安卓的BroadcastReceiver没有停止摄像机意向行动 [英] Android BroadcastReceiver not stopping Camera Intent action

问题描述

我想'块'的摄像头动作，而我的应用程序被激活。在的onReceive 的方法被在BroadcastReceiver的执行，而是由LogCat中这似乎是在做意向已经执行打完。

解决方案

其实我能够加入到这样做

 ＆LT;类机器人：名称=android.intent.category.DEFAULT/＆GT;
 

我的意图FITER，所以它看起来像：

 ＆LT;接收器的Andr​​oid版本：NAME =com.receiver.CameraReceiver＆GT;
    ＆LT;意向滤光器＆gt;
        ＆lt;作用机器人：名称=android.intent.action.CAMERA_BUTTON/＆GT;
        ＆LT;类机器人：名称=android.intent.category.DEFAULT/＆GT;
    ＆所述; /意图滤光器＆gt;
＆LT; /接收器＆GT;
 

这似乎是工作，任何人都可以发表评论我要，如果这还是机器人：优先级的正确方法

另外，如果我能阻止'震动'是发生在鼠标preSS这将是有益的。

谢谢！

I am trying to 'block' the Camera action while my application is active. The onReceive method is being executed on the BroadcastReceiver, but by the LogCat it seems to be doing so after the Intent has already been executed.

    </application>


</manifest>

com.receiver.CameraReceiver

package com.receiver;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.util.Log;

public class CameraReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        Log.i(this.toString(), "Suck It Android!");
        abortBroadcast();
    }

    @Override
    public String toString() {
        return "com.receiver.CameraReceiver";
    }
}

解决方案

Actually I was able to do it by adding

<category android:name="android.intent.category.DEFAULT" />

to my intent fiter, so it looks like:

<receiver android:name="com.receiver.CameraReceiver">
    <intent-filter>
        <action android:name="android.intent.action.CAMERA_BUTTON" />
        <category android:name="android.intent.category.DEFAULT" />
    </intent-filter>
</receiver>

and this seems to be working, can anybody comment to if this or the android:priority is the proper way.

Also, if I can stop the 'Vibrate' that happens on button press that would be helpful.

Thanks!
