java ANDROID：如何接收特定应用程序通知的广播？

# 1 楼答案

您可以查看状态栏通知，但无法读取它们。如果可能的话，这对脆弱性来说真的很危险

但是使用Accessibility Service，您只能侦听通知栏上的所有通知。

# 2 楼答案

尝试此操作以访问任何应用程序的通知表单

    import android.accessibilityservice.AccessibilityService;
    import android.accessibilityservice.AccessibilityServiceInfo;
    import android.app.Notification;
    import android.media.AudioManager;
    import android.os.Parcelable;
    import android.util.Log;
    import android.view.accessibility.AccessibilityEvent;
    import com.qna.vbage.Pref;
    import static com.qna.vbage.FieldVerification.setRingerMode;


    public class NotificationService extends AccessibilityService {


        protected void onServiceConnected() {
            AccessibilityServiceInfo info = new AccessibilityServiceInfo();
            info.eventTypes = AccessibilityEvent.TYPE_NOTIFICATION_STATE_CHANGED;
            info.feedbackType = AccessibilityServiceInfo.FEEDBACK_ALL_MASK;
            info.notificationTimeout = 3000;
            setServiceInfo(info);
        }

        @Override
        public void onAccessibilityEvent(AccessibilityEvent e) {
            //Toast.makeText(this, "onAccessibilityEvent", Toast.LENGTH_SHORT).show();
            Log.d("VBage", "FML");
            if (e.getEventType() == AccessibilityEvent.TYPE_NOTIFICATION_STATE_CHANGED) {
               // Toast.makeText(this, "onAccessibilityEvent 2", Toast.LENGTH_SHORT).show();
                Log.d("VBage", "Recieved event");
                Parcelable data = e.getParcelableData();
                if (data instanceof Notification) {
                   // Toast.makeText(this, "onAccessibilityEvent 3", Toast.LENGTH_SHORT).show();
                    Log.d("VBage", "Recieved notification");
                    Notification notification = (Notification) data;
                    Log.d("VBage", "ticker: " + notification.tickerText);
                    Log.d("VBage", "icon: " + notification.icon);
                    Log.d("VBage", "notification: " + e.getText());     
                }
            }
        }

        @Override
        public void onInterrupt() {
            setRingerMode(NotificationService_API18.this, AudioManager.RINGER_MODE_SILENT);
        }
    }

在清单中设置权限

<uses-permission
    android:name="android.permission.BIND_ACCESSIBILITY_SERVICE"
    tools:ignore="ProtectedPermissions" />

将清单中的服务设置为在应用程序启动时调用

   <service android:name=".NotificationService"
            android:label="@string/app_name"
            android:permission="android.permission.BIND_ACCESSIBILITY_SERVICE" >
            <intent-filter>
                <action android:name="android.accessibilityservice.AccessibilityService" />
            </intent-filter>

            <meta-data
                android:name="android.accessibilityservice"
                android:resource="@xml/accessibilityservice" />
        </service>

在您的值文件夹中创建xmlres/Values/xml/accessibilityservice。xml

<?xml version="1.0" encoding="utf-8"?>
<accessibility-service xmlns:android="http://schemas.android.com/apk/res/android"
    android:accessibilityEventTypes="typeNotificationStateChanged"
    android:accessibilityFeedbackType="feedbackSpoken"
    android:notificationTimeout="100" />

您必须手动启用应用程序的可访问性，并将代码放在您要开始使用此服务的活动中

if (!isAccessibilitySettingsOn(getApplicationContext())) {
            AlertDialog.Builder dialog = new AlertDialog.Builder(mActivity);
            dialog.setNegativeButton("Go!", new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                    dialog.dismiss();
                   startActivity(new Intent(Settings.ACTION_ACCESSIBILITY_SETTINGS));
                }
            });
            showCusDialog(dialog, "Warning!", R.drawable.ic_warning, getString(R.string.accessiblityString));

        }

从活动开始服务

startService(new Intent(mActivity, NotificationService_API18.class));

Simple只需遵循此代码并阅读此link中的文档

清单文件

    <receiver android:name=".callbroadcastreceiver"
        android:exported="true"
        android:enabled="true">
        <intent-filter>
            <action android:name="android.intent.action.PHONE_STATE"/>
        </intent-filter>
    </receiver>

在Java callbroadcastreceiver文件中

公共类callbroadcastreceiver扩展了BroadcastReceiver
{

@Override
public void onReceive(Context context, Intent intent) {

    String state = intent.getStringExtra( TelephonyManager.EXTRA_STATE);

    if (state.equals(TelephonyManager.EXTRA_STATE_RINGING)) {
        //Phone is ringing
    }
    else if (state.equals(TelephonyManager.EXTRA_STATE_OFFHOOK)) {
        //Call received
        Toast.makeText( context,"call received",Toast.LENGTH_SHORT ).show();
        context.startService( new Intent( context,BoundService.class ) );
    }
    else if (state.equals( TelephonyManager.EXTRA_STATE_IDLE)) {
        //Call Dropped or rejected
        context.stopService(  new Intent( context,BoundService.class ) );
    }
}

}

您可以为此创建一个NotificationListenerService。不过，用户可能对授予应用程序监视其通知的权限不感兴趣，这就是为什么用户必须为应用程序手动启用此功能的原因

但是你不能阅读内容
