast.makeText(getApplicationContext(),"Service created",Toast.LENGTH_SHORT).show();
try {
IntentFilter filter = new IntentFilter("android.intent.action.NEW_OUTGOING_CALL");
OutgoingReceiver myReceiver = new OutgoingReceiver();
registerReceiver(myReceiver, filter);
} catch (Exception e) {
Toast.makeText(getApplicationContext(),"Exception is "+String.valueOf(e),Toast.LENGTH_SHORT).show();
}
}
【问题讨论】:
-
在您的情况下,无需在运行时注册接收器,只需在清单中定义即可。
-
当我拨打号码时仍然无法正常工作应用程序停止工作
-
请发布堆栈跟踪。
-
当我删除 onReceive 方法中的所有代码时,它不会停止应用程序。
-
我认为问题出在 Toast 上。
