android - 从收听拨出电话的广播接收器启动 Activity

Question

我正在尝试从广播接收器启动一个 Activity ，该接收器监听 5556 的拨出电话。问题是，该 Activity 未启动，但正在调用拨号内置 Activity ，我已经更改了 Intent 的优先级到 100 但无济于事。如何让 Activity 在拨号时启动而不是内置调用 Activity ？ 这是代码:

package com.messageHider;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.widget.Toast;

public class launchReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        String number=intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);
        String compare_num="5556";
        if(number.equals(compare_num))
        {
            Intent myintent=new Intent(context,messageHider.class);
            myintent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            context.startActivity(myintent);
            abortBroadcast();
        }
    }

}

list 文件:

<receiver android:name=".launchReceiver">
    <intent-filter android:priority="0">
        <action android:name="android.intent.action.NEW_OUTGOING_CALL"/>
    </intent-filter>
</receiver>

Answer 1

在您的 list 中，您需要一个权限(根据文档):

You must hold the PROCESS_OUTGOING_CALLS permission to receive this Intent.

那就是

"android.permission.PROCESS_OUTGOING_CALLS"

也直接来自文档:

Any BroadcastReceiver receiving this Intent must not abort the broadcast.

这是我获得信息的页面链接:
